思考的时间到了
Time for Thinking
新冠病毒疫情暴发后的头几周、头几个月,经济活动随之停摆,经济与卫生领域的变化速度令人目不暇接。我写备忘录的速度也跟上了这个节奏:头六周每周一篇,18 周内总共写了十篇。在那样一个快节奏的开端之后,我已经一个多月没有发布备忘录了——这看起来间隔挺长,但要知道近年来常态是每季度才写一篇,也就不觉得久了。
过去一两个月,事态发展的节奏确实慢了下来,慢到我们大多数人都觉得日子千篇一律。工作和休闲都困在同一处;工作日和周末没什么两样;度假的念头几乎变得毫无意义:能去哪儿,又能做什么?我想到一个缩写 SSDD,说得文雅一点就是“天天如此,换汤不换药”。
但节奏放缓也给了人更多沉思的空间,对于当下的处境,我琢磨出了一些想法。
In the early weeks and months of the novel coronavirus pandemic and the related shutdown of the economy, the pace of economic and health developments was frenetic. My memo writing followed suit: one a week for the first six weeks, and a total of ten over 18 weeks. After starting off at that rapid clip, I haven’t issued a memo in more than a month – which might seem like a long interval until you realize the norm in recent years has been only one per quarter. The pace of events has certainly slowed over the last month or two, to the point where most of us are struck by the sameness of our days. We stay in one place for both work and leisure; weekdays aren’t very different from weekends; and the idea of vacation seems almost irrelevant: where would we go and what would we do? My acronym of choice is SSDD, the family-friendly translation of which is “same stuff, different day.” But the slower pace of developments allows for more rumination, and I’ve come up with some thoughts about our present circumstances.
健康危机
本月初,我为一位主权财富基金客户准备了一份演示文稿。他们原本预计的年度论坛是我日历上最后一趟海外行程,但当然,我改成了通过视频会议参加。我在演示文稿的开头用了这样一个比喻:
为应对特别严重的疾病,医生有时不得不采取极端手段来挽救患者生命:他们会诱导患者进入昏迷状态,以便施用猛烈的治疗手段,维持生命支持,治疗疾病,再把患者带回清醒状态。
面对新冠疫情——本世纪最严重的流行病之一——政策制定者同样被迫采取孤注一掷的措施。疫情爆发后,流行病学家告诉我们,病毒会呈指数级传播,可能夺走数百万人的生命。
在没有疫苗的情况下,控制疫情的唯一办法是防止已感染者将病毒传给他人。为此,当局认为有必要让患者进入昏迷状态。于是,经济被按下暂停键,以尽量减少人际接触。商店、餐馆、学校、宗教场所、娱乐和体育场馆被勒令关闭,旅行受到限制,人们被告知尽量居家办公。
众所周知,美国经济基本被冻结,自 3 月 21 日以来已有 5400 万美国人申请失业救济,第二季度国内生产总值按年率计算萎缩 32.9%,是 70 年有季度记录以来最大季度跌幅的三倍。(请参阅
The Health Crisis Earlier this month, I prepared a presentation for one of our sovereign-wealth-fund clients. Their annual forum had been expected to entail the last bit of foreign travel still on my calendar, but of course I participated by video conference instead. I started my PowerPoint presentation with the following metaphor: To deal with particularly serious diseases, doctors sometimes have to take extreme action to save the patient: they induce a coma to permit the administration of harsh remedies, maintain life support, treat the disease, and bring the patient back to consciousness. In the case of Covid-19, one of the worst pandemics of the last century, policymakers were similarly required to take desperate measures. Upon the eruption of the disease, epidemiologists told us it would spread exponentially, possibly killing millions. In the absence of a vaccine, the only way to deal with the outbreak was to prevent those who had contracted the disease from spreading it to others. In order to do so, the authorities decided it was necessary to put the patient into a coma. Thus the economy was shut down to minimize interpersonal contact. Stores, restaurants, schools, places of worship, and entertainment and sports venues were ordered closed, travel was restricted, and people were told to work from home whenever possible. As we all know, the U.S. economy was largely frozen, causing 54 million Americans to file for unemployment benefits since March 21 and second-quarter GDP to shrink by an annualized 32.9%, three times the greatest quarterly decline in the 70 years of recorded quarterly history.

(本备忘录结尾附有后记,我在其中讨论所报告的 32.9% 下降幅度的重要意义。)
昏迷的病人——经济——需要生命支持,美联储和财政部提供了支持。他们带着数万亿美元紧急赶到,以维持病人的生命:向个人和家庭发放款项;向受困行业提供补助;发放一般商业贷款和税收减免;向小企业提供贷款;向各州、医院和退伍军人护理提供援助;并为货币市场基金和商业票据提供担保。这些有时被描述为刺激计划,但这是一个误称:它们是支持性支付,旨在替代原本会在整个经济中流通的现金。
在经济昏迷并依靠生命支持之际,当选官员着手实施治疗。在没有疫苗的情况下,治疗形式是检测以识别患病者,追踪以确定与他们接触过的人;隔离和社交距离使他们与他人分开;戴口罩以防止无症状患者感染健康人。
当新增病例、住院人数和死亡人数下降,并且考虑到允许经济活动恢复的可取性,负责人员转向使病人复苏。经济在 5 月开始重新开放,受到接近零的基准利率和美联储提供充足流动性的支持,初步反应是积极的。零售额在 5 月上升了 17.7%(此前在 3 月和 4 月下降了 22.3%),失业率从怀疑接近 20% 的峰值降至 6 月的 11.1%。案子结了。
the end of this memo for postscript in which I discuss the significance of that reported 32.9% decline.) The comatose patient – the economy – required life-support, and the Fed and Treasury supplied it. They rushed in with trillions of dollars to keep the patient alive: payments to individuals and households; grants to distressed industries; general business loans and tax relief; loans to small businesses; aid to states, hospitals and veterans’ care; and guarantees for money market funds and commercial paper. These are sometimes described as stimulus programs, but that’s a misnomer: they were support payments designed to replace cash that normally would have circulated throughout the economy. With the economy comatose and on life support, elected officials proceeded to administer the cure. In the absence of a vaccine, this was designed to take the form of testing to identify those who had the disease and tracing to identify those with whom they’d come into contact; quarantining and social distancing to keep them separate from others; and masking to prevent the asymptomatic sick from infecting the healthy. When the number of new cases, hospitalizations and deaths declined, and in view of the desirability of allowing economic activity to resume, those in charge turned to resuscitating the patient. The economy began to reopen in May, supported by a near-zero base interest rate and the Fed’s provision of abundant liquidity, and the initial response was positive. Retail sales moved up 17.7% in May (after a 22.3% decline in March/April), and the unemployment rate fell to 11.1% in June, from a peak suspected to have been near 20%. Case closed.
未能修复问题
要是事情真这么简单就好了。不幸的是,在某些情况下,重新开放是在新增病例数尚未下降到足以控制住新冠病毒传播之前就进行的,而那些早期幸免于难的地区的人们表现得漫不经心,使得疾病在他们所在地区重新站稳了脚跟。借用丘吉尔的话(他可能也是从马基雅维利那里借来的),管理经济和企业的人常说“千万不要浪费一场好危机”。但在新冠疫情的案例中,美国恰恰就这么浪费了。
亚洲和欧洲的国家最先暴发疫情,但她们迅速采取了严厉措施——有人称之为铁腕手段——包括强制隔离和对违规者处以罚款。她们成功控制了疫情。不幸的是,一系列因素结合在一起,削弱了美国所采取的行动,使得疫情再度抬头:

Failure to Fix It If only it was that simple. Unfortunately, in some instances the reopening took place before the number of new cases had declined enough for the spread of Covid-19 to be brought under control, and people in areas that had been spared in the early days acted cavalierly, allowing the disease to regain a foothold in their regions. Borrowing from Churchill (who probably borrowed it from Machiavelli), people who regulate economies and manage businesses say “never let a good crisis go to waste.” But in the case of Covid-19, the U.S. did just that. The nations of Asia and Europe had the earliest outbreaks, but they took swift and stern action – some say Draconian – including enforcing isolation and fining violators. But they got the disease under control. Unfortunately, a number of elements combined to weaken the actions taken in the U.S. and permit a resurgence of the disease: • • • •
全国范围内缺乏统一政策来规范停摆、社交距离、佩戴口罩和重新开放。
对卫生专业人士和科学家建议的支持不足。
年轻人的鲁莽,他们被早期统计数据误导,以为自己有免疫力。
医学人类学家兼历史学家玛莎·L·林肯指出,这是“民族傲慢和对美国例外论的迷信”。正如某位民选官员在 3 月 11 日所说,“病毒没有机会战胜我们。”
The absence of uniform national policies on shutdowns, social distancing, masking and reopening. Inadequate support for the recommendations of health professionals and scientists. The foolhardiness of youth, who were misled by early statistics into believing they were immune. “National hubris and belief in American exceptionalism,” according to Martha L. Lincoln, a medical anthropologist and historian. As one of our elected leaders stated on March 11, “The virus will not have a chance against us.”

把戴口罩和保持社交距离变成党派之争,让人怀疑病毒是场骗局,防护规定是对个人自由的侵犯。
重开经济与减少感染之间的艰难抉择,也被政治化了。目前新增病例增长最快的州,大多是优先选择前者而忽视后者的州。
The turning of masking and social distancing into partisan issues, raising suspicion that the virus is a hoax and protective rules an infringement of personal freedom. The politicization of the difficult choice between reopening the economy and minimizing infections. The states currently seeing the greatest increases in new cases are mostly ones that emphasized the former over the latter.
显然,社会重新开放、人们开始聚集时,病毒尚未被控制在可控水平,导致其再度抬头。而在某些地区为抗疫而封锁、另一些地区却不封锁,当人们可自由往来其间时,这种做法相当危险。如今,接触者追踪——在那些成功控制住新冠病毒传播的国家,这是防疫武器库中的一件重器——据称在美国已因感染人数之巨而形同虚设。于是,我们看到的不是人们期望的感染、昏迷、生命支持、治疗、康复、复苏这一进程,而是感染、昏迷、生命支持、治疗、复苏的进程。治愈环节缺失了。由于美国大部分地区在疫情完全受控之前就重新开放,早期的封锁成效付诸东流,当前每日新增病例数远超 3 月和 4 月。RockCreek 集团 7 月 27 日的报告说得好:
在新冠仍在多地蔓延扩散之时重新开放,美国可能两头不讨好:一方面遭遇急剧衰退,将以企业倒闭、破产和生活被打乱留下创伤;另一方面,疾病持续肆虐,在没有有效治疗手段和疫苗的情况下,即使不是不可能,也将难以根除。
因此,7 月 30 日《纽约时报》报道如下:
“经济的前进道路极不确定,很大程度上将取决于我们能否成功控制住病毒,”[美联储主席杰罗姆]鲍威尔在美联储两天会议结束后的新闻发布会上表示,并指出自 6 月下旬以来感染人数激增,“复苏的步伐似乎已经放缓。”
鲍威尔先生表示,决策者需要更多数据才能对经济回落的范围做出明确结论,但他指出,借记卡和信用卡支出正在放缓,劳动力市场指标显示近期就业增长可能正在减弱。(强调为本译所加)
Clearly, society reopened and people began to congregate before the virus was reduced to controllable levels, allowing it to reemerge. And shutting down to fight the disease in some locations but not others was dangerous when people can travel freely among them. Now contact tracing – a very important weapon in the arsenal of the countries that got the spread of Covid-19 under control – is said to have been rendered useless in the U.S. by the sheer number of people who’ve been infected. So rather than the desired progression of infection, coma, life support, treatment, cure and resuscitation, we’ve had a progression of infection, coma, life support, treatment and resuscitation. The cure is missing. Because much of America reopened before the disease was brought fully under control, the early lockdowns went to waste, and the current number of daily new cases far exceeds that of March and April. RockCreek Group’s July 27 report put it well: By reopening when COVID-19 was still spreading and pervasive in many places, the US may have gotten the worst of both worlds: a sharp recession, which will leave scars in terms of business closures, bankruptcies and disrupted lives, and continued disease, that will be difficult if not impossible to eradicate, in the absence of effective treatments and vaccines. Thus, on July 30, The New York Times reported as follows: “The path forward for the economy is extraordinarily uncertain and will depend in large part on our success in keeping the virus in check,” [Fed Chairman Jerome] Powell said at a news conference following the Fed’s two-day meeting, noting that infections have surged since late June and the “pace of recovery looks like it has slowed.” Mr. Powell said policymakers needed more data before drawing firm conclusions about the scope of the pullback, but he noted that debit and credit card spending were slowing and labor market indicators suggested that recent job gains might be weakening.

非周期
近来我常被问到两个问题:“我们正处于什么周期?”以及“我们处在周期的哪个阶段?”我的主要回答是,过去五个月的发展本质上是非周期性的,因此不能用通常的周期分析来套用。正常的周期始于经济和市场的低点;克服心理和资本市场的逆风;受益于经济积聚动能;见证企业业绩超出预期;被乐观的企业决策放大;又被日益正面的投资者情绪强化;从而推动股票和其他风险资产价格上涨,直到它们……
Not a Cycle Two of the questions I get most often these days are, “What kind of cycle are we in?” and “Where do we stand in it?” My main response is that the developments of the last five months are non-cyclical in nature, and thus not subject to the usual cycle analysis. The normal cycle starts off from an economic and market low; overcomes psychological and capital market headwinds; benefits from gathering strength in the economy; witnesses corporate results that exceed expectations; is amplified by optimistic corporate decisions; is reinforced by increasingly positive investor sentiment; and thus fosters rising prices for stocks and other risk assets until they

顶部过度时则反之(下行时亦然)。但在当前情况下,一个温和的复苏——以合理增长、现实预期、无企业过度扩张和投资者无狂热为标志——竟被一场意外的“流星撞击”击倒。
人们也问这次经历与我过去所经历的有何不同。
become excessive at the top (and vice versa on the downside). But in the current case, a moderate recovery – marked by reasonable growth, realistic expectations, an absence of corporate overexpansion and a lack of investor euphoria – was struck down by an unexpected meteor strike. People also ask what’s different about this episode from those I’ve lived through in the past. •
如上所述,正常的周期性起伏——以及一系列环环相扣的常规事件——与本次情况毫无关系。当前的经济下行并非源于过度乐观的商业决策或过高的增长预期落空,而是由一场外生事件突然终结了扩张期。因此,通常促成并标志周期性复苏的因素——尤其是认识到悲观情绪过度、需要刺激措施来扭转局面——这次恐怕难以奏效。既然当前问题的根源在于医学而非经济,单纯降息并向经济注入大量流动性,未必能像往常一样启动复苏。关键在于,必须先把病毒控制住。
As described above, the normal cyclical progression of ups and downs – and the normal series of events, each of which causes the next – had nothing to do with it. The current downturn didn’t result from excessively optimistic business decisions or too-high growth expectations that were disappointed, but rather from an exogenous event that brought a sudden end to the expansion. Thus the factors that result in and normally characterize a cyclical recovery – most of all the recognition that negativism is excessive and stimulative measures are required to turn things around – are unlikely to do the trick this time. Since the root cause of the current problem is medical rather than economic, merely cutting interest rates and flooding the economy with liquidity may not kickstart a recovery as usual. Rather, the virus has to be brought under control.
•
•
此外,我们的生活方式可能发生永久性改变——比如出行方式、企业对办公室的依赖,以及涉及人群聚集的活动——这些变化都会影响经济复苏的路径。
Additionally, there may be permanent changes to our way of life – altering things like travel, business’s reliance on offices, and activities involving crowds – that affect the path of recovery.
•
•
还有一件事让我无法把未来几个月看作一次普通的复苏:美国疫情暴发仅五个月后,市场和经济触底也才几个月,投资者信心就已恢复,许多资产价格重回先前高点。按历史标准,这比正常复苏快得多,似乎对仍在挑战经济的种种状况未予足够重视。
Something else that keeps me from thinking about the coming months as a normal recovery is that just five months after the onset of the pandemic in the U.S., and just a few months after the bottom was reached in the market and the economy, investor optimism has been restored and the prices of many assets have regained their prior highs. That’s a much faster recovery than normal by historic standards, and it seems to give short shrift to the conditions that continue to challenge the economy.
•
•
最后,这一次的影响极不均衡,有色人种和低收入美国人受到的冲击不成比例地严重,而此时社会对这一问题正高度敏感。他们更可能失去工作,也不太可能因资产增值而获得净资产收益——更不必说他们在疫情中更高的感染率和死亡率。相比之下,白人和白领阶层及专业人士则更可能保住了工作,并通过持有房产和参与股市从资产价格上涨中受益。
Lastly, the effects this time are highly uneven, with people of color and low-income Americans affected disproportionately, at a time of heightened sensitivity to this issue. They’re more likely to have lost their jobs and less likely to have enjoyed gains in net worth from asset appreciation – not to mention their higher rates of infection and death due to the pandemic. Whites and white-collar workers and professionals, on the other hand, are more likely to have kept their jobs and to have benefited from asset price inflation through home ownership and participation in the stock market.
我确信周期会不断重演,突出表现为从“常态”向极端——无论过高还是过低——的过度偏离,随后又回归常态,并由此走向相反方向的过度。但这并不意味着经济或市场中的每一件事都具有周期性。疫情就不是。
I’m convinced cycles will continue to occur over time, highlighted by excessive movements away from “normal” and toward extremes – both high and low – that are later followed by corrections back toward normalcy, and through it to excesses in the opposite direction. But that’s not to say that every event in the economy or markets is cyclical. The pandemic is not.
我们处在什么形态?
另一个常被问到的问题是:“经济复苏会是什么形态?”每个人都有自己的偏好答案:W 型、L 型、U 型,或者耐克的对勾形。当然,我们听到最多的
What Shape Are We In? Another frequent question is, “What shape will the economic recovery take?” Everyone has his or her favorite candidate: a W, an L, a U or maybe a Nike Swoosh. Of course, the one we hear the most

关键在于“V 形”这一说法。虽然所用术语并非关键,或许本质上只是语义问题,但我认为“V 形复苏”这一标签具有误导性。在所有用“V 形”来描述此次复苏的人中,我似乎从未见过有人为它下过定义。在我看来,一个“V”必须满足两个重要条件:
•
about is a V. While the terminology used isn’t crucial, and may basically be just a matter of semantics, I find the label “V-shaped” misleading. Of all the people who use the label “V-shaped” to describe this recovery, I don’t think I’ve ever seen anyone define it. To me, a “V” has to satisfy two important requirements: • •
第一,形态的本质必须是先下后上,也就是说,经济不会在底部滑行太久。反之,如果底部停留一段时间,那就该叫 U 形,或者用 1970 年代的说法,碟形。
第二,听到“V”这个字,我认为两侧应该基本对称。也就是说,经济回升的速度应当与下滑的速度相当。
First, the essential nature of the pattern has to be down-and-up, meaning it doesn’t spend much time skating along the bottom. One that stays down for a while, on the other hand, would be called U-shaped or what in the 1970s we called saucer-shaped. Second, when I hear “V,” it seems to me the two sides should be basically symmetrical. That is, the economy should come back at a rate similar to that at which it went down.
这第二条标准让我怀疑,本次经济复苏未必像 V 形。美国经济在第二季度以史上最高的年化速度下滑,幅度接近 33%,而回升速度肯定赶不上这个水平(不说别的,要抵消 33% 的跌幅,需要增长 49% 才行)。
多数观察者似乎认为,美国季度 GDP 会在 2020 年第四季度到 2021 年年中之间的某个时点,重新回到 2019 年同期的水平。这意味着年度 GDP 至少要等到 2021 年才能赶上或超过 2019 年。而我倾向于认为,历史记录会显示,这次衰退只持续了几个月(也许只有 2 月、3 月和 4 月),而复苏可能要花上 8 到 14 个月。至于失业率,恐怕多年内都难以回到最近 3.5% 的低点,甚至可能永远回不去。
That second criterion makes me doubt that the current recovery will be a V. The U.S. economy deteriorated in the second quarter at the highest annualized rate in history, almost 33%, and it’s certainly not going to come back at the same rate (leaving aside the fact that it takes a 49% gain to offset a 33% decline). Most observers seem to think quarterly U.S. GDP will regain its level in the corresponding quarter in 2019 sometime between the fourth quarter of 2020 and the middle of 2021. That means it’ll take at least until 2021 for annual GDP to equal or exceed 2019’s. Whereas I think history will show that the decline took place over just a few months (perhaps only February, March and April), the recovery may take 8 to 14 months. And the rate of unemployment is unlikely to return to its recent low of 3.5% for years, if ever. • • • • • • • •
新冠疫情再度抬头,导致美国部分地区经济重启被推迟或逆转。在我看来,随着大选临近,政治因素的出现降低了未来救助金像前几轮那样慷慨的可能性。有选择权的人可能几个月内都不会返回办公室,这既拖累了整体生产率,也拖累了依赖办公人群存活的企业的复苏。依赖公共交通通勤的人——或者依赖学校照看孩子的人——返岗速度可能比原本更慢。一些商业模式受到冲击的行业,如航空、度假村和娱乐业,可能需要数年才能恢复到原有水平。许多餐馆和其他小企业可能再也不会重新开张。随着行业演变、数字化程度提高,管理层也有机会观察公司在人员更少的情况下如何运转,某些工作岗位可能一去不返。最后,疫情加速了自动化、实体零售衰退等既有趋势,从而加剧了这些趋势带来的失业影响。
The renewed spike of Covid-19 cases has caused the reopening of the U.S. economy in some areas to be delayed or reversed. The emergence of politics as the general election approaches decreases, in my opinion, the likelihood that future support payments will be as generous as the early rounds. People with the choice may not return to the office for several months, holding back both overall productivity and the recovery of businesses that exist to serve office populations. People who are reliant on mass transit to commute to work – or on schools to care for their kids – may be slower to return to work than they otherwise would be. Some industries whose business models have been affected – like airlines, resorts and entertainment – may take years to recover to their prior levels. Many restaurants and other small businesses may never reopen. With industries evolving, more being done digitally and management teams having had an opportunity to watch their companies function with fewer people, some jobs may never return. Finally, the pandemic has accelerated preexisting trends such as automation and the decline of brick-and-mortar retail, and thus their contribution to job losses.
快速下行,缓慢回升:在我看来,这不是一个 V 字形。我更愿意把它看作是一个对勾,就像这样:
Fast down and slow up: to me, that’s no V. I prefer to think of it as a checkmark, like this:

市场与美联储
美国股市继续攀升,以标普 500 指数衡量,几乎回到了这一切开始的地方:2 月 19 日创下的 3386 点历史纪录。公司信贷市场同样表现强劲。以下是宏观形势的简而言之:

The Markets and the Fed The U.S. stock market continues its ascent, and as measured by the S&P 500, it’s just about back to where all this started: the all-time record of 3,386 attained on February 19. The market for corporate credit has been strong as well. Here’s the macro situation, hopefully reduced to the bare essentials: The positives: • • •
利率降至接近零的水平,抬升了投资资产的价值,并引发了一场全球竞购战,推高了资产价格。美联储向经济和市场注入了大量流动性,并为个人、企业和机构提供了其他形式的支持。美联储和财政部似乎愿意在相当长的时间内持续提供支持与刺激。
The reduction of interest rates to near zero has increased the value of investment assets and spurred a global bidding war that has raised their prices. The Fed has flooded the economy and the markets with liquidity and other forms of support for individuals, companies and institutions. The Fed and the Treasury seem willing to provide support and stimulus well into the future.

经济遭遇了历史上最严重的季度倒退。
新冠疫情仍未得到控制。
第二波疫情高峰让经济重启的努力变得更加复杂。
The economy has suffered the greatest quarterly setback in history. Covid-19 still isn’t under control. A second spike is complicating efforts to re-open the economy.
总而言之,两股巨大的力量正互相对峙:美联储与财政部对阵疾病与衰退。谁会胜出?
长期结果无人知晓,但迄今为止,哪一方占了上风是明摆着的。较低的利率提高了未来现金流的折现现值,也降低了每一项投资事先所要求的回报率。用大白话说,当联邦基金利率为零时,6% 的债券看着就像白送,于是买家竞相买入,把价格抬高,直到收益率降下来(因此我认为目前市场上 97% 的存续债券收益率不到 5%,80% 的不到 1%)。而美联储的买入推高了金融资产的价格,又把钱放进卖家手里,让他们拿去买别的资产,进一步抬高价格。基于所有这些原因,货币政策行动到目前为止占了上风,印证了那句老话:“别跟美联储对着干。”
但如果股票和上市信用工具的价格之所以处于当前水平,主要不是因为基本面因素——比如当期盈利和未来收益的前景——而是很大程度源于美联储的买入、它的流动性注入,以及由此带来的低资金成本和低要求回报率,那又意味着什么?如果高资产价格很大程度上是这类技术性因素的顺风造成的,那是否意味着这些行动必须持续下去、资产价格才能维持高位,而一旦美联储减少操作,这些价格就会下跌?
这就引出了终极问题(布鲁斯·卡什似乎每天都在问):美联储能永远撑下去吗?它创造银行准备金、购买资产、扩张资产负债表的能力有没有边界?而财政部在已经把今年的赤字干到 4 万亿美元、并且表现出打算远远超出的意向之后,它对继续跑赤字的意愿又有没有边界?
由于我在最后这三个问题上已经超出了自己的能力范围,我再次求教于我的朋友兰德尔·克罗兹纳,他是芝加哥大学布斯商学院高管项目副院长。2006 年到 2009 年间,兰迪曾担任美国联邦储备系统理事会理事。
In short, titanic forces are arrayed against each other: Fed and Treasury versus disease and recession. Which will win? No one knows about the long run, but it’s clear which has come out on top so far. Lower interest rates increase the discounted present value of future cash flows and reduce the a priori return demanded from every investment. In layman’s terms, when the fed funds rate is zero, 6% bonds look like a giveaway, so buyers bid them up until they yield less (thus I believe 97% of outstanding bonds yield less than 5% today, and 80% yield less than 1%). And Fed buying drives up the price of financial assets and puts money into sellers’ hands with which they can buy other assets, further elevating prices. For all these reasons, monetary actions have come out on top so far, validating the old maxim that “you can’t fight the Fed.” But what does it mean if the prices of stocks and listed credit instruments are where they are not primarily for fundamental reasons – such as current earnings and the outlook for future gains – but rather in large part because of the Fed’s buying, its injection of liquidity, and the resultant low cost of capital and low demanded returns? If high asset prices are substantially the result of tailwinds from technical factors such as these, does it mean those actions have to be continued in order for asset prices to remain high, and that if the Fed reduces its activity, those prices will fall? And that leads to the ultimate question (as Bruce Karsh seems to ask daily): can the Fed keep it up forever? Are there any limits on its ability to create bank reserves, buy assets and expand its balance sheet? And are there limits on the Treasury’s willingness to run deficits, now that it has taken this year’s to $4 trillion and shown an inclination to go well beyond that? Since I’m out of my depth regarding the last three questions, I’ve again turned to my friend Randall Kroszner, Deputy Dean for Executive Programs at the University of Chicago Booth School of Business. From 2006 to 2009, Randy was a member of the Board of Governors of the U.S. Federal

储备系统,因此也是联邦公开市场委员会的投票成员。以下是他的回复:
中央银行创造储备的能力没有限制,只要有人愿意——或者通过政府法令被迫——接受这些储备。这在魏玛德国的极端情况下、巴西的 20 世纪 70/80 年代,以及今天的津巴布韦都是如此,在日本当前更为温和的情况下同样成立。关键问题在于这种储备创造对货币供应量和货币需求的影响。只要实际和名义利率保持低位,财政部对赤字融资的胃口就会保持高涨。
在过去五个月里,美联储将其资产负债表扩大了 3 万亿美元,财政部则增加了 3 万亿美元的预期赤字,经济流动性总计增加了 6 万亿美元,可能还会更多。人们通常认为,如此规模的流动性增加会相对于供应提升商品需求,从而引发通胀上升,正如它已经对金融资产所做的那样。(但需注意,即便利率在十年间保持低位、如今接近零,通胀也从未接近美联储 2% 的目标。如果增长持续疲软、通胀保持低位,美联储很可能认为它可以继续采取积极干预的政策。)以下是兰迪·克罗兹纳的观点:
我认为关键点在于:无论是日本——日本央行的资产负债表超过国内生产总值的 100% 且仍在快速增长,还是欧洲央行——资产负债表超过欧元区国内生产总值的 50% 且不断扩大,或是美联储——资产负债表刚刚超过美国国内生产总值的三分之一且持续增长,通胀都低于 2% 的目标,短期和长期通胀预期也保持低位。即使在美国新冠疫情前以 2%-3% 的速度增长时,我们也没有看到通胀或通胀预期的上升。只要对银行储备和现金这类超流动性安全资产的需求持续旺盛,央行就能维持庞大的资产负债表——甚至进一步扩大——而不会导致货币供应量急剧增加从而引发通胀。疫情走向和政策应对的持续不确定性无疑会让安全流动资产的需求在一段时间内保持高位。
同样,人们也通常认为,这种货币扩张可能导致美元走弱、评级机构下调美国信用评级、国债利息成本上升,以及/或美元作为世界储备货币的地位受到威胁。所有这些都可能增加美国偿还扩张后国债的难度,反过来导致更高的赤字。这并非白日做梦,因为在 3 月(美联储/财政部计划宣布之时)至 7 月底期间,美元兑一篮子货币贬值了 9%。这可能与美元受益于避险资金流入的倾向有关——这种倾向可能在 3 月达到顶峰——而当恐慌消退时美元表现则较差。但美元今年迄今仍下跌了 3%,7 月尤其疲软。
这些是关于货币扩张的传统担忧。现代货币理论(“MMT”)随时准备反驳这些观点。实际结果无法预知。但银行储备、美联储资产负债表和联邦赤字可以无限增加而没有任何负面效应,这真的合理吗?我的回答一如既往:走着瞧。不过,让我让兰迪·克罗兹纳对这一主题做最后总结:
Reserve System and accordingly a voting member of the Federal Open Market Committee. Here’s his reply: There is no limit on the ability of a central bank to create reserves, as long as someone is willing – or through government edicts, forced – to take them. This was true in the extreme circumstances of Weimer Germany, Brazil in the 1970s/80s, and it is true Zimbabwe today, as well as in the much more benign current situation in Japan. The key question is the impact of that reserve creation on money supply and the demand for money. Treasury’s appetite for deficit financing will remain high as long as real and nominal interest rates remain low. In the last five months, the Fed has swollen its balance sheet by $3 trillion and the Treasury has added $3 trillion to the expected deficit, for a total increase of liquidity in the economy of $6 trillion, probably with more to come. It’s normal to assume that an increase in liquidity on that order will increase the demand for goods relative to the supply, bringing on increased inflation, as it already has for financial assets. (Note, however, that even with interest rates low for a decade and near zero today, inflation hasn’t come close to the Fed’s target of 2%. If growth remains weak and inflation stays low, the Fed is likely to believe it can continue an activist regime.) Here’s Randy Kroszner’s view: I think this is the key point: whether it is Japan, where the BoJ’s balance sheet exceeds 100 percent of GDP and continues to grow rapidly, or the ECB with a balance sheet of more than 50 percent of Eurozone GDP and growing, or the Fed with a balance sheet of just over a third of US GDP and growing, inflation has been below the 2 percent target, and expectations of inflation over short and long horizons remain low. Even when the U.S. was growing 2-3 percent pre-Covid, we didn’t see an uptick in inflation or inflation expectations. As long as there continues to be a very large demand for super liquid safe assets like bank reserves and cash, the central banks can maintain large balance sheets – and even increase them – without a sharp increase in money supply that ignites inflation. The ongoing uncertainty over the course of the virus and the policy responses will undoubtedly keep the demand for safe liquid assets high for some time. It’s also normal to assume that monetary expansion like this can lead to a weaker dollar, downgrades of the U.S.’s creditworthiness by rating agencies, higher interest costs on national debt, and/or jeopardy to the dollar’s status as the world’s reserve currency. All these things could increase the difficulty of servicing the U.S.’s expanded national debt, feeding back into still-higher deficits. This isn’t pie-in-the-sky, since between March (when the Fed/Treasury programs were announced) and the end of July, the dollar depreciated by 9% versus a basket of currencies. That could be related to the dollar’s tendency to benefit from flight to quality, which probably reached its apex in March, and to do less well when fear recedes. But it’s still down 3% for the year to date and particularly weak in July. These are the traditional concerns with regard to monetary expansion. Modern Monetary Theory (“MMT”) stands ready to refute them. The actual outcome is unknowable. But does it really make sense that bank reserves, the Fed balance sheet and the federal deficit can be increased ad infinitum without negative effects? My answer is the usual: we’ll see. But I’ll let Randy Kroszner have the last word on the subject:

我总是觉得很难理解 MMT(现代货币理论)——它似乎暗示着不存在预算约束。我对此持非常老派的观点,仍然相信预算约束的存在。像阿根廷、津巴布韦等国家表明,不那么“现代”的货币理论仍然适用,至少在那些地方是这样。这中间需要一种微妙的平衡:市场确实允许像日本和美国这样信誉良好的政府借入巨额资金而无需太多担忧,但关键问题是,什么可能动摇这种信誉?如果这种情况真的发生,后果无疑是灾难性的。(强调为后加)
I always find it difficult to understand MMT – it seems to suggest that there isn’t a budget constraint. I’m very old-fashioned about that and still believe in them. Countries like Argentina, Zimbabwe, etc. show that the less “modern” monetary theory still applies, at least in those places. There is a delicate balancing act: Markets certainly allow credible governments like Japan and the US to borrow enormous amounts without much concern, but the key issue is what could undermine that credibility? If that does happen, the consequences certainly could be titanic. (Emphasis added)
看多方论点
疫情给许多人带来的一个好处,就是有了大量阅读和思考的时间,我借此机会补了补课,研究了一番支持当前股票和债券市场价格的各种论点。以我“价值”投资的倾向和公认的保守偏见来看,这个过程颇有收获。而且做这件事很有必要,因为近来对受损经济和偏高市盈率保持谨慎,显然并没有得到回报。
就股市而言,有人提出了几点理由来为当前水平辩护——这个水平让价值投资者百思不得其解——并断言其前景光明:
第一点是,许多投资者低估了低利率对估值的影响。简而言之,股票市场应该有多少收益率?不是股息率,而是盈利收益率:即盈利与价格的比率(也就是市盈率的倒数)。简单来说,当美国国债收益率不到 1%,再加上传统的股票风险溢价,也许盈利收益率应该在 4%。这个 4/100 的收益率对应的市盈率(倒数)是 100/4,即 25。因此标普 500 指数不应该按传统的 16 倍盈利交易,而应该高出大约 50%。
还有人认为,即便如此,这也低估了实际情况,因为这忽略了公司盈利会增长,而债券利息不会增长这一事实。因此,股票的要求回报率不应该是(债券收益率 + 股票风险溢价)如上所述,而应该是(债券收益率 + 股票风险溢价 - 增长率)。例如,如果标普 500 的盈利将以每年 2% 的速度增长到永远,那么合适的盈利收益率就不是 4%,而是 2%(对应市盈率 50)。而且,从数学上讲,对于一家增长率超过债券收益率与股票风险溢价之和的公司,合适的市盈率是无穷大。照这个逻辑,股票可能还有很长的路要走。
看多方其余的论点大多围绕市场领先的科技公司的特殊性:

The Bull Case One thing the pandemic has given many of us is lots of time for reading and thinking, and I’ve had a chance to bone up on some of the arguments supporting current stock and bond market prices. Given my “value” leanings and acknowledged conservative bias, I found it a valuable process. And it was important to undertake it, since it certainly can’t be said that caution regarding the damaged economy and elevated p/e ratios has been rewarded of late. As for the stock market, several points are advanced to justify the current level – which is so mystifying to value investors – and assert its bright future: The first is that many investors have underestimated the impact of low rates on valuations. In short, what should the stock market yield? Not its dividend yield, but its earnings yield: the ratio of earnings to price (that is, p/e inverted). Simplistically, when Treasurys yield less than 1% and you add in the traditional equity premium, perhaps the earnings yield should be 4%. That yield of 4/100 suggests a p/e ratio (the inverse) of 100/4, or 25. Thus the S&P 500 shouldn’t trade at its traditional 16 times earnings, but roughly 50% higher. Even that, it’s said, understates the case, because it ignores the fact that companies’ earnings grow, while bond interest doesn’t. Thus the demanded return on stocks shouldn’t be (bond yield + equity premium) as suggested above, but rather (bond yield + equity premium - growth). If the earnings on the S&P 500 will grow to eternity at 2% per year, for example, the right earnings yield isn’t 4%, but 2% (for a p/e ratio of 50). And, mathematically, for a company whose growth rate exceeds the sum of the bond yield and the equity premium, the right p/e ratio is infinity. On that basis, stocks may have a long way to go. The rest of the bulls’ arguments mostly surround the exceptional nature of the market-leading tech companies: • • •
它们的增长速度远超过去的大型企业,而且增长趋势更不容易呈现周期性波动。
事实上,当前这场危机,伴随着更多日常生活转移到线上,(a)加速了它们的增长,或(b)为它们提供了机会,展示出无论在何种环境下都能持续增长的能力。
它们拥有规模优势、技术优势和网络效应,使得抵御竞争的能力远胜于旧经济时代的前辈们。
They grow much faster than the large companies of the past, and their growth is much less likely to prove cyclical. In fact, the current crisis, with the accompanying movement on-line of a larger share of everyday life, has (a) served to accelerate their growth or (b) given them an opportunity to demonstrate their ability to grow regardless of conditions in the environment. They have scale, technological advantages and network effects that give them much greater protection against competition than their old-economy predecessors enjoyed.

(不过,相应地,监管层对其市场力量的遏制构成了它们最大的风险。)
得益于知识产权作为产品主要“原材料”的角色,这些公司大多能以极低的边际成本生产额外销售单位。
同样,它们几乎不需要额外资本就能实现扩张——如果有的话(排名前五的科技公司全部处于“净现金”状态,即现金持有量超过债务)。
最后,它们当前的高市盈率意义小于往常,因为这些科技巨头大幅少报了利润:如果它们削减客户获取成本和研发等开支,并满足于较低(但仍属快速)的增长,就能报告远为更高的利润。
(Correspondingly, however, regulatory efforts to restrain their market power represent their greatest risk.) Thanks to the role of intellectual property as the main “raw material” in their products, most of these companies can create additional units for sale at very low marginal cost. Likewise, they can grow without much additional capital, if any (all five of the top tech firms are in a “net cash” position, meaning their cash holdings exceed their debt). Finally , their high p/e ratios today mean less than usual, since these tech champions are vastly under-reporting earnings: if they were to cut back on things like customer-acquisition costs and R&D and settle for lower (but still rapid) growth, they could report far higher earnings.
因此,据说怀疑论者严重低估了技术领军企业的增长能力,以及它们拉动普通股整体增长率的作用。这些企业每天都在成长,它们在股票指数和美国企业界中的占比也随之不断提高,形成了一个良性循环。
因此,既然这些大型科技股巨头在股市中所占比重越来越大,看空者就必须拿出一个理论,解释它们为何应该下跌。否则,你就只能押注非科技板块大幅下挫、拖累指数走低——尽管这些板块已经跌了不少。
标普 500 指数今年基本持平,但如果没有 FAAMG(Facebook、苹果、亚马逊、微软和谷歌,即权重最大的五只成分股)以及其他科技/软件股,指数会低得多。(今年迄今为止,前五大股票平均上涨 36%,而全部 500 只股票的涨跌幅中值为负 11%。)在这种情况下,FAAMG 加科技/软件股大幅上涨是否合理?看起来确实合理,因为(a)新冠疫情在多个方面加速了技术的普及,从而推动了这些公司的增长,(b)当前超低利率为更高的市盈率提供了合理性(见上文)。反过来,如果科技巨头在这种背景下持平——或者只是与指数其他成分股表现一致——我们反而可能会说哪里出了问题。
我不知道这些看多论点是否完全正确,还是仅仅因为它们推动了标普 500 指数在过去四个月上涨 46% 而显得光彩夺目。无论如何,我想把看多逻辑分享出来,作为一种公共服务,也是因为它显然有其合理性……而且到目前为止无疑是赢家。
Thus, it’s said, the skeptics seriously underestimate the ability of the technological leaders to grow, and to pull up the overall growth rate for the universe of common stocks. They grow every day, and so does their representation in the equity indices and in corporate America, creating a virtuous circle. Thus, with these dominant large-cap tech companies making up a large and growing percentage of the stock market, to be bearish one has to have a thesis on why they should fall. Or else you would have to bet on the non-tech sectors to decline a great deal and pull down the averages – despite the fact that they’re already down a lot. The S&P 500 is basically flat on the year, but without FAAMG (Facebook, Apple, Amazon, Microsoft and Google, its five heaviest-weighted components) and other tech/software stocks, it would be considerably lower. (The top five are up by an average of 36% so far this year, while the median change for all 500 stocks is minus 11%.) Does it make sense that the FAAMG-plustech/software stocks are up a lot in this context? It seems that it does, because (a) Covid-19 has accelerated tech adoption in many ways, and thus these companies’ growth, and (b) today’s ultra-low interest rates justify much higher p/e ratios (see above). If instead the tech giants were flat against this backdrop – or had just performed in line with the rest of the index – we’d probably say something was wrong. I don’t know whether these bullish arguments are absolutely correct or merely have gained luster thanks to their having driven the 46% gain of the S&P 500 over the last four months. Regardless, I want to share the bull case as a public service and because it has obvious merit . . . and certainly has won out thus far.

一方面,股票和信贷市场出人意料地迅速回升至接近历史高点,尽管新冠疫情仍未得到遏制,经济要恢复到 2019 年的水平还需数月之久(而要达到当时市场首次触及高点时所预期的盈利水平,则需要更长时间)。因此,当前的市盈率异常之高,而债务收益率则

在史无前例的低位。类似这样的极端估值,通常都会伴随着“这次不一样”的辩解,而这四个字往往会让投资者陷入困境。
at unprecedented lows. Extreme valuations like these are usually justified with protests that “this time it’s different,” four words that tend to get investors into trouble. •
另一方面,约翰·邓普顿承认,当人们说情况不同时,20% 的时候他们是对的。在去年六月份关于这个主题的一份备忘录中,我写道:“在科技和数字商业模式等领域,我打赌情况不同的概率会超过邓普顿所引用的 20%。”当然可以说,当今的科技巨头比过去的龙头企业更聪明、更强大,拥有更大的领先优势,而且它们为自己打造了良性循环,将带来数十年的快速增长,从而支撑起远超历史常态的估值。如今超低的利率进一步为异常高的估值提供了理由,而且这些利率短期内不太可能上升。
On the other hand, John Templeton allowed that when people say things are different, 20% of the time they’re right. And in a memo on this subject in June of last year, I wrote, “in areas like technology and digital business models, I’d bet things will be different more than the 20% of the time Templeton cited.” It certainly can be argued that the tech champions of today are smarter and stronger and enjoy bigger leads than the big companies of the past, and that they have created virtuous circles for themselves that will bring rapid growth for decades, justifying valuations well above past norms. Today’s ultra-low interest rates further justify unusually high valuations, and they’re unlikely to rise anytime soon.

但再说第三层,即便是最优秀的公司,其股票也可能被高估,事实上,它们往往是最容易高估的股票。1968 年我初入此行时,当年号称“漂亮五十”的那些公司——运用着当时的神奇科技,如计算机(IBM)和干式复印(施乐)——同样被预期增长会超越其他公司,并被认为对竞争和经济周期具有免疫力,因此获得了前所未有的高估值倍数。此后五年里,它们的股东几乎亏光了全部本金。
But on the third hand, even the best companies’ stocks can become overpriced, and in fact they’re often the stocks most likely to do so. When I first entered the business in 1968, the companies of the Nifty Fifty – deploying modern wonders like computing (IBM) and dry copying (Xerox) – were likewise expected to outgrow the rest and prove impervious to competition and economic cycles, and thus were awarded unprecedented multiples. In the next five years, their stockholders lost almost all their money.
基于这些以及其他种种原因,我认为当今的股票和信贷市场正如往常一样迷雾重重。我们做出结论,既受自身远见不足所限,又受乐观或悲观倾向的影响。经验告诉我们,要得出正确答案有多难。这让我想起查理·芒格关于解开市场之谜的一句至理名言来作结:“本就不该容易。谁觉得容易,谁就是蠢货。”
For these reasons and more, I find today’s stock and credit markets opaque . . . as usual. We reach our conclusions, limited by the inadequacy of our foresight and influenced by our optimistic or pessimistic biases. And we learn from experience how hard it is to get the answer right. That leads me to end with a great bit of wisdom from Charlie Munger concerning the process of unlocking the mysteries of the markets: “It’s not supposed to be easy. Anyone who finds it easy is stupid.”

附言:第二季度实际 GDP 的暴跌规模之大,令我们所有人震惊。此前,从未有人见过经济在三个月内萎缩三分之一!然而,结合撰写这份备忘录时对数据的思考,却引发了一些疑问:
P.s.: We were all struck by the enormity of the reported decline in second quarter real GDP. Before now, no one’s ever seen an economy contract by one-third in three months! However, thinking about the results in connection with writing this memo raised some questions: • •
•
•
我最初以为第二季度 GDP 比去年第二季度下降了 1.81 万亿美元,即 32.9%。但实际降幅仅为 0.45 万亿美元,从 4.76 万亿美元降至 4.31 万亿美元,降幅为 9.5%。会不会是从第一季度 4.63 万亿美元的基础上下降了 1.81 万亿美元,使第二季度 GDP 降至 2.82 万亿美元?但从 4.63 万亿美元降至 2.82 万亿美元意味着下降了 39.1%。而且,无论如何,这都不可能,因为实际第二季度 GDP 为 4.31 万亿美元。或者这是从 2019 年全年实际 GDP 19.09 万亿美元预计下降 1.81 万亿美元?不,那仅代表 9.5% 的降幅。
I had immediately assumed Q2 GDP was down $1.81 trillion, or 32.9%, from Q2 of last year. But the actual decline was only $0.45T, from $4.76T to $4.31T, or 9.5%. Could it have been a decline of $1.81T from Q1’s $4.63T, bringing Q2 GDP to $2.82T? But going from $4.63T to $2.82T would mean a decline of 39.1%. And anyway, that couldn’t have been the case, since actual Q2 GDP was $4.31T. Or was it a projected drop of $1.81T from actual 2019 full-year GDP of $19.09T? No, that would represent a decline of only 9.5%.
这些数字我看不懂,于是请教了布雷恩资本的康拉德·德夸德罗斯帮我理解。他的回答让我意外,你听了可能也会。
I couldn’t make sense of the numbers, so I consulted Conrad DeQuadros of Brean Capital for help understanding them. I found his answer surprising, and you might as well.

你是否想过,第二季度 GDP 报告中的 32.9% 下滑究竟意味着什么?
答案是:如果未来三个季度 GDP 以 2020 年第二季度的同样速度下滑,那么 2021 年第一季度 GDP 将比 2020 年第一季度低 32.9%。如果这听起来复杂得难以置信,那么康拉德的解释也同样复杂:
•
•
Have you thought about what the reported 32.9% decline in second quarter GDP really means? Answer: it’s the percentage by which 1Q2021 GDP would be below 1Q2020 GDP if GDP were to decline in the next three quarters at the same rate as it did in 2Q2020. If that seems incredibly complex, so was Conrad’s explanation: • •
•
•
• •
今年第二季度实际国内生产总值(未做季节性调整或年化处理)为 4.31 万亿美元,较第一季度的 4.63 万亿美元(同一口径)下降 7.0%。
如果随后三个季度环比也下降 7.0%,那么 2020 年第三季度将为 4.00 万亿美元,第四季度为 3.72 万亿美元,2021 年第一季度为 3.46 万亿美元。(这些数字你永远不会在正式报告中看到,因为它们省略了季节性调整、年化处理和通胀调整。但我认为,就这些讨论目的而言,它们呈现了一幅公允的图景,即便在技术上不够精确。)
正是 2021 年第一季度 GDP 的 3.46 万亿美元这一数字——经过年化处理及季节性和通胀调整后——将比 2020 年第一季度 GDP 低 32.9%。
有意思的是,在上述假设的下降之后,2020 年第二季度至 2021 年第一季度这四个季度(如前所列)的 GDP 总和将为 15.49 万亿美元。但这仅比此前四个季度(2019 年第二季度至 2020 年第一季度)实际总和 19.11 万亿美元下降 18.9%。
Actual second quarter real GDP (without seasonal adjustment or annualization) was $4.31 trillion. That was down 7.0% from $4.63T in Q1 on the same basis. If the three subsequent quarters were also down 7.0% from quarter to quarter, 3Q2020 would be $4.00T, 4Q2020 would be $3.72T, and 1Q2021 would be $3.46T. (These are figures you’d never see, since they omit seasonal adjustment, annualization and adjustment for inflation. But I think they present a fair if not technically correct picture for these purposes.) It’s that figure of $3.46T for 1Q2021 GDP that – after annualization and adjustments for seasonality and inflation – would be 32.9% below GDP in 1Q2020. Interestingly, after the assumed declines, GDP in the four quarters 2Q2020 through 1Q2021 (as enumerated above) would sum to $15.49T for the year. But that would be down only 18.9% from the actual total of $19.11T in the four prior quarters (2Q2019 through 1Q2020).
所以,再说一遍,第二季度报告的 32.9% 的降幅,是 2020 年第一季度 GDP 与假设季度 GDP 继续按 2020 年第二季度的速度下降时的 2021 年第一季度 GDP 预测值之间的差额。但没有人认为这种情况会发生。这意味着 32.9% 是一个极具误导性、被夸大的数字。没有什么东西下降了三分之一,也不大可能有任何东西会这样下降。
名义 GDP 也是如此。从 2020 年第一季度到第二季度的 GDP 降幅报告为 2.15 万亿美元,即 34.3%,但这也是年化数字。2.15 万亿美元的降幅是 2020 年第一季度年化 GDP 的 21.56 万亿美元与 2020 年第二季度年化 GDP 的 19.41 万亿美元之间的差额。但从第一季度到第二季度,实际季度名义 GDP 的降幅仅为 0.38 万亿美元(从 5.25 万亿美元降至 4.87 万亿美元),即 7.2%。那么,报告的第二季度年化降幅 2.15 万亿美元和 34.3% 又意味着什么呢?同样什么也不意味着。
在商业世界里,我们会看 2020 年第二季度 GDP 与 2019 年第二季度 GDP 之间的关系。如上所述,实际第二季度 GDP 从 2019 年的 4.76 万亿美元下降到 2020 年的 4.31 万亿美元,降幅为 9.5%。名义第二季度 GDP 从 2019 年的 5.36 万亿美元下降到 2020 年的 4.87 万亿美元,降幅为 9.1%。显然,这两个同比降幅与报告的 32.9% 的降幅没有任何相似之处。
以下是康拉德的结论:
年化在正常时期有助于将一个季度与最近几年进行比较,但在当前情况下不太有用。……大多数其他主要经济体并不报告 GDP 的年化变化(例如,当欧元区 GDP 的变化在 8 月 3 日报告时,将是非年化变化)。指望第二季度的下降持续一整年,是不合理的。
最后,在年末,每年报告的 GDP 是四个季度实际美元 GDP 的总和(未经年化或季节性调整)。因此,当 2020 年 GDP 报告出来时,不太可能显示 32.9% 或类似的降幅。在报告的年化 GDP 环比降幅第一季度为 5.0%、第二季度为 32.9% 之后,摩根士丹利(例如)预计第三季度增长 21.3%,第四季度增长 0.3%。如果我们像处理季度投资组合回报那样,把这些季度百分比变化连起来,我们就会……
So, again, the 32.9% reported decline in Q2 is the difference between 1Q2020 GDP and projected 1Q2021 GDP assuming quarterly GDP continues to fall at the 2Q2020 rate. But nobody expects that to happen. Which means the 32.9% is a highly misleading, exaggerated figure. Nothing went down by one-third, and nothing is likely to do so. It’s the same for nominal GDP. The decline in GDP from 1Q2020 to 2Q2020 was reported as $2.15T, or 34.3%, but those also are annualized figures. The $2.15T decline is the difference between 1Q2020 annualized GDP of $21.56T and 2Q2020 annualized GDP of $19.41T. But the decline in actual quarterly nominal GDP from Q1 to Q2 was only $0.38T (from $5.25T to $4.87T), or 7.2%. So what do the reported annualized Q2 declines of $2.15T and 34.3% mean? Also nothing. In the business world, we’d be looking at the relationship between GDP in 2Q2020 and what it was in 2Q2019. As mentioned above, real Q2 GDP fell from $4.76T in 2019 to $4.31T in 2020, for a decline of 9.5%. Nominal Q2 GDP fell from $5.36T in 2019 to $4.87T in 2020, down 9.1%. Obviously, neither of these year-over-year declines bears any resemblance to the reported 32.9% decline. Here’s Conrad’s conclusion: Annualization is useful in normal times for comparing a quarter to the recent prior years, but not very useful for current circumstances. . . . Most other major economies do not report annualized changes in GDP (for example, when the change in Eurozone GDP is reported [on August 3], it will be a non-annualized change). It is not reasonable to expect the second quarter’s drop to continue for a year. Finally, at year-end, the GDP that’s reported for each year is the sum of the actual dollar GDP in its four quarters (without annualization or seasonal adjustment). Thus, when GDP is reported for 2020, it’s unlikely to show a decline of 32.9% or anything like it. After reported quarter-over-quarter declines in annualized GDP of 5.0% in Q1 and 32.9% in Q2, Morgan Stanley (for example) expects increases of 21.3% in Q3 and 0.3% in Q4. If we were to chain those quarterly percentage changes, as we do with quarterly portfolio returns, we

如果把它们直接加总,年跌幅就是 22.5%。或者,如果我们(错误地)简单相加,忽略复利效应,跌幅则为 16.3%。但摩根士丹利预计,2020 年全年 GDP 同比仅下降 5.3%,第四季度环比下降 6.2%。所以我的心得是,按年化计算的季度环比变化相当没有意义,包括第二季度报告的 32.9% 的跌幅在内。
would get a decline for the year of 22.5%. Or if we (incorrectly) added them together, ignoring the impact of compounding, we would get a decline of 16.3%. But MS expects full-year 2020 GDP to be down only 5.3% year-over-year and 6.2% Q4-over-Q4. So what I’ve learned is that annualized quarter-over-quarter changes are quite meaningless, including Q2’s reported decline of 32.9%.
