International evidence has shown how the lack of proper corporate governance in banks increases risk management, thereby reducing their financial strength. This paper addresses how corporate governance in Peruvian banks is related to their financial strength. The measure of corporate governance includes variables such as Board's compensations, shares concentration, transparency and market discipline. In turn, a measure of financial strength is built, including indicators of capital adequacy, asset quality, management, earnings, and liquidity. Most importantly, our results indicate that banks with higher corporate governance indices exhibit higher financial strength.
