Key Takeaways

• Rates on hold, but barely: The BOJ kept its overnight call rate at 0.75%, though the decision was split — three of nine board members pushed for an immediate hike.
• Hawkish outlook: The central bank pledged to “continue to raise the policy interest rate” amid mounting inflationary pressures.
• June hike expected: Capital Economics and several major brokerages now project a 25 basis point increase at the next meeting.
• Inflation forecasts soar: Headline CPI for fiscal 2026 was lifted to 2.8%–3.0% (from 1.9%–2.0%), while core CPI was raised to 2.5%–2.7% (from 2.0%–2.3%) — well above the BOJ’s 2% target.
• Growth outlook cut: Real GDP for fiscal 2026 is now seen at just 0.4%–0.7%, down from 0.8%–1.0%, with forecasts for 2027 and 2028 also trimmed.
• Oil shock the culprit: The BOJ blamed elevated crude prices from the Middle East war for both the inflation spike and the growth downgrade.
• Tightening cycle continues: The central bank has raised rates by a cumulative 85 basis points since early 2024, when it ended nearly a decade of ultra-loose policy.

The Bank of Japan kept interest rates on hold as widely expected on Tuesday, but issued a clear warning over slowing economic growth and intensifying inflation pressures stemming from the war in the Middle East.

The BOJ maintained its overnight call rate at 0.75%. However, the decision was not unanimous — three members of the nine-strong rate-setting board pushed for higher interest rates, citing escalating inflationary risks.

The central bank stated it will “continue to raise the policy interest rate and adjust the degree of monetary accommodation,” particularly in the face of mounting inflationary threats to the Japanese economy.

A Hawkish Hold

“While the Bank of Japan left interest rates unchanged today, its Outlook report was hawkish and we’re sticking to our forecast that the Bank will hike rates in June,” analysts at Capital Economics said in a statement. Capital Economics and several other brokerages are calling for a 25 basis point hike in June.

The BOJ said in its statement that consumer price index inflation is now expected to come in significantly higher than originally forecast for fiscal 2026. Headline CPI inflation is now projected within a range of 2.8% to 3.0% in 2026 — far above the previous forecast band of 1.9% to 2.0%.

Core CPI, which strips out fresh food and energy prices, is now projected between 2.5% and 2.7% in 2026, up from earlier forecasts of 2.0% to 2.3%. The reading is now expected to drift even further above the BOJ’s 2% annual target.

Growth Faces Headwinds

Japan’s economic expansion is likely to lose momentum in fiscal 2026, the BOJ cautioned, pointing to the toll of elevated crude oil prices triggered by the Middle East war.

Real gross domestic product in fiscal 2026 is now anticipated between 0.4% and 0.7%, down from previous projections of 0.8% to 1.0%. The BOJ also trimmed its forecasts for fiscal 2027 and 2028.

Capital Economics analysts observed that the BOJ’s GDP outlook was “a touch more downbeat than we had anticipated,” noting that the central bank appeared particularly worried about inflation drifting further to the upside.

The BOJ warned that surging oil and energy prices are likely to be passed through to consumers and erode corporate profits, while also weighing on overall economic growth.

Even so, resilient private spending and steady corporate earnings are still expected to provide important support to the economy in the years ahead, the BOJ noted.

A Steady Path of Tightening

The central bank has raised interest rates by a cumulative 85 basis points since early 2024, when it brought an end to nearly a decade of ultra-loose monetary policy. Markets broadly expect the BOJ to deliver further rate increases in the coming months, especially given the heightened inflation risks emanating from the Middle East conflict.
