Long-term borrowing costs in major economies like the U.S., Germany, and Japan have surged to multi-decade highs due to escalating government debt and geopolitical factors. The U.S. debt pile is approaching $40 trillion, contributing to investor concerns about fiscal sustainability. The ongoing war in Iran is also driving up oil prices, fanning inflation worries and hindering global economic growth. This environment of heightened inflation and interest rate uncertainty is exacerbated by U.S. President Donald Trump's policies, which are seen as disrupting the global order.
The U.S. bond market, a critical global benchmark, has seen its 10-year Treasury yield top 4.70%, touching its highest level in over a year before settling at 4.65%. The 30-year bond yields also reached their highest since 2007, with oil prices climbing back above $90. Treasury Secretary Scott Bessent announced measures to calm the market, including more than doubling the bond buyback program from $2 billion to $4 billion per operation, though initial market reaction saw yields rebound.
Analysts attribute the bond sell-off to investors' growing impatience with government fiscal profligacy and the uncertainty surrounding policymaking. Competition for capital from technology companies building AI infrastructure is also intensifying, further impacting demand for government bonds. The New York Fed estimates the term premium, or additional compensation for lending to the government for 10 years, is near its highest level in 12 years at around 80 basis points.
The rising bond yields have broad economic repercussions, pushing up borrowing costs for companies and households, including mortgage rates. Major stock markets, such as Nasdaq and Europe's STOXX 600, have seen declines. Concerns about the unpredictability of the U.S. Treasury's debt management strategy and doubts about the Federal Reserve's commitment to fighting inflation under its new Chair, Kevin Warsh, are also contributing to investor unease.
