Published: May 03, 2026

Key Points

• The U.S.-Iran war and rising oil prices may delay interest rate cuts, keeping inflation persistent across major central banks.
• The Bank of Japan faces increasing pressure to tighten monetary policy due to the weakening yen, which raises import costs.
• Volatility in USDJPY, EURJPY, and GBPJPY is influenced by rate differentials, intervention risks, and key technical levels.

Central Banks and Inflation

The Japanese yen has regained attention as central banks navigate a challenging environment. The Federal Reserve (Fed), European Central Bank (ECB), and Bank of England (BOE) are shifting away from easy monetary policies as inflation risks resurface. The ongoing U.S.-Iran conflict has altered market sentiment, leading to higher oil prices that could increase transportation and food costs, thereby slowing the pace of potential rate cuts.

Federal Reserve's Stance

The Fed has opted to maintain interest rates, revealing divisions among its officials regarding future easing. Market expectations have shifted, indicating no rate cuts in 2026, with potential hikes anticipated in early 2027. This cautious approach is driven by rising inflation, with the Consumer Price Index (CPI) reaching 3.3% and core CPI at 2.6% in March.

ECB and BOE Responses

Both the ECB and BOE have also held rates steady, but the ECB hinted at possible hikes in June if energy prices continue to rise. This reflects a broader concern among central banks regarding the impact of oil prices on inflation. The BOJ, having previously abandoned its negative rate policy, is now under pressure to respond to the yen's weakness, which has exacerbated import costs.

Bank of Japan's Dilemma

The BOJ maintained a rate of 0.75%, but dissenting voices within the bank are advocating for an increase. The yen's depreciation has led to higher prices for oil, food, and raw materials, pushing inflation rates up to 1.5% in March. The BOJ faces a critical decision between prioritizing growth or price stability, especially as government bond yields reach historic highs.

Market Implications for Currency Pairs

USDJPY

The USDJPY pair remains influenced by the disparity in interest rates between the U.S. and Japan. Recent interventions by the BOJ have temporarily stabilized the yen, but further interventions may be necessary if USDJPY approaches 160 again. The pair's immediate support is at 154, with a bullish trend intact as long as it remains above 150.

EURJPY

EURJPY is experiencing a more balanced dynamic, with both the ECB and BOJ cautious about inflation. The pair is trading within a rising trend, with key resistance at 188 and support at 182. A break below 182 could lead to further declines, while a move above 188 would signal a strong bullish momentum.

GBPJPY

GBPJPY is affected by the BOE's steady rate policy, which has left the pound vulnerable. The pair has found support at 210, with a critical level at 212. A close below 210 could indicate further downside, while a recovery above 215 would maintain bullish momentum.

Conclusion

The future of yen pairs hinges on the balance between inflation pressures, central bank policies, and Japan's response to currency weakness. The ongoing U.S.-Iran conflict and high oil prices are likely to keep interest rates elevated globally, putting additional strain on the yen. The BOJ's next actions will be crucial for the direction of USDJPY, EURJPY, and GBPJPY.
