Investors are bracing for an ECB rate hike on Thursday. Markets expect the European Central Bank to raise rates by 25 basis points, which could weigh on growth and corporate earnings. Investors are also awaiting guidance on whether further hikes will follow.

ING said in an analysis on Thursday morning that: "We expect the ECB to hike by 25 basis points from 2.0% to 2.25%, supported by a hawkish tone, but the bar has risen to surprise markets. Despite oil prices testing new lows earlier this week, the EUR curve is increasingly set on three rate hikes."

Stock markets across Europe opened in positive territory despite the drop in Asian shares following another sell-off in AI-related stocks on Wall Street on Wednesday.

The Euro Stoxx 50 opened 1.2% higher but the broader pan-European Stoxx 600 rose was flat in early trading.

Germany's Dax and France's CAC 40 were both up by 1%, while the UK's FTSE 100 led with a 1.2% gain. Meanwhile, Italy's FTSE MIB rose by 0.7%.
