Rising oil prices push U.S. bond yields above 5%, raising concerns of a debt feedback loop
U.S. Treasury bond yields surged past the 5% threshold for the first time since 2023, driven by rising oil prices and ongoing geopolitical tensions in key shipping straits like Hormuz and Bab al-Mandab. The conflict has disrupted global energy flows, leading to higher crude prices—Brent crude reached nearly $110 a barrel—and elevated inflation expectations worldwide. With the Federal Reserve expected to raise interest rates soon, concerns are growing about how rising borrowing costs could create a self-reinforcing cycle of debt and fiscal strain. Economists warn that in an environment marked by high public debt and large deficits, higher bond yields may worsen government finances as servicing costs rise. This feedback loop could amplify the impact of supply shocks like the current oil crisis. While U.S. nominal GDP growth is still outpacing debt service costs for now, there are fears about long-term vulnerabilities in a highly indebted global economy. The surge in bond yields also threatens to weigh on tech stocks and AI-driven sectors that rely heavily on low borrowing rates. A Financial Times op-ed warned of an imminent risk of the AI investment bubble popping if 5% Treasury yields persist.
