Global pension assets across 22 major markets reached a record $68.3 trillion at end-2025, rising 9.6% in a single year, according to the Thinking Ahead Institute’s Global Pension Assets Study published February 9, 2026. The six largest systems in this analysis collectively held approximately $57 trillion, covering roughly 25 cents on every dollar of the $224 trillion they are projected to owe by 2050.
The WEF’s 2017 landmark study, reaffirmed at Davos in January 2025, projected that the six largest pension economies will face a combined shortfall of $224 trillion by 2050. The US alone accounts for $137 trillion of that gap, more than 60% of the total across the six countries. Across all retirement systems globally, the WEF estimates that the savings gap is widening by $28 billion each day.
OECD countries currently have 33 people aged 65 and over for every 100 working-age adults. By 2050, that figure rises to 52 per 100, according to OECD Pensions at a Glance 2025. The underlying workforce ratio has collapsed from 7.2 workers per retiree in 1950 to a projected 2.1 by 2050, a 71% decline in the support base over one century.
The US Social Security trust fund is now projected to deplete between 2032 and 2033, according to the Congressional Budget Office and the 2025 Trustees Report. At depletion, incoming payroll revenue covers only 77% of scheduled benefits. The WEF’s original six-country study calculated the average individual shortfall at $300,000 per person across these markets.
The modern pension system was built for a world that no longer exists. When most state pension programs were codified in the post-World War II era, average life expectancy in the United States was 68 years. The retirement age was 65.
The system was designed around a three-year retirement window. Today, a 65-year-old in a high-income country can expect to live another 20 years.
The pension system was never redesigned to accommodate that shift. It was simply asked to pay for it.
Global pension assets reached $68.3 trillion at the end of 2025, the highest level ever recorded across the 22 major markets tracked by the Thinking Ahead Institute. The six economies at the core of this analysis collectively held approximately $57 trillion. Against a projected 2050 liability of $224 trillion, those six systems cover roughly 25 cents on the dollar.
The World Economic Forum’s landmark retirement study, first published in 2017 and reaffirmed at Davos in January 2025, projected a combined $224 trillion shortfall by 2050 across the world’s six largest pension systems: the United States, United Kingdom, Japan, Netherlands, Canada, and Australia. When the WEF first measured the US gap in 2017, it stood at $28 trillion. By 2050, that figure is projected to reach $137 trillion.
That makes the US responsible for more than 60% of the entire six-country gap. The remaining five systems, the UK, Japan, the Netherlands, Canada, and Australia, share $87 trillion between them. Across all retirement systems worldwide, the WEF estimates that the combined global shortfall is widening by $28 billion each day.
The structure of this gap matters more than the headline number. Pension fund assets are held in liquid, investable form. The liability is embedded in law, the social contract, and political commitment.
Governments cannot restructure pension obligations the way a corporation renegotiates a bond covenant. France’s decision in 2023 to raise the statutory retirement age by just two years, from 62 to 64, triggered the most sustained civil disruption that country had seen in decades.
In 1950, there were 7.2 working-age people supporting every retiree across OECD countries. The model functioned because the workforce was large, growing, and the retirement period was short.
By 1980, that ratio had fallen to 5.1, and by 2010 to 4.1. It is projected to reach 2.1 by 2050, according to OECD data.
OECD Pensions at a Glance 2025, published in November 2025, gives the clearest operational read: 33 people aged 65 and over exist per 100 working-age adults across OECD countries today. By 2050, that rises to 52 per 100, up from just 22 in the year 2000.
The WEF’s Global Risks Report 2025 adds the acceleration context: the global population aged 65 and over is projected to grow from 857 million today to 1.2 billion by 2035. That is 343 million additional people arriving in a single decade, each one carrying a claim against systems funded for a shorter-lived, smaller-cohort world.
Average global life expectancy rose from 67 years in 2000 to 73 years in 2019 and is projected to surpass 77 by 2050, according to WEF data published in July 2025. Every decade since the 1940s, life expectancy has increased by roughly 3 years.
Contribution schedules and retirement ages have not kept pace with each other. The WEF’s six-country study calculated an average individual shortfall of $300,000 across these markets.
The $68.3 trillion in global pension assets is deeply concentrated. The United States alone accounts for approximately 66% of all tracked assets across the 22 major markets, an estimated $45 trillion at end-2025.
The next three markets, Japan, Canada, and the United Kingdom, hold roughly another 16% combined. Australia, the Netherlands, and Switzerland account for most of the remainder among major markets.
The table below uses end-2024 country-level data from the WTW Thinking Ahead Institute Global Pension Assets Study 2025, alongside OECD Pensions at a Glance 2025 replacement rate data. The first six entries are the WEF study group that underpins the $224 trillion gap projection. The remaining markets are in a broader comparative context.
Countries marked with an asterisk use OECD-confirmed GDP percentages. All others are calculated from WTW asset data divided by 2024 nominal GDP.

Several entries in this table carry immediate market implications. Germany holds pension assets equivalent to only 14% of GDP and operates almost entirely on a pay-as-you-go basis, meaning current workers fund current retirees with no buffer of pre-accumulated capital.
South Korea recorded a fertility rate of 0.72 in 2023, the lowest ever measured in any country in modern demographic records. Japan’s working-age population has been contracting for over a decade. Both systems face compounding demographic pressure with no significant funded reserve to absorb it.
Japan’s mandatory public pension delivers a net replacement rate of approximately 36% for average earners. Despite holding $3.3 trillion in assets through GPIF, Japan’s ratio of workers to retirees has already fallen below 2 to 1 and continues declining, the worst demographic trajectory of any G7 economy.
India presents a structurally different challenge from the Western systems in this analysis. It's $270 billion in pension assets, which cover approximately 8% of GDP, and formal pension provision reaches fewer than 30% of the workforce, leaving the majority of workers dependent on informal family support in old age. India has approximately 148 million people aged 60 and over today, a figure the UN projects will surpass 320 million by 2050.
The Western systems in this article face a funding crisis for promises they made over decades. India faces a coverage crisis: it never built comprehensive formal provision for the majority of its workers, and demographic aging is accelerating faster than the system is expanding.
The United Kingdom’s pension market provides the most instructive example of what structural fragility looks like under sudden stress. In September and October 2022, the rapid spike in gilt yields following the Truss government’s mini-budget exposed catastrophic leverage inside liability-driven investment strategies. Pension funds faced margin calls that they could not cover.
The Bank of England intervened with emergency gilt purchases to prevent a systemic collapse. That was not a failure of any individual fund. It was the result of a defined-benefit architecture that had silently accumulated duration mismatch across decades of low returns.
Governments are already delivering less than what workers were told to expect. OECD Pensions at a Glance 2025 confirms that workers entering the labor market today and completing a full career will receive an average net pension of 63.2% of their net wages across OECD countries.
Four OECD members, Estonia, Ireland, South Korea, and Lithuania, deliver net replacement rates below 40%. Australia, which holds $2.6 trillion in pension assets and runs the world’s most sophisticated compulsory superannuation system, delivers under 35% for average-wage workers.
These figures are not projections. They are the legally enshrined outcomes that current law delivers to today’s 25-year-olds.
In the United States, the arithmetic has become explicit. The 2025 Social Security Trustees Report, published in June 2025, confirmed the combined trust fund depletion date under official assumptions as 2033, with a 23% across-the-board benefit cut taking effect automatically at that point. The Congressional Budget Office, in a February 2026 update, moved that date forward to 2032, citing the revenue effects of the One Big Beautiful Bill signed July 4, 2025.
The 75-year financing shortfall is now estimated at $25 trillion. In 1960, there were more than five workers per Social Security beneficiary. In 2025, that ratio stood at 2.7 and is still falling.
The pension crisis does not arrive as a single shock. It accumulates through a compounding sequence that governments in every major economy have consistently postponed addressing.
Aging populations require more pension spending year after year. More spending forces more sovereign borrowing. Higher yields that follow reduce the value of bond-heavy pension portfolios.
Lower portfolio returns widen the funding shortfall. Wider shortfalls pull more governments into intervention. Each round of intervention adds to the sovereign debt load that drives yields higher in the next cycle.
The OECD projects global sovereign borrowing at $29 trillion in 2026 alone. US federal debt interest crossed $1 trillion annually for the first time in 2024. The governments being asked to backstop pension shortfalls are the same governments already spending more on servicing existing debt than on defense.
The shift from defined benefit to defined contribution plans, which now represent 63% of assets in the seven largest pension markets, up from 40% two decades ago, transfers the accumulated risk from institutions to individuals. Workers who retire into a prolonged bear market, who outlive their savings assumptions, or who never earn enough to build meaningful DC balances will not have an employer or government to absorb the difference. They will have what they saved.
In the United States, the average Generation X worker between 45 and 60 has saved approximately $150,000, according to data cited at Davos 2025 by State Street Investment Management CEO Yie-Hsin Hung. The WEF’s six-country study puts the average individual shortfall at $300,000. Forty percent of Americans in that age group have no retirement savings at all.
The WEF’s framing of this as the financial equivalent of climate change holds in one precise respect: incremental interventions can defer the adverse effects. Raising contribution rates by 1%, lifting retirement ages by two years, adjusting investment allocations: each measure buys time. None of them reverses the underlying demographic arithmetic.
A government that publicly acknowledges its pension system is underfunded by tens of trillions will pay a risk premium on every bond it issues. Every government sitting on a serious gap has a fiscal incentive to postpone that acknowledgment for as long as the political cost of honesty exceeds the cost of delay.
Approximately $57 trillion in pension assets is spread across the six largest economies, most of which are exposed to this shortfall. Against $224 trillion owed by 2050, that covers about 25 cents on the dollar.
The most consequential financial disclosures of the next decade will not come from earnings calls or central bank minutes. They will come from governments that can no longer avoid the arithmetic. France’s two-year adjustment to the retirement age nearly brought down a government in 2023.
The UK gilt market nearly collapsed under pension fund leverage in 2022. Both events occurred in systems that, by global standards, are relatively well-funded.
The US carries $137 trillion of the $224 trillion gap, more than 60% of the total, and its primary trust fund is projected to run dry within seven years. The pension system was not broken by mismanagement. It was broken by success, by people living 20 years longer than the architects of the post-war social contract ever assumed they would.
The question for markets in 2026 is not whether this shortfall materializes. It is which governments acknowledge it first, and what bond markets do when they do.
Data note: This article uses the WEF’s six-country retirement savings study (United States, United Kingdom, Japan, Netherlands, Canada, and Australia) as its primary analytical framework, projecting a $224 trillion combined gap by 2050. Global pension asset figures ($68.3 trillion, end-2025) are from the WTW Thinking Ahead Institute’s Global Pension Assets Study published February 9, 2026. Country-level asset figures in the table use end-2024 data, the most granular verified breakdown currently available.
