The Commodity Futures Trading Commission has voted to limit speculative trading for agricultural commodities, including corn, wheat and soybeans, according to the American Feed Industry Association

Part of the Dodd-Frank Act, the new rules establish speculative position limits on futures and swaps, and clarify rules for derivative clearing organizations. The CFTC will also review the limits every two years and can make adjustments if necessary. Overall, the limits will apply to 28 commodity futures. The CFTC estimates the limits will affect 84 traders of certain agricultural contracts. They will go into effect 60 days after CFTC defines “swap.”
