Regulator douses fears over margin trading

CSRC says risks are 'still controllable' as stock prices slump

The securities regulator said on Friday that the risks presented by margin trading and banks using stocks as collateral were controllable, as it moved to allay investor concerns over potential forced liquidations, triggered by the recent steep market slide.

The statement came after the benchmark Shanghai Composite Index tumbled another 3.5 percent to close at 2,900.97 points, its lowest level in 13 months.
