China's Public Debt Crisis Reaches Critical Point: 526.8 Trillion Yuan and Unsustainable Pressure

By the end of 2025, China’s fiscal situation reached new record highs, raising increasingly urgent questions about the sustainability of China’s public debt. With a total amount of approximately 526.8 trillion yuan, the public debt translates to about 375,000 yuan per Chinese citizen. But what do these numbers really mean? And how long can this financing structure hold before reaching a breaking point?

China’s Budget Deficit in 2025: When Revenues Fall Short

The fundamental question is simple: how much does the government spend compared to how much it collects? In 2025, total tax revenues amounted to 21.6045 trillion yuan, while public expenditures reached 28.7395 trillion yuan. The difference is telling: a deficit of 7.135 trillion yuan.

This gap accounts for about one-third of public revenues. In terms of national GDP (estimated around 140 trillion yuan), the deficit equals 5% of the total wealth produced. At first glance, this might seem manageable, but here emerges the first critical issue: this huge budget shortfall must be financed almost entirely through new public debt issuance. This means that each year, the state borrows massive sums to cover the gap between revenues and expenditures.

The Burden of Public Debt Interest Payments: Nearly Half of New Borrowing

The problem becomes dramatically more complicated when considering the cost of servicing the debt. According to data from the People’s Bank of China, the outstanding government bonds reached 95.44 trillion yuan by the end of 2025. Applying an average interest rate of 3.5%, interest payments on this debt amount to about 3.34 trillion yuan annually.

What does this mean in practice? Nearly 1 yuan out of every 6 in all tax revenues is allocated solely to interest payments. In other words, of the 21.6 trillion yuan the government collects annually, about 15.5% is already spent before accounting for regular expenses. But there is an even more alarming metric: of the 7.135 trillion yuan the government borrows each year, nearly 46.8% is absorbed by interest payments. Almost half of the new borrowed money simply goes to pay interest on previous debt, not to finance new investments or current expenses.

How Money Flows: The Vicious Cycle of Debt Refinancing

To truly understand the pressure on China’s public debt, one must trace the flow of money. At the end of 2024, the total national debt balance was 81.58 trillion yuan. By the end of 2025, this grew to 95.44 trillion yuan, representing a net increase of 13.86 trillion yuan.

Meanwhile, total new debt issuance in 2025 reached 26.3 trillion yuan. But where did all this money go? The answer reveals the true nature of the crisis:

• Refinancing maturing debt (debt rollover): 12.44 trillion yuan
• Interest payments for the year: 3.34 trillion yuan
• Actual available for new spending: 10.42 trillion yuan

Only about 40% of the new debt issued is truly usable for funding new projects or public services. The remaining 60% is used to extend existing debt and cover service costs. This mechanism creates a vicious cycle: each year, to cover past debt, new debt must be issued, which in turn generates new interest payments in future years.

The Full Picture: Chinese Public and Private Debt, What Future?

The problem significantly widens when looking at debt in a broader sense. Chinese private debt (including households and businesses), excluding government bonds, amounts to about 370 trillion yuan. When considering public debt as well, total indebtedness approaches 470 trillion yuan. This figure does not even include some implicit and off-balance-sheet debts that escape official statistics.

The tension generated by this level of indebtedness carries serious implications: reduced capacity to manage economic crises, diminished fiscal policy flexibility, and a shrinking margin of maneuver to address external shocks. China’s public debt is no longer just a statistical number but represents a tangible pressure on the future sustainability of the global second economy.

The question is no longer whether the system will be tested, but when and how the Chinese government will manage to recalibrate this delicate balance without compromising economic stability and growth.
