Swiss petrol prices reach a new yearly high

Swiss drivers are paying more than CHF 2 per litre for standard petrol. The average price of unleaded 95 reached CHF 2.10 per litre on September 16, 2026, according to the Touring Club Switzerland. That is 5 centimes more than a week earlier and the highest average recorded this year.

The increase affects every major fuel grade. Unleaded 98 now averages CHF 2.21 per litre, while diesel stands at CHF 2.38. Diesel has recorded the sharper rise over the year, climbing by around 33% since January, compared with approximately 27% for petrol.

The figures put Switzerland close to the levels seen during the fuel shock that followed Russia's invasion of Ukraine. Unleaded 95 reached CHF 2.31 per litre in 2022, while diesel peaked at CHF 2.40. The current diesel price is only 2 centimes below that previous maximum.

For motorists, the change appears each time they fill a tank. For companies that depend on vans, lorries or machinery, the increase feeds directly into operating costs. The latest move also arrives with no clear indication that prices will stabilise soon.

Three international price signals shape what Swiss motorists see at the pump: Rotterdam, the dollar and Rhine freight. Switzerland does not price fuel in isolation. The Touring Club Switzerland says the main drivers are the wholesale prices for refined products traded through the Rotterdam market, the exchange rate against the US dollar and the cost of transporting fuel along the Rhine.

Rotterdam prices matter because Switzerland relies on imported refined products and is closely connected to European supply chains. A rise in the international price of petrol or diesel can therefore reach Swiss stations even when domestic demand has not changed sharply. The dollar adds another layer. Oil and many petroleum products are traded in US dollars, so currency movements can raise the franc cost of imports.

Freight rates also affect the final calculation. Fuel transported up the Rhine faces shipping costs that can change with river conditions, capacity and market demand. Those costs are passed through the supply chain before fuel reaches storage facilities and petrol stations.

The combination makes the Swiss pump price sensitive to events well beyond the forecourt. Retailers may adjust prices as wholesale and transport conditions move, while the impact reaches consumers with a delay.

The latest surge is unfolding against a strained refining market and a rising crude price. Keystone-SDA reported that experts attribute part of the current pressure to refinery capacity destroyed in the wars in Iran and Ukraine. Damage to refining infrastructure can restrict supplies of finished petrol and diesel, even when crude oil remains available.

That distinction matters for Switzerland. Petrol stations sell refined products, and the price of those products depends on regional availability as well as the cost of crude. A tighter market can lift wholesale prices before the effect becomes visible in national economic data.

Crude has also moved higher. Brent briefly traded above $108 per barrel on Wednesday morning, September 16, a level last seen in July. If that rise persists, it could add further pressure to import costs. If it reverses, relief at Swiss petrol stations may still take time because distributors work through existing inventories and supply contracts.

Switzerland maintains compulsory fuel stocks for emergencies, and those reserves can support national supply during shortages. They do not, however, shield motorists from normal market price movements. The current increase reflects the cost of replacing and transporting commercial fuel, not a reported release of emergency stocks.
