Government borrowing costs are surging globally, with US Treasury yields reaching levels not seen in decades. The 10-year Treasury yield, for instance, breached 5% for the first time since 2007, marking a significant increase from pandemic-era lows of around 0.52% in 2020. This rise is attributed to several factors, including investors demanding higher compensation for holding longer-maturity debt amidst concerns about escalating fiscal deficits and stubborn inflation.
The current high yields are driven by a combination of factors, including President Donald Trump’s trade war, increased energy costs stemming from the conflict in the Middle East, and ongoing inflation, with US CPI inflation at 3.4% annually in August, well above the Fed's 2% target. The Federal Reserve's interest rate hikes, federal deficits, and substantial Treasury issuance have also played a role in this reversal. Some analysts fear a return to 1970s-style stagflation, characterized by high inflation and weak economic growth.
The extraordinary monetary and fiscal responses to COVID-19, including the Fed cutting interest rates to near zero and purchasing vast amounts of government debt, initially led to record low yields. However, since late 2021, the 10-year yield has steadily climbed, moving above 4% in 2022 and then crossing 5% in September 2023. Despite a brief dip in late 2023 when investors anticipated a drop in inflation and Fed rate cuts, the recent leg of the selloff is linked to rising oil prices due to geopolitical tensions, further fueling inflation fears. Treasury Secretary Scott Bessent's expanded buybacks of long-dated government debt have not yet halted the upward trend in yields.
