US National Debt Surpasses $40 Trillion Amid Rising Interest Rates

The United States' national debt has surpassed $40 trillion for the first time in history. This staggering figure represents roughly $117,000 per American and nearly $297,000 per household. The US Treasury confirmed this milestone on August 18, months ahead of forecasters' expectations just a year ago.

The national debt is essentially a mortgage or business loan that has been accumulating over the years due to government spending exceeding tax revenues. Think of it like borrowing money from investors, mostly by selling Treasury bonds, bills, and notes. This accumulated debt stands at around 124% of US GDP, surpassing the country's entire annual economic output.

While countries have used debt for centuries to fund wars, recover from crises, and build infrastructure and technology, the concern lies in the math behind it. Interest rates have climbed sharply since 2022, making it more expensive for the government to service its debt, which is now rising faster than the economy itself.

The largest portion of America's $40 trillion debt belongs to domestic private investors, including American mutual funds, banks, insurers, pension funds, and households. The Federal Reserve holds a significant amount through its own bond portfolio, while foreign investors, such as Japan, hold around 29% of publicly held debt.

The popular image that America is deeply indebted to the rest of the world is misleading. In reality, roughly four-fifths of the $40 trillion is owed to Americans, American institutions, or the government itself.
