Qu'est-ce que le/la Hypothèque à taux fixe ?

Une hypothèque à taux fixe est un prêt immobilier dont le taux d'intérêt reste inchangé pendant toute la durée – typiquement 5, 10, 15 ou 25 ans – assurant des mensualités prévisibles.

Fixed rates trade certainty for cost: the borrower pays a premium over the variable rate (the term premium) to lock in payments. The longer the fix, the higher the premium, but the more insurance against rate volatility.

In Switzerland, 5-, 10- and 15-year fixed-rate mortgages dominate, often combined into a 'tranche' strategy spreading maturities to limit refinancing risk. US mortgages are heavily 30-year fixed — uniquely long because they are federally backed and prepayable without penalty.

Exemple

A borrower locks a CHF 800k mortgage at 2.5% fixed for 10 years; even if rates rise to 5%, monthly interest of about CHF 1,667 stays the same until the term ends.

Questions fréquentes

Is a fixed rate always better?+

Not always — if rates fall, you stay locked at the higher rate or pay a prepayment penalty to refinance.

What term should I choose?+

Match the term to how long you plan to keep the loan and your appetite for rate risk.

Can I break a fixed-rate mortgage?+

Yes — but expect to pay a prepayment penalty (Vorfälligkeitsentschädigung) that can be substantial.
