JPMorgan Chase & Co., Goldman Sachs Group Inc. and Bank of America Corp. won a delay of Dodd-Frank Act requirements that they wall off some derivatives trades from bank units backed by federal deposit insurance.

Commercial banks including the Wall Street firms may get as long as an additional two years — until July 2015 — to comply with the rules, the Office of the Comptroller of the Currency said in a notice yesterday. The provision was included in Dodd-Frank, the 2010 financial-regulation law, as a way to limit taxpayer support for risky derivatives trades.

The Commodity Futures Trading Commission and other regulators need to complete swap rules to allow “federal depository institutions to make well-informed determinations concerning business restructurings that may be necessary,” the OCC said in the notice. The so-called push-out provision of Dodd-Frank requires that equity, some commodity and non-cleared credit derivatives be moved — or pushed out — into separate affiliates without federal assistance.
