US debt surpasses $40 trillion

The U.S. government's debt has crossed the symbolic threshold of $40 trillion for the first time, according to data released Wednesday by the Treasury Department. This milestone occurs as borrowing costs continue to climb.

Following the latest bond issuance on Tuesday, the U.S. Treasury debt reached $40.047 trillion. This increase is attributed to higher borrowing for health and social security programs, as well as escalating interest payments. The debt's growth has been faster than anticipated, with the Congressional Budget Office (CBO) previously projecting federal debt to be around $39.4 trillion by year-end.

This development comes amid concerns over inflation, particularly with the Middle East conflict and soaring energy prices pushing borrowing costs to levels not seen in years. The yield on long-term U.S. Treasury bonds (30-year) hit its highest level since 2007 on Tuesday. This forces the government to spend more to refinance, thereby worsening its debt situation.

In response, the Treasury Department announced on Wednesday plans for larger long-term bond buybacks starting in September, a move that provided some reassurance to investors and eased rates. "It is well known that the federal government has an unsustainable deficit rate," noted Jessica Riedl, a budget specialist at the Brookings Institution. The nation's debt has more than doubled since the 2008 financial crisis, now representing nearly 125% of U.S. gross domestic product (GDP). Riedl highlighted that deficit levels, once concerning at 3% to 4% of GDP, are now approaching 6% to 7% of GDP, making markets more nervous.
