[SMM Copper Morning Meeting Summary] News:

(1) On December 15, the London Metal Exchange (LME) announced plans to introduce new position limit rules starting from July 6, 2026, in response to the UK Financial Conduct Authority (FCA) requirement, transferring the authority for setting and managing position limits on commodity derivatives from the regulator to the exchange itself. The new rules will apply to key metals such as aluminum, copper, lead, nickel, tin, and zinc, and related contracts, with limits set on net positions at both the entity and group levels. The LME will release a consultation paper in February 2026, inviting feedback from market participants.

Overall, long-term contract negotiations are intense, and the spot order market is chaotic, with poor actual transaction conditions.

According to an SMM survey, as copper prices continued to weaken, transactions in the secondary copper rod market recovered. After traders profited from futures arbitrage, their cargo pick-up speed accelerated. Secondary copper rod enterprises indicated that downstream demand still showed no significant improvement.

(5) Inventories: On December 15, LME copper cathode inventories increased by 725 mt to 166,600 mt. On December 16, SHFE warrant inventories increased by 3,558 mt to 45,784 mt.

Prices: On the macro front, US non-farm payroll growth in November was stronger than expected, but the unemployment rate rose to 4.6%, a four-year high, indicating mixed signals from the job market. Additionally, uncertainty over the US Fed Chairman appointment intensified, adding variables to the future policy path. On the fundamentals side, supply side, effective market supply was sufficient, and suppliers were active in selling, but their willingness to sell is expected to weaken after delivery. Demand side, despite the pullback in copper prices, downstream purchasing remained cautious due to high price suppression, and overall demand performance was weak. Overall, copper prices are expected to remain supported today.
