America’s $38 Trillion National Debt Is Driving Over $1 Trillion a Year in Interest Costs, CRFB Warns

4 min read




The United States has crossed a financial threshold that economists and fiscal watchdogs have warned about for decades. According to the Committee for a Responsible Federal Budget (CRFB), the nation’s $38 trillion national debt is now responsible for more than $1 trillion in annual interest payments—and those costs are expected to remain above that level going forward.
The milestone signals a profound shift in federal finances, one that could reshape government priorities, crowd out public spending, and increase long-term economic risk.
Interest Payments: The Fastest-Growing Federal Expense
Interest on the national debt has quietly become one of the largest and fastest-growing line items in the federal budget. Unlike discretionary spending—such as infrastructure, defense, or education—interest payments are mandatory. The government has no choice but to pay them.
CRFB notes that rising interest rates combined with historically high debt levels have created a compounding effect:

Higher debt means more interest owed
Higher rates mean each dollar of debt is more expensive
Refinancing older, low-rate debt increases overall costs

The result is a structural increase in interest spending that shows no sign of reversing under current policies.
Why the $38 Trillion Debt Matters Now
For years, critics of deficit spending were told that debt was manageable as long as interest rates remained low. That era is over.
With Treasury yields significantly higher than during the 2010s, the federal government is now paying far more to borrow money, even for routine operations. CRFB warns that interest costs could soon rival or exceed spending on:

National defense
Medicaid
All discretionary domestic programs combined

This marks a fundamental change in how federal resources are allocated.
What’s Driving the Debt Explosion?
CRFB points to several overlapping forces behind the surge in national debt:
1. Chronic Budget Deficits
The U.S. has run persistent deficits for decades, spending more than it collects in revenue almost every year.
2. Pandemic-Era Spending
Emergency stimulus programs added trillions to the debt in a short period, accelerating long-term fiscal pressures.
3. Aging Population
Rising costs for Social Security, Medicare, and other entitlement programs are increasing baseline spending.
4. Higher Interest Rates
As older debt matures, it is replaced with new debt at higher rates, locking in larger interest obligations.
The $1 Trillion Problem: Why It’s So Concerning
Paying over $1 trillion annually in interest has serious implications:

Crowding out priorities: Money spent on interest cannot be spent on healthcare, infrastructure, climate policy, or defense
Reduced fiscal flexibility: The government has less room to respond to recessions or emergencies
Higher future taxes or borrowing: Interest costs themselves are often financed with more debt
Increased risk of a debt spiral: Borrowing to pay interest compounds the problem over time

CRFB emphasizes that interest payments provide no public services, no economic investment, and no social benefit—they simply service past borrowing.
Is the U.S. at Risk of a Debt Crisis?
While the United States benefits from issuing the world’s reserve currency, CRFB cautions against complacency. Investors may tolerate high debt for long periods, but confidence can erode quickly if fiscal discipline appears absent.
Potential risks include:

Rising borrowing costs due to investor concerns
Reduced demand for U.S. Treasury securities
Pressure on the dollar’s global role
Greater vulnerability during economic downturns

The danger, CRFB argues, is not an immediate collapse but a slow erosion of economic strength.
What CRFB Says Needs to Change
The Committee for a Responsible Federal Budget has repeatedly called for bipartisan action, including:

Gradual deficit reduction
Tax reforms that increase revenue
Adjustments to entitlement programs to reflect demographic realities
Policies that stabilize debt relative to GDP

CRFB stresses that delaying action only increases the eventual cost, as higher debt leads directly to higher interest payments.
The Political Reality
Despite growing concern from fiscal experts, meaningful reform remains politically difficult. Cutting spending or raising taxes carries electoral risk, and short-term priorities often override long-term sustainability.
As a result, interest payments are on track to consume a larger share of the federal budget each year—without a clear plan to stop the trend.
The Bottom Line
The U.S. national debt reaching $38 trillion is no longer an abstract figure. Its consequences are already visible in the form of over $1 trillion in annual interest payments, a burden that CRFB warns will persist unless policymakers act.
The longer the issue is ignored, the more federal resources will be devoted to servicing past decisions rather than investing in the country’s future. In fiscal terms, America is increasingly paying yesterday’s bills with tomorrow’s money—and the interest tab is only getting larger.
