The Role of Private Credit in Today’s Corporate Defined Benefit Portfolio
Corporate defined benefit plans are entering a period of relative strength. Many plans remain well funded, or even in surplus. At the same time, de‑risking strategies have steadily shifted portfolios toward long‑duration public fixed income. For well‑funded plans, this sheds light on an underlying challenge that is most acute for heavily de-risked portfolios: traditional fixed income often does not keep up with year over year changes in the plan’s liability.
This return gap of about 50-100 basis points per year has historically been offset by return‑seeking assets such as equities or private equity.1 But as plans de‑risk and reduce those allocations, they are increasingly reliant on their liability‑hedging assets to maintain funded status. The question facing many CIOs and investment committees is how to re-evaluate portfolio construction in their return seeking and liability hedging portfolios to maintain their current funded status, without materially increasing funded‑status volatility.
We believe that private credit can help plan sponsors achieve this objective.
Expanding the liability hedging toolkit
Most liability‑hedging portfolios are built from long‑duration investment grade credit and Treasuries. These assets can match the duration and credit sensitivity of the liability well but often still lag liability growth. Plans that are no longer receiving cash contributions, or that maintain smaller return‑seeking allocations, feel this challenge most acutely.
This is where private credit can play a differentiated role. Senior direct lending strategies typically offer a meaningful spread advantage over public credit, while maintaining a similar cash‑flow profile. Seasoned loans accessed through credit secondaries add another layer of appeal, as they have already passed through the period when the majority of defaults tend to occur. For plans operating with tight risk budgets, this combination of higher yield with a cash flow profile aligned with shorter duration public credit strategies is worth careful consideration.
Private credit: A liability hedging enhancer
For plans that are already heavily de‑risked, the bar for making changes is high. Any new allocation must slot naturally into an established liability‑hedging framework.
In practice, this can be done. Substituting a portion of intermediate public investment grade credit with senior private credit can lift portfolio yield meaningfully. For example, the plan below has an 11-year liability duration and is using a combination of investment grade credit and treasuries to hit the duration and target of the liability. This portfolio is yielding 5% in today’s environment. By allocating to senior private credit, in place of shorter duration public credit, and adjusting the size and duration of the portfolio’s Treasury allocation the yield of the portfolio rises 80 basis points to 5.8%, while maintaining an 11‑year duration target.2 This incremental yield is enough to compensate for the margin by which a liability hedging portfolio typically lags the year over year changes in the liability.

We believe that credit secondaries can be especially attractive here. They provide exposure to seasoned, cash‑flowing loans with known performance histories and shorter remaining durations. That combination can offer qualities that align well with the needs of de‑risked pension plans: higher income, lower default risk, and a more predictable liquidity profile.
Supporting return‑seeking allocations while preserving optionality
Plans that are not yet fully de‑risked face a related but distinct challenge. Their return‑seeking portfolios—typically public equities and private equity—must generate returns that exceed liability growth, while still maintaining flexibility to adjust allocations over time as they gradually de-risk and re-allocate from return seeking strategies to liability hedging strategies. As many plans look to wind down legacy private equity allocations, we believe there are opportunities to capture an illiquidity premium in the private credit market in a manner that distributes regular cash flows, contractual liquidity and shorter fund terms.
We believe that private credit secondaries fit naturally into this allocation. They offer attractive risk‑adjusted returns, often in the low double‑digits, with more predictable liquidity and shorter fund lives than primary private equity commitments. Because secondary investments invest in seasoned credit portfolios, plan sponsors can mitigate the J-curve by deploying capital quickly, while receiving portfolio cash flows immediately to either fund benefit payments or to rebalance back to their strategic targets. This allows plans to keep the door open for future de‑risking decisions.
As you can see in the charts below, introducing a 25% allocation to private credit, taken proportionally from a public and private equity allocation, increases the risk adjusted return of this allocation, while introducing greater predictability of cash flows and a shorter duration of the private capital allocation.

The case for acting now
With funded statuses above 100% for the average plan, return seeking allocations shrinking, and lower base rates underpinning the public fixed income markets, today’s environment offers a timely opening for corporate pensions to revisit portfolio construction. Whether through direct lending or secondaries, private credit provides a versatile set of potential tools that can help plans:
- Increase yield in a controlled, liability aware manner
- Preserve and strengthen recent funded status improvements
- Add diversification beyond traditional public credit
- Enhance liquidity and the predictability of cash flows, relative to other private market strategies
- Maintain optionality as allocations continue to evolve
For plans aiming to protect their current position while preparing for the next stage of derisking, incorporating private credit thoughtfully into both the liability hedging and return seeking allocations can offer a meaningful advantage.
