The U.S. Government's Credit Rating Just Got Downgraded for the Third Time Since 2011. History Says the Stock Market Will Do This Next.

Core Viewpoint - Moody's downgraded the U.S. government's credit rating from "Aaa" to "Aa1," marking it as the last major credit rating agency to do so, following S&P Global and Fitch [1][2] Group 1: Credit Rating Downgrade - The downgrade reflects concerns over growing fiscal deficits and elevated total debt, with the U.S. running over a $1.8 trillion deficit in fiscal year 2024 and having over $36 trillion in total debt [3][4] - Moody's indicated that the U.S. fiscal performance is likely to deteriorate compared to its past and other highly rated sovereigns, with expectations of larger deficits as entitlement spending rises [3][4] Group 2: Future Projections - Fiscal deficits could reach 9% of GDP by 2035, up from the current 6.4%, while total debt is projected to rise to approximately 134% of GDP, surpassing levels seen during World War II [4] - Annual interest payments on the debt, which accounted for 18% of revenue in 2024, are expected to increase to 30% by 2035 [4] Group 3: Legislative Impact - House Republicans' proposal to make temporary tax cuts permanent could add an estimated $4 trillion to the fiscal deficit over the next decade, excluding interest payments [6] Group 4: Market Reactions - Historical responses of the S&P 500 to previous credit downgrades show initial sell-offs followed by recoveries, indicating that the market may not react severely to the downgrade [7][10] - The muted market response to the recent downgrade may be attributed to prior warnings from Moody's and the established understanding of the U.S. debt situation [11]
