The compenswiss fund, which manages Switzerland's social security assets, ended 2025 with total assets of CHF50.6 billion and a net return of 6.34%. However, the fund warns that the upcoming introduction of the 13th AHV pension will place a considerable strain on future finances.

"It will not be enough to cover expenditure in 2026."
"The 13th AHV pension... is putting a considerable strain on the fund."
Switzerlandâs social security war chest has swelled to a staggering CHF 50.6 billion ($65.65 billion), marking a decisive financial victory for 2025. Compenswiss, the federal body tasked with managing these critical funds, reported a robust net return of 6.34%. This is not just a marginal gain; it represents a significant leap from the CHF 46.1 billion recorded the previous year. The numbers paint a picture of a system currently flush with cash, defying global economic uncertainties to deliver a solid performance for the Swiss public.
However, while the headline figures are cause for celebration, a closer look reveals a cooling trend. The 6.34% return, while impressive, falls short of the blistering 7.33% achieved in 2024. This deceleration serves as a subtle reminder that double-digit growth is never guaranteed. Yet, for now, the AHV (old-age and survivorsâ insurance) and IV (disability insurance) funds have ended the year firmly in the black, providing a temporary buffer against the fiscal challenges on the horizon.
Gold glitters and equities rallyâthese were the twin engines powering the Swiss social security surplus in 2025. Compenswiss capitalized on favorable market conditions, riding the wave of rising stock prices and the enduring stability of precious metals. The fundâs strategic allocation allowed it to harvest significant gains from currency effects and global equity markets, proving once again that diversified investment is the bedrock of national financial security.
This performance underscores the fund's reliance on volatile market mechanics to subsidize social welfare. While 2025 delivered a windfall, the dependence on equities and gold exposes the system to market corrections. The "good result" cited in the press release was hard-won, but it stands in stark contrast to the operational reality: investment returns alone cannot sustain the system indefinitely. As the markets shift, so too does the security of these returns, making the fund's reliance on asset performance a high-stakes game for future pensioners.
The calm before the fiscal storm is ending. Despite the multi-billion franc surplus, compenswiss has issued a stark warning: the introduction of the 13th AHV pension is poised to place a "considerable strain" on the fund. Starting in December 2026, this new payout will drain liquidity at an unprecedented rate. The fund has already been forced to ring-fence CHF 2 billion in cash reserves specifically to meet this new obligationâmoney that is now sitting idle rather than generating returns in the market.
This is the critical pivot point for Swiss social security. The investment returns of 2025, no matter how robust, will not be enough to cover the exploding expenditure of 2026. The Federal Social Insurance Office is already projecting increasing distribution deficits. The mathematics are unforgiving: the outflow of cash for the 13th pension is a fixed liability, while market returns remain a variable gamble. We are witnessing the beginning of a structural shift where annual surpluses may soon be replaced by chronic liquidity battles.
While the accountants at compenswiss tally the assets, the politicians in Bern are grappling with the bill. The exact financing of the 13th AHV pension remains a contentious battlefield in Parliament. With the fund explicitly warning that current returns won't cover 2026 expenditures, the pressure is mounting to find a sustainable funding model immediately. The era of relying solely on market performance to patch over structural deficits is effectively over.
The implications for the Swiss taxpayer are clear and urgent. Whether through increased VAT, higher wage deductions, or other fiscal instruments, the gap must be filled. The 2025 surplus provides a psychological cushion, but it does not solve the arithmetic reality. As distribution deficits widen, the debate will shift from "how much do we have?" to "who is going to pay?" The 13th pension was a victory for voters, but the invoice is now sitting on the desk of the Federal Council, and the deadline is fast approaching.
