Guangdong region: This week, premiums in the region trended higher amid choppy trade, mainly driven by a rapid drop in inventory (not due to consumption but because metal was transferred to east China). As of Thursday, high-quality copper was quoted at 200 yuan/mt, up 20 yuan/mt from last Thursday; standard-quality copper premiums stood at 140 yuan/mt, up 40 yuan/mt from last Thursday; and SX-EW copper premiums were at 80 yuan/mt, up 40 yuan/mt from last Thursday. On Thursday, the Shanghai-Guangdong price spread for standard-quality copper premiums stood at 350 yuan/mt in favor of Shanghai. The wide spread prompted inter-regional shipments this week. According to SMM data, as of Thursday, total inventories in Guangdong warehouses stood at 15,200 mt, down 7,500 mt from last Thursday, while warrant holdings totaled 4,100 mt, down 600 mt from last Thursday. In detail: Weekly arrivals reached 14,900 mt/week, up 800 mt/week WoW, slightly above the annual average (14,000 mt/week). Arrivals were relatively normal this week, with both domestic and imported copper arriving. Warehouse withdrawals amounted to 22,400 mt/week, up 6,700 mt/week WoW, significantly above the annual average (14,200 mt/week). The main reason was the wide Shanghai-Guangdong spread, which led to substantial cargo transfers from warehouses to the east China market, while local actual consumption was weak.

Looking ahead to next week, we understand that both imported and domestic copper will arrive normally. Consumption is expected to remain weak due to elevated copper prices, and the key focus will be whether inter-regional shipments persist. Inventories are likely to stay low, with little chance of a significant increase, and spot premiums are expected to remain at high levels.

DR Congo to Enforce Local Ownership Stakes for Foreign Miners from July 31 Amid Industry Concerns

The Democratic Republic of Congo will begin enforcing a long-delayed requirement for mining companies to offer local ownership stakes from July 31, according to foreign media reports. The decision comes despite concerns from major copper and cobalt producers regarding its potential operational and legal impact on the sector. The initiative stems from provisions in the country's 2018 Mining Code that mandate international mining operators transfer 10% of their equity to Congolese nationals, with 5% specifically designated for employees. To date, no major foreign mining operator has formally demonstrated compliance, citing unresolved questions regarding implementation and regulatory structures. According to foreign media reports, letters issued by Kinshasa instructed major international miners including Glencore, Ivanhoe Mines, CMOC, and Huayou Cobalt to submit proof of compliance by the end of July or face potential regulatory sanctions. The mines ministry reaffirmed this timeline following high-level discussions with mining executives regarding the final decree. Following the consultations, government officials and mining representatives agreed that the implementation decree will be signed after incorporating limited technical amendments. An ad hoc committee has been established to finalize these adjustments, which may include mechanisms such as interest-free loans or employee cooperatives to facilitate worker equity acquisition. The local equity mandate remains distinct from the state's existing 10% non-dilutable free-carry interest in mining assets. While specific sanctions for non-compliance after the July 31 deadline have not been publicly detailed, the enforcement push underscores broader regional efforts across the Central African Copperbelt to secure higher local value retention amid elevated global commodity demand.
