Japan Warns Oil Price Surge from Middle East War Could Drive Inflation Higher

TOKYO, March 19, 2026 — Japan has warned that a surge in global oil prices driven by the escalating conflict in the Middle East could lead to higher inflation, adding pressure on its already fragile economic outlook.

The warning came from the Bank of Japan (BOJ), which said that recent increases in crude oil prices are expected to push consumer prices upward in the coming months. The central bank noted that while inflation had shown signs of easing due to lower food costs, the latest energy price spike could reverse that trend.

The surge in oil prices is closely linked to ongoing geopolitical tensions in the Middle East, which have disrupted global energy supply chains. Analysts say that the conflict — particularly around key oil transit routes — has triggered significant volatility in global energy markets.

The Strait of Hormuz, a critical shipping route responsible for around 20% of the world’s oil supply, has been severely affected by the crisis, contributing to sharp increases in crude prices.

For Japan, the impact is particularly severe. As one of the world’s largest energy importers, the country relies on the Middle East for about 95% of its oil supply, making it highly vulnerable to price fluctuations.

Despite rising inflation risks, the Bank of Japan decided to keep its key interest rate unchanged at 0.75%, signalling a cautious approach to monetary policy amid economic uncertainty.

Policymakers noted that while inflation could temporarily exceed targets due to higher energy costs, long-term price stability still depends on broader economic factors such as wages and domestic demand.

At the same time, some policymakers have warned that prolonged energy price increases could force the central bank to reconsider its policy stance, including potential rate adjustments.

In response to rising fuel costs, the Japanese government has introduced emergency subsidy programmes aimed at reducing the burden on consumers, particularly in gasoline prices.

These measures are designed to cushion the impact of global energy price shocks on households and businesses, as public concern over rising living costs continues to grow.

Japan’s warning reflects a broader global trend, as countries around the world grapple with the economic consequences of rising oil prices.

The ongoing conflict has already pushed oil prices above US$100 per barrel, with analysts warning that prolonged disruption could lead to sustained inflation and slower economic growth globally.

Economists caution that energy-dependent economies, particularly in Asia, are among the most exposed to these risks, facing higher import costs and potential currency pressure.

As geopolitical tensions continue to drive volatility in global energy markets, Japan’s outlook highlights the fragile balance between economic recovery and rising inflation. The situation remains highly uncertain, with future developments in the Middle East likely to play a critical role in shaping global economic conditions.
