This article explains the main features of the sterilized intervention in the foreign exchange market and the use of non-conventional policy instruments as applied by the Central Reserve Bank of Peru in order to avoid credit booms or busts in a context of a partially dollarized financial system. This monetary policy framework is based on a risk management approach that includes as the main policy tool the short-term interest rate within an inflation targeting regime. This framework helped to reduce the impact of the recent global financial crisis on the Peruvian economy and allowed to rejoin the path of growth with low inflation, avoiding major disruptions from the surge of capital inflows.
