Credit Downgrade: Markets Poised to Shake it Off

On Friday, Moody’s cut the United States’ long-term credit rating from Aaa to Aa1—matching similar moves by Standard & Poor’s in 2011 and Fitch in 2023. Moody’s cited persistent, large budget deficits for the move.

Markets took the decision in stride. The S&P 500 Index closed up slightly on Monday while the 10-year Treasury yield was little changed with the curve bear steepening.

Upheaval Unlikely

We see three reasons why the ratings action is unlikely to be particularly disruptive to markets.

1. It’s old news

The idea that the U.S. is on an unsustainable fiscal path is not new news. Every Fed Chair since Alan Greenspan in the mid-2000s has called out the problem in front of Congress. At the heart of it—underfunded entitlement programs and rising welfare costs as the population ages. This has been a slow-motion trainwreck for economists tracking the issue. For example, the nonpartisan Congressional Budget Office’s long-term projections have consistently showed a hyperbolic debt trajectory in the 2030s and 2040s. Higher interest rates post-2022 simply amplify this underlying dynamic.
