Treasury auction: $95 billion of 13-week bills on the block

WASHINGTON — The Treasury Department held its regular Monday Treasury auction of 13-week bills on Oct. 5, offering $95 billion of the three-month paper, according to the department’s auction announcement. The bills settle on Thursday, Oct. 8, and mature on Jan. 7, 2027.

It is a routine event, but the weekly bill sale is one of the steadiest signals of how the government is funding itself at the short end of the curve.

Key takeaways

• Treasury offered $95 billion of 13-week bills (CUSIP 912797VS3) at auction on Oct. 5, 2026.
• The offering was announced Oct. 1 and is not a cash management bill (CMB), so it belongs to the regular bill schedule.
• The bills are issued Oct. 8 and mature Jan. 7, 2027, a term of 91 days.
• The announcement does not include results, so the stop-out rate and demand metrics are not covered here.

What Treasury announced

The announcement lists a single security: a 13-week bill with a $95 billion offering amount. Treasury announced it on Thursday, Oct. 1, and ran the auction on Monday, Oct. 5. Settlement follows on Oct. 8.

The listing says “CMB: No.” Cash management bills are irregular, short-dated issues that Treasury uses to cover temporary gaps in cash. A “no” means this is part of the standard, recurring bill calendar and not a one-off financing tool.

The maturity date of Jan. 7, 2027 falls exactly 91 days after settlement. That is the standard three-month span, and it places the bill’s payoff just after the turn of the year.

Why a Treasury auction of bills matters

Bills are the shortest-dated securities Treasury sells. They pay no coupon. Investors buy them at a discount to face value and receive the full face amount at maturity, so the return is the gap between the two. The auction’s stop-out rate, the highest accepted rate, feeds directly into short-term Treasury yields, which anchor money-market pricing.

Because three-month bills are rolled over so frequently, the size of each auction is a live gauge of financing needs. A larger or smaller offering than the week before shifts net cash flowing in or out of the market. It can also change how much short-dated paper money funds and other cash-heavy buyers have to absorb.

The announcement gives only this week’s $95 billion figure, with no comparison to prior weeks. Readers who want to judge whether supply is rising or falling will need to line this number up against the previous auctions in the series.

Who is affected

The most direct participants are money market funds, banks, dealers and corporate treasurers, who use bills as a place to hold cash that must stay liquid and safe. Their appetite helps set the auction’s clearing rate.

The effects spread further. Bill yields serve as a reference point for the front end of the yield curve. When bills cheapen or richen against expected policy rates, that shows up in how the broader bond market prices the near-term outlook.

How to read the result

The announcement is a pre-auction notice, so the outcome is not part of the source material. When results are published, three details are worth checking:

• The high rate. Compare it with the prior week’s 13-week auction and with where the bill traded before the sale. A clearing rate above pre-auction levels would suggest soft demand, and one below would suggest firm demand.
• The bid-to-cover ratio. This measures total bids against the amount offered. A higher figure signals more depth of demand.
• The allotment mix. The share going to dealers versus direct and indirect bidders shows how much of the supply reached end investors and how much dealers had to hold.

What to watch next

The next checkpoint is Thursday’s settlement on Oct. 8, when the new bills are issued and payments move. After that, watch the following week’s bill announcement. Any change in the 13-week offering size, a new cash management bill, or a shift in the three-month rate relative to longer maturities would say more about financing conditions and rate expectations than a single steady auction does. For now, a $95 billion offering on the regular calendar is a baseline against which the next results can be measured.
