The purpose of this study is to provide the diagnosis of the global financial crisis and the assessment of the accomplished financial policy in Korea after the collapse of Lehman Brothers Investment Bank. This global financial crisis was triggered by the fallout of the US sub-prime mortgage meltdown, which is ongoing worldwide. There was no exception on Korea to avoid its turmoil. It was for this reason that the funds flowed out due to de-leveraging by international financial institutions in response to heightened concerns about credit crunch. Real economy also went to recessions due to rapid export slowdown accompanied by the contraction of import demand from other countries. Korean government planned to support banks by establishing a bank recapitalization fund of 20 trillion won($2.8 billion). However, this plan was not fulfilled, because government didn't maintain policy consistency. The point is that the government must consider a policy consistency before using other funds such as restructuring fund and financial stability fund.
