The S&P Composite 1500 Oil & Gas Refining & Marketing Index rose 141% in 2026, driven by record profits during the second quarter. These gains occurred as geopolitical conflicts constrained global energy supplies, prompting increased investor interest in the sector.
Why it matters
Refiners operate as price takers, making their margins highly sensitive to global supply disruptions caused by wars in the Middle East and Ukraine. The current market pricing assumes these fundamental conditions will persist, creating potential downside risk for businesses reliant on these suppliers.
The S&P Composite 1500 Oil & Gas Refining & Marketing Index finished 141% higher in 2026, trading 63% above its 200-day moving average. Analysts now project that major industry players including Valero Energy Corp., Marathon Petroleum Corp., and Phillips 66 will face an 18% earnings decline in 2027.
The players
Valero Energy Corp.
A major independent petroleum refiner and ethanol producer with significant market scale.
Marathon Petroleum Corp.
A leading U.S. downstream energy company operating one of the nation's largest refining systems.
Phillips 66
A diversified energy manufacturing and logistics company with global refining and midstream operations.
The details
Refiners have seen record performance through the third quarter of 2026, bolstered by constraints such as China's clean fuel export curtailments initiated in mid-March. The sector currently exhibits a weekly relative-strength index above 80, a signal that historical data suggests often precedes a correction. Because these firms act as price takers, their operations fluctuate directly with external crude oil and fuel market dynamics.
Timeline
Mid-March 2026: China curtailed clean fuel exports.
Q2 2026: Refinery companies recorded peak profits.
July and August 2026: VanEck Oil Refiners ETF experienced increased inflows.
2027: Analysts project lower earnings for major refiners.
Market Landscape
This rally follows the pattern set by the 2022 energy market supply shocks, where geopolitical conflict directly dictated downstream profitability. The current index performance reflects a trend of pricing in supply scarcity that historically faces correction once risk premiums subside.
Operators should prepare for persistent price volatility in refined fuel inputs as the market prices in significant geopolitical risk. Factor in the projected 2027 earnings downturn when negotiating long-term fuel procurement contracts to account for potential normalization in supply costs.
The takeaway
The sector has reached extreme valuation levels, signaled by a relative-strength index above 80 and record quarterly profit growth. Operators should track the geopolitical risk premium in fuel prices as a lead indicator for when market earnings may begin to revert to 2027 projections.
