Japan Central Bank Tweaks Monetary Policy 

Japan’s central bank tweaked its longstanding monetary easing programme on Tuesday, in a surprise move that saw the yen strengthen quickly against the dollar and prompted falls on Tokyo bourses. <br />The bank says it would widen the band in which it would allow rates for 10-year Japan government bonds to move, saying it would improve market functioning. <br />The Bank will expand the range of 10-year JGB yield fluctuations from the target level: from between around plus and minus 0.25 percentage points to between around plus and minus 0.5 percentage points. <br />The bank left the rest of its longstanding loose monetary programme intact, including its years-old inflation target of two percent.
