The Shanghai Futures Exchange will raise trading margins and limits for all contracts from Nov 30 in a bid to curb speculative trading.

The move follows similar measures by China's other two big commodity exchanges, in Zhengzhou and Dalian.

The exchange said it would lift the margin requirement of copper, aluminum, steel wire, gold and fuel oil to 10 percent of the total value of the contract, while contracts for reinforced bar steel and zinc contracts will be increased to 12 percent.

Rubber contract margins would be lifted to 13 percent, it said on its website, adding that it would also increase the daily price move limits for all the contracts to 6 percent.
