About US National Debt
The US National Debt represents the total amount owed by the federal government. It has grown significantly in recent decades, exceeding $36 trillion. The debt grows when the government runs budget deficits, spending more than it collects in revenue. Tracking absolute debt levels helps investors understand fiscal sustainability and potential impacts on bond markets and interest rates.
