Oil Prices Fall After Trump’s Remarks on Iran

Falling crude oil prices were among the main factors supporting European equities on Friday. US President Donald Trump said Washington would not attack Iran before next month’s US midterm elections and described discussions with Tehran as “productive”.

The comments helped ease immediate fears of a further escalation in the Middle East and potential disruption to oil supplies through the Strait of Hormuz. Brent crude had risen above $104 per barrel on Thursday amid concerns about attacks on shipping in the Gulf and possible supply interruptions. Prices subsequently retreated in early Friday trading.

Lower oil prices can help reduce concerns about energy-driven inflation and the possibility of interest rates remaining high for longer. However, the situation remains uncertain, and renewed geopolitical tensions could push crude prices higher again.

The broader European market also advanced, with the STOXX Europe 600 rising around 0.8% at the open. Falling oil prices and easing bond-market volatility helped improve investor sentiment. 

Software Stocks Lead FTSE 100 Gains

Software and information-services stocks are among the notable gainers in Friday trading. Sage Group rose around 4%, while RELX advanced approximately 3.2%, according to the reported market movements.

The gains helped support the broader UK benchmark as investors bought selected technology-related and growth stocks following the previous sessions’ declines.
