Sovereign Wealth Funds (SWFs) are special-purpose investment funds that have no or limited liabilities and are owned by the central government. Typically, this definition includes funds that exist as part of a central bank or are held by the central bank of the state. In their policy brief for T20 Saudi Arabia, experts of the Valdai Club and King Fahd University of Petroleum & Minerals propose creation of a platform that would bring together the sovereign wealth funds of the G20 countries, which would encourage the G20 states to strengthen their economic cooperation, bolster mutual interests, and improve multilateralism.
