Do you have questions about mortgage interest rates? We can help. Here you’ll find everything you need to know about this topic.
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.
Status as per 18 June 2026
At the beginning of May, yields on Swiss government bonds and mortgage interest rates rose against the backdrop of the global rise in inflation. At the beginning of June, however, they decreased again, as hopes grew for a swift resolution to the Middle East conflict and a possible reopening of the Strait of Hormuz. Uncertainty about the further course of the Middle East conflict nevertheless remains and continues to shape the interest rate outlook.
This uncertainty also influenced the Swiss National Bank (SNB) monetary policy assessment of 18 June. At its quarterly meeting, the SNB decided to keep its key interest rate unchanged at 0%. The reasons for the continued expansionary monetary policy are the low level of inflation in Switzerland and a Swiss economy that is not expected to grow as much as it could this year.
The National Bank is likely to maintain its zero interest rate policy over the coming quarters. The uncertainty stemming from the Middle East conflict does not bode well for an immediate acceleration in the Swiss economy. However, recovery could begin in 2027 if the German fiscal stimulus takes effect and stronger momentum in the Eurozone also boosts Swiss exports. An improved economic environment would then likely prompt the SNB to normalize its current expansionary monetary policy and begin raising the key interest rate from mid-2027 onward.
However, such a move is unlikely to have much impact on current interest rates. First, it is still subject to a great deal of uncertainty, and second, the markets are already anticipating an SNB rate hike. Accordingly, both government bond yields and mortgage interest rates are likely to remain at a low level for the time being. This is expected to apply to SARON mortgages as well, although an increase in interest rates next year appears possible.
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:
Rates | 30/06/26 | 31/12/26 | 30/06/27 | 31/12/27 |
|---|---|---|---|---|
SARON | -0.04 | 0.00 | 0.25 | 0.31 |
Swap 3Y | 0.22 | 0.25 | 0.39 | 0.47 |
Swap 5Y | 0.34 | 0.37 | 0.50 | 0.57 |
Swap 10Y | 0.64 | 0.72 | 0.71 | 0.75 |
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.
Since mid-2024, inflation has remained 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.
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.

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.
Interest rate level | Fixed-Rate Mortgage short | Fixed-Rate Mortgage medium | Fixed-Rate Mortgage long | SARON Mortgages |
|---|---|---|---|---|
High | suitable under certain conditions | not suitable | not suitable | suitable |
Decreasing | suitable under certain conditions | not suitable | not suitable | suitable |
Normal | suitable | suitable | suitable | suitable |
Rising | suitable under certain conditions | suitable | suitable | suitable under certain conditions |
Low | suitable under certain conditions | suitable | suitable | suitable |
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.
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.
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.
