BOJ deputy warns on inflation as Polymarket puts 2026 Fed hike odds at 66%

BOJ Deputy Governor Himino’s Hawkish Inflation Warning Pushes Polymarket “Fed Rate Hike in 2026?” Odds to 65.5%

Bank of Japan Deputy Governor Ryozo Himino warned inflation could overshoot the 2% target and argued the cost of moving too late on rates may be high, reinforcing expectations for further tightening. On Polymarket, traders nudged up the odds in the Federal Reserve contract “Fed rate hike in 2026?” to 65.5% from 66.5%.

Key Takeaways

• Polymarket prices a 65.5% chance that the Federal Reserve will hike rates in 2026 (Yes 65.5%, No 34.5%).
• Traders marked up the Fed-hike contract after hawkish BOJ commentary highlighted ongoing inflation risks and the cost of delayed tightening.
• The contract is set to resolve on Dec. 9, 2026, and the implied odds are up 31 percentage points over both the past 24 hours and 7 days.

Bank of Japan Deputy Governor Ryozo Himino said inflation could rise above the central bank’s 2% target and stressed that acting too late on interest rates carries economic risks, signaling a willingness to keep lifting borrowing costs. His comments followed a BOJ rate increase to 1%, described as a 31-year high, and reinforced expectations for another hike later this year. Minutes from the BOJ’s April meeting showed some board members saw room to accelerate the pace of hikes, including one view favoring an increase once every few months. Himino said supply shocks could broaden price gains and influence underlying inflation, while he also pointed to demand-side strength such as robust corporate profits, steady wage gains and global AI-related demand. He told lawmakers the BOJ was closely monitoring currency moves, and the bank is due to meet again in July when it will publish updated quarterly growth and inflation forecasts.
