In an assessment by the comparison platform bonus.ch, Switzerland is poised to face a potential average increase of 4.5% to 5% in health insurance premiums by 2027. This anticipated rise comes despite insurers having bolstered their reserves, largely due to escalating healthcare costs that continue to exert pressure on premiums. The premiums saw a 4.4% increase in 2026, and further adjustments are expected. In a more optimistic scenario, increases might be capped at 3.5% to 4%, but unforeseen healthcare expenditures or costs related to new outpatient tariffs could drive the increase above 5%.
Individual insurance policyholders might experience varied premium hikes based on factors such as insurer, canton, premium region, age, deductible, and insurance model. Some could see their premiums rise by over 10%, with a potential spike up to 20% in certain cases. Although drastic changes in an insurer’s tariff structure could lead to even larger adjustments, such instances are not considered representative of the market at large by bonus.ch.
The ongoing rise in healthcare costs is a significant contributor to these predicted premium hikes. During the second quarter of 2026, costs associated with Switzerland’s mandatory health insurance system were 0.4% higher than the previous year, despite a 2.9% growth in the first quarter. The average annual cost per insured individual came to CHF 4,834, marking a CHF 21 increase from the year before. While recent figures might suggest a slowdown in spending, they do not fully account for delays in outpatient billing due to a newly introduced flat-rate tariff system. As outstanding invoices are processed, recorded costs could increase, obscuring any real reduction in healthcare spending.
Healthcare expenses show significant variability across Switzerland’s cantons. The second quarter of 2026 saw increases such as 9.6% in Schaffhausen, while Zug experienced an 8.7% decline. Other cantons like Glarus, Graubünden, Jura, and Zurich also reported above-average increases, contrasting with regions like Solothurn, Basel-Stadt, Bern, Thurgau, and Geneva, which reported lower costs compared to the previous year. Despite this, projections from the KOF Swiss Economic Institute indicate a continued rise in healthcare costs, with expectations of a 4.5% increase per insured person in 2026 and an additional 4% in 2027.
Swiss health insurers are dealing with heightened financial pressures, as estimates submitted to the Federal Office of Public Health suggest a more than 5% increase in healthcare costs for 2026. A potential catch-up effect could lead to premium adjustments exceeding the underlying cost hikes. Notably, while insurers have improved their financial standing with a combined surplus of nearly CHF 569 million in 2025, total reserves reaching approximately CHF 8.6 billion, these funds alone may not suffice to offset the consistent 4% to 5% annual growth in healthcare spending. The variability in reserve levels among insurers, as detailed by bonus.ch, underscores the ongoing debate about the balance between maintaining financial buffers and managing premium policies effectively.
