China's Public Debt Under Pressure: When Will the Day of Reckoning Arrive

China faces an increasingly pressing fiscal challenge. With public debt reaching astronomical levels, the country is under growing pressure to manage debt service payments. Official figures at the end of 2025 show China’s total public debt had reached about 526.8 trillion yuan, roughly 375,000 yuan per capita. This situation raises critical questions about long-term sustainability.

When expenses exceed income: the 2025 budget deficit

The starting point to understanding China’s public debt crisis is examining the national fiscal budget. In 2025, projected revenue was 21,604.5 billion yuan, while expenditures were estimated at 28,739.5 billion yuan. This gap results in an impressive deficit of about 7,135 billion yuan. To put this in perspective, it accounts for over 33% of total tax revenue and about 5% of the projected national GDP. The imbalance between income and spending forces the government to heavily rely on issuing new debt to cover the budget shortfall.

Interest costs consume an increasing share of tax revenue

One of the most alarming aspects is the cost of servicing existing debt. According to data from the People’s Bank of China, the outstanding government bonds in circulation were expected to reach 95.44 trillion yuan by the end of 2025. Applying an estimated average interest rate of 3.5%, interest payments would have absorbed about 3.34 trillion yuan that year.

These numbers tell a worrying story: interest on public debt consumes about 15.5% of total tax revenue. In other words, nearly one yuan out of every six in tax income is simply used to pay interest. Even more significant is that these payments represent 46.8% of the new annual deficit, meaning almost half of all borrowed money is immediately absorbed by servicing existing debt.

The vicious refinancing cycle: the cycle of public debt

Analyzing the debt flow dynamics reveals a troubling mechanism. At the end of 2024, the national debt was 81.58 trillion yuan and was expected to grow to 95.44 trillion by 2025, a net increase of 13.86 trillion yuan. However, total new debt issuance in 2025 was set at 26.3 trillion yuan, a figure significantly higher than the actual net increase in total debt.

How is this possible? The answer lies in refinancing. Of the 26.3 trillion yuan of new debt issued:

• 12.44 trillion was allocated to refinancing maturing debt
• 3.44 trillion was reserved for paying annual interest
• Only 10.42 trillion could be used for new spending

This reveals a concerning dynamic: a substantial portion of the enormous amount of national debt issued each year simply serves to “extend” existing debt, creating a cycle of dependence on credit that becomes increasingly difficult to sustain.

The hidden side: Chinese private debt

When assessing China’s overall risk profile, private debt cannot be ignored. Excluding government bonds, Chinese private debt (combining household and corporate debt) amounts to about 370 trillion yuan. Including official public debt, China’s total debt approaches 470 trillion yuan. This figure does not even account for various forms of implicit debt not recorded in official statistics, which could add an additional layer of vulnerability to the overall economic picture.

The growing pressure on Chinese public debt, combined with high levels of private borrowing, creates a scenario where fiscal maneuvering space continually shrinks. The ability to manage future economic crises or invest in new development initiatives increasingly depends on further extending existing debts—a situation that poses a rising risk to China’s long-term economic stability.
