SMM June 18 News:

Data Brief: As of Thursday, June 18, SMM's national mainstream copper inventories fell by 23,500 mt WoW to 194,300 mt, while total inventories increased by 48,400 mt compared to the 144,800 mt in the same period last year.

Specifically, arrivals of imported and domestic copper remained persistently low, sustaining the destocking trend. In Jiangsu, limited supply arrivals combined with faster downstream warehouse withdrawals drove inventory declines. In Guangdong, weak end-user stockpiling sentiment ahead of the Dragon Boat Festival led to a slight inventory buildup in the region.

Looking ahead, on the supply side, arrivals of imported and domestic copper are expected to remain tight in the near term. On the demand side, as the Dragon Boat Festival approaches, downstream enterprises show subdued stockpiling sentiment, with overall consumption remaining weak. The current spot market is characterized by tight supply and weak demand. It is expected that national copper social inventories will continue destocking next week.

Suppliers Both Hold Prices Firm and Make Adjustments, Shanghai Spot Copper Premiums Under Sustained Pressure

Looking ahead to next week, intraday copper prices edged down slightly, and alongside pre-stocking for the Dragon Boat Festival, downstream dip-buying sentiment recovered somewhat, with purchase and sales sentiment each up 0.04 WoW, while transactions for low-priced sources were moderate. However, suppliers’ morning quotes were firm, with standard-quality copper at parity to a premium of 30 yuan/mt, then continuously lowered to near parity. In the second session, some brands were quoted at a discount of 20 yuan/mt, reflecting that amid the current copper price decline, suppliers' willingness to sell increased, while downstream willingness to chase higher prices was insufficient, leaving overall transactions muted. Overall, constrained by high copper prices, Shanghai spot copper premiums against the 2607 contract are expected to hold at current levels next week, or edge up slightly.

[SMM Shanghai spot copper] Next week, with intraday copper prices edging down and combined with pre-holiday restocking ahead of the Dragon Boat Festival, downstream dip-buying sentiment recovered somewhat. Purchase and sales sentiment rose 0.04 WoW respectively, with moderate transactions for low-priced cargoes. However, suppliers' early-session offers were firm, with standard-quality copper quoted from parity to a premium of 30 yuan/mt, subsequently adjusted down to near parity. In the second session, some brands were already quoted at a discount of 20 yuan/mt, reflecting that amid the current copper price decline, suppliers' willingness to sell increased, while downstream buyers' willingness to chase higher prices was insufficient. Overall trading was thin. On balance, pressured by high copper prices, Shanghai spot copper premiums against the SHFE 2607 contract are expected to remain at current levels next week or edge up slightly.
