Copper prices have climbed for four straight days, hitting $14,521 per metric tonne on the London Metal Exchange. The 2 percent weekly gain is supported by resilient demand in China and declining inventories in major warehouses.
Why it matters
Tight scrap supply and falling warehouse stocks are fueling market volatility as buyers compete for imported metal. Investors are closely monitoring the shifting strength of the yuan and upcoming trade policy discussions between the US and China.
Three-month copper on the London Metal Exchange reached $14,521 per tonne, supported by a 72 percent rise in the Yangshan premium to $124 per ton. LME warehouse stocks fell to 139,650 tonnes while COMEX inventories remained at 696,631 tons.

Market Dynamics
This rally reflects broader macroeconomic cycles where industrial demand in manufacturing hubs often outpaces available exchange inventories. The current environment follows patterns established during the 2026 copper price peak, signaling ongoing tightness in global commodity supplies.
Retail investors holding commodity-linked assets should anticipate continued price volatility as inventory levels remain compressed. The strengthening of the yuan could further complicate portfolio allocations for those with exposure to cross-border industrial trade.
The takeaway
Tight supply in Chinese markets continues to drive up global copper prices despite a surplus of inventory in North American warehouses. Readers should monitor upcoming diplomatic meetings for potential changes to trade tariffs that could stabilize or shift current metal valuations.
What happens next
The White House is expected to release a decision regarding tariffs on refined copper, which will likely impact market pricing and import strategies for international buyers.
