Citigroup has inaugurated its regional headquarters in Riyadh, Saudi Arabia, aiming to secure government contracts and tap into the kingdom's $1 trillion Public Investment Fund. This strategic move is part of Saudi Arabia's Vision 2030, which seeks to diversify the economy beyond oil. Citigroup's expansion into Riyadh positions it to enhance its influence in the Middle East and North Africa, joining over 20 major financial firms that have recently established regional headquarters in Saudi Arabia.
