US Treasury sparks debate over potential auction cutbacks as demand weakens
A $1.45 trillion funding gap looms over the next two fiscal years if the government sticks to its current playbook of holding auction sizes steady.
The Treasury announced it will hold coupon auction sizes steady through at least the end of fiscal year 2026, a decision that aligns with unanimous recommendations from the Treasury Borrowing Advisory Committee (TBAC).
The auctions that rattled the market
Late March 2026 delivered a string of underwhelming auction results across three key maturities. A $69 billion sale of 2-year notes produced a bid-to-cover ratio of 2.44, well below the recent average of roughly 2.62. Auctions of $70 billion in 5-year notes and $44 billion in 7-year notes told a similar story of tepid demand.
Primary dealers absorbed about 24% of the 2-year auction. The historical average sits around 11%.
The 10-year Treasury yield climbed from approximately 4.0% at the end of February 2026 to north of 4.4% by late March.

Holding the line, for now
The Treasury’s decision to keep auction sizes unchanged covers the standard refunding slate: $58 billion for 3-year notes, $42 billion for 10-year notes, and $25 billion for 30-year bonds. Modest adjustments to shorter-dated bill sizes will address immediate cash flow needs, but the longer-duration issuance stays flat.
TBAC minutes from August 5, 2026, confirmed that the committee sees current nominal coupon auction sizes as sufficient to meet projected financing needs through FY2026.
The $1.45 trillion question
Primary dealer forecasts indicate that if coupon auction sizes remain constant, the Treasury faces an anticipated funding shortfall of approximately $1.45 trillion across fiscal years 2027 and 2028.
