Why Rhine Drought Left Eastern France Short of Fuel

Service stations across eastern France began running short of fuel on Friday 14 August as drought left the Rhine too shallow for normal barge traffic. According to the government's fuel-price monitoring site, 14% of stations in the region were classified as "in difficulty", meaning they had run out of at least one fuel. In Haut-Rhin and Territoire de Belfort, between 25% and 50% of stations were unable to supply at least one type of petrol, with unleaded particularly affected.

The immediate trigger is the water level in the river's navigable channel at Kaub, in western Germany. On Monday it fell to 130 centimetres, a level described by Voies navigables de France as never previously reached. Jean-Laurent Kistler, VNF development director in Strasbourg, said barges are being forced to cut their cargoes by about 80%, throttling fuel deliveries into eastern France.

The supply crunch is now visible at the pump. An employee at a TotalEnergies station in Strasbourg said the situation had lasted about a week, with SP98 out of stock, and recommended that drivers fall back on SP95. Some stations, however, have neither fuel available. Rain is expected from the weekend into next week, but Kistler cautioned that the Rhine may regain only about 20 centimetres before falling again.

Similar disruptions hit eastern France in 2018 and 2023. This year, according to VNF, the rainfall deficit began very early, at the start of July rather than in September, making the episode more severe than those earlier droughts.

Inside the Rhine Bottleneck: Kaub, Barge Loads and a Repeating Crisis

The 130cm Kaub Gauge and the 80% Load Cut

The Rhine is a major artery for fuel supply into eastern France, and Kaub is a critical measurement point for navigable depth. At 130 centimetres, barges cannot operate with normal drafts. The fact that cargoes are being reduced by 80%, as stated by VNF, means each trip delivers roughly one-fifth of a normal load, so stations cannot be restocked at their usual rhythm. This is a physical capacity problem rather than a shortage of fuel in refineries.

Why Haut-Rhin and Belfort Show the Sharpest Shortages

The government data showing 25–50% unavailability in these two departments points to a downstream supply squeeze concentrated in areas reliant on Rhine-linked deliveries. The scarcity of unleaded fuel in particular suggests that the disruption is hitting high-turnover petrol grades first, while some stations have lost both SP95 and SP98.

A Recurring, Climate-Sensitive Bottleneck

The same vulnerability produced supply problems in 2018 and 2023. What makes the current episode stand out is timing: VNF says the precipitation deficit began at the start of July rather than the usual September. The rain forecast for next week is expected to lift the river by only around 20 centimetres before levels fall again, so the logistics constraint may ease temporarily but is unlikely to disappear.

What Drivers and Fuel-Dependent Businesses in Eastern France Can Do

  • Check live fuel availability before travelling in Haut-Rhin and Territoire de Belfort. With 25–50% of stations lacking at least one fuel, the government's prix-carburants.gouv.fr site is currently the most practical tool for finding stocked stations.
  • Use SP95 where your vehicle permits it if SP98 is unavailable. A Strasbourg TotalEnergies station has been directing customers from SP98 to SP95; drivers should confirm compatibility with their vehicle manual.
  • Expect restocking to remain uneven through next week. VNF expects rain to raise the Rhine by only about 20 centimetres before levels fall again, so barge deliveries will stay constrained.
  • Fleet operators and fuel-dependent businesses should fill vehicles when supply is available and plan routes around known shortages. With barge cargoes cut by 80%, replenishment cycles are much longer, even though the situation is not yet described as dramatic.

Risk & Opportunity Assessment

Commercial RiskMediumFuel distributors and service station operators in eastern France face lost sales and logistical strain while the Rhine remains shallow: 14% of stations are in difficulty, with up to 50% unavailable in Haut-Rhin and Belfort.
Competitive RiskMediumStations that manage to keep both unleaded fuels in stock can capture short-term demand from competitors that are out of SP95 or SP98, though the shift is likely temporary.
Regulatory RiskLowNo regulatory intervention has been announced; the government fuel-price website is currently acting as a monitoring tool rather than a policy response.
Reputation RiskLowLocal service stations may face motorist frustration, although a Strasbourg TotalEnergies employee described the situation as not yet dramatic.
Technology DisruptionLowNo technology shift is driving the disruption; it is a climate and waterway constraint on conventional fuel logistics.
Commercial OpportunityMediumOperators with available stocks and better inventory positions can gain market share while river-dependent deliveries are cut by about 80%.
