The Shanghai Futures Exchange (SHFE) plans to lower transaction fees for its rebar and copper contracts as well as to cut trading margins for its lead contracts from October onwards, a spokesman said on Tuesday.

Transaction fees for its rebar futures will be lowered to 0.006 percent from 0.01 percent, while fees for copper futures will be halved to 0.01 percent from Aug 1.

The exchange will also cut trading margins for lead futures from Oct to 8 percent from 11 percent with effect from July 29 settlement.
