S&P 1500 Pension Funded Status Increased by One Percent in July 

The estimated aggregate funding level of pension plans sponsored by S&P 1500 companies increased by one percent in July 2025 to 108 percent as a result of an increase in discount rates and domestic equities. As of July 31, 2025, the estimated aggregate surplus of $116 billion USD increased by $2 billion USD compared to a surplus of $114 billion USD measured at the end of June, according to Mercer,¹ a business of Marsh McLennan.

The S&P 500 index increased 2.17% percent and the MSCI EAFE index decreased 1.45% percent in July. Typical discount rates for pension plans as measured by the Mercer Yield Curve increased from 5.51 percent to 5.57 percent.

“Pension funded status for the S&P 1500 increased 1% in July, driven by US equity gains,” said Matt McDaniel, a Partner in Mercer’s Wealth Practice. “Interest rates ended the month slightly increased, as the market awaits the Fed’s next potential rate cut.”

“This year has seen several new insurers enter the pension risk transfer space, but annuity buyout volume has been lower than in recent years. These two factors have combined to produce a notably more competitive pricing environment, with some of the most attractive pricing we have ever seen in the pension risk transfer market.  Plan sponsors on the sidelines should consider taking advantage of this to cost-effectively reduce their long-term liabilities,” McDaniel added.

Mercer estimates the aggregate funded status position of plans sponsored by S&P 1500 companies on a monthly basis. Figure 1 (below) shows the estimated aggregate surplus/(deficit) position and the funded status of all plans sponsored by companies in the S&P 1500. The estimates are based on each company’s latest available year-end statement² and by projections to July 31, 2025, in line with financial indices. The estimates include U.S. domestic qualified and non-qualified plans, along with all non-domestic plans. The estimated aggregate value of pension plan assets of the S&P 1500 companies as of June 30, 2025, was $1.67 trillion USD, compared with estimated aggregate liabilities of $1.56 trillion USD. Allowing for changes in financial markets through July 31, 2025, changes to the S&P 1500 constituents, and newly released financial disclosures at the end of July, the estimated aggregate assets were $1.66 trillion USD, compared with the estimated aggregate liabilities of $1.54 trillion USD. Figure 2 shows the discount rates used in Mercer’s pension funding calculation.
