SNB interest-rate decision of 18 June – what owners and buyers should know

Most likely still a zero rate

The SNB has held its policy rate at 0 percent since March 2026. The large majority of surveyed economists expect it to remain unchanged throughout 2026; only over the longer term is a moderate increase anticipated. For mortgages this means a calm environment: the SARON reference rate barely moves, and multi-year fixed-rate mortgages remain at a low level – a five-year fixed mortgage currently sits at around 1.5 percent.

What it means for your financing

A stable low-rate environment buys time for a considered strategy. The key question remains: SARON or a fixed-rate mortgage? If you value planning certainty over many years, a fixed-rate mortgage locks in today’s low rates. If you can tolerate fluctuations and expect rates to stay low, a SARON mortgage keeps you flexible. Often a combination makes sense, for instance to stagger renewal dates. It is also worth looking at amortisation and affordability – precisely because low rates create room for solid debt reduction. The 18 June decision is unlikely to bring surprises, but it is a good moment to review your financing thoroughly.
