Why did Swiss mortgage rates rise if the SNB stays at 0%?

Retail mortgage quotes reflect market funding and bank margins, not just policy. Late in Q4, swap and mortgage-bond rates firmed, and lenders widened spreads to protect earnings and capital. Those shifts lifted all-in borrowing costs even with the SNB zero interest rate. Fixed offers moved first, while floating deals depend on each bank’s margin and product terms.

Should I choose an 8–9 year fix or a SARON-linked loan?

Pick the term that matches your plans and risk tolerance. Long fixes offer payment certainty if spreads stay wide. SARON-linked loans keep flexibility if funding costs fall. Compare total cost, not only the headline rate. Request multiple quotes, check break fees, and review amortization. Many households split exposure across both to balance certainty and optionality.

How do Switzerland housing prices affect affordability now?

With the median home near CHF 1.0 million, higher quotes increase monthly payments and equity needs. That tightens affordability for first-time buyers. Stress tests, taxes, and maintenance also matter. Focus on total ownership cost, not only the initial rate. If funding costs ease, the pressure could fade, but current margins may keep payments elevated in the near term.

What could push Swiss mortgage rates lower in 2025?

A decline in swap curves or mortgage-bond spreads would help. Stronger competition or improved bank funding could trim margins as well. SNB guidance matters, but market funding and retail pricing tactics often move first. Watch spring campaign offers, term premia across maturities, and any shift in discounting for energy-efficient homes or low loan-to-value deals.
