Four consumer advocacy groups are calling on federal banking regulators to provide for an additional 90 days for the public to comment on proposed changes to the Volcker Rule. In a July 10 letter to five agencies, Better Markets, Americans for Financial Reform, Public Citizen and the Center for American Progress argued that the 60- day public comment period is "inadequate given the rulemaking's length, complexity, and importance and is inconsistent with the Administrative Procedure Act." In contrast, they point out that the agencies afforded a 40-month period for public engagement prior to enactment of the original Volcker Rule in 2014. The five agencies – the Fed, FDIC, OCC, SEC and CFTC – rolled out the 373-page proposed rule to simplify and relax some of the Volcker Rule's restrictions on proprietary trading by financial institutions on May 30.
