SMM News, March 27:

Data Brief:

As of Thursday, March 26, SMM copper inventories in major regions across China fell 18.29% WoW from last Thursday. Total inventory increased 92,900 mt YoY and has posted destocking for two consecutive weeks.

By region, in Shanghai, copper cathode inventory continued to pull back as downstream consumption boosted warehouse withdrawals well above warehouse inflows; in Jiangsu, downstream consumption recovered steadily, and inventory continued to decline in tandem; in Guangdong, consumption remained robust, coupled with tight supply in some areas, driving a faster pace of inventory decline.

Looking ahead, on the supply side, imported copper cargoes continued to arrive, while arrivals of domestically produced copper decreased somewhat; on the demand side, downstream enterprises mainly made just-in-time procurement. Based on the overall supply-demand pattern, China’s copper cathode supply is expected to remain tight next week, while consumption is expected to stay broadly stable, and weekly inventory is expected to continue destocking.
