What is the ruling on bank interest for savings certificates in light of the current economic conditions?

The ruling on the returns of investment certificates does not change with economic conditions, but rather with the true nature of the transaction between the bank and the certificate holder: whether it is a loan or a legitimate Mudarabah (profit-sharing partnership).

Certificates dealt with by Islamic banks, in accordance with Sharia guidelines, are permissible and their profits are lawful. As for certificates from interest-based banks, they are considered a loan, and their returns are usury (riba).
