The U.S. Treasury Department on Thursday kept Japan and six other economies on a monitoring list over potentially unfair currency practices and called on Tokyo to ensure any necessary market interventions are well-coordinated.
Referring to Japan's yen-buying, dollar-selling intervention in September in a semiannual report to Congress, the department said interventions should be reserved "only for very exceptional circumstances with appropriate prior consultations."
The department did not criticize the intervention, which temporarily lowered the value of the U.S. dollar against the yen, and said, "Japan is transparent with respect to foreign exchange operations, regularly publishing its foreign exchange interventions each month."
Apart from Japan, the other economies kept on the list were China, Germany, Malaysia, Singapore South Korea and Taiwan. India and Vietnam were on the list in the previous report released in June, but removed this time.
The report criticized China for lacking transparency with regard to its currency market interventions and foreign exchange mechanisms.
"Treasury will continue to closely monitor China's use of exchange rate management, capital flow, and regulatory measures and their potential impact on the exchange rate," the report said.
