Estimating the effects of FX-related macroprudential policies in Korea

This paper provides an empirical assessment of the effects of FX-related macroprudential policies introduced in Korea since 2010. Our main findings are as follows. First, Korea's recent FX-related macroprudential measures have been effective in curbing excessive capital inflows. In particular, these measures have contributed to mitigating FX market vulnerability. Second, the leverage caps had a relatively larger dampening effects on short-term foreign borrowings of foreign bank branches compared to those of domestic banks. By contrast, macroprudential stability levy has worked as a device to limit foreign borrowings for domestic banks, but not for foreign bank branches.
