Summary
The U.S. government has borrowed about $155 billion every month in the current fiscal year, pushing the national debt to $39.4 trillion. As a result, the Treasury is now paying roughly $24 billion each week just in interest on that debt. This growing cost is raising alarms among budget experts who warn that the country's spending path is not sustainable.
Main Impact
The federal deficit for the first nine months of fiscal year 2026 has reached nearly $1.4 trillion. That is already higher than the $1.3 trillion borrowed during the same period last year. The biggest driver of this increase is the cost of interest payments, which have jumped to $857 billion so far this year. That is about $100 billion more than last year, mainly because the total debt is larger and long-term interest rates are higher.
Key Details
What Happened
The U.S. Treasury has been borrowing heavily every month since October 2025. The monthly borrowing now averages $155 billion, or about $39 billion per week. This borrowing has pushed the national debt to $39.4 trillion, a record high. The interest on that debt is now costing taxpayers $23.8 billion per week.
Important Numbers and Facts
Interest payments on the debt are now larger than the combined spending of several major government departments. These include the Departments of Defense, Commerce, Homeland Security, Education, the Environmental Protection Agency, and the Small Business Administration. In addition, spending on Social Security rose by $62 billion (5%), Medicare by $58 billion (8%), and Medicaid by $49 billion (10%) compared to last year.
Background and Context
The U.S. government has been running large deficits for years, meaning it spends more than it collects in taxes. This has caused the national debt to grow steadily under both Republican and Democratic administrations. The rising cost of interest payments is a direct result of that growing debt. At the same time, the U.S. population is aging, which increases demand for programs like Social Security and Medicare. The median age in the U.S. rose from 39.2 in 2024 to 39.4 in 2025, and the number of older Americans is growing.
Public or Industry Reaction
Budget watchdogs are sounding the alarm. The Committee for a Responsible Federal Budget, a group that has long pushed for lower borrowing, says the current situation is "likely the tip of the iceberg." Maya MacGuineas, the group's president, warned that the government will likely borrow $2 trillion or more this fiscal year. She called that figure "astounding" because the economy is still growing and unemployment is low. MacGuineas urged policymakers to cut spending and increase revenues, and to be honest with the public about the risks of the current path.
What This Means Going Forward
If borrowing continues at this pace, interest costs will keep rising. That means less money for other priorities like defense, education, or infrastructure. The CBO warns that Social Security and Medicare trust funds could run out within seven years, which would force automatic cuts to benefits. Some experts suggest targeting a deficit of 3% of the economy, which is about half the current level. But so far, there has been little action from policymakers to address the issue.
Final Take
The U.S. government is borrowing more than ever, and the cost of that borrowing is growing fast. With an aging population and rising spending on social programs, the pressure on the budget will only increase. Without changes to spending or tax policy, the national debt and its interest costs will continue to climb, leaving less room for other government priorities.
Frequently Asked Questions
Why is the U.S. government borrowing so much money?
The government borrows money because it spends more than it collects in taxes. This is called a deficit. The deficit has grown due to higher spending on programs like Social Security, Medicare, and interest payments on the existing debt.
How much interest does the U.S. pay on its debt each week?
The U.S. Treasury is now paying about $24 billion per week in interest on the national debt. That adds up to roughly $857 billion so far this fiscal year.
What happens if the national debt keeps growing?
If the debt keeps growing, interest payments will take up a larger share of the federal budget. That could mean less money for other programs like defense, education, and infrastructure. It could also lead to higher taxes or cuts to popular programs like Social Security and Medicare.
