The Bank of Japan announced a larger-than-expected economic stimulus measure that sent the Japanese yen lower against all its counterparts by 1.8 percent across-the-board.
The Bank of Japan governor Haruhiko Kuroda and his policy makers announced a surprise monetary policy to double its monthly bond purchases and adopted a two-year time frame to achieve their 2 percent annual inflation goal.
The BOJ board said that it will buy 7 trillion yen of bonds per month, exceeding the median estimate of 5.2 trillion yen. The BOJ also temporarily suspended a cap on some bond holdings and dropped a limit on debt maturities at the conclusion of its two-day meeting, the first to be led by Kuroda since he took office last month.
Dollar-yen rose sharply by 282 points to 95.67 from 92.85 while Euro-yen rose 345 points to 122.70 from 119.25.
