The first SWF was established by Kuwait in 1953 as a means to help stabilize the economy from fluctuating oil prices. 20 In 1956 the Gilbert Islands (now Kiribati) established the Revenue Equalization Reserve Fund to manage profits from phosphate mining. Following Kuwait and Kiribati, the next major SWFs were created in the 1970s in the wake of the oil shock. The most recent wave began in the 1990s with the Norway Government Pension Fund-Global in 1990 and continues to this day. In the last five years, funds have been established by China, Iran, Russia, Qatar, and the United Arab Emirates
