China's interest bill soars 341% to 19% of budget, topping US

China's interest bill has become the fastest-growing line in the central government's budget. Debt-servicing payments will eat 19.2% of the general public budget this year, up from 12% in 2014, according to Conference Board estimates cited by the Financial Times. That matches a separate CSIS analysis that put the share at 19% - and it's a bigger slice than the 14% the U.S. spends on interest, though still below Japan's 25.6%. The figure is a stark reminder that the world's second-largest economy is now spending nearly one in five budget dollars just to service what it already owes.

The jump is staggering: interest spending skyrocketed 341% between 2013 and 2025, faster than any other major budget category. Total spending rose 102% in that span, while social security and employment outlays grew 207%, science and technology 137%, and defense 141%. The numbers underscore how Beijing's debt-fueled stimulus is now compounding against itself. Every new yuan borrowed to support growth adds to the interest bill, which in turn consumes more of the budget, leaving less for the productive spending that could actually revive the economy.

To be sure, America's interest burden is also heavy - up roughly 390% since 2013 to $1 trillion, which tops the Pentagon's budget. But the two economies are diverging in ways that matter for global investors. The U.S. is accelerating on AI-driven growth, with low unemployment and record stock markets. China's GDP is decelerating, on pace to miss its 4.5%-5% target, with weak consumption, anemic investment, a property sector still digging out from an epic crash, and trade barriers piling up. The contrast is not just about growth rates; it's about the quality of the debt behind them.

Beijing has directed state banks to finance priority industries - EVs, robotics, AI, renewables - but the push has produced questionable lending. Business debt has doubled since 2019 while revenues are only 30% higher. Creditors keep rolling over loans to keep struggling firms afloat, even as nearly a third of them lose money. The result is a banking system propping up unproductive firms, widespread losses, and entrenched overcapacity. This is the classic late-cycle dynamic: credit keeps flowing to keep the system alive, but it's not generating the returns needed to service itself.

The scale of the debt is hard to overstate. The IMF puts China's general government gross debt at 107% of GDP this year, up from 41% in 2015 and on track for 124% by 2030. A broader measure - total public and private debt excluding the financial sector - has doubled since 2010 and now tops 300% of GDP, per Capital Economics. The U.S., by contrast, saw total debt fall to about 265% of GDP last year, down from pandemic peaks. China's debt-to-GDP ratio is now higher than America's on the broadest measure, and it's still climbing.

The strain is visible across the economy. Export-facing sectors are growing at a fast clip, but trade partners are putting up barriers. Chinese consumers remain reluctant to spend, investment is weak, and the property sector is still digging out from an epic crash. Local governments, which often seek to boost favored industries with low-cost loans, are adding to the pile. The state-led growth model that powered China for two decades now looks like it's running out of steam, and the rapidly expanding mountain of debt is a warning sign for anyone doing business in or with the country.

Mark Williams, chief Asia economist at Capital Economics, captured the paradox: 'The irony is that one driver of both government borrowing and the lax lending standards of [state-owned] banks is the desire to prop up economic growth and prevent job losses. But the product of a credit boom that has been underway for 18 years is a banking system propping up unproductive firms, widespread losses across industry, and entrenched overcapacity.' For executives and investors, the takeaway is that China's fiscal headroom is shrinking exactly when the economy needs support - and the cost of propping up growth is becoming a drag on it. The next policy move will likely be more of the same: more debt, more rollovers, and more interest payments, until the math forces a reckoning.
