This study investigates the impact of the new capital requirements introduced under the Basel III framework on bank lending rates and loan growth. Higher capital requirements, by raising banks’ marginal cost of funding, lead to higher lending rates. The data presented in the paper suggest that assuming a 1.3 percentage point increase in the equity-to-asset ratio to meet the Basel III regulations, the country-by-country estimations imply a reduction in the volume of loans by an average 4.97 percent in the long run for the banks in countries that experienced a crisis and by 18.67 percent for the banks in countries that did not experience a crisis. The wide variance in the results reflects cross- country differences in the elasticity of loan demand with respect to loan interest rateand bank’s net cost of raising equity. Keywords: Basel III, capital requirements, banking performance GEL: C4, E44, E5, G21 1. Introduction Towards the end of 2008, it became clear that weaknesses in financial sector regulation and supervision had significantly contributed to the crisis. 1 University of Aegean, Business School, Dept. of Shipping, Trade &Transport, Chios, Greece.
