Volcker is criticizing a decision to delay full implementation of a rule that bears his name and aims to curb banks' risky investments. The Fed said Thursday that it would delay until July 2017 the deadline by which U.S. banks will have to sell off potentially volatile holdings in private equity, venture capital and hedge funds.
