The U.S. national debt has climbed beyond $40 trillion for the first time, marking another dramatic milestone in the country’s long-running fiscal expansion.
Treasury Secretary Scott Bessent, however, is urging investors and the public not to treat the figure itself as a warning sign.
“There’s nothing magic about the $40 trillion number,” Bessent said in an interview with CNBC’s Sara Eisen on Squawk on the Street.
He argued that the size of the debt should be viewed alongside the strength and growth potential of the broader U.S. economy.
The milestone comes only five months after the national debt surpassed $39 trillion in March, highlighting the speed at which federal borrowing has continued to increase.
Bessent Says Economic Growth Can Outpace the Debt
Rather than focusing on the headline debt figure, Bessent is betting on economic expansion to improve the country’s fiscal position.
He said the administration believes the deficit is more manageable than the headline numbers suggest and pointed to what he described as fiscal consolidation during 2025.
According to Bessent, the federal deficit stood at roughly 5.7% of gross domestic product during the year.
He also argued that some factors affecting government revenues are temporary.
Among them are tariff-related refunds that increased the apparent fiscal burden but are not expected to continue at the same level.
Bessent expects tariff revenue in 2026 to remain broadly comparable with the previous year as U.S. Trade Representative Jamieson Greer works to reintroduce duties under the Section 301 process.
Treasury Defends Investment-Focused Tax Policy
Another issue at the center of Bessent’s argument is the tax treatment of business investment.
The Treasury secretary said immediate tax expensing for factories, equipment and agricultural structures should not be treated simply as government spending.
In his view, those measures encourage businesses to invest, expand production and ultimately increase the tax base.
Bessent described the policy as an investment capable of generating stronger economic activity once new factories and other projects become operational.
His broader argument is that the government can tolerate higher borrowing today if policies simultaneously generate stronger economic growth and greater future tax revenue.
Treasury Expands Bond Buybacks
The debt milestone comes as Treasury officials attempt to address concerns in the long-term government bond market.
The Treasury Department recently announced that it would at least double the maximum size of certain buyback operations, increasing them from $2 billion per operation to at least $4 billion.
The program is scheduled to begin September 9 and run through November 4, focusing on Treasury securities with maturities of 10 to 20 years and 20 to 30 years.
Those sections of the bond market have faced weak demand since late June, with some market participants describing conditions as a buyers’ strike.
Bessent indicated that the Treasury could ultimately conduct purchases larger than $4 billion per issue, suggesting officials have additional measures available if market conditions require them.
Concerns Over America’s Long-Term Financing Needs
Despite Bessent’s optimism, the government’s borrowing requirements remain a major concern for bond investors.
Treasury has increasingly relied on short-term bills to finance a deficit estimated at roughly $2 trillion a year.
Short-term borrowing has offered a lower immediate interest cost compared with longer-dated debt, particularly as 30-year Treasury yields have remained above 5%.
But that strategy also exposes the government to refinancing risks if interest rates or inflation remain elevated.
Minutes from the Treasury Borrowing Advisory Committee released earlier this month warned that the government could face a funding shortfall of approximately $1.45 trillion during fiscal years 2027 and 2028 if current auction sizes remain unchanged.
Interest Costs Are Becoming a Bigger Fiscal Burden
The rising cost of servicing federal debt is already putting pressure on the U.S. budget.
Treasury interest expenses increased by about $120 billion during the year, with annual debt-servicing costs now exceeding $1 trillion.
That figure has become particularly significant because the federal government is spending more each year on interest payments than it does on national defense.
The growing interest burden has intensified calls for Washington to address the structural gap between government spending and revenue rather than relying primarily on economic growth to solve the problem.
Bessent Promises More Spending and Revenue Measures
Bessent nevertheless said there is a strong possibility that the deficit has already reached or is approaching its worst point.
He pointed to planned cooperation with Office of Management and Budget Director Russell Vought, as well as a separate effort involving the vice president’s Fraud Task Force.
According to Bessent, those initiatives could potentially save hundreds of billions of dollars.
He also indicated that the White House could unveil a broader fiscal-consolidation strategy around the end of the week or early the following week.
The expected measures would reportedly involve both spending reductions and additional revenue initiatives.
Bond Investors Remain Unconvinced
The Treasury’s buyback announcement initially produced a strong response in the bond market.
Yields on the 30-year Treasury fell by as much as nine basis points following the announcement.
However, much of that move had reversed by the following morning, underscoring the difficulty Treasury faces in convincing investors that its measures can permanently change market sentiment.
Bessent rejected the idea that the Treasury was simply attempting to manipulate yields.
He said officials were monitoring market conditions and would determine how aggressively to act based on those conditions.
He emphasized that the government has a broad range of tools available to address liquidity problems.
Questions Over Treasury and Federal Reserve Policy
The Treasury’s strategy also intersects with the Federal Reserve’s plans under new Chair Kevin Warsh.
Market participants have been watching closely for signs that the Fed could continue reducing its balance sheet or adjust interest rates if inflation remains persistent.
Bessent said he did not view the Treasury’s buyback strategy as a constraint on the Federal Reserve and suggested that the two institutions would coordinate if there were significant changes involving the central bank’s balance sheet.
He also maintained that the Treasury’s decision to expand buybacks was not based on targeting a particular Treasury yield.
Bessent Pushes Back on Inflation Concerns
Inflation remains another major factor influencing investor confidence in U.S. assets.
Bessent acknowledged that higher oil prices, including Brent crude trading near $94 a barrel amid the continuing conflict involving Iran, have pushed headline inflation higher.
But he argued that underlying inflation pressures remain contained.
He pointed to slower wage growth in the hospitality industry, stronger income gains among the lowest-paid quarter of workers and substantial reductions in pharmaceutical prices as evidence that inflation is becoming less problematic.
Bessent said officials were not seeing significant evidence that temporary price increases were creating broader second-round inflation effects.
Labor Market Weakness Is Also Being Downplayed
The Treasury secretary also pushed back against concerns surrounding the U.S. labor market following a weaker jobs report.
He described recent employment figures as noisy and argued that stricter immigration enforcement has reduced the number of new jobs required to maintain balance in the labor market.
Bessent highlighted manufacturing and construction employment, which he said had reached their highest levels in roughly 15 years.
The comments reflect the administration’s broader effort to argue that economic activity remains stronger than some recent data might suggest.
Dollar Weakness Is Not Seen as a Crisis
Bessent similarly dismissed concerns about recent weakness in the U.S. dollar.
He argued that the size and structure of the American services economy mean the country does not respond to movements in the trade-weighted dollar in the same way as more export-dependent economies.
He described the dollar as highly stable against major trading partners such as Canada and Mexico and reiterated the administration’s commitment to maintaining a strong-dollar policy.
A Growing Debate Over America’s Fiscal Future
The dispute over the $40 trillion debt milestone ultimately comes down to competing interpretations of the same numbers.
Bessent believes stronger economic growth, increased private investment, improved tax revenues and aggressive efforts to eliminate government waste can help stabilize the nation’s finances.
Bond investors and fiscal critics remain more concerned about the structural deficit, the rising cost of interest payments and the government’s dependence on continual borrowing.
The Treasury’s expanded buyback program may help improve liquidity in parts of the bond market, but it does not eliminate the underlying need to finance a deficit approaching $2 trillion annually.
What’s Next for U.S. Debt and Treasury Policy?
The next major test will be whether the administration can translate its promised spending reductions, revenue measures and investment policies into a sustained reduction in the deficit.
At the same time, Treasury will need to manage an enormous refinancing requirement while navigating potentially volatile interest rates and inflation.
For now, Bessent’s message is clear: the $40 trillion figure itself should not determine how Americans or investors judge the economy.
His strategy rests on the belief that faster growth can eventually make today’s debt burden more manageable.
Whether financial markets accept that argument will depend less on the symbolic size of the debt and more on whether Washington can demonstrate credible progress in controlling future deficits.
Summary
The U.S. national debt has surpassed $40 trillion, but Treasury Secretary Scott Bessent argues that the milestone is not inherently alarming.
He is relying on economic growth, business investment, spending reductions and stronger revenues to improve the fiscal outlook.
At the same time, Treasury is expanding long-term bond buybacks as investors question liquidity and demand in the government debt market.
With interest costs already exceeding $1 trillion annually and borrowing needs remaining exceptionally high, the administration faces mounting pressure to show that its growth-focused approach can deliver meaningful fiscal improvement.
