Key takeaways

The Daily Treasury Statement for October 15 recorded $449,175,000,000 in deposits and $400,307,000,000 in withdrawals, a net inflow of $48,868,000,000.

The debt number

Yesterday the Ledger closed at $40,329,229,827,541.02 on October 14. Today it moved. The total public debt outstanding on October 15 was $40,388,317,675,071.91, an increase of $59,087,847,530.89 in one day. The number moved again overnight, and most people will never see the daily change that explains the longer trend.

Over the 64 days ending October 15, the debt grew by $474,788,355,607. That is an average pace of about $7,418,568,056 per day, or about $85,863 per second. At that average pace, debt per resident rises by about $21.64 per day. Debt per resident is a measure of scale only. It divides the total debt by the resident population so the size of the total can be compared across years. Followers get the number, every morning, in this Brief.

The daily cash picture

The Daily Treasury Statement for October 15 recorded $449,175,000,000 in deposits and $400,307,000,000 in withdrawals. Deposits are the cash coming into the Treasury General Account, mainly tax receipts and proceeds from selling Treasury securities. Withdrawals are the cash going out, mainly benefit payments, payroll, interest, and payments to contractors and states. On October 15, deposits exceeded withdrawals by $48,868,000,000, even as the debt total rose.

That pairing is the insider detail in the release. Cash in the account and total borrowing are two different measures. The cash balance can rise on a day when securities issued exceed redemptions, and the debt total follows the auction and maturity calendar. Tomorrow the Ledger will publish the next Daily Brief with the next Treasury close, and the streak of daily closes continues.

Data vintage: Treasury Debt to the Penny and Daily Treasury Statement figures dated October 15, 2026, pulled October 17, 2026. The Ledger snapshot for this date reports deposit and withdrawal totals only, so no line by line breakdown is published with this brief.

Sources and methodology

Methodology. Daily cash figures are from the U.S. Treasury’s Daily Treasury Statement (DTS) for September 28, 2026, the government’s official daily cash-flow report. The DTS records money actually moving in and out of Treasury accounts; it is not the same as the budget deficit, which is measured monthly on an accrual-adjusted basis.
