Refining margins triple while crude slides — a mismatch oil traders may regret
Supermajor earnings show product tightness that futures markets don't yet price, raising the risk of a reversal if supply disruptions persist.
A European supermajor reported adjusted net income jumped 68% year-on-year to $6 billion in the second quarter of 2026, powered by refining margins that nearly tripled from the first half of 2025. The European Refining Margin Marker rose to $12.4 per barrel, up from $4.3 a barrel a year earlier and 19% higher than the first quarter. ExxonMobil and Chevron also reported their highest earnings in years during the week of August 3, drawing criticism from President Trump, who said they are making "too much money."6
NYMEX WTI crude front-month has been sliding for weeks, settling at $75.92 per barrel on Thursday (2026-08-06), down sharply from late-July levels near $84.67. ICE Brent crude front-month closed at $79.93, well below its July peak near $88.5
The narrative among traders has centred on demand fears and the expectation that Middle East production disruptions would ease by year-end. The EIA forecast global oil output would return to pre-conflict levels by the end of 2026, implying that the supply shock — which peaked near 10.8 million barrels per day in May — would fade.4,3
Three developments suggest the physical market is tighter than futures prices reflect.
Refining margins are behaving like the product shortage is structural, not temporary. If refiners expected crude to stay cheap and products to weaken, they would not be locking in capacity expansions or posting these returns.6
US crude export flows in May hit a record 5.6 million barrels per day, up from 5.2 million in April, according to Kpler. Asian buyers took 2.45 million barrels per day, the highest on record, while European flows also reached new peaks. NYMEX WTI crude traded at a steep discount to ICE Brent through May and June, which opened an arbitrage window.2
Yet Signal Maritime reported seeing at least 10 fewer VLCCs fixed for June loadings compared with May, and analysts at Vortexa noted that low US crude inventories would pull more barrels into domestic storage rather than exports. If the export surge was a brief arbitrage play rather than sustained demand, the discount should have closed faster. It did not.2
The spread between NYMEX WTI and ICE Brent widened sharply in late May. On Tuesday (2026-05-26), Brent July delivery gained 3.16% to trade at $99.18 per barrel, while WTI fell, an unusual divergence from their typical lockstep movement. The pattern suggested that physical buyers in Asia and Europe were willing to pay up for non-US grades even as WTI weakened on domestic oversupply fears.1
Refiners are running hard, margins are strong, and export demand for processed fuels — diesel, jet fuel, LPG — is firm. Rising global demand for alternative supply has boosted US exports across the barrel, reinforcing WTI's growing role in international pricing.3
If the market is wrong, and refining economics stay tight into the fourth quarter, NYMEX WTI crude could rally despite oversupply headlines. The EIA's forecast of production returning to pre-conflict levels assumes no new disruptions and smooth restarts in the Persian Gulf and Black Sea. Neither is guaranteed.4,5
The Caspian Pipeline Consortium held discussions on Friday (2026-07-31) about whether to halt shipments indefinitely; it ultimately decided to continue operations. Had it stopped, another 1.2 million barrels per day would have come off the market.5
The data point to watch is US product exports in June and July. If diesel and gasoline flows hold near May levels despite fewer VLCC fixtures, it confirms refiners are prioritising margin over crude price signals and that physical tightness is real.
