The United States is home to the world’s largest and most dominant financial markets, yet its retirement security system is lagging behind. According to the 2025 Mercer CFA Institute Global Pension Index, which evaluates 52 national systems representing two-thirds of the global population, the U.S. ranks No. 30. With a score of just 61.1, the American retirement infrastructure receives a mediocre C+ grade, exposing critical gaps in how the nation supports its aging workforce.
Understanding the Mercer Index Pillars
The index evaluates retirement systems based on three core pillars:
- Adequacy: The level of benefits provided to retirees and the design of the system to ensure basic income security.
- Sustainability: The capacity of the pension system to continue delivering benefits in the future, factoring in demographic shifts and government debt.
- Integrity: The quality of governance, operational regulation, and trust in the system’s administration.
While the Netherlands secured the top spot with a score of 85.4, followed by Iceland at 84 and Denmark at 82.3, the U.S. struggled significantly—particularly in sustainability.
The Structural Divergence: U.S. vs. Global Leaders
The core weakness of the U.S. system lies in its structural shift from defined-benefit pensions to defined-contribution schemes like the 401(k) and IRA. Historically, traditional pensions provided guaranteed lifetime income. Today, the onus of saving for retirement has shifted almost entirely to the individual, creating a “do-it-yourself” retirement culture.
Social Security serves as the primary safety net, supporting 63 million Americans. However, with an average monthly payment of $2,071 as of January, it was never designed to be the sole income source. Compounding this challenge, the Social Security retirement trust fund is projected to run out by 2032 without legislative intervention, threatening future benefit reductions.
Replicating Elite Systems: Creating Guaranteed Income
Top-tier systems in the Netherlands and Iceland mandate contributions and automatically convert accumulated wealth into reliable lifetime income streams. Jan Gleisner, president of Hafnia Financial, notes that while U.S. accounts are excellent for wealth accumulation, they lack a universal conversion layer.
To bridge this gap, American investors must construct their own two-tiered retirement floor:
- The Security Layer: Converting a portion of assets into guaranteed income via lifetime annuities, Treasury bonds, or certificates of deposit (CDs).
- The Growth Layer: Keeping a segment of the portfolio in dividend-paying stocks and ETFs to combat inflation.
According to Northwestern Mutual’s 2026 study, Americans believe they need $1.46 million to retire comfortably, yet 46% do not expect to be financially ready. Managing claiming ages for Social Security is also vital: taking benefits before full retirement age (FRA) can reduce checks by up to 30%, whereas delaying until age 70 yields an 8% annual boost.
Frequently Asked Questions (FAQ)
Why did the U.S. receive a C+ grade on the Mercer Pension Index?
The U.S. score of 61.1 is driven down by a lack of mandatory retirement plans, the decline of defined-benefit pensions, and the projected insolvency of the Social Security trust fund by 2032.
How do systems in the Netherlands and Iceland differ from the U.S.?
These countries feature mandatory occupational pension participation and automatic mechanisms that transition accumulated savings into guaranteed lifetime income, reducing the risk of retirees outliving their assets.
What can individuals do to improve their retirement security in a DIY system?
Retirees can replicate stronger global systems by diversifying their portfolios with guaranteed options like lifetime annuities, optimization of Social Security claiming ages, and maintaining growth-oriented investments like dividend ETFs.
