A Japanese Finance Ministry official said the government is ready to sell yen again following last weekâs move if it sees speculative trades driving the currency higher. Further intervention would âmaintain the effect and warn those who make unusual movesâ in the currency market, Vice Finance Minister Fumihiko Igarashi said on a television program of public broadcaster NHK yesterday. Japan sold yen in the foreign-exchange market last week for the second time this year to secure an economic recovery following the March earthquake and tsunami. Investors have been buying the currency as a haven from sovereign debt concerns in Europe and the U.S., which had its credit rating cut for the first time by Standard & Poorâs after markets closed on Aug. 5. http://www.bloomberg.com/news/2011-...en-selling-to-deter-currency-speculation.html
