Swedish mortgage borrowers are still facing a wide price gap between banks, and the difference is large enough to move household finances by thousands of kronor a year.
Swedish Mortgage Rates Gap Widens Across Banks
A new Zmarta comparison of average rates at 13 banks shows Skandiabanken offering the lowest floating mortgage rate in August at 2.58%, while Ikano Bank sat at the top of the list at 2.93%. On a SEK 3 million loan, that 0.35 percentage-point spread amounts to roughly SEK 10,500 a year before tax relief, underscoring how aggressively lenders are still competing for mortgage customers even as broader rate expectations remain elevated.

The comparison matters because Swedish households are highly exposed to floating-rate borrowing, and mortgage pricing feeds directly into disposable income, housing demand and bank earnings. For borrowers, the gap is not abstract: Zmarta calculates the spread at about SEK 3,500 per year for every SEK 1 million borrowed, a meaningful hit at a time when living costs remain under pressure.
The data also points to a growing divide between floating and fixed borrowing costs. The average three-year mortgage rate was unchanged at 3.32%, but the five-year rate rose from 3.45% to 3.56%. Zmarta said the wider gap reflects market concern about future rate increases, suggesting lenders are demanding more compensation to lock in funding for longer terms.
Among fixed-rate offers, Swedbank had the lowest average three-year rate at 3.11%, while SEB led the five-year category at 3.29%. At the other end, Länsförsäkringar Bank was the most expensive on both horizons, at 3.52% for three years and 3.81% for five years.
For banks, the spread is a competition issue as much as a funding issue. Cheaper mortgage pricing can help lenders win market share, but it can also squeeze margins if deposit costs or wholesale funding remain sticky. For households, the picture is more straightforward: the cheapest bank can save a borrower real money, while the wrong choice can leave them paying materially more over the life of the loan.
The broader backdrop is one of cautious central banking and shifting rate expectations. Even if policy rates do not move sharply lower in the near term, lenders are already pricing in uncertainty around the future path of borrowing costs. That keeps mortgage comparison sites relevant and suggests Swedish borrowers will continue to benefit, or suffer, from small changes in bank pricing.
The immediate investor takeaway is that mortgage competition remains intense, but the trend toward higher fixed-rate pricing hints that banks see less room to ease lending terms aggressively. Borrowers with larger loans and shorter refinancing horizons are likely to remain the main beneficiaries of rate shopping.
