Treasury Expected to Hold Auction Sizes Steady
Primary dealers broadly anticipate no change to coupon auction sizes at the quarterly refunding announcement on Wednesday.
Updated on Nov. 2, 2026 in Economic Indicators
The US Treasury is widely expected to leave coupon auction sizes unchanged at its quarterly refunding announcement on Wednesday, November 4. The Treasury has said it will hold coupon sizes steady for the next several quarters.
Why it matters
Elevated yields on long-term Treasury debt have led to speculation that policymakers may look for ways to slow their climb, including trimming long-dated issuance. Primary dealers' expectations for future cuts shape how markets price the government's borrowing plans.
Treasury buybacks of 10- to 20-year debt have been increased to as much as $6 billion, against a US fiscal year 2026 deficit of $1.992 trillion. The timing of any future coupon auction changes remains unresolved, with primary dealers pointing to 2027 and the earliest possible change in August 2027.
The players
US Treasury
The US Treasury Department conducts the government's debt auctions and sets the schedule and size of Treasury bond and note offerings.
Wells Fargo
Wells Fargo is a major US bank whose analysts forecast the T-bill share of the Treasury market could reach 24% over the medium term.
J.P. Morgan
J.P. Morgan is a global investment bank whose analysts project the 2027 US deficit will remain unchanged at $1.960 trillion.
TD Securities
TD Securities is the investment banking arm of Toronto-Dominion Bank and forecasts $678 billion in net bill supply for November 2026 to January 2027.
The details
The Treasury asked primary dealers in a questionnaire what future changes to auction sizes should be considered, and dealers broadly expect cuts to 20-year and 30-year bond auctions while boosting 2-year to 10-year issuance. The Treasury will release its quarterly financing estimates on Monday, followed by the refunding announcement on Wednesday.
Timeline
Monday: Treasury releases quarterly financing estimates.
Wednesday, November 4: Quarterly refunding announcement expected, covering financing for Q4 2026 and Q1 2027.
November 2026 to January 2027: TD Securities forecasts $678 billion in net bill supply.
August 2027: Earliest possible timing for any coupon auction size changes.
Economic Indicators Context
The Treasury Borrowing Advisory Committee recommends the T-bill share stay between 15% and 20%, well below the post-World War Two average of 23%, while Wells Fargo projects it could reach 24% over the medium term. Whether the Treasury leans further into bills or trims long-dated coupons will shape how that share moves.
Changes to Treasury auction sizes influence the interest rates on government borrowing, which can ripple into mortgage and loan rates households pay. Investors holding long-term Treasury bonds would see the most direct effect if long-dated issuance is trimmed.
The takeaway
Watch the refunding announcement on Wednesday for any signal on whether long-dated Treasury issuance will be trimmed. Shifts in that mix can affect yields that borrowers and investors feel directly.
What happens next
The Treasury's quarterly refunding announcement is scheduled for Wednesday, November 4, and will set financing plans for Q4 2026 and Q1 2027.
