This market resolves based on official monetary policy statements published on the Bank of Japan website following its October 2026 meeting. The target metric is explicitly defined as the change in the upper bound of the short-term policy interest rate compared to its level prior to the meeting. The rules clearly specify how non-standard changes will be handled via rounding up to the nearest 25 basis points bracket. Additionally, there is a clear fallback condition resolving to 'No change' if no official statement is issued before the subsequent monetary policy meeting concludes.

Resolution rules

The Statement on Monetary Policy for the Bank of Japan's Monetary Policy meeting for October is scheduled to be released on October 30, 2026 (https://www.boj.or.jp/en/mopo/mpmsche_minu/index.htm). This market will resolve to the amount of basis points the upper bound of the short-term policy interest rate is changed by versus the level it was prior to the Bank of Japan's October 2026 meeting. If the short-term policy interest rate is changed to a level not expressed in the displayed options, the change will be rounded up to the nearest 25 and will resolve to the relevant bracket. (e.g. if there's a cut/increase of 12.5 bps it will be considered to be 25 bps) The primary resolution source for this market will be the official website of the Bank of Japan (https://www.boj.or.jp/en/mopo/mpmsche_minu/index.htm), however a consensus of credible reporting may also be used. This market may resolve as soon as the Bank of Japan's statement for the specified meeting with relevant data is issued. If no statement is released by the end date of the next scheduled meeting, this market will resolve to the "No change" bracket.

Market explained

This market measures whether the Bank of Japan increases the upper bound of its short-term policy interest rate by 50 or more basis points following its October 2026 meeting, with rate changes rounded up to the nearest 25 basis points if not explicitly listed.

How it resolves

The market resolves to Yes if the Bank of Japan raises the upper bound of the short-term policy interest rate by 50 basis points or more compared to the pre-meeting level. Any interest rate change not expressed in the displayed options is rounded up to the nearest 25 basis points (for instance, a 12.5 bps change counts as 25 bps). The market resolves to No if the rate change is less than 50 basis points or if rates are cut or unchanged. If no policy statement is issued by the end date of the next scheduled meeting, the market resolves to the 'No change' bracket. Resolution is determined by the official Bank of Japan website or a consensus of credible reporting.
