European stock markets opened mostly lower on Tuesday as renewed tension between the United States and Iran pushed oil above $91 a barrel and drove government borrowing costs to multi-year highs. London resisted the broader decline with support from energy companies, while Frankfurt, Paris and Milan weakened as technology and industrial shares came under pressure.
Regional benchmark slips at the opening
The pan-European STOXX 600 fell approximately 0.2% to 654.81 during the opening period. The decline followed losses across major Asian markets and a weaker finish on Wall Street, where investors had responded to higher oil prices and rising US Treasury yields.
Energy shares gained around 0.6% as Brent crude advanced to approximately $91.40 a barrel. Basic resources companies moved in the opposite direction, falling about 1% as higher bond yields and a stronger dollar placed pressure on metals and mining shares.
London receives support from oil companies
The FTSE 100 opened at approximately 10,750, above Monday’s close of 10,720.30. The index remained marginally positive during early trading as gains for major oil producers helped offset weakness elsewhere.
BP and Shell benefited from higher crude prices, giving London an advantage over markets with heavier exposure to technology and manufacturing. Mining shares were less supportive as gold and several industrial metals weakened.
Investors were also assessing British employment data, which indicated continued cooling in the private labour market. Slower wage growth could reduce pressure on the Bank of England, although higher energy costs may complicate the inflation outlook.
Frankfurt falls as borrowing costs increase
Germany’s DAX opened at 26,294.67, approximately 0.2% below Monday’s close, before extending its decline. Technology and industrial companies led the weakness, with semiconductor manufacturer Infineon and engineering group Siemens among the early fallers.
Germany’s ten-year government bond yield climbed to its highest level since 2011. Higher yields increase financing costs and reduce the relative appeal of companies whose valuations depend heavily on future earnings.
The combination of more expensive energy and higher borrowing costs represented a particular concern for Germany’s manufacturing-intensive economy.
Paris follows the regional decline
France’s CAC 40 opened around 8,563 points and moved approximately 0.2% lower. Technology company STMicroelectronics and industrial group Schneider Electric were among the stocks weighing on the index.
France’s ten-year government bond yield reached its highest level in 16 years as investors responded to global inflation concerns and increased government borrowing requirements. Luxury and consumer companies also traded cautiously amid uncertainty about international demand.
Milan retreats while Madrid holds firm
Italy’s FTSE MIB declined around 0.4% during early trading, with banking, technology and industrial shares under pressure. Rising eurozone yields created a mixed environment for banks, potentially improving lending margins while also increasing credit and sovereign debt risks.
Spain’s IBEX 35 opened close to 19,991 and edged approximately 0.1% higher. Gains for energy producer Repsol helped Madrid avoid the broader European decline.
Geopolitical risk dominates the outlook
Brent crude rose for a third consecutive session after the temporary US-Iran ceasefire expired without a permanent settlement. Investors remained concerned about restricted tanker traffic through the Strait of Hormuz and the possibility of further disruption to global energy supplies.
European markets now face competing forces. Higher oil prices support energy producers but threaten to increase inflation, household costs and pressure on interest rates. The opening therefore reflected cautious positioning rather than a broad sell-off, with investors waiting for diplomatic developments and the US Federal Reserve’s July meeting minutes.
