In January, Xiao summed up China’s stock market problems: an “immature bourse and participants, incomplete trading rules, an inadequate market system and an inappropriate regulatory system”. That pretty much covered things, except the real causes of the market rout: overvalued stocks, an overleveraged, slowing economy with excess capacity and little hope for consumer spending to take up the slack. January’s massive issuance of new bank debt would seem to indicate that Beijing is less optimistic than it’s saying about consumption replacing investment in our lifetime.

Xiao’s last straw was the spectacular failure of his signature solution to stop the market meltdowns that began last summer: circuit breakers. Circuit breakers have been around since 1988, when the Brady Commission recommended them as a means to temporarily halt relentless selling by institutions so buyers had time to gather and come back into the markets. I spent that spring in a class taught by a senior staff member of the commission, which identified the causes of the October 1987 “Black Monday” crash and fixed them.
The start of the decline “ignited mechanical, price-insensitive selling by a number of institutions employing portfolio insurance strategies and a small number of mutual fund groups reacting to redemptions. The selling by these investors, and the prospect of further selling by them, encouraged a number of aggressive trading-oriented institutions to sell in anticipation of further market declines... This selling, in turn, stimulated further reactive selling by portfolio insurers and mutual funds,” it found.

A regulator’s job isn’t to keep markets up, though. It’s to keep them clean and functioning properly
Which is exactly what happened on January 7, the second and final day of the circuit breaker’s short life. The ticker was in relentless free fall, wiping out billions in market valuation in just 14 minutes of trading.
