The US national debt has exceeded $40 trillion, a significant increase from just under $20 trillion in 2016, reflecting a decade of heavy spending and rising interest payments under both the Trump and Biden administrations.1

The Congressional Budget Office (CBO) warns that the nation is approaching its $41.1 trillion debt ceiling, with projections indicating a staggering $64 trillion by 2036.2

Jacks from the National University of Singapore noted, "The pace of America's growing debt is accelerating and at some point, the bills will come due."

The debt-to-GDP ratio stands at 125.8%, according to the International Monetary Fund (IMF), which is significantly higher than the UK and China's ratios of 103.6% and 106.9%, respectively. Japan leads with a debt-to-GDP ratio exceeding 200%.
