Pension Risk Transfer Costs Edge Higher Despite Favorable Index Levels
Event summary
- Milliman's Pension Buyout Index (MPBI) indicates a slight increase in competitive pension risk transfer (PRT) costs, rising from 100.3% to 100.4% of accounting liabilities (ABO) in January 2026.
- The average annuity purchase cost also increased, moving from 103.4% to 103.5% of ABO.
- Plan sponsors are currently estimated to save 3.1% on PRT costs through competitive bidding.
- The MPBI has remained below 101% for nine consecutive months.
The big picture
The marginal increase in PRT costs, while small, signals a potential inflection point in a market that has been exceptionally favorable to plan sponsors. The Milliman Pension Buyout Index's continued tracking of this metric is crucial for understanding the evolving landscape of defined benefit pension plan de-risking strategies, particularly as interest rate volatility persists. This trend underscores the ongoing pressure on corporate treasuries to manage legacy pension obligations.
What we're watching
- Cost Sensitivity
- Further increases in interest rates or insurer capacity constraints could quickly erode the cost savings currently benefiting plan sponsors, potentially pushing the MPBI above 101%.
- Competitive Dynamics
- The continued reliance on the FTSE Above Median AA Curve as a benchmark suggests that shifts in broader credit markets will disproportionately influence PRT pricing.
- Index Sustainability
- The 3.1% cost savings from competitive bidding may prove unsustainable if insurer participation in the PRT market decreases, reducing competitive pressure.
