European Jet Fuel Market Transitions to Surplus Amid Record Refinery Output

The European jet fuel sector underwent a significant transition in late June 2026, shifting from a period of tight availability to a prompt supply surplus. According to a market analysis by Alkagesta, a combination of record-breaking regional refinery output and a surge in global imports has effectively neutralized earlier concerns regarding a summer supply crunch. While seasonal demand from the aviation sector remains stable, the rapid accumulation of inventory has tempered the bullish sentiment typically seen during the peak travel months.

Refining activity across the continent reached new heights earlier in the second quarter as operators sought to capitalize on attractive margins. Alkagesta reports that overall production rose by 32%, with specific nations like Denmark and Hungary seeing triple-digit percentage increases in output. However, by the close of June, the economic landscape shifted as the jet-diesel regrade turned negative. This development is expected to prompt refiners to re-optimize their yields, potentially pivoting back toward diesel and gasoline production for the duration of the summer.

Inventory levels at the Amsterdam-Rotterdam-Antwerp (ARA) hub have shown signs of recovery, rising to 520,000 metric tons by late June after hitting a multi-year low earlier in the month. Despite this recent uptick, stocks remain roughly 40% below the levels recorded at the same time last year. On the demand side, while flight activity is healthy, long-term structural changes are emerging. Airlines are increasingly utilizing AI-driven route optimization and other efficiency measures to curb fuel consumption, which Alkagesta notes is limiting the total volume recovery to pre-crisis benchmarks.

Pricing for Northwest European and Mediterranean cargoes reflected this supply glut, with both benchmarks hitting their lowest points since early 2026 during the final weeks of June. CIF NWE jet fuel prices dipped as low as $912.25 per metric ton before seeing a modest recovery toward the end of the month. The physical cargo differential against ICE low-sulfur gasoil also narrowed significantly, dropping from mid-month highs of $58 per metric ton to approximately $37 per metric ton by June 29.

The shift in trade flows has been a primary driver of the current surplus. Total European imports doubled month-over-month, reaching 2 million metric tons in June. Notable contributions came from Nigeria’s Dangote refinery, which nearly doubled its exports to Europe, and Indian suppliers who diverted barrels away from Singapore to take advantage of favorable European arbitrage. Additionally, Alkagesta highlighted its own role in regional logistics, utilizing the Central European Pipeline System to deliver fuel to major hubs like Frankfurt and Brussels.

Looking ahead, the market is expected to grapple with this prompt surplus through much of July. Alkagesta anticipates that a balance between supply and demand may not be reached until late August as the peak summer travel season begins to wind down. Persistent headwinds, including permanent efficiency gains in the aviation industry and the gradual release of strategic reserves, are likely to influence the market’s trajectory through the second half of the year.
