But as the global population grows older, and the COVID-19 pandemic accelerates the already rising number of retirees, there is still a large degree of variance in the quality of public pension plans around the world. Which countries have invested in robust public pension programs, and which lag behind? This graphic, using 2021 data from Mercer CFA Institute Global Pension Index, compares retirement income systems worldwide.

How the Index Ranks Pension Plans

Because a country’s pension system is unique to its particular economic and historical context, it’s difficult to draw direct comparisons. However, there are certain elements that pension experts see as universally positive, and that lead to better financial support for older citizens. As with previous rankings, Mercer and the CFA Institute organized these universal elements into three sub-indexes:

Adequacy: The base-level of income, as well as the design of a region’s private pension system. Sustainability: The state pension age, the level of advanced funding from the government, and the level of government debt. Integrity: Regulations and governance put in place to protect plan members.

These three measures were used to rank the pension system of 43 different countries, representing more than 65% of the world’s population. This year’s iteration of the index notably includes four new countries—Iceland, Taiwan, UAE, and Uruguay.

The Full Ranking

When it comes to the best pension plans across the globe, Iceland, the Netherlands, and Denmark have the top three systems. Iceland’s system ranks high across all three sub-indexes. The country offers a state pension with two components: mandatory contributions from both employees and employers, and optional contributions to state-approved pension products. Its system has a high contribution rate, which ultimately results in a generous state pension that retirees in Iceland can tap into. The country also has a relatively low gender pension gap, meaning the difference between the average female pension versus male pension is relatively small—especially compared to other OECD countries.

On the opposite end of the spectrum, the Philippines, Argentina, and Thailand scored the lowest on the ranking. Thailand scores particularly low in the adequacy category, with a score of 35.2. To increase its score, Thailand could increase the minimum payments for its poorest demographic and include more employees in occupational pension schemes.

Recommendations for Better Pension Plans

According to the index, countries seem to be steadily improving their pension systems. From 2020 to 2021, the average score of the overall index increased by 1.0. With an average of 60.7, the index shows that most countries’ systems have some good features, but they also have some significant shortcomings that could be addressed by the following recommendations:

Boosting adequacy by increasing coverage, and including more employees in private pensions systems. Increasing sustainability by adjusting retirement pension age to reflect increasing life expectancy, and promoting higher workforce participation from older citizens. Raise integrity by introducing policies that reduce the gender pension gap and discrepancies amongst minorities.

Countries that implement even a few of these changes could make a huge difference for their next generation of retirees—and those that don’t could be in trouble in the near future. on Despite economic uncertainty, pension funds saw relatively strong growth in 2021. The world’s 100 biggest pension funds are worth over $17 trillion in total, an increase of 8.5% over the previous year. This graphic uses data from the Thinking Ahead Institute to rank the world’s biggest pension funds, and where they are located.

What is a Pension Fund?

A pension fund is a fund that is designed to provide retirement income. This ranking covers four different types:

Sovereign funds: Funds controlled directly by the state. This ranking only includes sovereign funds that are established by national authorities. Public sector funds: Funds that cover public sector workers, such as government employees and teachers, in provincial or state sponsored plans. Private independent funds: Funds controlled by private sector organizations that are authorized to manage pension plans from different employers. Corporate funds: Funds that cover workers in company sponsored pension plans.

Among the largest funds, public sector funds are the most common.

The Largest Pension Funds, Ranked

Here are the top 100 pension funds, organized from largest to smallest. U.S. fund data are as of Sep. 30, 2021, and non-U.S. fund data are as of Dec. 31, 2021. There are some exceptions as noted in the graphic footnotes.

Japan’s Government Pension Investment Fund (GPIF) is the largest in the ranking for the 21st year in a row. For a time, the fund was the largest holder of domestic stocks in Japan, though the Bank of Japan has since taken that title. Given its enormous size, investors closely follow the GPIF’s actions. For instance, the fund made headlines for deciding to start investing in startups, because the move could entice other pensions to make similar investments. America is home to 47 funds on the list, including the largest public sector fund: the Thrift Savings Plan (TSP), overseen by the Federal Retirement Thrift Investment Board. Because of its large financial influence, both political parties have been accused of using it as a political tool. Democrats have pushed to divest assets in fossil fuel companies, while Republicans have proposed blocking investment in Chinese-owned companies. Russia’s National Wealth Fund comes in at number 19 on the list. The fund is designed to support the public pension system and help balance the budget as needed. With Russia’s economy facing difficulties amid the Russia-Ukraine conflict, the government has also used it as a rainy day fund. For instance, Russia has set aside $23 billion from the fund to replace foreign aircraft with domestic models, because Western sanctions have made it difficult to source replacement parts for foreign planes.

The Future of Pension Funds

The biggest pension funds can have a large influence in the market because of their size. Of course, they are also responsible for providing retirement income to millions of people. Pension funds face a variety of challenges in order to reach their goals:

Geopolitical conflict creates volatility and uncertainty High inflation and low interest rates (relative to long-term averages) limit return potential Aging populations mean more withdrawals and less fund contributions

Some pension funds are turning to alternative assets, such as private equity, in pursuit of more diversification and higher returns. Of course, these investments can also carry more risk. Ontario Teachers’ Pension Plan, number 18 on the list, invested $95 million in the now-bankrupt cryptocurrency exchange FTX. The plan made the investment through its venture growth platform, to “gain small-scale exposure to an emerging area in the financial technology sector.” In this case, the investment’s failure is expected to have a minimal impact given it only made up 0.05% of the plan’s net assets. However, it does highlight the challenges pension funds face to generate sufficient returns in a variety of macroeconomic environments.
