Drought and Rhine: impacts on Swiss logistics (cross-border guide)

Context

In a nutshell

• The low level of the Rhine drastically limits the carrying capacity of the barges.
• Increased operational costs and complexities for importing fuels and raw materials.
• Germany has loosened restrictions on trucks, but the sector is calling for structural interventions.
• Long-term strategies are necessary to ensure the national energy supply.

Key facts

• What: Reduction of river navigability of the Rhine
• When: August 2026
• Where: Basel, Rhine basin and Swiss logistics arteries
• Who: Swiss Association of Shipping and Logistics Companies (Tom Odermatt)
• Challenge: Increase in transport costs and shortage risk

The drought of August 2026 reduced the draft in the Kaub section below 150 centimetres, forcing boats to travel with a reduced payload of up to 60%. For Switzerland, which imports about 10-15% of its goods and more than 30% of its petroleum products via the Rhine, the impact is severe. In Basel, the Kleinhüningen terminals signal a critical slowdown in the unloading operations of refined products.

The position of the logistics sector

River transport remains irreplaceable in terms of volume and cost, road and rail alternatives do not have the capacity to absorb the tonnage deficit caused by the dry.

According to Tom Odermatt, the buffer measures are insufficient. Germany has granted temporary exemptions to Sunday transit for trucks

Operational details

The management of water criticality requires a strategic reflection that goes beyond the meteorological contingency. Although Swiss supply is not currently at risk, the recurrence of low levels of the Rhine forces the sector to rethink the logistics architecture. The industry is pushing for durable solutions that can withstand recurring climate fluctuations. Resilience now depends on multidisciplinary coordination between logistics and authorities.

Towards a resilient logistics system

The proposals of actors such as the Chamber of Commerce of Basel City and Countryside aim at a profound modernization. The interventions requested from the Central Commission for Navigation on the Rhine focus on three pillars: infrastructure adaptation, boat innovation and digitalization.

"The stability of supplies through the Rhine is a strategic asset inseparable from the country's economic competitiveness", underline the Basel port leaders.

Small draft boats are required. Currently, a standard vessel with a draft of 2.5 meters transports about 2,500 tons; with a critical level of 1.5 meters, the capacity collapses to less than 1,000 tons, increasing transport costs by up to 300%. To mitigate this impact, the Federal Council allocated approximately CHF 15 million in 2023 for the upgrading of multimodal terminals in Birsfelden and Kleinhüningen.

Key points

Drought and the Rhine: impacts on Swiss logistics

For Swiss companies dependent on Rhine supply routes, managing logistical complexity has become a critical operational priority. Low water levels recorded in Basel, such as the historical lows below 60 centimeters reached in the summer of 2022, have paralyzed the transport of hydrocarbons and raw materials, forcing companies to revise their storage strategies. It is necessary to maintain safety reserves at least 15% above the historical average to protect production. Collaboration between the ports of Basel and land distribution centers must be strengthened through shared communication protocols to anticipate water crises. Planning must integrate climate risk as an operational cost variable.

Planning tools and procedures

To quantify the economic impact, companies must monitor intermodal transport costs, which can rise by up to 40% in the event of forced transit by rail.

Logistical resilience is not a cost, but a necessary investment for operational continuity.

Operational checklist for risk management

• Daily monitoring of Rhine water levels at the Basel-Kleinhüningen station.
• Diversification of logistics providers with at least one active rail partner.
• Review of supply contracts with specific clauses for increased logistical costs.
• Quarterly audit of critical stock levels for raw materials destined for the Basel chemical industry.

Comparison of transport scenarios

Under optimal navigability conditions, the cost per ton by barge is estimated at approximately 20-30 francs. In the event of severe drought, with limited draft, costs can exceed 100 francs per ton due to load fragmentation and the need to rely on road or rail transport, which are subject to immediate capacity limits.
