China reopens, and the world gets a new inflation problem

The western narrative that China's eventual retreat from zero-Covid would deliver an unalloyed disinflationary impulse to the global economy is about to collide with industrial reality. While financial markets celebrate the prospective elimination of factory bottlenecks and port congestion, they have systematically underpriced the reciprocal demand shock. When a $17-trillion economy reignites domestic mobility and industrial throughput, it does not simply export cheaper manufactured goods; it aggressively consumes marginal global energy, industrial metals, and agricultural foodstuffs.

The People's Bank of China signaled the policy pivot by cutting the reserve requirement ratio by 25 basis points on 25 November, injecting liquidity into a credit system eager to underwrite recovery. But the mechanical trade-off is stark: goods deflation in traded consumer electronics will be violently offset by commodity reflation across global upstream supply chains.

The Commodity Drain

During the lockdowns of 2022, China’s depressed domestic appetite freed up liquefied natural gas cargoes and dampened crude demand, inadvertently helping Europe weather its acute terms-of-trade crisis. A re-emergent Chinese aviation and logistics sector swiftly reverses that slack. If Chinese oil demand rebounds by even a modest one million barrels per day, the global spare capacity buffer held by OPEC+ evaporates, transforming a tenuous energy truce into an immediate bidding war.

Furthermore, copper, iron ore, and industrial chemicals respond not to headline GDP growth, but to raw infrastructure throughput and property completions. Even an incomplete property rescue package demands substantial physical inputs, placing an immediate floor under global industrial raw material prices just as Western central banks attempt to engineer demand destruction.

Central Banking Across Borders

This dynamic creates an uncomfortable dilemma for the Federal Reserve and the European Central Bank. Domestic interest rate tightening is designed to suppress interest-sensitive consumption at home, but it cannot dampen the marginal propensity to consume copper or crude in Guangdong.

If global commodity prices rebound while headline goods deflation stalls, headline inflation will prove exasperatingly sticky. The uncomfortable truth for developed-market central bankers is that Beijing’s reopening exports headline inflation to trading partners long before it restores supply-chain stability.
