Copper rose to around $14,340 a ton on the London Metal Exchange on Monday, still short of the all-time high above $14,500 set in September, extending a rally built on supply setbacks and tariff-driven trade dislocations that has already carried the metal more than 40 percent higher this year. CME copper closed at $6.64 a pound, up 2.3 percent on the day.
The buying is a demand bet placed into thin liquidity. China is closed for Golden Week until October 8, so the move came without mainland participation. Traders are wagering on Chinese restocking and an AI-capex cycle, a tech-led rally strong enough to override a 5.31 percent 10-year Treasury yield. Causation is primarily positioning and holiday-thinned flows, with demand confirmation pending.
The cross-benchmark gap remains wide: $6.64 a pound implies roughly $14,640 a tonne, against the LME print near $14,340. The dislocation traces to the year’s US tariff confusion, which pulled copper toward American warehouses as traders arbitraged the policy, straining supply for buyers elsewhere. Mine disruptions in Africa, Chile and Indonesia have left the physical market with little buffer.
If Shanghai reopens October 8 and confirms the bid, the move is fundamentally validated. If not, it was positioning into an empty room. The October 9 CFTC positioning data will show whether speculators were already long into the rally.
