SMM News, March 19:

Data Brief: As of Thursday, March 19, copper inventories in SMM's major regions nationwide fell 8.85% WoW from last Thursday, while total inventories increased 176,700 mt YoY from the same period last year, with all regions posting destocking.

By region, copper cathode inventories in Shanghai continued to decline, as arrivals of domestic material gradually decreased after the end of delivery, while warehouse withdrawals gradually exceeded warehouse inflows amid consumption support; in Jiangsu, inventories also continued to destock, as demand in northern China recovered, arrivals of domestic material decreased, and local consumption rebounded; in Guangdong, inventories also trended downward, supported by a marked recovery in downstream demand and slightly tighter supply.

Looking ahead, on the supply side, imported material continued to arrive at ports, but arrivals of domestic material decreased due to the end of delivery; on the demand side, the sharp pullback in copper prices clearly stimulated downstream procurement. Based on the overall supply-demand pattern, supply is expected to remain tight next week while consumption steadily rebounds, and weekly copper cathode inventories are expected to continue destocking.

According to data released by the SHFE on March 19, copper warrants saw significant declines across major regions, with total inventory dropping by 12,244 tons from the previous trading day, marking a substantial drawdown. Copper prices continued their downward trend during the day, with the trading range dipping to 94,000-95,800 yuan per ton. The price drop stimulated downstream companies' enthusiasm for buying on dips, pushing the spot premium/discount center upward. Taking advantage of the rebounding premiums, holders actively shipped their warrants, leading to a large outflow of inventory that was subsequently absorbed by downstream consumers. This indicates that current price levels have become increasingly attractive to end-users.
