Energy stocks in 2026 have staged a remarkable rally that has made the sector the undisputed leader among S&P 500 groups. The Energy Select Sector SPDR Fund (XLE) has surged more than 28% year-to-date through mid-May, driven by West Texas Intermediate crude trading near $106 per barrel and a historic supply crisis triggered by the closure of the Strait of Hormuz. With Middle East production disruptions removing roughly one-fifth of global seaborne crude supply, energy equities are delivering returns that dwarf every other corner of the market.
The rally marks a dramatic reversal from the sector's underperformance in late 2025, when recession fears and talk of peak oil demand weighed on energy names. Now, a combination of geopolitical supply destruction, disciplined capital spending by major producers, and generous dividend payouts has turned energy into the must-own trade of the year.
What Happened
The energy sector's dominance traces directly to the February 28, 2026 escalation when coordinated U.S. and Israeli airstrikes on Iran triggered the closure of the Strait of Hormuz, the narrow waterway through which roughly 20% of the world's seaborne crude oil and liquefied natural gas had flowed before the crisis. The International Energy Agency has called it the largest supply disruption in the history of the global oil market, and the strait remains effectively closed as of mid-May despite a formal ceasefire since early April.
The closure shut in production from Iraq, Saudi Arabia, Kuwait, the UAE, Qatar, and Bahrain, collectively removing approximately 10.5 million barrels per day from efficient market access. WTI crude surged from roughly $66 per barrel at the start of the year to $106.42 by early May, a gain of more than 60%. Brent crude has tracked a similar trajectory. The IEA warned this week that global oil markets could remain severely undersupplied until October even if the war ends next month, as only limited tanker traffic has resumed through the strait.
U.S. oil majors have been the primary beneficiaries. Exxon Mobil, which makes up roughly 22% of the XLE ETF, has seen its shares climb past $157, supported by disciplined capital expenditure and a strong free cash flow profile at current crude prices. Chevron has rallied to the $190 range with a dividend yield of 3.8%, while ConocoPhillips trades above $121. The S&P 500 Energy sector posted a record 14-week winning streak, the longest in the sector's history, before a modest pullback in mid-May.
