Health insurance premiums are now the leading source of concern for Swiss households. Between cantons where residents pay twice as much as their neighbours, the recurring debate over a single public insurer and the persistent question of how to make policyholders more accountable, the system is searching for an answer that neither politics nor the market has yet been able to provide.

In 2026, the average monthly premium in Switzerland stands at 393 francs for basic insurance, up 4.4% from the previous year, which had already seen much steeper increases. But this national average masks sharply different realities depending on where people live. In Geneva, the most expensive canton in the country, an adult pays an average of 586 francs per month, while a resident of Appenzell Innerrhoden pays only 271 francs — more than double for strictly identical coverage. The finding is stark, but it is not arbitrary. These gaps closely mirror the actual cost of healthcare in each region, and that is precisely where the full complexity of the problem lies. According to a study by the CSS Institute, 60% of the differences between cantons are explained by healthcare demand, in other words by policyholders’ own behaviour, and 40% by the density of medical provision. In urban cantons such as Geneva, Basel-Stadt or Ticino, the concentration of doctors, specialists and hospitals mechanically stimulates the consumption of care. Supply creates its own demand, and premiums follow. Added to this is a cultural factor that is often underestimated: French-speaking and Ticino policyholders consult doctors more often on average than their German-speaking counterparts, whose tradition of individual responsibility in health remains a deeply rooted marker.

It is precisely this observation that periodically revives the debate over a single public insurer. Its supporters argue that the current system sustains a largely fictitious form of competition: insurers do not compete on the quality of care, which is set by the LAMal, but on selecting low-risk customers and on high administrative costs. A single public insurer, they say, would make it possible to pool these expenses and introduce greater transparency in premium setting. Opponents counter that a monopoly would kill innovation and efficiency incentives, and turn health insurance into an uncontrollable bureaucratic machine. The Swiss electorate, consulted four times between 1994 and 2014, rejected the idea each time, most recently by 61.5% of the vote. The verdict at the ballot box is clear, even if pressure on household budgets weakens it with every new premium increase. Since the LAMal came into force in 1996, premiums have risen structurally faster than households’ purchasing power, turning health insurance into a genuine regressive tax for the middle classes.

That leaves accountability as the remaining path — more consensual in principle, more delicate in practice. The deductible lever already exists: an insured person who chooses the maximum deductible of 2,500 francs instead of the minimum 300 francs reduces their monthly premium significantly, but takes on greater costs if illness strikes. This mechanism works for healthy people; it penalises people with chronic illnesses, for whom a high deductible quickly becomes a financial trap. Beyond deductibles, what is missing is genuine health education. Too many policyholders still do not know that calling a family doctor before going to A&E can avoid substantial costs that are then passed on to all premiums. Too few know that alternative models — group practice, HMO, telemedicine — offer discounts of 10% to 20% without reducing the quality of care. Researcher Caroline Chuard-Keller points to a revealing paradox: most insured people do not know how their premiums are calculated, nor why they vary so much depending on where they live. That is perhaps where everything begins, in this space between ignorance and decision, an area that neither insurers nor public authorities have truly invested in yet. Stabilising healthcare costs will require less a break with the system than the accumulation of coherent reforms: regulating supply, making policyholders more accountable, guaranteeing transparency and preserving solidarity. A modest programme in its stated ambitions, demanding in its implementation, very much in keeping with Switzerland itself.
