The United Nations General Assembly’s latest pension fund resolution — adopted at the end of December 2025 — has triggered concerns among current and former staff members of the organization that their retirement security may be at risk. The resolution invites the UN Pension Board to carry out a full review of the pension system, including consideration of defined-contribution and hybrid models and exploring ways to “lower contributions.”

That last phrase signals the review’s underlying intent: cost reduction rather than benefit enhancement. While framed as an “invitation,” the directive leaves the Pension Board with limited room to decline.

The current reported market value of the UN pension fund is $108.2 billion.

Initial readings of the resolution’s language about “respect for accrued rights” suggest that changes would affect only future UN employees. However, pension experts and staff representatives say that assumption may be misplaced.

Ian Richards, a staff representative on the Pension Board, issued a public warning on LinkedIn on Jan. 6, 2026, outlining potential risks of shifting from the current defined-benefit (DB) system to a defined-contribution (DC) model. These include lower investment returns and reduced pensions, closing the DB plan to new entrants, creation of a multitier system and potential new taxation on 401(k)-style accounts.

Michelle Rockcliffe, a former Pension Board member and ex-Pension Fund Benefits Officer, said in online commentary that real-world transitions from DB to DC systems often affect current employees. Typical transitions freeze or recalculate accrued service and push current staff into defined-contribution accounts going forward

What’s at risk

Against a backdrop of budget pressures and liquidity concerns at the UN, a recommendation to weaken or replace the current defined-benefit system after the review’s three-year timeframe is not unthinkable. The potential consequences are significant.

Current staff could lose guaranteed lifetime pensions, predictable benefit formulas and collective protection against market volatility and longevity risk (outliving one’s pension). Secondary effects could diminish cost-of-living adjustments, survivor benefits and disability coverage.

For retirees, changes could destabilize current pension payments, weaken adjustment mechanisms and transfer investment and longevity risks from the institution to individuals.

Pension policy analysts note that meaningful protection requires structural safeguards rather than assurances. These include legally binding provisions that lock in all earned benefits to date, maintain past service under the DB formula as a closed legacy plan, separate those liabilities from any new scheme, prohibit conversions without individual consent and mandate an independent legal and actuarial review with full transparency and formal participation by staff and retirees.

The Pension Board’s track record compounds skepticism about such a review process. In 2019, the Board shelved an independent report recommending governance and transparency improvements, dismissing it under the trope “if it ain’t broke, don’t fix it.”

The pension fund’s history also includes retaliation against staff representatives over alleged confidentiality breaches and termination of senior whistleblower investment officers. Last July, the Coordinating Committee for International Staff Unions and Associations (CCISUA) of the UN system passed a resolution criticizing lack of transparency and treatment of whistleblowers.

Ethical questions also arose when the former representative of the Secretary-General for Investments moved to a firm conducting business with the fund.
