Since the floating system was introduced in 1973, there has been a controversy on the effects of foreign exchange market intervention and exchange rate policies.

During the mid-to late 1980s, there were a few cases of interventions among major currencies. The G-7 council generally coordinated these attempts. According to the Jurgensen report released by the G-7 council, 1) sterilized intervention which does not reflect the changes in the volumes currency, has a less effect on exchange rate compared with non-sterilized intervention which reflects those.
2) Sterilized intervention is effective to achieve the goal of short-term exchange rate policies. 3) However, sterilized intervention is ineffective on the long-term policy and can be offset by micro-economic policy. 4) A coordinated intervention based on agreement among country has a greater effect on foreign exchange markets compared with individual intervention.

However as the exchange rate of the yen and mark against to dollar has been appreciated since the Plaza agreement among the G-5 countries included the United States, Germany and Japan in 1985, the study on foreign exchange market intervention is in progress actively.
