[Supply Disruptions Persist, Imported TCs Continued to Decline]: Weekly data showed that the average weekly TC of SMM Zn50 domestic ore was unchanged at 1,550 yuan/mt in metal content, and the SMM imported zinc concentrate index fell $4.13/dmt MoM to $11.25/dmt...

At the start of this week, US nonfarm payrolls for February unexpectedly declined, and expectations for US Fed interest rate cuts rebounded somewhat, briefly boosting copper prices. Trump then signaled that tensions between the US and Iran might ease, sending oil prices lower and the US dollar weaker, which triggered a phased rebound in copper prices. However, after oil tankers in the Gulf region came under attack and Iran stated that it would continue to close the Strait of Hormuz, tensions in the Middle East escalated again. Rising crude oil prices lifted safe-haven sentiment, and the stronger US dollar index weighed on copper prices. At the same time, US February CPI came in line with expectations, and market bets on interest rate cuts within the year were scaled back markedly, weakening expectations for macro liquidity. In terms of positioning, bulls continued to reduce positions, and capital turned more cautious. Overall, macro uncertainty and repeated shifts in interest rate cut expectations remain intertwined, and copper prices are still likely to fluctuate rangebound in the short term. Fundamentals side, TC in the copper concentrates market was still falling. Recent mine tender prices pointed to a median of -$60/mt. For copper cathode, the inventory buildup showed a turning point, and the import window opened slightly. According to SMM, downstream operating activity was more active than expected, with active pricing below the copper price range of 100,000 yuan/mt. Looking ahead to next week, the macro logic is expected to remain unchanged, and geopolitical tensions are still expected to provide strong support to the US dollar, leaving significant short-term resistance for copper prices. However, fundamentals are supporting copper prices, which are expected to remain fluctuating near the range in the short term. LME copper is expected to fluctuate between $12,800/mt and $13,200/mt, and SHFE copper between 99,000 yuan/mt and 101,000 yuan/mt. In the spot market, as delivery approaches, spot market trading logic will fluctuate with the price spread between futures contracts and funding costs, and is expected to gradually rise next week. Spot prices against the SHFE copper 2604 contract are expected to range from a discount of 180 yuan/mt to a discount of 80 yuan/mt.

On March 13, 2026, China's copper smelting industry set a new historical record. According to SMM data, the imported copper concentrate index closed at -60.39 USD/dmt, officially breaking through the -60 USD level.

[Frequent Supply Disruptions; Imported TCs Continued to Decline]: Weekly data showed that the average weekly TC for SMM Zn50 domestic remained flat at 1,550 yuan/mt in metal content, while the SMM Imported Zinc Concentrate Index fell by $8.37/dmt MoM to $15.38/dmt...

[Zinc Fundamental Trading Logic Amid the Middle East Conflict: Risk Identification and Opportunity Capture] Global geopolitical conflicts have continued unabated, and news of the recent Middle East conflict has emerged frequently. What impact will this have on the zinc industry? This article provides an analysis from both fundamental and market perspectives:

As of February 27, the SMM Zn50 domestic weekly TC average price rose by 50 yuan/mt in metal content from the pre-holiday level to 1,550 yuan/mt in metal content. According to SMM, as the Chinese New Year holiday ended, domestic mines gradually resumed production. Meanwhile, imported zinc concentrates previously ordered by smelters continued to arrive, leaving domestic smelters' raw material inventory relatively ample. Consequently, processing fees in some domestic regions increased for March.

[TCs Rose in Some Regions in March, Focus on Subsequent Negotiation Results]: On a weekly basis, the SMM Zn50 domestic weekly TC average increased by 50 yuan/mt in metal content from the pre-holiday level to 1,550 yuan/mt in metal content, while the SMM imported zinc concentrate index decreased by $0.6/dmt from the pre-holiday level to $23.75/dmt...

Entering March, as the bullish sentiment in precious metal prices weakened, some lead smelters became less willing to obtain silver-bearing lead concentrates raw materials by paying lower TCs. Although lead concentrate TCs have yet to see a substantive rebound, smelters generally stated that it remained difficult for mainstream lead concentrate TC quotations to rise in March, but the phenomenon of transactions involving scrambling for ore at extremely low prices has disappeared. As the absolute level of silver prices can still enable smelters to obtain relatively substantial profits, in March smelters did not have expectations of negotiating downward the relevant payable indicator.

SMM Analysis: In 2025, China's smelting and refining capacity grew, while the TC for copper concentrates continued to deteriorate. Against this backdrop, smelters were compelled to adjust their raw material mix, with copper scrap, blister copper, and anode plates becoming key substitutes and supplements...
