A street sign stands outside the New York Stock Exchange on Wall Street in New York in this file photo taken August 19, 2011. Wall Street is ramping up a campaign against rules that are designed to prevent financial firms from being too interconnected, arguing that the well-intended regulations could backfire and hurt markets. The rules, which limit financial institutions from having too much exposure to any one party, have not grabbed nearly as much attention as the Volcker rule. But Wall Street banks fear they could hurt their profits as much - if not more. REUTERS/Lucas Jackson/Files (UNITED STATES - Tags: BUSINESS) Published: Čer. 25, 2012, 7:14 odp. | Foto: Reuters
