International discussions on introducing a bank levy have centered on levies tailored for country-level circumstances and with the intention of protecting taxpayers and reducing systemic risk. This approach needs to be taken in Korea as well. Measures must both be able to contribute to domestic financial system stability, while minimizing the burden placed on financial institutions. A resolution fund-type contribution is not greatly needed at the current point in time given that it would overlap with similar existing regulatory schemes such as the financial stabilization fund. A contribution to stabilize the FX funding market should be considered as a means of moderating financial institutions' external debt and placing a portion of the costs of maintaining foreign reserves on the financial institutions that are the beneficiaries of such reserves. The formation of a fund can be used as a second line of defense for the stabilization of the FX funding market, performing a complementary function alongside official foreign reserves, separate from the exchange equalization fund.
