Severe Rhine navigation restrictions and depleted inventories tightened European gasoil availability in October 2026, despite refiners increasing middle distillate yields, according to Alkagesta Newsroom. Its 21 October market assessment said transport disruption constrained deliveries to Germany and Switzerland, supporting physical differentials against front-month ICE Low Sulphur Gasoil futures across Northwest Europe and the Mediterranean.
Alkagesta reported water readings at Kaub of just 1–2 cm on both 6 and 8 October, subsequently ranging around 7–18 cm. The restrictions prevented barges from loading normally and left inland distributors dependent on more expensive rail and pipeline transport. Wholesalers and end-users largely bought only for immediate requirements. Barge differentials for 50 ppm gasoil, used for heating in Germany and Switzerland, moved from a $26.75/mt discount in early October to a $10.75/mt premium by mid-month.
Inventory cover offered little protection against delivery disruption. The assessment put ARA middle distillate stocks at 2.255 million mt, 20% below their five-year average, while gasoil/diesel stocks were 1.664 million mt, down 21% year on year. The middle distillate shortfall had nevertheless eased from the 25% deficit recorded in Alkagesta’s earlier European ULSD outlook, when stocks stood at 2.108 million mt.
Seaborne supply was also affected by changing trade flows and higher freight costs. Alkagesta said clean product volumes transported on LR2 tankers fell 28% year on year to 2.1 million b/d during the first nine months of 2026. Arab Gulf-to-UK/Continent LR1 freight averaged $156.01/mt in September before reaching $220.77/mt on 19 October, compared with $46.41/mt a year earlier. Low European stocks and middle distillate deficits east of Suez drew US Gulf Coast gasoil towards Northwest European and Mediterranean ports, increasing MR1 utilisation on transatlantic routes.
Looking ahead, Alkagesta expects low stocks, secondary refinery unit maintenance and inland transport constraints to underpin middle distillate prices. It forecasts that delayed residential heating oil purchases in Germany and Switzerland could concentrate spot demand as temperatures fall, adding pressure on prompt 50 ppm and 0.1% gasoil supplies. Rhine restrictions are expected to continue until sustained rainfall improves conditions. The outlook reflects Alkagesta’s internal assessments and external information, rather than independently verified forecasts.
