The most significant change in the imported copper concentrate market in the first half of 2026 emerged during the mid-year term-contract negotiations. According to SMM, Antofagasta, a leading Chilean mining company, and several major Chinese smelters finalized the pricing mechanism for their mid-year copper concentrate term contracts on July 1. Rather than continuing with the traditional fixed-TC approach, the parties adopted an index-linked pricing mechanism.Chinese smelters had already agreed with Antofagasta on historically low term-contract treatment and refining charges of US$0 per dry metric tonne and US¢0 per pound in 2025. The further introduction of index-based pricing in the 2026 mid-year negotiations indicates that the pricing framework for imported copper concentrate term contracts is undergoing a structural transformation, against a backdrop of persistently and deeply negative spot TCs and steadily strengthening pricing power on the mine side. At a more fundamental level, the change in term-contract pricing reflects the persistent mismatch between mine-supply growth and the expansion of smelting demand. SMM estimates that global sulfide copper concentrate supply will increase by approximately 250,000 tonnes of contained copper in 2026 compared with 2025, representing growth of around 1.3%. By contrast, newly commissioned and expanded primary smelting capacity in China is expected to generate approximately 800,000 tonnes of additional concentrate demand on a contained-copper basis.The increase in mine supply is therefore significantly smaller than the expansion in smelter demand. Meanwhile, factors including the slower-than-expected restart of Grasberg, the continued absence of a full restart at Cobre Panamá, declining ore grades at mature Chilean mines, and the lingering effects of seismic activity at Kamoa-Kakula kept the imported copper concentrate spot market extremely tight throughout the first half of the year.SMM estimates that the global sulfide copper concentrate market will record a supply deficit of approximately 610,000 tonnes of contained copper in 2026. The shortage may not begin to ease until around 2029, when production from a number of new mine projects is expected to come on stream. At the same time, elevated sulfur and sulfuric acid prices have provided an important floor under copper smelter profitability and increased smelters’ ability to absorb deeply negative TCs, at least temporarily. On July 3, the SMM China Copper Smelter Sulfuric Acid Index stood at RMB 1,789 per tonne, up RMB 886 per tonne from RMB 903 per tonne on January 9. The rise in sulfuric acid prices since the beginning of 2026 has become an important earnings driver for Chinese copper smelters and has helped sustain high refined-copper output. Under the combined influence of the mine-smelter supply-demand mismatch and strong by-product margins, spot TCs for imported copper concentrate continued to fall during the first half of 2026. The monthly SMM Imported Copper Concentrate Index averaged negative US$121.44 per dry metric tonne in June, down US$18.31 per dry metric tonne from negative US$103.13 per dry metric tonne in May. On a weekly basis, the SMM Imported Copper Concentrate Index was reported at negative US$113.83 per dry metric tonne in early June and subsequently declined continuously to negative US$124.45 per dry metric tonne on June 26. On July 3, the weekly index fell further to negative US$128.25 per dry metric tonne, down US$3.80 per dry metric tonne from the previous assessment. The successive declines through the negative US$100 and negative US$120 per dry metric tonne thresholds demonstrate that the shortage of tradable spot concentrate continued to intensify. I. Supply: New Supply Falls Short of Expectations as Mine-Side Disruptions Continue to Constrain Tradable Availability Although several global copper projects were scheduled to deliver incremental concentrate supply in the first half of 2026, actual production growth came on stream significantly more slowly than the market had previously expected.The central issue on the supply side was not any single mine incident. Rather, disruptions at major mines, declining grades at mature operations, slower-than-expected ramp-ups at new projects, and changes in trade flows collectively reduced the volume of concentrate available for purchase in China’s spot market. Regarding Cobre Panamá, the Panamanian government approved First Quantum Minerals in April to remove, process and export stockpiled ore that had been mined before the operation was suspended. According to SMM, however, the current progress at Cobre Panamá mainly concerns the treatment of existing stockpiles and does not represent a full restart of mining operations.The mine remains subject to complex disputes involving mining rights, taxation, environmental requirements, local communities and political considerations. Consequently, even if a portion of the stockpiled material enters the market during the second half of 2026, its contribution to improving the global copper concentrate balance is expected to remain limited.Related analysis is available in the SMM article, “Cobre Panamá Copper Mine: From a World-Class Mine to a Shutdown Impasse—SGS Audit Signals the Possibility of a Restart”: https://hq.smm.cn/copper/content/103965399 Grasberg remains one of the largest variables affecting global copper concentrate supply in 2026. At the beginning of the year, Freeport-McMoRan forecast approximately 3.4 billion pounds of copper sales for 2026, based on the assumption that the Grasberg Block Cave would restart and ramp up in stages from the second quarter.Because the restart underperformed expectations, Freeport subsequently lowered its 2026 copper sales guidance to approximately 3.1 billion pounds in its first-quarter report. For the imported copper concentrate market, the significance of Grasberg extends beyond the mine’s headline production figures. Other important factors include the proportion of concentrate absorbed by Indonesia’s domestic smelting sector, PTFI’s smelter inventory arrangements, and the actual quantity of material available for shipment to China’s spot market. Should the recovery at Grasberg continue to fall short of expectations in the second half of the year, the shortage of clean spot concentrate is unlikely to ease materially. In Africa, the effects of seismic activity at Kamoa-Kakula remain ongoing. Ivanhoe Mines previously issued 2026 copper production guidance of 380,000–420,000 tonnes for Kamoa-Kakula, followed by 500,000–540,000 tonnes in 2027. The company also stated that dewatering and rehabilitation work at the Kakula mine was continuing.Compared with the previous medium- to long-term target of annualized production exceeding 550,000 tonnes, however, the pace of production growth in 2026 has slowed significantly. Kamoa-Kakula had been expected to be one of the most important sources of global copper concentrate supply growth in recent years. The slowdown in its production ramp-up has therefore further reduced the potential for mine-supply growth to support a recovery in TCs. In Chile, declining grades at mature mines, transitions toward deeper underground mining, and operational accidents continued to constrain supply flexibility. The effects of the 2025 cave-in at El Teniente extended into 2026. Codelco previously stated that the accident had resulted in the loss of tens of thousands of tonnes of copper production in 2025 and would continue to affect the subsequent recovery schedule.The incident illustrates the structural challenges facing Chile’s large and mature mining operations in areas such as deep-level mining, ground-pressure management, and the timely delivery of replacement and mine-life-extension projects. In addition to El Teniente, several other major Chilean mines continued to face declining grades, throughput fluctuations and maintenance-related disruptions, limiting the recovery potential of Chilean clean-concentrate supply. Peru’s supply performance was comparatively more resilient than Chile’s, although incremental production remained highly concentrated among a limited number of operations. Major mines such as Antamina and Las Bambas benefited during certain periods from higher ore grades, improved recoveries and operational normalization, supporting Peru’s overall copper production.From the perspective of the imported spot market, however, Peruvian supply remains exposed to community disruptions, transportation-corridor interruptions, mine-grade transitions and unstable shipment schedules. Moreover, because much of the incremental production is concentrated among a small number of large mines, it is insufficient to fully offset supply losses associated with Grasberg, Cobre Panamá and mature Chilean mines. In Mongolia, the ramp-up of the Oyu Tolgoi underground mine represents one of the relatively few clearly identifiable sources of incremental global mine supply in 2026. Rio Tinto disclosed that its copper production increased by 11% year on year in 2025, primarily due to the strong ramp-up at Oyu Tolgoi.Nevertheless, while additional output from Oyu Tolgoi is contributing to global supply growth, the incremental volume from this single project remains insufficient to reverse the overall tightness in the copper concentrate spot market, given the larger increase in Chinese smelting demand and recurring disruptions at other major mines. According to SMM estimates, disruptions at major global copper mines and incremental production falling short of expectations will have a combined impact of approximately 480,000 tonnes of contained copper in 2026. Uncertainty surrounding the realization of mine supply therefore remains the primary factor driving imported copper concentrate TCs lower. From a trade-flow perspective, China’s copper concentrate imports from Chile and Peru both declined to varying degrees during the first half of 2026. According to customs data, China imported 3.7640 million tonnes of copper concentrate from Chile during January–May 2026, down 228,000 tonnes, or 5.71%, year on year.Imports from Peru totaled 3.1002 million tonnes during the same period, representing a year-on-year decrease of 147,900 tonnes, or 4.55%. Lower arrivals from the principal South American origins intensified competition among Chinese smelters for alternative feedstocks, blended concentrates, land-transported concentrates and off-specification materials. China’s total imports of copper ores and concentrates amounted to 12.2758 million tonnes during January–May 2026, down 1.01% year on year. The modest decline partly reflected the relatively high comparison base in the corresponding period of 2025. Other contributing factors included strong consumption of copper anode and blister copper in the first quarter, temporary adjustments to some smelters’ raw-material mix, and changes in the arrival schedule of term-contract cargoes.The decline in headline import volumes should therefore not be interpreted simply as evidence of materially weaker concentrate demand from domestic smelters, nor does it have a direct one-to-one relationship with spot TC movements.For the spot market, the more important variables are the marginal volume available outside term contracts, the share of mainstream clean concentrate in the available supply pool, and smelters’ periodic inventory-replenishment requirements. During the first half of 2026, new smelting capacity, continued demand for off-contract inventory replenishment, and frequent mine disruptions kept the spot market tight even though the decline in apparent import volumes was limited. Spot TCs consequently remained under sustained downward pressure. II. Demand: China’s Smelting Expansion Continues While Production Cuts Remain Fragmented On the demand side, Chinese copper smelters remain the principal source of incremental global copper concentrate consumption. Although deeply negative TCs continued to compress core smelting margins during the first half of 2026, and some smelters temporarily reduced operating rates because of maintenance, feedstock constraints and processing-margin losses, the continued commissioning of new and expanded primary smelting capacity kept concentrate demand relatively inelastic. According to SMM statistics, new and expanded primary smelting capacity in China in 2026 is expected to correspond to approximately 800,000 tonnes of contained copper.Newly commissioned capacity typically requires substantial initial feedstock inventories. Even when spot TCs are deeply negative, new production lines must continue purchasing concentrate to ensure operational stability, complete equipment commissioning and ramp-up, and maintain market share. As a result, the practical effectiveness of production cuts by smelters as a mechanism for restoring TCs has been significantly weakened. The Chinese smelting sector in the first half of 2026 was characterized by the coexistence of maintenance-related disruptions and demand generated by capacity expansion. On the one hand, several smelters scheduled maintenance during the second quarter, temporarily reducing concentrate consumption. On the other hand, ramp-ups at newly commissioned facilities, term-contract obligations, low inventory safety margins and strong sulfuric acid earnings prevented smelters from implementing coordinated production cuts.Particularly in an environment where imported concentrate inventories remained structurally tight, some smelters continued to make essential market inquiries to secure production continuity, even when they reduced the frequency of their spot purchases. III. Smelting Economics: Strong Sulfuric Acid Margins Increase Tolerance for Negative TCs, but Volatility Risks Are Rising The earnings structure of copper smelters changed materially during the first half of 2026. Traditionally, smelter profitability has primarily been derived from TC/RC income and credits from gold, silver and other by-products. With spot TCs for imported copper concentrate moving deeply into negative territory, however, processing-fee income fell sharply and sulfuric acid margins became significantly more important. Overall copper smelting margins were weaker in the early part of the first half and improved later in the period. Declining TCs imposed substantial pressure on profitability, but elevated sulfuric acid prices, strong precious-metal prices and improved returns from certain other by-products provided a partial offset.Approximately 3.5–4.0 tonnes of sulfuric acid are produced as a by-product for every tonne of refined copper output. When sulfuric acid prices are high, acid earnings can substantially offset the impact of negative TCs and rising smelting costs. Nevertheless, according to SMM estimates, spot-based smelting margins at Chinese copper smelters have now approached break-even, and smelters have become noticeably less willing to purchase spot cargoes at increasingly unfavorable TCs. The rise in sulfuric acid prices has mainly been driven by two factors. First, geopolitical disruptions in the Middle East, tight sulfur supply and higher import costs raised the cost base of sulfuric acid production. Second, demand from phosphate fertilizers, chemicals, hydrometallurgical operations and battery-material producers provided broad-based downstream support.The sharp rise in sulfuric acid prices has reshaped the economics of copper smelting in China, with acid earnings accounting for a substantially larger proportion of smelters’ non-TC/RC income. This was also an important reason why Chinese smelters did not implement large-scale voluntary production cuts during the first half of 2026 despite the continued decline in TCs. The support provided by sulfuric acid margins is not without risk, however. Should geopolitical disruptions ease in the second half of the year, sulfur supply recover, or restrictions on Chinese sulfuric acid exports result in more material being redirected to the domestic market, sulfuric acid prices could retreat from their elevated levels.If acid margins narrow while copper concentrate TCs remain deeply negative, pressure on smelter profitability will become more visible again. Some higher-cost smelters may respond by extending maintenance periods, reducing utilization rates or cutting spot concentrate purchases. Sulfuric acid prices will therefore be one of the key variables determining whether TCs can stabilize during the second half of the year. IV. Spot Market: Frequent Mine Tenders and the Emergence of Index-Minus Pricing Trading activity in the imported copper concentrate spot market was uneven during the first half of 2026, but mine tenders and trader offers remained important channels for price discovery. As spot TCs continued to decline, outright fixed-price transactions repeatedly established new market lows, while index-minus pricing gradually became the dominant quotation format. Since the second quarter, trader offers have increasingly been expressed as an average of the SMM and Fastmarkets indices minus an additional differential. This pricing method indicates that, in an environment of continuously declining spot TCs, concentrate sellers increasingly prefer index-linked formulas that preserve their exposure to further downward movements in TCs. Smelters’ purchasing behavior remained conflicted. On the one hand, deeply negative TCs continued to compress smelting margins, limiting smelters’ willingness to accept expensive spot concentrate carrying extremely unfavorable processing terms. Some companies therefore reduced the frequency of their active inquiries.On the other hand, ramp-ups at new smelting facilities, insufficient inventory safety margins and uncertainty surrounding term-contract arrivals meant that some smelters still needed to replenish stocks to meet essential production requirements. Consequently, the market did not experience a collective withdrawal of buyers sufficient to drive a meaningful recovery in TCs. Instead, continuously lower mine-tender settlements pushed the spot index further into deeply negative territory. V. H2 Outlook: Limited Marginal Supply Recovery and Persistently Deeply Negative TCs Looking ahead to the second half of 2026, the imported copper concentrate spot market will continue to be driven by the interaction between the actual realization of mine-supply recovery and the resilience of Chinese smelting demand.On the supply side, the treatment of Cobre Panamá stockpiles, progress in the Grasberg restart, incremental production from Oyu Tolgoi, and shipment stability at major Peruvian mines may provide some marginal improvement. Based on current developments, however, Cobre Panamá has not achieved a full restart, the Grasberg recovery schedule has already been revised downward, production growth at Kamoa-Kakula has slowed, and mature Chilean mines remain exposed to declining grades and safety-related disruptions. The conditions required for a substantial easing of the global copper concentrate market are therefore not yet in place. On the demand side, new and expanded Chinese primary smelting capacity will continue to support structurally strong concentrate consumption. Although some smelters may temporarily reduce production because of losses, maintenance or feedstock constraints, the ramp-up of newly commissioned projects, the fulfillment of term contracts, sulfuric acid margins and regional refined-copper price differentials will continue to weaken the impact of production cuts on TCs.Should the effect of maintenance outages gradually diminish during the third quarter while newly commissioned capacity continues to ramp up, China’s demand for imported copper concentrate is likely to remain elevated on a sequential basis. Sulfuric acid prices will remain a key variable for smelting profitability in the second half of the year. Should sulfuric acid prices remain elevated or rise further, smelters will continue to demonstrate a relatively strong capacity to absorb negative TCs, limiting the potential for a recovery in spot TCs. Conversely, should sulfuric acid prices retreat from their highs, pressure on smelter profitability will increase again. Some smelters may respond by extending maintenance, cutting operating rates or reducing spot purchases, potentially allowing TCs to stabilize or recover modestly for a period. In the spot market, mine-tender results will remain an important leading indicator for TC movements in the second half of the year. As term-contract pricing becomes increasingly index-linked and more spot transactions adopt index-minus formulas, the SMM Imported Copper Concentrate Index is expected to play an even stronger role as the principal pricing anchor for market transactions. Should mine-tender settlements remain deeply negative, spot TCs may fall further. Conversely, if incremental volumes from the Grasberg recovery, Cobre Panamá stockpile processing and Oyu Tolgoi materialize at the same time, while maintenance activity among smelters increases, TCs may stage a temporary recovery. Overall, some marginal improvement in imported copper concentrate supply is possible during the second half of 2026. Nevertheless, given the continued commissioning of new Chinese smelting capacity, the shortage of tradable concentrate, and the support that strong sulfuric acid margins provide to smelter operating rates, a sustained and substantial recovery in spot TCs appears unlikely. Spot TCs for imported copper concentrate are therefore expected to remain volatile within deeply negative territory during the second half of the year. Any temporary recovery will depend largely on the actual realization of mine restarts, the extent to which smelters implement maintenance and production cuts, and changes in sulfuric acid profitability.

A strike has commenced at JFR Moquegua in Peru, may cause immediate shipment delays for Anglo American’s Quellaveco and Grupo México. There is a growing risk that the strike action could escalate and spread to the Arequipa region, potentially disrupting operations at Matarani Port. If this occurs, shipments for other major mines—including Las Bambas, Cerro Verde, and Constancia—will face subsequent delays.

According to SMM, the JFR union in Peru's Moquegua region has started a strike, which is expected to delay shipments from the Quellaveco mine and Grupo México's mines. Moreover, the strike may spread to the Matarani port in Arequipa; if it affects this port, it will further impact the shipment pace of other major mines such as Las Bambas, Cerro Verde, and Constancia. It remains to be confirmed whether the strike will extend to Arequipa, and further developments will be reported separately.

South America remains the cornerstone of global copper supply, with Chile and Peru collectively accounting for more than one-third of global mined copper production. As electrification, grid modernisation, renewable energy deployment and AI-driven infrastructure investment continue to reinforce long-term copper demand growth, policy developments across the region are becoming increasingly important determinants of future supply availability.

The International Copper Study Group (ICSG) released preliminary data on global copper supply and demand for March 2026 in its monthly bulletin published in May 2026. Preliminary data indicated that global copper mine production in Q1 2026 was basically flat, with copper concentrates production declining by 1.1%, offset by a 3.3% increase in solvent extraction-electrodeposition (SX-EW) production. Although global mine production benefited from additional output driven by capacity ramp-up of projects in several countries, significant declines in copper concentrates production in Chile, the DRC, and Indonesia offset global growth. In Indonesia, copper concentrates production at the Grasberg mine fell by 42%, as the severe mud inflow incident that occurred in September last year continued to affect the mine's production. Chile's mine production declined by 5.8%, with increased production at the Collahuasi and Quebrada Blanca mines offset by production cuts at the Spence, El Teniente, Escondida, and Los Pelambres mines. The DRC's mine production is estimated to have grown by only 0.5%: SX-EW production increased by approximately 10%, but was partially offset by a 36% decline in copper concentrates production due to reduced output at the Kamoa mine (affected by the 2025 earthquake event). In Peru, copper mine production grew by 3.3%, primarily driven by increased production at the Antamina, Las Bambas, and Antapaccay mines, which more than offset production declines at Southern Peru Copper, Quellaveco, and Marcobre. Mongolia's copper concentrates production is estimated to have grown by approximately 36%, benefiting from the capacity ramp-up of the Oyu Tolgoi underground project. Preliminary data indicated that global copper cathode production grew by approximately 4.5% in Q1 2026, with primary copper (electrolysis and ore electrodeposition) production increasing by 3.8% and secondary copper (from scrap) production increasing by 7.6%. China and the DRC, which currently account for approximately 60% of global production, saw their combined production increase by an estimated 9% (China 8.8%, DRC 10%). Excluding these two countries, global copper cathode production declined by approximately 1.4%. Chile's copper cathode production fell by 11.7%, with copper cathode (from concentrates) production declining by 24% due to smelter operational constraints and maintenance, and electrodeposition copper production declining by 5.7%. Production in Asia (excluding China) is estimated to have declined by 4%, mainly due to production decreases in Japan, Indonesia, and the Philippines. India's production is estimated to have grown by 25%, benefiting from improved capacity utilization rates and the capacity ramp-up of the Adani smelter. Global secondary refined copper production (from scrap) increased by 7.6%, mainly driven by growth in China. Preliminary data indicated that global apparent refined copper usage grew by 0.8% in Q1 2026. Although global usage excluding China was estimated to have grown by 1.7%, China's apparent demand (excluding bonded warehouse/unreported inventory changes) was estimated to be basically flat, affected by a 40% decline in China's net imports of copper cathode. China currently accounts for approximately 58% of total global refined copper usage. The preliminary global refined copper supply-demand balance indicated an oversupply of 396,000 mt in Q1 2026. In compiling the global market balance, ICSG used China's apparent demand calculation method, which does not account for changes in unreported inventories. However, to facilitate global market analysis, an adjustment item has been added to the attached tables — "Global refined copper balance adjusted for Chinese bonded warehouse inventory changes" — which adjusts the global refined copper balance based on the average bonded warehouse inventory change estimates from two Chinese copper market consultancies. In Q1 2026, the global refined copper balance based on China's apparent usage (excluding bonded warehouse/unreported inventory changes) showed a preliminary oversupply of approximately 396,000 mt, compared with an oversupply of approximately 135,000 mt in the same period of 2025. The global refined copper balance adjusted for estimated changes in Chinese bonded warehouse inventories showed a market oversupply of approximately 386,000 mt. Copper Prices and Inventories: Based on the average estimates from two independent consultancies, Chinese bonded warehouse inventories were estimated to have decreased by approximately 10,000 mt from the end of 2025 levels during the first three months of 2026. As of the end of April 2026, copper inventories at major metal exchanges (LME, COMEX, SHFE) totaled 1,148,760 mt, the highest level since January 2003. Inventories increased by 404,648 mt, or 55%, from the end of December 2025, with LME up 253,350 mt, Shanghai Futures Exchange up 46,683 mt, and COMEX up 104,615 mt. The LME spot copper average price in April was $12,891.38 per mt, up 3% from the March average price of $12,498.98 per mt. The 2026 copper price high and low were $14,097 per mt (May 13) and $11,826 per mt (March 19), respectively, with a year-to-date average price of $12,947.22 per mt, up 30% from the 2025 average price.

On April 24, the SMM Imported Copper Concentrate Index (weekly) stood at -81.44 USD/dmt, down 2.83 USD/dmt from the previous reading of -78.61 USD/dmt. The deeply negative TC reflects the tightness in the global copper concentrate market, which has already shifted from market expectations to an actual rigid contraction in supply. In the first quarter of 2026, the world's leading mining companies frequently revised down their production guidance, with supply-side disruptions far exceeding early-year forecasts. Freeport significantly lowered its full-year 2026 copper production forecast from 1.542 million tonnes to approximately 1.406 million tonnes, with an expected recovery rate of only 65%, due to slower-than-expected mine recovery at its Grasberg site in Indonesia, affected by mudslides and ore moisture. In addition, road blockades caused by strikes at BHP's Escondida and Zaldivar mines have led to actual production impacts that remain to be monitored. According to SMM exclusive data, the global copper concentrate deficit in 2026 is estimated at 317,000 metal tonnes, a situation that may ease somewhat in 2029. In stark contrast to the persistently falling TC, domestic smelter operating rates remained high in Q1 2026. According to SMM data, China's electrolytic copper output in March 2026 reached 1.2061 million tonnes, up 5.58% month-on-month and 7.49% year-on-year. In Q1 2026, total electrolytic copper output was 3.5278 million tonnes, up 4.60% quarter-on-quarter and 10.45% year-on-year. SMM survey data shows that 11 smelters have confirmed maintenance schedules for Q2 2026. This means that domestic electrolytic copper output is expected to decline in Q2, with spot supplies likely tightening temporarily in May and June. However, some smelters have reported that due to high sulfuric acid prices, maintenance completion times may be brought forward. Sulfuric acid is currently the most important by-product revenue source for the copper smelting industry. According to SMM data, on April 24, 2026, China's copper smelting acid index stood at 1,660.5 RMB/ton, up 31.5 RMB/ton from the previous period. As sulfuric acid revenues have risen steadily from 890 RMB/ton at the start of 2026 to 1,660.5 RMB/ton in April 2026, based on the co-production of 3–4.5 tonnes of sulfuric acid per tonne of electrolytic copper, sulfuric acid income can now cover the copper concentrate procurement cost and part of the processing cost for smelters. The upward slope and magnitude of this increase exceed the deterioration in spot TC. The substantial boost in sulfuric acid profitability allows smelters to tolerate lower TC, creating a cycle of "higher sulfuric acid prices, lower TC." Meanwhile, rising gold and silver prices have further expanded smelters' comprehensive profit margins. Although the copper smelting segment is deeply loss-making, driven by the hefty profits from sulfuric acid, gold, and silver, domestic copper smelters have been able to maintain high operating rates without large-scale production cuts caused by deeply negative TC. Additionally, about 20% of the world's electrolytic copper comes from hydrometallurgical processes, with the DRC and Chile together accounting for nearly 80% of that. Hydrometallurgical copper production consumes large amounts of sulfuric acid, and sulfur is a key raw material for sulfuric acid. The current disruption in the Strait of Hormuz has cut off approximately 50–60% of Middle Eastern sulfur shipments by sea, pushing up sulfur and sulfuric acid prices. Worth noting is that as late April 2026 progresses, sulfuric acid export restrictions combined with increased domestic production have shown signs of price softening. If sulfuric acid prices continue to decline, it will directly squeeze the comprehensive profit margins of domestic smelters. At that point, the dual pressure of persistently low TC and falling sulfuric acid prices could trigger real production cuts on the smelting side. Although gold and silver prices do not directly determine TC trends, their macro-pricing logic as part of the non-ferrous metals sector is worth attention. The market has largely priced in the expectation that the Federal Reserve will not cut interest rates at all in 2026, with the first rate cut possibly delayed until July 2027. For copper, a delayed rate cut means no near-term easing of macro liquidity, but copper's core pricing logic remains the ongoing tug-of-war between tightening supply on the mining side and rigid demand. In other words, precious metals are under pressure, but industrial metals' pricing center remains in real supply-demand fundamentals, which explains why weaker gold and silver prices have not dragged copper prices lower. According to SMM, for Chinese smelters, domestic copper concentrate spot TC transactions are feasible in the range of -81 USD/dmt to -88 USD/dmt. Some holders have attempted to offer TC at -100 USD/dmt, while some smelters are willing to accept deliveries at the lower end around -90 USD/dmt. The downward trend in TC has not yet stopped, and smelter purchasing activity may have weakened slightly, but not significantly. Key areas to watch moving forward: Sulfuric acid side: The price trend will depend on the interplay of multiple factors. First, China's sulfuric acid export policy direction: if export restrictions continue, domestic sulfuric acid supply will be relatively abundant, and prices may fall from highs; if exports are temporarily allowed, overseas hydrometallurgical copper supply risks will rise, but domestic sulfuric acid prices may find support. Second, the recovery of sulfur supply: when shipping through the Strait of Hormuz returns to normal will directly affect the pace at which Middle Eastern sulfur can supplement global markets. Third, seasonal demand changes for downstream products such as phosphate fertilizers will also cause periodic price volatility for sulfuric acid. Mining side: Focus on the progress of the Grasberg conversion project, labor negotiation results at Chilean mines, and logistics stability at mines such as Las Bambas in Peru. Any new supply release will effectively ease TC pressure. Macro side: Monitor the Federal Reserve's monetary policy path, the U.S. dollar index, the actual driving effect of China's pro-growth policies on copper consumption, and whether the growth rate of copper demand in global new energy sectors is slowing marginally.

MMG Limited (MMG) has made a strong start to 2026, delivering solid first quarter production results and safety improvements.Total copper production, including copper in concentrate and cathode, increased nine per cent year-on-year to 128,698 tonnes. A result underpinned by robust performances at Las Bambas and Kinsevere. Precious metals production was also impressive, with gold output increasing by 24 per cent and silver by 27 per cent compared with the prior year period. Group precious metals production totalled 32,177 ounces of gold and 2,888,861 ounces of silver. Total zinc production was 50,263 tonnes, three per cent lower than the prior year.

[SMM Analysis: Reshaping Cu Cons Trade Flows: China's New Raw Material Strategy Landscape Amid Geopolitical Chessboard] According to data from the General Administration of Customs, China imported 2.704 million dmt of copper ore and concentrates in December 2025, a month-on-month increase of 7% and a year-on-year increase of 7.2%. From January to December, China’s cumulative imports of copper ore and concentrates reached 30.365 million dmt, a cumulative year-on-year increase of 7.8%.
