EUR/USD rose on Tuesday as the US Dollar eased ahead of a deadline set by US President Donald Trump for Iran to reach a deal or open the Strait of Hormuz. EUR/USD traded near 1.1571, while the US Dollar Index was around 99.90 after failing to hold above 100.
Trump said the US would destroy Iran’s energy and civilian infrastructure if no agreement is reached by 8:00 p.m. Eastern Time (00:00 GMT Wednesday). Iran’s Tehran Times reported that Tehran has suspended all diplomatic and indirect communication channels with the US.
Energy Shock And Currency Impact
Oil prices were already high, and further escalation could lift energy costs and inflation while weighing on growth. The Eurozone, a net energy importer, is more exposed than the US, which is a net energy exporter.
Eurozone inflation data showed the HICP rose 1.2% month-on-month in March, up from 0.6% in February, and annual inflation rose to 2.5% from 1.9%. US CPI later this week is expected at 0.9% month-on-month versus 0.3%, with annual inflation forecast at 3.3% versus 2.4%.
Markets expect the Federal Reserve to hold rates, while pricing up to two ECB rate rises by year-end. New York Fed President John Williams said policy is “well-positioned to wait and see”, and warned the war could add “a tenth or two” to core inflation.
We are seeing a familiar pattern emerge today, reminiscent of the tensions in 2025 surrounding the US-Iran ultimatum. Renewed instability in the Strait of Hormuz is once again pushing energy prices higher and shaping central bank expectations. This playbook suggests the US Dollar is better positioned to handle the shock than the Euro.
Trading And Positioning Implications
Brent crude futures have surged past $95 a barrel this month, a level not seen since the crisis in late 2025. This directly impacts inflation, with the latest US Consumer Price Index for March 2026 coming in at a stubborn 3.4% year-over-year. Meanwhile, Eurostat’s flash estimate for March showed inflation at 2.6%, creating a headache for policymakers in Frankfurt.
The key takeaway is the diverging impact on monetary policy, just as we analyzed last year. As a major energy producer, the United States economy can better absorb higher oil prices, allowing the Federal Reserve to focus purely on taming inflation. The Eurozone, a net energy importer, faces the difficult prospect of both slowing growth and rising prices.
For derivative traders, this dynamic points toward a weaker EUR/USD in the coming weeks. We should consider buying EUR/USD put options to capitalize on a potential decline toward the 1.0500 support level. The rising geopolitical risk also increases implied volatility, making strategies like selling out-of-the-money call spreads attractive.
This policy divergence also presents clear opportunities in interest rate markets. The Fed is now widely expected to delay any potential rate cuts, while the European Central Bank may be forced to pause its tightening cycle sooner than anticipated. This suggests we should position for a widening of the interest rate differential between US and European government debt.
Given that oil is the source of the volatility, positioning directly in energy derivatives is crucial. Buying call options on WTI or Brent crude futures provides a direct hedge and a way to profit from any further escalation. We must remain nimble as the situation can change rapidly, just as it did in 2025.
