Global Bond Market Faces 19-Year High Amid Inflation, Deficits, and Geopolitical Tension

Investors are rapidly selling government bonds, driving prices down and pushing yields up across major economies. The 30-year U.S. Treasury yield has risen to 5.34%, the highest level since 2007, while the 10-year yield sits at 4.74%, near the peak of President Donald Trump’s second term. Similar upward pressure is evident in Europe and Asia, with 10-year yields in France, Germany and Japan reaching their highest points in over a decade.

The sell-off reflects a confluence of factors. Persistent inflation and expanding government deficits have heightened investors’ demand for higher compensation on long-dated debt. The ongoing U.S.–Israeli conflict with Iran and a surge in oil prices have added geopolitical risk, prompting concerns that central banks may keep policy rates elevated for longer. At the same time, technology firms are issuing large volumes of debt to fund artificial-intelligence infrastructure, competing directly with sovereign issuers for the same pool of buyers. Adding to market uncertainty, Kevin Warsh’s recent appointment as Federal Reserve chairman has reduced forward guidance, leaving investors unsure about the future path of U.S. interest rates.

Analysts link the Middle-East conflict to heightened inflation worries and a deteriorating fiscal outlook. MUFG’s Derek Halpenny notes that the worsening situation in the region intensifies concerns over both inflation and the U.S. fiscal position, while also observing a lack of appetite for addressing fiscal challenges, which pressures the long end of the curve. Nigel Green of deVere Group warns that hyperscaler borrowing for AI infrastructure is crowding out government bond demand, raising the “price of patience” for all borrowers. Jonas Goltermann of Capital Economics describes the market’s reaction as a demand for higher compensation amid greater fiscal, geopolitical, and policy uncertainty.
