Qatar this week appointed Mansoor bin Ebrahim Al Mahmoud as CEO of its $320bn Qatar Investment Authority (QIA) – the tenth largest sovereign wealth fund. Mr Mahmoud replaces Sheikh Abdullah Bin Mohammed Al Thani who has been appointed a minister of state after four years at the helm. The QIA was founded in 2005 and developed a reputation for aggressive, high-profile dealmaking under CEO and Prime Minister Hamad bin Jasim al-Thani (HBJ). Since Emir Tamim took the throne in 2013 and replaced HBJ the following year, QIA has adopted a less brash approach that will likely be maintained by Mr Mahmoud. The new CEO previously served as head of risk management at the fund and is on the board of two subsidiaries – Diar and Hassad Food.
