China’s rising debt obligations are increasingly limiting the government’s ability to implement broad fiscal stimulus measures aimed at boosting domestic demand and supporting economic growth, according to recent analyses of state finances.

Interest payments on debt are projected to consume nearly one-fifth (19.2 percent) of the central government’s general public budget in 2026, a notable increase from 12 percent in 2014, according to a study from the US-based Conference Board. The pressure is particularly pronounced at the local government level, where annual growth in debt servicing costs has averaged 16 percent during the same period. Combined interest payments by central and local governments are expected to reach approximately 1.4 trillion yuan ($209 billion) this year, up sharply from about 348 billion yuan in 2014.

“Debt servicing is becoming a material constraint on fiscal space at the local level,” said Yuhan Zhang, principal economist at the Conference Board’s China Center. Analysts attribute the rapid growth in China’s debt to its investment-driven economic model, which depends heavily on state-backed loans and incentives. Public debt relative to gross domestic product (GDP) is forecast to reach 122 percent by the end of 2026, up 48 percentage points from the pre-pandemic level, as highlighted by Morgan Stanley analysts.

This rising debt burden poses challenges to Beijing’s efforts to stimulate domestic consumption, particularly in the wake of a prolonged slowdown in the property sector, which has weakened household balance sheets and local government revenues. Economic growth slowed to 4.3 percent in the second quarter, falling short of the official target range of 4.5 to 5 percent, amid declining retail sales and significant drops in fixed-asset investment.

To address these challenges, Chinese authorities recently unveiled stimulus measures including mortgage interest subsidies and reductions in the interest rate on a key funding facility. These actions came shortly after the State Council urged intensified efforts to apply "countercyclical adjustments" in macroeconomic policies. Additionally, the government has stepped up tax collection on income from offshore trusts.

However, skepticism remains regarding the overall effectiveness of these measures. Barclays described them as “a nudge, not a game-changer,” while Goldman Sachs estimated their fiscal impact at a modest subsidy of up to 100 billion yuan over five years. John Lam, UBS’s head of China and Hong Kong property research, warned that the policies might fail to meet investor expectations, citing constraints such as a 1.5 million yuan cap on housing values.

Some economists suggest that more decisive stimulus could be financed through increased bond issuance by the central government, which is viewed as less leveraged than local administrations. The central government currently runs a fiscal deficit of about 4 percent of GDP, while broader state expenditures push the augmented deficit closer to 10 percent, according to Goldman Sachs.

Compounding the fiscal strain, Beijing has had to increase revenue transfers to local governments, which traditionally depended on land sales to fund growth. The Washington-based Center for Strategic and International Studies noted that spending on debt interest climbed by 341 percent between 2013 and 2025, outpacing all other major budget categories.

As China navigates these fiscal constraints, observers highlight the complex balance authorities face in maintaining growth momentum while managing a rising debt load that increasingly limits the scope of expansionary policies.
