China's securities regulator suspended a new stock circuit-breaker after a sell-off forced local exchanges to shut for the second day this week, signalling that the country's leadership may reconsider or change the system.
The China Securities Regulatory Commission announced the suspension on its official microblog account on Thursday night. The decision came hours after CSRC officials held an emergency meeting to discuss conditions on the nation's tumbling stock market, according to a person familiar with the discussions who asked not to be named because he wasn't authorised to speak publicly.
China's CSI 300 Index plunged 7.2 per cent on Thursday, triggering an automatic shutdown within 30 minutes of the open, as declines in the yuan rattled investor confidence in the world's second-largest economy. The nation's market circuit breakers, which halt exchanges for 15 minutes after a 5 per cent drop in the CSI 300 and for the rest of the day after a 7 per cent retreat, have been criticised by analysts for exacerbating losses as investors scramble to exit positions before getting locked in.
China's threshold for trading halts looks "quite tight" versus circuit breakers in other markets, Deutsche Bank strategists wrote in a report this week. In the US, trading is halted temporarily after declines of 7 per cent and 13 per cent in the Standard & Poor's 500 Index, and only suspended for the rest of the day if losses reach 20 per cent.
Chinese regulators moved to ease one of investors' concerns earlier Thursday, imposing a new limit on the amount of stock that major corporate shareholders can sell. That followed intervention by government funds to prop up shares on Tuesday, according to people familiar with the matter.
Authorities are being forced to scale back efforts to let markets have more sway after an end to three months of relative calm on the nation's equity exchanges. Policy makers went to extreme lengths to support shares in the midst of a $US5 trillion rout last summer, including ordering stock purchases by state funds, suspending initial public offerings and allowing trading halts that froze hundreds of mainland-listed shares.
China's central bank is considering new measures to prevent high volatility in the exchange rate and will continue to intervene in the currency market, according to people familiar with the matter. Measures being considered aim to restrict arbitrage between onshore and offshore rates, the people said. The monetary authority didn't immediately reply to a fax seeking comment.
For Hugh Young, a managing director at Aberdeen Asset Management, China's efforts to intervene in the stock market are counterproductive.
"Often, the more measures the government takes, the more it encourages people to go against it," Young said. "They should regulate the market to make sure rules are clear and people abide by the rules. They shouldn't worry as stock prices go up or down."
