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 29 July 2026
At the end of June, mortgage rates and Swiss government bond yields stood at their lowest levels since early March. The trigger was the signing of a memorandum of understanding between the United States and Iran in mid-June. This raised hopes of a swift reopening of the Strait of Hormuz, pushing interest rates lower. However, those hopes faded in July. Reaching an agreement in the Middle East conflict is likely to remain challenging in the second half of the year. As a result, both oil prices and interest rates moved higher again.
In the coming months, interest rates are unlikely to follow a clear trend. Instead, they are expected to remain range bound.
One factor that could support lower interest rates is the prospect of a Middle East agreement. The prospects for a full reopening of the Strait of Hormuz in the coming months remain favorable, as US President Trump is likely to have little appetite for persistently high oil prices ahead of the midterm elections this fall. This would reduce inflationary pressures and pave the way for lower interest rates.
On the other hand, a recovery in the eurozone economy, followed by stronger growth in Switzerland, could support higher interest rates. If higher spending on defense and infrastructure provides fresh momentum to the German economy and, by extension, the broader European economy in the coming months, this is also likely to support higher bond yields and mortgage rates.
Overall, both factors suggest that government bond yields and mortgage rates are likely to remain within their current range for the time being. The same applies to SARON mortgages. Provided the economic recovery unfolds as expected, SARON rates are unlikely to rise again before next year.
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 | 28/07/26 | 31/12/26 | 30/06/27 | 31/12/27 | 30/06/28 |
|---|---|---|---|---|---|
SARON | -0.04 | 0.00 | 0.25 | 0.31 | 0.41 |
Swap 3Y | 0.27 | 0.22 | 0.40 | 0.48 | 0.58 |
Swap 5Y | 0.40 | 0.36 | 0.51 | 0.58 | 0.67 |
Swap 10Y | 0.66 | 0.73 | 0.72 | 0.76 | 0.84 |
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.
