Bahrain has hired a group of banks to arrange calls with fixed income investors ahead of a planned U.S. dollar-denominated debt issuance, a term sheet reviewed by Reuters showed on Tuesday. The Gulf country is planning to issue 7-1/2-year sukuk, or Islamic bonds, and 12-1/2-year conventional bonds. It has mandated BNP Paribas, Citi, HSBC , JPMorgan, and National Bank of Bahrain to manage the debt sale. (Reporting by Yousef Saba, writing by Davide Barbuscia; editing by Christian Schmollinger)
