According to recent empirical studies, the new regulatory proposals concerning capital and liquidity standards as well as monitoring of global systemically important financial institutions may lead in a decline of the annual growth rates of GDP due to increase in lending rates and reduction of lending activities of commercial banks. At the same time, some studies show that the new measures may stimulate stability of financial system and help to reduce the probability of banking crises. This paper reviews the results of empirical studies on potential influence of new Basel III standards on functioning of the banking system, economic growth and financial stability.
