Nearly a Fifth of Every Dollar Washington Collects Now Goes to Interest

The federal debt passed forty trillion dollars in August and did not pause. Treasury’s own daily ledger put it at $40.1 trillion on September 3. But the total has stopped being the most useful number. What matters now is what it costs to carry, and by an analysis from the investment firm DoubleLine, net interest reached 18.5 percent of federal revenue in 2025, edging past the record set in 1991.

Nineteen cents of every dollar Washington collects now services borrowing already done. It builds nothing, staffs nothing, and pays no one a benefit. It has passed defense in the federal budget, which is to say Washington now spends more renting its own past than it spends fielding an army.

The direction is not in dispute. The 1991 record was set when the debt was a fraction of the economy it now exceeds. The Congressional Budget Office projects interest climbing toward a quarter of federal revenue within a decade. Treasury’s own auditors describe the path in a single word, unsustainable, and Moody’s, Fitch, and Standard and Poor’s have each pulled the United States below its top credit rating.

Texans pay a measured share of it. “Can Texas Make It?”, the movement’s assessment of what independence would cost and what Texans already pay, put Texas’s portion of federal net interest at roughly $80 billion in fiscal 2025, up from about $31 billion in 2019. That is not a separate Texas tax bill. It is the slice of Washington’s interest payment that Texans cover, and it buys them nothing whatsoever.

None of this is the work of one administration, and hanging it on one is how the problem keeps outliving elections. The borrowing was bipartisan and it ran for decades. Most of the people who authorized it are gone from office. The permanent establishment that runs Washington between elections is not gone, and it has never once been made to answer for the bill it runs up in Texas’s name.

Texans did not vote for this ledger and cannot vote it away from the inside. Administrations of both parties have arrived promising to rein it in, and the figure has risen through every one of them. The argument for remaining in the union was always, at bottom, a financial argument. It gets weaker every quarter, and the remedy that actually reaches it is a question Texans have not yet been asked.
