BOJ's Ueda Warns 5th Oil Shock Could Test Japan's Inflation Regime
4 articles · Updated · Bloomberg · May 27
Kazuo Ueda said Japan is facing a “fifth oil price shock,” warning that rising oil prices could affect the underlying inflation trend rather than just headline energy costs.
Speaking at a two-day international banking conference in Tokyo on Wednesday, the BOJ governor said Japan’s history shows oil shocks become broader tests of the entire inflation regime.
Ueda stopped short of signaling how that risk might shape next month’s BOJ policy decision, leaving markets without a clear hint on the rate outlook.
The remarks frame oil as a wider monetary-policy concern for Japan, where the durability and composition of inflation remain central to the BOJ’s next moves.
With oil prices soaring, is the Bank of Japan being forced to choose between inflation and recession?
Has Japan’s 50-year failure to achieve energy security made a new economic crisis inevitable?
Fifth Oil Shock Hits Japan: BOJ Warns of Persistent Inflation as Yen Slides and Energy Prices Surge
Overview
Japan is facing its fifth major oil shock in May 2026, triggered by escalating tensions in the Middle East and the Iran war, which have driven up global energy prices. The Bank of Japan, led by Governor Kazuo Ueda, has warned that this temporary energy shock could turn into persistent inflation, especially as a significantly weaker yen amplifies the impact of rising import costs. The yen’s depreciation has made imported energy and goods more expensive, fueling inflation and testing Japan’s economic resilience. Policymakers are now challenged to prevent this shock from embedding long-term inflation into the economy.
