A new paper analyzes the cost of capital for banks during the financial crisis and in relation to the Dodd-Frank Act and Graham-Leach-Bliley Act. “We find some evidence that stress testing has lowered the cost of capital for the largest stress-tested banks, although not for those added more recently to stress testing,” say the authors, who are with the Federal Reserve. The paper is titled “Regulatory Changes and the Cost of Capital for Banks,” and you can download it here.
