The U.S. Debt Crossed $40 Trillion. Interest Is Now the Government’s Second-Largest Expense.
U.S. federal debt reached $40.047 trillion on August 18, crossing $40 trillion for the first time. The size of the number is striking. But the more important figure may be the roughly $1.1 trillion Washington is now spending on interest, a cost that has moved ahead of Medicare in the federal budget.
The key observation is that the debt is no longer just a balance-sheet number. The cost of carrying it is taking up an increasingly large part of annual federal spending.
Today’s Setup
Treasury data showed total public debt outstanding at $40.047 trillion on August 18. Of that, $32.266 trillion was debt held by the public and $7.782 trillion was held within the federal government.
Reuters reported that federal interest costs are running at roughly $1.1 trillion. Through the first 10 months of fiscal 2026, those costs surpassed Medicare spending, making interest the second-largest federal budget item behind Social Security.
The change has happened quickly. Fiscal 2025 was the first year in which debt-service costs exceeded Pentagon spending. By fiscal 2026, interest had moved above another major federal program.
What Kind of Day This Usually Is
This is a fiscal-cost repricing.
A large debt number can feel abstract because it does not have to produce an immediate market reaction. Interest expense is different. It shows how past borrowing and current rates are flowing into the government’s annual budget.
As older debt matures and is refinanced, the rate paid on that borrowing matters. When rates stay above the unusually low levels of the 2010s, carrying a large debt load becomes more expensive even without a sudden jump in borrowing.
Trump’s dollar reset exposed
You didn’t vote for this…
Something strange is happening to your money.
It wasn't voted on. It wasn't debated in the Senate. And most Americans have no idea it's even taking place but…
Not with crypto. Not with a digital currency. Something far bigger than that – and it's already been signed and sealed in the back rooms of D.C., ready to be issued by the U.S. Treasury.
Bypassing every legal and political channel under the guise of "national security," Trump has enacted this total money reset using a landmark executive order (1421).
Whether you’re a Democrat or Republican, whether you support this new money or not, it doesn't matter.
Soon, every U.S. citizen will be forced to use Trump's New Dollar to fill their gas tank, buy groceries, and pay medical bills.
Which is why I've produced a critical new documentary laying out exactly what Trump's New Dollar means for your savings, your investments, and your family's financial future.
Detailing three important steps you can take today to prepare – including the name of a core band of assets connected to Trump’s initiative that could surge as a result.
As you’ll see in my briefing, the last time America reset its money like this – under Richard Nixon’s presidency in the 1970s – it created one of the greatest wealth divides in the history of our nation.
On one side, it minted an average of 1,300 new millionaires a day for over half a century. And on the other… the folks left behind, drowning in debt, with no idea how to use America’s new money to create wealth.
As Trump rolls out his new dollar, the question is:
PS. If you’re wondering what Trump’s new money will look like, when it will be issued, what it means for your investments – all of those questions are answered in my briefing.
What Experienced Investors Watch First
One key signal is interest expense relative to federal revenue. Rising interest costs matter more when they consume a larger share of the money Washington collects.
Another signal is the yield the Treasury must pay on new and refinanced debt. The debt total changes with deficits. The cost of servicing that debt also depends on the rates attached to it.
Those two numbers help separate the size of the obligation from the strain it places on the budget.
Common Misreads
A common misread is treating $40 trillion itself as a market signal. Round numbers attract attention, but crossing one does not create a new economic condition overnight.
Another mistake is assuming the issue is simply that Washington has to “pay off” the entire debt. Governments routinely refinance maturing debt. The more immediate question is how much annual revenue must be devoted to interest while that refinancing continues.
That is where higher rates change the math.
The Playbook Lens
Focus on the carrying cost, not the headline number.
Debt matters through the claims it creates on future budgets. When interest was cheap, a growing debt load was easier to carry. When borrowing costs rise, the same debt creates a larger annual expense.
That can leave less room between federal revenue and the spending already committed to major programs, defense, emergencies, and other priorities. The constraint builds through the budget rather than arriving all at once.
Carry This Forward
The $40 trillion milestone is easy to remember. The $1.1 trillion interest bill is more useful to understand.
Large debt totals can remain large for years without producing a single dramatic moment. The carrying cost shows how that debt is affecting the federal budget in the present.
