Naked intervention, or unsterilized intervention, refers to the sole foreign exchange activity. All that takes place is the intervention itself, in which the Federal Reserve either buys or sells U.S. dollars against a foreign currency. In addition to the impact on the foreign exchange market, there is also a monetary effect on the money supply. If the money supply is impacted, then consequent adjustments must be made in interest rates, in prices, and at all levels of the economy. Therefore, a naked foreign exchange intervention has a long-term effect.
