Question
US national debt crosses $40T with annual interest expense reaching $1.25T
Direct answer
U.S. sovereign debt has reached $40 trillion, accompanied by net interest expense rising to $1.25 trillion per year. The compounding servicing load increases mandatory budget outlays and sustains heavy Treasury coupon issuance across primary dealer auctions. Value investor Howard Marks noted that while panic-driven allocation changes are historically counterproductive, sustained debt expansion reinforces the need for balance sheet quality, international revenue exposure, and robust operating margins. — bullish pressure on SPY.
