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

Commercial banks including the Wall Street firms may get as longas an additional two years — until July 2015 — to comply with therules, the Office of the Comptroller of the Currency said in anotice yesterday. The provision was included in Dodd-Frank, the2010 financial-regulation law, as a way to limit taxpayer supportfor risky derivatives trades.

The Commodity Futures Trading Commission and other regulatorsneed to complete swap rules to allow “federal depositoryinstitutions to make well-informed determinations concerningbusiness restructurings that may be necessary,” the OCC said in thenotice. The so-called push-out provision of Dodd-Frank requiresthat equity, some commodity and non-cleared credit derivatives bemoved — or pushed out — into separate affiliates without federalassistance.
