Summary: The Bilateral Agreements III entail estimated costs of approximately CHF 1.4 billion annually for the federal budget -- consisting of the cohesion contribution (~CHF 350 million), EU programme participation (~CHF 950 million) and regulatory costs. Critics consider these costs too high; supporters point to the estimated per-capita benefit of CHF 5,200 annually until 2045.
According to economiesuisse, the annual costs amount to approximately CHF 1.4 billion [7]:
| Cost item | Amount (approx.) | Description |
|---|---|---|
| EU programme participation | ~CHF 950 million/year | Horizon Europe, Erasmus+, Digital Europe and others |
| Cohesion contribution | ~CHF 350 million/year | Regular contribution to EU cohesion fund |
| Total direct costs | ~CHF 1.4 billion/year |
Note: economiesuisse is the Swiss business federation and supports the Bilateral Agreements III. The figures cited come from their analysis of the negotiation result [7].
In addition to direct payments, indirect costs arise [1]:
The external regulatory impact assessment (RIA) by Ecoplan (May 2025) quantifies the costs of the partial adoption of the Union Citizens' Directive in detail [11]:
| Area | Additional Cases | Additional Costs/Lost Revenue |
|---|---|---|
| Social welfare | 3,000-4,000 persons/year | CHF 56-74 million/year |
| Supplementary benefits (EL) | ~500 persons | ~CHF 7 million/year |
| Tuition fees (universities) | -- | ~CHF 22 million/year |
| Public employment services | 3,700-8,800 job-seekers | CHF 9-22 million/year |
The additional social welfare costs arise because, under the UBRL, certain groups of persons are exempted from migration-law consequences when claiming social assistance. These persons incur "full costs" as they have no reckonable income -- unlike employed working poor who receive only partial support [11].
A key element of the UBRL is the right of permanent residence: after five years of uninterrupted, lawful residence with employment, EU/EFTA nationals receive an unlimited right of residence that is no longer linked to continued employment [11].
According to Ecoplan estimates:
The KGL Lucerne warns this means "potentially higher social costs and a certain loss of control over migration" [12].
Supporters emphasise that freedom of movement continues to apply only to employed persons or self-sufficient individuals, and persons without work or sufficient means have no right of residence [5].
Critics argue [1]:
The implementation of EU law burdens not only the federal government but also the cantons and municipalities, which are responsible for enforcement. Four cantons expressed reservations about the package in the consultation [5].
economiesuisse argues on the basis of a study by BAK Economics that the economic benefits of the Bilateral Agreements III far exceed the costs [7]:
| Indicator | Value |
|---|---|
| Per-capita benefit (until 2045) | ~CHF 5,200/year |
| Cumulative benefit (until 2045) | ~CHF 45,700 per capita |
| MRA trade volume (2023) | >CHF 96 billion (72% of industrial exports to the EU) |
| Electricity system savings | up to CHF 1 billion/year |
Note: The BAK study was commissioned by economiesuisse. The figures should be read in the context of this commission.
Supporters point to the costs of non-renewal: the erosion of existing agreements is already costing approximately CHF 1.3 billion annually according to Avenir Suisse (-> Erosion of the Agreements) [7].
The CHF 950 million for EU programme participation is not a sunk cost but an investment: Swiss researchers and companies receive in return access to funding and networks that yield returns many times the contributions [5].
