BOJ holds 1%; core inflation warning keeps yen intervention zone in focus

The Bank of Japan kept its policy rate at 1% on July 31, with an 8-1 vote and one board member, Hajime Takata, proposing a hike to 1.25%. The decision qualifies as a Tier-1 central-bank event because the rate hold came with a fresh inflation warning and a live foreign-exchange backdrop.

The BOJ said core inflation could run clearly above its 2% target from the second half of fiscal 2026, which begins in September and runs through March. CNBC reported that the central bank cited wage increases passing into selling prices, higher crude oil prices, and recent yen depreciation. July core inflation was 1.6%, below 2%, so the statement shifted attention from the current reading to the forward path.

The currency channel is the market risk. The yen had traded around 163 per dollar before strengthening to as high as 157.96 after Japan reportedly intervened and U.S. authorities conducted a rate check. That sequence put the 162-165 zone back into focus for FX desks because yen weakness feeds import prices, household inflation, and hedging costs for global investors.

For Japanese equities and rates, the signal is mixed. A hold at 1% avoids an immediate shock to duration-sensitive shares and banks' funding costs, but an explicit warning about inflation above 2% keeps the September-to-March window active for another policy move. The next data points are national CPI, wage-settlement follow-through, crude prices, and any official disclosure around currency intervention operations.
