What Is a Sovereign Wealth Fund (SWF)?
https://www.investopedia.com/terms/s/sovereign_wealth_fund.aspA sovereign wealth fund is a state-owned investment fund comprised of money generated by the government, often derived from a country's surplus reserves. SWFs provide a benefit for a country's economy and its citizens.
The funding for a SWF can come from a variety of sources. Popular sources are surplus reserves from state-owned natural resource revenues, trade surpluses, bank reserves that may accumulate from budgeting excesses, foreign currency operations, money from privatizations, and governmental transfer payments.
In general, sovereign wealth funds usually have a targeted purpose. Some countries have sovereign wealth funds that can be similar to venture capital for the private sector.
