Swiss mortgage rates June 2026: SNB, inflation and Swiss refinancing
On 18 June 2026, the Swiss National Bank maintained its policy rate at 0%, for the fourth consecutive time. The decision was widely expected, but it closes several weeks of speculation about a possible first tightening. With easing in the Middle East, the threat of a surge in inflation recedes, and the SNB confirms it will not touch its floor this year. For Swiss property owners, this stability in the policy rate should not obscure the essential point: long-term rates are not decided in Berne, and the SNB has specifically raised its inflation forecasts for the next three years.
18 June: status quo prevails
The SNB maintained its policy rate at 0.0%, opting for the fourth consecutive time for monetary stability. The decision confirmed the consensus of economists, who unanimously anticipated this hold. In Switzerland, consumer prices remain at a very low level: inflation stood at 0.6% year-on-year in May, clearly within the 0% to 2% target range set by the central bank.
The element that shifted the debate of recent weeks is the easing in the Middle East. The prospect of an agreement between Washington and Tehran has reduced the risk of a sustained energy shock, and with it the pressure that could have pushed the SNB to raise its rates preemptively. The franc has also eased somewhat in recent weeks, reducing the need to intervene. The institute headed by Martin Schlegel nevertheless reaffirmed that it remains ready to act in the foreign exchange market to prevent excessive appreciation of the currency, which would threaten price stability.
Six months ago, the debate was about a possible return to negative rates. In spring, it had shifted to the timeline for a first increase. The 18 June decision settles in favour of continuity, but it does not close the inflation question.
SNB raises inflation forecasts
The most instructive point of the communiqué is not in the rate decision, but in the revision of projections. The SNB has raised its inflation forecasts, a sign that price pressures have not disappeared, they have simply shifted in time. The expected price increase for 2026 and 2027 has been raised to 0.6%, versus 0.5% previously anticipated, and the projection for 2028 rises to 0.7%. Energy prices continue to push the index upwards, in an international context that remains fragile despite recent easing.
This nuance is decisive for anyone financing real estate. A central bank that keeps its rate at zero while raising inflation forecasts sends a clear signal: it judges inflationary pressures still moderate in the short term, but does not consider them extinguished. For long-term mortgage rates, which anticipate inflation over ten or fifteen years, it is this underlying trajectory that matters, more than the current level of the policy rate.
What the decision changes for mortgage rates
Two mechanisms separated by the 18 June meeting must be distinguished.
The SARON mortgage follows the SNB's policy rate directly. As long as it remains at zero, it remains unbeatable in current cost, and yesterday's decision extends this advantage for the coming quarters. This is good news for borrowers already on SARON. But this advantage is only guaranteed in three-month tranches, until the next decision. SARON remains relevant for profiles able to absorb volatility, without offering any long-term protection.
Long-term fixed rates obey different logic. They form on international capital markets, based on bond yields, not on SNB communications. Holding the policy rate does not mechanically drive them down. After the rise in December 2025, when indicative 10-year rates rose from 1.74% to around 1.91% under the dual effect of capital markets and widening bank margins, fixed rates remain above their 2025 lows. The SNB's upward revision of inflation forecasts does not argue for near-term easing of these long rates.
Our view: asymmetry remains intact
The 18 June decision does not change the risk structure, it confirms it. On the downside, potential remains virtually nil: the policy rate is at zero and the SNB has clearly signalled its reluctance to return to negative territory. Yesterday's status quo locks this floor in for the year. On the upside for long rates, catalysts have not disappeared: energy inflation still present, inflation forecasts revised upward through 2028, and a geopolitical context eased but not stabilised. When risk on long rates tilts to one side, the rational strategy is to hedge against this risk while the cost of hedging remains low.
And that is still the case. Long-term fixed rates trade between 1.6% and 1.9% depending on the institution, levels that remain historically low. The gap between indicative rate and negotiated rate remains considerable: on the market, the difference between an indicative rate close to 1.9% and a negotiated rate around 1.25% represents several thousand francs in annual savings on a medium-sized mortgage. Locking in a well-negotiated 10-year rate today means securing for a decade conditions that the inflation trajectory described by the SNB could make rarer.
Refinancing strategy: forward rates in focus
For property owners whose mortgage is due to expire in 2026 or 2027, the key instrument is the forward rate: most lenders allow you to lock in the rate for a future renewal now, often without significant premium until six months before expiry, sometimes beyond. The SNB's status quo offers a window of visibility, not a guarantee of duration on long rates.
The approach involves three steps: obtain an assessment of your situation (current property value, debt-to-income ratio, maturity structure), compare offers from several lenders rather than defaulting to renewal with your current bank, and favour long durations while the term premium remains contained. This is precisely the work of an independent financial adviser: accessing negotiated conditions across the entire market and defending your file with lenders. RealAdvisor Finance regularly assists Swiss property owners in this reflection, particularly during pivotal market phases like the one following this decision.
