Mortgage interest rates: interest rate forecast and trend

Do you have questions about mortgage interest rates? We can help. Here you’ll find everything you need to know about this topic.

The current interest rate environment

We are currently in a context of slightly expansionary monetary policy with a key interest rate of 0.25%. The period from 2008 to 2022 was shaped by falling and sometimes even negative key interest rates, while the key interest rate rose as high as 1.75 percent in 2023.

The trend reversal towards higher interest rates began in 2022 when inflation rose following the coronavirus pandemic and due to the Russian attack on Ukraine. In order to curb inflation, the Swiss National Bank (SNB) raised the key interest rate five times until it reached 1.75 percent in June 2023. In 2023, inflation fell to below 2 percent, which corresponds to the price stability range defined by the SNB. This enabled the SNB to lower the key interest rate five times, bringing it down to its current level of 0.25%.  

The key interest rate is the interest rate through which central banks influence the behavior of commercial banks. After all, banks also have to keep borrowing money. The level of the key interest rate therefore has a significant impact on the level of mortgage interest rates.

Interest rate forecast: newest SNB interest rate cut expected to be the last

Status as per 20 March 2025

Yields on Swiss government bonds and mortgage interest rates rose sharply at the beginning of March following the new German government’s announcement of a major fiscal package for the next ten years and a significant easing of the debt brake. This led to a sharp rise in German yields, which also pushed up Swiss interest rates.

Fiscal support could slightly improve the economic outlook in Europe, which would also justify higher interest rates in Switzerland. However, we find the sharp increase in interest rates at the beginning of March exaggerated. This is especially the case in Switzerland, where future government debt has not increased, in contrast to Germany, and the risk premium on government bonds therefore remains low.

The Swiss National Bank’s (SNB) monetary policy assessment almost went unnoticed. The SNB has lowered its key interest rates again due to low inflation in Switzerland and the economic risks in the eurozone. Given the low interest rate level of 0.25%, this is likely to be the SNB’s last interest rate cut in this cycle.

Yields on Swiss government bonds and mortgage interest rates will probably settle at a lower level than today, but will not return to the lows seen last December. Mortgage interest rates linked to SARON are likely to remain at the current level.

    Long-term interest rates in percent

    Interest rates fluctuate repeatedly over the course of time. This can be due to a variety of factors. The last interest rate cycle began in 2022 and was marked by the following events:

    • In response to strong inflation following the pandemic and due to Russia’s war in Ukraine, the SNB – like other central banks – began raising its key interest rate in 2022. This led to a sharp rise in the yields of bonds.
    • To curb higher levels of inflation, the SNB continued to raise key interest rates in 2023, while bond yields remained high. In the course of 2023, inflation eased significantly. Yields began to fall sharply at the end of 2023 as the markets anticipated future rate cuts.
    • Last year and in the first quarter of this year, the SNB significantly reduced its key interest rates to 0.25% due to low inflation. We do not anticipate any further reduction in key interest rates.

    How the mortgage interest rate affects your mortgage

    The mortgage interest rate is one of the key factors when deciding on a mortgage. It affects the monthly payments as well as the total cost of your mortgage.

    Inflation reached over 3 percent at the end of 2022 and in early 2023. Interest rates also rose at the same time, leading to higher mortgage rates. As a rule, the higher the interest rate on bonds, the higher the mortgage interest.

    Inflation has now fallen below 1%. This has allowed the SNB to significantly reduce the key interest rate, which is also reflected in much lower mortgage interest rates  – both at the short end and at the long end of the interest curve.

    These economic factors affect mortgage interest rates

    Mortgage interest rates in Switzerland depend on a variety of factors. We provide you with an overview.

    Despite basic knowledge of these factors, it is advisable to rely on well-founded analyses by financial institutions.

    How interest rates affect your mortgage model

    When choosing the right mortgage strategy, there are numerous factors to consider.

    The most important aspects include:

    The current interest rate situation determines the starting position and the amount of mortgage interest when you take out a fixed-rate mortgage. With a SARON mortgage, on the other hand, you finance your home with a market-oriented interest rate that varies as interest rates change.

    Interest rate forecasts help when creating scenarios showing how high your future payments will be. The table below provides an initial idea of which type of mortgage could be suitable for you at current interest rates.

    Your personal mortgage profile describes your risk capacity and your risk tolerance. If, for example, you attach great importance to security and a fixed budget, your mortgage profile will be completely different from that of a person who actively follows interest rate developments and has financial reserves. You will probably sleep better with a fixed-rate mortgage because you will know exactly how much interest you will pay for a specific period of time.

    Individual influences for borrowers

    Factors such as the type of loan and the term of a mortgage can be chosen individually. This will of course affect the amount of mortgage interest, depending on the size and type of mortgage. This also depends heavily on the creditworthiness of the mortgage borrower and the value and location of the property.

    The better you understand your own financial possibilities, the higher your chances of getting the best-possible mortgage interest rate.

    The creditworthiness is based on the financial situation of the potential borrower. Before buying a house, the question arises as to how much equity you can contribute – as a rule, at least 20 percent of the property value is required.

    The ratio between equity and mortgage is called loan-to-value. If you contribute more equity, this can have a positive impact on the interest rate. The better you understand your own financial possibilities, the higher your chances of getting the best-possible mortgage interest rate.
