The total debt of the United States government has crossed $40 trillion for the first time. Treasury Department data showed total public debt outstanding at $40.047 trillion in its daily statement, a milestone reached sooner than official forecasters had expected.
What the number includes
The headline figure combines two kinds of borrowing:
- Debt held by the public: $32.266 trillion — Treasury bills, notes and bonds owned by investors, companies, foreign governments and the Federal Reserve.
- Intragovernmental holdings: $7.782 trillion — money the government owes to its own trust funds, such as Social Security.
Economists usually focus on debt held by the public, because that is what must be financed in markets and what drives interest costs.
Faster than forecast
The debt has more than doubled in less than a decade. It stood at $19.95 trillion in January 2017, at the start of Donald Trump’s first term. The Congressional Budget Office (CBO) had projected that total borrowing would reach about $39.6 trillion only by the end of fiscal year 2026, so the government has run ahead of that path.
The CBO also says the US is approaching its statutory debt limit of $41.1 trillion, and it projects total debt rising to about $64 trillion by 2036 under current policies.
Why it keeps rising
There is no single cause. Heavy spending under both the Trump and Biden administrations, rising costs for safety-net programmes, tax cuts that have held back revenue and — increasingly — interest payments on existing debt have all contributed. Because interest is itself paid with borrowed money when the budget is in deficit, higher rates create a compounding effect.
That last factor has become more pressing as interest rates have stayed high: every maturing bond the Treasury refinances at today’s yields adds to the government’s annual interest bill.
Why it matters for households
A large and growing debt does not mean the US is about to default; the government borrows in its own currency and Treasuries remain the world’s benchmark safe asset. But economists point to several practical effects:
- Interest crowding out other spending: more of each budget dollar goes to bondholders rather than programmes.
- Higher borrowing costs: heavy federal borrowing can push up yields that feed into mortgages and business loans.
- Less room in a crisis: a high starting debt can limit how forcefully the government can respond to a recession or emergency.
What to watch next
The approaching debt ceiling sets up another political fight in Congress, and fiscal policy is likely to feature in campaigns ahead of the November midterm elections. Investors will also watch Treasury auctions closely for signs of weaker demand, which would show up as higher yields.
