Swiss National Bank Keeps Its Policy Rate at 0% in September 2026

The Swiss National Bank left its policy rate at 0% on 24 September 2026 and forecasts inflation of 0.7% this year, 0.8% in 2027 and 0.8% in 2028.

The Swiss National Bank left its policy rate unchanged at 0% in its monetary policy assessment of 24 September 2026. Consumer price inflation has edged up from 0.6% in May to 0.8% in August, and the bank now forecasts 0.7% for 2026, 0.8% for 2027 and 0.8% for 2028. It expects the Swiss economy to grow between 1.5% and 2% this year and around 1.5% in 2027.

One thing this release does not do is mention housing. The assessment is a pure rates and inflation document; it contains no statement on mortgage lending or residential property. The property reading below is therefore ours, drawn from the rate itself rather than from any claim by the bank.

Zero is the reference price of Swiss mortgage money

A policy rate of 0% is the anchor beneath some of the cheapest residential borrowing in the developed world. With inflation running at 0.8% and forecast to stay there for two more years, the bank has left itself no obvious reason to move, which is a way of saying that Swiss mortgage pricing is unlikely to be repriced upward by monetary policy in the near term.

For a Swiss owner that is comfortable. For an international investor comparing markets, it is the input that explains why Swiss yields look the way they do, and the explanation is not flattering to the yield.

The yield arithmetic is unusually tight

Our Swiss national row, in its 22 September 2026 snapshot, carries an asking price of 9,468 USD per square metre for the apartment segment, converted from 7,719 Swiss francs per square metre, with a published range of 4,631 to 10,807 francs. The matching asking rent from the same dataset is 23.30 USD per square metre a month, converted from 19 francs. Those two figures produce a gross yield of roughly 3.0%, before any cost, before any vacancy and before any tax.

That is the practical consequence of a zero policy rate applied to housing for years on end: capital values have been bid up against rents that cannot follow, so the income return compresses. Our twelve-month price trend for Switzerland is 4.5% in francs and 1.2% once the currency move is stripped out, prices are 18.8% higher than five years ago and 38.7% higher than ten, and our bubble-risk reading is 73 out of 100, in the elevated band.

The access question comes before the yield question

Switzerland is also the market where a foreign buyer's first problem is not the return but the permission. Under the Lex Koller rules, a non-resident needs a permit to acquire residential property, and permits are limited by canton and by purpose. That constraint has not changed with this rate decision and it is the reason Swiss housing behaves less like an internationally traded asset than its price level would suggest.

Where a purchase is possible, the cost side is unusually friendly. Transaction costs run to 6.1% of the price, low for Western Europe, and the effective tax on a non-resident's rental income is around 5.6%, among the lowest we record anywhere. Our confidence rating for the Swiss row is Medium, because the price and rent pair comes from a single national property-services publisher rather than a statistical office, even though both sides of the pair come from the same dataset and the same segment.
