Government borrowing costs are rising globally, with investors demanding higher compensation for holding longer-maturity debt. The yield on 10-year US Treasuries has surpassed 5%, marking its highest level in nearly two decades. This trend is driven by concerns over mounting fiscal deficits, persistent inflation fueled by President Donald Trump's trade war and Middle East conflict-induced energy costs, and increased competition for investor capital from technology companies issuing debt for AI infrastructure buildout. Treasury Secretary Scott Bessent's efforts to expand buybacks of long-dated government debt have not halted this rise.
Several factors contribute to this shift. The US is borrowing more to finance its over $40 trillion national debt and to cover an annual fiscal shortfall estimated at $2.1 trillion by the Congressional Budget Office. The term premium for 30-year US sovereign bonds, representing the extra yield investors require for long-term debt, has climbed by over three percentage points since its 2020 low during the COVID-19 pandemic. This rise in yields is also seen as a normalization to pre-Global Financial Crisis levels, as yields were near zero when the economic growth outlook was poor.
Analysts are reassessing the outlook for growth, inflation, and policy rates, noting that strong nominal growth, rather than just fiscal concerns, is a primary driver of elevated yields. Healthy household and corporate balance sheets have allowed the economy to withstand energy shocks, tighter monetary policy, and trade disruptions without a significant drop in spending. While some refer to this as "higher for longer," many economists, including Wells Fargo's Tom Porcelli and Michael Pugliese, describe it as "normal for longer," viewing current yields as a return to more historically typical macroeconomic conditions rather than an anomaly.
This trend has broad implications. Long bond yields influence interest rates on consumer loans like mortgages and corporate debt, potentially increasing pressure on household borrowers already contending with inflation. However, higher yields are beneficial for bondholders, and with equity markets at record highs, this rise also reflects a resilient global economy capable of absorbing increased borrowing costs. US business activity is expanding at its fastest pace in over five years, propelled by new orders, contributing to expectations of potential interest rate hikes.
Global bond markets are interconnected, with the acceleration in US rates impacting yields worldwide. Japan's 10-year bond yield reached its highest since 1996, and Germany's 10-year bund saw its highest yield since 2009. A recent S&P Global report highlighted that US business activity accelerated in September, but firms' input costs, particularly for fuel and transport, jumped at the steepest rate in four years. Despite interventions by the Treasury Department, such as planned buybacks of up to $6 billion in 20- to 30-year bonds, bond yields have continued to rise, indicating that market forces are strong.
