AI Shows Up in China's Prices: Storage Devices Up 45%
Data storage devices cost 45.4% more in China in October than a year earlier, even as overall consumer inflation slowed to 0.7%, official data showed on November 9.
China's October inflation figures, published by the National Bureau of Statistics on Monday, November 9, look at first like a story about oil and pork. Consumer prices rose 0.7% from a year earlier, food fell 2.9% and gasoline rose 22.4%. One line stood out from the rest: data storage devices were 45.4% more expensive than a year earlier, and mobile phones 16.7%, according to the bureau's breakdown reported by Shanghai Metals Market.
Those are the prices where the AI build-out reaches households. Data centres for AI models need huge amounts of memory, chipmakers have shifted capacity towards the high-bandwidth memory those servers use, and the resulting shortage of ordinary memory chips has raised the cost of the drives, phones and computers that contain them. Earlier this month Qualcomm cited the memory squeeze as one reason its handset revenue fell, as phone makers absorbed higher component costs.
The producer data show the same pressure further up the chain. Factory-gate prices rose 5.7% from a year earlier, the fastest since June 2022, and prices in computer and electronics manufacturing rose 5.9%. Energy dominated the total, with coal mining up 36.6% and oil and gas extraction up 35.0%, but reports on the release also linked part of the increase to investment in the AI industry. Consumer goods prices at the factory gate fell 0.1%, so the pressure is concentrated in inputs and electronics.
Central bankers have been describing this effect for months. Federal Reserve Governor Lisa Cook said in September that part of the recent surge in prices of AI-related goods such as chips, computers and software reflected a shift in demand towards those sectors, which she expected to ease as supply adjusts, and that monetary policy's tools "are too blunt to target narrow sectors". China's figures suggest that adjustment has not happened yet.
For investors the numbers cut two ways. Rising memory prices support the revenue of memory makers even as AI stocks sell off, but they raise the cost of every device that has to be rebuilt around AI features. Last week's sell-off in memory names, including Micron's 17.5% fall on November 5, priced a slowdown in data-centre demand; the price data so far show a shortage, not a glut.
