When Rates and Valuations Collide

Equities thrive when discount rates are low. Cheap capital inflates the present value of future cash flows, giving companies more leeway to finance growth and investors more willingness to pay higher multiples. That dynamic was the backdrop of the post–Global Financial Crisis era, when ultralow interest rates and accommodative policy helped propel equity valuations to record highs.

However, the landscape has changed. With the Federal Reserve holding policy rates above 4% and the 10-year Treasury yield trading in the 4.3–4.6% range for much of 2025, equities face the gravitational pull of higher discount rates. The tailwind of cheap money is gone, and valuations now stand at the mercy of earnings growth and investor confidence.

One of the clearest signals of this new regime is the compressed equity risk premium — the spread between the S&P 500’s earnings yield and the yield on 10-year Treasurys. Currently, the S&P 500’s forward earnings yield is roughly 4.1%, while the 10-year Treasury yield is about 4.3%. At -20 basis points, one of the narrowest readings in two decades, the negative equity risk premium is highlighting how much harder equities have to work to justify their valuations in a rising rate environment.

This matters because the equity risk premium represents compensation for taking on the inherent uncertainty of stocks versus the relative safety of bonds. Historically, investors have expected a much larger spread. For example, during the early 2010s, the equity risk premium often exceeded 300 basis points, reflecting both low Treasury yields and investor skepticism in the wake of the financial crisis.

When the spread narrows, it signals one of two things: either equities are priced for very optimistic outcomes, or Treasurys offer unusually attractive alternatives. In today’s case, both dynamics may be at work. For equities to maintain current valuations, earnings growth must remain resilient even as borrowing costs rise and the consumer softens.
