Saudi Arabia is expected to raise several billion US dollar sukuk across five and 10-year tranches. The notes will be in a hybrid mudaraba-murahaba format, a structure in essence already trialled by Saudi Aramco for a riyal-denominated sukuk. The kingdom is rated A1 by Moody's and A+ by Fitch. The banks running the deal are BNP Paribas, Citigroup, Deutsche Bank, HSBC, JP Morgan and NCB Capital. The national oil company Saudi Aramco raised SR11.25bn riyals in order to diversify its revenues impacted by low international oil prices. The floating rate local currency sukuk has a seven-year maturity and offers 25bp over the six-month Saudi Arabian Interbank Offered Rate.
