US debt has hit $40tn – Will that be a wake-up call?
US national debt has surpassed $40tn, raising significant concerns domestically and internationally. This milestone, driven by increased public spending and higher interest rates, signals growing economic challenges.

The US national debt has doubled in the last decade, reaching $40tn, a figure that took nearly 200 years to hit $1tn. This surge is attributed to public spending under multiple administrations, responses to crises, and rising interest rates, leading economists to warn of a 'flashing yellow light' for the world's largest economy.
Imagine your family has a piggy bank, but instead of saving, you keep borrowing money to buy things, and now you owe a huge amount, like $40 trillion! The grown-ups who lend you money are starting to worry, so they want more money back when you pay them. This means it costs your family even more just to pay off the interest, leaving less money for other important things. If this keeps going, it could make everything from buying a house to getting a car loan more expensive for everyone.
Analysis
The recent milestone of the US national debt reaching $40tn serves as a stark indicator of mounting fiscal pressures. This figure, which has doubled in just a decade, is a culmination of sustained public spending increases under both the Donald Trump and Joe Biden administrations, coupled with significant outlays during crises like the 2008 financial crisis and the Covid pandemic. Revenues have simultaneously been undermined by tax cuts, exacerbating the imbalance. The sheer scale of this debt, now rising by approximately $90,000 every second, or $7.8bn daily, according to the Congress Joint Economic Committee, highlights a trajectory that many economists deem unsustainable without intervention.
40tn
The $40tn debt figure is not merely a symbolic number; it represents a tangible burden on the US economy and its future. Interest payments on this debt are now 15% higher than the previous year and consume almost 20% of tax revenue, surpassing even defense spending. This escalating cost of servicing the debt diverts funds that could otherwise be invested in public services or economic growth initiatives. While the US benefits from its status as the world's largest economy and the dollar's role as the global reserve currency, offering a longer 'runway' for fiscal indiscretion, this advantage is not infinite. The current trajectory suggests that without significant policy changes, the debt is forecast to climb to about $64tn by 2036, pushing the nation closer to a critical financial threshold.
Eric Swanson
Eric Swanson, a professor of economics at the University of California and former senior economist at the Federal Reserve, emphasizes the critical role of interest rates in the current debt crisis. He notes that long-term interest rates in the US are at multi-decade highs, driven partly by inflation concerns and partly by the extreme levels of government borrowing. This environment creates a 'vicious cycle' where the bond market demands higher returns to compensate for the perceived risk of lending to the US government. Investors are increasingly wary, and the government must offer ever-higher returns to attract buyers for its bonds. This competition for capital is further intensified by tech firms borrowing substantial sums for AI development, drawing away investor cash that might otherwise go to government bonds. The consequence is that the funding of the deficit becomes progressively more expensive, placing additional strain on the federal budget.
Mohamed A El-Erian
Mohamed A El-Erian, a professor at the Wharton School, likens the current situation to a 'flashing yellow light,' indicating caution rather than immediate catastrophe, but stressing the urgency of addressing the issue. He points out that while the US debt-to-economy ratio of 126% is lower than some G7 nations like Japan and Italy, the diminishing investor appetite for US government bonds is a significant concern. El-Erian also highlights the global ramifications, stating that 'what happens in the US never stays in the US,' meaning higher US borrowing costs inevitably spill over, raising costs for other countries as well. For ordinary households, this translates into higher rates for mortgages, auto loans, and credit cards, with lower-income individuals being disproportionately affected. Firms also pass on their increased borrowing costs through higher prices, ensuring the debt's impact 'finds its way to the pocketbooks of people one way or another.' While economic growth could ease the problem by generating more tax revenue, without sufficient growth, the US may face difficult choices regarding tax reform, public spending cuts, or even debt restructuring.
Key points
- US national debt has reached $40tn, doubling in the last decade due to increased public spending and higher interest rates.
- Interest payments on the national debt are now 15% higher than last year and consume nearly 20% of tax revenue, exceeding defense spending.
- Economists warn of a 'flashing yellow light' as long-term interest rates are at multi-decade highs, driven by inflation and extreme government borrowing.
- Investor appetite for US government bonds is diminishing, forcing the government to offer higher returns, which in turn raises borrowing costs globally.
- Households are likely to face higher rates for mortgages, auto loans, and credit cards, with lower-income individuals being hit hardest.
Despite the current concerns, economists suggest that robust economic growth could significantly ease the debt problem by generating more tax revenue. This increased income would help cover government spending and interest payments, potentially stabilizing the fiscal situation without requiring drastic austerity measures.
The escalating debt could lead to a 'vicious cycle' where diminishing investor appetite forces the US government to offer ever-higher returns on its bonds, driving up borrowing costs for everyone. This could result in higher interest rates for mortgages and loans, increased prices for consumers, and potentially trigger financial market turmoil if investor confidence erodes further.
