The Government Pension Fund of Norway comprises two entirely separate sovereign wealth funds owned by the government of Norway. The Government Pension Fund Global, also known as the Oil Fund, was established in 1990 to invest the surplus revenues of the Norwegian petroleum sector. It has over US$1 trillion in assets, including 1.4% of global stocks and shares, making it the world’s largest sovereign wealth fund. In May 2018 it was worth about $195,000 per Norwegian citizen. It also holds portfolios of real estate and fixed-income investments. Many companies are excluded by the fund on ethical grounds. The Government Pension Fund Norway is smaller and was established in 1967 as a type of national insurance fund. It is managed separately from the Oil Fund and is limited to domestic and Scandinavian investments and is therefore a key stock holder in many large Norwegian companies, predominantly via the Oslo Stock Exchange.
