WASHINGTON / RankWire.AI / – The U.S. Treasury Department is scheduled to conduct three debt auctions next week, offering a total of $119 billion in notes and bonds. The series begins on Oct. 6 with a $58 billion auction of three-year notes. On Oct. 7, Treasury will sell $39 billion worth of 10-year notes. The final auction on Oct. 8 will involve $22 billion of 30-year bonds. These offerings follow Treasury’s usual financing timetable and align with the sizes outlined in its latest quarterly refunding schedule.
The three-year note, which is a new issue, will mature on Oct. 15, 2029. Meanwhile, the 10-year note auction will involve the reopening of an existing 4.625% security maturing on Aug. 15, 2036. The 30-year bond auction will also reopen an existing security, this time a 5.125% bond maturing on Aug. 15, 2056. Reopening an existing security boosts the outstanding amount while maintaining the original coupon rate and maturity date. Investors may submit either competitive or noncompetitive bids following Treasury’s standard auction procedures.
All three securities are set to settle on Oct. 15, in accordance with the published schedule from the U.S. Treasury Department. Competitive bidders specify the yield they are willing to accept for each security, while noncompetitive bidders agree to accept the yield determined at the auction. The Treasury releases detailed final pricing and bidding data after each sale concludes, typically including the high yield, accepted bids, and allocation details. These notes and bonds pay fixed interest and are a significant part of the federal marketable debt portfolio.
US Treasury schedules three consecutive debt issuance events
This October series follows the September auctions for the same 10-year and 30-year securities. On September 9, the Treasury sold $39 billion of the 10-year note, which yielded a high of 4.834%. The bid-to-cover ratio was 2.71, with bids totaling approximately $105.8 billion. This note carries a 4.625% coupon and matures in August 2036. The upcoming October reopening will add another $39 billion to the existing amount outstanding.
Similarly, on September 10, the Treasury sold $22 billion of the 30-year bond, which had a high yield of 5.308%. Investors bid approximately $57.5 billion, resulting in a bid-to-cover ratio of 2.61. The bond offers a 5.125% coupon and matures in August 2056. The October auction will add another $22 billion of this security, with the final yield, price, and demand data to be published after the sale concludes on Thursday.
Match between auction sizes and October financing goals
The upcoming auctions are part of a broader borrowing strategy for the last quarter of 2026. Treasury projected $628 billion of net marketable borrowing for October through December, based on an assumed year-end cash balance of $850 billion. The federal government funds marketable debt through routine sales of bills, notes, bonds, and other securities. Treasury manages issuance levels across different maturities within its established financing framework and publishes auction schedules and borrowing estimates to keep investors informed.
The total of $119 billion corresponds with the amounts listed in Treasury’s August financing plan for October. That schedule proposed $58 billion of three-year notes, $39 billion of 10-year notes, and $22 billion of 30-year bonds. The sequence begins with the three-year auction on Tuesday, followed by the 10-year on Wednesday, and the 30-year on Thursday. Treasury will issue official results after each auction, including the pricing, yield, and demand figures related to next week’s three U.S. government debt offerings.
