The U.S. national debt surpassed $40 trillion this week, raising concerns regarding the potential impact on American finances. Although individuals do not directly owe this debt, rising federal borrowing may lead lawmakers to consider tax increases, spending cuts, or changes to federal benefits.
The gross federal debt reached this milestone on Wednesday, which includes debt owed to itself. Economists typically focus on the approximately $32 trillion held by the public when evaluating the debt's economic effects. The tax and spending law enacted during President Trump's administration is expected to contribute significantly to federal deficits over the next decade, alongside requests for additional funding related to the conflict in Iran.
Higher national debt could result in increased costs for mortgages, student loans, and small-business borrowing due to upward pressure on interest rates, as indicated by a report from the Conference Board. If investors perceive U.S. debt as riskier, they may demand higher yields, further driving up borrowing costs for businesses and individuals.
Mortgage rates are closely linked to the yield on the 10-year Treasury note, which reflects the return investors expect for lending to the federal government. As Treasury yields rise, mortgage rates are likely to follow suit, leading to increased costs for various types of loans.
Additionally, high national debt may exacerbate inflation concerns if investors fear that policymakers will resort to inflationary measures to address fiscal issues. The federal government is projected to spend over $1 trillion on net interest payments in 2026, which could limit funding for other priorities such as defense and education.
Currently, there appears to be little political will in Washington to alter the nation's fiscal trajectory, leaving the debate over spending and taxes unresolved. However, there is a growing awareness among Americans regarding how national debt may affect their financial situations, particularly through rising mortgage rates, which could influence voting behavior in upcoming elections. Sustainable management of federal debt will likely require a combination of reduced spending growth and increased revenue.
