Midyear Liability-Driven Investing Outlook: What’s Next for Corporate Pensions?

For many years, the pension plan has often been a drag on a corporation’s financial positions. Now that’s generally no longer the case, and it’s time to consider what’s next.

Corporate pension plans mostly find themselves in a strong position, thanks to evolving strategies over the past 25 years. After we review the current landscape, let’s consider what may be on the horizon for these plans.

Despite spikes of volatility in the first months of 2025—VIX peaked above 50 and MOVE above 140, highs since the pandemic and over the last couple of years, respectively—markets and corporate pension funding levels have remained fairly stable through the first half. The Milliman 100 Pension Funding Index began the year at 103.6% and ultimately rose to 104.9% at the end of May—a funded level we haven’t seen since before the global financial crisis in 2008 and the tech bubble in 2001.

How do we view the environment for pension investing?

Throughout the year, as broad market bonds have slightly outperformed US equities, market returns and liability returns have combined to leave funded ratios in a now familiar spot. Long bonds have produced slightly lower returns than US equities and broad market bonds. That’s consistent with liability returns below equities and broad market bonds, given that their duration is typically on the longer side.

This may look like where we started the year, yet lower returns for long bonds than for broad market bonds point to an interesting shift: For years, market yields had been relatively flat across maturities. Since the beginning of 2025, yield curves have steepened markedly. Through May 31, the 2-year/30-year yield spread shifted from 53 to 102 basis points (bps), and the 5-year/30-year spread went from 41 to 97 bps.

While yield levels still have the most influence on bond and liability returns, the slope of the curve is showing more impact now than for quite some time. We think this warrants monitoring as we move forward.
