Bank Muscat, Oman's largest lender, has delayed plans to launch a 500 million rial ($1.3 billion) sukuk programme after the central bank rejected the proposal, a source at the bank said. The regulator informed Bank Muscat in writing that it would not accept the plans in their current form, which involved the lender asking for a single approval to issue 100 million rials a year for the next five years, the source said, adding that the central bank had concerns over plans to use the sukuk proceeds to increase personal lending. The bank will restructure the sukuk proposal and file for the approval again. The plans for the sukuk to be issued in various tranches was backed by Bank Muscat's shareholders in March.
