Bank run in Hong Kong

What was supposed to be largely a US financial crisis seems to be spreading even further.  This might come as both a surprise and an annoyance to those who believe that the cause of the crisis was specific mistakes made by US bankers and regulators, but much less of a surprise to those who assume that runaway monetary expansion always leads to very risky and vulnerable financial systems, and the list of countries that have tolerated or even exacerbated runaway monetary expansion is a very long list.

Here in China, in sympathy with the weirdness abroad, the stock market is still racing around erratically.  On Wednesday the market bounced up and down violently several times before ending the day with the SSE composite up 15 points, or 0.7%.  Today, prices surged 5.3% within two hours of opening, and then gave some of it back to close at 2297, up 3.6%.

The market surged, according to Bloomberg, “after the country’s two exchanges eased restrictions on equity buying by controlling shareholders and on speculation government-run investors increased purchases,” although I think the bank share purchases have been, fortunately, quite small (an article in today’s Xinhua stated that the net purchases of shares by Central Huijin in the three big banks amounted to increases in ownership of well under 0.001%).  The Bloomberg article extlink_3.gifgoes on to say:

Under new rules taking effect today, the period in which controlling shareholders are barred from raising their stakes in publicly traded companies has been cut to 10 days before earnings are released, from 30, according to statements from the exchanges.  China’s state-owned companies should be “a role model” in promoting “stable” development of the nation’s capital markets by buying back shares in publicly traded units, the State-owned Assets Supervision and Administration Commission said Sept. 18.

Aside from the fact that to be a “role model” these days is pretty narrowly defined (you must simply buy shares), my former students in the market tell me that there is also serious speculation that securities rules will be changed to allow shorting and margin investing.  Although I am not sure either of these measures is likely to add stability in what is a highly speculative market (on the contrary), to some extent these rumors are more of the same old stuff.  Basically what is driving the market is government intervention and government signaling.

Given how chaotic and dangerous markets have been recently, this is probably as good a time as any for market intervention, and certainly Chinese policy-makers are not the only ones around the world who think so, but investors here have been so conditioned to think of the market’s performance as almost exclusively a function of government behavior that I am afraid that the impact of the latest round of activity in China will be far more ephemeral than it might be in other markets.  Once investors perceive that the government has run out of ammunition or new tricks to spur the market, prices will plunge.  Once the market stops surging, it will very quickly lose its legs as investors pile out waiting for the next bag of tricks, and we’ll soon be testing the lows again.

More interesting to me than the stock market were events in Hong Kong concerning the Bank of East Asia.  After several days of rumors and speculation, long lines of depositors are now lining up at the bank desperate to take their money out – and have been so since late last night.  Deposit withdrawals actually began on Tuesday, but only really picked up steam last night.  Bloomberg says this is Hong Kong’s first bank run since the Asian Crisis of 1997, but the South China Morning Post lists the last bank run as BCCI in 1991.

The chairman of the bank, David Li Kwok-po, is apparently furious at what he calls “groundless” rumors about solvency problems at his bank and he and Hong Kong regulators are loudly proclaiming that the bank is perfectly safe, but, whether they are telling the truth or not, this is the way bank runs work.  There is no strong incentive for depositors to trust the safety of the bank, beyond their giving up a few days of (low) interest, and every incentive for them to flee to safety.  Even if every one knows that the bank is safe, simple game theory suggests that once the process starts, until something happens to signal that the game is over it makes sense to withdraw deposits.  More ominously, two other local banks, DBS and Dah Sing, are also now subject to rumors.  By the way there is an interesting article extlink_3.gifon the subject in today’s South China Morning Post, which also has a brief history of Hong Kong bank runs.

Interestingly enough, according to today’s South China Morning Post, one of the factors in the bank run was the wide diffusion of mobile phone SMS and BBS postings warning that there was trouble in the bank.  There was also a seemingly unrelated news story extlink_3.gifin the same newspaper about the closing down for three months of China Business Post, “one of the oldest financial newspapers on the mainland,” for a “scathing” report in July on Agricultural Bank of China.  Apparently the newspaper received an unexpectedly harsh punishment for reporting a story about fraud at ABC, which was later denied by the bank.  Why such a harsh punishment?  Could it be that authorities are worried by negative articles about mainland bank practices?

Regular readers of my blog know that I am always interested in the phenomena of bank runs.  They almost always come as a shock to places and institutions where only a short while earlier most people would have considered them inconceivable.  But the more overextended a bank’s balance sheet is, the smaller the shock needed to cause a sudden contraction, and as Nassim Nicholas Taleb has pointed out several times extlink_3.gif– often a little grumpily – these are not events whose probability can be statistically modeled in a meaningful way.  Under current conditions, we can only say that unexpected events like bank runs should not be considered unlikely.  This obviously has implications for the Chinese banking system – which actually experienced bank runs not so long ago, earlier in this decade.

And implications also for the country’s currency regime.  A lot of people have been asking me recently about China’s strategy for the RMB.  Should China continue forcing the RMB up, or is it time to change strategy?  Given the possibility of slower export sales, might we even see depreciation?

I have never believed that the purpose or RMB appreciation was directly to rebalance trade.  For several years China needed to revalue the yuan not to reduce the trade surplus but rather to regain control of its monetary policy.  If it was able to regain control, the trade surplus would automatically decline anyway because what was pumping exports was the surge in industrial production caused by the channeling of China’s money growth into the banking system – fueled at first, in a self-reinforcing feedback loop, largely by the impact of the trade surplus on reserve accumulation.

At first the main source of money inflow was the trade surplus.  While this continues to be large, in the last year it has been speculative inflows that have driven reserves up.  China’s currency regime needs sharply to reduce the latter and to bring the former to a more reasonable level. Until the now it seemed to me that the only way to do so was to engineer a maxi-revaluation.  But there are four things that can, in principle, reduce the need to revalue, although all of them, one way or another, create problems for the economy.

1.If global growth slows sharply, China’s trade surplus is likely to decline.  This will reduce the impact of the trade surplus on reserve accumulation and so slow money growth.  A reduction in the trade surplus might not be enough by itself to allow the PBoC to regain control of monetary policy, but if slowing export growth leads to slowing economic growth, which then also reduces capital inflows, it might be more than enough.

2.If the prospects for asset appreciation (including currency appreciation) decline, speculative inflows will slow or even reverse, thus removing the biggest recent source of unstable growth in reserve accumulation.  This means that when investors expect lower returns from their Chinese investment, the incentive to bring money into the country to invest will, of course, decline.

3.If the currency is forced to appreciate surreptitiously via a surge in inflation, China can eventually reduce net inflows once the currency is perceived to be overvalued and expectations of a Vietnam-style depreciation set in – but of course in that case China will have anyway achieved everything it was hoping to avoid.

4.Most dangerously, if the perception of risk in the financial system (or anywhere else in the economy, for that matter) rises, investors will begin to exit, and the worse the perception of risk that faster the exit.  At some point it even becomes self-reinforcing, as fleeing investors force an uneven contraction of the money supply, this exacerbating risk.  Unfortunately it is exactly the uncontrolled growth of money in previous years that would create the conditions for a surge in the perception of risk, by causing serious overextension in the country’s formal and informal financial systems.  This was always, in my opinion, the strongest reason for a maxi-revaluation: get monetary policy under control before the banking system became too risky

5.Of course the fifth option, which is the one I had always supported, is that China revalue the RMB substantially (and in one maxi-revaluation) to reduce or even reverse capital inflows and, by reducing the consequent monetary growth, eventually slow industrial production.  This was never going to be a painless option, but I expected that if China waited too long it was likely to see either #3, a surge in inflation, or #4, a breakdown in the financial system.  It may be too late to take that option – certainly under current conditions it would be very difficult.

It seems to me that we may be seeing all of these things happen at once.  It is too early to say, of course, but it is pretty easy to construct a plausible scenario where the US and Europe reduce their imports substantially (so reducing or even reversing China’s export growth), investors both expect lower returns in China (the pressure for currency appreciation declines) and see higher risk in the banking system.  Whether this is accompanied by inflation or not will depend on the actions of the PBoC and on how robust and stable the financial system is, but either outcome is pretty negative.

The outlook is worrying.  I guess I generally try to achieve a balance between expressing my deepest worries about the banking system and being excessively alarmist in public, and this has been a particularly difficult balancing act in recent weeks, but every week it seems the banking crisis steps into yet another market.  Where will it go next?

    Thank you Prof. Pettis for allowing RGE Monitor to post your work here. Pardon my ignorance on this subject, but has the Chinese gov’t made statements on their expectations/desires regarding what the US financial bailout should address or accomplish?

    It’s not surprising the the CNBC pimps for Goldman Sachs would be pushing for Paulson’s bankster bailout. It has gotten to the absurd point that the US Treasury will be sending multi-billion dollar Corporate Welfare checks to Goldman Sachs monthly. General Electric owns CNBC, but CNBC is operated as the Ministry of Propaganda for Goldman Sachs. With only the exception of Rick Santelli from Chicago, the rest of the motley crew of CNBC financial analysts are on the Goldman Sachs payroll.Beware on any stock market tips by CNBC financial analysts. Goldman Sachs alumni Jim Cramer was pushing Bear Sterns stock two days before the bankruptcy.
