U.S. Treasury to Issue $153 Billion Today
The U.S. Treasury will issue approximately $153 billion in government bonds on October 6, 2026, consisting of $95 billion in 6-month Treasury bills and $58 billion in 3-year notes. The 3-year notes are new issues, with a settlement date of October 15.
On the same day, there will be a 6-month auction at 11:30 AM, a 3-year auction at 1 PM, and a maximum of $4 billion in coupon bond repurchases at 2 PM. The repurchase targets bonds maturing between October 2028 and September 2029. A $39 billion 10-year and a $22 billion 30-year bond will be issued on October 7 and 8, respectively, both as reopenings, with a total of $119 billion in medium to long-term bonds also settling on October 15.
Pre-auction yields are significantly higher than the last round. The 3-year yield is about 4.957%, compared to the last round's highest bid yield of 4.474%, an increase of about 48 basis points. The 10-year yield is about 5.300%, up from 4.834% in the last round. The 30-year yield is about 5.660%, compared to 5.308% previously. The curve has flattened, with the front end and belly giving the most.
The bid-to-cover ratio for the last 3-year auction was 2.72 times, with an average of 2.65 times over six auctions. The tail was negative 0.1 basis points, with an average of negative 0.3 basis points over six auctions. Primary dealers took 10.9%, and direct bidders took 26.9%. These are old results, not today's bids.
The Treasury estimates that net marketable borrowing held by the private sector from October to December will be $628 billion. Short-term debt continues to roll weekly. The latest investment rates for 4-week, 6-week, 26-week, and 52-week bills are 3.956%, 4.044%, 4.314% (sold on October 5), and 4.616%, respectively. In the past 30 days, short-term debt auctions totaled about $22.4 trillion over 27 sessions.
The seller is the Treasury, while buyers include money market funds, banks, and foreign official accounts that need to absorb the short end, as well as bond funds that need to reprice the 3-year notes. The event is driven by the increased rollover of maturing debt and large new issuances, not temporary additions. Beneficiaries are buyers locking in close to 5% for the 3-year notes. Those under pressure are holders of old bonds facing a yield increase from 4.474% to 4.957%, as well as primary dealers who will also need to take on 10-year and 30-year bonds in the same week. The repurchase of up to $4 billion does not offset the $153 billion supply.

The Treasury's supply path is characterized by rolling short-term debt and large coupon issuances. On October 6, $95 billion in 6-month and $58 billion in 3-year notes are issued together, followed by $39 billion in 10-year reopenings and $22 billion in 30-year reopenings over the next two days. The increased proportion of short-term debt after 2023 is aimed at avoiding a one-time expansion in the long end. The 3-year notes are still new issues, while the 10-year and 30-year are reopenings, all settling on October 15.
Funds are flowing from money market funds and bank reserves to the Treasury's cash account. The 6-month bills are rolling over, while the 3-year notes lock in a new term close to 5%. The Treasury also announced a repurchase of up to $4 billion in coupon bonds maturing between 2028 and 2029, effectively issuing $153 billion while buying back less than $4 billion. The motivation is to fill cash lows while providing some demand for the long end. The estimated net borrowing held by the private sector in Q4 is $628 billion, with the $119 billion in medium to long-term debt this week being just a portion of that.
This is analogous to the Treasury concentrating its issuance on short-term debt in Q3 2023, which led to a repricing of term premiums, similar to the phase in 2018 when short-term debt supply pushed up repurchase rates. The current situation is a supply test, not a default trade. The 3-year yield is already about 48 basis points higher than the last round, with the discount given before the auction.
Structurally, this represents a transfer of pricing power. The issue price is no longer determined by the previous round's 4.474% but by today's marginal buyer willing to take on $58 billion. The mechanism is that rolling short-term debt occupies the balances of banks and money market funds, while the medium to long-term debt settles in the same week, putting primary dealers' balance sheets under pressure on both sides. The repurchase size is only about 2.6% of the issuance amount, and any portion that cannot be absorbed becomes yield.
