Shanghai copper rises

Shanghai's most active April copper futures contract rose 1.3 percent to 71,700 yuan a tonne on Thursday. The Shanghai Futures Exchange will provisionally raise trading margins and intraday limits for all contracts around the Lunar New Year holiday, to lower trading risk.
The exchange said on its website that margin requirements on copper, aluminium, wire rod, gold and fuel oil contracts will be increased to 11 percent, from 10 percent currently, effective at the close of business on January 31.
