Funded pensions: the capital pools behind retirement
Some countries pre-fund retirement through asset pools; others promise it from future taxes. The gap is enormous and structural: in 11 countries, funded pension assets exceed a full year of GDP, led among the major systems by Denmark at 206% (Isle of Man, a scheme-administration hub, tops the full table at 269% of its small local GDP), while large pay-as-you-go systems like France and Germany hold funded assets worth only a small fraction of output. Across the 81 countries reporting 2024, the pools sum to $66.1 trillion. The second story on this page is American: five decades of Form 5500 filings that record the shift from defined-benefit promises to defined-contribution accounts.
Data as of 2024 (OECD), plan year 2023 (EBSA)
Funded pension assets as a share of GDP
Total investment of asset-backed pension plans (all plan types and financing vehicles) over GDP, each country at its own latest reporting year. The top of the table is the fully funded systems: Isle of Man (269%), Denmark (206%), Iceland (191%). Isle of Man's outsized ratio is a hub artifact: schemes administered there against a small local GDP.

Trajectories: growth, and the 2022 repricing
Eight funded systems, 1990 to 2024. The long climb is visible everywhere, but so is 2022: when rates rose, bond-heavy systems repriced hard. The Netherlands peaked at 210% of GDP in 2020 and stood at 151% in 2024, a fall of 59 points of GDP driven by losses on bonds and interest-rate hedges ahead of its pension-system transition, not by benefit cuts. Denmark, similarly bond- and guarantee-heavy, shows the same shape.

Who bears the risk: DB and DC across countries
In a defined-benefit (DB) plan the sponsor promises the pension and carries the investment risk; in a defined-contribution (DC) plan the member holds an account and carries it themselves. Share of pension assets in DC plans (protected plus unprotected), latest complete year per country; only the 26 countries whose published DB/DC decomposition sums to 100% are shown, so a missing component cannot masquerade as a small one (Switzerland, among others, is excluded for that reason).
Source: OECD Global Pension Statistics (Asset-backed pensions) DC = defined contribution assets (protected + unprotected); DB = defined benefit (traditional + hybrid/mixed). Countries with an incomplete published decomposition are excluded. Methodology
What the pools hold
Published asset-allocation shares for 6 of the 8 trajectory countries (the OECD serves no all-vehicle allocation for the rest), each at its own latest reported year. Direct holdings only: the mutual-fund column is not looked through, so a system that routes bonds via funds shows a large fund share rather than a large bond share.
| Country | Year | Equity | Bills and bonds | Cash | Mutual funds | Other |
|---|---|---|---|---|---|---|
| United States | 2024 | 38.4% | 12.5% | 1.5% | 29.5% | 9.5% |
| Australia | 2024 | 31.5% | 7.6% | 6.6% | 46.0% | 8.2% |

The American shift: defined benefit to defined contribution, 1975 to 2023
Five decades of Form 5500 filings, aggregated by EBSA, record the defining structural change in US private retirement. In 1975, DC plans held 28.5% of private pension assets; DC participants passed DB in 1992, DC assets passed DB in 1997, and by 2023 DC plans held 75.9% of the $12.4 trillion total and 94.5% of the 836,843 plans. The DB system did not vanish: 46,233 DB plans covering 29 million participants still held $3.0 trillion in 2023. But the risk moved: the account, not the promise, is now the American default.

Methodology
Methodology and caveats
Definitions. Funded (asset-backed) pensions accumulate assets to pay future benefits; pay-as-you-go systems pay current benefits from current contributions and hold few assets, so a low ratio here measures funding structure, not retirement generosity. The cross-country asset series is the OECD's total investment of asset-backed pension plans, its published proxy for assets, over GDP. DB plans promise a benefit and leave investment risk with the sponsor; DC plans are member accounts. The OECD DC category spans protected and unprotected variants; DB spans traditional and hybrid/mixed.
Sources and vintages. OECD Global Pension Statistics, dataflows "Asset-backed pensions - main database" and "Asset allocation" (OECD.DAF.CM DSD_FP), pulled from the OECD SDMX API on 2026-07-18: 148,230 observations, 96 jurisdictions, annual data to 2024; the assets-to-GDP series covers 94 jurisdictions. US series: EBSA Private Pension Plan Bulletin Historical Tables and Graphs 1975-2023 (September 2025 edition), tables E1/E4/E10 (441 parsed values, plan years 1975 to 2023), which is EBSA's own edited and delinquency-weighted Form 5500 universe. Raw plan-year-2023 Form 5500/5500-SF bulk files were pulled from askebsa.dol.gov as an order-of-magnitude cross-check of the plan count. Both sources refresh on the annual tier.
Coverage caveats. The OECD panel is unbalanced: cross-sections keep only countries reporting within 2 years of 2024 and label each country's own year; the USD total sums only the 81 countries reporting 2024. The OECD US aggregate includes IRAs and annuity reserves, so it is broader than the Form 5500 universe (private employer plans only: no IRAs, no government plans, no one-participant plans); their DC shares differ accordingly. The DB/DC ranking drops countries with incomplete decompositions rather than showing partial sums. EBSA participant counts double-count multi-plan members, and its methodology changed over five decades (documented in the bulletin's appendices); the 2004 participant revision is kept on the pre-revision definition for series continuity.
