BEIJING (BLOOMBERG) - China's securities regulator banned major shareholders, corporate executives and directors from selling stakes in listed companies for six months, the latest effort to stop the nation's US$3.5 trillion (S$4.7 trillion) stock-market rout.
Investors with stakes exceeding 5 per cent must maintain their positions, the China Securities Regulatory Commission said in a statement. The rule is intended to guard capital-market stability amid an "unreasonable plunge" in share prices, the CSRC said.
While China has already ordered government-owned institutions to maintain or boost their stock holdings, the CSRC's directive expands the ban on sales to non-state companies and potentially foreign investors who own major stakes in mainland businesses.
China has unveiled new market-boosting measures almost every night over the past 10 days, steps that have so far failed to revive investor confidence. Foreign traders have been selling Chinese shares at a record pace this week in part due concerns over the government's meddling in markets.
"This is not something would happen in the U.S. or in any other developed market," said Brian Jacobsen, who helps oversee US$250 billion as the chief portfolio strategist at Wells Fargo Funds Management. "It does smell a little bit of desperation. But in China it's a very unique system and they are taking unique steps to try to stop the drop."
The Shanghai Composite Index slid 5.9 per cent on Wednesday as official attempts to stop the selling, including measures to prop up small-cap stocks, were overshadowed by data showing an unprecedented liquidation of margin trades on Tuesday.
Chinese authorities have also suspended initial public offerings, restricted bearish bets via stock-index futures and encouraged financial firms to buy shares. In perhaps the most dramatic effort to prevent investors from selling, local exchanges have allowed at least 1,331 companies to halt trading in their shares.
As the Shanghai Composite's record-breaking boom goes bust, President Xi Jinping's government is intervening in an attempt to prevent falling stock prices from eroding confidence in his leadership. The moves have cast doubt on the ruling Communist Party's pledge less than two years ago to give market forces a bigger role in the economy, part of its largest reform drive since the 1990s.
China isn't the only market with a history of state intervention. During the Asian financial crisis in 1998, Hong Kong's government bought shares worth US$15 billion to prop up the market. In the U.S., the Securities and Exchange Commission temporarily banned short selling on some shares during the global financial crisis in 2008.
MSCI Inc., whose indexes are used to benchmark an estimated US$9.5 trillion of assets, cited China's capital controls as a reason why mainland shares were left out of its global equity gauges in June.
Foreign investors have sold a net 33.4 billion yuan (S$7.3 billion) of Shanghai shares through the city's exchange link in the past three days. China has allocated investment quotas of about US$138 billion through its so-called QFII and RQFII programs for foreign money managers, which include BlackRock Inc. and HSBC Global Asset Management.
"The extent to which they can apply this to foreign ownership interest remains to be seen," Mr Jacobsen said. "But to me they are grasping the straws to find a way to stop the selling pressure."
