<p>WASHINGTON—All five regulatory agencies put to a vote and approved the Volcker rule on Tuesday, ushering in a new era of tough oversight that drills to the core of Wall Street's profitable markets and trading businesses.</p>
<p>The rule will put in place new hurdles for banks that buy and sell securities on behalf of clients, known as market making, and will restrict compensation arrangements that encourage risky trading. The Fed also approved an extension to give banks until July 2015 to comply with the rule, though firms will be expected to make "good faith" efforts to get into compliance earlier.</p>
