US borrowing hits $155B a month as deficit eyes $2 trillion in FY2026

Investing.com - The U.S. Treasury is borrowing $155 billion every month in fiscal year 2026, equivalent to $39 billion per week, as the federal deficit races toward a threshold that the Committee for a Responsible Federal Budget (CRFB) projects will reach $2 trillion or more by September.

The staggering pace of borrowing is reshaping the debate over fiscal discipline, with a growing chorus of analysts and budget watchdogs arguing that traditional congressional budget processes are too slow and too politicized to address a structural imbalance of this magnitude — and that artificial intelligence-assisted tools may offer a faster path to identifying redundancies and projecting fiscal scenarios.

According to the CRFB, citing the Congressional Budget Office's latest Monthly Budget Review, the U.S. borrowed $1.4 trillion in the first nine months of FY2026, including $126 billion in June alone. That figure already exceeds the comparable nine-month total for FY2025 by $35 billion, underscoring how quickly the trajectory is deteriorating even as the broader economy continues to expand.

Perhaps the most striking symptom of the imbalance is the interest bill. Net interest payments on the public debt have reached $857 billion through the first nine months of the fiscal year, or roughly $23.8 billion per week, according to Fortune citing CBO data. To put that in context, interest payments now exceed the combined outlays of the Departments of Defense, Commerce, Homeland Security, Education, the EPA, the Small Business Administration, and the U.S. Postal Service.

"We will likely borrow $2 trillion or more this fiscal year — an astounding figure given that the economy keeps growing and unemployment is low," said Maya MacGuineas, president of the CRFB. "This is likely the tip of the iceberg; borrowing will soar if policymakers fail to get our entitlements under control."

The national debt itself stood at approximately $39.4 trillion as of July 10, on a pace that analysts warn could see it double within three decades. Debt-to-GDP has reached levels not seen since World War II, according to Yahoo Finance, even as the economy grows at roughly 2.1% annually. The concern among fiscal hawks is that the country is exhausting its shock-absorber capacity before a recession has even arrived, leaving policymakers with fewer conventional tools should growth stall.

Financial markets are already pricing in the cost of sustaining that debt load. The 10-year Treasury note auctioned on July 8 cleared at a yield of 4.58%, up from 4.538% at the prior auction, while the 30-year bond auction on July 9 cleared at 5.058%, reflecting investors' demand for higher compensation to absorb an expanding supply of government paper.

MacGuineas framed the political challenge starkly: "Policymakers should instead be targeting a much more sustainable deficit at 3% of GDP, putting together a bipartisan commission to address our fiscal situation and entitlements, and perhaps most importantly, being honest with the public about the grave dangers we face by remaining on this unsustainable path."

Proponents of AI-assisted budgeting argue that large-language and optimization models could flag fraud, surface spending redundancies, and simulate fiscal scenarios far faster than traditional budget cycles allow. Internationally, South Korea cited revenues from the AI chip boom to fund a record 2027 national budget exceeding $530 billion, illustrating that technology-driven revenue uplift is becoming part of the sovereign fiscal equation as well.

The immediate catalyst for pressure on rates and risk sentiment arrives Tuesday, July 14, when the Bureau of Labor Statistics releases June CPI data. Consensus forecasts point to a month-over-month reading of -0.1%, a sharp reversal from May's +0.5%, with core CPI expected at +0.2%. A softer inflation print would ease some pressure on the Fed's rate path, potentially lowering future debt-servicing costs at the margin. The following day, June PPI data is due, providing a read on upstream price pressures that feed into indexed entitlement costs, the very programs that MacGuineas warns are the long-run driver of the deficit spiral.

With Social Security and Medicare trust funds projected to face exhaustion within seven years, the arithmetic is unforgiving. Monthly borrowing that averages $155 billion in a growing economy leaves the U.S. with vanishingly little fiscal room if conditions deteriorate, and no clear political consensus, yet, on how to close the gap.
