SMM Analysis | June 30 marks a critical milestone in the U.S. Section 232 copper investigation. Will refined copper tariffs proceed as expected? Whether the outcome is a broad tariff, targeted measures, or a delay and exemption, the decision could reshape the COMEX–LME arbitrage, U.S. physical premiums, global copper trade flows, and regional supply dynamics.

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.

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.

[SMM Analysis]: Copper-related Policy Shifts Across the Americas: Copper is no longer merely an industrial metal — it is rapidly emerging as a strategic resource. From mining policy reforms in Chile and Peru, to the U.S. Section 232 investigation and the strengthening of North American critical minerals strategies, copper policies across the Americas in 2025–2026 are set to exert profound influence over global copper supply-demand balances, smelting dynamics, and copper price volatility.

Chile’s government announced on May 14 that Bernardo Fontaine will become the new chairman of state-owned copper giant Codelco. The leadership change comes as the company faces scrutiny over rising debt, budget overruns, and unusual production fluctuations reported late last year. Authorities have ordered an external audit and investigation into recent output inconsistencies. As the world’s largest copper producer, governance changes at Codelco are being closely watched by global copper markets.

The 2026 SMM London H1 Seminar concluded on April 29 with great success, bringing together global metals and commodities leaders for a day of high-level dialogue and actionable insights. The seminar drew over 160 valid pre-registrations and more than 100 on-site attendees, gathering core practitioners, senior experts, research scholars and institutional representatives across the global non-ferrous metals industrial chain. Centered on copper, aluminum, lead and zinc, the event delivered in-depth insights into current industry performance, supply-demand shifts and future market outlooks. It also featured two high-level panel sessions with distinguished guests, who exchanged views on key industry highlights such as geopolitical impacts, global trade restructuring, cross-market arbitrage and divergent commodity fundamentals. The event comprehensively reviewed the macro backdrop of commodities as well as opportunities and risks in base metals, offering professional references and forward-looking insights for global non-ferrous market participants. SMM Industry Analysis: Copper, Aluminum, Nickel, Lead & Zinc Geopolitics and Metals: Pricing the New Global Risk Premium How rising geopolitical tensions are reshaping global supply chains, macro risk, and base metal price formation. Dr. Yanchen Wang, Managing Director of SMM Global UK Ltd., provided analysis on macro trends and the aluminum and nickel markets. From a macro perspective, he noted that global economic uncertainty has intensified, with the IMF cutting global GDP growth forecast. China's exports may serve as a key economic pillar in 2026. Power sector investment increased significantly from January to February 2026. The State Grid Corporation of China will ramp up investment during the "15th Five-Year Plan" period. In terms of the aluminum market, Chinese smelters saw improved profitability and higher operating rates. Weak demand in Q1 combined with rising aluminum prices drove inventory to rise. Outside China, new aluminum capacity additions in Indonesia in 2026 are expected to be substantial, with SMM estimating approximately 950,000 mt of new aluminum smelting capacity potentially coming online in Indonesia in 2026. Angola is attracting Chinese investment thanks to its hydropower advantages. In the nickel market, given the Indonesian government's tightening of quotas, SMM estimates Indonesia's RKAB supplementary quotas this year at approximately 15%-20%. In terms of supply outside China, constrained by a lack of new projects, imports from the Philippines are expected to remain at around 19 million mt. Considering the impact of the rainy season on production, the market is expected to maintain a tight balance. Shairaz Ahmed, Principal Market Analyst & Client Advisor at SMM, shared insights on the global copper market. He noted that global copper cathode demand will continue to grow from 2025 to 2030, with demand potentially reaching around 32 million mt by 2030 in an optimistic scenario. China's copper concentrates still rely on imports, and global copper concentrates supply will remain tight from 2026 to 2028, with the downward trend in spot TC not yet over. Meanwhile, global copper cathode production growth will slow down in the future, and the market will most likely fall into a supply deficit from 2027 to 2030, providing long-term support for copper prices. Yueang He, Senior Lead & Zinc Analyst at SMM, interpreted the lead-zinc market trends for 2026. Looking at the global zinc concentrates market in 2026, he stated that although production in China, Africa, and some projects continues to ramp up, production cuts at large mines are suppressing overall supply, with China's zinc concentrates production estimated to be up 4.8% YoY to 3.95 million mt in 2026; European smelting, affected by electricity prices fluctuations, may see selective minor production cuts of 60,000-100,000 mt. Overall, the zinc concentrates market in and outside China will maintain a tight balance in 2026, with refined zinc showing a surplus in China and a deficit ex-China. In terms of lead market, he stated that global lead mine supply is gradually recovering, but the concentrates market remains tight, and TC is unlikely to rebound significantly in the short term. He estimates that the loose supply situation in the global refined lead market will persist until 2028, with high visible inventory on both exchanges combined with slightly soft battery demand in China limiting the upside room for lead prices. Panel Session — Positioning and Price Signals: What Are Commodity Markets Telling Us? Understanding market positioning, inventory signals, and cross-market arbitrage. Moderator: Shairaz Ahmed, Principal Analyst & Client Advisor at SMM Panelists: David Lilley, Director and Co-CIO at Drakewood Capital Management Limited Maruis Van Straaten, Metals Research Analyst at Squarepoint Gregory Shearer, Head of Base Metals and Precious Metals Strategy at J.P. Morgan Loic Jonchery, Base Metals Trader at Gunvor The panelists focused on current mainstream cross-market arbitrage strategies, emphasizing the need to closely track premiums and futures price spreads across various commodities, while comparing price spread performance across upstream and downstream categories such as cathode materials, scrap, and intermediate products, leveraging signals to identify arbitrage opportunities. The current market is subject to multiple influences including policy constraints, supply adjustments, and changes in industry rules, with the overall landscape becoming increasingly fragmented. China's policies have imposed a supply ceiling, compounded by industry framework adjustments and lengthy implementation cycles, keeping small and medium-sized enterprise operations and the supply side persistently tight, increasing market friction, and creating significant uncertainty in arbitrage trading. In this complex environment, price spread fluctuations have amplified and ranges continued to widen, with enhanced trend continuity in underlying markets; combined with cross-regional approval processes and circulation restrictions, traditional arbitrage logic has broken down and trade execution difficulty has increased. At the sub-sector level, the copper market attracted high attention, while structural distortions in nickel and other categories became prominent, making conventional arbitrage and sales models difficult to execute consistently; quality arbitrage opportunities concentrated among entities with balance sheet advantages, while ordinary participants became more cautious in decision-making, with overall trading behavior turning more conservative. Overall, the guests believed that there is no universally applicable, low-risk cross-market arbitrage strategy in the current market. Logic across different sub-markets has diverged significantly, and conducting related trades requires thorough assessment of policy, circulation, and fundamental risks. Panel Session: Superpowers and the Battle for Base Metals Moderator: Dr. Yanchen Wang, Managing Director of SMM Global UK Ltd. Panelists: Natalie Scott-Gray, Senior Metals Analyst, Middle East, North Africa and Asia, StoneX Max Layton, Global Head of Commodities Strategy, Citi Helen Amos, Managing Director and Commodities Analyst, BMO Capital Markets Amy Gower, Executive Director, Head of Metals and Mining Commodities Strategy, Morgan Stanley Amy Gower stated that since H2 last year, they have held a structurally bullish view on aluminum fundamentals: China's aluminum capacity is approaching its ceiling, and combined with expectations of incremental supply from Indonesia, the bullish logic for the aluminum industry is concentrated in H2. Currently, supply-side tightening in the aluminum market has gradually materialized, but the tightness has not been fully reflected in futures prices, and is instead more evident in strengthening spot premiums. Year-to-date, three-month aluminum has risen 18%, with European spot premiums at 27%. In addition, the guests noted that due to geopolitical factors, countries are increasingly prioritizing self-sufficiency and controllability of critical material supply chains, rather than relying on globalized supply allocation. Combined with various policy interventions, the previously freely flowing global commodities market is gradually moving toward regionalization and localized fragmentation. On the trade front, markets have become more unpredictable, and understanding the market is crucial. Some guests mentioned that interest rate trajectory is a key variable, and they expect that after interest rates decline from 2027 to 2028, supply-demand and inventory dynamics will further materialize. Meanwhile, upgraded supply chain governance and the normalization of strategic reserves across countries will provide long-term support for commodities price resilience.

On April 16 (Thursday), the DRC, through a state-backed marketing agency, increased the volume of copper it plans to sell to the US to 500,000 mt, a fivefold increase from its initial commitment in January. As first reported by Semafor, the deal was led by state-owned mining company Gécamines, with sales conducted through a joint venture with Mercuria Energy Group and backed by the U.S. International Development Finance Corporation. The deal aimed to sell copper produced from Gécamines' minority stakes in major operations including Kamoto Copper Company and Tenke Fungurume Mining. The expanded agreement underscored the DRC's growing influence in the global copper market while intensifying competition for control over critical minerals supply chains. The Kinshasa government is seeking to convert passive shareholdings into direct revenue and gain greater commercial control. Gécamines has been working to convert its stakes in some of the country's largest mines into physical copper that can be sold independently. Its holdings include Glencore's Kamoto Copper Company and Tenke Fungurume, operated by Chinese enterprises — one of the world's highest-grade copper-cobalt deposits. Although the partnership aimed to enhance transparency and control, Mercuria remained the seller of record while Gécamines established its internal trading division. Analysts noted that this transformation required substantial investment in financing, insurance, and risk management, as well as access to physical markets. The DRC's copper production surged to 3.5 million mt in 2025, consolidating its position as the world's second-largest supplier after Chile. The production growth was driven by record copper prices and surging demand fueled by the expansion of EVs, renewable energy, and data centers. (Wenhua Composite)

Workers at Glencore’s Townsville copper refinery in Queensland are planning a strike after nearly a year of unsuccessful wage negotiations. The industrial action could disrupt refinery operations and affect copper supply chains. Analysts say labor disputes add further uncertainty to the global copper market.

SMM Morning Brief: Overnight, LME copper opened at $13,104.5/mt, then its center moved downward to a low of $13,003.5/mt.
