Of course, China's debt is still rising－a trend that, if left unchecked, could pose a mounting threat to financial and economic stability. But the structure of China's national balance sheet suggests it still has plenty of room to mitigate the risks that escalating debt might bring.

Thanks to China's high savings rate, its banking system had a loan-to-deposit ratio of 74 percent at the end of 2015, with 17.5 percent in required reserves held at the central bank. The capital adequacy ratio was as high as 13.2 percent. Given that China's net external lending position amounts to $1.8 trillion, or 17.2 percent of GDP, the central bank has enough liquidity to reduce banks' reserve requirements without resorting to unconventional monetary policy.

Furthermore, after more than three decades of rapid income growth, China has accumulated wealth (or net assets) in almost all sectors. By any standard, China's household sector has very low leverage, with a debt-to-deposit ratio of 47.6 percent. Even the corporate sector's leverage is not as high as many reports suggest. Household deposits accounted for 40.1 percent of total bank deposits of 146.5 trillion yuan ($22.5 trillion) at the end of March 2016, while non-financial corporations comprised 32.1 percent and the share of government deposits was 17.1 percent. The combined debt-deposit ratio of the non-financial corporate sector and the government sector was 97.6 percent, which means these sectors' total deposits exceeded their debts to the banking system by 1.7 trillion yuan.

In addition, the Chinese Academy of Social Sciences estimates that the central and local governments have accumulated net assets of nearly 146 percent of GDP, mostly in real estate. In short, while China has a problem with inefficient capital allocation, it is nowhere near a solvency or liquidity crisis.

Giacomo Corneo of the Free University of Berlin has proposed that, in addition to taxing underused real estate, China should create a sovereign wealth fund to improve the management of public assets. Given that those assets amount to an estimated $18 trillion, a higher return on capital would boost GDP and reduce debt. China's bank regulators have already permitted experiments in debt-equity swaps, which the International Monetary Fund says should be incorporated in a comprehensive strategy to accelerate the reform of State-owned enterprises.

China has the savings to address its growing debt burden. Amid slowing growth, however, its window of opportunity is narrowing. The sooner China rebalances from debt to equity, the better off it will be.
