How bank capital buffers vary across countries: The influence of cost of deposits, market power and bank regulation

  • Fonseca, Ana Rosa
  • González, Francisco
Registered author(s):

    This paper analyzes the bank and country determinants of capital buffers using a panel data of 1337 banks in 70 countries between 1992 and 2002. After controlling for adjustment costs and the endogeneity of explanatory variables, the results show that capital buffers are positively related to the cost of deposits and bank market power, although the relations vary across countries depending on regulation, supervision, and institutions. Their impact is the result of two generally opposing effects: restrictions on bank activities and official supervision reduce the incentives to hold capital buffers by weakening market discipline, but at the same time they promote higher capital buffers by increasing market power. Institutional quality has the two opposite effects. Better accounting disclosure and less generous deposit insurance, however, have a clear positive effect on capital buffers by both strengthening market discipline and making charter value better able to reduce risk-taking incentives.
