Abstract: Currency manipulation refers to a country’s interfering with the market’s determination of the exchange rate of its currency in order to influence its trade balance, usually to favor its exports over its imports. In a world in which people and firms trade and invest across borders, i.e. our world, anything a country does (monetary policy, fiscal policy, industrial policy, trade policy) will potentially affect the exchange rate of its currency for other currencies (real and/or nominal exchange rates). This makes it difficult to define what currency manipulation might mean, but it generally refers to a government’s intervention in the foreign exchange market by buying dollars or other foreign currencies thus depreciating its own currency’s exchange rate. This makes its exports cheaper to foreign buyers and its imports more expensive domestically resulting in a trade surplus (or smaller deficit). In the following I compare policy reactions to shocks under three types of exchange rate/monetary policy regimes with an eye on the currency manipulation question. The broad categories of shocks are a) a globally shared recession and b) a single country shock to imports or exports such as from an oil price shock or tariffs, or from changes in capital inflows or out flows such as from a change in the political environment. The three policy regimes are: 1) freely floating exchange rates with no restrictions on capital flows, 2) an adjustable exchange rate peg, and 3) a gold standard with currency board rules. Regimes 1 and 3 are the opposite ends of the range of policy regime options. A strict gold standard (or other hard anchor) with currency board rules removes any question of currency manipulation as it is not possible in such a regime.
