US national debt above $40 trillion: IMF chief says growth alone cannot fix it

The US national debt, which crossed 40 trillion dollars for the first time in August 2026, stood at about 40.3 trillion dollars in mid-October, according to Treasury data cited on 16 October. At the IMF and World Bank annual meetings in Bangkok on Wednesday, 14 October 2026, IMF Managing Director Kristalina Georgieva said the growth-first plan of US Treasury Secretary Scott Bessent would not bring the deficit and debt down quickly enough, and called for fiscal consolidation, meaning spending cuts or higher revenue. "Growth of course helps, but it cannot deliver fast enough the necessary adjustments," she said. A Treasury official responded by questioning the IMF's past forecasting record.

US government bonds sit at the centre of the world's financial system. When US debt grows quickly, the government has to sell more bonds, and investors may demand higher interest rates to keep buying them. Higher US rates ripple outward: they raise borrowing costs for companies and governments everywhere and can pull money out of emerging markets.

The argument between the IMF and the US Treasury is about arithmetic and politics. Bessent's view is that a fast-growing economy will make the debt smaller relative to the size of the economy, even if the debt itself keeps rising. Georgieva's view is that growth is welcome but too slow on its own. The numbers explain the gap: the head of the Congressional Budget Office, Phillip Swagel, has said that stabilising the debt would need growth of 5% to 6%, while economists expect real US growth of only a little above 2% this year.

The speed of the rise has also surprised forecasters. The Congressional Budget Office had projected in 2023 that the debt would reach 40 trillion dollars in 2028. It got there about two years early. With interest costs now around 1.1 trillion dollars a year, a growing share of federal spending goes simply to servicing past borrowing, leaving less room for anything else.

For India, the debate matters indirectly but clearly. US interest rates influence how much foreign money flows into Indian shares and bonds, the value of the rupee, and the cost of dollar loans for Indian companies. A US government that keeps borrowing heavily without a plan to slow it down could keep global rates higher for longer, which tends to make conditions harder for emerging economies.

Short-term: Bond investors will watch for any sign of the fiscal consolidation package Bessent has discussed but not detailed. The public disagreement between the IMF and the Treasury adds to pressure on Washington ahead of coming budget fights.

Long-term: If debt keeps rising faster than the economy, interest payments will take a larger slice of the US budget, and the risk of higher long-term interest rates around the world grows.

Who is affected: US taxpayers and borrowers; global investors in US government bonds; and emerging economies, including India, whose currencies and capital flows respond to US interest rates.
