Japan intervened to weaken the yen for the third time this year and pledged more sales after the currencyâs gain to a postwar high against the dollar threatened a recovery from the March 11 earthquake and nuclear disaster. The yen plunged more than 4 percent to 79.20 after authorities sold the currency in a unilateral intervention. Japanese Finance Minister Jun Azumi said the move was carried out to combat âone-sided speculative moves that donât reflect the economic fundamentals of our economy.â Azumi pledged to keep selling the yen in the foreign- exchange market after the currency reached a high of 75.35 against the dollar earlier today. It was the first yen-selling action by Japan since August. The yen and the Swiss franc have soared to records as investors sought havens from Europeâs fiscal debt woes. http://www.bloomberg.com/news/2011-...-mexican-cartel-said-to-be-dismantled-1-.html
