On Thursday China's mainland markets were the main losers in Asia, as worries over tighter requirements on margin financing spurred selloff.
Separately, filings signaled that China Central Huijin Investment Ltd., a unit of China's sovereign wealth fund China Investment Corp. (CIC), cut its stakes in the country's biggest state-owned banks for the first time.
On Thursday China's key Shanghai Composite declined 6.5 percent to 4,620.27, marking its biggest one-day loss since January 19 and
breaking an eight-session winning streak.
The CSI 300 index of the largest listed companies in Shanghai and Shenzhen tumbled 6.7 percent, while the start-up board ChiNext sank 5.4 percent.
Local media reports said the filings to Hong Kong Exchanges &
Clearing showed that China Central Huijin sold 300 million
Shanghai-listed shares of Industrial and Commercial Bank of China Ltd.
(ICBC)
and 280 million Shanghai-listed shares of China Construction Bank Corporation on Tuesday, for a combined
amount of over 3.5 billion yuan ($560 million), MarketWatch reported.
In Shanghai, financial stocks suffered a huge selloff, with China Construction Bank Corporation, ICBC, Agricultural Bank of China and Bank of China Ltd. all losing more than 5%.
The selloff was also driven as in recent days several brokers tightened up their margin-financing rules, including increasing the amount of cash clients must put down for their deposits.
