The Islamic Development Bank (IDB) has appointed nine banks to arrange a new Islamic bond issue likely to be in excess of $1 billion. The mandated banks include Boubyan Bank, Credit Agricole, Gulf International Bank, JP Morgan, Mizuho, Natixis, NBAD, RHB and Standard Chartered for a five-year debt issue. The mandate was given at the end of last week and the notes will be sold only after the U.S. elections on Nov. 8. IDB sold its last U.S. dollar-denominated sukuk in March. That issue, of $1.5 billlion, offered 50 basis points over midswaps and was priced at par at 1.775 percent.
