STOXX 600 rises on tech strength; oil and bond yields remain a drag

On Tuesday, European shares experienced a modest increase, driven by the performance of technology stocks, despite the impact of higher crude oil prices and elevated bond yields. The STOXX 600, a pan-European index, rose by 0.3% to 640.28 points by 0830 GMT. Technology shares were the primary movers, reaching their highest level in a month.

Semiconductor stocks saw a boost following a Reuters report that AI-focused firm Anthropic is planning a significant expansion, potentially valued over $2 trillion through an upcoming stock market listing.

This excitement around AI IPOs reignited the sector, which had been struggling following the AI companies' calls for a slowdown due to concerns about misuse. Earlier in the month, executives from several major AI firms had advocated for a more measured approach to development, which had weighed on technology stocks already facing pressure from rising bond yields.

Global bond yields remained near multi-decade highs due to investors' concern over inflation risks stemming from rising energy costs. Brent crude futures stayed at $106.99 a barrel as the Middle East conflict continued without a resolution, causing oil prices to climb.

European economies are particularly sensitive to surging energy prices due to their heavy reliance on imported fuel. ECB President Christine Lagarde stated on Monday that inflation's surge this year has not yet translated into second-round effects across the euro zone, indicating that a measured policy response is still warranted. The ECB had raised interest rates earlier in the month.

Among individual stocks, Lindt experienced a decline of roughly 7%, marking the STOXX's largest drop among the index's components. The Swiss chocolatier reduced its 2026 sales forecast for the second consecutive time, citing subdued consumer sentiment, heightened price sensitivity, and weak demand during a European heatwave. Peers Barry Callebaut and Nestle also faced pressure.

In contrast, Julius Baer led the gains, increasing by 7.7%. This rise came after Switzerland's financial regulator, FINMA, concluded enforcement proceedings related to private debt loans and client ties to two politically exposed Russian individuals. Shares of Legrand surged 7.3% after the French electrical and digital building infrastructure group raised its medium-term targets.
