This paper surveys the literature on the effect of financial environment change on the monetary policy transmission mechanism, in particular, focused on the non-traditional transmission channels such as the credit and risk-taking channels. It seems that the existing studies before the Global Financial Crisis had shown that the credit channel became less effective, but the traditional neoclassical channels such as interest rate and foreign exchange channels became more effective due to the change in financial environment such as financial innovations and financial deregulation. However, after the recent Global Financial Crisis, we expect that, as the overall economic uncertainty grows and the global capital and liquidity regulations are introduced, the nontraditional transmission channels such as the importance of the credit and risk-taking channel will revive.
In particular, after the Global Crisis, the risk-taking channel has become more important as central banks consider aiming at achieving financial stability as well as price stability. According to the risk-taking channel, central banks need to prevent financial fragility by monitoring the aggregates such as banks’ liabilities in order to prevent banks’ excessive risk-taking.
