[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:

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.

[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...

SMM Morning Meeting Minutes: Overnight, LME copper opened at $12,960/mt. It fluctuated downward in early trading, dipping to $12,792/mt, after which the center of copper prices gradually moved higher and touched a high of $12,966/mt. It then fluctuated downward and finally closed at $12,859/mt, down 1.29%. Trading volume rose to 27,900 lots, and open interest rose to 305,000 lots, down 953 lots from the previous trading day, mainly due to long position reductions. Overnight, the most-traded SHFE copper 2604 contract opened at 100,440 yuan/mt. It fluctuated downward in early trading and bottomed at 100,030 yuan/mt, after which the center of copper prices moved sharply higher and climbed to 101,410 yuan/mt. It finally closed at 100,980 yuan/mt, down 0.35%. Trading volume rose to 74,300 lots, and open interest rose to 195,000 lots, down 5,732 lots from the previous trading day, mainly due to long position reductions.

On June 12th, Bloomberg reported that Teck Resources and Sumitomo Metal Mining are locked in a dispute over treatment and refining charges (TC/RCs) in a major copper concentrate supply agreement. The disagreement, centered on shipments from Teck’s Quebrada Blanca and Highland Valley mines, has prompted the appointment of lawyers to select an industry expert as an independent referee. The clash highlights cracks in the traditional benchmark pricing system, after Antofagasta’s 2025 deal with Chinese smelters set TC/RCs at $21.25/2.125 cents, far below historical norms. Some Japanese buyers, including Sumitomo, have resisted adopting this benchmark amid sharply falling spot TC/RCs, which have recently turned negative. The situation underscores growing tension between well-funded Chinese smelters and financially pressured Western peers, with some smelters in the Philippines and Namibia already suspending operations.

The CSPT Working Group convened its first quarter general manager's office meeting in Shanghai on March 28, 2024. After discussion, the meeting reached the following five consensuses:

Yunnan Copper said that its copper concentrate TC/RC under long-term contracts in 2023 are higher than in 2022

SMM reported that the CSPT team held a general manager's office meeting for the first quarter of 2025 in Shanghai on the morning of March 31, and decide not to set a second quarter copper concentrate spot purchase guidance TC/RC.

According to SMM, both supply and demand in the lead concentrate market declined in February. Smelters in Hunan and Yunnan suspended raw material procurement offers due to maintenance shutdowns during the Chinese New Year holiday. Some producers adopted a cautious purchasing approach towards silver in silver-bearing lead ores, fearing a price decline. The short-term unilateral bullish sentiment for silver has significantly faded. The payable indicator for silver contained in lead concentrates remained stable in the near term. Should silver prices enter a downward trend, smelters may consider negotiating a lower coefficient. Although extreme offers, where smelters actively reduce TCs to "snap up" silver-bearing lead concentrate raw materials, have almost disappeared after the holiday, a few small-scale, low-silver lead mines slightly increased lead concentrate TCs to hedge against silver price downside risks. However, smelters generally indicated that it remains difficult to raise mainstream lead concentrate TC offers in March.

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...
