What is the ruling of Islamic law on dealing with a Swedish bank that claims to offer interest-free savings and lending services, but requires saving in exchange for borrowing, and takes an annual administrative fee of 1.5% of the loan amount, given the dire need for this loan?

The bank's condition of saving with them in exchange for lending, and taking an annual percentage on the loan, calling it services or administrative fees, are both usury (riba). This is because "every loan that draws a benefit for the lender in exchange for the loan is usury." It is not permissible for the increase to be tied to the loan amount or its duration, otherwise, it would be usury, except in cases of dire necessity.
