Unsustainable tax and spending policies have pushed the U.S. national debt to a record $40 trillion. A recent government intervention highlights the severity of the situation, with bond yields spiking and the risk of a financial crash looming if fiscal discipline is not restored.
tax and spending plans, which have pushed US debt to an eye-watering $40 trillion , are coming undone, stoking a full-on fiscal crisis in the world’s most powerful economy.

The dollar has been the global reserve currency since the It’s too big to fail, isn’t it. Yes, it probably is. But it’s not too big to have another 2008-style financial crisis.
AI companies are starting to sound desperate, and that’s not a good lookLast week’s surge in 30-year US bond yields – they touched 5.3 per cent, a level not seen since 2007 – sent tremors through financial markets and prompted a US government intervention to prop up the market.announced he was doubling long-term debt buy-backs to $4 billion to tame the spike in bond yields . The intervention came just weeks after Washington’s surprise intervention to buy Japanese yen, a move that was also designed to support US treasuries.
The speed at which US debt has grown is mind-numbing. It first reached $1 trillion in 1941. It hit $20 trillion in 2017, then doubled to $40 trillion in the intervening nine years. Since Trump took office, for a second time, in January 2025, the US debt load has increased by $3.8 trillion, for total growth of $11.6 trillion across his two terms.
Public debt increased by $8.4 trillion during Biden’s term, driven by spending on Covid, infrastructure investment and clean energy subsidies. Washington’s inability to get control of its annual budget deficit is not unrelated to the polarised politics that surrounds it. Tackling it requires either cutting public spending or raising taxes or both, a political venture that neither Republicans or Democrats are willing to undertake, given the likely voter backlash.
Both parties talk like fiscal hawks when in opposition and spend like drunken sailors when in office. The cost of servicing it is now $1.2 trillion annually, bigger than the country’s defence budget.

They dominate our export trade. Foreign-owned enterprises accounted for 87 per cent of the value of our exports in 2022, the Central Statistics Office has said.
