The Swedish Financial Supervisory Authority (Finansinspektionen, FI) has published new statistics on the average and dispersion of mortgage interest rates at Sweden’s eight largest mortgage banks to help borrowers compare offers and negotiate terms. The data highlights that rates differ not only between banks but also significantly between individual borrowers within the same bank. For variable-rate mortgages, the average rate was 3.10% in April 2025, and the difference between the banks with the lowest and highest average rates was 0.47 percentage points, corresponding to more than SEK 9,000 a year in interest costs on a SEK 2 million loan. FI also reported that only three in ten borrowers regularly compare their mortgage rate and stated that the new “average and spread of mortgage interest rates” publication replaces its previous reporting of banks’ gross mortgage margins.
