The Joint Economic Committee’s latest monthly update puts the mechanics of federal borrowing in terms that resist abstraction: gross national debt has grown by $2.67 trillion over the past year, a pace of $85,111.72 every second. That translates to $117,279 for every American and $297,522 per household, up $7,806 and nearly $20,000 respectively from the same period a year ago. The figures, compiled by committee chairman David Schweikert, make the debt’s acceleration measurable in minutes rather than fiscal years.
The per-second arithmetic
At the current three-year average daily growth rate of $7.35 billion, $306.4 million per hour, $5.11 million per minute, the $40 trillion threshold crossed last month would give way to $41 trillion by mid-January. Another trillion would follow 151 days later, around June 2027. The five-year increase stands at $11.68 trillion. The committee’s projection assumes the recent trajectory holds; it does not incorporate any policy change or economic shock.
The household bill that never arrives
Michael Peterson, chairman of the Peterson Foundation, has argued that the absence of a direct invoice does not mean the public escapes the cost. When the government borrows at this scale, he told Fortune last month, it pushes up interest rates across mortgages, auto loans and credit cards, while also feeding broader inflation. Households pay through higher expenses and, eventually, through the taxes required to service the debt. The per-household figure of $297,522 is a stock measure, not an annual flow, but the year-over-year increase of roughly $20,000 illustrates how quickly the implicit liability is compounding.
The interest math
The Treasury’s own borrowing cost has risen in step. The average interest rate on total marketable debt reached 3.475% in August 2026, up from 3.415% a year earlier and more than double the 1.458% recorded five years ago. Over the past 12 months, interest paid to trust funds totaled $294.76 billion, averaging $24.56 billion a month. Recent Treasury buybacks have attempted to stabilize the market, but the elevated rate level persists, widening the gap between new issuance and the low-coupon debt it replaces.
What the bulls say
Defenders of the current trajectory note that repeated warnings of a market crisis have not materialized. Longer-dated Treasury yields remain elevated, but analysts attribute the move to factors outside debt sustainability concerns. The argument rests on the United States’ unique position as issuer of the world’s reserve currency and the absence, so far, of a funding disruption. The JEC’s numbers do not settle that debate; they only quantify the pace at which the bet is being tested.
