SMM News, March 23:

Data brief: As of Monday, March 23, SMM copper inventories in major regions nationwide fell 14.54% WoW from last Monday, with all regions posting significant destocking.

Specifically, in Shanghai, the arrival pace of imported and domestic supplies remained normal, while downstream consumption continued to recover on the back of the pullback in copper prices, leading to notable inventory drawdowns; in Jiangsu, downstream consumption also improved significantly amid the sharp pullback in copper prices; in Guangdong, downstream consumption remained highly buoyant, and together with tighter supply, spot inventory dropped sharply.

Looking ahead, arrivals of imported and domestic supplies are expected to remain stable, with the overall supply side tending to stabilize; on the demand side, the continued pullback in copper prices will further stimulate downstream procurement demand, and rigid demand is expected to continue to be released. According to survey data, the weekly operating rate of copper cathode rod is expected to rise to 83.76% this week, up 2.25 percentage points WoW. Considering both supply and demand, the market has currently formed a pattern of “stabilizing supply and continued recovery in consumption,” and social inventory is expected to continue destocking this week.

In addition, persistently high raw material costs clearly suppressed import demand. In terms of operating conditions, the pace of work resumption in the brass billet industry after Chinese New Year was also noticeably slower than in previous years.
