THE PRC'S CREDIBILITY?:

China's leaders appear to be terrified -- probably for political reasons -- by the prospect of even a brief recession. So they've been pumping up demand by, in effect, force-feeding the system with credit, including fostering a stock market boom. Such measures can work for a while, and all might have been well if the big reforms were moving fast enough. But they aren't, and the result is a bubble that wants to burst.

China's response has been an all-out effort to prop up stock prices. Large shareholders have been blocked from selling; state-run institutions have been told to buy shares; many companies with falling prices have been allowed to suspend trading. These are things you might do for a couple of days to contain an obviously unjustified panic, but they're being applied on a sustained basis to a market that is still far above its level not long ago.

What do Chinese authorities think they're doing?

In part, they may be worried about financial fallout. It seems that a number of players in China borrowed large sums with stocks as security, so that the market's plunge could lead to defaults. This is especially troubling because China has a huge "shadow banking" sector that is essentially unregulated and could easily experience a wave of bank runs.

But it also looks as if the Chinese government, having encouraged citizens to buy stocks, now feels that it must defend stock prices to preserve its reputation. And what it's ending up doing, of course, is shredding that reputation at record speed.

Indeed, every time you think the authorities have done everything possible to destroy their credibility, they top themselves.
