European energy equities advanced Tuesday following an uptick in violence across the Middle East that sent crude oil prices to their loftiest levels since late July.
By 04:09 ET (08:09 GMT), Brent crude futures had risen 2.1% to $99.93 a barrel. U.S. West Texas Intermediate crude climbed 1.4% to $94.31 a barrel. A renewed push toward the $100-a-barrel threshold would come at a sensitive time, with markets already coping with inflationary pressures for much of the year.
The STOXX Europe 600 Oil & Gas Index gained 0.8%, leading sector moves across the broader Stoxx 600 gauge.
On an individual stock level, several large European names posted notable advances. TotalEnergies, Eni, Neste and Galp Energia each rose in a band between 1.2% and 1.9%. Maurel & Prom edged up 0.8%, Equinor climbed 3.1%, and Repsol added 2.1%. Shell and BP rose 1.2% and 1.8%, respectively.
The market reaction followed a sharp escalation in hostilities. Iranian-backed Houthi forces in Yemen launched strikes on several Saudi cities, drawing a key U.S. ally further into the ongoing six-month conflict. U.S. forces responded by striking multiple Iranian oil tankers, while Iran struck a U.S. base in Jordan and attacked shipping vessels.
These episodes increase the risk of deeper disruptions to oil supplies from the region, which had already been under strain from attacks on energy infrastructure and key shipping lanes.
Brent crude has advanced by roughly a quarter since early August, a move that coincided with diminishing hopes for a lasting resolution to the conflict and the resumption of sustained fighting.
Market participants watched both commodity and equity moves closely, as further supply shocks or expanded regional involvement could amplify price volatility and ripple through sectors sensitive to energy costs.
