Is the recent improvement in corporate pension funding a sign that the national economy is strengthening?
The funded status of the 100 largest U.S. corporate defined benefit plans increased to 114.5% during September. This improvement occurred as rising interest rates reduced the present value of future obligations for these plans.
Why it matters
Pension plans are considered better funded when liabilities fall due to higher discount rates tied to corporate bond yields. For households, this trend highlights how shifts in market interest rates impact the long-term solvency of corporate benefit programs.
The Milliman Pension Funding Index reached 114.5% in September, up from 112.2% the previous month. This change was supported by a 47-basis-point increase in benchmark corporate bond rates, which helped reduce pension liabilities by $54 billion.
The players
Milliman
An actuarial and consulting firm that publishes the Pension Funding Index to track the financial health of large corporate benefit plans.
Federal Reserve
The central banking system of the United States that sets monetary policy, including overnight lending rates that influence market interest levels.
The details
Pension plans calculate their liabilities by discounting future payouts to their current value, a process heavily influenced by corporate bond rates. As benchmark rates climbed to 6.47% in September, the value of those future liabilities dropped significantly. Even though the market value of plan assets fell by $35 billion due to negative investment returns, the reduction in liabilities resulted in an overall healthier funded status for the 100 largest plans.
Timeline
May 2009 saw discount rates reach levels similar to those seen in September 2026.

September 2026 saw the funded status rise to 114.5%.
Money Landscape
The current environment for pension liabilities is defined by discount rates climbing to levels not seen since May 2009. This shift follows a broader trend where rising corporate bond yields provide relief to defined benefit plans by lowering their projected costs.
If you participate in a defined benefit pension plan, this data suggests your plan is likely in a stronger position than in previous months. Monitor your annual plan statement for updates on funding status and consult a financial professional regarding your retirement benefit security.
The takeaway
Rising interest rates have helped improve the funding health of large corporate pensions by reducing the present value of future payouts. Review your most recent summary plan description to understand how your specific pension fund communicates its current financial standing to participants.
