This note explores the signaling effect of foreign exchange market intervention in countries, such as Japan, the United Kingdom and the United States, where separate agencies are responsible for intervention and monetary policy. An important part of the signaling effect operates when an entity conducting intervention makes a credible commitment to a change in future monetary policy, suggesting that its effectiveness hinges upon whether the central bank is independent of government oversight. We test this conjecture by comparing the consistency of intervention and future monetary policy in Japan before and after April 1998, when central bank independence was established by the new Bank of Japan Law. As expected, the signaling effect of intervention weakened after the central bank became independent. |
