US debt was its own revolutionary masterstroke that helped launch a global financial superpower

Key Points:

• The foundation of U.S. financial strength dates back to Alexander Hamilton's 1790 decision to consolidate Revolutionary War debts into a single national debt, establishing the country's creditworthiness and enabling it to borrow cheaply.
• Hamilton's plan committed the federal government to fully repay war debts, which built investor confidence and allowed U.S. Treasury bonds to be traded internationally, underpinning the global financial system and reinforcing the U.S. dollar as the top reserve currency.
• Today, U.S. debt stands at $39 trillion, equal to the size of the entire economy, with annual interest costs exceeding $1 trillion; rising debt levels and fiscal challenges have raised concerns about long-term sustainability.
• The Penn Wharton Budget Model warns that surpassing a debt-to-GDP ratio of 210% could trigger a solvency crisis, making default or cuts to programs like Social Security nearly inevitable, though current projections place this threshold decades away depending on economic and healthcare cost growth.
• Despite growing debt concerns, U.S. Treasury securities remain the world's most liquid and widely held assets, with strong investor demand continuing, although recent auctions have required higher yields to attract buyers.
