Low Rhine Water Threatens Swiss Supply Chains and Could Push Up Prices

The Rhine fell to 6 centimetres at Kaub in August, cutting into one of Switzerland’s most important freight routes. The German measuring point sits on a heavily used stretch of river that links Rotterdam’s port complex with Basel and the wider Swiss economy. When water levels drop, vessels must reduce their loads to avoid grounding. Some freight then moves to roads and railways, both of which have limited spare capacity.

The disruption reaches far beyond shipping companies. Fuel, grain, animal feed, gravel and cement all depend on economical bulk transport. A large inland vessel can carry roughly 100 times as much as a lorry, with fewer workers. Removing that capacity forces shippers to pay more for replacement transport, reschedule deliveries or leave cargo waiting at ports and terminals.

The Rhine was not the only European river affected. The Danube in Hungary and Romania, Italy’s Po and France’s Loire also reached exceptionally low levels. For Swiss importers, the immediate concern is the cost and reliability of goods arriving through Basel. A longer disruption could affect petrol stations, construction sites, food processors and retailers at the same time.

A river cargo vessel can carry about 100 times the freight of a lorry, which makes replacement transport expensive and difficult. At low water, vessels cannot load to their normal draft. Operators may split one shipment across several trips, use smaller craft or transfer cargo before it reaches Basel.

The cost rises fastest for heavy and bulky goods. Sand, fuel and grain have low value relative to their weight, so transport charges represent a significant share of the final price. There are few cheap alternatives when river capacity disappears. Road haulage can take the cargo, but each additional truck consumes fuel, drivers and road space. Rail can absorb part of the volume, although available paths, terminals and rolling stock are finite.

The pressure is already visible in fuel logistics. Julia Arlinghaus, a professor of logistics and supply-chain management at the University of St Gallen, said road transport became markedly more expensive during the summer. At times, moving fuel from Rotterdam to Basel cost ten times more. Swiss companies can negotiate, delay or seek other suppliers, but those measures rarely erase the underlying freight bill.

Transport bottlenecks may have added about 16 centimes to a litre of fuel, almost 8% of the cost of filling a tank. Arlinghaus told Le News that the effect reached Swiss petrol stations as the cost of moving fuel from Rotterdam to Basel climbed. The figure does not mean every station or shipment faced the same increase. Energy prices, taxes, exchange rates and local competition also shape the price displayed at the pump.

The Rhine disruption can still pass through the economy in several ways. Fuel distributors may pay more for alternative haulage, while wholesalers face delays and extra handling charges. Retailers then decide whether to absorb those costs or reflect them in prices. Businesses that operate vans, trucks, machinery and heating systems feel the effect before households see it in shops.

Food supply chains face a similar exposure. Grain and animal feed move in large volumes on inland waterways. Higher freight costs can therefore reach bakeries, farms and meat producers, eventually affecting bread, eggs and meat. Construction faces its own pressure from the cost of transporting gravel and cement. The final price impact is difficult to isolate, but the logistics shock adds another cost to already volatile markets.
