According to the latest figures from the Federal Statistical Office (FSO), the national consumer price index rose by 0.2 percent in October compared with the previous month, reaching 101.7 points. Year-over-year, inflation rose from 1.0 percent in September to 1.5 percent in October. This increase was steeper than many economists had expected.
This was driven in particular by higher prices for heating oil, gasoline, and diesel. Petroleum products rose in price by about 40 percent compared with the same month last year. Core inflation, which excludes energy prices—which are prone to fluctuations—and other volatile components, remained unchanged at 0.5 percent.
Mortgage Rates Already on the Rise
For the real estate market, the key question is what impact higher inflation will have on interest rate trends. The Swiss National Bank (SNB) left its key interest rate at 0 percent in September. With an inflation rate of 1.5 percent, inflation remains within the SNB’s defined range of price stability of 0 to 2 percent.
However, long-term mortgage rates had already begun to rise even before the latest inflation report. According to the Comparis Mortgage Barometer, benchmark rates for 10-year fixed-rate mortgages rose from 1.77 to 2.07 percent in the third quarter of 2026. The main drivers were higher capital market interest rates and increased refinancing costs for banks.
Should inflation remain at elevated levels for an extended period, this could limit the Swiss National Bank’s room for maneuver in monetary policy. For homebuyers, project developers, and investors, a further increase in the cost of long-term financing would affect their profitability calculations.
Focus on Operating Costs and Rents
Rising energy prices are also affecting property management. Buildings with fossil-fuel-based heating systems are particularly affected by higher heating costs. For owners and property managers, energy efficiency, renovations, and long-term operating cost planning are thus becoming increasingly important.
The situation regarding residential rents is more nuanced. The reference mortgage interest rate remains at 1.25 percent. Higher consumer prices therefore do not automatically lead to increases in existing rents. However, within the framework of legal provisions, inflation can be partially factored into standard lease agreements.
Investors Must Calculate More Carefully
Institutional and private real estate investors face a dilemma. On the one hand, real estate can offer a certain degree of protection against inflation in the long term. On the other hand, rising financing costs and operating expenses weigh on returns unless they are offset by corresponding income or efficiency gains.
The current trend therefore does not yet signal an imminent shift in interest rates. Persistently low core inflation suggests that there is no broad-based price surge. The key factor will be whether the surge in energy prices eases in the coming months or spreads to other sectors of the economy.
For the real estate sector, interest rate trends thus remain a key focus. Careful cost calculations are likely to become even more important, particularly in the context of upcoming refinancings, major construction projects, and real estate acquisitions.
