European stock markets opened with small gains on Monday as investors tracked a renewed spike in oil prices and the escalation of a conflict centred on Iran. Trading participants remained cautious as the situation entered a third week, with energy markets particularly sensitive to disruptions linked to shipping through the Strait of Hormuz.
By 04:04 ET (08:04 GMT), the pan-European Stoxx 600 had risen 0.1%. Germany's Dax also advanced 0.1%, France's CAC 40 climbed 0.1% and the U.K.'s FTSE 100 moved up 0.4%.
The military confrontation, described in reports as a joint U.S.-Israeli assault on Iran, has broadened into a wider regional engagement. Saudi Arabia said it intercepted more than 60 drones flying over its territory, though the Kingdom's defence ministry did not provide details on the drones' origins or intended targets. Against that backdrop, U.S. President Donald Trump urged seven nations to assist Washington in securing passage through the Strait of Hormuz, a narrow waterway that handles roughly a fifth of the world's oil shipments. He did not indicate whether any of those countries had agreed to join the effort.
Iran's actions have effectively halted tanker traffic through the strait, a move that has pushed energy prices sharply higher and clouded the global economic outlook. For Europe in particular, the closure threatens to reaccelerate inflation in a region that, until recently, was thought to have largely reined in price growth. Given Europe's dependence on energy supplies that transit the Hormuz corridor, higher fuel costs may weigh on a continental economy that has shown signs of stagnation.
Rising oil and gas prices have coincided with an uptick in borrowing costs across Europe, reflecting concerns that the European Central Bank may need to revisit its interest rate stance. The Stoxx 600 has come under pressure amid these developments, trading more than 5% below its pre-conflict peak.
The ECB, together with several other major central banks including the Federal Reserve, is set to announce its latest monetary policy decision later this week. Despite the ongoing hostilities in the Middle East, a Reuters poll cited by market observers indicates economists expect the ECB to keep rates unchanged for the remainder of 2026.
Crude market moves
Oil markets traded in a volatile pattern on Monday as investors weighed the prospect of additional supply interruptions from the Middle East. Prices briefly eased after President Trump appealed to other countries - including China - to help restore shipping through the Strait of Hormuz, but by 04:06 ET Brent crude had risen 2.7% to $105.90 per barrel. U.S. West Texas Intermediate crude gained 2.0% to $98.75 a barrel over the same period. Earlier in the session both benchmarks had climbed as much as 3% before moderating.
Implications for markets and policymakers
Investors remain attentive to developments in the Middle East because of the direct link between maritime access in the Hormuz corridor and global energy supplies. For Europe, the combination of higher energy prices and tightening financial conditions increases the risk that domestic inflation will rebound, complicating the ECB's policy deliberations.
At the same time, the immediate market reaction was limited to modest equity gains, underscoring how participants are balancing geopolitical risk with other macroeconomic signals ahead of central bank announcements.
Clear summary
European equities opened slightly higher as oil surged above $100 a barrel amid an expanding conflict involving Iran. Key regional indices posted small gains while Brent and WTI crude rallied, prompting renewed attention on inflation risks and upcoming central bank decisions.
Key points
- Major European indices opened modestly higher - Stoxx 600, Dax and CAC 40 each rose 0.1%, FTSE 100 gained 0.4% (04:04 ET).
- Brent crude rose 2.7% to $105.90 per barrel and U.S. WTI rose 2.0% to $98.75 per barrel (04:06 ET) amid supply concerns tied to the closure of the Strait of Hormuz.
- Higher energy costs and rising borrowing rates are increasing pressure on the European economy and complicating the European Central Bank's policy outlook.
Risks and uncertainties
- Continuation or escalation of hostilities in the Middle East could prolong or worsen disruptions to oil shipping through the Strait of Hormuz, sustaining upward pressure on energy prices - this primarily affects the energy sector and broader inflation dynamics.
- If inflation reaccelerates in Europe, the ECB could face renewed pressure to consider tighter monetary policy, which would impact borrowing costs across sectors reliant on credit.
- Market sentiment is vulnerable to further supply shocks and geopolitical developments, which could weigh on equity valuations already more than 5% below pre-conflict highs - this bears on financials, industrials and consumer-sensitive sectors.
