Malta-based commodity trading house Alkagesta has published its August 2026 fuel oil market outlook, titled Choke Point Pressures, arguing that two simultaneous logistical crises — a stalled diplomatic process around the Strait of Hormuz and record-low water levels on the Rhine — are tightening prompt fuel availability across the world's largest bunkering and distribution hubs.
According to the insight, published by Alkagesta on 11 August 2026, transits through the Strait of Hormuz fell to a near one-month low of 13 ships on 9 August following an attack on an ADNOC-linked tanker, with both Washington and Tehran demanding war reparations before any reopening agreement can be reached. Alkagesta frames that impasse as a structural rather than temporary feature of the current market.
The second pressure point is inland European distribution. Alkagesta reports that Rhine water levels at the Kaub choke point 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 about 4 cm by 14 August. At those levels barge traffic effectively halts, stranding fuel oil barrels at the Amsterdam-Rotterdam-Antwerp hub rather than moving them to inland demand centres.
On supply, the Alkagesta outlook notes that Middle Eastern fuel oil imports into Singapore nearly tripled week on week to 328,878 mt by 29 July — the highest volume since March — helping lift onshore commercial heavy distillate stocks to a five-week high of 19.58 million barrels by 5 August. Even so, July bunker sales in Singapore are estimated to have fallen 3.7% month on month to 4.44 million mt, with elevated premiums redirecting prompt demand toward Zhoushan and Port Klang.
In Europe, Alkagesta describes the VLSFO market as acutely undersupplied, with refiners continuing to prioritise high-margin diesel over low-sulphur blending components. The Rhine crisis has compounded that shortage: barges have been operating at roughly 15-20% of normal capacity, while freight rates from Rotterdam to Karlsruhe are reported to have risen more than 400% in two months.
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 hold 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 bunker buyers, the practical consequence is that hub-level stock builds no longer guarantee prompt availability. When inland barge capacity and long-haul arbitrage are constrained at the same time, physical delivery risk — not headline flat price — becomes the binding constraint on procurement.
The full outlook is published on Alkagesta's Market Insights channel, and was subsequently summarised by bunkering trade title Manifold Times on 17 August 2026.
