European equity markets declined on Thursday morning, pulled lower by sharp losses in the technology sector. Investors weighed weak corporate guidance and escalating concerns over artificial intelligence spending against climbing energy prices and an upcoming interest rate decision from the European Central Bank (ECB).

The pan-European STOXX 600 index fell 0.5% to 643.47 points, with tech stocks serving as the primary anchor on the benchmark.

Key Drivers Shaping the Session

1. Technology Stocks Dragged Down by Chipmakers and Alphabet Capex

The technology sector emerged as the worst-performing segment, falling 2.7% following weak local semiconductor earnings and spillover sentiment from Wall Street:

• STMicroelectronics: Shares plunged 15% after the French-Italian chipmaker issued a Q3 revenue forecast with a midpoint below analyst expectations.

• BE Semiconductor Industries: Dropped 4.6% following the publication of its Q2 financial results.

• AI Capex Anxiety: Sentiment across global tech was further pressured after Google parent Alphabet announced a $15 billion increase in its 2026 capital expenditure plans. The aggressive spending renewed broader market skepticism regarding whether massive infrastructure outlays for artificial intelligence will yield timely returns.

2. Energy Sector Gains as Brent Crude Tops $96

Bucking the broader market downturn, the STOXX 600 Energy Index gained 0.6%.

Oil prices rallied—with Brent crude futures topping $96 per barrel—following a fresh round of U.S. military strikes on Iran and reports of Yemen’s Houthi forces targeting oil tankers in the Red Sea. The widening conflict in the Middle East continues to stoke fears of global energy supply disruptions and stickier inflation expectations.

3. Focus Shifts to ECB Rate Decision

Market participants remain cautious ahead of the European Central Bank’s policy announcement later in the day.

• Expectation: The central bank is widely expected to keep key interest rates unchanged.

• Focus: Investors will scrutinize President Christine Lagarde’s commentary and guidance for signals on the future trajectory of European monetary policy given persistent geopolitical risks and inflation trends.
