The Global Pension Assets Study estimates global pension fund assets across 22 major pension markets (the P22). These geographies now total a record US$56.6 trillion in pension assets and account for 76% of the GDP of these economies. The study, conducted by WTW and the Thinking Ahead Institute since the 1990s, includes an analysis of the seven largest markets (the P7): Australia, Canada, Japan, Netherlands, Switzerland, UK and US comprise 92% of total pension assets, unchanged from the previous year.
