Sweden

Sweden's banking system is large relative to the economy and dominated by three domestically headquartered universal banks, SEB, Handelsbanken and Swedbank, alongside Nordea, which is headquartered in Finland but remains one of the largest lenders in Sweden through its Swedish branch. At end-2025 the sector comprised 128 banks, including 41 savings banks and 39 branches of foreign banks. The five largest credit institutions held 54.8% of sector assets in 2025 on ECB data, and Finansinspektionen reports that seven banks account for more than 80% of lending to the public.

Mortgage lending is the core of the domestic business, and housing loans are largely funded through covered bonds issued by the banks and their mortgage subsidiaries; the Riksbank describes the covered bond market as central to the Swedish financial system. Household debt remains high by international standards, although the debt-to-income ratio has fallen back to its level of ten years ago. Around 80% of household loans carry variable rates, the highest share since Statistics Sweden began measuring, so bank margins and borrowers' debt service respond quickly to changes in the policy rate.

The large banks remain highly profitable and well capitalised. For 2025 SEB reported a return on equity of 13.8%, Handelsbanken 13.0% and Swedbank 15.2%, with year-end CET1 ratios of 17.6–17.8%. FI's Bank Barometer shows that sector profitability declined in the second half of 2025 as net interest income fell with lower policy rates and costs rose. Credit losses remain minimal: Finance Sweden calculates that annual loss rates were close to zero over 2015–2025, the lowest among its European comparator countries.

The main vulnerabilities identified by the Riksbank and FI are exposures to highly indebted commercial real estate companies with short interest-rate fixation periods, household sensitivity to higher rates, dependence on international funding and rising cyber threats. In its May 2026 Financial Stability Report the Riksbank warned that a prolonged war in the Middle East could combine higher inflation and interest rates with weaker growth, while judging that the major banks meet capital and liquidity requirements by a wide margin. It has also called for an income-based borrower tool such as a debt-to-income limit.
