China's GDP growth may still be strong by global standards, but the annualized rate of 6 percent in the third quarter of 2019 is the lowest the country has recorded since 1992. In fact, China's GDP growth has been slowing steadily since the first quarter of 2010, when it exceeded 12 percent year-on-year. This downward trend is riskier than many observers seem to realize.

In recent years, the prospect of slower Chinese growth has gained widespread acceptance, both within and outside China. A shrinking working-age population means that 8 percent growth is no longer essential for full employment, it is argued, so introducing more fiscal or monetary stimulus isn't worth the risk. Instead, China's policymakers should focus on improving the quality of growth through supply-side structural reforms－an objective that, most economists in China argue, may in fact be easier to achieve in a lower-growth environment.

This approach is misguided. While structural adjustment is crucial, slower economic growth is not a prerequisite for success. On the contrary, it would impede reform. Moreover, given that the complexity of China's labor market impedes data collection, it is likely that China's employment situation is not as strong as many believe.

In this context, the government's top priority should be to arrest the decline in GDP growth－not least to prevent a kind of snowball effect that will make restoring growth far more difficult later. After nearly a decade of continuous slowing growth rate, investors and consumers are becoming increasingly reluctant to spend. Serious financial vulnerabilities will only deepen their concerns; ceteris paribus, declining growth will worsen all indicators of financial stability.

Fortunately, China has the policy space to pursue stimulus. To be sure, as a share of GDP, China's broad money supply (M2) is among the world's highest. The country's fiscal position may not be as strong as official figures suggest, and its corporate debt-to-GDP ratio is also among the highest in the world. But a closer look suggests that the associated risks are overblown.

The primary risk associated with monetary expansion is, of course, inflation. But US economist Milton Friedman's assertion in 1956 that "inflation is always and everywhere a monetary phenomenon" has been thoroughly debunked in recent years. Countries with high M2-to-GDP ratios have often maintained low inflation, and countries with low M2-to-GDP ratios have sometimes struggled with high inflation.

China is no exception. Although M2 has grown faster than nominal GDP consistently over the last decade, China's core consumer price index has hovered around 2 percent, and its producer price index has often fallen into negative territory. This can be explained partly by Chinese households' financial habits: they save a lot, boosting M2, but mostly in savings accounts, which aren't inflationary. For China, deflation is now a more serious concern than inflation.

On the fiscal front, the figures are doubly deceiving. Officially, China has had an average deficit-to-GDP ratio of less than 2 percent over the past decade, and a government debt-to-GDP ratio of about 40 percent. Yet in the first 10 months of this year alone, local governments have issued 2.53 trillion yuan ($359 billion) in special-purpose bonds, intended to support public interest projects.

Such bonds are not recorded as deficit financing, because it is assumed that the projects they fund will generate enough income to cover all debt obligations. If they were, China's deficit and debt ratios would rise significantly.

But even if these indicators were recalculated to account for all of the government's contingent liabilities, China's fiscal position would remain significantly stronger than those of most developed economies. More important, China's government boasted net assets worth some $17 trillion in 2016, according to the Chinese Academy of Social Sciences－a powerful buffer against fiscal shocks.

The bigger risks arise from China's corporate debt, which surpassed 160 percent of GDP in 2017. But even here, there is little reason to panic, as China's corporate debts－largely the result of underdeveloped share markets－are financed mostly by domestic savings. (Despite having increased in recent years, China's foreign debt remains relatively low.)

Moreover, the growth of China's corporate debt-to-GDP ratio has slowed in recent years. The best way to bolster this trend is not to refuse to roll over corporate debts－potentially causing liquidity shortages that drive companies needlessly into bankruptcy－but rather to give companies the chance to grow out of debt. That requires a faster-growing economy.

China has the policy space to implement a powerful economic stimulus package. While the side effects and limits of such a package should be fully recognized, the risks of a continued slowdown－not only for China, but also for a global economy primed for recession－dictate that the government should use it.
