Specifically, Shanghai's inventory decreased by 7,700 mt WoW to 218,700 mt, as both imported and domestic copper arrivals were limited over the weekend, with some shipments redirected to South China. Jiangsu's inventory rose by 1,800 mt WoW to 59,600 mt, primarily due to increased arrivals and weakened consumption. Guangdong's inventory surged by 8,500 mt to 51,700 mt, driven by concentrated arrivals from east China and persistently weak consumption, as reflected by the low daily average outflows from warehouses. Looking ahead, recent imported copper arrivals are expected to remain limited, and domestic copper arrivals will also be scarce, indicating that supply will likely stay tight this week. On the consumption side, some downstream users are replenishing stocks ahead of the Qingming holiday. According to our survey, the weekly operating rate for refined copper rod reached 71.35%, up 7.29 percentage points WoW. Therefore, we anticipate a scenario of tight supply and increased consumption this week, leading to a renewed decline in inventories.
