But with currency movements erasing all but a tiny portion of the local currency gains the survey's biggest retirement fund, Japan's $1.7 trillion Government Pension Investment Fund, reported last year — together with those of the country's $248.6 billion Pension Fund Association for Local Government Officials, which slipped to 14th place from 13th place on the back of a 0.2% gain — the world's 20 largest retirement plans saw their assets rise only 6.6% for the 12-month period, well below the top 300's 8.9% gain.
The same dynamic impacted regional totals, with Asia-Pacific funds seeing their share of the top 20's $9.68 trillion in assets drop to 41% from 43.7%, amid a 0.7% decline in their combined assets. The share of European funds fell to 26.5% from 28.4%, with their combined assets dipping 0.6% from the year before. U.S. funds' share of top 20 assets, by contrast, jumped to 26.1% in 2021 from 21.7% the year before, on the back of their 28.5% surge in combined assets.
The stronger dollar impacted medium-term regional results for the top 300 retirement funds as well. For the five years ended Dec. 31, annualized gains for that broader group's North American-based funds came to 9.2%, outpacing European and Asia-Pacific-based funds with 8.3% and 8%, respectively — a reversal from the prior year's rolling five-year results, when Asia-Pacific funds bested North American funds 9.9% to 7%.
The latest survey showed North America continuing to boast the largest pool of retirement assets, with a 45.6% share of the top 300's total last year, up from 41.7% the year before. Asia-Pacific funds dropped to 25.5% from 27.5%, while European funds fell to 25.9% from 27.5%.
