Monetary Policy Response on Exchange Rate Dynamics: The Case of Indonesia

Abstract

Bank Indonesia has been implementing Enhanced Inflation Targeting Framework (EITF) since few years ago. The main monetary instrument is short term policy interest rate. The policy interest rate, in this regard, may also have significant role in driving the exchange rate to its desired level. Setting appropriate the interest rate to drive the exchange rate is important to drive the actual inflation to its official target. In order to see the response of policy interest rate to exchange rate dynamics as well as the impact of exchange-rate dynamics to macroeconomic indicators, Structural Co-integrating Vector Auto Regression (SC-VAR) in an open economy model, is implemented. Its finding shows that exchange rate dynamic of USD/IDR has significantly positive relationship with domestic interest rate. The increase of the USD/IDR (depreciation) will then push domestic interest rate to increase.
