BOJ Poised to Lift Inflation Projection as Oil Surge Bites

Bank of Japan officials are likely to raise their inflation projection for the current fiscal year to account for a roughly 50% jump in oil prices since the start of the US-Iran war, and may lower growth forecasts as the Middle East conflict continues to cloud the outlook. The yen strengthened slightly after the report, and the BOJ will release an updated outlook and decide on policy rate settings at the end of a two-day meeting on April 28.

Key Points

  • BOJ likely to raise its inflation forecast for the current fiscal year from 1.9% to account for a roughly 50% rise in oil prices since the US-Iran war began.
  • Officials are expected to consider trimming the economic growth forecast amid ongoing uncertainty over the Middle East conflict and the adverse effect of oil spikes on terms of trade.
  • The BOJ will update its quarterly outlook and decide on the policy rate at the end of its two-day meeting on April 28; the currency market showed a modest yen strengthening after the report.

Overview

Bank of Japan officials are widely expected to consider increasing their inflation forecast at the policy meeting scheduled for late April, principally to reflect the impact of elevated oil prices, people familiar with the matter told Bloomberg.

Inflation projection under review

The BOJ's policy board is likely to discuss raising its central price projection for the current fiscal year from the present 1.9%. That consideration comes after oil prices rose by roughly 50% since the onset of the US-Iran war, according to the sources. The projected inflation figure under review is the BOJ's key metric for price developments over the fiscal year.

Growth forecast may be scaled back

With the outlook for the Middle East conflict remaining uncertain, officials are also expected to weigh lowering their economic growth forecast. The rationale cited by the sources is that spikes in oil prices have historically dampened Japan's economic performance by worsening the nation's terms of trade, given Japan's dependence on imported natural resources.

Market reaction and timing

The yen firmed to 158.81 against the dollar on the report, moving from 159.07 immediately beforehand. The BOJ will publish its quarterly economic outlook statement and announce its policy rate decision at the close of a two-day meeting on April 28, when it will also consider whether to raise its policy rate from 0.75%.

Rate expectations and central bank signalling

Expectations of a rate increase at the meeting have softened as the Middle East crisis persists. Comments from Governor Kazuo Ueda earlier in the week highlighted the lack of clarity about how the conflict might evolve, and did not offer a clear signal pointing toward a rate hike. The sources noted that on the last two occasions the BOJ raised borrowing costs, the governor had telegraphed those moves in advance.

Implications

Officials appear to be balancing the need to reflect recent oil-driven inflation pressures in official projections against the risk that higher energy costs will weigh on growth. The immediate market response in the currency market was modest, with a small strengthening of the yen against the dollar after the report became public.

Risks

  • Persistent Middle East conflict - Continued geopolitical uncertainty could keep oil prices elevated and further pressure Japan's growth outlook, affecting sectors sensitive to energy costs such as transportation and manufacturing.
  • Weaker signals on rate direction - The lack of clear guidance from the BOJ governor may dampen expectations for an imminent rate hike, creating uncertainty for financial markets and yield-sensitive sectors.
  • Terms of trade deterioration - Higher import costs for energy and other natural resources could weigh on corporate margins and broader economic activity, impacting trade-exposed industries.
