What moved
Trafigura and traders delivered 20,000 tons of copper into LME warehouses; the cash-to-three-month spread collapsed to $248-a-ton backwardation from $545 on Monday, ending the squeeze.
The market transmission
The delivery broke acute physical tightness in London copper. Backwardation at this width had priced a real shortage of deliverable metal; the sudden build signals either improved supply or deliberate liquidation of a positioning squeeze. The spread compression is the market signal itself: it moves from scarcity pricing to contango or near-parity, which reshapes carry incentives and storage economics. If deliveries continue as traders expect, near-term physical tension eases and the squeeze premium unwinds further.
What would change this
Backwardation collapse is not the same as a price collapse. The three-month price itself may rise or hold steady while the spread tightens; the repricing is in the curve, not necessarily in the outright level. The delivery may reflect supply improvement, or it may reflect traders exiting long positions that had crowded into the physical market. Both move the spread the same way but with different medium-term implications for price discovery.
