U.S. Debt Crosses $40 Trillion as Borrowing Costs Rise

WASHINGTON — The United States has reached a major fiscal milestone, with total federal debt surpassing $40 trillion as investors increasingly focus on the country's borrowing needs and long-term budget outlook.

The milestone comes amid a sharp rise in long-term Treasury yields. The 30-year Treasury yield recently reached its highest level since 2007, increasing borrowing costs for the government while also affecting businesses, consumers and financial markets.

In response to pressure in the bond market, the U.S. Treasury announced that it would double the size of some buyback operations for long-dated government debt to $4 billion per operation.

The intervention helped push Treasury yields lower, although analysts noted that buying back long-term bonds does not reduce the underlying federal deficit.

The debt milestone arrives as markets also contend with higher oil prices, inflation concerns and geopolitical uncertainty, adding further pressure to the U.S. economic outlook.

The $40 trillion threshold puts America's debt trajectory back at the center of financial and political debate, with higher interest costs creating an increasingly important challenge for the federal budget.
