SHFE/LME price ratio declines with limited offers and bids, morning market quiet [SMM Yangshan spot copper]

Published: Sep 21, 2026 13:25

On September 21, the average warrant price fell by $5/mt from the previous trading day to $119/mt (price range: $114-124/mt); the average B/L price fell by $3/mt from the previous trading day to $113/mt (price range: $106-120/mt); the average EQ copper (CIF B/L) price fell by $10/mt from the previous trading day to $55/mt (price range: $50-60/mt), with quotations referencing cargoes arriving from September to mid-to-late October.

Today, the SHFE/LME price ratio declined significantly into inversion, and market demand was sluggish. Meanwhile, domestic copper cathode social inventory continued to decline, and domestic spot premiums rose to high levels. Suppliers were reluctant to sell at low prices, with few bids and offers in early trading, leaving the market relatively quiet. Today, mainstream quotations for registered ER copper warrants were heard at $120-130/mt; mainstream quotations for registered ER copper B/L arriving in late September were around $120/mt; mainstream quotations for EQ copper arriving in October were at $60-70/mt.

[SMM Shanghai Spot Copper] Looking ahead to tomorrow, SMM recorded social inventory in Shanghai at 43,900 mt, down 14,700 mt MoM; social inventory in Jiangsu stood at 20,600 mt, down 200 mt MoM. Trading performance was relatively strong last Thursday and Friday, with downstream processing enterprises picking up goods as usual, while limited inbound supply replenished warehouses, driving a notable decline in Shanghai inventory and keeping available cargoes in the market persistently tight. Although some imported copper arrived successively, most of it flowed directly to downstream processing enterprises and did not enter warehouse statistics. Meanwhile, as the Mid-Autumn Festival and National Day holidays approach, some downstream enterprises have begun pre-holiday stockpiling, further boosting spot procurement demand. Overall, supported by low inventory, tight availability of cargoes, and pre-holiday stockpiling demand, Shanghai spot premiums are expected to have room to edge up slightly tomorrow.
