Chinese factory activity returns to growth in September as AI demand boosts output

# What happened

# The numbers that matter

• Official manufacturing PMI: 50.1 (August: 49.8)

• Official non-manufacturing PMI (services and construction): 50.2 (August: 49.0)

# Why activity rose now Resumption of factory operations after weather disruptions and a marked global upswing in demand for AI-related products are the immediate drivers. Manufacturers linked to AI hardware and data-center capacity are booking higher orders, which lifted production and new orders in September. That boost is concentrated in sectors supplying AI infrastructure rather than broad-based consumer demand.

# Policy response and recent measures Beijing has moved to direct cheaper credit toward priority areas. New measures aim to channel lower-cost funding into infrastructure and technology and expand support for home buyers. Officials have signaled a willingness to accelerate fiscal spending and introduce timely policies to support growth if needed.

# Where recovery is uneven

# Risks and external factors

• Property slump: Ongoing weakness in real estate lowers consumption and investment prospects.
• Geopolitical and trade frictions: Increased scrutiny of Chinese goods abroad and changing tariffs create uncertainty for exporters.
• Concentrated demand: Growth tied to AI hardware could create sectoral imbalances if global AI investment slows or shifts.

# Near-term outlook The September PMI readings suggest a modest uptick in industrial momentum, but the indexes sit close to the 50 line. Continued gains will depend on whether policy measures translate into broader credit flows and whether relief in the property sector can improve household finances and consumption. Officials' stated intent to step up fiscal and policy support indicates a bias toward more stimulus if growth weakens.

# What this means for markets and commodities Stronger factory activity supports demand for industrial inputs such as metals, energy and components used in AI servers and data centers. A sustained expansion would be positive for commodity-linked industries and China-sensitive assets, while persistent domestic weakness would keep pressure on consumer-facing sectors.

# Bottom line September's PMI readings show China's factories moving back into marginal growth, driven largely by AI-related demand and resumed operations. The improvement is meaningful but narrow, leaving the overall recovery vulnerable to the property downturn, weak domestic demand, and external trade risks.
