The one-month premium reached its widest level since the 2021 squeeze, signaling acute demand for immediately available metal in the London market.
A sharp tightening in the copper market pushed the London Metal Exchange's front-month spread to a $370-per-ton premium on Friday, the widest one-month spread since the 2021 supply squeeze. The move indicates traders are willing to pay an unusually large premium for copper that can be delivered in the near term, a classic sign of immediate supply stress in the physical market.
