US energy stocks surged Wednesday as Iran's renewed attacks on commercial shipping in and near the Strait of Hormuz, followed by President Trump's declaration that the US-Iran ceasefire was 'over,' abruptly reversed the de-escalation trade that had deflated energy equities through much of June. ExxonMobil rose 1.6%, Chevron advanced 1.9%, and ConocoPhillips climbed 2.2% in early trading, with the Energy Select Sector SPDR fund one of the only bright spots in a broadly lower US equity market.
The energy sector's sharp turn higher on Wednesday stands in stark contrast to its trajectory following the June ceasefire agreement, when the announcement that the Strait of Hormuz would reopen drove crude oil sharply lower and sent energy stocks into a prolonged slide. ExxonMobil and Chevron both had been 2026's top-performing S&P 500 stocks through the first quarter, rising 41% and 36% respectively while the broader index fell, riding the war premium that pushed Brent crude to an average of around $120 per barrel in April according to IEA data. The June de-escalation and the Treasury's General License X, a sweeping authorization allowing buyers worldwide to purchase Iranian crude, had significantly eroded that premium.
Wednesday's reversal restores at least a portion of the supply-risk premium that had been priced out of crude markets over the past several weeks. West Texas Intermediate rose 4.9% to $73.89 per barrel, while Brent crude jumped 5.2% to $78.02. The US Treasury separately revoked a waiver that had allowed Iran to sell oil on the global market, a policy move that analysts said could meaningfully tighten the crude supply outlook if enforced and sustained. The prior waiver, General License X, was set to expire August 21, so its early revocation removes roughly six weeks of expected Iranian supply from global market calculations.
Analysts noted that the fundamental case for oil majors in a renewed escalation scenario goes beyond crude prices alone. Higher oil prices also benefit refining margins, chemicals, and LNG pricing, giving integrated majors like ExxonMobil — which generated $52 billion in operating cash flow in 2025 — diversified earnings leverage across the commodity complex. ExxonMobil's Guyana and Permian Basin operations have been running at record production levels and are among the lowest-cost barrels globally, meaning the company captures outsized benefit from any move in oil prices above its operating breakeven.
The comparison between the two Dow components has also sharpened. ExxonMobil's production hit a 40-year high of 4.7 million barrels of oil equivalent per day in 2025, while Chevron posted record production of 3.7 MBOED. Chevron faces some additional near-term uncertainty due to its Venezuela exposure and ongoing legal headwinds, while ExxonMobil's more extensive downstream and chemicals footprint provides a partial natural hedge when crude prices move sharply in either direction.
ConocoPhillips, as a pure-play exploration and production company without refining or chemicals operations, has the most direct and concentrated leverage to crude prices of the three, making its gain on Wednesday particularly representative of how the market is immediately responding to the renewed supply-risk premium. The company has budgeted approximately $12 billion in capital expenditures for 2026 and had been pursuing cost savings through its Marathon Oil acquisition synergies, positioning its cost structure to remain competitive across oil price scenarios.
Oilfield services giant SLB and pipeline operators are also tracking higher, while airline and transportation stocks — which had benefited from the June de-escalation and lower jet fuel costs — are reversing those gains as the supply-disruption trade returns.
