SNB Keeps Interest Rates at Zero

The Swiss National Bank (SNB) left its policy rate unchanged at 0% at its June meeting, in line with market and our own expectations. As a result, the focus of the meeting was less on the rate decision itself and more on the SNB's communication regarding inflation, the strength of the Swiss franc, and its readiness to intervene in foreign exchange markets if necessary. For financial markets, the key takeaway was that the SNB made a modest upward revision to its inflation outlook without signaling any change in policy direction.

Inflation remains under control

Recent price data continue to point to a well-contained inflationary environment. Consumer prices rose 0.6% year-on-year in May, coming in slightly below market expectations. Core inflation remains moderate at 0.3%. While the SNB nudged its 2026 inflation forecast up to 0.6%, this still falls comfortably within its target range of 0–2%. The strong franc continues to act as a key dampening force, limiting second-round effects.

Switzerland's electricity mix – heavily reliant on hydropower and nuclear energy – also provides a partial buffer against the oil price shock stemming from the conflict in the Middle East. This effect is primarily limited to electricity prices, however. Fuel and heating oil remain tied to crude oil prices and feed directly into the national consumer price index. On balance, there is nonetheless good reason to expect inflation to stabilize near current levels in 2026 and 2027. Relative to other central banks – the ECB in particular – the SNB finds itself in a comparatively comfortable position.

Communication in focus

Since inflation remains in the lower portion of the target range, a change in policy direction carries little urgency from a price stability standpoint. The exchange rate therefore remains the central focus. Throughout the year, the SNB has signaled a heightened willingness to intervene in foreign exchange markets. Crucially, however, intervention is not triggered by a specific exchange rate level, but by a rapid and excessive appreciation of the franc. The SNB is therefore most likely to act during abrupt currency moves, while a gradual franc adjustment is less likely to prompt intervention. This logic is more important to understanding future FX market activity than any single rate level.

Growth remains positive but subdued

The real economy equally provides no case for a policy shift. Real GDP growth of approximately 1% is projected for 2026. The SNB characterizes near-term economic momentum as muted, while anticipating a partial recovery over the medium term. The Middle East conflict remains a meaningful source of uncertainty, though Switzerland's economic structure offers certain advantages relative to its peers, and the inflationary impact of the energy shock has so far remained limited.

Implications for interest rates and credit markets

The decision confirms a near-term environment of stable, low interest rates. As long as the SNB keeps its policy rate at zero and its communication does not shift noticeably in a more restrictive direction, we view the probability of an imminent rate hike as low – even as swap rates continue to price in a residual risk of tightening by year-end.

For domestic financing conditions, this means stability for the time being, with the mortgage market as a primary beneficiary. Fixed-rate mortgage yields have held steady in recent weeks, following the normalization of more aggressive rate-hike expectations that had emerged at the onset of the Middle East conflict. The question of whether a SARON-linked or fixed-rate mortgage is the better choice today has no universal answer. The decision depends on individual financial circumstances, time horizon, and risk tolerance – and the right interest rate strategy should be calibrated accordingly.

"The SNB has the luxury of being able to wait and see at a time when other central banks are under pressure to act. It is staying its course, and rightly so. Inflation has ticked up modestly, but remains in the lower portion of the target range, core inflation stays subdued, and the energy price shock is feeding through far less forcefully in Switzerland than in the Eurozone. We continue to view the market-implied probability of a rate hike by year-end as ambitious, and we expect the policy rate to remain stable through at least the end of 2026. For savers, this means the low-rate environment persists and cash holdings continue to lose value in real terms. For mortgage borrowers, however, there is no compelling reason to rush into fixed-rate products."

"Switzerland's interest rate environment remains an outlier by global standards: low, stable, and highly predictable. For real estate investors, this is a meaningful advantage, as attractive financing conditions continue to support the asset class. At the same time, this favorable rate backdrop is playing out in a market already defined by constrained supply and strong institutional capital inflows. Today's SNB decision reinforces the tailwind for Swiss real estate investments and supports the case for another positive year for the asset class."
