Swiss health insurance premiums are projected to rise by an average of 4.5% to 5% in 2027, according to analysis from the comparison platform bonus.ch, driven by escalating healthcare costs. This follows a 4.4% increase in 2026, with expectations for another significant adjustment in the coming year. In a more optimistic scenario, the rise could be confined to 3.5% to 4%, but unforeseen healthcare expenses or costs from transitioning to new outpatient tariffs might push the increase beyond 5%. Individual policyholders might face varied increases based on factors such as their insurer, location, age, and insurance model, with some premiums potentially rising by more than 10% and up to 20% in certain situations. While extreme tariff changes by insurers could lead to larger adjustments, such scenarios are not seen as representative of the market’s overall trend.
The continued rise in healthcare costs is a significant factor behind the expected premium hikes, with Switzerland’s mandatory health insurance system covering these increasing expenses. In 2026, mandatory insurance costs were recorded at 0.4% higher in the second quarter compared to the previous year, following a 2.9% increase in the first quarter. Average annual costs per insured person reached CHF 4,834, up by CHF 21 from the previous year. However, due to delays in outpatient billing under a new flat-rate tariff system, recorded costs in that sector have temporarily decreased. Once outstanding invoices are processed, the figures could show an increase, complicating the interpretation of the current slowdown in spending as a sustained trend. Categories such as home care services, psychological services, and physiotherapy continue to see notable growth, contributing to the overall cost pressure.
Healthcare spending patterns vary significantly across Switzerland’s cantons. In the second quarter of 2026, Schaffhausen saw a 9.6% increase, while Zug experienced an 8.7% decrease. Other cantons like Glarus, Graubünden, Jura, and Zurich reported above-average increases, whereas Solothurn, Basel-Stadt, Bern, Thurgau, and Geneva saw lower costs than the previous year. Forecasts from the KOF Swiss Economic Institute predict a 4.5% increase in healthcare costs per insured person in 2026, followed by a further 4% rise in 2027. This growth would push average costs from CHF 4,968 per person in 2025 to nearly CHF 5,400 in 2027, marking an increase of approximately CHF 900 per person over the 2023–2027 period.
Despite the pressure from rising costs, Swiss health insurers have bolstered their financial standing, reporting a combined surplus of nearly CHF 569 million in 2025, which has been added to reserves now totaling around CHF 8.6 billion. These reserves offer a buffer against unexpected developments, yet bonus.ch highlights they cannot indefinitely offset healthcare spending growing at a 4% to 5% annual rate. However, reserve levels vary significantly among insurers, with Visana holding a 53% reserve rate, Agrisano at 39%, and Philos at 5% as of 2024. Since 2020, several insurers have seen their reserve ratios decline, linking the debate over reserves closely to premium policy. Maintaining adequate reserves can help insurers handle unexpected cost increases without sharp premium adjustments, while lower reserves might offer short-term premium relief.
