Tokyo, March 22 (BridgeNews) - Bank of Japan Governor Masaru Hayami said that due to deflationary pressures arising both from the demand and the supply side it's too early to implement inflation targeting. Hayami added the BOJ will exercise caution on its outright purchases of government bonds, because if the central bank conducts outright purchases in such a way as to create expectations of inflation, trust in government bonds might be damaged.
