European stocks close 1.5% higher after ECB hikes interest rate to record 4%

The pan-European Stoxx 600 index closed around 1.61% higher at 4.30 p.m. London time after the European Central Bank hiked interest rates to a record level.

The ECB raised rates by 25 basis points, bringing the central bank's main deposit facility to 4%. It was at -0.5% in June 2022, before the bank started its rate increases.

The European Central Bank is likely to impose a "dovish" interest rate hike on Thursday, according to JPMorgan Asset Management's Iain Stealey. But he warned the central bank must be wary of a potential policy error.

"I feel it is going to be more towards the dovish hike," Stealey told CNBC's "Street Signs Europe" ahead of the ECB's meeting.

His comments come at a time when expectations for Thursday's policy meeting are split between a so-called "hawkish pause" and a "dovish hike." Some traders expect ECB policymakers to hold interest rates steady, while others anticipate a 25-basis-point increase.

"It does feel that they want to hike but when you look at the economic data, it does smell of a possibility of policy mistakes and I think they'll want to be clear around the fact that, you know, we are seeing weakness," Stealey said.

Adam Kostyál, head of listings for Europe, Middle East and Africa at Nasdaq, discusses the significance of Arm's initial public offering and Instacart's upcoming one.

European autos stocks fell 1.2% Thursday morning, leading sector losses, as a retaliatory fight over electric vehicle subsidies threatened to break out between the European Union and China.

The EU on Wednesday announced an investigation into subsidies given to EV-makers in China, with European Commission President Ursula von der Leyen saying Europe was "open to competition but not for a race to the bottom."

She told lawmakers, "Take the electric vehicle sector, it is a crucial industry for the clean economy with a huge potential in Europe, but global markets are now flooded with cheaper Chinese electric cars and their prices are kept artificially low by huge state subsidies."

China soon hit back, with the moves criticized by the secretary-general of the China Passenger Car Association and the Ministry of Commerce, raising the specter of retaliatory tariffs.

Investors will also be monitoring developments in the United States, where a widespread auto workers strike may be called at the end of Thursday.

European stock markets were cautiously higher early Thursday, with the European Central Bank's monetary policy decision due this afternoon on a knife-edge.

The euro was cautiously higher against the U.S. dollar Thursday morning after hitting a three-month low against the greenback, as U.S. inflation data failed to shift market expectations for a pause in Federal Reserve rate hikes.

The euro was up by 0.15% to $1.074 at 8:30 a.m. Frankfurt time. The EU currency was also 0.1% higher against the British pound, at 0.859.

Opinions are split on whether the European Central Bank will announce a rate hike at 2:15 p.m. Frankfurt time, with markets pricing in a roughly 64% probability of a hike — up from around 40% in recent days.

It marks a shift for the central bank, which in prior meetings has given a much firmer indication of its actions ahead of decision day.

"The ECB has moved to a data-dependent approach and, as such, is likely to be influenced by the deceleration in price pressures highlighted in August's inflation report and the lacklustre level of gross domestic product growth (0.1%) in Q2," Henk Potts, market strategist at Barclays Private Bank, said in a note.

"Expectations of stagnating economic activity and inflation returning towards the ECB's 2% inflation target in 2024 may mean the central bank will keep rates on hold this week. Furthermore, in our view the Governing Council is likely to keep policy rates on hold through to the middle of 2024, with July's rate rise proving to be the final hike of this cycle."
