European shares edged higher on Wednesday, holding near their highest levels in a week, as a sharp drop in crude oil prices provided macroeconomic support, while continental trading tables continued to assess hawkish central bank warnings, adopting a cautious stance while awaiting earnings results from US chip giant Nvidia Corp.

The pan-European Stoxx Europe 600 index rose 0.11%, while Germany’s DAX and France’s CAC 40 moved sideways, and Britain’s commodity-heavy FTSE 100 was held back by falling energy stocks.

Global benchmark Brent crude fell 2.6% to $86.32 a barrel, continuing a sharp 5% decline from the previous trading session.

This decline followed media reports quoting regional mediators that the United States and Iran were close to reaching a temporary truce agreement that would include guarantees for freedom of commercial navigation through the Strait of Hormuz.

Morale was also boosted by official statements from Iran and Oman confirming the resumption of bilateral talks aimed at fully reopening this vital shipping lane.

Schnabel warns of the need to raise interest rates as inflation risks persist.

In an interview with Bloomberg News published on Wednesday, European Central Bank board member Isabel Schnabel warned that borrowing costs must be raised further to control persistent price pressures, stating explicitly that the current interest rate is not sufficient to bring inflation back to the target in the medium term, and therefore further tightening will be necessary.

Schnabel noted that the ongoing conflict in the Middle East—coupled with the unexpected resilience of the broader European economy—continues to pose significant upside risks to consumer prices. Her remarks reinforce growing expectations in financial markets that the European Central Bank may raise interest rates by an additional 25 basis points in September.

The catalyst: Nvidia

Behind the headwinds from central banks, broader equity momentum remained tightly restrained, as institutional trading tables braced for Nvidia's second-quarter earnings report after the US market closed. The AI leader's quarterly report represents the most significant microeconomic test for global equity markets, with direct implications for European exchanges.

Strong results are crucial to maintaining the ratings of the local technology ecosystem in Europe, where major continental suppliers – including chip equipment giant ASML Holding NV, semiconductor manufacturers such as STMicroelectronics NV and Infineon Technologies AG, and industrial automation companies – rely heavily on sustained global demand for AI devices to feed their order books.

Meanwhile, trading tables are maintaining a defensive stance, awaiting the upcoming US PCE index data, looking for definitive signals on inflation and growth before central bankers meet at the Jackson Hole Economic Policy Symposium.
