[Shanghai Spot Copper] For tomorrow, Shanghai spot copper discounts are expected to continue a modest recovery trend, but the room for improvement is limited. During the second trading session of the day, spot premiums and discounts for SHFE copper gradually stabilized, with suppliers making no significant price adjustments.

Meanwhile, downstream acceptance of current prices has been gradually improving, and buying and selling sentiment remains stable. In terms of market structure, the price spread between futures contracts for the next month narrowed slightly, suggesting that suppliers' willingness to ship to delivery warehouses may have decreased. On the supply side, domestic copper and previously locked-price imported sources continue to arrive, coupled with high social inventory, resulting in an overall ample supply of circulating goods. On the demand side, downstream enterprises are steadily resuming production, and buying and selling sentiment has rebounded MoM, but the overall pace of recovery remains slow, making it difficult to provide strong support for premiums and discounts. Overall, while spot premiums and discounts are slowly recovering, there are still upward resistance.
