China Tightens Margin Rules

Bloomberg: China Doubles Margin Requirement for Stocks to Curb Leverage

Margin requirements will be raised to 100 percent from 50 percent starting on Nov. 23, the Shanghai and Shenzhen bourses said in separate statements after local exchanges closed on Friday. The rule change means that an investor with 1 million yuan ($156,895) in their account is limited to borrowing another 1 million yuan from a broker to buy more shares. Previously, they could borrow as much as 2 million yuan.
