China-linked commodity markets sent a mixed signal over the past week: raw materials tied to heavy industry remained relatively subdued, while copper strengthened sharply and oil retreated as global supply fears eased. The divergence reflects an uneven Chinese economy, with weak property-related demand continuing to weigh on steel consumption even as manufacturing, electrification and infrastructure support demand for industrial metals. At the same time, China remains central to global pricing: its steel sector dominates iron ore consumption, while its demand for copper and crude can amplify supply disruptions elsewhere.
Iron ore edged higher despite little evidence of a strong recovery in Chinese construction. The most-traded contract on the Dalian Commodity Exchange was at 720.5 RMB (US$107) per tonne on August 26, compared with 712.5 RMB (US$106) per tonne on August 19, a rise of 8 RMB, or 1.1%. Prices have been supported by continued mill buying, but the upside remains constrained. China’s July crude steel output fell 3.6% year-on-year, while construction demand remains weak because of the prolonged property downturn. At the same time, iron ore arrivals at Chinese ports jumped 65% week-on-week after weather-related disruption eased, adding to available supply. For major exporters such as Australia and Brazil, China’s subdued steel demand limits the scope for a sustained global iron ore rally.
Copper told a different story. Three-month copper on the London Metal Exchange rose to about US$14,363 per tonne on August 26 from US$13,890 on August 19, an increase of roughly US$473, or 3.4%. The move was driven less by a sudden Chinese demand surge than by distorted global supply flows: expectations of future US tariffs have drawn large quantities of copper into American warehouses, tightening availability elsewhere. Strong Chinese demand and Indonesian supply disruptions added support.
Oil moved in the opposite direction. ICE Brent settled at US$87.84 a barrel on August 26, down from US$91.62 on August 19, a fall of US$3.78, or 4.1%. Progress in Iran-Oman talks raised hopes that traffic through the Strait of Hormuz could improve, reducing the geopolitical premium built into prices. For China, the world’s largest crude importer, cheaper oil would ease import costs and pressure on refiners.
Overall, the week’s commodities picture points to weak Chinese property demand but continued strength in manufacturing-linked metals. The key questions are whether steel demand improves into the traditional autumn construction season and whether copper’s global supply squeeze persists.
