Traders assign roughly even implied probabilities across the 140-170 range for USD/JPY at year-end 2026, underscoring uncertainty over interest-rate differentials between the Federal Reserve and Bank of Japan. Recent U.S. inflation releases and labor-market data have tempered expectations for aggressive Fed easing, while the BoJ’s gradual policy normalization and any potential yen interventions remain key swing factors. Yield spreads on 10-year Treasuries versus Japanese government bonds, combined with broader risk sentiment and dollar demand, continue to anchor positioning. Upcoming FOMC and BoJ meetings, plus September CPI and employment figures, will likely refine these probabilities as markets price in the final 2026 trajectory.
