Authors: Anna Kovner and Peter Van Tassel

We estimate the cost of capital for the banking industry and find that, while the cost of capital soared for banks during the financial crisis, after the passage of the Dodd–Frank Act, the value-weighted cost of capital fell differentially more for banks than for nonbanks. The very largest banks drive the decline in expected returns, with some evidence indicating that stress testing has lowered the cost of capital for the very largest stress-tested banks. Changes to banks' cost of capital have real economic consequences-we find that increases in banks' cost of capital are associated with tightening in credit supply.
