The Bank of Japan has not set a time limit on its ultraloose monetary policy, BOJ Gov. Haruhiko Kuroda said Monday, hinting that large-scale easing may be kept intact beyond its current policy effect projection up to the end of 2014.

While the BOJ gives figures for the outstanding amounts of the monetary base and government bond holdings as of the end of this year and next year, "these are projected amounts under the current policy and do not suggest in any way a time limit of the policy conduct," Kuroda said in a speech in Nagoya.

He vowed that the BOJ will continue with its large-scale monetary policy to achieve an inflation target of 2 percent "as long as it is necessary for maintaining the target in a stable manner."
