BOJ's Steady Hike Path May Be Underpricing Middle East Supply Shock Risk

The market's expectation for the Bank of Japan is largely unchanged by the recent Middle East conflict. A Reuters poll found that 60% of economists expect the BOJ to raise its key rate to 1.00% by end-June, a figure that is largely unchanged from February's poll. This stability suggests the war's inflationary shock is being weighed against the bank's existing, deliberate hawkish trajectory rather than creating a new, disruptive catalyst. The consensus view is that the BOJ will continue its gradual normalization, with Nomura assigning a 60% probability to three more rate hikes by mid-2027, lifting the policy rate to 1.50%.

Viewed another way, the Middle East war may simply be reinforcing a trend the market already priced in. The conflict has stoked global inflation fears and driven oil prices higher, which could pressure Japan's import costs and weaken the yen further. Yet, the BOJ's policy path has been guided by a similar calculus for months: a cautious but steady climb to exit negative rates. The bank's recent decision to keep rates at 0.75% next week aligns with this measured pace, and the unchanged poll expectations indicate that the war's impact is being absorbed into that existing framework.

The broader context for central banks also points to a delayed easing cycle. As Nomura's head of wholesale division noted, central banks are going to remain vigilant for longer, with rate cuts coming "a little bit later." This sentiment, echoed across major developed markets, creates a backdrop where the BOJ's gradual hike is not an outlier but part of a global pattern of delayed monetary policy easing. The risk here is not a sudden shift, but a prolonged period of elevated rates, which Nomura's analysis suggests could see Japan's policy rate settle higher than previously assumed if inflation persists.

The bottom line is one of expectations gap. The market is not pricing in a BOJ pivot due to the Middle East war; it is pricing in a continuation of a slow, steady hike. The conflict adds a layer of uncertainty to the inflation outlook, but it has not altered the fundamental setup that was already in motion. For now, the catalyst is not new-it is simply the latest data point in a trend the consensus has already accepted.

The Asymmetry of Risk: Inflation vs. Growth

The Middle East war introduces a classic central banking dilemma: a two-sided risk that complicates the BOJ's path. On one side, higher oil prices and a weaker yen directly increase inflationary pressures. On the other, those same higher fuel costs hit Japan's economic growth, which is heavily reliant on imported energy. The bank's response is complicated by this asymmetry.

The inflationary push is clear. The war has driven oil prices higher, adding to rising import costs from a weak yen that have kept core inflation above the BOJ's 2% target for nearly four years. Governor Kazuo Ueda has acknowledged this duality, noting that rising oil prices could push up underlying inflation by heightening long-term inflation expectations. This is the pressure the BOJ is mandated to counter.

Yet the growth hit is equally real. Japan's heavy reliance on Middle East oil may magnify the hit to corporate profits and the economy from rising fuel costs. For a central bank that also monitors economic activity, this creates a direct conflict. Raising rates to fight inflation could further dampen an already-stressed economy, while delaying a hike risks letting inflation expectations become entrenched.

This tension is why the BOJ is taking a data-dependent approach. Governor Ueda has stated the bank will scrutinise data at its March and April meetings, leaving the timing of a near-term hike open. The goal, as analysts interpret it, is to keep the next meeting in April live for a hike without in any way locking it in. This cautious stance reflects the bank's effort to balance its dual mandate in a volatile environment.

The bottom line is one of uncertainty, not a clear signal. The BOJ is not ignoring the growth risk; it is explicitly weighing it. By deferring a firm commitment until after its April meeting, the bank is prioritizing data over dogma. This leaves the market in a holding pattern, with the consensus view of a 60% chance for a hike in April hanging on the next batch of economic indicators. For now, the asymmetry of risk means the BOJ is choosing to wait, not because it is indecisive, but because the data has not yet resolved the conflict between inflation and growth.

Valuation and Sentiment: What's Already Priced In?

The market's sentiment on the BOJ remains remarkably stable, which itself is a signal. The Reuters poll showing 60% of economists expect a hike to 1.00% by end-June, unchanged from February, indicates the consensus view has not materially shifted despite the new Middle East uncertainties. This stability suggests the market is underestimating the volatility risk. The conflict introduces sharp swings in oil prices and the yen, yet the forward pricing of policy has not adjusted for this heightened turbulence. The risk is that a sudden, severe supply shock could force the bank's hand faster than the current consensus anticipates.

This setup carries a clear warning from the bank's own recent actions. The BOJ's decision to raise rates last week triggered significant market turmoil, drawing criticism for its role in unwinding massive carry trades. As a senior Nomura executive noted, the BOJ has faced criticism for its role in triggering market turmoil. The bank's timing was later vindicated, but the episode underscores the peril of policy missteps in a fragile market. The current calm may be a false sense of security, masking the potential for another sharp reaction if the BOJ moves again too abruptly.

Fresh supply shocks from the Middle East conflict may indeed speed up the BOJ's agenda. Four sources familiar with its thinking say these shocks may speed up the Bank of Japan's hawkish agenda by increasing inflationary risks. This creates a tangible path for a rate hike as soon as April, a timing that 27% of economists in the Reuters poll already see as possible. The bottom line is one of asymmetry: the market is pricing in a steady, predictable climb, but the new conflict introduces the risk of a faster, more disruptive pace. For now, the consensus view is priced for perfection, leaving little room for error.

Catalysts and Key Watchpoints

The market's current 60% expectation for a BOJ hike in April is a fragile consensus, resting on a few concrete data points and events. The bank's decision this Thursday will be the first major test. While a rate hike is not expected, the focus will be on Governor Kazuo Ueda's tone at the post-meeting briefing. Analysts expect him to keep the next meeting in April live for a hike without in any way locking it in. Any shift in language that suggests a firmer commitment-or a more explicit delay-would immediately challenge the market's forward view.

The domestic inflation engine is another key watchpoint. The outcome of Japan's spring wage negotiations will be a critical signal for the persistence of price pressures. Governor Ueda has noted that the BOJ's target could be achieved earlier than projected if the outcome of this year's spring wage negotiations... proves stronger than expected. Stronger-than-anticipated wage gains would support the bank's case for continued hikes, while a weak settlement could fuel arguments for patience, especially if growth concerns intensify.

Then there is the external shock itself: the duration and escalation of the Middle East conflict. This is the most volatile catalyst. The war has already driven oil prices higher, adding to rising import costs from a weak yen that have kept core inflation elevated. The BOJ's own analysis acknowledges that the aim... will be to keep the next meeting in April live for a hike without in any way locking it in, with the timing depending much on how long the war could last. A prolonged or escalated conflict would likely force a faster policy response, while a swift de-escalation could allow the bank to maintain its cautious, data-dependent pace.

The bottom line is that the consensus view is priced for a steady climb, but the path is littered with these specific, high-impact catalysts. The Thursday decision sets the tone, the wage talks feed the inflation narrative, and the Middle East war dictates the external pressure. Any deviation from the expected script on any of these fronts could quickly unravel the current 60% probability, revealing the true volatility the market has so far underpriced.
