Asian Tourist Drop Slows Swiss Summer Tourism Growth.

Switzerland’s summer tourism sector is expected to slow down in 2026, mainly due to a sharp decline in visitors from Asia. According to the latest forecast from the KOF Swiss Economic Institute at ETH Zurich, overnight hotel stays are projected to fall by 1.6% to around 24.8 million.

Researchers highlight that the ongoing Iran conflict is having a significant impact on global travel patterns, particularly long-haul flights. Rising fuel costs, higher airfares, and longer or less secure flight routes are discouraging many international tourists from travelling to Switzerland this summer.

The study shows that foreign guest overnight stays are expected to decline by 2.9% to 13 million. The biggest drop is predicted in visitors from Asia, which could fall by around 10% to 1.5 million overnight stays. Chinese tourists are expected to see an even sharper decline of approximately 25.7%, reducing their total to 0.4 million.

Asian visitors play an important role in Switzerland’s tourism economy, especially in major cities where long-distance tourism supports hotels, retail, and guided services. Their share of foreign overnight stays is expected to drop from 12.4% in summer 2025 to about 11.5% this year.

While international tourism is weakening, domestic demand is showing slight growth. Swiss residents are expected to generate around 11.8 million overnight stays, marking a modest increase of 0.2%. European visitors are also expected to remain relatively stable at 6.7 million overnight stays, a slight decrease of 0.4%.

Experts explain that European travellers are less affected because they can still reach Switzerland easily by car, train, or short-haul flights. In contrast, long-distance travel markets are more sensitive to fuel prices and geopolitical uncertainty.

Looking ahead, the winter season 2026/27 is expected to remain stable, with around 18.7 million overnight stays forecast. Unlike the summer season, winter tourism relies more on regional visitors and Swiss residents, making it less vulnerable to global disruptions.

The KOF also noted that the previous winter season was strong overall, although momentum slowed towards the end due to weaker snow conditions and early effects of global conflict.
