摘要的摘要
世界正以惊人的速度消耗其自然资源,这已导致资源价值发生了永久性转变。我们所有人都需要调整自身行为,以适应这一新环境。如果我们能迅速行动,将会有所帮助。
摘要
■ 直到 1800 年左右,人类这个物种没有任何安全余量,像其他动物一样,生活在食物供应的极限边缘,人口数量涨涨落落。
■ 从 1800 年左右开始,碳氢化合物的使用使得能源使用量、食物供给量出现了爆炸式增长,并且通过创造盈余,带来了财富和科学进步的急剧增长。
■ 自 1800 年以来,人口已从 8 亿激增至 70 亿,并正朝着至少 80 亿的估计值迈进。
■ 人口的增长、发达国家财富的 10 倍增长,以及当前发展中国家的爆炸式增长,已迅速消耗着我们有限的碳氢化合物、金属、化肥、可用土地和水资源。
■ 现在,尽管化肥使用量大幅增加,但每英亩作物产量的增长率已从 20 世纪 60 年代的 3.5% 下降至今天的 1.2%。几乎没有新的可垦土地可以投入,而且随着人们越来越富有,他们会消费更多以谷物密集型方式生产的肉类。由于人口增长率仍超过 1%,几乎没有什么安全余量。
■ 在资源有限的情况下,复利式增长所带来的问题,乐观、短视且相对不擅长数字的人类(尤其是政治人物)并不容易理解。
■ 事实是,没有任何复利式增长是可持续的。如果我们继续执着于增长,我们将耗尽一切,最终崩盘。我们必须用质的增长取代量的增长。
■ 但市场先生正在帮忙,此刻她正向我们发出有史以来最强烈的价格信号。从 1800 年到 2002 年的 100 年间,除石油外的所有重要大宗商品价格均告下跌,平均跌幅达 70%。从 2002 年至今,这一整个跌幅已被一次比第二次世界大战期间更为猛烈的价格飙升所抹平。
■ 从统计学上看,多数大宗商品目前的价格已远远偏离其以往的下跌趋势,这使得旧有趋势很可能已经改变——事实上,可能正在发生一个“范式转换”——这或许是自工业革命以来最重要的经济事件。
■ 气候变化与天气不稳定相关,但去年情况异常糟糕。短期内,情况肯定会有所好转。
■ 资源和资源效率方面极佳的长期投资机会,因明年天气改善的可能性很高以及中国经济可能受挫而大打折扣。
■ 从现在起,资源的价格压力和短缺将成为我们生活中一个永久特征。这将越来越严重地拖慢发达国家和发展中国家的增长速度,并给贫困国家带来沉重负担。
■ 我们都需要制定严肃的资源计划,尤其是能源政策。时间所剩无几。
GMO QUARTERLY LETTER April 2011 Time to Wake Up: Days of Abundant Resources and Falling Prices Are Over Forever Jeremy Grantham Summary of the Summary The world is using up its natural resources at an alarming rate, and this has caused a permanent shift in their value. We all need to adjust our behavior to this new environment. It would help if we did it quickly. Summary Until about 1800, our species had no safety margin and lived, like other animals, up to the limit of the food supply, ebbing and flowing in population. From about 1800 on the use of hydrocarbons allowed for an explosion in energy use, in food supply, and, through the creation of surpluses, a dramatic increase in wealth and scientific progress. Since 1800, the population has surged from 800 million to 7 billion, on its way to an estimated 8 billion, at minimum. The rise in population, the ten-fold increase in wealth in developed countries, and the current explosive growth in developing countries have eaten rapidly into our finite resources of hydrocarbons and metals, fertilizer, available land, and water. Now, despite a massive increase in fertilizer use, the growth in crop yields per acre has declined from 3.5% in the 1960s to 1.2% today. There is little productive new land to bring on and, as people get richer, they eat more grain-intensive meat. Because the population continues to grow at over 1%, there is little safety margin. The problems of compounding growth in the face of finite resources are not easily understood by optimistic, short-term-oriented, and relatively innumerate humans (especially the political variety). The fact is that no compound growth is sustainable. If we maintain our desperate focus on growth, we will run out of everything and crash. We must substitute qualitative growth for quantitative growth. But Mrs. Market is helping, and right now she is sending us the Mother of all price signals. The prices of all important commodities except oil declined for 100 years until 2002, by an average of 70%. From 2002 until now, this entire decline was erased by a bigger price surge than occurred during World War II. Statistically, most commodities are now so far away from their former downward trend that it makes it very probable that the old trend has changed – that there is in fact a Paradigm Shift – perhaps the most important economic event since the Industrial Revolution. Climate change is associated with weather instability, but the last year was exceptionally bad. Near term it will surely get less bad. Excellent long-term investment opportunities in resources and resource efficiency are compromised by the high chance of an improvement in weather next year and by the possibility that China may stumble. From now on, price pressure and shortages of resources will be a permanent feature of our lives. This will increasingly slow down the growth rate of the developed and developing world and put a severe burden on poor countries. We all need to develop serious resource plans, particularly energy policies. There is little time to waste.
GMO 季报 2011 年 4 月《该醒醒了:资源充裕、价格下跌的日子一去不返》杰里米·格兰瑟姆 引言
我写这篇关于资源限制的文章(这是我第二篇,篇幅也长得多),目的是说服关注长期投资的股东改变整个思考框架:要认识到我们现在生活在一个不同的、更受制约的世界里,原材料价格将持续上涨,短缺将成为常态。(之前我曾承诺,一旦有了新数据就会向各位更新。经过大量艰苦工作,现在终于可以首次全面展示其中一些数据了。)
GMO QUARTERLY LETTER April 2011 Time to Wake Up: Days of Abundant Resources and Falling Prices Are Over Forever Jeremy Grantham Introduction The purpose of this, my second (and much longer) piece on resource limitations, is to persuade investors with an interest in the long term to change their whole frame of reference: to recognize that we now live in a different, more constrained, world in which prices of raw materials will rise and shortages will be common. (Previously, I had promised to update you when we had new data. Well, after a lot of grinding, this is our first comprehensive look at some of this data.)
来自发展中国家(尤其是中国)的加速需求,已导致资源价格结构发生了前所未有的转变:经历了一百多年甚至更长时间的价格下跌后,如今它们正在上涨,而在过去 8 年间,这一上涨令人瞩目地逆转了过去百年下跌所造成的影响!从统计上看,价格涨幅之大也极不寻常,使得旧趋势几乎不可能继续维持。如果我是对的,那么我们现在正进入一个时期——无论我们是否愿意,终将不得不遵循卡特总统的建议,制定深思熟虑的能源政策,并放弃过去对资源那种无忧无虑、漫不经心的态度。我们行动得越快,付出的代价就越低。为了实现孙辈生活方式的哪怕一点点改善,政治领袖们都需要拿出更具思考性的行为,而每个人都必须表现出更多克制。快速增长并非我们与生俱来的神圣权利,从数学上讲,它在长期内甚至是不可能的。我们的目标应当是让所有人都摆脱赤贫,即使这需要一定程度的收入再分配。由于我们已远远超越了可持续水平,最大的挑战将在于重新设计生活方式,在数量上降低需求水平的同时,强调生活质量。更低的人口数量将有所帮助。作为开端,我提供图 1:世界人口增长曲线。标记 X 是马尔萨斯发表其标志性著作的时间点,标记 Y 则是我的出生年份。自那以来,人口出现了何等惊人的激增!这种复利式增长在资源有限的情况下显然无法持续。在此过程中,你必然会遭遇一场范式转变。而种种迹象也越来越表明,这就是那个转折点!
Accelerated demand from developing countries, especially China, has caused an unprecedented shift in the price structure of resources: after 100 hundred years or more of price declines, they are now rising, and in the last 8 years have undone, remarkably, the effects of the last 100-year decline! Statistically, also, the level of price rises makes it extremely unlikely that the old trend is still in place. If I am right, we are now entering a period in which, like it or not, we must finally follow President Carter’s advice to develop a thoughtful energy policy and give up our carefree and careless ways with resources. The quicker we do this, the lower the cost will be. Any improvement at all in lifestyle for our grandchildren will take much more thoughtful behavior from political leaders and more restraint from everyone. Rapid growth is not ours by divine right; it is not even mathematically possible over a sustained period. Our goal should be to get everyone out of abject poverty, even if it necessitates some income redistribution. Because we have way overstepped sustainable levels, the greatest challenge will be in redesigning lifestyles to emphasize quality of life while quantitatively reducing our demand levels. A lower population would help. Just to start you off, I offer Exhibit 1: the world’s population growth. X marks the spot where Malthus wrote his defining work. Y marks my entry into the world. What a surge in population has occurred since then! Such compound growth cannot continue with finite resources. Along the way, you are certain to have a paradigm shift. And, increasingly, it looks like this is it!
马尔萨斯与碳氢化合物
马尔萨斯在 1798 年的著作精准描述了人类的过去——我们这个物种数百万年的整个发展历程。在大约过去 15 万年里,我们一直生活在食物供应的极限边缘。雨水充足的年份,食物丰饶,出生率也高;几年艰难时光,人口就会大幅缩减。事实上,我们这个物种很可能至少一次、甚至多次濒临灭绝。马尔萨斯注意到了人口与食物供应之间的这种紧密关联,他还发现,我们像大多数其他哺乳动物一样,被赋予(或者说诅咒)了极为过剩的繁殖能力。在印度部分地区,竹子大约每隔 30 年开花一次,会产生巨量蛋白质,而老鼠的种群——在这方面甚至比我们更受眷顾——显然会激增到正常数量的许多倍;随后,当竹子的蛋白质馈赠耗尽时,老鼠的种群再次崩溃,但在此之前,它们会表现出巨大的求生意志,反映在对邻近村庄一切可食之物的掠夺上。碳氢化合物正在对我们做的事情与此非常相似。在一个极短的时间窗口内,大约 250 年(讽刺的是,它恰好从 1800 年开始,让马尔萨斯基于过去的预测显得荒谬地悲观),直到 2050 年左右,碳氢化合物部分消除了人口快速增长、财富积累和科学进步的障碍。在这个窗口期内,世界人口将从 10 亿飙升至至少 80 亿,甚至可能达到 110 亿,而发达国家的人均收入已经增长了大约一百倍(从每年 400 美元增至 4 万美元)。大致如此。
Malthus and Hydrocarbons Malthus’ writing in 1798 was accurate in describing the past – the whole multi-million year development of our species. For the past 150,000 years or so, our species has lived, pushed up to the very limits of the available food supply. A good rainy season, and food is plentiful and births are plentiful. A few tough years, and the population shrinks way back. It seems likely, in fact, that our species came close to extinction at least once and perhaps several times. This complete link between population and food supply was noted by Malthus, who also noticed that we have been blessed, or cursed, like most other mammals, with a hugely redundant ability to breed. When bamboo blooms in parts of India every 30 years or so, it produces a huge increase in protein, and the rat population – even more blessed than we in this respect – apparently explodes to many times its normal population; then as the bamboo’s protein bounty is exhausted, the rat population implodes again, but not before exhibiting a great determination to stay alive, reflected in the pillaging of the neighboring villages of everything edible. What hydrocarbons are doing to us is very similar. For a small window of time, about 250 years (starting, ironically, just in time to make Malthus’ predictions based on the past look ridiculously pessimistic), from 1800 to, say, 2050, hydrocarbons partially removed the barriers to rapid population growth, wealth, and scientific progress. World population will have shot up from 1 to at least 8, and possibly 11, billion in this window, and the average per capita income in developed countries has already increased perhaps a hundred-fold (from $400 a year to $40,000). Give or take.

如我三年前所写,这一增长进程随时间推移不断加速。领头的英国用了在当时闻所未闻的 100 年,将其财富翻了一番。起步较晚的德国用了 80 年,以此类推,直到 20 世纪的日本在 20 年内实现翻番,紧随其后的是韩国,用了 15 年。但日本当时只有 8000 万人口,韩国只有 2000 万。从最近说起——比如 21 年前日本增长浪潮结束时——中国(如今拥有近 13 亿人口)开始每 10 年甚至更短时间就翻一番。印度很快也加入了这场浪潮。如今,仅这两个国家就有 25 亿人——是马尔萨斯时代全球总人口的 2.5 倍——去年它们的 GDP 增速超过 8%。这一趋势,再加上较小发展中国家广泛提速的增长,已经改变了世界。其中最为深远的影响莫过于对资源的需求。如果我的这个假设正确,那么当我们的有限资源开始走下坡时,依赖碳氢化合物的人口将远高于可持续水平,即远远超出地球的承载力。如何应对这种不可持续的需求激增,不仅是“石油峰值”,而是“一切资源峰值”,将是我们物种面临的最大挑战。但无论我们是否能够应对这一挑战,在这条路上,有限资源和资源效率领域都会诞生巨额财富,参与其中将是明智之举。

Britain, leading the charge, doubled her wealth in a then unheard of 100 years. Germany, starting later, did it in 80 years, and so on until Japan in the 20th century doubled in 20 years, followed by South Korea in 15. But Japan had only 80 million people and South Korea 20 million back then. Starting quite recently, say, as the Japanese surge ended 21 years ago, China, with nearly 1.3 billion people today, started to double every 10 years, or even less. India was soon to join the charge and now, officially, 2.5 billion people in just these two countries – 2.5 times the planet’s entire population in Malthus’ time – have been growing their GDP at a level last year of over 8%. This, together with a broad-based acceleration of growth in smaller, developing countries has changed the world. In no way is this effect more profound than on the demand for resources. If I am right in this assumption, then when our finite resources are on their downward slope, the hydrocarbon-fed population will be left far above its sustainable level; that is, far beyond the Earth’s carrying capacity. How we deal with this unsustainable surge in demand and not just “peak oil,” but “peak everything,” is going to be the greatest challenge facing our species. But whether we rise to the occasion or not, there will be some great fortunes made along the way in finite resources and resource efficiency, and it would be sensible to participate.
有限的资源 稍作思考,这些有限的资源是多么了不起!从某种意义上说,碳氢化合物本可以不存在。在一个稍有差异的星球上,这种太阳能量令人难以置信的密集储存、以及经过数百万年压缩腐烂的动植物遗骸,都不会存在。至于金属,许多金属在整个宇宙中都很稀缺,它们之所以成为我们的遗产,仅仅是因为其他大质量恒星的死亡阵痛。星际采矿之所以出现在如此多的科幻小说中,绝非无缘无故。这些是真正罕见的元素,极其宝贵,除黄金等少数例外,它们被我们消耗殆尽,其残余物或多或少被毫无用处地散落各处。如果我们足够幸运还能保持完好,那么下个世纪翻捡垃圾坑无疑将成为一道风景线。而如果我们对它们的使用改变了环境契合的方式,从而将这份遗产变成一种诅咒,那将是多么讽刺。经过数百万年的试错,环境已经找到了一个稳定而令人钦佩的平衡,而我们正在剧烈地扰乱它。
Finite Resources Take a minute to reflect on how remarkable these finite resources are! In a sense, hydrocarbons did not have to exist. On a trivially different planet, this incredible, dense store of the sun’s energy and millions of years’ worth of compressed, decayed vegetable and animal matter would not exist. And as for metals, many are scarce throughout the universe and became our inheritance only through the death throes of other large stars. Intergalactic mining does not appear in so many science fiction novels for nothing. These are truly rare elements, ultimately precious, which, with a few exceptions like gold, are used up by us and their remnants scattered more or less uselessly around. Scavenging refuse pits will no doubt be a feature of the next century if we are lucky enough to still be in one piece. And what an irony if we turned this inheritance into a curse by having our use of it alter the way the environment fits together. After millions of years of trial and error, it had found a stable and admirable balance, which we are dramatically disturbing.
GMO 2 季度信函——《该醒醒了》——2011 年 4 月 背景铺垫:一个没有碳氢化合物的世界
要意识到在找到可替代的可再生技术之前就开始耗尽廉价碳氢化合物将多么危险,我们只需想象一个没有它们的世界。在 17 和 18 世纪的荷兰和英国,已有少数地区拥有可观的财富、商业成功和技术进步。西欧刚刚开始修建运河,这是运输生产力的一次巨大飞跃,这些运河持续使用了 200 年,有些至今仍在服役。牛顿、莱布尼茨和许多其他人的工作,以过去的标准衡量,让科学突飞猛进。在世界对碳氢化合物产生很大依赖之前,弗洛伦斯·南丁格尔——顺便说一句,她也是位伟大的统计学家——说服当局相信清洁卫生可以拯救生命。快速帆船很快成为蒸汽时代之前的技术典范。像英国这样的大国能够调动惊人的资源,在全球各地同时进行多场海外战争(并非全胜!),而且这一切都不依赖碳氢化合物,甚至不使用蒸汽动力。不过,当时的世界人口只有现在的七分之一,预期寿命也只有三十多岁。但那个世界有一个近乎致命的缺陷:木材即将短缺。木材是生产钢铁所需木炭的原料,而钢铁又是改进机械的关键——这是进步的核心。(现在估计,中国全部的木材产量甚至不足以生产其当前钢铁产量的 5%!)荷兰和英国的财富尤其依赖高大笔直桅杆的木制帆船,以至于能否获取合适的木材成了外交政策和海外战争中的重大议题。更重要的是,在西欧,木材几乎也是唯一的能源来源。毫不意外,人口和财富的增长给天然森林带来了难以承受的压力,这些森林在西欧——尤其是英格兰——迅速消失,在北非和近东则早已遭到严重破坏。木材的可用性很可能是当时世界经济增长的最大制约因素;在一个没有碳氢化合物的世界里,地球将急速奔向几乎无树的状态。科学依赖于碳氢化合物所支撑的财富和盈余,其发展速度会慢得多,可能只有实际进度的三分之一。因此,从 1800 年到现在,科学可能只推进到了 1870 年的水平,而即便到了那时,医学的进步可能已经超过了我们养活不断增长的人口的能力。有一点几乎是确定的:在那样一个世界里,我们要么能培养出纪律,将自身发展控制在能够维持和保护好木材供应的范围之内,要么最终会重蹈复活节岛的覆辙——砍光最后一棵树,然后先是眼睁睁看着生活质量下降,接着人口崩溃。考虑到我们在使用稀缺资源时目前缺乏自律的表现,在另一个平行宇宙里,我不认为我们能等到什么好结果。
GMO 2 Quarterly Letter – Time to Wake Up – April 2011 Setting the Scene: A World Without Hydrocarbons To realize how threatening it would be to start to run out of cheap hydrocarbons before we have a renewable replacement technology, we have only to imagine a world without them. In 17th and 18th century Holland and Britain, there were small pockets of considerable wealth, commercial success, and technological progress. Western Europe was just beginning to build canals, a huge step forward in transportation productivity that would last 200 years and leave some canals that are still in use today. With Newton, Leibniz, and many others, science, by past standards, was leaping forward. Before the world came to owe much to hydrocarbons, Florence Nightingale – a great statistician, by the way – convinced the establishment that cleanliness would save lives. Clipper ships were soon models of pre-steam technology. A great power like Britain could muster the amazing resources to engage in multiple foreign wars around the globe (not quite winning all of them!), and all without hydrocarbons or even steam power. Population worldwide, though, was one-seventh of today’s population, and life expectancy was in the thirties. But there was a near fatal flaw in that world: a looming lack of wood. It was necessary for producing the charcoal used in making steel, which in turn was critical to improving machinery – a key to progress. (It is now estimated that all of China’s wood production could not even produce 5% of its current steel output!) The wealth of Holland and Britain in particular depended on wooden sailing ships with tall, straight masts to the extent that access to suitable wood was a major item in foreign policy and foreign wars. Even more important, wood was also pretty much the sole producer of energy in Western Europe. Not surprisingly, a growing population and growing wealth put intolerable strains on the natural forests, which were quickly disappearing in Western Europe, especially in England, and had already been decimated in North Africa and the Near East. Wood availability was probably the most limiting factor on economic growth in the world and, in a hydrocarbonless world, the planet would have hurtled to a nearly treeless state. Science, which depended on the wealth and the surpluses that hydrocarbons permitted, would have proceeded at a much slower speed, perhaps as little as a third of its actual progress. Thus, from 1800 until today science might have advanced to only 1870 levels, and, even then, advances in medicine might have exceeded our ability to feed the growing population. And one thing is nearly certain: in such a world, we would either have developed the discipline to stay within our ability to grow and protect our tree supply, or we would eventually have pulled an Easter Island, cutting down the last trees and then watching, first, our quality of life decline and then, eventually, our population implode. Given our current inability to show discipline in the use of scarce resources, I would not have held my breath waiting for a good outcome in that alternative universe.
但在真实世界里,我们确实依赖碳氢化合物和其他有限资源,而当今的福祉、技术和人口规模在很大程度上都仰仗于此。这些资源缓慢枯竭的过程就已经足够痛苦;若突然耗尽且毫无准备,那将是灾难性的。
But in the real world, we do have hydrocarbons and other finite resources, and most of our current welfare, technology, and population size depends on that fact. Slowly running out of these resources will be painful enough. Running out abruptly and being ill-prepared would be disastrous.
重大范式转变:从价格下跌说起……
大宗商品定价的历史对我们人类的经济进步一直极为有益:总体而言,整个上个世纪,大宗商品价格持续稳步下跌。我们构建了一个等权指数,涵盖最重要的 33 种大宗商品。该指数并非旨在展示它们在经济中的重要性,而仅仅是为了反映重要大宗商品作为一类的平均价格走势。图 2 所示的指数始于 110 年前,呈持续下行趋势,看似完全无视了这些资源在本质上的有限性。经通胀调整后,至 2002 年的低点,平均价格每年下跌 1.2%。请想象一下,这 102 年间 1.2% 的复合下跌,为我们带来的财富和福祉增长有多么巨大。尽管我们挖的矿坑越来越深,开采的矿石品位越来越差,尽管我们总是优先使用最好的土地和一切最佳资源,但实际价格仍平均下跌了超过 70%。不可否认的报酬递减法则被技术进步所克服——这堪称对人类创造力和聪明才智的真实见证。
The Great Paradigm Shift: from Declining Prices… The history of pricing for commodities has been an incredibly helpful one for the economic progress of our species: in general, prices have declined steadily for all of the last century. We have created an equal-weighted index of the most important 33 commodities. This is not designed to show their importance to the economy, but simply to show the average price trend of important commodities as a class. The index shown in Exhibit 2 starts 110 years ago and trends steadily downward, in apparent defiance of the ultimately limited nature of these resources. The average price falls by 1.2% a year after inflation adjustment to its low point in 2002. Just imagine what this 102-year decline of 1.2% compounded has done to our increased wealth and well-being. Despite digging deeper holes to mine lower grade ores, and despite using the best land first, and the best of everything else for that matter, the prices fell by an average of over 70% in real terms. The undeniable law of diminishing returns was overcome by technological progress – a real testimonial to human inventiveness and ingenuity.
但价格下跌并非自然法则。它只是反映出,在这一特定时期,在我们特定的供需平衡下,每年约 2.0% 的边际成本增长被每年 3.2% 的更大生产力增长所抵消。但这不过是一次历史偶然。边际增长率本可能上升——
But the decline in price was not a natural law. It simply reflected that in this particular period, with our particular balance of supply and demand, the increasing marginal cost of, say, 2.0% a year was overcome by even larger increases in annual productivity of 3.2%. But this was just a historical accident.

资料来源:GMO,截至 2011 年 2 月 28 日 更快的增长;生产率原本可能上升得更慢。在这些关系中,我们一直很幸运。最重要的是,需求本可以上升得更快,而正是在这里,最近,我们的运气开始耗尽了。…… 走向价格上涨 就在我们至少开始看到石油峰值以及部分资源质量快速下降的可能性时,来自中国、印度及其他发展中国家的需求爆炸性增长出现了。这里,与过去的关键区别在于,如前所述,中国和印度的体量之大,以及发展中国家整体的史无前例的增长速度。这种增长加速相当突然地影响了全球需求。在 1995 年之前,(令人瞩目的是,以今天的眼光来看)发展中国家与发达国家的总体增长没有差别。而在过去几年里,发展中国家的增长率与发达国家的比例达到了 3 比 1!
Source: GMO As of 2/28/11 faster; productivity could have risen more slowly. In those relationships we have been lucky. Above all, demand could have risen faster, and it is here, recently, that our luck has begun to run out. … to Rising Prices Just as we began to see at least the potential for peak oil and a rapid decline in the quality of some of our resources, we had the explosion of demand from China and India and the rest of the developing world. Here, the key differences from the past were, as mentioned, the sheer scale of China and India and the unprecedented growth rates of developing countries in total. This acceleration of growth affected global demand quite suddenly. Prior to 1995, there was (remarkably, seen through today’s eyes) no difference in aggregate growth between the developing world and the developed world. And, for the last several years now, growth has been 3 to 1 in their favor!
从 1900 年之后的 102 年间,几乎每一种商品——无论是金属还是农产品——都跌到了历史最低点。只有原油在 1974 年明显脱离了这一趋势,预示着后来的变化。但自 2002 年以来,我们经历了有史以来最显著的实际价格上涨,而我相信,这一现象将被载入史册。图表 2 展示了这一分水岭事件。直到 20 年前,一切都毫无意外可言——像第一次世界大战、第二次世界大战、1974 年和 1979 年两次通胀性石油危机这类重大突发事件,会引发价格普遍飙升;而战后萧条、大萧条这样的经济衰退,则会导致价格普遍暴跌。这大体上符合人们的预期,唯一不同的是,这一切都发生在一个长期下行趋势的背景下。但到了 1990 年代,事情开始变得反常。首先,在截至 2002 年的 15 年左右时间里,价格出现了显著下跌。我们该给图表加上什么样的描述呢?“1990 年代资源生产率激增”或许是一个选项。这一趋势可能受到了苏联阵营解体的推动。这是一次非常重要但相当隐蔽的变化,投资界对此几乎没有什么关注。仿佛价格下跌是上天赋予我们的权利。更重要的是,对于 2002 年至今的这轮飙升,我们又该加上什么描述呢?它的幅度远超第二次世界大战引发的上涨,好在这回没有爆发第三次世界大战。我个人的建议是:“伟大范式转变”。
The 102 years to 2002 saw almost each individual commodity – both metals and agricultural – hit all-time lows. Only oil had clearly peeled off in 1974, a precursor of things to come. But since 2002, we have the most remarkable price rise, in real terms, ever recorded, and this, I believe, will go down in the history books. Exhibit 2 shows this watershed event. Until 20 years ago, there were no surprises at all in the sense that great unexpected events like World War I, World War II, and the double inflationary oil crises of 1974 and 1979 would cause prices to generally surge; and setbacks like the post-World War I depression and the Great Depression would cause prices to generally collapse. Much as you might expect, except that it all took place around a downward trend. But in the 1990s, things started to act oddly. First, there was a remarkable decline for the 15 or so years to 2002. What description should be added to our exhibit? “The 1990’s Surge in Resource Productivity” might be one. Perhaps it was encouraged by the fall of the Soviet bloc. It was a very important but rather stealthy move, and certainly not one that was much remarked on in investment circles. It was as if lower prices were our divine right. And more to the point, what description do we GMO 4 Quarterly Letter – Time to Wake Up – April 2011 put on the surge from 2002 until now? It is far bigger than the one caused by World War II, happily without World War III. My own suggestion would be “The Great Paradigm Shift.”
这一变化的主要原因不仅是中国经济规模及其增长速度的加快,还在于其资本支出占 GDP 的比例之高令人震惊——超过 50%,这是历史上任何经济体都从未达到过的水平,而且差距悬殊。没错,印度和大多数其他新兴国家的确也起到了推波助澜的作用,但到 2009 年时,中国对某些大宗商品的吸纳比例之高,依然令人瞩目。图表 3 显示,在重要的非农产品大宗商品中,中国对全球石油的消费占比相对较小,略高于 10%,这大致与其(按购买力平价调整后的)GDP 占比相当。占比次低的是镍,为 36%。其余八种,包括水泥、煤炭和铁矿石,则都上升到约 50% 的惊人水平!在农产品大宗商品方面,数据更为多样化,总体也低一些:占全球小麦的 17%、大豆的 25%(谢天谢地有巴西!)、大米的 28%,以及生猪的 46%。这猪可真够多的!
The primary cause of this change is not just the accelerated size and growth of China, but also its astonishingly high percentage of capital spending, which is over 50% of GDP, a level never before reached by any economy in history, and by a wide margin. Yes, it was aided and abetted by India and most other emerging countries, but still it is remarkable how large a percentage of some commodities China was taking by 2009. Exhibit 3 shows that among important non-agricultural commodities, China takes a relatively small fraction of the world’s oil, using a little over 10%, which is about in line with its share of GDP (adjusted for purchasing parity). The next lowest is nickel at 36%. The other eight, including cement, coal, and iron ore, rise to around an astonishing 50%! In agricultural commodities, the numbers are more varied and generally lower: 17% of the world’s wheat, 25% of the soybeans (thank Heaven for Brazil!) 28% of the rice, and 46% of the pigs. That’s a lot of pigs!

乐观者会说,表 3 所描述的局面充其量只是暂时的,或许是太多机构涌入大宗商品市场所致。货币疯子们可能会把整波行情归因于低利率。可现在,连我都知道低利率至少在叠加道德风险时会对股票走势产生很大影响,但在短期内,股票价格不存在真实世界的检验,它们可能而且往往在心理上反复无常。但大宗商品是由严肃的专业人士生产和购买的,对他们来说,今天的价格就是生死线。真实的供需关系才是主要影响因素。

The Monetary Maniacs may ascribe the entire move to low interest rates. Now, even I know that low rates can have a large effect, at least when combined with moral hazard, on the movement of stocks, but in the short term, there is no real world check on stock prices and they can be, and often are, psychologically flakey. But commodities are made and bought by serious professionals for whom today’s price is life and death. Realistic supply and demand really is the main influence.
附录 4 显示,大多数大宗商品的价格与之前的下行趋势相比偏离到了何等程度。我们用标准差来表述这一点,但对大多数人而言——当然包括我在内——一个概率性的说法,比如“44 年一遇的事件”等等,更容易理解。GMO 对资产泡沫的延伸研究目前涵盖了 330 个完整的泡沫案例,甚至包括一些相当小的泡沫。这些泡沫出现的频率仅比完全随机世界中的预期高出 30% 左右。在一个“黑天鹅”概念变得非常流行的世界里,这相当令人意外。
Exhibit 4 shows how out of line with their previous declining trends most commodities are. We have stated this in terms of standard deviations, but for most of us, certainly including me, a probabilistic – 1-in-44-year event, etc. – is more comprehensible. GMO’s extended work on asset bubbles now covers 330 completed bubbles, including even quite minor ones. These bubbles have occurred only 30% or so more than would be expected in a perfectly random world. In a world where black swans are becoming very popular, this is quite a surprise.

Then I don’t believe the trend! The list continues: coal, copper, corn, and silver … a real cross section and all in hyper bubble territory if the old trends were still in force. And look at the whole list: twelve over 3-sigma, eleven others in 2-sigma territory (which we have always used as the definition of a bubble), four more on the cusp at 1.9, two more over 1.0, and three more up. Only four are down, three of which are insignificantly below long-term trend, and the single outlier is not even an economic good – it’s what could be called an economic “bad” – tobacco. This is an amazing picture and it is absolutely not a reflection of general investment euphoria. Global stocks are pricey but well within normal ranges, and housing is mixed. But commodities are collectively worse than equities (S&P 500) were in the U.S. in the tech bubble of 2000! If you believe that commodities are indeed on their old 100-year downward trend, then their current pricing is collectively vastly improbable. It is far more likely that for most commodities the trend has changed, just as it did for oil back in 1974, as we’ll see later.
GMO 6 季度信函——该醒醒了——2011 年 4 月 少数经济学家意识到资源的有限性,在过去曾多次提出(但特别是在 1970 年代)一种理论,认为我们的资源很快就会耗尽,价格将稳步上涨。然而,他们的理论从未得到任何早期预警信号(比如价格持续上涨)的支持,表明这种枯竭真的迫在眉睫。事实恰恰相反。价格持续下跌。这些空头对供需的估计也大错特错,因为他们不断低估了廉价供应的规模。但现在,在大宗商品年均需求又翻了一番以上、人口增长 50% 之后,价格信号反而变得嘈杂,而经济学家们却出奇地沉默。也许他们就像大牛市里过早做空的空头一样,已经失去了勇气。
GMO 6 Quarterly Letter – Time to Wake Up – April 2011 Aware of the finite nature of our resources, a handful of economists had propounded several times in the past (but back in the 1970s in particular) the theory that our resources would soon run out and prices would rise steadily. Their work, however, was never supported by any early warning indicators (read: steadily rising prices) that, in fact, this running out was imminent. Quite the reverse. Prices continued to fall. The bears’ estimates of supply and demand were also quite wrong in that they continuously underestimated cheap supplies. But now, after more than another doubling in annual demand for the average commodity and with a 50% increase in population, it is the price signals that are noisy and the economists who are strangely quiet. Perhaps they have, like premature bears in a major bull market, lost their nerve.
为什么如此波澜不惊?
Why So Little Fuss?
我认为我们正处在经济史上一个巨大的转折点之中。这可能是我称之为“碳氢革命”(而不是工业革命)所带来的人口与财富迅猛增长的终局之始。史无前例的广泛价格上涨似乎印证了这一点。三年前,我警告过大宗商品将出现“连锁”危机,这已成现实,而且还没有出现全面爆发的石油危机。然而,恐慌情绪却如此之少,甚至连分析工作都如此之少。我认为,这种悖论之所以存在,是因为人类某些不寻常的特性。
I believe that we are in the midst of one of the giant inflection points in economic history. This is likely the beginning of the end for the heroic growth spurt in population and wealth caused by what I think of as the Hydrocarbon Revolution rather than the Industrial Revolution. The unprecedented broad price rise would seem to confirm this. Three years ago I warned of “chain-linked” crises in commodities, which have come to pass, and all without a fully-fledged oil crisis. Yet there is so little panicking, so little analysis even. I think this paradox exists because of some unusual human traits.
人类的问题 作为数十万年——甚至数百万年——试错进化的产物,我们的物种在许多方面都表现出色,这也许并不令人惊讶。为了在开阔的稀树草原上生存,我们进化得跑得相当快,投掷相当准确,攀爬能力也足够。最重要的是,我们拥有出色的空间感知能力和手眼协调能力。我们常常很灵活,偶尔也很有创造力。
The Problem with Humans As a product of hundreds of thousands, if not millions, of years of trial and error, it is perhaps not surprising that our species is excellent at many things. Bred to survive on the open savannah, we can run quite fast, throw quite accurately, and climb well enough. Above all, we have excellent spatial awareness and hand/eye coordination. We are often flexible and occasionally inventive.
然而,面对现代世界,我们的装备却并不那么完善。我们似乎不太擅长处理长期议题和延迟满足。因为在人类 99% 以上的进化历程中,我们无法储存食物,全部心思都放在今年、这周能不能活下来,这并不奇怪。我们也不擅长数学。我们典型的数学技能,与我们细微精妙的语言技能相比,显得相当不发达。同样,沟通曾经关乎生死,数学则不然。你有没有像我一样,赞叹过人类在繁忙车流中驾驶时所展现出的惊人平均技能,以及——也许更重要的——极高的最低技能水平?还有哪项活动,几乎每个人都能表现得如此出色?想象一下,如果这些反映我们远古需求的驾驶技能,被我们平均的数学水平所取代,驾驶会变成什么样!
For dealing with the modern world, we are not, however, particularly well-equipped. We don’t seem to deal well with long horizon issues and deferring gratification. Because we could not store food for over 99% of our species’ career and were totally concerned with staying alive this year and this week, this is not surprising. We are also innumerate. Our typical math skills seem quite undeveloped relative to our nuanced language skills. Again, communication was life and death, math was not. Have you not admired, as I have, the incredible average skill and, perhaps more importantly, the high minimum skill shown by our species in driving through heavy traffic? At what other activity does almost everyone perform so well? Just imagine what driving would be like if those driving skills, which reflect the requirements of our distant past, were replaced by our average math skills!
我们也成为一个乐观且过度自信的物种,这在早期可能是帮助我们生存下来的特质,如今又被新兴的行为研究学者不断证实。而我们文化中的某些分支比其他分支更乐观、更过度自信。我名单上排在最前面的是美国和澳大利亚。在最近一次著名的国际测试中,¹美国学生的数学成绩排在第 28/40 位,相当糟糕,语言技能排在第 18 位,也相当平庸;但当他们在测试结束后被问及自己数学考得怎么样时,他们的自信程度却排在最前列。相反,实际数学技能排名第一的香港学生,在他们的预期上却表现得平均而谦虚。
We also became an optimistic and overconfident species, which early on were characteristics that may have helped us to survive and today are reaffirmed consistently by the new breed of research behaviorists. And some branches of our culture today are more optimistic and overconfident than others. At the top of my list would be the U.S. and Australia. In a well-known recent international test,1 U.S. students came a rather sad 28/40 in math and a very mediocre eighteenth in language skills, but when asked at the end of the test how well they had done in math, they were right at the top of the confidence list. Conversely, the Hong Kongers, in the #1 spot for actual math skills, were averagely humble in their expectations.
幸运的是,乐观似乎是未来成功的真正指标。哈佛大学 1930 年代一项著名研究发现,乐观的学生在早期生活的各个方面都更成功,甚至最终寿命也更长。乐观很可能与美国商业的成功有很大关系。例如,我们在互联网等新技术领域尝试的风险投资远比更为保守的欧洲人多得多,而且毫不意外,最终我们获得的赢家也更多。但乐观也有其负面。没有人喜欢听到坏消息,但根据我的经验,没有哪个国家比美国和澳大利亚更痛恨听到坏消息。不那么乐观的欧洲人和其他地区的人对悲观言论更持开放态度。告诉一个英国人你认为他们处于房地产泡沫中,你们能有一场讨论。告诉一个澳大利亚人,你会引发第三次世界大战。1999 年告诉一个美国人,成长型股票即将迎来一场可怕的崩盘,他很可能会告诉你,你没抓住重点,65 倍市盈率由互联网和其他炫目的技术所支撑,是合理的,而且,顺便说一句,以后别进我们大楼了。这种过度乐观也多次让我在气候变化问题上碰了一鼻子灰,那么多原本理性的人更愿意听福克斯新闻充满乐观的只言片语,也不愿听坏消息——哪怕这些坏消息明显是现实的。我见过几位才华横益的反向投资分析师,站在气候怀疑论者一边,全都因为——比方说——不愿花上十或十二个小时自己做一番严肃的分析。我在激发人们对资源问题的兴趣方面完全失败,同样让我印象深刻:这就像把报告扔进了一个黑洞。最后,在绝望中,我们挖掘了大量数据,而挖掘得越多,不幸的是,情况看起来越糟。
Fortunately, optimism appears to be a real indicator of future success. A famous Harvard study in the 1930s found that optimistic students had more success in all aspects of their early life and, eventually, they even lived longer. Optimism likely has a lot to do with America’s commercial success. For example, we attempt far more ventures in new technologies like the internet than the more conservative Europeans and, not surprisingly, end up with more of the winners. But optimism has a downside. No one likes to hear bad news, but in my experience, no one hates it as passionately as the U.S. and Australia. Less optimistic Europeans and others are more open to gloomy talk. Tell a Brit you think they’re in a housing bubble, and you’ll have a discussion. Tell an Australian, and you’ll have World War III. Tell an American in 1999 that a terrible bust in growth stocks was coming, and he was likely to have told 1 P.I.S.A. Test 2003, OECD.

Quarterly Letter – Time to Wake Up – April 2011 7 GMO you that you had missed the point, that 65 times earnings was justified by the Internet and other dazzling technology, and, by the way, please stay out of my building in the future. This excessive optimism has also been stuck up my nose several times on climate change, where so many otherwise sensible people would much prefer an optimistic sound bite from Fox News than to listen to bad news, even when clearly realistic. I have heard several brilliant contrarian financial analysts, siding with climate skeptics, all for want of, say, 10 or 12 hours of their own serious analysis. My complete lack of success in stirring up interest in our resource problems has similarly impressed me: it was like dropping reports into a black hole. Finally, in desperation, we have ground a lot of data and, the more we grind, the worse, unfortunately, it looks.
未能理解持续复利增长的不可能性
我之前简要提到人类作为一个物种在数字认知上的欠缺,现在想深入探讨其中一个方面:我们无法理解并内化复利增长的影响。这种能力缺失在很大程度上导致我们愿意忽视有限资源上需求复利增长所带来的后果。四年前,我和一群超级量化专家(其中大多数是数学博士)讨论金融与环境问题。我用了当时全球经济的增长率——连续两年 4.5% ——并指出,这是我们如今渴望达到的增长率。为了说明这种复利增长的荒谬不可持续性,我建议我们想象一下古埃及人(这个例子我在 2008 年 7 月的信里用过),他们的神祇、法老、语言和普遍文化延续了 3000 多年。假设他们最初只有 1 立方米的实物财富(为了方便计算),我问他们,如果以 4.5% 的复合增长,3000 年后他们会拥有多少实物财富。这些人是受过训练的数学家,所以我调侃他们:“来吧,猜一下。内化这个大致概念。你知道这数字会非常大。”得到的回答是:“厚达数英里,绕地球一圈”,“不,比那大得多,从这儿到月球。”确实是大数字,但没人接近正确答案。事实上,这些潜在专家中,没有一个猜对实际数字 1057 的 10 亿分之 1,这个数字大到连 10 亿个太阳系都塞不下。不信你算算。如果受过训练的数学家都错得这么离谱,普通智人又怎能有概念?答案是,他没有。于是,我继续说:“试试看,假设他们的财富或人口以 1% 的速度复利增长。”(作为对比,自马尔萨斯时代以来,英格兰的人口增长率低于 1%。)3000 年后,埃及最初的人口——比如说是 300 万——会增长 9 万亿倍!到那时连停车的地方都没有,更别提财富了。即使按 0.1% 这样低的复利增长,他们的人口或财富也会增长 20 倍,大约是实际情况的 10 倍。而 0.1% 这个增长率很可能是在几千年里可持续的最高复利增长,即便如此,有时也会打破系统。但真正的底线是:没有任何复利增长是可以持续的。然而,这个现实与我们今天的生活方式相差多远啊——我们怀着不切实际的期望水平,最重要的是,我们的领导者只是假设出乐观的结果。如今,大致说来,没有人愿意接受我们必须降低集体增长野心的这一隐含结论。我曾受邀参加一个每月讨论会,与会者非常多样化且非常聪明,在我那因时差而晕乎乎的头脑中,我慢慢意识到该轮到我发言了。最后,走投无路之下,我发表了平生第一次“所有东西都要耗尽”的长篇大论(一如既往地跑题)。没有一个人同意。他们一致认为的是:人类的心智——不像资源——是无限的,因此,智慧的骑兵总会及时赶来救援。我太累了,懒得去争辩:一个又一个玛雅文明所拥有的无限大脑,也无法阻止它们因(主要是)气候不利而崩溃。许多其他文明,尽管拥有和我们一样的大脑,也在资源滥用后要么覆灭,要么悄悄消亡。这种对人类大脑的信仰只是人类例外论,无论从我们过去的灾难、我们对地球造成的累积破坏,还是从我们现在面对那辆迅速逼近、而且相当贴心地鸣着汽笛的远距离火车时、那僵若木鸡的反应来看,都毫无根据。
Failure to Appreciate the Impossibility of Sustained Compound Growth I briefly referred to our lack of numeracy as a species, and I would like to look at one aspect of this in greater detail: our inability to understand and internalize the effects of compound growth. This incapacity has played a large role in our willingness to ignore the effects of our compounding growth in demand on limited resources. Four years ago I was talking to a group of super quants, mostly PhDs in mathematics, about finance and the environment. I used the growth rate of the global economy back then – 4.5% for two years, back to back – and I argued that it was the growth rate to which we now aspired. To point to the ludicrous unsustainability of this compound growth I suggested that we imagine the Ancient Egyptians (an example I had offered in my July 2008 Letter) whose gods, pharaohs, language, and general culture lasted for well over 3,000 years. Starting with only a cubic meter of physical possessions (to make calculations easy), I asked how much physical wealth they would have had 3,000 years later at 4.5% compounded growth. Now, these were trained mathematicians, so I teased them: “Come on, make a guess. Internalize the general idea. You know it’s a very big number.” And the answers came back: “Miles deep around the planet,” “No, it’s much bigger than that, from here to the moon.” Big quantities to be sure, but no one came close. In fact, not one of these potential experts came within one billionth of 1% of the actual number, which is approximately 1057, a number so vast that it could not be squeezed into a billion of our Solar Systems. Go on, check it. If trained mathematicians get it so wrong, how can an ordinary specimen of Homo Sapiens have a clue? Well, he doesn’t. So, I then went on. “Let’s try 1% compound growth in either their wealth or their population,” (for comparison, 1% since Malthus’ time is less than the population growth in England). In 3,000 years the original population of Egypt – let’s say 3 million – would have been multiplied 9 trillion times! There would be nowhere to park the people, let alone the wealth. Even at a lowly 0.1% compound growth, their population or wealth would have multiplied by 20 times, or about 10 times more than actually happened. And this 0.1% rate is probably the highest compound growth that could be maintained for a few thousand years, and even that rate would sometimes break the system. The bottom line really, though, is that no compound growth can be sustainable. Yet, how far this reality is from the way we live today, with our unrealistic levels of expectations and, above all, the optimistic outcomes that are simply assumed by our leaders. Now no one, in round numbers, wants to buy into the implication that we must rescale our collective growth ambitions. I was once invited to a monthly discussion held by a very diverse, very smart group, at which it slowly dawned on my jet-lagged brain that I was expected to contribute. So finally, in desperation, I gave my first-ever “running out of everything” harangue (off topic as usual). Not one solitary soul agreed. What they did agree on was that the human mind is – unlike resources – infinite and, consequently, the intellectual cavalry would always ride to the rescue. I was too tired to argue that the infinite brains present in Mayan civilization after Mayan civilization could not stop them from imploding as weather (mainly) moved against them. Many other civilizations, despite being armed with the same brains as we have, bit the dust or just faded away after the misuse of their resources. This faith in the human brain is just human exceptionalism and is not justified either by our past disasters, the accumulated damage we have done to the planet, or the frozen-in-the-headlights response we are showing right now in the face of the distant locomotive quite rapidly approaching and, thoughtfully enough, whistling loudly.
哈伯特峰值 让我们从迄今为止最重要的大宗商品——石油——开始更详细的讨论。而且,让我们从迄今为止最大的用户——美国——开始。1956 年,壳牌石油公司的地质学家金·哈伯特逐一分析了美国每一个主要油田的生产概况,并根据新发现趋势和衰减率得出结论:美国石油产量很可能在 1970 年左右达到峰值。当然,既得利益者和既得乐观情绪就是那么回事——他的生活因人身攻击而痛苦不堪;有人说他不是爱国者,说他做这些全是为了抬高自己的重要性,而且最重要的是,说他是个白痴。但他是对的:美国石油产量在 1971 年达到峰值!这典型地并没有阻止那些人身攻击。对手正确——没有比这更令人憎恨的事了。1956 年,哈伯特还预测全球峰值将在“大约 50 年”后到来,但在 1974 年欧佩克成立且油价飙升后,他说这可能会使产量曲线变得平缓,并将峰值推迟大约 10 年,即推迟到 2016 年左右。又一次,这可能是一个惊人准确的预测!
Hubbert’s Peak Let’s start a more detailed discussion of commodities on by far the most important: oil. And let’s start with by far the largest user: the U.S. In 1956, King Hubbert, a Shell oil geologist, went through the production profile of every major GMO 8 Quarterly Letter – Time to Wake Up – April 2011 U.S. oil field and concluded that, given the trend of new discoveries and the rate of run-off, U.S. oil production was likely to peak in around 1970. Of course, vested interests and vested optimism being what they are, his life was made a total misery by personal attacks – it was said that he wasn’t a patriot, that he was doing it all to enhance his own importance, and, above all, that he was an idiot. But he was right: U.S. production peaked in 1971! This, typically enough, did not stop the personal attacks. There is nothing more hateful in an opponent than his being right. In 1956, Hubbert also suggested that a global peak would be reached in “about 50 years,” but after OPEC formed in 1974 and prices jumped, he said it would probably smooth out production and extend the peak by about 10 years, or to 2016, give or take. Once again, this could be a remarkably accurate estimate!
1971 年美国石油产量达峰这一事件,对于反驳今天那些与他在 1960 年代面对的相同论点至关重要。这一次,这些论点被用来反对全球石油接近峰值的说法。当年那些论调是:技术天才、资本主义动力以及无限的工程创造力总能推迟清算日的到来。但美国在 1960 年代岂不是充满了最资本主义的精神、扬基智慧和创造力?美国不是拥有伟大的石油服务公司,而且在这里钻探的油井远比任何地方都多吗?这些都是事实。然而,1971 年产量仍然下降了,此后便缓慢且相当稳定地持续下滑。即使我们忽略了复利增长面对有限资源时内在的不可能性,当我们眼前有美国的例子时,又怎么可能认为我们人类的美德和勤奋就能阻止全球石油峰值的到来?
The U.S. peak oil event of 1971 is important in rebutting today the same arguments that he faced in the 1960s. This time, these arguments are used against the idea that global oil is nearing its peak. The arguments back then were that technological genius, capitalist drive, and infinite engineering resourcefulness would always drive back the day of reckoning. But wasn’t the U.S. in the 1960s full of the most capitalist of spirits, Yankee know-how, and resourcefulness? Didn’t the U.S. have the great oil service companies, and weren’t there far more wells drilled here than anywhere? All true. But, still, production declined in 1971 and has slowly and pretty steadily declined ever since. Even if we miss the inherent impossibility of compound growth running into finite resources, how can we possibly think that our wonderful human attributes and industriousness will prevent the arrival of global peak oil when we have the U.S. example in front of us?
表 5 显示,全球传统陆上石油实际上早在 1982 年就已达峰值,只有成本高得多的海上钻井和三次采油技术才使得产量有哪怕微小的增长,而且代价是价格大幅提高。表 6 显示,从 1983 年起,每年(除了一次库存减少)新发现的常规石油量都低于实际开采量!
Exhibit 5 shows that global traditional onshore oil, in fact, peaked long ago in 1982, and that only much more expensive offshore drilling and tertiary recovery techniques allowed for even a modest increase in output, and that at much higher prices. Exhibit 6 shows that since 1983, every year (except one draw) less new conventional oil was found than was actually pumped!

全球油价:第一次范式转变
我们目睹了 2000 年至 2003 年间大宗商品价格普遍跌至谷底。但石油是个例外,鉴于其按价值计算约占 50% 的权重,这便是一个极其重要的例外。1974 年,石油与其他商品分道扬镳,而后者仍在持续大幅下跌。正是在 1974 年,石油卡特尔——欧佩克——成立了。还有什么比围绕一种有限资源组建卡特尔更有利于快速实现范式转变的时机呢?图表 7(您可能并不陌生)是五年前我第一次恍然大悟时制作的,不久后便刊登在《纽约时报》周日版上。它显示,在长达 100 年的时间里,按今天的货币计算,石油的实际价格惊人地稳定在每桶 16 美元左右,即便其他所有商品价格都在下跌。从这个意义上说,它始终是个例外。石油的价格序列波动剧烈,考虑到供应冲击、储存困难,以及最重要的——短期需求价格弹性极低,这并不令人意外。相对于趋势而言,正常的波动幅度会超过一倍或低于一半,因此在 16 美元的趋势线附近,我们通常会预期价格飙升至 32 美元以上,或跌至 8 美元以下。画上 1 个和 2 个标准差的两条虚线,可以看出这个序列表现得中规中矩:在 100 年期间,它应该向上突破 2 西格玛线约 2.5 次,向下突破约 2.5 次(因为 2 西格玛事件预计每 44 年发生一次),而事实也大致如此。同样清楚的是,这条有条不紊的 16 美元趋势线在 1974 年,也就是欧佩克成立的那一年,陡然上升至每桶约 35 美元。而欧佩克是以一种极具敌意和侵略性的姿态开始的,这在其成员国之间造成了非同寻常的团结。石油价格围绕这一新的更高趋势线持续剧烈波动,在 1980 年达到顶峰,按今天的货币计算接近 100 美元(这在一定程度上证实了新的更高趋势),随后在 1999 年回落至 16 美元。
Source: Association for the Study of Peak Oil and Gas Global Oil Prices, the First Paradigm Shift We have seen how broad-based commodity prices declined to a trough from 2000-03. Oil however, was an exception and, given its approximate 50% weight by value, a very important exception. In 1974, it split off from other commodities, which continued to decline steeply. It was in 1974 that an oil cartel, OPEC, was formed. What better time could there be for a fast paradigm shift than during a cartel forming around a finite resource? Exhibit 7, which may be familiar to you, was developed when the penny first dropped for me five years ago, and was soon after reproduced in the Sunday New York Times. It shows that for 100 years oil had a remarkably flat real price of around $16/barrel in today’s currency, even as all other commodities declined. It was always an exception in that sense. Oil has a volatile price series, which is not surprising given supply shocks, the difficulty of storage, and, above all, the very low price elasticity of demand in the short term. Normal volatility is, relative to trend, more than a double and less than a half, so that around the $16 trend we would normally expect to see price spikes above $32 and troughs below $8. Drawing in the dotted lines of 1 and 2 standard deviations, it can be seen that the series is well behaved: it should breach the 2-sigma line about 2.5 times up and 2.5 times down in a 100-year period (because 2-sigma events should occur every 44 years), and it does pretty much just that. It is also clear that this well-behaved $16 trend line was shifted quite abruptly to around $35/barrel in 1974, the year OPEC began. And OPEC began in a very hostile and aggressive mood, resulting in unusual solidarity among its members. Oil prices remained very volatile around this new higher trend, peaking in 1980 at almost $100 in today’s currency (confirming, to some degree, the new higher trend) and falling back to $16 in 1999.
如今,回顾自 2003 年左右以来的油价序列,似乎又发生了一次范式跳跃,价格跃升至大约每桶 75 美元,又是一次翻倍。围绕这一新趋势,典型的油价波动区间将在每桶 150 美元到 37 美元之间。这个猜测是否成立,大概再过 15 到 20 年就能见分晓。我们拭目以待。不过,这项价格分析还有一个不同的支撑点,那就是成本分析。我们(至少目前)还不算是石油成本方面的专家,但就我们所能判断的结果来看,今天发现并输送大量新增石油的全部成本大约在每桶 70 到 80 美元。如果这个数字属实,那么第二次范式跳跃的可能性就几乎可以确定了。
Today, looking at the oil price series from about 2003, it seems likely that a second paradigm jump has occurred, to about $75 a barrel, another doubling. Around this new trend, a typical volatile oil range would be from over $150 to under $37. The validity of this guess will be revealed in, say, another 15 to 20 years. Stay tuned. There is, though, a different support to this price analysis, and that is cost analysis. We are not (yet, anyway) experts in oil costs, but as far as we are able to determine, the full cost of finding and delivering a major chunk of new oil today is about $70 to $80 a barrel. If true, this would make the idea of a second paradigm jump nearly certain.

范式大转变
于是,石油让我曾经坚不可摧的均值回归信念破了产。我一直承认范式转变在理论上是可能的,但我终于结结实实地碰上了一个。它带来了两件事。第一,它让我开始思考:为什么这次感觉与过去那些号称是范式转变的事件截然不同?第二,它让我睁眼看到另一个现实——未来迟早还会有其他范式转变出现。
01/31/1875 01/31/1887 01/31/1899 1/31/1911 1/31/1923 1/31/1935 1/31/1947 1/30/1959 1/29/1971 1/31/1983 1/31/1995 1/31/2007 Jan-1875 1887 1899 1911 1923 1935 1947 1959 1971 1983 1995 2007 Source: Global Financial Data, GMO As of 3/31/11 The Great Paradigm Shift So, oil caused my formerly impregnable faith in mean reversion to be broken. I had always admitted that paradigm shifts were theoretically possible, but I had finally met one nose to nose. It did two things. First, it set me to thinking about why this one felt so different to those false ones claimed in the past. Second, it opened my eyes to the probability that others would come along sooner or later.
这种范式转变的差异显而易见。所有典型的虚假范式转变都带有乐观色彩。它们往往更像是为高资产价格辩护的理由,而非严肃的论证。并且其来源通常也存疑——对金融服务业而言,持续很长时间的长期牛市(先涨过头再迅速崩盘)远比市场稳定更为有利可图。想象一下,如果美股只按 1925 年以来经通胀调整后那令人沮丧的年均 1.8% 涨幅上涨,我们还能赚多少钱?成交量会枯竭,交易也会消失,我们会因无聊而死,或者干脆换个工作。简而言之,要警惕那些向你说“像今天这样定价过高的市场其实很便宜”的经纪人或卖方“策略师”。最后,公众总体上似乎乐见现状如此,并且总是急于接受新范式的想法。而石油范式转变和“万物枯竭”论恰恰相反:它是个非常坏的消息,正如所有非常坏的消息一样,普通人和偏向看多的金融行业都真心想否认它,或者彻底忽视它。(就跟气候变化和天气不稳定的情况一样。)从这个意义上说,尽管这也是一种范式转变,却是一个经典的反向思维论点。
The differences in this paradigm shift are obvious. All of the typical phantom paradigm shifts are optimistic. They often look more like justifications for high asset prices than serious arguments. They are also usually compromised by the source. It is simply much more profitable for the financial services business to have long bull markets that overrun and then crash quite quickly than it is to have stability. Imagine how little money would be made by us if the U.S. stock market rose by its dreary 1.8% a year adjusted for inflation, its trend since 1925. Volume would dry up, as would deals, and we’d die of boredom or get a different job. In short, beware a broker or a sell side “strategist” offering arguments as to why overpriced markets like today’s are actually cheap. Finally, the public in general appears to like things the way they are and always seems eager to embrace the idea of a new paradigm. The oil paradigm shift and the “running out of everything” argument is the exact opposite: it is very bad news and, like all very bad news, ordinary mortals and the bullishly-biased financial industry seriously want to disbelieve it or completely ignore it. (Just as is the case with climate warming and weather instability.) It is in this sense a classic contrarian argument despite being a paradigm shift.
关于金属——关于寻找其他显示出范式转变迹象的资源,金属似乎是下一个最明显的起点:它们是有限的,面临持续复利增长的需求(也就是说,每年需要更多的吨数),而且使用后大多价值归零或大幅贬值,回收成本高昂。铜,在标准差列表中接近顶端,具有类似石油的趋势:资源质量下降,生产成本上升。图表 8 显示,自 1994 年以来,要获得同样一吨铜,需要多开采 50% 的矿石。
Metals On the second point – looking for other resources showing signs of a paradigm shift – the metals seemed the next most obvious place to start: they are finite, subject to demand that has been compounding (that is, more tonnage is needed each year), and, after use, are mostly worthless or severely reduced in value and expensive to recycle. Copper, near the top of the standard deviation list, has an oil-like tendency for the quality of the resource to decline and the cost of production to rise. Exhibit 8 shows that since 1994 one has to dig up an extra 50% of ore to get the same ton of copper.

These phenomena of declining ore quality and rising extraction costs are repeated across most important metals. The price of all of these metals in response to rising costs and rising demand has risen far above the old declining trend, at least past the 1-in-44-year chance. (There is a possibility, I suppose, that some of the price moves are caused by a cartel-like effect between the few large “miners.” There just might have been some deliberate delays in expansion plans, which would have resulted in extra profits, but it seems unlikely that this possible influence would have caused much of the total price rises. These very high prices are compatible with such possibilities, but I am in no position to know the truth of it.) There also might be some hoarding by users or others, but given the extent of the price moves, it is statistically certain that hoarding could not come close to being the only effect here. Once again, the obvious primary influence is increased demand from developing countries, overwhelmingly led by China; and that we are dealing with a genuine and broad-based paradigm shift.
中国消费的金属资源中,铁矿石占比最高,达到了令人难以置信的 —— 占全球消费量 47%。图表 9 显示了铁矿石价格长达 100 年的惊人下跌趋势,与许多其他大宗商品一样,铁矿石价格在 2002 年前后触及了 100 年低点。然而,仅仅 8 年之后,铁矿石价格就创下了 110 年新高!这才是我所说的范式转移!矿业显然正在脱离其轻松阶段,没有人试图掩盖这一点。矿业领域的新势力是嘉能可(即将上市,估值约 600 亿美元)。《金融时报》4 月 11 日报道,其首席执行官伊万·格拉森伯格在描述为何他的公司要在刚果和赞比亚运营时说:“我们先把澳大利亚的那些好啃的、简单的、容易的搞定了,然后又从美国下手,再去了南美……现在我们得去更偏远的地方了。”这是对一个行业正在脱离轻松阶段、步入永久性更高价格和更高风险的下降通道的绝佳描述。
The highest percentage of any metal resource that China consumes is iron ore, at a barely comprehensible 47% of world consumption. Exhibit 9 shows the spectacular 100-year-long decline in iron ore prices, which, like so many other commodities, reach their 100-year low in or around 2002. Yet, iron ore hits its 110-year high a mere 8 years later! Now that’s what I call a paradigm shift! Mining is clearly moving out of its easy phase, and no one is trying to hide it. A new power in the mining world is Glencore (soon to be listed at a value of approximately $60 billion). Its CEO, Ivan Glasenberg, was quoted in the Financial Times on April 11, describing why his firm operates in the Congo and Zambia. “We took the nice, simple, easy stuff first from Australia, we took it from the U.S., we went to South America… Now we have to go to the more remote places.” That’s a pretty good description of an industry exiting the easy phase and entering the downward slope of permanently higher prices and higher risk.
大宗商品农产品转到农业上,限制因素更加隐蔽。我们总以为自己有近乎无限的土地储备,但这是一种误导,因为一等田与三等田之间的产出差距可能相差数倍,而只有巴西,或许还有乌克兰,才真正拥有巨大的潜在增产空间。在其他地方,可用土地正在减少。——GMO 第十二季度信函《是时候清醒了——2011 年 4 月》图表 9 铁矿石价格(2011 年美元/干公吨)250 美元 200 美元 150 美元 100 美元 50 美元 0 美元 1900 年 1 月 1910 年 1920 年 1930 年 1940 年 1950 年 1960 年 1970 年 1980 年 1990 年 2000 年 2010 年 来源:全球金融数据 截至 2010 年 12 月 31 日——几个世纪以来,城镇往往建在河谷的优质农业用地上,而不是山坡或岩石地带。这并没有帮上忙。不过,过去我们在每英亩产量上取得了令人瞩目的增长,这确实帮了大忙。但遗憾的是,这些增长正在放缓。图表 10 显示,在 1960 年代末,全球生产率的平均增长率为每年 3.5%。能年复一年保持这样的增长,是何等的成就。图表 10 作物单产的 10 年平均年增长率 4.0% 3.5% 3.0% 作物单产的 10 年平均年增长率 2.5% 2.0% 1.5% 人口 10 年平均年增长率 1.0% 0.5% 0.0% 1971 年 1976 年 1981 年 1986 年 1991 年 1996 年 2001 年 2006 年 来源:联合国粮食及农业组织 截至 2009 年 12 月 31 日《季度信函——是时候清醒了——2011 年 4 月》13 GMO 生产率增长放缓丝毫不令人意外。目前的生产率增长率大约只有 1960 年代增速的三分之一。每年 1.25% 仍然是一个令人印象深刻的数字,但趋势显然在放缓,而需求并未放缓,反而还在加速。那么,过去 50 年里如此巨大的生产率增长是如何维持的?靠的是化肥使用量的更快速增长。图表 11 显示,在生产率增长率下降的同一时期,每英亩化肥施用量增长了五倍。这是一个令人痛苦的关系,因为再增加化肥的效用是有限的,而随着生产率增速放缓到 1%,它将与规模相当的人口增长相遇。日益增加的以谷物为主的肉类消费,再加上令人遗憾地将玉米用于乙醇生产(这一过程不仅剥夺了我们的食物,甚至可能不是能量正收益!),给谷物价格带来了进一步的压力。这些趋势并没有显示出多少安全边际。
Agricultural Commodities Moving on to agriculture, the limitations are more hidden. We think of ourselves as having almost unlimited land up our sleeve, but this is misleading because the gap between first-rate and third-rate land can be multiples of output, and only Brazil, and perhaps the Ukraine, have really large potential increments of output.

For centuries, cities and towns have tended to be built not on hills or rocky land, but on prime agricultural land in river valleys. This has not helped. We have, though, had impressive productivity gains per acre in the past, and this has indeed helped a lot. But, sadly, these gains are decreasing. Exhibit 10 shows that at the end of the 1960s, average gains in global productivity stood at 3.5% per year.

It is hardly surprising that the growth in productivity has declined. It runs now at about one-third of the rate of increase of the 1960s. It is, at 1.25% a year, still an impressive rate, but the trend is clearly slowing while demand has not slowed and, if anything, has been accelerating. And how was this quite massive increase in productivity over the last 50 years maintained? By the even more rapid increase in the use of fertilizer. Exhibit 11 shows that fertilizer application per acre increased five-fold in the same period that the growth rate of productivity declined. This is a painful relationship, for there is a limit to the usefulness of yet more fertilizer, and as the productivity gains slow to 1%, it bumps into a similar-sized population growth. The increasing use of grain-intensive meat consumption puts further pressure on grain prices as does the regrettable use of corn in ethanol production. (A process that not only deprives us of food, but may not even be energy-positive!) These trends do not suggest much safety margin.

Potash and potassium are mined and, like all such reserves, the best have gone first. But the most important fertilizer has been nitrogen, and here, unusually, the outlook for the U.S. really is quite good for a few decades because nitrogen is derived mainly from natural gas. This resource is, of course, finite like all of the others, but with recent discoveries, the U.S. in particular is well-placed, especially if in future decades its use for fertilizer is given precedence.
更令人不安的,是石油在农业生产和流通所有其他环节中的大量使用。在所有碳氢化合物让我们得以在发展道路上飞速奔跑、超越可持续极限的方式中,这一点最为令人不安。我们没有依靠头脑,而是靠蛮力能源来提升产量。
More disturbing by far is the heavy use of oil in all other aspects of agricultural production and distribution. Of all the ways hydrocarbons have allowed us to travel fast in development and to travel beyond our sustainable limits, this is the most disturbing. Rather than our brains, we have used brute energy to boost production.
地表和地下的水资源也日益稀缺,开始带来切实影响。就连底土也在持续流失。迟早有一天,人们必须认识到环境的极限,并且大力推广免耕法等改良技术。我们必须保护现有的资源。这确实是一场危机,亟需超越企业盈利或政治人物通常思考周期的长远规划。归根结底,关键是价格,而近期的信号已足够清晰。图表 12 展示了四种关键农产品——小麦、水稻、玉米和大豆——近年来的实际价格走势。与其他许多大宗商品不同,这四种产品目前仍远低于它们的历史高位,但从近期的低点算起,它们的价格都已经翻了一倍甚至两倍。
Water resources both above and below ground are also increasingly scarce and are beginning to bite. Even the subsoil continues to erode. Sooner or later, limitations must be realized and improved techniques such as no-till farming must be dramatically encouraged. We must protect what we have. It really is a crisis that begs for longer-term planning – longer than the typical horizons of corporate earnings or politicians. The bottom line is, as always, price, and the recent signals are clear. Exhibit 12 shows the real price movements of four critical agricultural commodities – wheat, GMO 14 Quarterly Letter – Time to Wake Up – April 2011 Exhibit 12 Real Grain Prices (2011 $/bushel) Wheat Rice $12 $20 $18 $10 $16 $8 $14 $12 $6 $10 $8 $4 $6 $2 $4 $2 $0 $0 Jan- 00 01 02 03 04 05 06 07 08 09 10 11 Jan- 00 01 02 03 04 05 06 07 08 09 10 11 Corn Soybeans $8 $18 $7 $16 $6 $14 $5 $12 $10 $4 $8 $3 $6 $2 $4 $1 $2 $0 $0 Jan-00 01 02 03 04 05 06 07 08 09 10 11 Jan- 00 01 02 03 04 05 06 07 08 09 10 11 Source: Global Financial Data As of 2/28/11 rice, corn, and soybeans – in the last few years. Unlike many other commodities, these four are still way below their distant highs, but from their recent lows they have all doubled or tripled.
多头会说,这些农产品属于传统的泡沫,由狂热和投机驱动,注定会跌回 2002 年以前的价格。但各位不妨想一想:比如小麦丰收的时候,会发生什么?只有磨坊主和面包师(实际上是拥有这些客户的粮食交易商)会来购买。哈佛大学的捐赠基金可不会提出要买 100 万吨,然后储存在哈佛校园里(尽管有传闻说,我的偶像凯恩斯勋爵曾经认真考虑过,要把英国两个月的供应量堆在国王学院礼拜堂里!)。价格由供需决定,而储存空间有限且昂贵。所有农产品还会相互影响,所以如果某一种农产品被人为抬价,处于边际的农民就会减少大豆等作物的种植,转而种更多小麦。所有农产品一起同步大幅上涨,这远远超出了投机者的能力范围。最终的证据是:农业储备处于低位——危险的低位。这个事实本身,就很难容下任何大规模囤积行为的存在。
Bulls will argue that these agricultural commodities are traditional bubbles, based on euphoria and speculation, and are destined to move back to the pre-2002 prices. But ask yourselves what happens when the wheat harvest, for example, comes in. Only the millers and bakers (actually the grain traders who have them as clients) show up to buy. Harvard’s endowment doesn’t offer to take a million tons and store it in Harvard Yard (although my hero, Lord Keynes, is famously said to have once seriously considered stacking two months’ of Britain’s supply in Kings College Chapel!). The price is set by supply and demand, and storage is limited and expensive. All of the agricultural commodities also interact, so, if one were propped up in price, farmers on the margin would cut back on, say, soybeans and grow more wheat. For all of these commodities to move up together and by so much is way beyond the capabilities of speculators. The bottom line proof is that agricultural reserves are low – dangerously low. There is little room in that fact for there to be any substantial hoarding to exist.
天气异常与价格上涨 但有一个因素,在极少数情况下,足以推动所有农产品价格同步上涨,那就是天气,尤其是干旱和洪水。我认为,过去 100 年间,天气异常从未像过去 12 个月那样极端。如果你读任何一份农产品总结,哪怕只有一段话,都会发现天气被列为价格上涨的原因之一。我讲个黑色幽默:过去 7 年里,澳大利亚东部的平均降雨量算是正常水平,但前 6 年是有记录以来最干旱的 6 年,而第 7 年却遭遇了前所未有的大洪水,水深达数英尺。这种“平均”降雨量让农业变得艰难,也让 GMO 目前的农产品投资变得困难,因为未来 12 个月的天气几乎肯定比过去 12 个月要好,甚至可能好得多。——《季度信函:该清醒了——2011 年 4 月》第 15 页,GMO
Weather Instability and Price Rises But there is one factor big enough, on rare occasions, to move all of the agricultural commodities together, and that is weather, particularly droughts and floods. I don’t think the weather instability has ever been as hostile in the last 100 years as it was in the last 12 months. If you were to read a one-paragraph summary of almost any agricultural commodity, you would see weather listed as one of the causes of the price rising. My sick joke is that Eastern Australia had average rainfall for the last seven years. The first six were the driest six years in the record books, and the seventh was feet deep in unprecedented floods. Such “average” rainfall makes farming difficult. It also makes Quarterly Letter – Time to Wake Up – April 2011 15 GMO investing in commodities difficult currently, for the weather this next 12 months is almost certain to be less bad than the last, and perhaps much less bad.
如今大宗商品投资中一种不寻常的入场风险:天气……对于农产品而言,人们普遍预期,如果天气好转,明年价格就会下跌。因为去年全球天气——至少对农业来说——是几十年来最糟糕的,所以这个预测看起来很靠谱。当然,气候变化方面的科学证据是压倒性的。气候科学家们完全认同的一点是,除了大气中二氧化碳百万分比浓度持续攀升之外,地球变暖最可靠的特征就是气候不稳定。好吧,各位,过去 12 个月简直就是一场极端不稳定的怪兽,而且几乎全都对农业不利。那些善于合理化事实的怀疑论者,对天气也毫不费力就能自圆其说——无论天气多么恶劣,单凭一年数据永远无法提供长期变化的强力证据。不幸的是,我相信我们不得不承认,极端天气将是我们共同未来的一大特征,而且概率很高。但如果去年是常态,那我们面临的麻烦远比任何人预期的都要严重得多。更可能的情况是,明年会好一些,甚至完全友善。如果真是这样,那我们被淹没的就不是雨水,而是谷物——因为每个人都在耕种每一寸能犁的土地。何乐而不为?当前的价格要么是历史最高,要么只在 2008 年有几周更高过,要么就是几十年前才见过的高位。在我看来,机构资金和投机资金并不会像之前所说的那样推高现货价格,但它们会持续推高远月期货合约的价格。传统上,农民得花钱请投机者帮他们承接一部分未来的价格风险。如今,高盛等机构把大宗商品包装成很有吸引力的投资(基于投资者应从承担风险中获得回报的老观念),以至于涌入的资金把远期曲线斜率推了上去。这不仅破坏了当初投资期货合约的根本理由,而且对于眼前这个论点至关重要的一点是,它降低了农民转移价格风险的成本,从而促使——至少是鼓励——他们种植更多,事实也正是如此。讽刺的是,机构投资反而促进了更大规模的生产,进而压低了价格!如果阳光和雨水都在正确的时间和地点降临,那么我们将迎来创纪录的产量。这对于已经严重枯竭的库存来说是件好事,但对现货价格来说却可能是一场灾难(尽管小麦可能是一个例外,因为最大种植国——中国——即将到来的收成情况看起来非常糟糕)。
The Unusual Entry Risk Today in Commodity Investing: Weather … For agricultural commodities, it is generally expected that prices will fall next year if the weather improves. Because global weather last year was, at least for farming, the worst in many decades, this seems like a good bet. The scientific evidence for climate change is, of course, overwhelming. A point of complete agreement among climate scientists is that the most dependable feature of the planet’s warming, other than the relentless increase in the parts per million of CO2 in the atmosphere, is climate instability. Well, folks, the last 12 months were a monster of instability, and almost all of it bad for farming. Skeptics who have little trouble rationalizing facts will have no trouble at all with weather, which, however dreadful, can never in one single year offer more than a very strong suggestion of long-term change. Unfortunately, I am confident that we should be resigned to a high probability that extreme weather will be a feature of our collective future. But, if last year was typical, then we really are in for far more serious trouble than anyone expected. More likely, next year will be more accommodating and, quite possibly, just plain friendly. If it is, we will drown, not in rain, but in grain, for everyone is planting every single acre they can till. And why not? The current prices are either at a record, spent just a few weeks higher in 2008, or were last higher decades ago. The institutional and speculative money does not, in my opinion, drive the spot prices higher for reasons given earlier, but they do persistently move the more distant futures contracts up. Traditionally, farmers had to bribe speculators to take some of the future price risk off of their hands. Now, Goldman Sachs and others have done such a good job of making the case for commodities as an attractive investment (on the old idea that investors were going to be paid for risk-taking), that the weight of money has pushed up the slope of the curve. This not only destroys the whole reason for investing in futures contracts in the first place, but, critically for this current argument, it lowers the cost to the farmers of laying off their price risk and thus enables, or at least encourages, them to plant more, as they have in spades. Ironically, institutional investing facilitates larger production and hence lower prices! Should both the sun shine and the rain rain at the right time and place, then we will have an absolutely record crop. This would be wonderful for the sadly reduced reserves, but potentially terrible for the spot price. (Although wheat might be an exception because the largest grower by far – China – is looking to be in very bad shape for its upcoming harvest.)
……而中国则恰恰相反。我的几位精明同事都同意吉姆·查诺斯的判断,他们认为中国的结构性失衡将导致其经济在未来 12 个月内至少有一个轮子脱落。在以 10% 的 GDP 年增长率超高速行驶时,这将是痛苦的。问题清单如下:a) 工资前所未有的上涨削弱了中国的竞争力。b) 高达 GDP 50% 的资本支出,部分是由于西方银行体系崩溃时,为让这艘船继续航行而做出的一场英勇而绝望的努力。这无法持续,而且其中很大一部分支出很可能被浪费了:不必要的机场、公路、铁路,以及无人居住的高层公寓。c) 债务水平增长过快。d) 房价已深陷泡沫区域,不良贷款数量未知,但可能庞大。爱德华·钱塞勒和吉姆·查诺斯都已对此做过更精辟、更详细的阐述。其重要意义在于,鉴于中国对如此众多大宗商品的压倒性影响力,尤其是在全球需求新增部分中中国所占的百分比,中国经济的任何轻微磕绊,都可能导致其中一些大宗商品价格大幅下跌。
… and China Quite separately, several of my smart colleagues agree with Jim Chanos that China’s structural imbalances will cause at least one wheel to come off of their economy within the next 12 months. This is painful when traveling at warp speed – 10% a year in GDP growth. The litany of problems is as follows: a) An unprecedented rise in wages has reduced China’s competitive strength. b) The remarkable 50% of GDP going into capital spending was partly the result of a heroic and desperate effort to keep the ship afloat as the Western banking system collapsed. It cannot be sustained, and much of the spending is likely to have been wasted: unnecessary airports, roads, and railroads and unoccupied high-rise apartments. c) Debt levels have grown much too fast. d) House prices are deep into bubble territory and there is an unknown, though likely large, quantity of bad loans. You have heard it all better and in more detail from both Edward Chancellor2 and Jim Chanos. The significance here is that given China’s overwhelming influence on so many commodities, especially in terms of the percentage China represents of new growth in global demand, any general economic stutter in China can mean very big declines in some of their prices.
你可以自行判断未来一年左右中国出问题的概率。按我的最低估计,概率为四分之一,而有些同事认为概率要高得多。如果中国出问题,或者天气状况比预期更好……
You can assess on your own the probabilities of a stumble in the next year or so. At the least, I would put it at 1 in 4, while some of my colleagues think the odds are much higher. If China stumbles or if the weather is better than 2 Edward Chancellor, “China's Red Flags,” GMO White Paper, March 23, 2010.
GMO 16 季度信函——《该醒醒了》——2011 年 4 月 预期的,我会把概率定在比方说 80%,那么大宗商品价格将大幅下跌。但如果两件事同时发生,它很可能会整体击垮大宗商品市场。与金融崩溃并无二致。那是一次千载难逢的机会,因为大多数市场暴跌超过 50%,有些更甚,然后强劲反弹。谦逊本应阻止我引用自己 2008 年 7 月的季度信函,那封信涵盖了第一次崩溃。“大宗商品价格短期内可能破裂(见本信函第一部分),但这只是虚晃一枪。[编者注:所引部分标题为‘崩盘!全球能力危机’,讨论的是全球金融危机后的余波。] 在未来十年,所有原材料的价格将按其真实价值定价,即它们是不可替代的。”如果天气和中国综合征同时爆发,那肯定会在三年内制造出第二次“千载难逢”的事件。2009 年初,机构投资者忙于自救,无暇过多关注大宗商品领域的第一次机会,而且无论如何,其他一切资产价格也都在下跌。未来几年里第二次大宗商品崩盘,在心理上可能也难以投入资金,因为它必然会引出常见的看多论调:“你看,一切如常。原材料充足,所以别听那些末日预言者的。”由于这个论点有广泛支持,它将难以抗拒,但应该抗拒。
GMO 16 Quarterly Letter – Time to Wake Up – April 2011 expected, a probability I would put at, say, 80%, then commodity prices will decline a lot. But if both events occur together, it will very probably break the commodity markets en masse. Not unlike the financial collapse. That was a once in a lifetime opportunity as most markets crashed by over 50%, some much more, and then roared back. Modesty should prevent me from quoting from my own July 2008 Quarterly Letter, which covered the first crash. “The prices of commodities are likely to crack short term (see first section of this letter) but this will be just a tease. [Editor’s Note: the section referred to is titled “Meltdown! The Global Competence Crisis,” which discusses the aftermath of the global financial crisis.] In the next decade, the prices of all raw materials will be priced as just what they are, irreplaceable.” If the weather and China syndromes strike together, it will surely produce the second “once in a lifetime” event in three years. Institutional investors were too preoccupied staying afloat in early 2009 to have obsessed much about the first opportunity in commodities and, in any case, everything else was also down in price. A second commodity collapse in the next few years may also be psychologically hard to invest in for it will surely bring out the usual bullish argument: “There you are, its business as usual. There are plenty of raw materials, so don’t listen to the doomsayers.” Because it will have broad backing, this argument will be hard to resist, but should be.
残余投机因素
最后,还有一部分是老式的投机行为,尤其集中在少数能够储存的商品上,比如黄金和其他按磅计价成本较高的品种。我认为,这在整体价格压力中只占很小一部分,低利率的影响也类似,但它们共同作用,也确实助推了价格的温和上涨。将这种投机放在更大的背景下分析,我们可以说:a) 商品领域的投机活动在增加,但仍属常规性;b) 这一情况叠加在影响远为重大的恶劣天气效应之上;c) 最关键的是,几乎所有商品都经历了一场深刻的范式转变,其根源是基本面因素发生了永久性变化。
Residual Speculation Finally, there is some good, old-fashioned speculation, particularly in the few commodities that can be stored, like gold and others, which are costly per pound. I believe this is a small part of the total pressure on prices, and the same goes for low interest rates, but together they have also helped push up prices a little. Putting this speculation into context, we could say that: a) we have increasing, but still routine, speculation in commodities; b) this comes on top of the much more important effects of terrible weather; and c) most important of all, we have gone through a profound paradigm shift in almost all commodities, caused by a permanent shift in the underlying fundamentals.
当今投资资源领域中的创造性张力
随着资源价格上涨,整个体系在整体福祉上蒙受损失,但世界上并非没有赢家。供应短缺的优质土地将升值,为土地所有者带来收益。农业技术进步将进一步增加土地持有资产的价值。肥料资源——钾碱和钾肥——将变得尤为珍贵。碳氢化合物储备的价值自然也会上升。总体而言,所有稀缺资源(当然包括水)的所有者或控制者都将受益。但其他所有人的处境都会变差,一个资源受限的世界,其人均富裕程度的增长速度将低于原本应有的水平,也低于过去的速度。请记住,这与沙特阿拉伯曾因政治原因减少部分石油开采时那种收入和财富的简单循环不同。那时,我们多付了几十亿美元,而他们把钱存入银行形成循环,没有造成净损失。但现在,当他们开采完最后一批最便宜的每桶 5 美元原油,我们用来自饱受困扰的加拿大油砂、每桶 120 美元的石油来替代时,这其中的成本差额就是一笔无谓损失。国内生产总值(GDP)核算可以将其粉饰得很好看,它当然也创造了更多就业岗位,但就像几千人用茶匙挖一个洞一样,与原本的廉价石油相比,它增加了就业,却没带来任何增量价值。
The Creative Tension in Investing in Resources Today As resource prices rise, the entire system loses in overall well-being, but the world is not without winners. Good land, in short supply, will rise in price, to the benefit of land owners. Technological progress in agriculture will add to the value of land holdings. Fertilizer resources – potash and potassium – will become particularly precious. Hydrocarbon reserves will, of course, also increase in value. In general, owners or controllers of all limited resources, certainly including water, will benefit. But everyone else will be worse off, and a constrained-resource world will increase in affluence per capita more slowly than it would have otherwise, and more slowly than in the past. Remember, this is not simply a recycling of income and wealth as it was when Saudi Arabia stopped some of its pumping for political reasons. Then, we paid a few extra billion and they put money in the bank for recycling. There was no net loss. But now when they pump the last of the cheapest $5/barrel of oil and we replace it with a $120/barrel from tortured Canadian Tar Sands, the cost differential is a deadweight loss. GDP accounting can make it look fine, and it certainly creates more jobs but, like a few thousand men digging a hole with teaspoons, it adds jobs but no incremental value compared to the original cheap oil.
今天的投资者该如何应对这种极佳长期前景与极高短期风险之间的创造性紧张关系?令人沮丧却又无比准确的答案是:极其艰难。对我个人而言,这正是一个绝佳时机,可以实践我新近专精的“遗憾最小化”。例如,我的基金会正在“地下资源”和资源效率领域建立小仓位(大约是我最终目标的四分之一)。鉴于过去四年我对资源有限性这一理念的信心日益增强,如果大宗商品持续上涨、永不回落,而我却一点都没持有,那我真该一头撞到巴士底下去。如果价格继续飙升,那么我的小仓位将是一剂慰藉,我会转而关注那些定价更合理的“被落下的”大宗商品。反之,更可能的情况是,如果价格大幅下跌——也许跌得很惨烈——那我就会咬紧牙关,将持仓增加到原来的三倍或四倍,并打算永远持有。所以,事情就是如此。
How does an investor today handle the creative tension between brilliant long-term prospects and very high short-term risks? The frustrating but very accurate answer is: with great difficulty. For me personally it will be a great time to practice my new specialty of regret minimization. My foundation, for example, is taking a small position (say, one-quarter of my eventual target) in “stuff in the ground” and resource efficiency. Given my growing confidence in the idea of resource limitation over the last four years, if commodities were to keep going up, never to fall back, and I owned none of them, then I would have to throw myself under a bus. If prices continue to run away, then my small position will be a solace and I would then try to focus on the more reasonably priced – “left behind” – commodities. If on the other hand, more likely, they come down a lot, perhaps a lot lot, then I will grit my teeth and triple or quadruple my stake and look to own them forever. So, that’s the story.
美国的地位……
The Position of the U.S….
美国当然有很好的条件来应对这些制约。首先,它一开始就拥有丰厚的财富,无论是人均财富还是人均收入都很高,而且在资源方面也很充足,尤其是从长远来看最有价值的两种资源:丰富的农业用地和相当不错的供水系统。美国在碳氢化合物方面也很有禀赋。它大量的石油和天然气储量,在日益提高的水力压裂和水平钻井技术的支撑下,看起来可能会出人意料地具有韧性。而且,无论按什么标准衡量,美国的煤炭储量都非常巨大。所有其他国家要是也能这样就好了。其次,我们是所有发达国家中最浪费、最挥霍的,这个事实悖论性地变成了一个巨大优势。我们美国人可以节省几十亿美元的资源,最终反而会感觉更好,就像一个成功采用新饮食方式的肥胖者一样。
The U.S. is, of course, very well-positioned to deal with the constraints. First, it starts rich, both in wealth and income per capita, and also in resources, particularly the two that in the long run will turn out to be the most precious: great Quarterly Letter – Time to Wake Up – April 2011 17 GMO agricultural land and a pretty good water supply. The U.S. is also well-endowed with hydrocarbons. Its substantial oil and gas reserves look likely to prove unexpectedly resilient, buoyed by improving skills at fracking and lateral drilling. And, by any standard, U.S. coal reserves are very large. All other countries should be so lucky. Second, we are the most profligate or wasteful developed country and this fact, paradoxically, becomes a great advantage. We in the U.S. can save resources by the billions of dollars and actually end up feeling better for it in the end, like someone suffering from obesity who succeeds with a new diet.
劳动年龄人口增长放缓降低了所有发达国家的 GDP 增长。资源限制的加码则进一步拉低了这一增速。如果未来 20 年美国 GDP 能增长 2%,我认为我们的表现就已经相当不错了。降到 1.5% 我不会感到惊讶,那也不是什么灾难。过去 28 年里,我们以每年 3.0% 的速度提高了 GDP,而能源消耗仅增加了 0.9%。也就是说,在没有一套像样的能源政策、并且存在像汽车和住宅这样效率低下的领域的情况下,我们仍以每年 2.1% 的速度提高了能源效率。这表明,如果 GDP 增长率降至 2%,即便我们不进一步努力,能源需求的增量也可能微乎其微,甚至为零。此外,如果我们在未来 20 年内将与欧洲和日本的能源效率差距缩小一半,那么我们的能源需求甚至可能以每年 1.5% 的速度下降。考虑到美国到处都有唾手可得的果实,这是可以实现的。
The slowing growth in working age population has reduced the GDP growth for all developed countries. Adding resource limitations is further reducing it. If our GDP in the U.S. grew 2% for the next 20 years, I think we would be doing very well. Dropping to 1.5% would not surprise me, nor would it be a disaster. In the past 28 years, we have increased our GDP by 3.0% per year with only a 0.9% increase in energy required. That is, we increased our energy efficiency by 2.1% without a decent energy policy and despite some very inefficient pockets like autos and residential housing. This would suggest that at a reduced 2% GDP growth rate, we might expect little or no incremental demand for energy, even without an improved effort. If in addition we halved our deficit in energy efficiency compared with Europe and Japan in the next 20 years, then our energy requirements might drop at 1.5% a year. Given the plentiful availability of low-hanging fruit in the U.S., this is achievable.
……至于其他国家
其他国家就不会那么幸运了。几乎所有国家都会面临更低的增长,但资源丰富的国家将因贸易条件持续向其有利方向变动而获得相对优势。不那么明显的是,那些能源效率特别高的国家也会受益。例如,如果日本每单位能源能创造出中国两倍以上的 GDP,那么在其他条件相同的情况下,随着油价上涨,贸易条件将对日本有利。排在名单末尾的,是那些资源匮乏且效率低下的穷国,它们已经将高达 50% 的收入用于购买大宗商品“必需品”,它们将遭受苦难。具有讽刺意味的是,它们消耗的资源最少,却受苦最深,这恐怕不会减轻它们的痛苦。有限的资源创造了一种赢输格局,完全不同于我们在全球贸易中习以为常的共赢局面。从理论上讲,随着中国的增长,我们所有人都能通过全球贸易受益。但在资源有限的情况下,它们增长得越快、变得越富(尤其是它们吃的肉越多、谷物越少),大宗商品价格就涨得越高,对穷国以及每个国家内部的相对贫困者造成的挤压也就越大。这是一个令人沮丧的话题。只要说一句就够了:如果我们想避免加剧的饥荒和国际动荡,我们需要全球范围内的智慧和慷慨,其规模要前所未有。
… as for the Rest Other countries will not be so lucky. Almost all will suffer lower growth, but resource-rich countries will have a relative benefit as the terms of trade continue to move in their favor. Less obviously, those countries that are particularly energy efficient will also benefit. If the Japanese, for example, can produce over twice the GDP per unit of energy than the Chinese, then, other things being equal, the terms of trade will move in their favor as oil prices rise. At the bottom of the list, poor countries with few resources and little efficiency, which already use up to 50% of their income on the commodity “necessities,” will suffer. The irony that they suffered the most having used up the least will probably not make their misery less. Limited resources create a win-lose proposition quite unlike the win-win we are accustomed to in global trade. Theoretically, we all gain through global trade as China grows. But with limited resources, the faster they grow and the richer they get (and, particularly, the more meat rather than grain that they eat), the more commodity prices rise and the greater the squeeze on the poorer countries and the relatively poor in every country. It’s a gloomy topic. Suffice it to say that if we mean to avoid increased starvation and international instability, we will need global ingenuity and generosity on a scale hitherto unheard of.
结论
美国以及其他所有国家都需要一个更长期的资源规划,尤其是在能源方面,而且我们现在就需要!(关于市场和投资建议的短期观点将很快发布。)
