Alkagesta Flags European Choke Point Pressures Shaping August Bunker Markets

Malta-based global commodity trading house Alkagesta has been covered by *Manifold Times* after publishing a market insight examining the dual supply crisis gripping global energy markets, as diplomatic efforts to reopen the Strait of Hormuz stall and Rhine water levels fall to record lows.

The trading house describes the situation on Europe's most important inland waterway as a "state of emergency" for fuel distribution. In an article published on Alkagesta Market Insights on 11 August, the company's trading and market intelligence teams set out how two simultaneous logistical crises are tightening prompt fuel availability across Singapore, Northwest Europe and the Mediterranean. *Manifold Times* has previously reported on the trader's fuel oil insights.

Two choke points at once

Strait of Hormuz transits fell to a near-one-month low of 13 ships on 9 August following an attack on an ADNOC-linked tanker, with both the United States and Iran seeking war reparations before any reopening agreement can be concluded. The trader had already mapped the earlier stage of that disruption in its Hormuz blockade fuel oil market outlook for July 2026, examined the wider oil supply disruption at the strait, and has since weighed reopening scenarios.

At the same time, Rhine water levels at the Kaub chokepoint fell to 16 cm on 10 August, the lowest since records began in 1880, with forecasts at the time pointing to a further drop to 4 cm by 14 August. That effectively halts barge traffic and traps fuel oil stocks at the ARA hub — a pattern also visible in the trader's European gasoline market outlook for August 2026 and its European gasoil market outlook for July 2026.

Singapore finds partial relief

The supply picture across both key hubs has deteriorated sharply, although Singapore has seen some cushioning. Middle Eastern fuel oil imports into the port nearly tripled week on week to 328,878 mt by 29 July, the highest volume since March, and onshore commercial heavy distillate stocks rose to a five-week high of 19.58 million barrels by 5 August. Alkagesta supplies the port from contracted capacity, with its Singapore marine fuel trading volumes and Horizon Terminal storage supporting delivery through the disruption; it set out its wider reading of the port in a note on Singapore marine fuels in 2026.

Demand, however, has softened. July bunker fuel sales are estimated to have fallen 3.7% month on month to 4.44 million mt, with elevated premiums redirecting prompt demand towards alternative ports including Zhoushan and Port Klang.

Europe's VLSFO market stays tight

In Europe, the VLSFO market remains acutely undersupplied as refiners continue to prioritise high-margin diesel over low-sulphur blending components. The Rhine crisis has forced barges to operate at just 15–20% of normal capacity, and freight rates from Rotterdam to Karlsruhe have risen more than 400% in two months. The trader covers the low-sulphur end of that market through its Mediterranean ULSFO business in Spain and its wider marine fuels desk, while the Maltese hub is assessed in its Malta bunkering market note for 2026.

Outlook

Alkagesta's strategic outlook points to a potential total breakdown in Rhine-linked inland distribution by mid-August, a VLSFO Hi-5 spread likely to remain above $200/mt through the third quarter, and a global crude market that analysts warn requires an additional 2.1 million b/d for 18 months to rebuild depleted inventories.

For buyers, the practical implication is that regional price signals are being set by logistics rather than by refining economics alone, and that flexibility on delivery port and grade is worth more than usual through the rest of the quarter. Storage flexibility carries a premium in that environment, as the trader's global storage operations and shipping and logistics function show.

The full insight is available in the fuel oil market outlook for August 2026, with the follow-up published as the September 2026 fuel oil outlook.
