The Federal Reserve will vote next week to finalise capital rules for US banks after regulators agreed to resolve a separate issue that had delayed action.

After months of dispute, officials at the Fed, Federal Deposit Insurance Corp. and Office of the Comptroller of the Currency have agreed to increase one measure of the biggest banks' ability to operate in times of stress. Banking regulators will soon propose requiring banks to increase the amount of equity they hold against assets, known as the "leverage ratio."
