The current interest rate environment

The key interest rate set by the Swiss National Bank (SNB) currently stands at 0%. Following the series of interest rate cuts started by the SNB in 2024 and completed in mid-2025, the key interest rate has since remained stable. This is primarily due to the significant decline in inflation, which has been back in the price stability range since mid-2023 – i.e. between 0% and 2%.

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: low interest rate environment set to continue in 2026

Status as per 11 December 2025

Yields on Swiss government bonds and interest rates on fixed-rate mortgages rose slightly since mid-November. The trade deal between Switzerland and the USA reduces the tariff on Swiss exports to the USA from 39% to 15%. This will likely limit the risk of a significant economic slowdown and hence the likelihood of the introduction of negative key interest rates by the Swiss National Bank.

In its assessment at the beginning of December, the SNB left the key interest rate unchanged at 0%. We assume that it will continue on this course in 2026. Inflation is likely to remain low at 0.3% in the coming year. However, this is not enough to provoke discussions about deflation. We anticipate economic growth of 0.9% in Switzerland in 2026, which is well below the long-term average. However, a customs agreement will likely significantly reduce the downside risks. This speaks against further interest rate cuts.

But even interest rate hikes are still a long way off in this environment. Nevertheless, if the eurozone recovers thanks to the extensive German fiscal package, and if the economic outlook for Switzerland brightens at the same time, yields on government bonds and mortgage interest rates could rise slightly next year.

As long as the SNB leaves the key interest rate at 0%, the general interest rate level is likely to remain low in the long term. SARON-based mortgages are expected to move sideways.

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.
  • In 2024 and in the first half of 2025, the SNB gradually lowered its key interest rates to 0% in light of low inflation, which was coupled with a further decline in bond yields.

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.

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.
Your UBS mortgage team

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.

Tips for mortgage borrowers

We now know that mortgage interest rates are influenced by various factors. The question arises as to how best to keep an eye on developments in order to react in time. Here are some tips.
