US regulator looks to curb use of commodity ETFs and structured products following oil-price spike

Exchange-traded funds (ETFs) and structured products based on commodities could face serious restrictions as the US Congress and the Commodity Futures Trading Commission (CFTC) look to stop speculation. The CFTC will start hearings this month to set limits on the holdings of energy futures traders. The radical overhaul comes after the huge run-up in oil prices last year. Congress and the CFTC are determined to reduce volatility and bring rules on energy trading in line with other commodities.
