HMM: China’s rapidly dwindling future will shape the world for decades to come.

The clearest sign of this diminishment is China’s worsening deflation problem. While Americans are worried about inflation, or prices rising too fast, policymakers in Beijing are fretting because prices are falling. The consumer price index has declined for the past three months, the longest deflationary streak since 2009. In the race for global economic supremacy, deflation is an albatross around Beijing’s neck. It’s a sign that the Chinese economic model has well and truly run out of juice and that a painful restructuring is required. But beyond the financial problems, the sinking prices are a sign of a deeper malaise gripping the Chinese people.

“China’s deflation is the deflation of hope, the deflation of optimism. It’s a psychological funk,” Minxin Pei, a professor of political science at Claremont McKenna College, told me.

The fallout won’t be contained to China’s shores. Because the country’s growth sent money stampeding around the globe over the past few decades, its contractions are creating a seesaw effect in global markets. The foreign investors who helped to power China’s rise are running to avoid catching the funk on their balance sheets, and governments the world over are starting to question the narrative of China, the dauphin. What Beijing does — or fails to do — to fight this malaise will determine the course of humanity for decades to come.

Deflation traps are difficult to get out of, and doubly painful for a country with as much indebtedness as China has.
