China's domestic commodity futures closed mixed at midday on July 30, with lithium carbonate and iron ore each falling more than 3% while SC crude oil surged more than 6% and ethylene glycol rose nearly 5%.
The divergence between energy-linked contracts (crude, EG, fuel oil, PTA) and industrial/battery materials (lithium carbonate, iron ore) reflects differing demand narratives: lithium carbonate's decline of more than 3% is directly relevant to LME lithium and the broader battery supply chain, as Chinese domestic futures serve as a key price reference for global lithium pricing; meanwhile, the crude-oil-linked complex rising more than 6% (SC crude) signals a separate energy-sector demand or supply dynamic that flows into petrochemical feedstocks (EG, PTA, fuel oil).
