Politics In a marathon session of more than 21 hours, legislators agreed to a rewrite of Wall Street rules that may crimp the industry’s profits and subject it to tougher oversight and tighter restrictions. To secure agreement, lawmakers reached deals in the final hours on the most controversial sections which restrict derivatives dealing by banks and curb their proprietary trading to shield taxpayer-backed deposits from more risky activities. Banks will be allowed to keep most swaps dealing activity in-house, although the riskiest trading would be pushed out.
