Euro bulls retreat as US dollar rallies on Iran tensions and inflation worries

The euro is struggling to hold its ground against the US dollar as of mid-May 2025, with the EUR/USD pair retreating from recent highs. The greenback has found fresh support from escalating geopolitical tensions between the United States and Iran, coupled with renewed inflation fears that are prompting traders to reassess the Federal Reserve’s policy path.

Geopolitical risk bolsters safe-haven dollar demand

The US dollar has strengthened as a safe-haven asset following a series of diplomatic escalations between Washington and Tehran. Reports of increased US naval deployments in the Persian Gulf and renewed sanctions rhetoric have stoked uncertainty in global markets. Historically, the dollar tends to gain during geopolitical crises, and this pattern has reasserted itself in recent sessions, pushing the euro lower.

Market participants are watching for any further developments that could disrupt oil supply routes or trigger broader regional instability. The euro, already under pressure from a sluggish European economic outlook, has found little support from the European Central Bank’s recent policy signals.

Inflation data reinforces hawkish Fed expectations

On the macroeconomic front, the latest US consumer price index (CPI) data, released in early May, came in above consensus estimates. The core CPI rose 3.4% year-over-year, exceeding the 3.2% forecast, which has dampened hopes for an imminent rate cut by the Federal Reserve. Higher-than-expected inflation keeps the Fed in a tightening bias, making the dollar more attractive to yield-seeking investors.

This divergence in monetary policy expectations is a key driver behind the euro’s weakness. While the Fed remains cautious about easing, the ECB has already signaled a potential rate cut as early as June, given the eurozone’s softer economic data. This policy gap favors the dollar.

Technical picture: Euro bulls lose momentum

From a technical analysis perspective, the EUR/USD pair has broken below its 50-day moving average, a bearish signal that suggests further downside risk. The pair is currently trading near the 1.0800 level, with the next support zone around 1.0720. Resistance now sits at 1.0900, which was tested and rejected earlier this week.

Traders are reporting reduced long positions on the euro, with speculative net longs declining for the second consecutive week, according to the latest CFTC data. This shift in sentiment aligns with the broader risk-off mood driven by geopolitical headlines.

Conclusion

The euro’s near-term outlook remains challenged by a combination of geopolitical risk and persistent US inflation. Without a de-escalation in US-Iran tensions or a surprise dovish pivot from the Fed, the dollar is likely to maintain its advantage. Traders should monitor upcoming US jobs data and any diplomatic breakthroughs in the Middle East as potential catalysts for a reversal.

FAQs

Q1: Why is the US dollar gaining against the euro?
The US dollar is strengthening due to safe-haven demand from US-Iran tensions and higher-than-expected US inflation data, which reduces the likelihood of a Fed rate cut soon.

Q2: What is the key support level for EUR/USD?
The immediate support is around 1.0800, with a stronger support zone near 1.0720. A break below that could open the door to further losses toward 1.0600.

Q3: How might the ECB’s policy affect the euro?
If the ECB cuts rates in June as widely expected, the interest rate differential between the US and eurozone would widen further, putting additional downward pressure on the euro against the dollar.
