The world’s 100 largest asset managers grossed US$25.7 trillion in assets under management as of Dec. 31, 2021, up nine per cent from the previous year, according to a report by WTW’s Thinking Ahead Institute.

The report found pension funds remain the single biggest group of asset owners in the global study, controlling more than half (56 per cent) of total assets, though this percentage has decreased from 58 per cent in 2020. By contrast, sovereign wealth funds have seen their share rise to 37 per cent, up from 35 per cent the previous year.
