Against the backdrop of global sustainable development, the recycled metal industry is gaining importance. As the conflict between resource shortages and growing demand intensifies, countries are increasing policy and technology investment in this sector to promote a green economy. Japan, as a key recycled resource hub in Asia, possesses advanced technologies (such as aluminum dross processing) and closed-loop recycling models, and plans to expand the scale of e-waste recycling. However, its domestic capacity to absorb secondary aluminum is limited, necessitating expansion into markets outside China; secondary copper capacity is also expanding simultaneously. Sino-US trade issues have also highlighted the necessity of supply chain stability. Against this backdrop, with the theme "Voice of Low Carbon, Global Resonance," the will be held in Tokyo, Japan, on May 11–12, 2026. At this conference, will participate as an attending company, with Chairman Javier Riba Mas and Asia Manager Jose Maria Lozoya Fontanals in attendance. Global sustainability highlights the importance of the recycled metal sector. With resource shortages intensifying, countries (notably Japan, Asia's recycling hub) are advancing tech and policies. Japan aims to expand e-waste recycling but needs markets outside China for secondary aluminum; secondary copper output is also growing. Sino-US trade tensions further emphasize supply chain stability. 2026 SMM (3rd) Global Renewable Metal Industry Chain Summit (Theme: Voice of Low Carbon, Global Resonance ) is scheduled for May 11–12, 2026 , in Tokyo, Japan . At this conference, RIBA FARRE will attend, with Chairman Javier Riba Mas and Asia Manager Jose Maria Lozoya Fontanals in attendance.

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.

Recently, disruptions caused by the shutdown of the Strait of Hormuz have significantly pushed up logistics and raw material costs across the copper smelting supply chain in the Democratic Republic of the Congo (DRC). Based on on-the-ground field visits, SMM has compiled a summary of the current operating conditions of copper producers in the DRC.

Freeport-McMoRan lowered its 2026 copper output forecast due to slower recovery at its Grasberg mine, now expecting only 65% recovery, significantly reducing global supply expectations.

BHP reported a 7% drop in quarterly copper output but expects full-year production to remain strong, indicating resilience despite operational challenges.

Two of Zambia’s major copper smelters and sulfuric acid producers plan to conduct extended maintenance shutdowns later this year. This will further tighten the country’s copper output and also affect supplies of chemicals such as sulfuric acid used in copper and cobalt processing. Zambia’s copper smelters produce approximately 2 million metric tons of sulfuric acid annually, mostly as a by-product for local mines, with surplus volumes exported to the Democratic Republic of the Congo. Meanwhile, ongoing conflicts in the Middle East have disrupted global supplies of sulfuric acid and other leaching chemicals. As a result, mines in the DRC — the world’s top cobalt producer and second-largest copper producer — have had to reduce chemical usage or even consider cutting production.

The Democratic Republic of Congo has raised planned copper sales to the United States to 500,000 tonnes through a state-backed marketing venture, marking a fivefold increase from its initial January commitment. The deal, first reported by Semafor, is led by state miner Gécamines and marketed through a joint venture with Mercuria Energy Group, with backing from the US International Development Finance Corporation. It targets copper output from Gécamines’ minority stakes in major operations, including Kamoto Copper Company and Tenke Fungurume.

Recently, the center of copper prices continued to shift upward. The most-traded SHFE copper contract steadily climbed after hitting a periodic low of 91,500 yuan/mt on March 23, 2026, reaching a high of 103,130 yuan/mt as of April 15, representing a gain of 12.71% from low to high, with the latest closing price at 102,090 yuan/mt. The latest LME copper price stood at $13,262.5/mt. The interaction between macro sentiment and fundamentals jointly drove the market to hold up well. This round of copper price strength was not dominated by a single factor, but rather the result of a resonance of multiple factors including geopolitical conflicts, supply constraints, inventory changes, and seasonal consumption patterns. Regarding the core driving logic behind the current copper price strength, SMM will provide a detailed analysis from three dimensions: the contraction of SX-EW copper supply outside China, the macro perspective on the US dollar and geopolitical developments, and China's copper inventories and supply-demand pattern. The details are as follows: （I) Sulphuric Acid Export Restriction Policies Strengthened Expectations for SX-EW Copper Production Cuts, and Supply Contraction Supported Copper Prices Sulphuric acid prices have been rising continuously since March, mainly due to the ongoing escalation of tensions in the Middle East. Shipping through the Strait of Hormuz, which carries approximately 50% of the world's seaborne sulphur volume, has been disrupted, leading to an overall tightening of global sulphur supply. In China's sulphuric acid production, approximately 40% comes from sulphur-based acid production and 40% from smelting acid. China is highly dependent on sulphur imports, and the tightness in raw material supply has provided certain support for domestic sulphuric acid prices. The DRC is the world's second-largest copper-producing country, with production highly dependent on sulphuric acid. According to SMM, producing 1 mt of copper cathode locally requires 2–6 mt of sulphuric acid. Based on an average of 4 mt, annual sulphuric acid consumption is approximately 10 million mt, of which more than half relies on imports from the Middle East. The Middle East is both a critical global energy transportation route and a core hub for sulphur trade. The current US-Iran conflict has lasted 46 days, and local smelter sulphuric acid inventory is at low levels. Coupled with China, as a major global sulphuric acid exporter, imposing export restrictions, ex-China sulphuric acid supply has tightened further. The sulphuric acid shortage has constrained SX-EW copper output to a certain extent, creating expectations of a contraction in global copper cathode supply and providing clear bullish support for copper prices. According to SMM, SX-EW copper production in the DRC and Zambia has been gradually suffering losses recently, especially at some smaller smelters. The originally projected SMM global copper cathode balance surplus for 2026 is expected to slow down YoY. Expectations of copper cathode supply losses have strengthened, and the market is expected to gradually shift from a loose balance to a tight balance. The tightening supply-side expectations are set to provide support for copper prices. II. Easing geopolitical tensions coupled with inflation pullback push the US dollar index lower, providing support for copper prices Earlier, the escalating tensions in the Middle East continued to push up energy prices, increasing inflationary pressures. Expectations for US Fed interest rate cuts cooled somewhat, and the market gradually priced in unchanged interest rates for the full year. Recently, signs of easing emerged in the geopolitical conflict. Trump stated that the US and Iran are expected to hold talks in Pakistan within the next two days. Pakistan called for a 45-day ceasefire extension, and both sides agreed to continue negotiations, with only the time and location yet to be determined. According to sources familiar with the matter, Iran is considering temporarily suspending shipping restrictions in the Strait of Hormuz to create a favorable atmosphere for negotiations, and the US military has no plan to attack Iranian oil tankers. On April 14, Trump publicly stated that the military campaign against Iran was nearing its end, with positive signals being gradually released, The pullback in crude oil prices and the weakening of the US dollar index provided some support for copper prices. Meanwhile, the pullback in oil prices eased inflationary pressures, leaving room for subsequent interest rate cuts, and sentiment improved somewhat. III. Social Inventory Declined for Five Consecutive Weeks; Combined with Peak Consumption Season and Maintenance Cycle, Tight Supply-Demand Conditions Supported Copper Prices After the Lantern Festival, copper prices gradually pulled back, downstream consumption recovered somewhat, and SMM social copper inventories in major regions across China continued to destock from mid-March. Recently, copper prices rebounded somewhat, downstream purchasing became more cautious, and the destocking pace slowed down. As of April 13, SMM social copper inventories in major regions across China had decreased from 578,900 mt on March 9, 2026 to 299,800 mt, maintaining destocking for five consecutive weeks. China is currently entering the traditional peak consumption season. Copper scrap policies still carry certain uncertainties, and the overall operating rate of scrap utilization enterprises remains relatively low, providing some support for copper cathode rod consumption. Meanwhile, global smelters are entering a concentrated maintenance period in Q2, further tightening the supply side. The continued decline in inventory, combined with a tight supply-demand pattern, is providing some support for copper prices. Overall, the macro front and fundamentals are currently forming a degree of resonance, providing relatively positive support for copper prices. From a macro perspective, geopolitical conflicts showed signs of easing, the US dollar index pulled back somewhat, and earlier inflationary pressures were alleviated to some extent. On the fundamentals side, tightening sulphuric acid supply constrained SX-EW copper output outside China, SMM China social inventory continued to decline, and combined with relatively strong domestic fundamentals, the supply-demand pattern showed a tightening trend. However, as copper prices rebounded above 100,000 yuan/mt, downstream acceptance weakened somewhat, and recent purchase willingness also turned slightly cautious. Going forward, it is worth watching whether actual demand performance during the traditional peak season can meet expectations against the backdrop of high copper prices.

[SMM Shanghai Spot Copper] Looking ahead to next week, the Shanghai spot copper market is expected to remain under pressure. Supply side, smelters will maintain normal operations during the Qingming Festival holiday, and domestic spot copper output will continue, while imported copper will arrive successively, making spot cargo in circulation in the post-holiday market more ample. In addition, although some suppliers sold off cargo slightly during the day, with Honglu quoted at a discount of 80 yuan/mt, this did not drive overall spot discounts lower, reflecting that suppliers still have the willingness to hold prices firm at current price levels, with spot discounts receiving some support on the downside. Overall, amid the tug-of-war between expectations of ample supply and suppliers' willingness to hold prices firm, Shanghai spot copper prices against the 2604 contract are expected to remain at a discount after the holiday.

An India-US consortium has acquired CHEMAF’s copper-cobalt assets in the DRC, with plans to scale copper output significantly. The deal underscores intensifying geopolitical competition for critical mineral resources.
