Surging Treasury yields don’t signal a U.S. 'fiscal apocalypse' - yet

Key Points:

• U.S. government borrowing costs have surged, with the 10-year Treasury yield rising above 5% and net interest expenses projected at about $1.05 trillion for fiscal year 2026, raising concerns about a potential fiscal crisis fueled by a debt-interest cost spiral.
• Experts warn that higher borrowing costs could lead to a vicious cycle where increased interest expenses force more borrowing, potentially causing debt to spiral out of control; however, some analysts believe the U.S. is not yet near a fiscal breaking point.
• The gradual maturity of existing debt and the fact that the average interest rate on U.S. debt (3.4%) remains below nominal GDP growth (8.5%) help moderate the debt burden, providing a buffer against immediate fiscal distress.
• Analysts attribute the rise in Treasury yields not only to fiscal concerns but also to factors such as strong economic growth, Federal Reserve rate hike expectations, higher oil prices, and market repositioning, with the economy's resilience playing a key role.
• While the risk of a fiscal crisis exists if economic growth slows significantly, experts note that the U.S. retains advantages like the dollar's global role, and historical examples like Japan show that high debt alone does not inevitably lead to crisis.
