Profits (return) in the form of rental payment (ujroh) with a fixed amount in each period, are the advantages of ijarah Islamic bonds, because they can guarantee certainty of profits received in each period, in any conditions. In addition, the amount of profit that is known at the beginning of the issuance of Islamic bonds, makes it easier for issuers to manage funds originating from the issuance of ijarah Islamic bonds.
