JAK Medlemsbank

JAK Medlemsbank is a Swedish member-owned cooperative bank that applies an interest-free model, offering loans without interest while charging fixed fees and, in many cases, requiring complementary saving either before and/or during the loan term; by law the total borrowing cost is still presented as an effective annual rate (APR) for consumer transparency. Deposits generally do not earn interest, and access to services requires membership with a joining and annual fee. The offering is focused on savings accounts and loans to private individuals, with a more limited range of payment and card services than universal banks and no marketed investment or credit card products. Credit decisions follow standard Swedish affordability and credit checks, and loan size is typically constrained by income, collateral and internal limits rather than by the absence of interest; some products may require security. Accounts are in SEK, operations are domestic, and onboarding typically requires a Swedish personal identity number; customer service and documentation are primarily in Swedish. The bank is supervised by Finansinspektionen, and deposits are covered by the Swedish deposit guarantee up to the statutory limit per person and institution. The structure means savers forego yield and face inflation risk, while borrowers pay upfront and ongoing fees and may need to maintain saving alongside repayment; comparing the effective total cost to conventional loans is necessary. As a small cooperative, scope of services, digital functionality and processing times may be narrower than at larger banks, and funding capacity is linked to member savings.
