Chinese Shares Tumble 8.5% in Biggest One-Day Drop Since 2007


Chinese shares tumbled more than 8 percent on Monday as an unprecedented government rescue plan to prop up valuations abruptly ran out of steam, throwing the viability of Beijing's efforts to stave off a deeper crash into doubt.

Major indexes suffered their largest one-day drop since 2007, shattering three weeks of relative calm in China's volatile stock markets since Beijing unleashed a barrage of support measures to arrest a slump that had started in mid-June.

"The lesson from China's last equity bubble is that, once sentiment has soured, policy interventions aimed at shoring up prices have only a short-lived effect," wrote Capital Economics analysts in a research note reacting to the slide.

The CSI300 index <.CSI300> of the largest listed companies in Shanghai and Shenzhen plunged 8.6 percent, to 3,818.73 points, while the Shanghai Composite Index <.SSEC> lost 8.5 percent, to 3,725.56 points.

Stocks fell across the board on Monday, with 2,247 companies falling, leaving only 77 gainers.

More than 1,500 shares listed in Shanghai and Shenzhen dived by their 10 percent daily limit, led by index heavyweights including China Unicom <600050.SS>, Bank of Communications <601328.SS> and PetroChina <600028.SS>.

All traded index futures contracts also fell by their maximum 10 percent limit, with the exception of a few tracking the large cap SSE50 index, which declined around 9 percent.

Analysts struggled to explain the severity of the sell-off, which accelerated sharply in the afternoon session, long after investors had time to digest the latest economic releases.

Markets had opened down more than 2 percent, following lackluster data on profit at Chinese industrial firms on Monday and a disappointing private factory sector survey on Friday.

But Chinese stock investors have been celebrating bad economic news for months on the basis it would provoke more aggressive policy easing, seen as positive for stocks because it pushes cheap money into the market.

Some saw the government-induced recovery in share prices in recent weeks as itself provoking the crash.

"After two weeks of steady rebound, both foreign investors and domestic institutions are gradually taking profits, increasing selling pressures," said Yu Jun, strategist at Bosera Asset Management Co.

"In addition, investor confidence hasn't fully recovered. There has been no obvious increase in outstanding margin loans, while the amount of fresh capital inflows is much lower than the average level in May and June. With not enough money taking up the baton, a renewed, sharp correction is inevitable."


China's main stock indexes had more than doubled over the year to mid-June, when a sudden swoon saw shares lose more than 30 percent of there value in a matter of weeks.

Markets finally began stabilizing again in the second week of July, due almost entirely to an all-out effort from Beijing to pump liquidity into the market while barring investors from selling off.

China's central bank cut interest rates, brokerages formed stabilization funds and regulators lifted restrictions on pensions and insurers investing in stocks, an implied combined total verbal commitment of almost $800 billion.

Beijing also cracked down on "malicious" short-sellers in the futures market, froze IPOs to prevent a liquidity drain and looked the other way as around 40 percent of companies suspended trading in their shares to escape the rout.

The campaign even acquired nationalistic tones at times, with local governments calling on retail investors to "defend the stock market" and domestic media and popular commentators expressing suspicions that the crash had been engineered by a foreign cabal.

Chinese share markets had recovered around 15 percent from their early-July trough before Monday's renewed sell-off.

However, analysts were sceptical of how long the campaign could be sustained, given the fright retail investors took at the speed and scale of a slump that wiped out as much as $4 trillion in stock market capitalization before Beijing grabbed the wheel.

Some analysts say the primary problem is that a market that rose so sharply on the expectations of aggressive easing from Beijing is seeing diminishing returns from future loosening, especially if the United States adapts its monetary policy.

"The main factor of today's fall is attributable to the uncertainty of the future monetary policy," said Du Changchun, stock analyst at Northeast Securities. "The rising CPI, particularly the rising pork price, has made it harder for the monetary authorities to roll out more easing measures."
