SMM June 11:

Guangdong: This week, spot premiums in the region sustained a rapid rebound, as reduced arrivals coupled with lower copper prices prompted suppliers to actively hold prices firm, lifting spot premiums sharply higher. As of Thursday, high-quality copper was quoted at 240 yuan/mt, up 210 yuan/mt from last Thursday; standard-quality copper was quoted at a premium of 180 yuan/mt, up 210 yuan/mt from last Thursday; and SX-EW copper was quoted at a premium of 120 yuan/mt, up 200 yuan/mt from last Thursday. On Thursday, the price spread of standard-quality copper premiums between Shanghai and Guangdong showed Guangdong at a 170 yuan/mt premium. The relatively small spread meant there were no inter-regional cargo transfers. According to SMM statistics, as of Thursday, total inventory in Guangdong warehouses stood at 12,400 mt, down by 10,400 mt from last Thursday. Total warrants were 4,500 mt, down by 1,300 mt from last Thursday. Specifically: Warehouse arrivals this week were 8,200 mt/week, down 5,300 mt/week WoW, well below the annual average (14,000 mt/week). Smelter shipments decreased significantly this week, and imported copper volumes were also limited. Warehouse withdrawals were 18,400 mt/week, up 6,200 mt/week WoW, above the annual average (14,200 mt/week). Sharply lower copper prices and reduced arrivals forced end-users to pick up more cargo from warehouses.

Looking ahead to next week, as the delivery date approaches, arrivals next week are expected to increase compared to this week, while end-use consumption is expected to remain stable. Inventory may stop falling, and spot premiums are expected to hover at highs.

Off-Season Continues, Production Enthusiasm at Copper Billet Enterprises Dampened.

[SMM Brass Billet Flash] The traditional off-season of the downstream copper billet industry continued. Orders from end-use industries showed no notable improvement, and only small-volume restocking on demand was maintained. Destocking of finished brass billet products was slow, and finished product inventories at sampled enterprises stood at 5.14 days this week, up slightly WoW. As copper prices continued to climb, raw material costs for brass billet processing enterprises rose; however, product price pass-through lagged, corporate profits were continuously squeezed, and the production enthusiasm of most enterprises was dampened.

High Raw Material Costs Squeeze Profits, Brass Billet Operating Rate Extends Decline

[SMM Brass Billet Flash] During the week of August 7-13, the weekly operating rate of SMM-surveyed brass billet producers was 48.52%, down 0.16 percentage point WoW and down 1.25 percentage points YoY, continuing its downward trend. Off-season market conditions are unlikely to reverse quickly, and the recovery in actual downstream orders still lacks drivers. Meanwhile, copper prices fluctuated at highs, and the tight supply of recycled brass raw materials persisted. High raw material costs will continue to squeeze corporate profits and curb production willingness. SMM expects the weekly operating rate to edge down further to 48.46% next week, down 1.37 percentage points YoY.
