Interest Rate Reversal in Switzerland: Why Mortgage Rates Are Falling Again

After a few weeks of slightly rising rates, long-term yields on the Swiss capital market are turning downward again. Accompanying them, mortgage rates are also easing. For anyone looking to renew financing soon or buy a home, a favorable window is opening once again. Below, we explain what's behind this movement, where the current rates stand, and what considerations borrowers should now take into account.

A Movement That Doesn't Seem to Fit at First Glance

Actually, there was much to suggest higher interest rates. Tensions in the Middle East and the temporary closure of the Strait of Hormuz pushed up energy prices and thus inflation expectations worldwide. At the same time, the European Central Bank has recently tightened its policy. In theory, this should have created upward pressure on yields in Switzerland as well.

In reality, the opposite is true. Yields on ten-year government bonds have recently moved back toward their spring levels, and short-term maturities are trading near zero. The ten-year swap rate, the most important reference for fixed-rate mortgages, stood at around 0.58 percent in mid-June. Luzerner Kantonalbank expects a largely unchanged level of around 0.60 percent over the next three months, and only a moderate increase toward 0.80 percent over a twelve-month horizon.

Why are interest rates falling in Switzerland despite contrary international signals? Valentino Guggia from Migros Bank points to domestic reasons. The robust economy, low inflation, and the traditional role of the Swiss franc as a safe haven more than offset a possible euro strength resulting from the larger interest rate differential with the eurozone. Swiss franc investments thus remain in demand, and demand for securities drives down yields.

The Anchor in the Background: The National Bank Remains at Zero

The true pace setter is monetary policy. The Swiss National Bank kept its key interest rate at 0.0 percent at its June 18, 2026 monetary policy assessment—the same level as since June 2025. Inflation had recently increased, from 0.1 percent in February to 0.6 percent in May, triggered mainly by more expensive petroleum products. Over the entire forecast horizon, however, inflation remains within the range of price stability. The National Bank expects an average of 0.6 percent for 2026 and 2027, and 0.7 percent for 2028.

What is noteworthy is the reasoning. Central banks usually look past a temporary energy price spike, as it slows the economy and can even dampen prices in the medium term. Fredy Hasenmaile, Chief Economist at Raiffeisen, also emphasizes that energy price effects are more subdued in Switzerland. Reasons for this are the internationally low share of energy spending in the consumer basket and the strong franc. The National Bank currently sees an excessive appreciation of the franc as a greater risk than a temporary rise in inflation and explicitly keeps open the option of intervening in the currency market.

Where Mortgage Rates Stand Today

For property owners, this is reflected in falling rates across nearly all maturities. The reference rate Saron is currently around minus 0.04 percent, CHF swap rates as the basis for fixed-rate mortgages are about 0.26 percent for five, 0.55 percent for ten, and 0.72 percent for fifteen years (as of 30.06.2026). The current daily mortgage rate comparison shows the low level clearly. As top rates, a five-year fixed mortgage is available at around 1.05 percent, a ten-year at about 1.29 percent, and a fifteen-year at around 1.60 percent. The three-year Saron mortgage starts at around 0.65 percent. Fixed-rate mortgages have recently eased across all maturities.

For comparison: at the peak of 2022 and 2023, ten-year fixed-rate mortgages temporarily traded near 3 percent. In a long-term comparison, today's conditions are therefore extremely attractive.

It remains important: The quoted figures are top conditions, that is, the cheapest rates available on the market. Your personal rate depends on loan-to-value, affordability, creditworthiness, property type and location, as well as the financing amount. An independent comparison of several providers is almost always worthwhile.

What's Next, and Should You Act Now?

Borrowers and future homeowners are faced with two questions. Where are interest rates headed, and should you take the opportunity to renew?

On direction, the market is largely in agreement. Money markets do not expect any further key rate moves in Switzerland this year. In a survey conducted by LSEG, 28 of 31 institutions expect a rate increase only from the second half of 2027 at the earliest. Only a few houses expect it sooner. Brian Mandt, Chief Economist at Luzerner Kantonalbank, considers the first quarter of 2027 possible, UBS names the second quarter, J. Safra Sarasin the end of 2027. Swiss Life assumes that the National Bank will keep the key rate at zero at least until the end of 2026, and then begin to raise it only slowly. Hypothekarbank Lenzburg also sees zero percent for all of 2026 as its base scenario, and considers the risk of a return to negative rates even more likely than an imminent rate increase.

For practical purposes, this means different things depending on your situation. If you have a Saron mortgage, you currently benefit the most. As long as the National Bank stays at zero, the variable element also remains stable, and a sudden spike in Saron is unlikely in the current environment. Those who value flexibility and have sufficient risk capacity often fare better than with a fixed-rate mortgage.

If you are seeking planning security, 2026 offers good conditions to lock in a multi-year fixed-rate mortgage at attractive rates. Since a slight medium-term increase in swap rates is expected for long maturities, securing today's level can be worthwhile. A forward mortgage allows you to lock in the current rate months before an existing arrangement expires, for a forward premium that is lower the shorter the lead time.

For many households, a mixed strategy is the sensible middle ground. Splitting into several tranches with different maturities, possibly combined with a Saron portion, spreads the interest rate change risk. One side note: several providers have recently become more selective when issuing new or renewing contracts. So you should plan a bit more time when choosing a provider.

Conclusion

The surprising downward movement in yields prolongs a pleasant period for homeowners. The key interest rate is likely to stay at zero for quite some time, genuine inflation risks are not in sight in Switzerland, and mortgage rates remain at historically low levels. Whether Saron, fixed-rate mortgage, or a combination, the best choice depends on your risk tolerance, need for planning, and personal situation. A current, independent comparison is the simplest way to benefit from the favorable environment.
