In brief: what the latest SNB decision from 19.03.2026 means

Status as at: 19.03.2026
Editorial deadline: 19.03.2026

  • The Swiss National Bank (SNB) is maintaining its zero interest rate. There are no signs of a more restrictive path, given the difficult economic environment.
  • Saron mortgages continue to provide inexpensive financing in this environment.
  • Fixed-rate mortgages also offer attractive conditions due to low capital market interest rates.

Current economic situation in Switzerland

After a significant setback in the third quarter of 2025, the Swiss economy grew slightly again by 0.2 percent towards the end of the year. However, the economic environment remains challenging. The export sector continues to be hit by US trade tariffs and weak demand from major trading partners such as Germany. Although export volumes have now levelled off, they are lower than the average for 2024 or at the start of 2025. The recent significant appreciation of the Swiss franc, which is making Swiss goods more expensive on the international market, is exacerbating the situation.

In addition, weak sales are gradually having an impact on the labour market. The unemployment rate rose significantly towards the end of last year. This means there is a risk that the weakness in the export sector will spread and may increasingly spill over into the domestic economy . The significant slump in retail sales in January 2026 may not yet indicate sustained weakness in consumption, but it is an initial warning sign.

However, in its monetary policy assessment of 19 March 2026, the Swiss National Bank (SNB) decided to leave the policy rate  at zero percent. Besides the aim to avoid negative interest rates, this is likely also due to the fact that no action was required on the inflation front . Switzerland is one of the few western currency areas where price stability  prevails in the long term. The inflation rate has barely changed over recent months and currently stands at 0.1 percent. While there is still a danger of slipping into negative territory – and, in turn, outside the SNB’s target range – this risk has not increased.

Key for table 〉 ­­

The pressure on the Swiss National Bank’s (SNB) interest rate decisions tends to be downwards. However, the fact that it has not eased monetary policy again despite the worsening economic environment shows that it wants to avoid negative interest rates if possible. This means the policy rate environment looks set to remain stable for the time being. This expectation of a continued low interest rate policy is also reflected in Swiss capital market interest rates , which are at a low level. In light of this, no major fluctuations are expected for medium and long-term mortgages.

Just over three years ago, mortgage interest rates in Switzerland were still well above the current level and briefly exceeded the 3 percent mark. This was triggered by the more restrictive monetary policy pursued by the Swiss National Bank (SNB), which raised its policy rate  to 1.75 percent in the wake of high inflation  after the coronavirus pandemic. Inflation has now eased significantly. This means monetary policy has returned to a low interest rate environment. It has led to significantly lower mortgage interest rates, even though they have not fallen to the same extent since the end of 2024, despite further policy rate cuts. As we don’t currently expect any change in monetary policy, we anticipate that mortgage rates in Switzerland will generally move sideways over the coming 12 months. We also expect stable performance for the 3-month Saron. Accordingly, the SNB is likely to leave its policy rate unchanged in the next monetary policy assessment on 18 June 2026.

In percent

The graphic shows the interest performance for 5- and 10-year fixed-rate mortgages and the 3-month Saron since the 2008 financial crisis. After a long phase of expansive monetary policy and falling interest rates, the interest rate level increased considerably in 2022 and at the beginning of 2023. However, following the easing of monetary policy last year, interest rates for fixed-rate mortgages have again fallen significantly.

Single-family homes and condominiums

Prices for owner-occupied apartments rose sharply in the past quarter. By contrast, single-family home prices have barely changed compared with the previous quarter, after previously having recorded significantly higher growth rates. This may indicate that single-family homes have now reached such a high price level that owner-occupied apartments are considered a more affordable alternative for many buyers. Looking back over 2025 as a whole, residential property prices remain strong. Both owner-occupied apartments and single-family homes may have  benefited from the generally low capital market interest rates . As in the previous two quarters, the price trend for rental apartments was again only slightly positive. The fall in the reference interest rate  in September, which took effect in December, is likely to gradually have an impact on this.

The graphic shows the price trend for single-family homes, rental properties and apartments. After prices for owner-occupied properties and, in particular, single-family homes rose sharply during the COVID-19 crisis, there were signs of normalization. Since the end of 2021, however, we are again seeing a trend of rising prices.

  • Forecasting is a well-founded assessment, not a certainty. Whether now is the right time for you very much depends on your personal risk appetite, your financial situation and your individual needs.​

    If interest rates are falling: if you expect interest rates to continue to fall, a Saron mortgage may be an attractive option to benefit from the cuts, depending on the interest rate level.​

    If interest rates are rising: if you are expecting an interest rate rise or budget security is very important for you, it may be a good idea to fix the conditions over the long term with a fixed-rate mortgage.

    Our specialists will be happy to help you find the right strategy.

  • The SNB policy rate can affect mortgage interest rates. This usually happens quickly with variable models such as the Saron mortgage, as these are based directly on short-term money market rates. Fixed-rate mortgages, however, are driven more by long-term capital market interest rates (swap rates) which to some extent already take into account anticipated future monetary policy and inflation. If a policy rate change is expected by the markets, its effect on fixed-rate mortgages could in many cases already be reflected in the interest rates beforehand.

  • Choosing the term is a strategic decision. Long terms (7–10 years or more) provide you with interest rate security over a long period of time, but are often slightly more expensive. Shorter terms (2–5 years) are usually cheaper, but require you to address the interest rate situation again sooner. Splitting is a popular strategy: you can split your mortgage into several tranches with different terms if required. This spreads the interest rate risk and avoids having to renew the total amount at once at potentially unfavourable conditions.

  • We expect Saron mortgages to remain broadly stable over the coming months.

  • Our interest rate forecasts are produced by our economists on the basis of in-depth analyses of the global and national economic situation, inflation trends and the monetary policy of central banks. They represent a likely development. However, ongoing or unforeseen economic or political events can have an impact on interest rate developments at any time. Forecasts should therefore always be seen as a guide and not a guarantee.

  • Prices are mainly influenced by supply and demand. Low mortgage interest rates can generally boost demand for home ownership, as financing costs fall. This can lead to stable or rising real estate prices. Conversely, if interest rates rise sharply, this can dampen demand – but it doesn’t have to, especially if supply remains tight. Political decisions on mortgage lending can also influence demand for residential property and therefore property prices.

  • Yes, that is possible. With a forward mortgage, you can secure the current interest rates today – even if your existing mortgage is not set to expire for several months (e.g. in six, 12 or up to 18 months). Depending on the lead time, requested term and market situation, an interest rate premium (forward premium) may be incurred. In return you will be protected against any interest rate rises until your current mortgage expires. Please contact us for a non-binding quotation.
