Persistent yen weakness near 160 against the dollar and July core CPI rising to 1.8% from 1.6% have reinforced expectations for further Bank of Japan normalization after the June hike to a 1% policy rate. Market-implied odds heavily favor a 25 basis point increase at the September 17-18 meeting, consistent with reports that officials view an early move as likely amid upside inflation risks from energy costs, imports, and AI-related demand. Government support for tightening to bolster the yen has added to the hawkish tilt. Upcoming speeches by Deputy Governor Himino and other board members ahead of the decision will test whether the BOJ accelerates its pace beyond the prior semiannual cadence, while no-change odds remain a distant second.

This market will resolve according to the change in basis points in the uncollateralized overnight call rate resulting from the September 2026 meeting of the Bank of Japan, relative to the level it was prior to this meeting.
The resolution source will be official information from the Bank of Japan, including the statement or release from its September 2026 meeting, scheduled for September 17-18, 2026, as listed on the official Bank of Japan calendar (https://www.boj.or.jp/en/mopo/mpmsche_minu/index.htm). This market may resolve as soon as the statement or release of the Bank of Japan’s September 2026 meeting with relevant data is issued.
If the specified rate is defined by an upper and lower bound, the relevant change will be the change to the upper bound.
If the specified rate is changed to a level not expressed in the displayed options, the change will be rounded according to the following guidelines. Increases or decreases of less than 25 bps will be rounded to 25 bps (e.g. an increase or decrease of 10 bps would be considered to be an increase or decrease of 25 bps). Increases or decreases of greater than 25 bps will be rounded to the nearest 25 bps and will be rounded away from 0 in cases of equidistance (e.g., an increase or decrease of 37.5 bps would be considered to be an increase or decrease of 50 bps). Displayed options of “Increase” or “Decrease” will include policy rate increases or decreases of any size.
If the specified meeting is postponed to a date and time before the start of the next scheduled meeting, this market will resolve based on the outcome of that postponed meeting. If the specified meeting is cancelled, or postponed such that no decision is announced by the start of the next scheduled meeting, this market will resolve to the “No Change” bracket.
