BERN. The posters have not yet gone up, but the money is already moving. Six weeks before the November referendum on pension reform, both camps have filed their committee disclosures with the Federal Audit Office, offering the first full picture of what a national vote campaign costs in 2026 and who pays for it.
The filings are the product of the transparency rules parliament adopted in 2022, which require campaign committees to disclose donors giving more than CHF 15,000 and to publish budgets once spending exceeds CHF 50,000. Before then, Swiss vote campaigns were largely a financial black box, a distinction Switzerland held almost alone among western democracies.
The committee for the reform, operating under the banner Secure Pensions, reports commitments of CHF 6.1 million. Its backers include the employers' federation, the insurers' association and the banking lobby, with the largest single disclosed donation, CHF 250,000, coming from an insurance industry group. The alliance against the reform, Fair Pensions, reports CHF 3.8 million, roughly 60 per cent of it from trade union funds.
The imbalance follows a familiar pattern, but the totals have grown. Campaign professionals say a competitive national vote now costs between CHF 5 million and CHF 8 million per side, driven by digital advertising, regional newspaper supplements and the rising price of poster sites in Zurich, Geneva and Lausanne. Two decades ago, a third of that was considered lavish.
What the money buys is not just visibility but organisation: call centres in the final fortnight, translation into the national languages, and the small army of stand operators outside railway stations. The pension vote, with its direct effect on every household's finances, is considered one of the few subjects that can still move voters without heavy spending, which both camps cite as they spend heavily.
Reaction from the parties has tracked the money. The centre right, which dominates the yes committee, calls the disclosures proof the system works. The left notes that corporate donors can deduct contributions as business expenses while union dues are not deductible, an asymmetry it intends to raise in the winter session.
The watchdogs are watching the gaps. Associations and foundations that fund campaigns need not reveal their own donors, a structure transparency advocates call the nesting doll problem. One foundation active in the yes campaign has disclosed CHF 400,000 in spending while naming no source, which is entirely legal under the current rules.
“Voters deserve to know who is paying for the arguments they read,” a spokesperson for a transparency watchdog said, adding that the group will publish weekly tallies of disclosed spending until polling day.
Defenders of the status quo argue that aggressive disclosure chills legitimate participation, pointing to small donors who fear exposure in a polarised climate. They note that Switzerland's system of frequent votes would collapse under American style compliance costs, and that political money, unlike political speech, has never decided a Swiss referendum on its own.
The committees must update their disclosures weekly until the vote on the last Sunday of November, and file final accounts by February. The Federal Audit Office will then publish a consolidated report, the first of its kind for a pension vote, which parliament's finance committees have already said they intend to debate.
The broader significance reaches past pensions. The 2022 rules were themselves a compromise, adopted to forestall a popular initiative demanding far stricter disclosure, and this campaign is their first serious stress test. How they perform will shape the debate on extending the rules to election campaigns, which remain largely unregulated at the federal level.
The ledgers published after the vote will set the benchmark for every campaign that follows. Whatever the November result, the committees being formed today know their donors will be read tomorrow, and that knowledge is quietly changing what gets given.
