Amends the Commodity Exchange Act to revise the requirement that the Commodity Futures Trading Commission (CFTC), before promulgating a regulation or issuing an order, consider the costs and benefits of the action. Requires the CFTC, through the Office of the Chief Economist, to: (1) assess the costs and benefits, both qualitative and quantitative, of an intended regulation; and (2) propose or adopt a regulation only on a reasoned determination that the benefits justify the costs.

Lists additional mandatory considerations for the CFTC to evaluate in making a reasoned determination of the costs and the benefits, including the impact on market liquidity in the futures and swaps markets, as well as alternatives to direct regulation.
