European shares muted as investors assess Iran-Oman talks, US inflation

European shares experienced a lackluster performance on Wednesday (August 26), as investors closely monitored discussions between Iran and Oman regarding the Strait of Hormuz. The waterway, which accounted for a fifth of global oil and gas shipments prior to the US-Iran conflict, remained a point of uncertainty. A senior Iranian source stated that while Tehran and Oman were still fine-tuning the details of an agreement, the talks offered hope for a resolution.

However, Van Leenders, a senior investment strategist at Van Lanschot Kempen Investment, cautioned that the uncertainty was perceived more as a risk than an incorporation into forecasts. The reopening of the waterway depended on the US meeting Iran's conditions.

While crude prices had dipped below US$90 a barrel in recent days, elevated petrol and refined oil product prices continued to dominate inflation concerns in Europe. The pan-European Stoxx 600 index closed 0.01 percent lower at 656.41 points. Despite facing an energy shock, the European economy had proven resilient, which bolstered investor optimism.

In the United States, a hotter-than-anticipated Personal Consumption Expenditure report, the Federal Reserve's preferred inflation gauge, marginally increased expectations for a rate hike in September. The Stoxx 600 index in the US showed gains for European banks, with Deutsche Bank rising 4.3 percent to its highest level since July 2011 and Commerzbank increasing 2.8 percent.

German Finance Minister Lars Klingbeil planned to meet UniCredit CEO Andrea Orcel, marking the first direct engagement between the two on UniCredit's pursuit of Commerzbank.

The European Central Bank policymakers were prepared to raise interest rates at their September meeting to address the economic impacts of the Iran conflict, though they were hesitant to signal any further tightening beyond that, according to three sources. Investors also awaited Nvidia's second-quarter earnings to gain insights into whether the AI-driven spending boom could sustain lofty market expectations.

Tech shares declined by 0.8 percent, while healthcare shares led losses, falling 1 percent. Among individual stocks, Britain's Hochschild Mining experienced a 5.4 percent rise, among the top gainers on the benchmark, as a surge in gold prices throughout the year boosted first-half revenues. SAP declined by 2.9 percent, marking the biggest drag on the benchmark, following a disappointing US software maker Intuit forecast. UBS downgraded the German software group to "neutral."
