Effective regulation and supervision of Islamic banks achieved through a dedicated unit of the Central Bank of Oman (CBO) is positive for the sector as it should strengthen early detection of risks and support growth, Fitch Ratings said. The central bank inaugurated its specialist department for overseeing Islamic banking last week. The department will build up resources and expertise and centralise all aspects of Islamic banking regulation and issuance. Although the industry represents just over five per cent of total banking assets in Oman, it could grow rapidly, as it has in neighbouring countries where market shares range between 20 to 30 per cent, the ratings agency said. The global ratings agency added that a limited number of Omani corporates have issued sukuk and the country's banks may follow.
