China's debt-to-GDP ratio has climbed to one of the highest levels among major economies — second only to Japan — after a surge in borrowing over the past 10 to 15 years that analysts describe as among the fastest in recorded history. According to an analysis published by the Carnegie Endowment for International Peace, the pace of debt accumulation has rendered further growth on the current trajectory unsustainable.

Roots of the Crisis: The 2000 Banking Cleanup

The seeds of today's debt problem were sown in how Beijing handled its earlier banking crisis around 2000. By the late 1990s, China's Big Four state-owned banks were technically insolvent, weighed down by massive quantities of non-performing loans. Official estimates placed non-performing loan ratios at 25 to 30 percent of total portfolios, while independent analysts — including the World Bank — believed the true figure was closer to 40 to 50 percent.

As the Carnegie analysis by Professor Michael Pettis notes, moving bad loans from one balance sheet to another does not eliminate them. It merely redistributes who ultimately bears the loss.

Financial Repression: Households Paid the Price

Contrary to widespread perception, the Chinese government did not primarily absorb those losses through the public budget. Instead, Beijing relied overwhelmingly on financial repression — a mechanism that shifted the burden almost entirely onto the Chinese household sector.

Deposit rates on household savings were kept well below nominal GDP growth and, for extended periods, even below inflation. Because households made up the overwhelming majority of net savers, they earned extraordinarily low — and often negative — real returns on their bank deposits. Meanwhile, businesses, state-owned enterprises, and local governments borrowed at artificially suppressed interest rates, effectively receiving a hidden subsidy at savers' expense.

The banking system was recapitalised, but the cost was borne by ordinary Chinese households — largely without their awareness. This, Professor Pettis argues, makes the common claim that China resolved its banking crisis at 'little cost' deeply misleading.

Consumption Collapse and Structural Imbalance

The consequences were dramatic. As late as 2000, household consumption represented 63.9 percent of China's GDP. Rather than rising — as most economists expected following the completion of the initial industrialisation phase — it collapsed. By 2010, household consumption had fallen to just 49.4 percent of GDP, the lowest share ever recorded in any major economy, according to the analysis.

Household income declined as a share of GDP, dragging consumption down with it. At the same time, businesses and local governments gained access to exceptionally cheap capital, accelerating investment even as household purchasing power weakened. This structural imbalance has left China heavily dependent on exports to sustain growth.

That export dependence has had global consequences. The flood of competitively priced Chinese goods has hurt industries across the world, stoking trade tensions and prompting tariff responses from multiple economies.

The Risk of Repeating the Same Mistake

China now confronts what the Carnegie analysis describes as an enormous new debt overhang. The critical question, according to Professor Pettis, is whether policymakers will attempt to resolve this crisis the same way they resolved the last one.

'If policymakers attempt to resolve today's debt burden in the same way they resolved the last one — by once again transferring resources from households to producers and governments — they may stabilise the financial system temporarily, but they will also deepen the very structural imbalances that have made China's adjustment so difficult and contributed to the rapid accumulation of debt over the past fifteen years,' the analysis concludes.

The warning signals that without a genuine rebalancing toward household income and consumption, any near-term financial stabilisation risks laying the groundwork for an even larger crisis ahead.
