The total federal debt reached $40,528,358,939,415.85 on October 26, 2026, the first daily reading above $40.5 trillion in the Treasury Department’s Debt to the Penny series. The balance rose $65.21 billion from the prior business day, when it stood at $40,463,151,897,249.19. The crossing lands two days before the Federal Open Market Committee closes its October 27 and 28 meeting, a decision that sets the policy rate feeding into the current prime rate and into the yields Treasury pays on new issuance.
How the jump was built matters as much as the headline figure. Intragovernmental holdings, the securities federal trust funds own, rose $40.56 billion. Debt held by the public, the portion sold into markets, rose $24.65 billion to $32,635,294,814,294.48. Month to date the total has climbed $356.53 billion from the September 30 fiscal year close of $40,171,825,101,340.31. Against the same date a year ago, when the total stood at $38,076,934,220,531.56, the debt has grown $2.45 trillion. That growth is running while Treasury refinances maturing securities at the steepest coupons in two decades, a combination the Congressional Budget Office measured in an October 8 study of interest rate risk to the federal budget.

What the October 26 Reading Shows
Treasury publishes the total public debt outstanding each business day in its Debt to the Penny series, drawn from the Daily Treasury Statement. The October 26 entry of $40,528,358,939,415.85 is the first in that series above $40.5 trillion. The balance read $40.30 trillion on October 9 and $40.39 trillion on October 16, so the $40.5 trillion threshold fell 17 days after the $40.3 trillion mark. The Bureau of the Fiscal Service posts each figure with a one business day lag, which is why the October 26 reading published on October 27. The series carries no estimate and no revision schedule. It records the par value of outstanding securities at the close of business.
The $65.21 billion increase from October 23 is the largest single print rise since October 1, when the total jumped $88.8 billion on the first day of fiscal 2027. Five of October’s prints have risen by more than $40 billion and five have shown outright declines, which happens when Treasury draws down its cash balance instead of issuing. Because the October 26 figure follows a Friday close, it absorbs three calendar days of settlement activity, including coupon securities from the week Treasury sold $213 billion of notes. Settlement dates, not daily deficits, drive most of the variation in the series. The trend underneath is steadier: the total has risen in 12 of October’s 17 business day prints.
Where the $65 Billion Came From
Debt to the Penny splits the total into two components. Debt held by the public covers bills, notes, bonds, TIPS and floating rate notes sold to investors, foreign central banks and the Federal Reserve. Intragovernmental holdings cover non marketable securities issued to federal trust funds, chiefly Social Security, Medicare and federal retirement accounts, which by law invest their surpluses in Treasury paper. On October 26 the public component rose $24.65 billion to $32,635,294,814,294.48 while intragovernmental holdings rose $40.56 billion to $7,893,064,125,121.37.
That split runs against the monthly pattern. Across October the public component accounts for $210.3 billion of the $356.53 billion gain, with trust funds supplying the other $146.3 billion. Trust fund balances move on their own calendar: Social Security credits payroll tax receipts and redeems securities to cover benefit payments, and the end of October concentrates both flows. Intragovernmental debt is an obligation the government owes itself, so it does not compete with private borrowers for capital and carries no market yield. It still counts toward the statutory debt limit and toward the $40.5 trillion total. For borrowing costs, the public component is the one that bites. It cleared $32.5 trillion for the first time this month and now sits near annual gross domestic product, which CBO put at 100.6% for 2026.
What the Debt Costs at Current Yields
The average interest rate across all marketable Treasury securities was 3.518% as of September 30, 2026, according to Treasury’s Average Interest Rates on U.S. Treasury Securities dataset. That average sits far below current market yields. The 10 year Treasury closed at 5.00% on October 26, the 30 year at 5.31% and the 2 year at 4.68%, per the constant maturity series carried in FRED. Every bill, note and bond that matures is refinanced at those levels, so the average rate on the outstanding stock keeps climbing even in a month with no new deficit spending at all.
CBO measured that exposure on October 8 in Projections of Deficits and Debt Under Two Scenarios With Higher Interest Rates. Under its baseline, debt held by the public rises from 100.6% of gross domestic product in 2026 to 120.2% in 2036. If rates run 150 basis points above baseline, the share reaches 133.1% of GDP in 2036, net interest costs run $4.9 trillion higher across 2026 through 2036, debt service adds $1.1 trillion more, and cumulative deficits widen by $6.0 trillion. A milder 50 basis point overshoot still adds $1.6 trillion in net interest and $297 billion in debt service. CBO’s February outlook had already placed net interest above $1.0 trillion in 2026, or 3.3% of GDP, rising to 4.6% by 2036.
What Changes for Your Money
Federal borrowing does not set household rates directly, but it works through the same yield curve that prices consumer credit. The bank prime loan rate stood at 7.00% in the Federal Reserve’s H.15 release of October 26, with the effective federal funds rate at 3.88%. Prime moves in step with the Fed’s target range, and most variable rate products are quoted as prime plus a margin. Credit card APRs, home equity lines and many small business lines reprice within one or two billing cycles of a prime change. Our guide to how Fed decisions reach consumer loans traces that path step by step.
Fixed rate products key off the long end of the curve rather than off prime. Thirty year mortgage pricing tracks the 10 year Treasury yield plus a spread, so the 5.00% close on October 26 is the input that matters for anyone shopping current mortgage rates. Heavy Treasury issuance tends to lift that yield by adding supply, which is how debt growth reaches a mortgage borrower even though the Fed never votes on it. Savers sit on the other side of the same trade. Elevated bill yields keep deposit competition alive, and the best high yield savings accounts and best CD rates both price off short Treasury yields that Wednesday’s decision will move.
Treasury posts Debt to the Penny every business day for the prior day, so you can read the official number yourself instead of trusting a ticker widget. If you carry variable rate debt, the figure to watch this week is not the debt total but the Fed’s target range, announced at 2:00 p.m. ET on October 28. Prime follows the target range within a business day. Fixed rate shoppers should track the 10 year Treasury yield instead, since it moves on auction results and inflation prints all month.
Frequently Asked Questions
How much is the US national debt right now?
The total federal debt was $40,528,358,939,415.85 on October 26, 2026, the first Treasury reading above $40.5 trillion. Of that total, $32.64 trillion is debt held by the public and $7.89 trillion is intragovernmental holdings owed to federal trust funds. The balance rose $65.21 billion from the prior business day.
Who owns most of the US debt?
The largest single holder is the federal government itself. Intragovernmental holdings, the securities issued to trust funds such as Social Security and Medicare, totaled $7.89 trillion on October 26, roughly 19% of the $40.53 trillion total. The remaining $32.64 trillion is debt held by the public, a category that spans domestic banks, pension funds, mutual funds, state and local governments, the Federal Reserve and foreign official institutions. No single foreign holder comes close to the trust funds in size.
Is the US debt clock accurate?
Online debt clocks interpolate between official readings, so they display a number ticking every second while the official figure changes once per business day. The authoritative source is Treasury’s Debt to the Penny series, published by the Bureau of the Fiscal Service with a one business day lag. It reports the par value of outstanding securities at the close of business, not a projection. A clock can run ahead of or behind the official total by tens of billions of dollars between prints.
Does the national debt raise my credit card interest rate?
Not directly. Card APRs are tied to the bank prime loan rate, which tracks the Federal Reserve’s target range for the federal funds rate. Prime was 7.00% in the H.15 release of October 26. Federal borrowing reaches consumer rates one step removed, by adding Treasury supply that lifts yields across the curve and by raising the interest bill that shapes later fiscal and monetary conditions. A rising debt total on its own will not reprice your card in the next billing cycle.
What happens to rates if the Fed moves on October 28?
A change in the target range reaches the prime rate within a business day, and variable rate products follow over the next one or two billing cycles. The effective federal funds rate was 3.88% and prime was 7.00% in the October 26 H.15 release. A 25 basis point increase would put prime at 7.25% and lift card APRs, home equity lines and many business credit lines by the same amount. Fixed mortgage and auto rates would move only to the degree the 10 year yield reacts.
How fast is the national debt growing?
The total has risen $356.53 billion since the fiscal year closed at $40,171,825,101,340.31 on September 30, 2026, about $21 billion for each of October’s 17 business day prints. Measured against October 28, 2025, when the total stood at $38,076,934,220,531.56, the debt has grown $2.45 trillion in a year. Fiscal 2026 as a whole added $2.53 trillion, up from the $37,637,553,494,935.61 recorded at the close of fiscal 2025.
