On the use of monetary and macroprudential policies for financial stability in emerging markets

  • F. Gulcin Ozkan
  • D. Filiz Unsal

This paper explores optimal monetary and macroprudential policy rules in an open-economy with significant exposure to external borrowing in the face of a sudden reversal of capital inflows. We consider optimal Taylor-type interest rate rules, where the policy rate is set as a function of inflation, output, and credit growth; and a macroprudential instrument is set as a function of credit growth. We have two key results. First, we find that, in the presence of macroprudential measures, there are no significant welfare gains from monetary policy also reacting to credit growth above and beyond its response to inflation. Thus, from a welfare point of view it is better to delegate ’lean against the wind’ squarely to macroprudential policy. Second, the source of borrowing (domestic versus foreign) plays a crucial role in the choice of policy instrument in responding to credit market developments. When the source of borrowing is external, monetary policy responses required to stabilize financial markets would be unduly large. In contrast, macroprudential instrument can directly influence the cost of credit and ease the fiancial markets. Therefore, emerging economies where foreign borrowing is typically sizeable are likely to find macroprudential measures particularly effective in promoting financial stability.
