Noting uncertainty over the inflation outlook, board members agreed that the bank should continue with easing patiently to support wage increases, calling for flexible conduct of monetary policy, but also noted the need to continue debating the costs and benefits of the yield curve control framework.
At the September meeting, the BoJ policy board decided unanimously to maintain its monetary easing stance, keeping its zero to slightly negative interest rate targets along the yield curve as well as large asset purchases to continue seeking stable 2 percent inflation and support sustainable wage growth.
Governor Kazuo Ueda told a post-meeting news conference on Sept. 22 that the bank's policymakers"cannot possibly pre-determine the timing of policy change or specific responses," reminding that it may take some more time before clear indications for continued substantial wage hikes and stable 2 percent inflation emerge. He repeated that Japan's growth and inflation outlook remains highly uncertain.
Ueda also said the risk of under-easing is still greater than over-easing because Japan has experienced years of deflation and low inflation.
At its previous meeting in July, the board decided in an eight to one vote to make the bank's existing reference range for the 10-year bond yield more flexible, basically keeping the range of minus 0.5 percent to plus 0.5 percent, but expanded its ultimate defense lines to minus 1.0 percent and plus 1.0 percent in market operations. The July vote on the overall easing stance was unanimous.
By providing"greater flexibility" to its market operations, the bank hopes to avoid being forced to abandon the yield curve control policy framework when long-term interest rates come under persistent upward pressures. It also hopes to allow a natural uptick in long-term interest rates that reflects economic recovery with substantial wage hikes and mitigate the negative impact of artificially suppressing interest rates, which has paralyzed bond market functions and could negatively affect other financial markets.
The board remains cautious about making a fundamental change to the yield curve control framework, which was adopted in September 2016. A negative interest rate for the overnight rate was introduced in January that year.
Under the current framework, the BoJ is keeping the 10-year government bond yield, the benchmark for long-term borrowing costs, at around zero percent by buying"a necessary amount" of Japanese government bonds"without setting an upper limit," and to keep the overnight interest rate at minus 0.1 percent by charging 0.1 percent interest on a part of cash reserves parked at the bank by financial institutions.
