Watch: How does the US national debt affect consumers around the world?

The United States national debt has reached a significant milestone of $40 trillion, representing more than a doubling from the approximately $20 trillion recorded in 2016. This dramatic increase stems from substantial government spending during both the Trump and Biden presidential administrations, compounded by rising interest payments that continue to add to the overall debt burden. The BBC's Nathalie Jimenez provides analysis explaining how this massive debt level has implications not only for American consumers but also for people and economies worldwide.
