Energy stocks weakened on Monday as global oil benchmarks moved sharply lower after the United States and Iran paused military strikes over the weekend.
The S&P 500 energy index declined 1.5% as Brent crude futures plunged 6.9% to $90.03 per barrel. U.S. West Texas Intermediate fell 6.4% to $83.51 per barrel, leaving crude markets around a one-week low.
Market participants attributed the pullback in prices to hopes that the cease in strikes could pave the way for diplomacy and ease tensions that have threatened shipping lanes, particularly the Strait of Hormuz. However, traders and analysts noted that the pause has not yet translated into increased vessel movements through the strait, tempering expectations of a rapid return to pre-conflict conditions.
"There has been no increase in shipping traffic through the Strait of Hormuz, and as such we see this showing the selloff in crude remains overdone as a return to 'normalisation' continues to look remote in near term," Panmure Liberum analyst Ashley Kelty said.
Within the energy index, pipeline companies were among the largest percentage decliners. ONEOK (NYSE:OKE), Kinder Morgan (NYSE:KMI), Williams Companies (NYSE:WMB) and Targa Resources (NYSE:TRGP) each fell in a range between 2.4% and 2.9%.
Major integrated oil companies also retreated, with Exxon Mobil (NYSE:XOM) down 1.4% and Chevron (NYSE:CVX) off 1.7%.
Independent oil producers were not spared: Occidental Petroleum (NYSE:OXY), Devon Energy (NYSE:DVN), APA Corp (NASDAQ:APA) and Diamondback Energy (NASDAQ:FANG) recorded declines between 1.9% and 2.4%.
The move lower in crude came even as some market observers cautioned that visible signs of resumed shipping or sustained de-escalation remain limited. That mix has left oil prices sensitive to shifts in geopolitical headlines, while energy equities tracked the commodity's slide.
Investors will likely continue to monitor both crude benchmarks and indicators tied to shipping and regional stability for signals that might reverse or reinforce the recent selloff.
