Hong Kong CNN — Three years of strict pandemic controls in China and a real estate crash have drained local government coffers, leaving authorities across the country struggling with mountains of debt. The problem has gotten so extreme that some cities are now unable to provide basic services, and the risk of default is rising. Analysts estimate China’s outstanding government debts surpassed 123 trillion yuan ($18 trillion) last year, of which nearly $10 trillion is so-called “hidden debt” owed by risky local government financing platforms that are backed by cities or provinces. As the financial pressure has mounted, regional governments have reportedly been slashing wages, cutting transportation services and reducing fuel subsidies in the middle of a harsh winter. Thousands of people in the northern province of Hebei had trouble heating their homes in November and December because of a shortage of natural gas, according to multiple Chinese media reports. Cuts in government subsidies were partly to blame, according to state-owned news site Jiemian. In January, in the northernmost province of Heilongjiang, households in the city of Hegang were also left without heat after local firms severely restricted supply. The companies blamed the move on a lack of government subsidies. The lack of heating in the dead of winter has led to widespread complaints on social media. The central government in Beijing responded by ordering cities to provide adequate heating, but without specifying who will pay the bills. Local governments have exhausted their budgets after spending enormous amounts of money on enforcing frequent Covid lockdowns, mass testing and setting up quarantine centers before December’s policy U-turn, which signaled the abrupt end of Xi Jinping’s zero-Covid policy. “Beijing is facing an economic minefield of its own making,” said Craig Singleton, senior fellow for the Foundation for Defense of Democracies in Washington. “All told, China’s current debt crisis represents a perfect storm.” It’s not yet clear how much the country has spent in total on fighting the pandemic. But one province, Guangdong, revealed that it had spent $22 billion on eliminating Covid over the three years beginning 2020. Revenue, meanwhile, contracted sharply over the same period. Rolling lockdowns seriously dented household incomes, leading many to reduce spending, which in turn resulted in less tax revenue for local governments. Huge tax breaks to support businesses through the pandemic also reduced government income. Further complicating matters is the housing market slump; home prices have been falling for 16 straight months. Land sales, which typically account for more than 40% of local government revenue, have collapsed. Last year, a number of cities suspended bus services due to budget constraints, including Leiyang in Hunan province and Yangjiang in Guangdong, according to operators’ announcements. Separately, Hegang, the city in Heilongjiang province, made history in early 2022 by becoming the first to be forced to undergo a fiscal restructuring due to serious debt distress, according to state media reports. As a result, it must cut spending on infrastructure projects, reduce government subsidies to industries, stop hiring new staff and sell assets, according to rules published by the State Council. Public sector jobs, considered the most secure in the country, were also affected elsewhere. In June, several wealthy eastern provinces — including Guangdong, Zhejiang and Jiangsu — slashed pay by as much as 30%, according to Chinese news website Caixin. “China’s runaway local debt poses a serious threat to the country’s overall economic health and will weigh heavily on China’s still-nascent recovery,” said Singleton. The debt inhibits the government’s ability to spur growth and stabilize employment, as well as maintain or expand public services, he said. “No doubt, China’s current debt crisis has the potential to exacerbate existing socio-economic tensions,” Singleton said, adding that renewed public protests like those in late 2022 could emerge, as Chinese citizens come to terms with “vanishing jobs, closed businesses and reduced wages.” China’s local government debt had already been rising dramatically for a decade before the pandemic, largely the result of a state-led investment boom in the wake of the 2008 global financial crisis. But the situation has deteriorated rapidly in the last three years. Last year, local government debt jumped 15% to 35 trillion yuan ($5.2 trillion), according to data released by the Ministry of Finance on Sunday. Interest payments on local government bonds exceeded one trillion yuan ($148 billion) for the first time in history, according to state media. Debt that is backed by local governments but which doesn’t show up on their balance sheets could be much bigger. The “hidden debt” issued by local government financial vehicles, entities created to circumvent borrowing restrictions and used to channel funding for infrastructure spending, might have totaled 65 trillion yuan ($9.6 trillion) by the middle of 2022, according to a recent estimate by analysts at Mars Macro, an economic research firm based in Hunan. That’s more than 20% higher than the estimate of 53 trillion yuan made by Goldman Sachs in 2021. That would be equivalent to more than half of China’s GDP. Overall, Chinese government debt is now equivalent to 102% of its GDP, the analysts estimated. That debt ratio is still lower than America’s, which is currently about 122%, based on its national debt and GDP in 2022, but China’s has grown at a staggering rate, more than doubling from 47% in 2016. There are already signs local governments are having trouble repaying their liabilities. In early January, a troubled government-owned company in the southwestern province of Guizhou responsible for building infrastructure projects announced that its lenders had given it an extra 20 years to repay loans worth $2.3 billion. Loan rollovers with such a long time frame are extremely rare in China. Analysts said the case signals that local governments are under severe financial pressure this year. Their debt squeeze could pose a serious threat to China’s financial system, particularly to small regional banks. “Once defaults begin, suggesting that government guarantees have broken down among LGFVs [local government financing vehicles], defaults can snowball quickly,” Allen Feng and Logan Wright, China analysts at Rhodium Group, wrote in a research report last week. “As a result, there is a significant risk of financial contagion,” they said. “Smaller city and rural commercial banks are particularly vulnerable because of their deep relationship with local governments.” Even the country’s top officials have admitted that one of the biggest threats to financial stability in 2023 is hidden local government debt, which is opaque, huge and hard to track. The central government in Beijing has signaled it’s not coming to the rescue. “If it’s your baby, you should hold it yourself,” the Ministry of Finance warned in a statement earlier this month aimed at local authorities. “The central government won’t dance [you] out.” But Beijing may have to allow provinces and cities to borrow more. China’s economy is in a severe downturn. GDP grew only 3% last year, the second worst growth in 46 years. The government had previously resorted to the old playbook of encouraging local governments to borrow more money to fund infrastructure projects to boost growth. In December, an infrastructure push helped boost economic activity, leading to signs of growth stabilization. In January, Bloomberg reported that Chinese authorities were considering a record quota for special local government bonds this year. “So far, it seems that Xi badly needs a fast recovery of the economy, and has chosen to shelve the debt problem for later,” said Adam Liu, an assistant professor at the National University of Singapore. —Yong Xiong contributed reporting.
