European Shares Fall, Oil and Gold Rise After U.S.-Israel Action in Iran
European financial markets reopened to turbulence after weekend military strikes by the United States and Israel on Iran and the killing of Supreme Leader Ali Khamenei. The reaction was immediate: equities retreated, energy prices advanced, and investors pivoted toward traditional havens.
European equities decline as Iran conflict boosts oil and defense stocks, hits travel shares, and intensifies inflation and growth concerns.

The rebound in oil and gas prices underscored the emergence of what traders now describe as the “war trade,” adding to an already active AI “scare trade.” Gold strengthened, and the dollar attracted demand despite uncertainty linked to Donald Trump. Geopolitical tensions are reshaping market risk assessments in real time.
A sharp downturn swept across key indexes. The STOXX Europe 600 declined 1.6%, matching losses seen in Germany’s DAX. Britain’s FTSE 100 fell 0.75%. Financial institutions were among the hardest hit, with Barclays sliding 5%. Airline group International Airlines Group dropped more than 6%.
Travel and hospitality stocks bore the brunt of investor anxiety. The prospect of prolonged instability across the Middle East has raised fears of disrupted flight paths and suspended routes through a critical aviation corridor. Dubai International Airport, which processed 95.2 million passengers in 2025, stands at the heart of global connectivity between America, Europe, India, and Asia-Pacific economies.
Authorities in the United Arab Emirates suspended financial market operations for two days as a precaution. Meanwhile, shipping insurers grew increasingly cautious about vessels transiting the Gulf.
Energy security remains central to market calculations. Roughly one-fifth of global oil shipments pass through the Strait of Hormuz, and any prolonged military campaign—potentially lasting up to four weeks, according to the U.S. president—could intensify pressure on this chokepoint. The alternative export route via the Red Sea and Bab el-Mandeb is already exposed to risks stemming from Houthi attacks linked to Yemen’s conflict.
European gas futures have surged 25%, raising concerns that a Ukraine-style energy shock could reemerge. Analysts caution that if crude prices reach $100 per barrel, inflation could accelerate over the summer, weighing on worldwide economic expansion.
According to a weekend research note from Goldman Sachs, the principal channel through which the Iran crisis would influence global macroeconomic conditions is the energy market. The degree of disruption and its duration are decisive variables. The bank expects risk premiums to widen initially, though it noted that some growth and inflation pressures were already embedded in market pricing before the latest escalation.
Despite the turbulence, broad-based panic has yet to take hold. Early sectoral moves show divergence: defense companies such as Thales and BAE Systems advanced, alongside oil major Shell. Conflict continues to create relative winners even as broader indices retreat.
Investor unease predates this geopolitical shock. Significant uncertainty surrounds the deployment of vast capital commitments intended to build out agentic AI infrastructure. Heightened instability may reinforce cautious positioning and dampen confidence further.
Yet markets are not in free fall. Sustained upward pressure on oil prices would be necessary to inflict lasting economic damage. For now, impacts appear concentrated in energy, defense, aviation, and transport. As valuations decline on initial headlines, opportunistic buyers may reenter positions.
Reflecting on uncertainty decades ago, former British prime minister Harold Macmillan famously pointed to “events” as the greatest challenge to forecasting. Today’s market response suggests that investors have internalized that lesson. Geopolitical volatility is no longer an anomaly—it is embedded in the system.
