要改革,流动性不是出路

寄望于流动性政策,只会延误对经济危机的应对,延长经济衰退

  全球经济正陷入深渊。在这场危机中,人们对增加流动性寄予厚望。过去两个月,中国大幅提高了信贷规模。自2008年11月以来,中国股市跑赢其他市场约40%。这些都吸引了全球投资者的目光。

  全球市场屡次因中国动向而起伏。投资者清楚,下一次经济上升,尽管尚不知何时、以何种方式发生,但必将与中国密切相关。由于美国仍需数年解决“双赤字”难题,欧洲和日本仍受困于老龄化问题,中国似乎是推动经济好转的惟一希望。

  然而,对流动性的信心与依赖,似乎有点表错了情。在格林斯潘时代,流动性被赋予了神奇力量,金融从业人员花费大量的时间讨论它,却没有几个人知道流动性到底是什么。

流动性政策缘何失效

  当中央银行宣称正在向市场注入流动性时,它购入某些金融资产,例如,以现金买入政府债券。当这一操作完成时,其资产负债表发生了变动:在负债方,它欠金融体系的钱增加;在资产方,它新增了更多证券。金融系统资产负债表的记录则完全相反:拥有更多的货币和更少的证券。手中的货币增加,金融体系可能会倾向于增加贷款,或是买入更多证券。前者将提高借款人的支出能力,后者将提升资产价格。经济学家通常关注于前者,而金融从业人员关注的是后者。

  流动性经凯恩斯的著述开始受到推崇。早前,它曾一度等同于投机。凯恩斯主要关注的,是在20世纪初期频繁发生的经济衰退中如何刺激需求。流动性通常与财政刺激相关,例如,通过购买财政债券以支持政府赤字。财政刺激支持的主要理念是,当某人失业时,令其有事可做(即便他的这份新工作完全没有用处),这样,他可以凭借收入进行支出,进而引发一连串的经济活动。当失业率居高不下时,财政赤字可以起到改善作用。

  与之相反,经济学家熊彼特提出,经济衰退可被认为是“创造性破坏”(creative destruction),即经济衰退是淘汰弱者、为新企业赢得空间的过程。在他的理论中,经济衰退预示着进步和创新。政府为熨平经济波动实施干预,无法达到预期目的。尽管经济周期狂暴循环,19世纪繁荣的经济似乎支持了熊彼特的理论。

  然而,这个世界并不是像凯恩斯或是熊彼特所阐述的那样非黑即白。当经济处于严重低迷期时,将引发社会革命。20世纪30年代和40年代的革命,与1929年的“大萧条”密切相关。在严酷的经济衰退期,政府有责任刺激经济增长,这一点凯恩斯是对的。然而,财政刺激不能在长期内发挥作用,过度依赖刺激可能将引发滞胀。经济衰退也可以起到将业绩不佳的企业淘汰出局的作用。

  在20世纪70年代的滞胀时期,流动性并不是经济管理的有效工具。工人们在预见到了货币增长带来的通货膨胀冲击后,要求提高工资以抵消通胀的影响,但是,工资的增长将立即传导至CPI,引发通胀抬头。货币扩张与通胀之间存在直接的传导路径。因此,中央银行放松银根仅仅会推高通胀,而无助于刺激需求。当沃尔克(Paul Volker)担任美联储主席、大幅提高联邦基金利率以打击通胀后,滞胀时代结束了,他的举措也为后来低通胀时代的来临奠定了基础 。

  在格林斯潘接任美联储主席时,通胀预期较低。当格林斯潘增加货币供给后,货币首先流入了资产市场,引发资产通胀,并有效地刺激了需求的增加。由于来自发展中国家的逾10亿名工人融入全球经济体系,全球化拉长了低通胀时代延续的时间。金融市场逐步适应了格林斯潘流动性政策带来的效果。随着“银弹” 攻势重振经济后,大部分金融人士开始对流动性顶礼膜拜。

  自当前这场经济危机在2007年8月爆发后,各国中央银行再次祭出了流动性法宝作为应对措施。对流动性扩张政策的信任,提高了金融市场的信心,并在数月内稳定了市场。但在2008年,这一政策开始失效,增加流动性并没有推升资产价格或是改善需求。全球经济和金融市场陷入了一个恶性循环

为什么流动性扩张政策这次失效了呢?

  尽管金融人士通常把流动性看做类似于“免费的钱”(free money),但事实上,它是一种短期债务。当有足够多的家庭或是企业愿意借款消费时,它就会发生作用;但当信贷泡沫破裂,不管利率多么低,都没有几个家庭或是企业再有借款的意愿。此时,流动性政策彻底失效。用货币经济学的术语描述,就是流动性增加而货币乘数缩小。

怪信心还是怪钱袋

  中国的情况与西方不同,总体而言并不存在高杠杆率问题,尤其是家庭部门没有太多债务。这就是当中国扩张流动性时全球如此瞩目的原因。中国拥有将流动性转化为需求的潜力。然而,中国家庭部门跟政府部门、企业部门之间的结构性不平衡,妨碍了流动性向有效需求转化。

  中国当前的流动性来源于高额贸易顺差。由于中国央行并没有像以前那样,发行央票以对冲贸易盈余,目前,流动性都集中在银行体系当中,而银行以接受贴现票据的形式,将部分资金贷给国有企业。由于以这种形式获得的贷款利率都相当低,国有企业可以将资金存起来而不用担心成本,甚至有时候还小有获利。这在会计上会导致银行体系资产负债表迅速扩张。

  然而,这样的贷款在短期内不会转化为需求。大部分企业,尤其是资本密集型企业都面临产能过剩。例如,钢铁企业大约有30%的产能过剩;造船业面临大量违约订单,如果不是大多数,至少许多家造船厂将面临破产风险。中国的供给方产能大量过剩,积压了太多库存,如果银行借款援助它们继续生产,只能让它们越陷越深。增加贷款并不能推动经济复苏。

  对政府项目放贷可以增加有效需求。财政刺激项目具有乘数效应,银行贷款可以放大这一效果。今年,中国政府编制了近1万亿元人民币的财政预算赤字(约占2009年GDP的3%)。这一刺激政策将稳定经济,但不会推动其重返高速增长状态。

  中国经济疲软的根源,在于出口下滑和房地产市场泡沫破裂。前者是全球信贷泡沫破裂的必然结果。全球化使得生产活动从发达国家转移至发展中国家。在这一背景下,西方各国央行容忍资产泡沫的存在,使得西方消费者能够享有资产泡沫带来的好处,维持既往的生活方式,而无视工资状况能否支持这样的消费水平。随着泡沫的破裂,他们对来自发展中国家的出口商品的需求,也减少至与其工资水平相匹配的程度。

  中国的房地产市场存在泡沫。在许多城市,每平方米均价约等于或高于月平均工资的3倍,而建筑开工总量相当于目前房屋存量的三分之一。高房价和高建筑量并存的现象,必将不可持续。2008年前那种强劲的购房需求只是一个泡沫现象,原因在于消费者预计房价将进一步走高,试图赶在房价高不可及之前,及早买房、锁定风险

  为了解决需求疲软问题,中国政府必须刺激居民消费,以抵销出口下滑带来的影响;降低房地产购买成本,以消化眼下的存量房屋。这两个问题不解决,中国经济便不能重现高速增长信心并不是中国家庭消费相对疲软的原因,事实上,收入低、财富积累少,才是真正的肇因。最迅速的解决办法是,政府将持有的上市国企股份分配给民众。这对消费而言,必将产生一个强大的短期效应。随着经济高速发展推动企业经营利润提高、股票增值,消费者的有效需求将进一步得到支撑,带动经济持续繁荣发展。

以新泡沫救旧泡沫不可为

  1998年,中国政府将公有住宅以象征性的低价出售给个人,启动了住房制度的改革,为后来房地产市场的繁荣奠定了基础。如果政府将国企的股份分配给家庭部门,将确保新一轮的十年经济增长。

  如何分配这些股票呢?政府可以选择一家国有银行,通过居民身份证号码自动为每一个居民开立账户。居民可以凭借身份证,向指定银行的任一网点获取股份。

  部分人士认为,贫苦民众在获得股票后可能会以低价出售,这一幕曾在20世纪90年代的俄罗斯上演。但我认为,中国不会重蹈俄罗斯覆辙。现在,10%的中国人拥有股票经纪账户,而当时俄罗斯仅有0.5%。现在的中国人热衷于股票交易,会谨慎处理手中持有的国企股份。此外,国企还可以分配红利,这将让人们更为珍视手中的股票。我预计,分配红利的措施,将比那些产能过剩行业的国企把钱大把花在网络设备、计算机、仪器等一次性支出项目上,更有利于推动经济增长。

  也有人认为,国企股份应该用于补充社会保障基金。缺乏社会保障也是目前消费疲软的原因之一。但我怀疑,人们是否会将存放在社会保障基金中的资金与自己口袋里的人民币等同视之。来自发达国家的研究显示,民众会将前者打个60%的折扣。因此,将货币发放到居民的口袋里,对经济的促进作用将更为显著。

  为消化现有的存量房屋,每平方米购房成本应该降至月平均工资的1.5倍。在国际上,这也是一个不低的标准。但考虑到中国将在未来15年或是更长的时间内维持高速经济增长,房地产价格可以高于国际水平。购房成本下降,需要通过房价降低和加大税收激励两种同样重要的方式,双管齐下。

  部分人士希望,扩张流动性能够抬升资产市场价格,进而改善经济,这实际上相当于制造一个新的泡沫。在2000年高科技泡沫破裂后,格林斯潘采用的就是这种做法。时过境迁,格氏昔日的光辉开始成为今日的梦魇。制造新泡沫以应对旧泡沫破裂的后果,是不负责任的行为,即便可以为,也不应为之。

  我担心这一悲剧在中国重演。在2008年12月和2009年1月,确实有部分资金流入了股市,在三个月内,股市出现了40%的反弹,创下近期高位。不过,要想在经济衰退时期吹出一个股市泡沫,实在是极其困难,现代历史上还不曾有过,因为投机者此时通常选择快速获利了结。

  此外,试图通过投机来推升中国房地产市场价格的做法,也只不过是一个“白日梦”。当前在建的以及完工的房屋,是有史以来数量最多的,即便是借助最佳的政策组合,也需要三年的时间来消化。

  中国的经济问题在于疲软的居民需求,其根源在于民众收入低、财富积累少。信心虽然是一个影响因素,但并不是最重要的因素。过去十年,强劲的出口支撑了中国的高额投资。如今,我们迫切希望居民需求可以取代出口,令投资获益。最快的解决办法,是将政府财富分配给公众。寄望于流动性政策,只会延误对经济危机的应对,延长经济衰退。■

Reform, not liquidity, is the way out

Andy Xie
March 15, 2009

The global economy is sinking into the abyss. Big trading economies like Japan, Korea, and Taiwan see their exports halved. The US’s unemployment hit 8.1%. Stock markets around the world have dived below their lows last November and are into the valuation levels last seen in the 1970s-the horrifying decade of stagflation. The share price of Citigroup, the erstwhile financial supermarket, has sunk to one dollar. It was $55 in 2007. The share price of HSBC is diving like Royal Bank of Scotland, Citigroup or Bank of America’s before. Toyota, the most vaunted carmaker in the world, is seeking government assistance. It feels like Armageddon.

Amidst the carnage, analysts are singing a hopeful song over rising liquidity, in particular, China’s surging lending in the past two months. China’s stock market has outperformed other markets by over 40% since November last year. The surging lending and rising stock market have caught the eyes of investors around the world. On several occasions markets around the world rose or fell on their perceptions of what were happening in China. It shows how important China has become. Investors know that the next economic upturn, regardless of when and how, will have a lot to do with China. As the US may need years to repair its balance sheet and Europe and Japan are weighed down by aging populations, China seems the only hope to power the next upturn. This is why what occurs in China is affecting global markets.

The faith in liquidity, however, is misplaced. Liquidity took on mythical power during the Greenspan Era. Financial professionals spend numerous hours talking about it. Few, however, know what it really is. When a central bank says it is injecting liquidity. It buys some financial securities, e.g., government bonds, in exchange for cash. When it is done with the operation, its balance expands: on the liability side, it owes the financial system more money, on the asset side, it owns more securities. The changes in the balance sheet of the financial system are exactly the opposite: it has more money and fewer securities. With additional money, the financial system may be inclined to lend more or buy more securities. The former increases the borrowers’ ability to spend. The later lifts asset prices. Economists usually focus on the former, while financial professionals the later.

Liquidity became respectful through Keynes’s writings. It was synonymous with speculation before. He was primarily concerned about how to stimulate demand during frequent recessions in early 20th century. Liquidity was associated with fiscal stimulus, i.e., providing support for fiscal bonds to fund fiscal deficit. The main idea is that, when someone is unemployed, giving him something to do would be positive. Even if his work is totally useless, he would spend the income, which would lead to a chain reaction in creating useful economic activities. When an economy is unemployed, fiscal deficit will improve it.

In contrast, Joseph Schumpeter advocated recession as creative destruction-a cleansing process to weed out the weak and create room for new businesses. In this theory, boom-burst cycles are a sign of progress. Government interventions to ‘smooth’ the cycle may be counterproductive, e.g., suppressing innovations. The rising prosperity in the 19th century despite violent economic cycles seems to support this theory.

The world is not black and white like what the Keynesian or Schumpeterian theory suggests. When an economic downturn is severe, it could trigger social revolutions. The revolutions in the 1930s and 40s had a lot to do with the Great Depression. Keynes is right that governments have a responsibility to stimulate in a severe recession. But, stimulus doesn’t work in the long run. Governments must bear in mind that innovation is ultimately the source of economic growth. Dependency on stimulus may lead to stagnation. A recession could serve a useful purpose in shaking out the underperforming businesses.

During the stagnation of 1970s, liquidity as an ominous tool for economic management was discredited. Workers anticipated correctly the inflationary impact of monetary growth and demanded wage increase to offset inflation. The wage inflation immediately led to CPI inflation. There was a direct path between monetary expansion and inflation. Hence, central banks were just causing inflation without stimulating demand. The era ended when Paul Volker became the Fed Chairman and increased interest rate massively to tame inflation. His action laid the foundation for the low inflation era afterwards.

When Alan Greenspan became the Fed Chairman, the inflation expectation was low. When he increased money supply, it flowed into asset markets first. The resulting asset inflation boosted demand. It made his liquidity pumping highly effective in stimulating demand. The low inflation era was prolonged by globalization, as over one billion workers from the developing world entered the global economy. As Greenspan kept up his effectiveness, financial markets became used to the effectiveness of his liquidity policy. Most financial professionals came to worship liquidity as the silver bullet for reviving economies.

When the current crisis began in August 2007, central banks again created liquidity to deal with it. The faith in liquidity boosted confidence and stabilized financial markets for a few months. But, through 2008, it began to lose traction. The liquidity didn’t lead to rising asset prices or improving demand. Global economy and financial markets dived in a vicious spiral. Why hasn’t it worked this time?

Even though financial professionals often talk about liquidity like free money, it is actually short-term debt. It works when there are enough households or businesses that are willing to borrow to spend. When a debt bubble bursts, there are few entities that could borrow more regardless of how low interest rate is. Hence, liquidity doesn’t work in the aftermath of a debt bubble bursting. All that liquidity does is to build up in the financial system. In the jargon of monetary economics the money multiplier decreases with liquidity rising.

China’s situation is different from the western economies. It doesn’t have high leverage in general. In particular, the household sector doesn’t have much debt at all. This is why there is so much attention paid to China’s liquidity surge. It has the potential to turn into demand. However, China’s structural imbalance between the household sector and the government/business prevents it from turning into demand.

China’s current liquidity results from the huge trade surplus due to faster decline of imports than exports. As the central bank has not been issuing sterilization papers like before to mop up the surplus, the liquidity has built up in the banking system. The banks have lent some of the surplus liquidity to state-owned enterprises in the form of discounted bills. As the interest rate on such loans is very low, the state-owned enterprises could deposit the borrowed money without incurring significant cost and, sometimes, even pocket a small profit. The practice has rapidly expanded the balance sheet of the banking system from accounting perspective.

The lending, however, won’t turn into demand soon. Most industries, especially the capital intensive ones, face overcapacity. Steel industry, for example, may have 30% overcapacity. The ship-building industry is seeing massive defaults in orders. Many, if not most, shipbuilders are facing bankruptcy. Most property developers are not selling and, if given money to build more, would dig a deeper hole for themselves. China’s supply side has too much capacity. It is unlikely that more loans to businesses would spark an economic recovery.

Lending to government projects can support demand. It serves as a multiplier on the fiscal stimulus program. Bank lending may double its impact. The government has budgeted Rmb 1 trillion of fiscal deficit or 3% of GDP for 2009. The stimulus could stabilize the economy but not restart high growth. Exports and property were contributing 6-8 percentage points to GDP growth rate per annum in the last cycle and are now contributing a negative amount of similar magnitude. No amount of stimulus could completely offset the impact of their contraction. Further, China is already investing too much and shouldn’t push it excessively to pump up the economy temporarily and face a worse downturn later.

Export recession and the bursting of the property bubble are the sources of demand shortfall. The former is a consequence of the bursting of the global credit bubble. Globalization shifted production from developed to developing countries. The asset bubbles that western central banks tolerated during globalization allowed western consumers to defend their lifestyle with income extracted from asset bubbles despite the wage problem. As the bubbles bursts, their demand for exports from developing countries like China declines to what their wage could support.

China’s property market has been a bubble. In many cities the average price per square meter is three times average monthly salary or higher, while the amount of building is equivalent to one third of the existing housing stock. Such combination of high price and high volume is not sustainable. The strong demand before 2008 was a bubble phenomenon as buyers were betting on prices going higher or trying to lock in before the prices became out of reach.

To solve the demand weakness, China must boost household demand to offset export weakness and decrease property purchase cost to clear the existing inventory. China’s economy could not resume high growth without both issues addressed. Confidence is not the main reason for the relative weakness of China’s household demand. Low household income and wealth are. The quickest solution is to distribute the shares of listed state-owned enterprises that government holds to Chinese population. It will have a powerful short-term effect on consumption. As business profits improve in a booming economy, the shares appreciate, which further supports household demand and make the boom last.

In 1998, the government sold public housing flats to their tenants at notional prices, which laid the foundation for the housing boom afterwards. If China distributes the SoE shares to the household sector, it could ensure another decade of economic boom.

In terms of how to distribute the shares, the government can set up an account automatically for each Chinese citizen with his or her ID card number at one of China’s state banks. He or she could claim the asset at any branch of the designated state bank with his or her ID card.

Some argue that poor people who get the shares may sell them cheap. This happened in Russia in the 1990s. I don’t think Chinese people will behave the same way. China’s brokerage accounts are 10% of the population vs. 0.5% in Russia. It implies that Chinese people treasure stocks much more than Russians and would be careful in disposing them. Further, Chinese state-owned enterprises should distribute dividends together with the distribution of the shares. When people see the dividends, they will treasure the shares more. I suspect that the dividends will have a bigger impact on the economy than the SoEs spending the money on capex in overcapacity industries.

Others argue that the shares should be used to capitalize the social security fund. Lack of social security is a reason for the consumption weakness. But, I doubt that people would view the money in the social security fund the same way as the money in their pockets. Some studies in developed economies suggest that people discount each dollar in a government-controlled social security fund by 60%. Hence, it is much more powerful to put money into people’s pockets than in a government-run fund.

To clear the property inventory, the purchasing cost per square meter should decline to about 1.5 months of salary. This is not low by international standard. But, as China could sustain high economic growth for another 15 years or longer, the property price could be higher than the international average. The reduction of the purchasing cost probably needs to be shared evenly between price reduction and tax incentives. As China’s property market is so big, unless its health is restored, domestic demand would not likely resume robust growth.

Some hope liquidity would improve the economy through inflating asset markets, i.e., creating another bubble. This is what Greenspan achieved after the tech burst in 2000. Of course, his glory then has become today’s nightmare. Creating another bubble to deal with the consequences of the burst of a bubble is irresponsible even if it can be done. I doubt that it can be done in China today. Some of the liquidity did flow into the stock market in December 2008 and January 2009. At its recent peak the stock market rose by 40% in three months. But, it is extremely hard to manufacture a stock market bubble in a difficult economy. I cannot recall one in modern history. The reason is that speculators are quicker to take profits in a poor economy than in a booming economy.

Further, it is virtually impossible to inflate China’s property market by encouraging speculation, i.e., making funding easier to get and interest rate low. The current inventory is unprecedented by any measure. This is probably the biggest overhang per capita of physical properties completed or under construction in modern history. It would take three years to digest under the best policy combination. Re-inflating the bubble with liquidity is just a pipedream.

China’s problem is weak household demand. The reasons are low household income and wealth. Confidence is an issue but not the most important one. Strong exports in the past decade supported China’s massive investment. Now we urgently need household demand to replace exports to make the investment profitable. The quickest solution is to redistribute government wealth to the people. Focusing on liquidity only delays the solution and prolongs the hard economic time.
