On the macro front, Iran said mediators proposed a 10-day US-Iran ceasefire to resume implementation of the memorandum of understanding, and it has received the proposal and indicated it may negotiate with the US based on national interests. The Houthis announced a maritime ban against Saudi Arabia, and Saudi Arabia said it is taking military action to ensure shipping safety in the Bab el-Mandeb Strait. US media reported that Trump is focused on making Iran "pay a price," but negotiations between the two countries continue. On the fundamentals side, supply side, available spot resources in China remained acutely tight, social inventory stayed at a low for the year, arrivals from cross-regional transfers were limited, and the tight spot situation is unlikely to ease in the short term. Demand side, the industry was in the traditional consumption off-season, downstream enterprises made sporadic need-to-basis purchases, and overall consumption was weak. Inventory side, as of Monday July 20, SMM copper inventories in major Chinese regions fell by 32,700 mt WoW to 107,300 mt. Continued destocking provided bottom support for copper prices. Overall, the tight supply and destocking trend continued, and copper prices are expected to drift higher today.
Jul 21, 2026 08:58[SMM Shanghai spot copper] Social inventory of copper cathode in Shanghai kept declining, and available spot cargoes tightened, which pushed the center of spot premiums steadily higher and hit a new high for the year. Meanwhile, the spot price spread between Shanghai and Guangdong widened further, opening the window for cross-regional transfers. According to SMM, some suppliers have already initiated cargo transfers from Guangdong to Shanghai, and the shipped copper cathode is expected to arrive in the Shanghai market this week.
Jul 20, 2026 10:46SMM April 30 update: Guangdong region: Premiums in this region trended higher with fluctuations this week, mainly due to fluctuating inventory declines combined with suppliers insisting on high-premium shipments. As of Thursday, high-quality copper was quoted at 320 yuan/mt, up 30 yuan/mt WoW; standard-quality copper was quoted at a premium of 240 yuan/mt, up 30 yuan/mt WoW; SX-EW copper was quoted at 180 yuan/mt, up 30 yuan/mt WoW. On Thursday, the price spread of standard-quality copper premiums between Shanghai and Guangdong showed Guangdong higher by 210 yuan/mt. Given the large price spread, cross-regional transfers occurred this week, with some northern sources moving south early in the week, though the total volume was not large. According to SMM statistics, as of Thursday, total inventory in Guangdong warehouses was 13,700 mt, down 1,300 mt WoW, with the decline showing a slowdown. Warrants totaled 5,200 mt, down 302 mt WoW. Specifically: warehouse arrivals this week were 12,100 mt/week, up 4,600 mt/week WoW, well below the annual average (14,000 mt/week), mainly due to increased northern sources. Warehouse withdrawals were 13,400 mt/week, down 2,400 mt/week WoW, slightly below the annual average (14,200 mt/week), as many copper processing enterprises planned 3-4 days off during the Labour Day holiday, leading to reduced pre-holiday restocking. Looking ahead to next week, as downstream factories will be on extended holidays during Labour Day, suppliers are expected to prioritize sending cargo to warehouses. Warehouse inventory is expected to increase after the holiday, and spot premiums are unlikely to rise.

Apr 28, 2026 09:04![Widening Guangdong-Shanghai Aluminum Price Spread Opens Arbitrage Room for Cross-Regional Flows [SMM Analysis]](https://imgqn.smm.cn/production/admin/votes/imagesqsDLb20240416161800.jpeg)
As of April 24, the mainstream price in the south China market — SMM A00 aluminum (Foshan) was at a discount of 345 yuan/mt against the 2605 contract, while the mainstream price in the east China market — SMM A00 aluminum was at a discount of 130 yuan/mt against the 2605 contract. The price spread between the two regions had exceeded 200 yuan/mt, covering sea freight, short-haul transfer, and logistics costs, officially opening up the transshipment window between Guangdong and Shanghai...
Apr 26, 2026 23:31[SMM Shanghai Spot Copper] Looking ahead to tomorrow, from the perspective of regional price spreads, the intraday Shanghai-Guangdong price spread widened further compared to yesterday, reaching 200 yuan/mt, with the theoretical arbitrage window now open. According to SMM, some suppliers have already begun relocating cargo from Shanghai warehouses to the Guangdong region to capture regional price spread gains. If spot premiums in Guangdong continue to remain strong, cross-regional cargo transfers will effectively divert available cargo from the Shanghai market, potentially providing marginal support for local spot discounts or even boosting spot premiums in Shanghai and other regions. Demand side, after consecutive declines in copper prices, downstream procurement sentiment recovered slightly, but overall purchasing remained dominated by rigid demand. Overall, under the combined effects of cross-regional arbitrage diversion and support from the inter-month price spread structure, Shanghai spot copper is expected to maintain a discount against the 2605 contract tomorrow. Going forward, attention should be paid to the transmission effect of Guangdong premiums on the east China market.
