Government borrowing costs have reached their highest levels since the 2008 financial crisis, with the 10-year U.S. Treasury yield surpassing 5% to hit 5.041%, its highest point since 2007. The average 10-year yield for G7 economies also hit 4.285%, the highest since mid-2008. This surge is attributed to the tension between growing global debt and resilient economic growth, alongside market expectations of continued central bank tightening to combat inflation.
Major central banks, including the Federal Reserve, the European Central Bank, and the Bank of Japan, have recently raised interest rates, signaling more increases are likely. The Fed hiked rates by a quarter point, with 16 out of 18 policymakers anticipating at least one more hike by year-end. The ECB also raised rates last week, with a December hike expected, and the Bank of Japan increased its policy rate to 1.25%, the highest since 1995. These actions are seen as central banks reinforcing their commitment to fighting inflation.
The rising bond yields are further exacerbated by factors such as elevated oil prices, high government debt levels, and increasing private sector competition for capital, particularly from AI-related companies. Analysts warn that the global rebuilding of term premia is ongoing, and markets may still price in a more aggressive path of central bank rate hikes. The 10-year German Bund yield rose to 3.500%, below its peak of 3.572%, and the 10-year U.K. gilt yield climbed to 5.275%, below its peak of 5.493%.
There's a potential feedback loop in the bond market where adverse supply shocks, like soaring oil prices, push up inflation expectations, compelling central banks to hike rates. Higher rates then lead to increased government bond yields, raising concerns about fiscal sustainability, especially in highly indebted economies. This can create a self-reinforcing cycle where rising yields amplify fiscal worries, further driving yields higher.
