Switzerland’s health insurance premiums are anticipated to rise significantly by 2027, with projections suggesting an increase of 4.5% to 5%, as evaluated by the comparison platform bonus.ch. Despite insurance companies bolstering their reserves, the escalating costs of healthcare are predicted to exert ongoing pressure on premium rates. Last year, premiums saw an average uptick of 4.4%, and another considerable adjustment is expected in the coming year. In an optimistic scenario, the increase might be contained to 3.5% to 4%, but unforeseen spikes in healthcare spending or costs associated with transitioning to new outpatient tariffs could drive the increase beyond 5%. Individual policyholders might experience varied premium hikes based on factors such as their insurer, location, age, deductible, and insurance model, with some facing increases of 10% or even up to 20% in certain instances.
The persistent rise in healthcare costs under Switzerland’s mandatory health insurance system remains a critical driver of these projected premium hikes. In the second quarter of 2026, the costs covered by mandatory health insurance were 0.4% higher than in the previous year, following a 2.9% increase in the first quarter. However, these figures might not fully capture the actual expenditure due to delays in outpatient billing prompted by a new flat-rate tariff system. While outpatient costs recorded a decline, there could be an upward revision as pending invoices are processed. Meanwhile, other healthcare categories like home care services, psychological services, and physiotherapy have seen substantial cost growth, further complicating interpretations of the recent spending slowdown.
Variations in healthcare spending are evident across Switzerland’s cantons. For instance, Schaffhausen experienced a 9.6% increase, contrasting with an 8.7% decline in Zug. Other regions such as Glarus, Graubünden, Jura, and Zurich reported above-average increases, whereas cantons like Solothurn, Basel-Stadt, Bern, Thurgau, and Geneva saw lower costs than the previous year. Despite these regional disparities, forecasts by the KOF Swiss Economic Institute at ETH Zurich predict an overall increase in healthcare costs per insured person by 4.5% in 2026 and an additional 4% in 2027, potentially escalating average per-person costs to nearly CHF 5,400 by 2027.
Insurers are also grappling with additional financial pressures. Reports submitted to the Federal Office of Public Health suggest that healthcare costs could rise by over 5% in 2026. The FOPH has indicated a potential catch-up effect when calculating premiums for 2027, as the estimated combined ratio for 2026 nears 101%, implying that collected premiums might not entirely cover expenses. Consequently, premium adjustments could exceed the underlying rise in healthcare costs. Nevertheless, Swiss health insurers have improved their financial standing, recording a combined surplus of CHF 569 million in 2025, which was allocated to reserves, now amounting to approximately CHF 8.6 billion.
These reserves provide a financial cushion against unforeseen developments, but disparities among individual insurers’ reserve levels remain. For instance, reserve rates span from 53% for Visana to 5% for Philos. Some insurers have seen significant declines in reserve ratios since 2020, with CSS and Helsana experiencing notable reductions. The ongoing debate regarding reserves highlights the balance insurers must maintain between reducing premiums in the short term and sustaining a sufficient financial buffer to absorb unexpected cost increases without abrupt premium changes.
