Price Of The Front

The front of the ladder is bills. That slice refinances inside the year at the rate on this statement, not at the rate on an old note. This is the average rate on paper already outstanding. It is not next auction, not CBO net interest, and not a forecast.

SecurityAverage rateStock on this pageAs-of
Marketable bills3.870%$7.12T2026-09-30
Notes3.383%—2026-09-30
Bonds3.466%—2026-09-30
TIPS1.149%—2026-09-30
FRNs4.141%—2026-09-30

Average rates for Notes, Bonds, TIPS, and FRNs are on total marketable outstanding of that type, not on the wall slice. Only bills show stock + rate on this page (bill component of the wall).

Average rates: Treasury Fiscal Data, Average Interest Rates on U.S. Treasury Securities, same record date as the wall. Bill stock is the MSPD Table III bill component already on this page.

FYTD Interest expense lives on Receipts.

Monthly Maturity Ladder

Marketable CUSIPs from the same MSPD Table III file as the wall total, grouped by the month they come due. As of 2026-09-30. Not a forecast of issuance.

The front of the ladder is bills. Months further out only contain paper that has already been issued.

This is not next quarter's auction calendar. New bills are not on this file until they are outstanding in the next MSPD.

Months rounded to $0.01T; totals are the unrounded CUSIP sum.
