Saron mortgage: interest adjustment every three months

    • Benefit from falls in interest rates
    • Market-oriented interest rate
    • Term: 3 years

  • Option to switch to a fixed-rate mortgage at the end of each quarter

  • The Saron mortgage is a money market mortgage based on the Swiss reference interest rate SARON® (Swiss Average Rate Overnight). The interest rate on the Saron mortgage is variable: if the SARON® falls, the mortgage interest rate falls; if the SARON® rises, the mortgage interest rate rises. Unlike a fixed-rate mortgage, the interest rate for this financing solution is not fixed in advance over the term, but is adjusted every three months.

    SARON® is calculated daily by SIX based on the interest rate at which Swiss banks lend each other money overnight. The Saron mortgage uses the Compounded SARON® so that interest can be charged “only” every three months instead of daily. This corresponds to the compounded individual SARON® daily rates (current interest rates and exchange rates at snb.ch) for the past three months. The compounded SARON® is generally close to the Swiss National Bank’s policy rate. 

    In addition to the Compounded SARON® money market reference interest rate, the Saron mortgage comes with an agreed, customer-specific margin. The margin remains unchanged over the entire term.

    Terms for interest rates

    All interest rates apply to first-class residential real estate and borrowers (best creditworthiness). Individual customer interest rates are set according to risk. This means the loan-to-value and financial burden ratios for individual customers have an impact on the amount of interest payable.

    • The Saron mortgage is the right choice for you if you are willing and able to take the risk of interest rate fluctuations. If the interest rate level is medium or high when you take out your mortgage, a Saron mortgage may well be worthwhile. 

    • The Saron mortgage is market-oriented. The interest rate is adjusted accordingly if the reference interest rate rises or falls. This can be both an advantage and a disadvantage for you as a customer.

      With PostFinance, you have the option of converting your Saron mortgage into a fixed-rate mortgage at the end of the quarter. This allows you to secure lower interest rates in the long term with a fixed-rate mortgage, meaning you can remain flexible throughout the Saron mortgage term.
