U.S. Corporate Pension Funding Surplus Grows to $109 Billion in January — Milliman, Inc.

Event summary

Milliman's January 2026 Pension Funding Index shows corporate pension assets rose by $8 billion (1.05%) to $1.327 trillion.
Liabilities fell by $2 billion due to a 1-basis-point rise in discount rates to 5.47%, improving the funded ratio from 108.2% to 109%.
This marks the 10th consecutive month of improved funding ratios for the top 100 U.S. corporate pension plans.
Optimistic forecasts predict a funded ratio of 121% by end-2026, while pessimistic scenarios warn of a drop to 92% by 2027.

The big picture

The sustained improvement in corporate pension funding ratios reflects broader market gains and shifting interest rate environments. With assets now exceeding liabilities by $110 billion, plan sponsors face strategic decisions on surplus deployment—whether to de-risk portfolios, contribute excess funds elsewhere, or adjust benefit structures. The divergence between optimistic (121% funded) and pessimistic (92%) forecasts underscores the sensitivity of pension health to macroeconomic conditions.
