The Bank of Japan is widely expected to keep its benchmark interest rate on hold at 0.75% when it concludes its two-day April meeting on Tuesday, as the ongoing U.S.-Israeli war with Iran clouds the economic outlook and complicates one of the most delicate tightening cycles in the central bank’s recent history.
Officials have signalled in the days prior to the decision that they see little need to rush a rate increase while the situation in the Middle East remains highly fluid, even as their broader commitment to further tightening stays intact. The decision is expected between 0230 and 0330 GMT, with Governor Kazuo Ueda due to hold a press conference at 0630 GMT. of the Strait of Hormuz has driven crude prices sharply higher. WTI is hovering around $100 per barrel, a level feeding through to corporate cost structures and keeping consumer price inflation above the BOJ’s 2% target for a fourth consecutive year.
That persistent inflation has put the BOJ in an awkward position. While the war-driven oil shock would ordinarily justify a pause in rate hikes, the risk of allowing firms to entrench higher prices into wages and output costs has grown. A stubbornly weak yen, currently near the 160-per-dollar level that has previously triggered currency intervention, is adding to imported inflation and piling pressure on Ueda to signal a firmer tightening bias at his press conference.
Hawkish board member Hajime Takata is expected to again propose raising the policy rate to 1.0%, a move that would align with projections markets held earlier in the year. The proposal is likely to be voted down, as it was at the two preceding meetings, reflecting the board’s preference for caution given the external environment.
The quarterly outlook report due alongside the rate decision is expected to show the BOJ cutting its fiscal 2026 growth forecast as surging fuel costs weigh on corporate profits and consumer spending. At the same time, the inflation outlook is set to be revised sharply higher, reflecting rising oil-related input costs and growing evidence that firms are passing those costs on to customers.
UBS economists revised away from an April hike call earlier this month, citing a significant fading in market expectations, though the broader consensus has not abandoned the tightening narrative. Nearly two-thirds of economists in a Reuters poll still expect the benchmark rate to reach 1.0% by the end of June.
With the rate decision itself largely a foregone conclusion, the market focus falls squarely on Ueda’s tone. A clear signal that the BOJ stands ready to resume hiking once the fog of the Iran conflict lifts could offer the yen meaningful support and reassure investors that Tokyo has not quietly shelved its path toward policy normalisation.

Bearish for the yen near term, with an expected BOJ hold reinforcing the wide rate differential with the U.S. Fed and keeping the currency close to the 160-per-dollar intervention threshold. Bullish for Japanese import-cost inflation, as the Hormuz disruption sustains elevated crude prices and adds to pipeline price pressure. Hawkish guidance from Ueda at his post-decision press conference could offer the yen modest support.
The quarterly outlook report is a key watch: a simultaneous downward revision to growth and upward revision to inflation would deepen the BOJ’s dilemma and could unsettle JGB markets. UBS has already revised away from an April hike call, citing significantly faded market expectations
