Macroeconomic effects of macroprudential policies: Evidence from LTV and DTI policies in Korea

This study investigates the effects of loan-to-value (LTV) and debt-to-income (DTI) policies on macroeconomic variables such as commodity price index (CPI) and industrial production (IP) and financial variables such as house price and household bank loan in Korea by employing a structural vector autoregression (VAR) model. We use measures of LTV and DTI regulations that properly reflect changes in regulation coverage and intensity. Empirical results show that LTV and DTI shocks have significant effects not only on house price and household bank loan but also on CPI and IP, particularly when both policies are implemented together. The effects of DTI shocks are similar to those of monetary policy shocks, but LTV and DTI shocks tend to have a slower effect on CPI and IP but a faster effect on house price and household bank loan.
