The Independent ↗How it started
The US has long relied on borrowing to fund government programs, defense, and emergency responses. Over the past decade, this borrowing accelerated sharply. According to Quartz and TIME.com, the national debt has doubled in ten years, fueled by major policy decisions, tax cuts, and large-scale spending.
Much of this growth took place after 2022, with about $10 trillion added in just four years, as noted by the South China Morning Post. Analysts point to increased spending on Social Security, healthcare, and defense, as well as responses to economic disruptions and wars, as key contributors. Political debates over taxes and spending have often stalled efforts to rein in the deficit.
How it unfolded
By mid-August 2026, the debt had reached $40 trillion, a figure not seen since wartime peaks, according to El Colombiano. On August 18, the total debt officially topped $40.047 trillion, with roughly $32.3 trillion held by the public and $7.8 trillion as intragovernmental holdings, reported by TABNAK.
As the milestone approached, rising Treasury yields became a major concern. The Hill and CBS Top Stories described how 30-year Treasury yields hit their highest point in nearly two decades, prompting Treasury Secretary Scott Bessent to intervene. The US Treasury announced plans to double long-duration bond buybacks to at least $4 billion, hoping to ease pressure on government borrowing costs (Time.news, August 20).
Throughout August, coverage by Reuters, the BBC, and others reflected growing alarm among investors and policymakers. Interest payments on the debt now exceed $1 trillion annually, as Euronews and DIE WELT reported, sometimes surpassing even the military budget. The rapid increase in government debt and higher interest rates have also affected mortgage rates and the broader financial markets, according to The Independent and MarketWatch.
Political debate has intensified, with both parties blaming each other while continuing deficit spending, as Reason and NYT Politics observed. Despite the scale of the problem, there has been little political appetite for major spending cuts or tax hikes.
Where it stands
The US national debt stands at over $40 trillion, equal to or greater than the country's annual GDP, according to several outlets including El Colombiano and Daily Mail. Interest costs are at historic highs. Federal spending continues to outpace revenue, and the government is taking unusual measures to stabilize the bond market.
This debt level has led to higher borrowing costs, market volatility, and concerns about the sustainability of US fiscal policy. Experts disagree about the risk of a fiscal crisis. Some, like those cited by the New York Post, argue there is no immediate danger, while others warn of potential shocks to the economy and global markets.
What to watch
Lawmakers face difficult choices ahead. Many analysts and outlets, including Mehr News and The Conversation, say that unpopular spending cuts or tax increases may be needed to slow the debt's growth. If current trends continue, some traders are already watching for a $50 trillion debt within a few years (Seeking Alpha).
The effectiveness of the Treasury's interventions is still being debated, and their impact on interest rates, mortgage payments, and the value of the dollar will be closely watched in the coming months.
