The Oman Investment Authority (OIA) is a fully government-owned sovereign wealth fund that operates as an independent legal entity serving as the primary investment arm of the Sultanate of Oman. Established by royal decree, it functions under the direct oversight of the Council of Ministers, with its board chaired by senior government officials appointed by the state. Rather than being owned by private shareholders or individual commercial investors, the OIA manages public funds, state-owned enterprises, and national reserves collectively on behalf of the Omani government, aiming to generate long-term financial returns and foster economic diversification away from strict petroleum reliance.
