【Zinc Concentrate Tender】According to SMM, a zinc mine in Southwest China recently concluded its July zinc concentrate tender, with the mine pickup tender price settling at around -RMB 800 per metal tonne, down approximately RMB 700 per metal tonne from the previous month. SMM will continue to monitor subsequent changes in zinc concentrate treatment charges (TCs).

Russian base metal producer Norilsk Nickel expects the global copper concentrate market to remain in undersupply in 2026, with a deficit of 751,000 mt, which will continue to put pressure on processing enterprises' profits.The company stated in its copper market outlook report released on June 23 that benchmark treatment charges (TCs) for copper concentrates under the 2026 annual contract framework have been set at $0/mt, down from $21/mt in 2025, as smelting capacity continues to compete for scarce concentrate supply.

According to the latest customs data, China imported 396,500 metric tons (gross weight) of zinc concentrate in May 2026, down 11.42% (51,100 metric tons) from April and 19.31% lower year-on-year. Cumulative imports during January–May reached 2.3987 million metric tons, representing an increase of 8.84% compared with the same period last year.

Time flies as the midpoint of 2026 approaches. The zinc concentrate market has witnessed another extraordinary price cycle this year. As of June 12, domestic zinc concentrate treatment charges (TCs) plunged to -50 yuan per metric ton of zinc metal, marking the arrival of negative TCs. Meanwhile, TCs for imported zinc concentrate tumbled to -71.2 US dollars per dry metric ton, both hitting all-time record lows.

Central Asia Metals (CAML) announced that, thanks to improved operational efficiencies, its copper and zinc production for the first five months of 2026 both surpassed the same period last year. Copper output from the Kounrad operation in Kazakhstan totalled 5,141 tonnes, a near 4% increase over the last year. Meanwhile, the Sasa mine in North Macedonia produced 7,566 tonnes of zinc in concentrate, up over 2% compared to last year. In terms of pricing, the company reported significantly higher realized metal prices during the period. The average price of copper reached $13,076 per tonnes, representing a massive jump of nearly 40% over the last year, while average zinc prices rose 19% to $3,299 per tonne. In addition, historically low treatment charges for lead, which have turned negative, further boosted Sasa’s revenues. CEO Gavin Ferrar noted that the group is shaping up to deliver strong profitability and cash generation in the first half of 2026. Currently, the company is actively pushing forward with its acquisition of Australia's Cygnus Metals, announced last week, to expand its footprint into a high-grade copper-gold project in Quebec, Canada. The company remains highly confident in meeting its full-year production guidance (12,000–13,000 tonnes of copper, 18,000–20,000 tonnes of zinc concentrates, and 26,000–28,000 tonnes of lead concentrates).

【Domestic Zinc Concentrate Market】Domestic smelters maintained steady purchasing volumes of domestic zinc concentrate this week, and the tight supply pattern of domestic zinc concentrate persisted. Treatment charges kept edging down across most regions. Except for individual northern provinces, treatment charges for domestic zinc concentrate have generally slipped into negative territory nationwide.

【Domestic Zinc Concentrate Tender】According to SMM, a mine in northwest China recently launched a self-pickup tender for June zinc concentrate at a treatment charge below -700 RMB per metal ton, representing a month-on-month drop of approximately 1,000 RMB per metal ton. SMM will keep tracking subsequent fluctuations in treatment charges.

As we near the midpoint of the year, zinc concentrate treatment charges (TCs) have repeatedly tumbled to historic lows. As of June 5, the average TC for domestic zinc concentrate fell to 50 yuan per metric ton of metal content, while the TC for imported zinc concentrate dropped to -70.75 US dollars per dry metric ton.

According to the China Earthquake Networks Center, at 5:52 AM Beijing time on May 26, 2026 (5:52 PM local time on May 25), a magnitude 6.9 earthquake struck the Antofagasta Region in northern Chile, with a focal depth of approximately 114 kilometers. The U.S. Geological Survey (USGS) measured the focal depth at approximately 109 kilometers. Within a 200-kilometer radius of the epicenter, 21 earthquakes of magnitude 3 or above have occurred in the past five years, the largest being a magnitude 7.3 earthquake on July 19, 2024. The Antofagasta Region is Chile's core mining area and a globally significant copper mine concentration zone. Following the earthquake, the global copper market quickly turned its attention to local mine production and transportation conditions. Codelco stated that due to low visibility in mine pits and localized power outages, the company had suspended some production activities and initiated safety inspection procedures. According to SMM, the affected mines under Codelco have now resumed normal production. Global mining giant BHP and Antofagasta PLC indicated that their operations were generally unaffected, but they had temporarily halted some operations in accordance with emergency protocols to conduct safety assessments of facilities. Chile's National Disaster Prevention and Response Service (SENAPRED) reported that the earthquake triggered landslides in some production areas, and Calama experienced power outages and localized water supply disruptions. However, no casualties or major infrastructure damage had been reported, and ports and major transportation facilities were currently operating normally. Although this earthquake was of relatively high magnitude with a deep focal point, given Chile's relatively mature seismic-resistant mining infrastructure system, the actual impact of this event on the global copper supply chain was temporarily limited, manifesting more as short-term sentiment disturbance. However, as the world's largest copper-producing country, Chile holds a pivotal position in the global copper supply chain. Data from China's General Administration of Customs showed that from January to April 2026, China imported a total of 9.9151 million mt in physical content of copper concentrates, of which 3.0526 million mt in physical content were imported from Chile, accounting for approximately 30.79%. Chile remained China's largest source of copper concentrates imports. Against the backdrop of already tight global copper concentrates supply and persistently low treatment charges (TCs), any production disruption from Chile's core mining areas could trigger copper price fluctuations. If subsequent situations arise such as prolonged mine shutdowns, hindered port transportation, or slow power restoration, this could further push up international copper prices and the performance of related non-ferrous metals sectors. As of now, major miners in Chile have not disclosed any significant facility damage or long-term shutdown information.

This insight follows panel discussions at SMM’s London H1 2026 seminar, where one theme stood out clearly: funds are trumping fundamentals in today’s copper market. At first glance, the setup looks contradictory. There is no clear physical shortage of copper: near-term time spreads are in contango, signalling adequate supply; SMM forecasts a small global refined surplus in 2026; global exchange stocks are rising. On traditional metrics, prices should be softer. Yet LME copper remains elevated at around $13,000/t. This leads us to believe that copper is no longer trading purely on market fundamentals. So What Is Driving Copper Higher? Financial flows dominate price formation Speculative inflows since the middle of last year have played a key role in pushing copper higher. The recent rally following the initial shock of the US-Iran war is no exception. While some capital has rotated into energy markets recently, inflows into copper and broader commodities have remained resilient, supported by macro funds and systematic positioning. Momentum-driven strategies (CTAs, macro funds) have reinforced upside moves, especially during periods of positive price signals and cross-asset risk appetite. This can be seen from the bottom right hand-side chart which shows speculative positions from the LME’s Commitment of Traders Report (COTR). There has also been selective physical support, particularly from China, where downstream buying and restocking have contributed to declining local inventories at times. However, this physical demand has been opportunistic rather than structural, and insufficient on its own to explain the persistence of elevated prices. Overall, barring the initial geopolitical shock, copper price strength has been largely investor-led rather than consumer-led, with financial capital remaining the dominant marginal driver of price formation. A persistent geopolitical premium Supply risks remain elevated across key producing regions; energy and input cost volatility (e.g. sulphuric acid and diesel) adds uncertainty to production; trade fragmentation and resource nationalism are reshaping supply chains; copper is increasingly priced as a strategic resource, not just a commodity. Policy distortions — particularly from the US Tariff expectations and US government policy aimed at securing domestic supply chains — including potential import tariffs on copper, incentives for local processing, and broader reshoring of manufacturing — have triggered regional stockpiling. This has tightened availability ex-US and distorted global trade flows, as material is increasingly drawn into the US market. In effect, policy is creating artificial tightness in specific regions, even as the global market remains broadly balanced. Structural narrative outweighs current balance Electrification, grid expansion, and AI infrastructure continue to anchor long-term demand; supply constraints (declining ore grades, permitting delays) remain unresolved. As such, the market is pricing future deficits today, not current surplus. Why Surplus Does Not Equal Lower Prices The key misunderstanding in today’s market is treating copper like a static balance sheet. The surplus is marginal and unevenly distributed. Inventories are not necessarily located where demand is strongest. The market reacts to marginal tightness and risk, not annual average. Most importantly, copper is a forward-looking asset — it prices sentiment and expectations, not just spot fundamentals. How Traders Think About Copper Now Copper price formation has evolved into a multi‑layered system according to our panellists: Price = Fundamentals + Financial Flows + Macro + Narrative By this, we mean that copper prices are driven by four interacting components — Fundamentals, Financial Flows, Macro, and Narrative — and traders now analyse each layer in more depth to anticipate price direction. They: Watch financial conditions — positioning, flows, momentum, correlations Traders look at who holds risk, how strong the flows are, and whether momentum is building or fading. Cross‑asset signals — especially from US equities and major commodity indices — show whether copper is trading as part of a broader risk‑on move or reacting to something more specific. Track macro drivers — interest rates, policy, USD, liquidity Copper reacts quickly to shifts in US real yields, Fed expectations, and the strength of the dollar. Easier financial conditions or a weaker USD can lift prices even when demand is soft. Global liquidity trends, including China’s credit cycle, influence how much speculative capital enters the market. Monitor policy and geopolitics — tariffs, sanctions, trade flows, disruptions Policy decisions now move copper as much as fundamentals. Tariffs, sanctions, and export controls reshape trade flows and create regional imbalances. Geopolitical tensions and supply disruptions — from strikes to permitting delays — reinforce the market’s focus on future scarcity. Stay grounded in physical stress points — inventories, premiums, scrap Headline stocks matter less than where the metal sits. Traders watch regional inventory tightness, premiums, treatment charges, and scrap availability to understand real physical stress. These signals reveal whether the market is genuinely tight or simply trading a narrative. The consensus is that as long as capital flows remain strong, geopolitical risks persist, and the market prices future scarcity, copper can stay elevated — even in surplus. Where Next for Copper? As for immediate near-term dynamics, the copper market is treading water, increasingly driven by headline risk. Recent price action has been closely tied to developments around the Iran crisis, highlighting just how far copper has shifted into the macro arena. The closure of the Strait of Hormuz presents a two-sided risk for copper: On the bullish side , the Gulf is a major exporter of sulphur, a critical input for sulphuric acid used in leaching processes. With solvent extraction and electrowinning accounting for roughly a quarter of global refined output, continued disruptions to acid supply could tighten production, particularly in the DRC, and support prices. On the bearish side , higher energy prices risk triggering a broader slowdown in global manufacturing, weakening copper demand. The longer the disruptions persist, the greater the downside risk to consumption. With investors firmly in control of price formation, copper has effectively become part of a multi-asset macro trade on the trajectory of the Iran conflict. In this environment, both bulls and bears are less anchored to supply-demand balances and more dependent on the next geopolitical headline.
