European stock markets opened lower after a fresh escalation of hostilities in the Gulf raised concerns that a fragile pause in direct U.S.-Iran confrontation - and any nascent peace arrangements - may be at risk.
By 03:02 ET (07:02 GMT), the pan-European Stoxx 600 had fallen 0.4%. In national markets, Germany's Dax was down 0.5%, France's CAC 40 slipped 0.4% and the U.K.'s FTSE 100 opened 0.7% lower.
The market moves followed reports that the U.S. military carried out additional strikes in Iran on Wednesday, in response to earlier Iranian drone attacks on commercial vessels in the Strait of Hormuz. The Wall Street Journal reported the U.S. actions, citing two officials familiar with the matter.
Diplomatic efforts to secure a longer-term resolution to the roughly three-month old conflict were continuing, the reports said, but had not produced an immediate settlement.
Separately, Kuwait's military announced it had intercepted missile and drone attacks, ending a period of several weeks without strikes in the region. The U.S. was reported to have shot down a drone and struck a drone-control station near the southern Iranian port city of Bandar Abbas, the Wall Street Journal said. Iran's Islamic Revolutionary Guard Corps stated it had struck an American base and warned it would retaliate against any future attacks.
Energy markets reacted to the heightened tensions. Brent crude futures rose 2.6% to $96.72 a barrel - a meaningful uptick that nevertheless kept prices below the $100-per-barrel level and above levels seen before the onset of the conflict.
The early declines in European equities and the rise in oil prices illustrate the immediate market sensitivity to developments in the Gulf. Trading opened with risk-off positioning in major equity benchmarks while commodity markets priced in a higher premium for supply uncertainty.
Market context and implications
The initial trading reaction reflected a combination of geopolitical risk and commodity price response. While the equity moves were modest in percentage terms, the alignment of downward pressure across the Stoxx 600, Dax, CAC 40 and FTSE 100 underscores broad investor caution amid the renewed hostilities and related military activity.
Energy prices, as captured by Brent futures, saw a notable rise as participants recalibrated supply risk assessments. The price remained under $100 per barrel but materially higher than pre-conflict levels, signalling continued sensitivity to escalation.
What remains uncertain
Diplomatic channels were reported to be active but had not delivered a resolution at the time of the market open. The duration and trajectory of any further military exchanges - including potential retaliatory actions by Iranian forces or allied groups - remain unclear based on the available reporting.
Investors entering the session faced ongoing uncertainty about whether the recent strikes would deepen the conflict or be contained, and how energy markets and equity risk appetite would respond in subsequent trading.
