The Bank of Japan Policy Board on Friday left its monetary policy unchanged for the month and decided to introduce by the end of May a measure to stabilize the government bond market.

After a two-day meeting, the board agreed to maintain continuous liquidity in the financial market to support the nation's economic recovery and to fight deflation.

As a benchmark for its easy monetary policy, the nine-member board decided unanimously to keep its target for the outstanding balance of banks' deposits at the central bank within a range of 30 trillion yen to 35 trillion yen.
