Al Rayan Bank UK has priced its £250mn Islamic bond "Tolkien Funding Sukuk No 1" at 80 basis points over three-month Libor (London Inter-bank Offered Rate). The transaction is secured by a portfolio of prime UK, first-charge, owner-occupied, home purchase plans, originated by Al Rayan Bank. The sterling-denominated sukuk has an expected called weighted average life of three years. Proceeds raised from the sukuk issuance would be used by Al Rayan Bank to fund further growth in its asset book, which has increased by more than 23% over the last 12 months. Such residential mortgage backed securities (RMBS) are relatively rare in Islamic finance. The bank believes that there would be more opportunities to issue sukuk in the future and a higher potential for other Islamic banks to tap into the RMBS market.
