Are rising government deficits pushing bond markets toward a breaking point?
Core argument: U.S. deficits averaged 6.2% of GDP in 2023–2026 vs. 4.8% in 2010–2019, driving 30-year Treasury yields to 19-year highs of.
Government borrowing—everywhere, and especially in the U.S.—has been out of control for years. Inflation in the U.S. has been stuck above the Federal Reserve’s 2% target since 2022. Add in heavy corporate borrowing to fund the AI build-out, and you wonder why long-term interest rates aren’t higher. To be sure, the selloff has been mild in the scheme of things. The 30-year Treasury yield hit a 19-year high of 5.18% Tuesday [before retreating several bps]. Yet the more closely watched 10-year yield, at 4.67%, was lower than in October 2023. Both dropped back Wednesday on hopes oil will resume flowing through the Strait of Hormuz.
