United States national debt has reached a record $40 trillion, pushing borrowing costs higher on jittery bond markets after a White House intervention failed to calm investor concerns.
Borrowing costs rose again on Wednesday after the soothing effect of a federal move to inject billions of dollars into the market proved short-lived. The benchmark figure, which has doubled in less than a decade, has deepened concerns among financial traders about public finances in the world largest economy while the conflict in Iran drives oil prices higher and amplifies inflationary pressures.
US Treasury bonds represent government debt securities issued by the Treasury Department to fund federal operations. Yields on these bonds act as a primary benchmark for borrowing rates throughout the global financial system, influencing everything from corporate loan rates to consumer home mortgages.
Bond market reactions and Treasury yields
A sharp rout in global bond markets earlier this week saw yields on US Treasury securities and other major sovereign debt soar. The sell-off was temporarily halted after Treasury Secretary Scott Bessent announced that the government would double its planned buybacks of US bonds.
Yields on 30-year US Treasury bonds, which reached a 19-year high of 5.34 per cent on Tuesday, initially fell back to 5.18 per cent following the announcement. However, yields rose again on Wednesday to approach 5.27 per cent as market anxiety resurfaced.
Alongside the pressure on bonds, the US dollar fell to a three-month low. Market analyst Mohit Kumar, an economist at Jefferies, suggested that the Trump administration intervened primarily because of the risk that rising Treasury yields pose to American mortgage borrowers. Analysts at JP Morgan noted, however, that borrowing costs will continue to climb unless the White House directly addresses the country rising debt load.
Surging national debt and long-term fiscal warnings
Data released by the US Treasury confirmed that total debt now stands at $40 trillion. The national debt has more than doubled since Donald Trump first assumed the presidency in January 2017, when the total was $20 trillion. Fiscal experts attribute the accumulation to pandemic-era emergency spending, major infrastructure legislation, and tax cuts, combined with an ongoing gap between federal tax receipts and government expenditure.
America debt currently equals approximately 120 per cent of its gross domestic product, the total value of goods and services produced by the economy. Servicing the interest on this debt costs the federal government roughly $1.1 trillion each year.
Independent watchdogs in Washington have warned that the nation faces a potential debt crisis unless lawmakers agree to raise taxes, reduce government spending, or combine both measures. Maya MacGuineas, president of the bipartisan Committee for a Responsible Federal Budget, noted that the debt has quadrupled in less than two decades after taking until 1981 to reach its first $1 trillion.
MacGuineas described the trend as staggering, adding: "It is staggering how predictable the fiscal decline of a global power can become."
Financial experts also warned that temporary market measures would not fix structural deficits. Susannah Streeter, chief investment strategist at Wealth Club, said the buyback announcement by Bessent "could prove to be a sticking plaster which could be rapidly ripped off." She added: "It does not change the fundamental picture of rising government debt, persistent deficits and inflationary pressures."
Global market spillovers and British gilt pressures
Addressing international markets, the turmoil in US debt has reverberated across global markets. In the United Kingdom, yields on 30-year British government bonds, known as gilts, reached 5.86 per cent earlier in the week, nearing a 28-year high, before trading close to 5.84 per cent on Wednesday.
Official data showed UK government debt reached £2.9 trillion in June, with July figures scheduled for release on Thursday. Gilt investors remain concerned about how the British government will fund its commitments, including a major council housebuilding push, social care reform, and increased spending on national defence.
