In a rare split decision, the BoJ’s board voted 5-4 to accelerate purchases of Japanese government bonds so that its holdings increase at an annual pace of 80 trillion yen ($725 billion), up by 30 trillion yen.
BoJ’s easing is being seen as an alternative to the U.S. Federal Reserve’s just concluded bond-buying programme, supporting the rally in emerging markets such as India, already underpinned by reforms and hopes of a rate cut.
“BOJ’s easing would further the argument of central bankers other then Fed providing stimulus to support economies and assets,” said U.R. Bhat, managing director at Dalton Capital, a unit of U.K.-based investment management firm Dalton Strategic Partnership LLP that manages nearly $2 billion in assets.
“I agree there are strong expectations of a rate cut. But there is no tax on expectations. Is it?”
