Bank of Japan Deputy Governor Hirohide Yamaguchi pledged âdecisiveâ policy action when needed as Europeâs sovereign-debt crisis poses greater risks to the global economy. The BOJ will âtake appropriate policy actions in a flexible and decisive mannerâ if necessary, Yamaguchi said today in a speech in Nagano, central Japan. âThe bank is aware that uncertainties at home and abroad are significant.â The International Monetary Fund yesterday recommended that the BOJ support the economy by increasing its asset purchases, its main policy tool. The yen rose to a four-month high of 78.47 against the dollar last week on concern Europeâs sovereign-debt crisis will spread and Yamaguchiâs comments signal the BOJ can act even after Governor Masaaki Shirakawa expressed increased optimism about the nationâs recovery from the March 11 earthquake, according to analyst Mari Iwashita. âThis is a pretty dramatic change given that Shirakawa provided a relatively sanguine view on the economy just a week ago,â said Iwashita, chief market economist at SMBC Nikko Securities Inc. in Tokyo. âI donât think the BOJ is considering taking action now but the comments indicate the BOJ will take action when the European debt crisis begins to take a significant toll on Japanâs stocks and the yen.â http://www.bloomberg.com/news/2011-...e-policy-action-if-needed-deputy-says-1-.html
