Donald Trump returned to the White House with a promise to bring greater discipline to US government finances. He pledged to reduce the size of government, cut waste and encourage stronger economic growth.
Instead, the US national debt has now climbed above $40 trillion during the first 19 months of his second term.
Federal spending has continued to rise, while the cost of servicing the nation’s debt has also increased. Higher Treasury yields have added further pressure to the government’s finances.
The growing debt burden is raising concerns among economists and budget experts. They warn that future administrations and Congress could eventually face difficult choices over taxes, government spending and major social programs.
US debt continues to climb
The United States has carried large budget deficits for years, with both Republicans and Democrats contributing to the long-term increase.
Trump’s first-term tax cuts added an estimated $8.4 trillion to the national debt, according to the Committee for a Responsible Federal Budget.
His second-term tax and immigration legislation is expected to add another $4.7 trillion, based on estimates from the Congressional Budget Office.
The White House argues that Trump’s policies have reduced waste and improved government efficiency. Officials point to cuts involving federal workers and programs they consider unnecessary.
However, those measures have not stopped the overall debt from increasing.
The annual deficit fell slightly in 2025, but the improvement was not large enough to reverse the broader trend.
Both parties face responsibility
The country’s fiscal problems did not begin with Trump.
Republican administrations under Ronald Reagan and George W. Bush introduced major tax cuts that contributed to wider deficits. The Bush administration also faced the enormous costs of wars in Afghanistan and Iraq.
Democratic administrations have also increased federal spending during major economic emergencies.
Barack Obama oversaw large stimulus measures following the 2008 financial crisis. Joe Biden approved significant spending programs during and after the COVID-19 pandemic.
Bill Clinton offers a contrasting example. During his second term, the United States recorded annual budget surpluses as strong economic growth and spending reforms helped improve government finances.
Social Security faces pressure
Demographic changes have added another challenge.
Millions of Americans from the baby-boom generation are now retiring. That means Social Security and Medicare face growing financial pressure as the number of beneficiaries rises.
At the same time, payroll tax revenue does not cover all future benefit obligations.
The issue creates a difficult political problem for lawmakers. Reducing benefits could anger voters, while raising taxes could face strong opposition.
Trump has also moved away from some traditional Republican calls for major entitlement reform.
Instead, his administration has emphasized other approaches to raising revenue and supporting household finances.
Trump bets on economic growth
Trump has repeatedly argued that faster economic growth can help solve the country’s fiscal problems.
His broader economic strategy includes tax reductions, tariffs and deregulation. Supporters believe these policies can encourage investment, increase economic activity and ultimately generate more government revenue.
Trump has expressed strong confidence in the potential for economic expansion.
Budget experts, however, warn that growth alone may not be enough to close the gap between government spending and revenue.
The Federal Reserve has also highlighted the financial pressure created by enormous investment in artificial intelligence and technology.
Strong demand for capital can push borrowing costs higher. That can make it more expensive for the government to finance its growing debt.
Government efficiency falls short
Trump also promised major reductions in federal spending during his campaign.
Elon Musk was brought in to lead the Department of Government Efficiency, with an ambitious target of cutting as much as $2 trillion from government spending.
The initiative ultimately reported around $110 billion in savings.
The Government Accountability Office later questioned some of the reported figures, saying they included claims that were overstated or could not be verified.
That gap between the original ambition and the reported savings illustrates the difficulty of making large reductions to federal spending.
Many government programs have powerful political support, making major cuts difficult for lawmakers to achieve.
Rising debt affects Americans
The impact of the US national debt extends beyond Washington.
Higher government borrowing can contribute to higher interest rates across the economy. Mortgage rates, business loans and other forms of borrowing can all feel the effects of movements in Treasury yields.
Higher debt costs can also leave the government with less money to spend on other priorities.
That creates a growing concern for future budgets.
If interest payments continue to consume a larger share of federal revenue, lawmakers could eventually have less flexibility during economic downturns or national emergencies.
A difficult fiscal choice ahead
The United States now faces a fiscal challenge that has developed over decades.
Trump inherited a large debt burden, but his policies have not reversed the trend. Instead, the national debt has continued to grow while borrowing costs remain a concern.
Budget experts say the country will eventually need to address the imbalance between spending and revenue.
That could require a combination of spending reductions, tax increases or changes to major entitlement programs.
None of those options would be politically easy.
For now, Washington continues to rely heavily on borrowing. But with the US national debt above $40 trillion, the room for avoiding difficult decisions is becoming increasingly narrow.
The central question for Trump, Congress and future administrations is no longer simply how to reduce government spending. It is whether policymakers can agree on a long-term plan before rising debt and interest costs create an even larger financial burden for American taxpayers.
