The Bank of Japan’s nine-member policy board holds eight two-day Monetary Policy Meetings a year, in January, March, April, June, July, September, October and December. At each meeting, the board votes on the proposals on the bank’s monetary policy stance and the basic guideline on how to achieve the policy target submitted by the chair of the board, who is the bank governor. The board also votes on any proposals from other members. The first day of the meeting starts at 1400 JST and ends around 1600 JST. On the second day, the meeting begins at 0900 JST but no end time is set. It usually lasts for two and a half to three hours and can go on for a few more hours.

Markets can move going into each meeting on expectations for a shift in the bank’s policy stance or tweaking of policy tools. If the meeting lasts longer than usual, speculation for a possible change in policy may arise in the markets.
