The Bank of Japan began a two-day policy meeting amid pressure from the country's new government to take more aggressive steps to fight the long deflationary slump in the world's third-largest economy.

The "Bank of Japan monetary policy decision could be a big moment for the country," said Colin Cieszynski, senior market analyst for CMC Markets Canada in a note.
"In recent weeks, (the yen) has been selling off and the Nikkei has been soaring on anticipation that the new government would get its way. Today the two markets are reversing course, suggesting either that traders expect the Bank of Japan won't go far enough or that significant stimulus has already been priced in and that some are already starting to take profits."
