TOKYO (Reuters) - The Bank of Japan shocked markets on Thursday with a radical overhaul of its policymaking, adopting a new balance sheet target and pledging to double its government bond holdings in two years as it seeks to end nearly two decades of deflation.
At new Governor Haruhiko Kuroda's first policy-setting meeting, the central bank shifted its monetary policy target to the monetary base from the overnight call rate, which is set at a range of zero to 0.1 percent.
The unexpected scope of the changes Kuroda pushed through drove the yen lower and knocked the 10-year bond yield to its lowest in a decade.
"The BOJ will conduct money-market operations so that the monetary base will increase at an annual pace of about 60 trillion yen to 70 trillion yen ($645 billion to $755 billion)," the central bank said in a statement announcing the decision.
It also combined two bond-buying schemes, its asset-buying and lending program and the "rinban" bond-buying market operation, to buy government bonds across the yield curve including those with duration of 40 years.
The BOJ will revert to open-ended asset purchases and buy over 7 trillion yen ($75 billion) of long-term government bonds per month, so that the balance of its bond holdings increase at an annual pace of 50 trillion yen, the central bank said.
The central bank will also increase purchases of exchange-traded funds (ETF) by 1 trillion yen per year and real-estate trust funds (REIT) by 30 billion yen per year.
