National copper social inventory posts YoY double decline, regional trends diverge [SMM Weekly Data]

SMM August 27:

Data Summary: As of Thursday, August 27, SMM copper inventories in major regions nationwide decreased by 24,900 mt WoW to 109,500 mt, while total inventories declined by 17,600 mt YoY from 127,100 mt in the same period last year.

In detail, in Shanghai, increased arrivals of domestic goods drove a slight inventory accumulation; in Jiangsu, narrowed arrivals of domestic goods and resilient downstream consumption supported continued destocking; in Guangdong, previously weak consumption gradually recovered as copper prices rebounded, with downstream demand recovering, warehouse withdrawals increasing, and inventories declining continuously.

Outlook: Supply side, domestic copper cathode arrivals are expected to tighten in the short term, while imported supplies remain stable, with overall supply marginally tight. Demand side, after previous persistent weakness, downstream users are releasing pent-up orders near month-end, with restocking interest rebounding. Current spot cargo availability is stable overall, and market trading sentiment is recovering. Based on supply-demand fundamentals, national copper social inventories are expected to continue their modest destocking trend next week.

DRC Signs 30-Year Dilolo–Sakania Railway Concession to Advance Lobito Corridor
The Democratic Republic of Congo has signed a 30-year concession agreement with Mota-Engil Africa for the Dilolo–Sakania railway, marking a major step in the development of the Congolese section of the Lobito Corridor. The agreement was signed on August 26 in the presence of DRC President Félix Tshisekedi and Angolan President João Lourenço. The 1,004.5-km railway serves Kolwezi, Tenke and Lubumbashi before connecting with the Angolan rail network leading to the Atlantic port of Lobito.​ According to the DRC Presidency, rehabilitation, modernization, extension, operation and maintenance of the railway will require indicative investment of approximately US$1.258 billion. Under the concession structure, the DRC will hold at least a 10% stake in the project company and receive a royalty equivalent to 7.5% of annual gross revenue. Financing and traffic-related risks will be borne by the concessionaire, without a sovereign guarantee, operating subsidy or minimum-revenue guarantee from the Congolese government.​ The railway is expected to support the movement of minerals, agricultural products, industrial inputs, hydrocarbons and other freight, while improving transport connectivity between the DRC and Angola. The two governments also agreed to work toward smoother rail operations between Sakania, Lubumbashi, Kolwezi, Dilolo, Luau and Lobito, including coordinated maintenance, greater tariff transparency and improvements at the Dilolo–Luau border crossing. The DRC government said the project is intended to lower logistics costs while supporting domestic production, processing and value creation rather than functioning solely as a raw-material export route.​ The concession is particularly significant for the copper industry because the railway directly serves Kolwezi, Tenke and Lubumbashi, key centres of the DRC Copperbelt. Rehabilitation of the route could provide copper and cobalt producers with an additional Atlantic export corridor and improve logistics flexibility relative to existing southern and eastern routes. However, the impact on actual copper flows will depend on the pace of rehabilitation, capacity additions and the eventual commercial terms offered to mining companies once the upgraded railway becomes operational.
