史上头一遭,中央银行(最关键的是美联储)正在印制足够的货币,来弥补信贷收缩,以此作为去杠杆进程的解药。理论上,央行可以通过把信贷收缩的实体接入印钞机,让它们抽取的金额恰好抵消信贷收缩所需的数额,从而制造出任何它们想要的名义 GDP 增速。这么做不仅会拉低利率,还会增加货币供应量,让市面上有更多的货币和信贷去购买商品和服务——比如,美联储买入私营部门原本不得不买的信贷工具(如机构债券),就给私营部门腾出了更多的钱去花在名义 GDP 上。虽然理论上说得通,但从来没有哪个例子能证明这一招奏效过,或者说做到现在这个规模。像疫情一样,去杠杆进程极少出现,所以可供回顾的案例不多;而在我们仅有的那些案例里,这副解药从没下过这么大的剂量。

For the first time in history central banks (most importantly the Fed) are producing enough money to make up for contracting credit as an antidote to the D-process. Theoretically, central banks can create whatever levels of nominal GDP growth that they want to create by plugging credit contracting entities into the money machine so that the amount of money that they draw equals the amount of money they need to offset the credit contraction, which not only has the effect of lowering interest rates but also increases the money supply so that there is more money and credit in existence to go for the purchases of goods and services—e.g., the Fed buying credit instruments (e.g., agency paper) that the private sector would otherwise have had to buy leaves the private sector with more money to spend on nominal GDP. While this is theoretically true, there are no good examples of this being done well or to the same extent that it is now being done. Like pandemics, D-processes come along very infrequently, so we don’t have many to look back on and, in those that we have, this antidote was never administered in this dosage.

具体来说,在 1971 年之前的去杠杆进程里,货币供应增长受制于金本位和固定汇率,这一招根本没法用;而当货币与黄金及其他货币的挂钩被打破后,反应又和人们假设的那种“从未有过这种挂钩”的情形不同——也就是说,有理由认为,当货币增速加快打破了这些挂钩后,名义 GDP 增长中会有更大的份额流向通胀和资本外逃,而不是像在没有这种挂钩时那样。同样,20 世纪 80 年代拉美新兴国家的去杠杆进程——货币供应增长就是这么用的——增加的货币供应不成比例地流向了通胀和资本外逃,比世界最重要的储备货币国家可能出现的情况更严重,尤其是因为全球有大量以该货币计价的债务。日本去杠杆进程里用增加的货币供应来弥补信贷收缩,是最接近的类比案例,但也明显不同,因为:一、剂量更小;二、货币用来买了什么不一样;三、那次去杠杆发生在全球经济增长的背景下。所以,观察这场实验性重剂量的货币刺激会产生什么效果,实在令人兴奋。

Specifically, in D-processes that occurred before 1971, when money supply growth was limited by ties to gold and by fixed foreign exchange rates, this could not happen and, when these links with gold and other currencies were broken, reactions were different than one would assume that they might be with these links previously not existing—i.e., it is reasonable to assume that a greater share of nominal GDP growth would go to inflation and capital flight when increased money growth breaks these links than when there are no such links. Similarly, in the D-processes of Latin American emerging countries in the 1980’s—where money supply growth was used in this way—the increased money supply growth went disproportionately into inflation and capital flight, more so than it might in the world’s most important reserve currency country, especially since the world has a lot of debt denominated in it. The increased money supply that was used to make up for contracting credit in the Japanese D-process was the most analogous example, but it too was significantly different because of a) the smaller dosages, b) what the money was used to buy and c) the fact that this D-process occurred in a growing world economy. So, it is very exciting to observe the effects of this experimental heavy dosage of money.

根据我们构建的货币、信贷增长与经济增长之间关联的模型,颇值得怀疑美联储能否通过以下方式让名义 GDP 按它设定的目标增长:一、适量购买金融资产;二、为政府购买商品和服务提供融资。接着有两个问题——一、名义 GDP 增长中,多大份额会转化为实际 GDP 增长,多大份额会变成通胀;二、经济看起来会跟去杠杆进程开始前一样,还是会不一样?如果不一样,又会是什么样子?

Based on our model of the linkages between money and credit growth and economic growth, there is much doubt that the Fed can cause nominal GDP to grow by about the amounts it targets via the Fed a) buying financial assets in the appropriate quantities and b) financing the government to buy goods and services in appropriate quantities. Then there are two questions—1) what share of this nominal GDP growth will go into real GDP growth and what share will go into inflation, and 2) will the economy look similar to what it was before the D-process began or will it look different, and if it will look different, what will it look like.

关于第一个问题,只要货币增长抵消了信贷收缩,就不会直接引发通胀,但在边际上会压低美元(尤其是往后看),而这可能在日后变成通胀压力(当货币走弱和/或信贷增长导致人们更多购买实物资产和抗通胀资产时)。

Re #1, to the extent money growth negates credit contraction, it won’t be directly inflationary, but it will be bearish for the dollar on the margin (especially down the road) and this can be inflationary down the road (when currency weakness and/or credit growth leads to more purchases of real goods and inflation hedge assets).

关于第二个问题,经济会和泡沫破裂前大不一样。美联储会给有生存能力的企业提供流动性,让它们更正常地运转,但同时也会让更多没有生存能力的实体(比如两房、保险公司、银行等)苟延残喘,制造出多得多的“僵尸企业”。考虑到众多庞大实体财务状况糟糕透顶,如果美联储给它们供钱(比如现在美联储几乎是机构债券的唯一买家,尽管这些机构已经严重资不抵债,仍然维持它们运转而不是让它们重整旗鼓),我们基本可以断定会出现大量僵尸企业,经济里政府的分量会大得多(说白了,就是大为国有化)。

Re #2, the economy will look very different than it looked like before the bubble burst. While the Fed will provide liquidity to viable companies that will allow them to operate more normally, it will also keep more non-viable entities (e.g., the GSEs, insurance companies, banks, etc.) alive making many more “zombie companies”. Given the terrible financial conditions of numerous enormous entities, if the Fed provides them with money (e.g., the way the Fed is now virtually the only buyer of agency paper, though these agencies are severely insolvent, keeping them kept operating rather than being made viable), we can be pretty confident that we will have many zombie companies and an economy in which the government is a much bigger player (i.e., essentially much more socialized).

在我们看来,这就是现代去杠杆进程可能的样子,也最有可能就是美国经济未来的走向。

In our opinion, that’s what modern day D-processes are likely to look like and that is most likely what the U.S. economy will look like.

供你参考,下图显示了 1920 年以来货币和债务的变化。

For your reference, the chart below shows changes in money and changes in debt going back to 1920.

下一张图显示的是 M0/GDP,也是从 1920 年开始,可以看出这一次的增速快了多少。

The next chart shows M0/GDP, also going back to 1920, and shows how much faster the increase has been this time around.

但在展望未来之前,咱们先回头看看已经发生了什么。

But before we look ahead, let’s look back on what happened.

资本市场、经济与政府之间的相互作用和领先滞后关系

The Interactions and Lead/Lag Relationships Between the Capital Markets, the Economy and the Government

资本市场(股市和债市)、经济与政府之间存在着一种相对合乎逻辑的互动,每一方都在按其自身特质和所处环境行事,所以各方既在对其他方做出反应,又在引发其他方的反应,由此造就了我们正在目睹的这一连串事件。我们试图通过理解这三股力量、它们可能的行动以及这些行动的效果来走在市场前面,理想情况是比实际进展领先约六个月。为了把这个模板用简单的话讲清楚,我在下面把它勾勒了出来。

There is a relatively logical interaction that is going on between the capital markets (stocks and bond markets), the economy and the government in which each is operating in a manner that’s relatively understandable given what they’re like and given what their circumstances are, so each is both reacting to and causing reactions in the others, thus creating the sequence of events that we are seeing. We try to stay ahead of the markets by understanding these three forces, their likely actions and the effects of these actions, ideally staying about six months ahead actual developments. To convey this template in simple terms, we sketched it out below.

为了让你了解最新情况,下表列出了截至当前的时间线要点。

To bring you up to date, the table below shows the highlights of the timeline leading up to the present.

虽然上一张图强调的这种动态由来已久,但我们的时间线从 2005 年之前说起。债务、偿债负担和金融资产的价值相对收入、净资产和货币稳步上升。这发生在全球范围内,尤其是成熟发达国家,它们与新兴国家(最重要的是中国)之间积累了巨大的失衡。然后,在 2005 年到 2007 年间,大多数人疯了——也就是说,出现了一场典型的狂热,人们用极高的杠杆以极高的价格购买资产。发生这种情况的原因我们已经详细阐述过,就不重复来烦你了。

While the dynamic highlighted in the previous chart has gone on forever, start our timeline prior to 2005. Debt, debt service and the values of financial assets rose steadily relative to incomes, net worth’s and money. This happened globally, but especially in the mature developed countries with enormous imbalances built up with emerging countries, most importantly China. Then, in 2005 to 2007, most people went crazy—i.e., there was a classic mania in which assets were bought at extremely high prices with extremely high leverage. This occurred for reasons that we have described at length and won’t bore you with by repeating.

2007 年 7 月,泡沫以去杠杆进程中的经典方式破裂了(比如 1929 年的大萧条波及全球,1990 年的日本)——现金流跟不上偿债负担,资产价值相对债务水平下降,信贷收缩吞噬了货币。

In July 2007, the bubbles burst in the classic ways they burst in D-processes (e.g., in 1929 in the Great Depression globally and in 1990 in Japan)—with cash flows not keeping up with debt service obligations, with asset values falling relative to debt levels and with contracting credit devouring money.

坦白说,从 2005 年到最近,在市场上下注比现在容易得多,因为:一、2005-2007 年间风险溢价几乎不存在(价格非常高),同时风险(比如用微不足道的现金流做超高杠杆)也非常高;二、从 2007 年年中到最近,投资者和政府都认为发生的事难以置信,所以投资者低估了它,政府应对不足。现在,投资者正在对糟糕的经济/金融前景打折扣,政府则在强力应对。

Frankly, from 2005 until recently, placing winning bets in the markets was a lot easier than it is now because a) in 2005-2007 risk premiums were virtually non-existent (prices were very high) at the same time as risks (e.g., hyper-leveraging puny cash flows) were very high, and b) from mid-2007 until recently, investors and the government considered what happened implausible, so investors under-discounted it and the government under-reacted to it. Now, investors are discounting a bad economic/financial outlook and the government is forcefully responding.

说到投资者对糟糕经济/金融前景打折扣,就拿股市和商业地产市场来说。在大萧条时期,它们通常下跌约 75%-85%。自 2007 年 7 月以来,它们已经下跌了约 50%,所以,即使假设我们会经历一场典型的大萧条(这是一个合理的悲观情形),大部分跌幅(约三分之二)已经发生了。

Regarding investors discounting a bad economic/financial outlook, take the stock and commercial real estate markets for example. In depressions, they have typically fallen by about 75%-85%. Since July 2007, they fell by about 50%, so, even if one were to assume that we will have a typical depression (which is a reasonable worst case scenario), most of the decline (about 2/3rds) has already occurred.

说到政府强力应对,表格显示了美国政府的购买和担保规模(占全部债务的三分之二!),后面那张表格则显示了全球范围内这些购买和担保的规模。

Regarding the government reacting forcibly, the table shows the amounts of U.S. government purchases and guarantees (2/3rds of all debt!) and the table after it shows the sizes of these purchases and guarantees around the world.

所以,在 2005-07 年间,不难看出要出一场大事故。这场事故从 2007 年年中开始,贯穿 2008 年。就像一场车祸,伤员被紧急送进医院急诊室,为了保命,被打了一针大剂量兴奋剂,靠美联储上了生命维持系统。总体而言,事故发生时财政部和国会毫无作为,因为起初它们对问题的察觉非常迟钝,应对起来又慢又没效果。但美联储,虽然最初在酿成事故中犯了最重要的错误(没有适当管控信贷),从事故发生时(尤其是雷曼兄弟和 AIG 崩盘的那个周末)到现在,反应一直非常迅速。

So, in 2005-07 it was fairly easy to see that there was going to be a terrible accident. This accident began in mid-2007 and continued through 2008. It was like an automobile crash in which the bodies were rushed into the emergency ward of a hospital and, to be kept alive, were shot with huge dosages of a stimulant and put on life support by the Fed. By and large the Treasury and Congress were ineffective when the accident occurred because they were initially very slow to catch on to the problems and very slow and ineffective in responding to the problems. But the Fed, which originally made the most important mistakes in causing the accident (by not properly controlling credit), was very responsive from when the accident happened (particularly into the weekend that Lehman Brothers and AIG crashed) until now.

现在越来越明显,很多病人已经稳定下来,生命体征有所改善。这是好事。但指望经济恢复正常,就跟指望一个受了创伤性伤害、还在靠生命维持系统吊命、还没有做完检查看看有哪些持久损伤的病人恢复正常一样傻。尤其因为我们知道前方还有重大冲击——比如,已经发生的事和负面连锁效应之间有很大的滞后。举例来说,最糟糕的信贷问题还在后面——它们肯定会非常严重,对实体经济的影响有多大,对资本市场影响多大,目前无法精确预知。

It is now becoming clear that many of the patients have been stabilized and there is some improvement in their vital signs. This is great. But it would be as silly to expect the economy to return to normalcy as it would be to expect a patient that has suffered traumatic damage, is still on life support and has not yet gone through the tests to see what forms of sustained damage exist, to return to normal. This is especially true because we know that there will be major shocks ahead—e.g., we know that there is a big lag between what has happened and the negative ripple effects. For example, the worst of the credit problems lie ahead—they will certainly be very large and their effects on the real economy and the capital markets can not be precisely known.

生命体征的改善

The Improved Vital Signs

在我们看来,改善体现在以下几个方面:

To us, the improvements appear as follows:

在收益率曲线的短端,尤其是在政府积极介入的那些市场,利差几乎完全恢复正常了,但正常的信贷增长尚未恢复。见下图。

On the short end of the yield curve, particularly in those markets where governments have been active, spreads have almost totally normalized, but normal credit growth has not yet resumed. See the following charts.

在收益率曲线的长端,虽然利差从极高水平有所回落,但相对过去仍然极高(也就是说,肯定还没正常化),私营部门信贷增长依然停滞。

On the long end of the yield curve, while spreads have declined some from their very high levels, they remain extremely high in relation to the past (i.e., they certainly have not normalized) and private credit growth remains stagnant.

过去几周经济活动趋于稳定,但经济短期波动很大,所以说“绿芽”一定会带来持续增长就太傻了。下图按同比口径展示了这一改善。

Economic activity has stabilized over the past few weeks, but the economy is very volatile on a short term basis, so it would be silly to say that the “green-shoots” are sure to lead to sustained growth. The following chart puts this improvement in perspective on a year-over-year basis.

尽管如前述,我们相信美联储能够通过以扩大货币增长来替代收缩的信贷增长,从而实现其想要的任何名义 GDP 增长水平,并且这将最终伴随着美元贬值,尤其是相对于人民币的贬值。尽管时机不确定,但美国(刺激经济、抵御通缩)和中国(更有效地管理其外汇储备及其经济状况)双方的利益都已转向支持这一举措。过去(即中国不在乎其储备价值,因为规模尚小,且向强劲的美国经济出口并积累大量美元储蓄是合理之时),固定汇率是有意义的;而现在(即其储蓄规模庞大,因而所持资产的表现变得重要,且美国出口市场低迷之时),让美国获得其长期寻求的人民币升值、将资产持有多元化至更具吸引力的替代品,并构建更加以内需为导向的经济,则是合理的。

Still, as mentioned before, we believe that the Fed can produce essentially whatever level of nominal GDP growth it wants via replacing contracting credit growth with increased money growth, and that this will eventually be accompanied by a devaluation of the dollar, especially against China’s currency. Though the timing is uncertain, the interests of both the United States (to stimulate its economy and negate deflation) and of China (to more effectively manage its reserves and its economic conditions) have changed in favor of this move. While in the past (i.e., when China did not care about the value of its reserves because they were small and when exporting to the strong U.S. economy and building up a large savings in U.S. debt made sense) a fixed exchange rate made sense, now (i.e., when the value of its savings is large so the performance of what it owns is important and when the U.S. market to sell exports into is depressed), it makes sense to give the U.S. the currency appreciation that it has long sought, to diversify its asset holdings into more attractive alternatives and to build a more domestically oriented economy.

再加上猪流感,“愿你生活在有趣的时代”这句中国的诅咒便有了特殊含义。

Add to this mix the swine flu and the Chinese curse “May you live in interesting times” takes on special meaning.

日本零售销售与就业状况

Japan Retail Sales & Employment Conditions

日本 3 月份零售销售收缩 1.1%,同比下降 3.9%。过去六个月需求数据开始更显著地恶化,但仍比过去十五年的历次低谷时期温和。鉴于外部需求和生产数据如此糟糕,内需状况很可能会继续大幅恶化。出口下降约 45%,生产下降超过三分之一。这种下降正日益传导至劳动力市场,进而应传导至收入和支出。

Japanese retail sales contracted 1.1% in March and are down 3.9% compared to a year ago. The demand numbers have started to deteriorate more significantly in the last six months, but it is still milder than at prior times in the last fifteen years. Given how bad the external demand and production numbers are, the domestic demand story is likely to continue to get a lot worse. Exports are down about 45%, production is down by over a third. This drop is increasingly flowing to labor markets, and in turn, should flow to incomes and spending.

尽管日本失业率较其周期性低点上升不足 1%(相比之下美国上升超过 4%),但日本企业面临更大的成本削减压力。区别在于,这种成本削减是通过减少工作时间和降低工资来实现的。结果,日本家庭实际收入的降幅比美国家庭更大。这应会在不久的将来转化为零售销售的疲软。下面我们分别以短期和长期视角展示日本的零售销售。第一张图显示月度变化(年化)及三个月平均值。第二张显示零售销售的长期年度变化。

While the Japanese unemployment rate has risen less than 1% from its cyclical lows (compared to more than 4% in the U.S.), companies in Japan have a greater pressure to reduce costs. The difference is that this cost cutting is happening through fewer hours’ worked and lower wages. As a result, Japanese households have actually experienced a greater drop in income than households in the US. This should translate into weaker retail sales in the near future. Below we show Japanese retail sales both in a short-term and long-term perspective. The first chart shows monthly changes (annualized) and the three-month average. The second shows a longer-term yearly change in retail sales.

考虑到极其疲弱的环境,日本消费者支出其实还算不错。在美国,零售销售往往领先于国内经济状况,因为企业通常根据国内消费者需求的波动来增减生产。日本并非如此,因为外部需求的波动要大得多,因此对生产的驱动作用也大得多。结果,这种传导往往方向相反且关联度不那么紧密,出口驱动的制造业增长带来日本家庭收入的增加,并最终带来零售支出的增长。尽管日本工业生产和出口的降幅均为近期历次收缩的三倍左右,消费者信心处于历史低点,零售销售却表现出韧性。下图展示了美国和日本工业生产、零售销售和出口之间的关系。

Japanese consumer spending is actually not that bad given the extremely weak conditions. In the US, retail sales tend to lead domestic conditions as businesses generally increase or decrease production in response to swings in domestic consumer demand. This has not been the case in Japan, as swings in external demand have been much greater and therefore much more of a driver of production. As a result, the linkage tends to work in the opposite direction and is not as tight, with increases in export-driven manufacturing leading to higher incomes for Japanese households and ultimately increases in retail spending. With Japanese industrial production and exports both down about three times more than in any recent contraction, and with consumer confidence at an all-time low, retail sales have actually been resilient. The charts below show the relationship between industrial production, retail sales, and exports for the US and Japan.

国内生产的崩溃尚未在日本导致大量失业,尤其是相对于其他状况不那么严重的发达国家的失业情况而言。这一差异主要归因于日本更严格的劳动法规,使企业难以解雇工人。下图展示了日本失业率的水平及变化。很容易看出,日本的失业率历来比美国和欧洲的周期性波动更小。

The collapse in domestic production has not yet led to significant job losses in Japan, especially relative to the job losses in other developed countries where conditions are less severe. This difference is mostly due to stricter labor laws in Japan which make it difficult for Japanese businesses to fire workers. The charts below show both the level and change of the unemployment rate in Japan. It is easy to see that the unemployment rate in Japan has historically had smaller cyclical swings than those occurring in the US and even Europe.

因此,总体失业率在一定程度上描绘了日本劳动力状况的误导性图景。日本企业开工率远低于产能,收入下降速度快于企业削减成本的速度,这给利润率带来压力。企业通常通过消除过剩产能来应对这种情况,而解雇员工是最快、最有效的方式之一。日本企业则通过减少工作时间来降低劳动力成本。下图第一张展示了日本工人总工作时间与美国工人总工作时间的对比。日本总体失业率上升幅度远低于美国,但整个经济体的总工作时间却以同样的速度在下降。

For this reason, the headline unemployment rate provides a somewhat misleading picture of labor conditions in Japan. Businesses in Japan are operating way below capacity, putting pressure on profit margins as revenues continue to fall quicker than companies can cut costs. Typically businesses react to these circumstances by eliminating excess capacity, and firing employees is one of the quickest and most effective ways to do this. Japanese businesses lower labor costs by lowering hours worked instead. The first chart below shows the total hours worked by Japanese workers compared to the total hours worked by American workers. While Japanese headline unemployment has risen far less than that in the US, the number of hours worked across the economy is falling at the same pace.

除工作时间减少外,日本工人再次经历显著的工资名义通缩,导致家庭收入同比降幅达 5%,而美国收入基本持平。

In addition to working fewer hours, Japanese workers are also once again experiencing significant nominal wage deflation, causing household incomes to fall at a pace of 5% YoY whereas incomes in the US have essentially been flat.

日本的需求数据近几个月开始以更显著的速度收缩。鉴于外部需求收缩、生产下降和收入减少,需求的下降远未结束。虽然收入下降向收入的传导在失业数据中并不十分明显,但在工作时间和薪酬的减少中却显而易见。相比其他发达国家,日本收入降幅更为极端,削减成本的压力也更大。这将持续以显著方式传导至内需。

Japanese demand numbers have started to contract at a more significant pace in recent months. Given the contraction in external demand, the drop in production, and the reductions in incomes, the decline in demand is far from over. While the translation of lower revenues to incomes is not very evident in the unemployment numbers, it is evident in lower hours worked and compensation. Even more than other developed countries, the drop in revenues has been extreme and there is even more pressure to cut costs. This will continue to flow through to domestic demand in a significant way.
