China’s inflation data for August indicates the country is moving further into deflation. The Consumer Price Index (CPI) decreased by 0.4% year-over-year, missing the expected drop of 0.2% and contrasting with a previous stable reading of 0.0%. The month-on-month CPI remained unchanged, despite expectations of a 0.1% increase, following a 0.4% rise in July.
Producer Price Index and Involution
The Producer Price Index (PPI) fell by 2.9% year-over-year, aligning with expectations but slightly improving from the prior 3.6% drop. The PPI was flat on a month-on-month basis. Efforts to combat involution—where excessive competition hampers progress—continue to face obstacles. This concept of involution, especially prevalent in sectors like solar, electric vehicles, and steel, is part of a broader policy shift initiated in July under President Xi Jinping’s guidance. The challenge remains substantial due to widespread overcapacity in competitive private-sector industries.
With China moving further into deflation, the August consumer price data at -0.4% confirms that domestic demand remains very weak. This trend continues despite the government’s stimulus efforts, which are not gaining traction. For us, this reinforces a bearish view on assets tied to Chinese consumption and the broader domestic economy.
We anticipate the People’s Bank of China will have to implement more significant easing, likely through further rate cuts in the coming weeks. We have already seen the PBOC cut its key lending rates multiple times in 2025, widening the policy gap with the U.S. Federal Reserve. This divergence will continue to weigh on the yuan, making it logical to hold positions that benefit from a weaker currency, such as buying USD/CNY call options.
The producer price index, falling at an annual rate of 2.9%, signals that industrial overcapacity is still a major issue. This is bad news for global commodities that depend on Chinese industrial activity. We see continued weakness in iron ore, which has already fallen over 12% in the last quarter, and are considering put options on copper and other base metals.
Market Implications and Comparisons
This economic weakness is a significant headwind for Chinese stock markets, so buying puts on China-focused ETFs like the FXI remains a viable strategy. Uncertainty about the effectiveness of future stimulus is pushing up volatility, with the Hang Seng implied volatility index now trading near its 12-month highs. This environment makes option strategies more appealing as big price swings are expected.
The current situation is starting to look a lot like Japan’s “lost decade” which began in the 1990s, characterized by persistent deflation and stagnant growth. If this pattern holds, we might be looking at a prolonged period of low performance for Chinese equities. This long-term outlook supports strategies that profit from a slow grind down or sideways movement in the market over many months.
