SMM News, March 5:

Data Brief: As of Thursday, March 12, SMM copper inventories in major regions nationwide fell 0.57% WoW from last Thursday, ending the inventory buildup seen over the previous three consecutive weeks; total inventories increased 218,400 mt YoY from the same period last year, while regional performance remained differentiated.

By region, copper cathode inventory in Shanghai continued to build up. Although consumption recovered somewhat, inventories still trended upward due to the impact of concentrated arrivals of imported cargoes and delivery factors; in Jiangsu, inventories declined slightly, supported by recovering downstream consumption; in Guangdong, consumption rebounded significantly and warehouse withdrawals increased, with inventories already reaching an inflection point and expected to continue declining going forward.

Looking ahead, on the supply side, imported cargoes continued to arrive at port and domestic arrivals remained steady; on the demand side, downstream enterprises fully resumed production, and consumption recovered markedly. Based on the overall supply-demand pattern, supply is expected to remain normal next week while consumption steadily rebounds, and weekly copper cathode inventories are expected to destock somewhat.

High Copper Prices Suppress Consumption Expectations, Shanghai Spot Copper Premiums Under Pressure After Contract Rollover [SMM Shanghai Spot Copper]

[SMM Shanghai Spot Copper] Looking ahead to tomorrow, from the perspective of supplier behavior, wait-and-see sentiment was strong in the early session, with notable divergence in offers; subsequently, some suppliers chose to offload inventory, mainly considering that downstream consumption expectations weakened after sustained copper price increases, upside room for spot premiums was limited, and willingness to liquidate holdings strengthened, driving the overall premiums center downward. Supply side, attention should be paid to the outflow of unmatched warrants after the contract rollover; if warrants are released in a concentrated manner, this will further suppress spot premiums. Inventory side, SMM recorded social inventory of 282,800 mt, down 17,000 mt from Monday, with the destocking pace showing a slowdown compared to the earlier period. Overall, under the combined effects of strengthened willingness to sell among suppliers and weakened consumption expectations, coupled with warrant outflows, spot prices against the 2605 contract are expected to see a slight decline in premiums tomorrow.
