The United States national debt has reached a record $40 trillion, contributing to increased volatility in bond markets. Borrowing costs saw a temporary decline after the Treasury announced an expansion of bond buybacks but have since begun to rise again.
The $40 trillion figure represents a doubling of the national debt in less than a decade. This staggering increase has heightened concerns among traders regarding the fiscal health of the U.S. economy, particularly as geopolitical events like the Iran war influence oil prices and inflationary pressures.
Yields on U.S. 30-year Treasury bonds, which had reached a 19-year high of 5.34 percent earlier in the week, briefly fell to 5.18 percent following Treasury Secretary Scott Bessent's announcement. However, yields edged back up to approximately 5.27 percent. The dollar also reached a three-month low, and disruptions in the U.S. Treasury market have been mirrored in global bond markets, with yields on U.K. 30-year bonds nearing a 28-year high.
Analysts suggest the Treasury's intervention may have been influenced by the potential impact of rising yields on mortgage borrowers. However, economists from J.P. Morgan have stated that borrowing costs will persist unless the U.S. addresses its national debt.
The national debt has more than doubled since January 2017, when it stood at $20 trillion. Contributing factors include pandemic-era spending, infrastructure investments, tax cuts, and the ongoing deficit between government spending and revenue. Watchdog groups have warned of a potential debt crisis if legislative measures, such as increased taxes or reduced spending, are not implemented.
According to the bipartisan Committee for a Responsible Federal Budget, the $40 trillion debt figure has quadrupled in less than 20 years, a stark contrast to the time it took to reach $1 trillion, which was 1981. The U.S. debt currently stands at approximately 120 percent of its gross domestic product, with annual spending on debt interest exceeding $1.1 trillion.
Susannah Streeter, chief investment strategist at Wealth Club, commented that the Treasury's intervention might only offer a short-term solution. She noted that it does not alter the fundamental issues of rising government debt, persistent deficits, and inflationary pressures. In comparison, the U.K.'s national debt stood at £2.9 trillion in June, with investors also expressing concern over government spending plans for housing, social care, and defense.
