The Bank of Japan, as widely anticipated, maintained its policy rate unchanged shortly after the U.S. Federal Reserve announced its own decision to hold policy steady. The primary reason cited was significant uncertainty stemming from fresh geopolitical conflicts in the Middle East, which has clouded the economic growth outlook. Concurrently, the central bank pledged in its latest statement that it would swiftly raise borrowing costs if its price growth forecasts are realized.
The yen exchange rate (against the U.S. dollar) showed little immediate movement following the BOJ's decision. However, analysts remain focused on whether the USD/JPY pair might soon breach the critical 160 level and the potential for Japanese government intervention in the foreign exchange market if that key psychological barrier is broken.
Overall, the BOJ held policy steady as expected but did not abandon its future rate hike path. The oil price shock resulting from Middle East geopolitical conflicts is elevating Japan's inflation risks. This inflationary effect from energy costs could become a key factor prompting the BOJ to resume its tightening cycle in April.
According to the statement released after the BOJ's two-day meeting concluded on Thursday, the benchmark interest rate was kept at 0.75%. This outcome aligned with the unanimous forecast from economists. The decision was made by an 8-1 vote, with hawkish board member Hajime Takata dissenting for the second consecutive meeting, advocating for a rate increase.
Following the release, the Nikkei 225 index extended its losses, while the yen showed no significant movement. The conflict involving Iran has placed the BOJ in a delicate position. Sharply rising oil prices are set to push inflation higher, and the subsequent pass-through of elevated energy costs throughout the economy could exert significant pressure on business activity, which is in a recovery phase, and Japan's fragile consumer spending system.
The BOJ avoided sending strong dovish signals, with minor wording changes sparking market speculation about an April hike. The central bank stated it has added the Middle East geopolitical situation to its list of risk factors but did not alter its inflation outlook, suggesting it still sees a potential path for rate hikes in the coming months.
"The BOJ is essentially telling markets it needs more time to assess the situation," said an executive rate strategist. "Given the unpredictable nature of the Middle East conflict, it's unclear how long the global trend of high oil prices will persist. The BOJ likely feels no urgent need to hike rates immediately, but communicating around this issue is extremely challenging."
The BOJ's statement mentioned uncertainties related to the conflict involving Iran and its effects. It noted that risks to the growth outlook include the future developments in the Middle East and the trajectory of crude oil prices. The statement added that the sole dissenting member, Hajime Takata, pointed out that Japan's price risks are skewed to the upside, as overseas developments could trigger second-round effects pushing prices higher.
Simultaneously, the BOJ reiterated its view that price trends will align with its target in the latter half of the current projection period. The Monetary Policy Committee still intends to announce another rate hike if its price outlook is realized. Typically, the BOJ omits wording about its commitment to continue hiking when leaving policy settings unchanged. Its inclusion in Thursday's statement may signal the bank's desire to avoid sending excessively dovish signals that could further weaken the yen.
"The BOJ's policy board will likely judge that there is limited room to act now to demonstrate its commitment to price stability," said a senior economist. "Governor Ueda may hint that an April rate hike is a possibility."
A chief strategist noted that the BOJ's comments regarding the impact of crude oil prices on core CPI suggest that even a new wave of cost-push inflation driven by oil prices could justify a rate hike, "leaving the door open for a potential return to tightening in April."
BOJ Governor Kazuo Ueda is scheduled to hold a press conference at 3:30 PM Tokyo time, where he will elaborate on the decision and his views on the interest rate path. Forex traders will be on alert, as his detailed explanations for holding policy steady have sometimes led to yen depreciation in the past.
Japan is one of the major economies most vulnerable to Middle East tensions, importing over 90% of its oil from the region. According to a government report Wednesday, gasoline prices rose this week to 190.8 yen per liter, the highest level on record since 1990. Prime Minister Tachibana has reinstated gasoline subsidies after winning a national election last month with a core pledge to firmly address the cost-of-living crisis.
The challenge for BOJ officials is that inflation above expectations is becoming entrenched, keeping price increases above the bank's 2% target for a fourth consecutive year. This issue was not present during the previous global supply chain shocks of the pandemic era, as deeply rooted deflationary mindsets among the Japanese public, fostered by prolonged negative rates, resulted in relatively short-lived price spikes.
As the chart indicates, Japanese corporate inflation expectations have risen significantly. The Middle East geopolitical situation is influencing central bank policy expectations globally. As anticipation grows that major central banks may pivot towards tighter policy following the oil price surge towards $110 per barrel, which has boosted inflation and even stagflation fears, policymakers are closely monitoring elevated price levels.
The Reserve Bank of Australia announced another rate hike earlier this week. The U.S. Federal Reserve, early Thursday ET, maintained policy unchanged while projecting the possibility of one rate cut later this year. Pricing in the overnight swap market suggests approximately a 77% probability of the European Central Bank returning to rate hikes in June.
Fed Chair Powell emphasized at a press conference Wednesday that it is still too early to assess the impact of soaring oil prices on the U.S. economy, even though financial markets have quickly priced in higher inflation expectations for the coming year. Instead, he highlighted signs that price pressures were proving more persistent than policymakers had hoped even before the outbreak of the Iran conflict.
Prior to the attacks involving Israel, the U.S., and Iran on February 28, the trends in the Japanese economy and inflation were broadly consistent with the BOJ's outlook. Economic growth in the last quarter of 2025 was higher than the government's initial estimate, and real wages turned positive in January for the first time since 2024, helped by cooling inflation as food prices retreated.
Sources indicated earlier this month that, ahead of Thursday's decision, BOJ officials viewed the duration of the Middle East conflict as a key variable for assessing Japan's economic outlook and interest rate path. Recent robust economic data, coupled with a weak yen, prompted more than a third of BOJ watchers to predict another rate hike in April. Traders generally assign an even higher probability, with overnight swap pricing suggesting about a 60% chance of action next month.
"A key question during Governor Ueda's press conference will be whether the economy and prices remain on track if these external factors are excluded," said a senior chief researcher. "If the impact of the Middle East situation proves temporary, there is reason to expect the narrative for rate hikes could return to the forefront."
The BOJ's decision to stand pat has refocused the forex market's attention on the "yen's 160 line." Finance Minister Tsukiyama said Monday that Japanese monetary authorities are prepared to take decisive action against currency market fluctuations if necessary, as the yen weakens significantly against the dollar amid ongoing Middle East tensions, approaching the critical threshold of 160 yen per dollar.
The fresh Middle East conflict is pushing the yen exchange rate back towards the 160 yen per dollar level, a crucial psychological barrier last seen in July 2024, which was previously considered a potential trigger point for Japanese authorities to intervene in the yen's exchange rate. During the early Asian session, the yen hovered near 159.65 per dollar.
However, with rising oil prices placing substantial pressure on the inflation and growth outlook of Japan, which is heavily reliant on Middle Eastern oil, and global safe-haven demand flooding into the U.S. dollar amid the conflict, significantly boosting the dollar's value, the Finance Ministry's room for intervention in the forex market is likely far more constrained than in the past.
Unlike in 2022 and 2024, when Tokyo swiftly intervened primarily to counter sustained yen selling driven by speculators exploiting the widening interest rate differential between the U.S. and Japan, with relatively positive effects on the exchange rate, the recent breach of the 159 level is more attributable to robust safe-haven demand for the dollar and market concerns that soaring oil prices could damage Japan's fragile economic recovery.
"I think a move to 160 for USD/JPY is possible, but I don't expect it to stay significantly above that level for long," said a foreign exchange and interest rate strategist. "Given Minister Tsukiyama's strong verbal intervention stance, traders are probably unwilling to hold large positions over the three-day holiday period."
"The likelihood of actual intervention seems low, but investors cannot be completely at ease. If authorities resort only to verbal intervention even after USD/JPY breaks 160, the pair will likely continue to rise," said the Asia strategy head at SEB.
"The BOJ's description of war-related risks focused more on their impact on inflation rather than negative effects on growth. In fact, there wasn't much change in the policy guidance wording. For now, USD/JPY is relatively stable. But if Governor Ueda's remarks later lean slightly dovish, the pair will likely find buying support. The market still respects the 160 psychological level. However, the pair's ascent reflects a deterioration in Japan's terms of trade and economy, rather than speculative moves against the yen itself," the strategist added.
"Although the statement included new wording about the Middle East situation and oil prices, these were within expectations, and the basic scenario hasn't changed," said a chief foreign exchange strategist. "There's no need to hastily adjust one's judgment now. Because Finance Minister Tsukiyama has taken a fairly hawkish stance, it has removed the catalyst for immediately testing the upside in USD/JPY. The overall outcome of this meeting is neutral, and the focus now is on whether BOJ Governor Ueda will emphasize a dovish or hawkish tilt in his press conference."
