What Could Happen If US Debt Continues to Rise?
If U.S. government debt continues to increase at a sustained pace, the long-term impact could become more significant for public finances and the broader economy. A growing debt burden can lead to higher interest costs as the government needs to devote more of its revenue to servicing existing debt. Over time, this could reduce the funds available for infrastructure, healthcare, defence and other public programmes. Persistent borrowing could also place upward pressure on interest rates and make it more expensive for businesses and households to borrow. However, the impact would depend on factors including economic growth, government revenue, interest rates and the pace at which new debt is accumulated. A rising debt figure alone does not determine an economic crisis, but continued growth in debt relative to the economy could increase fiscal pressure over the longer term.
