Bank of Japan Decision in July?

Platform comparison

Market context

The Bank of Japan is set to announce its monetary policy decision on 31 July 2026, determining whether the upper bound of its short-term policy interest rate changes from the prior level. This market resolves to the basis-point adjustment, with any non-standard change rounded up to the nearest 25bp bracket. Current crowd-implied probability sits at 0% for a rate increase, suggesting traders expect no change despite earlier hawkish signals.

Historically, the BOJ has moved cautiously, raising rates only twice recently: to 0.25% in July 2024 and to 0.5% in July 2025, before holding steady at 1% by June 2026[2][6][10]. A Reuters survey in April 2026 cited a former board member predicting two hikes in 2026, yet economist Seisaku Kameda later argued delays were likely amid Middle East conflict volatility[1][4]. By June, 90% of economists still forecasted another hike by December, targeting 1.75% by end-cycle, but July remains a low-probability window[7].

Traders should monitor the BOJ’s Outlook Report released alongside the statement, wage data from the June 2026 Basic Survey, and oil price trends linked to Middle East tensions[1][9]. Deputy Governor Uchida’s recent speech reinforced expectations of a 1% rate, but any surprise inflation spike could alter timing[10]. On Polymarket, the “No change” option dominates at 97%, whereas Kalshi and Betfair typically express such odds in decimal format with differing fee structures and KYC thresholds, creating subtle pricing divergences across platforms[3].
