America’s $40 trillion national debt isn’t just making borrowing more expensive — it might also be helping Washington’s biggest geopolitical rival.

On Aug. 19, the Treasury Department announced that the national debt had surpassed $40 trillion, marking a new milestone. But the bigger story isn’t the number itself — it’s what it signals about Treasury bondholders. Even as the Federal Reserve holds off on raising interest rates, pressure continues to build across the economy. The concern isn’t confined to U.S. borders, either: Chinese government bonds may be quietly emerging as an alternative to American debt in the eyes of global investors.
