China’s debt interest costs are soaring above U.S. levels and growing faster than any other budget category as Beijing struggles to prop up growth

The world is flooded with debt, but while the U.S. and Europe have caused angst on global markets lately, China’s fiscal situation isn’t looking so great either.

In fact, China’s debt has shot up so much in recent years that interest payments on all its borrowing are commanding a bigger share of public spending.

Debt-servicing payments will account for 19.2% of the central government’s general public budget this year, up from 12% in 2014, according to new Conference Board estimates cited by the Financial Times .

That tracks with a separate report earlier this year from the Center for Strategic and International Studies , which also found that 19% of Beijing’s spending is earmarked for interest on debt.

That’s more than the 14% of the U.S. federal budget that goes to interest costs, though less than Japan’s 25.6%.

CSIS added that China’s spending on interest payments skyrocketed 341% between 2013 and 2025, faster than any other major budget category.

By comparison, total spending jumped 102% in that span, with outlays on social security and employment up 207%, science and technology up 137%, and defense up 141%.

To be sure, U.S. debt-interest spending looks grim too and has surged about 390% since 2013 to $1 trillion, which also tops the Pentagon’s budget.

But the world’s two biggest economies have been diverging in key ways with implications for future growth and indebtedness.

The U.S. economy is accelerating, helped by the AI boom, and despite high inflation, resilient consumers have continued to spend.

Unemployment is low and signals full employment, while stock markets are at or near record highs.

Of course, hyperscalers are racing to issue bonds to fund their data centers and chip purchases, but they are also raising money with fresh stock offerings and IPOs.

Meanwhile, China’s GDP has been decelerating and is on pace to undercut its annual target of 4.5%-5%.

And while export-facing sectors are growing at a fast clip, trade partners are putting up barriers, Chinese consumers remain reluctant to spend, investment is weak, the property sector is still digging out from an epic crash, and Chinese stocks have been anemic.
