Is China's campaign against excess capacity reflating manufacturing prices?
Core argument: Industry-level Chinese data show an R² of 0.43 between 2025 declines in fixed asset investment and Jan–Feb 2026 increases in producer prices, with a few outliers, according to the authors' analysis.
To gain confidence in the idea that the anti-involution campaign has contributed to a) the decline in fixed asset investment and, thereby, b) the increase in manufacturing PPI, we examined the correlation between industry-level investment trends in 2025 and PPI in Jan-Feb 2026. Except for a few outliers, there is a respectable relationship (R2 = 0.43) between investment and PPI: the industries that saw the largest declines in investment in 2025 are also those that have seen the largest increases in PPI in Jan-Feb 2026. This makes us rather confident in the hypothesized mechanism: the anti-involution campaign -> decline in fixed asset investment -> decline in excess capacity -> increase in manufacturing PPI. If durable, China’s reflation will have global repercussions, most directly via export prices, even if the precise impact is difficult to quantify. This contrasts with the common view outside China that US tariffs will lead to excess supply being dumped into other markets, putting downward pressure on global prices.
