Macroprudential policies as buffer against volatile cross-border capital flows

This paper investigates the effectiveness of macroprudential policies introduced by Turkey in late 2010. The unprecedented quantitative easing policies of advanced countries after the global financial crisis have presented serious financial stability concerns for most emerging countries including Turkey. To cope with these challenges, Turkey has devised new policy tools such as asymmetric interest rate corridor and reserve option mechanism. From the perspective of capital flows, the interest rate corridor works mainly through stabilizing supply of foreign funds, and the reserve option mechanism through decreasing the sensitivity of equilibrium exchange rate to shifts in the demand for foreign funds. Using a large panel of 46 countries and employing [Bruno and Shin (2013a). Capital flows, cross-border banking and Global liquidity. Working paper, Princeton university; Bruno and Shin (2013b).

The results show that, after controlling for a set of domestic and external variables and relative to a group of advanced and emerging countries, cross-border capital flows to Turkey have been less sensitive to global factors after the implementation of macroprudential policies.
