First Abu Dhabi Bank has appointed banks to lead a U.S. dollar-denominated sukuk issue. Citi, First Abu Dhabi Bank, KFH Capital, NCB Capital and Standard Chartered will lead the deal, which has a five-year tenor. The sukuk is expected to be of benchmark size, which generally means upwards of $500 million. The bank, formed by a merger of National Bank of Abu Dhabi and First Gulf Bank, is tapping the sukuk market to diversify its funding sources. The planned debt sale would be part of the bank's $2.5 billion sukuk programme.
