US Stock Market: US Treasury's growing reliance on short-term bills sparks debate over borrowing risks

The US Treasury's growing reliance on short-term Treasury bills has raised concerns about refinancing risks amid widening federal deficits and higher interest payments. Net T-bill issuance in July has already reached around $270 billion, surpassing full-month forecasts, while Goldman Sachs expects total bill supply of about $827 billion in 2026. Bills now account for around 22 percent of outstanding US marketable debt, above the 15-20 percent range recommended by the Treasury Borrowing Advisory Committee, raising worries about interest rate exposure and limited flexibility during future crises.
