How does weak domestic consumption translate into an exporter advantage?
Core argument: China's real effective exchange rate has fallen substantially since 2021, and the yuan is even weaker relative to trend than the raw depreciation data suggest, giving Chinese companies a large competitive advantage.
China’s saving remains very high, but its investment is running into diminishing returns in the face of slowing technological progress and a shrinking working-age population. Yet the Chinese government keeps failing to take effective steps to reduce savings and increase consumer demand. But exports and imports are the consequence of decisions at the level of companies and individuals. So how does China’s underconsumption problem translate into incentives for exporters and importers? China’s real effective exchange rate has fallen substantially — the yuan has “depreciated” — since 2021. But this understates the yuan’s true level of weakness. The yuan is even weaker relative to trend than its raw depreciation data would suggest. This gives Chinese companies a large competitive advantage. And the value of the yuan is basically set by the Chinese government. The manipulation of the yuan by the Chinese government is unique. Nothing similar occurs with other major currencies. These days the Chinese government manipulates its currency largely by having state banks rather than the government proper buy dollars. These purchases don’t show up in official reserves, so doing it this way hides the extent of the weak-yuan policy from casual observers.
