[Lead Smelter Updates] It was reported that Yuguang Gold and Lead Group stated on an interactive platform that Ye Group holds the mining rights to the Shuikoushan lead-zinc mine and the Baifang copper mine, with 3 mines (the Kangjiawan mine and the lead-zinc mine both fall under the Shuikoushan lead-zinc mine mining rights) and 1 beneficiation plant, possessing an annual mining and beneficiation capacity of 860,000 mt of raw ore. Its captive mines can produce lead concentrates, copper concentrates, gold concentrates, and other mineral products, providing raw material support for the company.

SMM May 15 News: In May 2026, the global molybdenum market remained in a persistently tight supply-demand pattern, with prices extending and accelerating the upward trend seen in April. International molybdenum oxide prices kept surging at high levels, while domestic molybdenum concentrate and ferromolybdenum prices repeatedly hit new stage highs.

Zambia banned sulphuric acid exports in September 2025 and subsequently implemented a licensing policy in March this year. Zambia's Minister of Commerce, Trade and Industry Chipoka Mulenga told Reuters on Thursday that the government had authorized Chambishi copper smelter and Mopani copper mine to resume sulphuric acid shipments after local inventory had been replenished. Mulenga also said Zambia could expand export licenses if supply conditions continued to improve. Documents seen by Reuters showed that the Ministry of National Defense also authorized chemical trader Alliswell Investment Limited to ship 5,000 mt of sulphuric acid. An industry source said Mopani had not yet received an export license. Mopani, Chambishi, and Alliswell did not respond to requests for comment.

SMM Morning Meeting Minutes: Overnight, LME copper opened at $14,043/mt, touched a high of $14,077/mt in early trading, then the copper price center gradually shifted lower to probe $13,917.5/mt, followed by wild swings before finally closing at $13,986/mt, down 0.7%, with trading volume at 22,000 lots and open interest at 277,000 lots, an increase of 2,465 lots from the previous trading day, indicating bears reducing positions. Overnight, the most-traded SHFE copper 2606 contract opened at 107,250 yuan/mt, immediately touched a high of 107,320 yuan/mt in early trading, then the copper price center quickly shifted lower to probe 106,690 yuan/mt, followed by a rise amid wild swings before finally closing at 107,024 yuan/mt, down 0.35%, with trading volume at 39,000 lots and open interest at 184,000 lots, a decrease of 4,131 lots from the previous trading day, indicating bulls reducing positions.

According to Mining.com, drilling by Canadian exploration enterprise San Lorenzo Gold at the Arco de Oro target within the Salvadora project in Chile indicated that the property may host several copper-gold deposits. San Lorenzo said on Friday (8th) that drill hole SAL-10-25 intersected 102 meters of mineralization at a depth of 153 meters with a gold grade of 1.33 g/mt, including 13 meters at the same depth with a gold grade of 2.21 g/mt. Nearby drill hole SAL-09-25 intersected 59 meters of mineralization at a depth of 238 meters with a gold grade of 1.07 g/mt, including 11 meters at a depth of 270 meters with a gold grade of 3.78 g/mt. "These drill holes indicate a larger mineralization system at Arco de Oro than previously recognized," said Terence Walker, Vice President of Exploration. "We appear to be entering the upper portion of a gold-rich porphyry copper-gold system that requires follow-up drilling." Calgary-based San Lorenzo has become one of the best-performing junior exploration companies on the Toronto Venture Exchange this year, with a series of discoveries at its Salvadora project in the Atacama Region of northern Chile. The project covers more than 90 square kilometers and is located approximately 15 kilometers from Codelco's long-producing El Salvador copper mine. Infrastructure including roads and power is well-established, with access to nearby mining services. Five Targets Arco de Oro is one of five porphyry and epithermal deposit targets at the Salvadora project. Earlier this year, early-stage drilling at the Cerro Blanco target intersected gold mineralization on multiple occasions, attracting investor attention and financing. In March, San Lorenzo raised approximately $20 million through a private placement to fund further exploration at Salvadora. San Lorenzo has been steadily expanding the extent of the deposit. Two months ago, the company added 29 square kilometers near Cerro Blanco by acquiring three nearby Rubi blocks and signing an option agreement. San Lorenzo said the geological setting at Salvadora is similar to other Andean porphyry deposits in Chile. Management noted that the broad mineralization intersections and multiple targets suggest the potential existence of a large-scale copper-gold mineralization system. Assay results from other drill holes at Arco de Oro have not yet been completed, and the company will continue drilling to verify the extension of the ore body, which remains open in all directions.

McEwen Copper said on May 11 that it has secured arrangements for a $2.4 billion loan package to help finance development of the Los Azules copper project in Argentina. Total project financing is expected to reach $4 billion, alongside a planned IPO later this year. The mine is targeting first production around 2029–2030 with annual copper cathode output exceeding 200,000 tons. Rising copper prices are helping reopen financing channels for major mining projects globally.

The 2026 SMM Hong Kong Metals Forum , organized by Shanghai Metals Market (SMM) and sponsored by China Securities International as platinum sponsor, wrapped up successfully at Novotel Hong Kong Century on May 6. With over 300 registrations and 200 on-site attendees, the forum focused on the theme "New Metals Cycle: Prices, Power & Global Wrestling". The event featured keynote speeches by industry experts and SMM analysts, covering base metals, new energy materials, and strategic revaluation of minor and precious metals. Two high-level panel sessions were held, exploring hot topics such as geopolitics, supply-demand fluctuations, CBAM impacts, and market opportunities. It also served as an efficient platform for networking and cooperation across entire industry chains. SMM Opening Address SMM Chairman Adam Fan SMM Chairman Adam Fan stated in the opening address that it was a great honor to gather with elites from all sectors of the industry at this forum. The world is currently at a critical development period, and the exchange of industry ideas is not only an industry necessity but also an inevitable requirement for global development. Adam reviewed the century-long legacy of the London Metal Exchange, which has weathered nearly 150 years of global changes and industry evolution, fully demonstrating that although market structures may change, the fundamental need for risk management and reliable price discovery remains constant. At the same time, Adam candidly acknowledged that global markets are currently mired in a pattern of deep fluctuations. Geopolitical conflicts, supply chain fragmentation, and the compounding crises of energy and food, overlaid with de-globalization and rising trade protectionism, have intensified market uncertainty and inflationary pressures, posing severe challenges to global economic growth and industrial cooperation. Against this backdrop, SMM has steadfastly upheld its mission, refusing to be a bystander to the trend of industry fragmentation, and is committed to serving as a bridge for global industrial connectivity amid a landscape of division. SMM is dedicated to promoting dialogue and exchange, breaking down industry and regional barriers, and bringing together regulators, traders, and producers from around the world to discuss industry development. SMM upholds the principle of information transparency, continuously providing accurate, real-time market data to help the industry see through market fog and clarify market distortions. SMM deepens pragmatic cooperation by building a neutral and professional platform for exchange and matchmaking, driving all parties to pursue collaborative development based on shared interests and transcending political differences. Adam emphasized that information sharing and open collaboration would be leveraged to mitigate market risks and strengthen overall industry resilience, and called on the industry to seize the opportunity of this forum to jointly explore solutions, transforming current challenges into momentum for driving integrated and robust development of the global metals industry. Speech by Platinum Sponsor Wang Guangxue, Member of the Executive Committee of China Securities Co., Ltd. and Chairman of China Securities Futures Co., Ltd.

Structural Shifts: Rethinking Commodity Benchmarks in an Era of Persistent Inflation and Rivalry Speaker: Tian Yaxiong, Co-Head of R&D Department, China Securities Futures Tian shared professional research findings and cutting-edge market insights on hot topics including the market outlook for global metals and the deep impact of geopolitics on commodity trends. SMM Industry Analysis: Market Outlook and Pre-seminar Sharing for Base Metals and New Energy Materials (Copper, Aluminum, Nickel, Cobalt, Lithium, and Tin) & How SMM Empowers Your Commodity Trading & Analysis Speakers: Dr. Yanchen Wang, Managing Director of SMM Global UK Ltd.; Thomas Feng, Head of Industry Analysis at SMM Dr. Wang first analyzed the macroeconomic landscape. At the beginning of this year, the manufacturing PMIs of major economies performed quite well, actually exceeding 50%. Without the conflict, demand this year would have been quite strong. However, at the end of February, the US-Iran conflict broke out, and the International Monetary Fund subsequently revised down its global economic growth expectations. He pointed out that China's exports remain one of the three pillars that are still functioning well to date. Regarding automobile consumption, he noted that for the EV market, the positive factor for the auto industry also lies in exports. In Q1 this year, export performance was indeed very strong. If you look at EV exports alone, they actually grew nearly 160% YoY. Driven mainly by growth in global markets, he remains optimistic about the auto industry this year. In Europe, gasoline and diesel prices have risen significantly due to the US-Iran conflict, and EV demand is expected to benefit from this factor. He believes the power sector continues to maintain strong growth. Based on power grid and power generation investment data from the first two months, combined with State Grid Corporation of China's earlier announcement that fixed asset investment during the "15th Five-Year Plan" period is expected to reach 4 trillion yuan, this indicates that electricity demand will drive strong growth. State Grid Corporation of China will build more ultra-high voltage transmission projects, which will undoubtedly support aluminum demand and also copper demand. Aluminum: Wang noted that base metal prices experienced wild swings since the beginning of this year. He also discussed that China's aluminum smelters continued to raise operating rates due to favorable profitability; aluminum demand pulled back in Q1, and high prices drove inventory higher; approximately 950,000 mt of new aluminum smelting capacity in Indonesia may come online in 2026, with some investors watching Angola; and aluminum semis and wheel hub exports maintained growth in Q1. Copper: After copper prices experienced a pullback and adjustment in March, downstream procurement demand in China was rapidly released, providing strong support for copper prices to rebound. Copper prices rose sharply, with the market downplaying geopolitical risks. China's copper cathode demand was robust, and inventory continued to decline. China's copper scrap market was not truly facing a spot shortage issue. The outlook for copper cathode demand is positive. China remains dependent on copper concentrate imports. Spot copper concentrate TCs showed no signs of bottoming out. By-product revenue sustained smelter profits. He also analyzed the DRC sulphuric acid market conditions, the expected slowdown in global refined production growth, and how a refined market supply deficit should support higher copper prices. He also mentioned that the AI industry maintained strong development momentum, bringing new growth momentum to copper demand. Tin: He elaborated from the following perspectives: Myanmar tin production — slow recovery, upward trajectory, 2025-2027E; Indonesia tin ore RKAB quotas — expected to ease slightly in 2026; DRC — major mine production remained stable, but the M23 movement added uncertainty; global tin prices — supply determines the floor, macro factors drive fluctuations; the global tin market is expected to maintain a tight balance, with new mining capacity expected to be concentrated for release in 2028. Thomas Feng shared insights on nickel, cobalt, and lithium: emerging from the trough and entering a new cycle. ►New energy demand landscape: from EV popularization to energy storage deployment. First, he reviewed and provided an outlook on the global NEV market: NEV demand no longer maintains a one-sided high-growth trajectory, but instead exhibits characteristics of regional differentiation, structural divergence, and intensifying cyclical volatility; development paces in China, Europe, and the US have shown notable differences; performance trends of BEVs, PHEVs, and commercial vehicles have diverged; and the impact of inventory and price cycles on industry operations is increasing significantly. Second, in his review and outlook of the global energy storage market, he noted that the global energy storage market will remain concentrated in three key regions: China, the US, and Europe. Driven by 2030 climate goals, emerging markets such as the Middle East, Australia, and Southeast Asia are showing strong growth in demand for large-scale energy storage. Benefiting from cost advantages and improved safety performance, LFP battery market share is expected to continue climbing. ►Lithium: Reshaping the Supply-Demand Pattern in a New Cycle Global lithium carbonate market: shifting from overall surplus to structural tightness, with prices in a post-trough reassessment and recovery phase. Lithium hydroxide supply and demand maintained a tight balance: production on the supply side was driven by demand, the market share of ternary power batteries was squeezed, and room for growth was limited. The concentration of lithium resource supply declined, with marginal growth rates slowing down simultaneously. Significant demand growth drove the continued expansion of resource projects. ►Nickel: Navigating Policy Changes and Narrowing Oversupply Indonesia's nickel ore HPM adjustment: aimed at enhancing the economic value of non-nickel resources. The discussion covered scenario analysis of nickel ore prices following the implementation of the new policy, and the impact analysis of nickel ore benchmark price adjustments on MHP full costs. Indonesia's nickel ore RKAB quota: a tight balance is expected to set the tone for 2026. Global primary nickel is expected to remain in persistent oversupply. Regarding the logic behind refined nickel price trends, it was noted that policy and macro factors jointly amplified price fluctuations, while cost support elevated the long-term price floor. ►Cobalt: Shifting from Surplus to Shortage after the DRC Export Ban——Long-Term Uncertainty Remains Following the DRC policy announcement, cobalt product prices in China rose rapidly. However, high prices suppressed downstream demand, putting prices under pressure. Starting from H2 2025, the Chinese market continued destocking. Amid raw material shortages, enterprises began using MHP and recycled materials as production substitutes. MHP and recycling are expected to continue growing rapidly, effectively bridging the cobalt hydroxide gap. Cost pressure transmitted in both directions: LCO doping/ternary substitution restarted, and consumer cobalt demand is expected to decline by 10%. As persistently high cobalt prices suppress demand, if China secures 90% of the DRC quota, supplemented by MHP and recycling supply, inventory buildup could occur as early as 2026. Panel Discussion: Global Metals Market Outlook——Geopolitics Disruption, Macro Cycles and the Return of Commodity Volatility •Copper and Aluminum Price Rise, 2024-2026 •Precious Metals Storm: Silver Swung Wildly, Gold Hit Record Highs — Interest Rate Cycles, Safe-Haven Demand, and Industrial Logic •Precious Metals and Industrial Metals: Are Commodities Entering a New Cycle •Focus on Critical Minerals: Emerging Region Supply Rise and Policy Shifts, Green Transition Co-Shaping a New Narrative •Chinese Market: The 15th Five-Year Plan Moderator: Yanchen Wang, Managing Director, SMM Global UK Ltd. Panelists: Yahong Tian, Co-Head of R&D, CITIC Futures Henry Van, Head of Industrial Metals Analysis, Trafigura Sharon Ding, Head of China Basic Materials, UBS Justin William Hughes, Commodity Derivatives Distribution, Optiver Xie Shaobo, Head of China, Appian Mining Fund & independent non-executive Director, Zijin Gold International Panelists noted aluminum has great upside—its 10% price rise lags its 4%-5% supply contraction (vs. oil’s 60% price surge on 10% supply drop), with valuation recovery incomplete. They were more optimistic about copper demand, driven by real downstream demand rather than speculation; aluminum semis’ upside is underappreciated due to high oil prices. Long-term, copper and gold are key for mining investment, with scarce high-quality copper mines and solid gold fundamentals. They also discussed US tariffs, China’s metal demand resilience and overseas mining investment. Overseas mining success hinges on resource-to-reserve certainty; West Africa, Latin America, DRC and Zambia are new hotspots, while Australian/Canadian listed miners are undervalued. Enterprises must plan prudently based on risk tolerance. Geopolitical conflicts (e.g., Iran) may trigger energy crises, but current inflation control and China’s high metal consumption share weaken demand impact. Long-term, energy crises will boost electrification, expanding copper/aluminum demand. Investment depends on risk appetite and fundamental grasp. SMM Industry Analysis: Strategic Re-valuation of Minor Precious and Minor Metals in 2026 — The Case of Silver and Tungsten Silver: Market Supply-Demand Balance and Macroeconomic Volatility: Evolution and Shift in Industrial Demand, Particularly Driven by the PV Sector Tungsten: Strategic Status Upgrade - Supply Constraints and High-End Demand Driving the 2026 Price Rally Speaker: Juno Zhu, Senior Analyst of Minor and Precious Metals, SMM Juno shared insights on the strategic revaluation of tungsten and silver. Tungsten: Tungsten prices have surged over 500% since 2025; China holds over 50% of global tungsten reserves, contributes nearly 80% of global production, and possesses a complete industrial value chain; China's tungsten supply constraints in 2025: H1 mining quotas declined 6.45% YoY; global new project stagnation: limited capacity expansion in 2026, with ex-China mine development cycles of 3–5 years; domestic tungsten downstream applications: significant growth in cutting tools and PV tungsten wire in 2025; European market: persistent raw material shortages, with Rotterdam tungsten prices surging since February 2025; China's tungsten product exports: transitioning from primary products to deep-processed products; SMM analysis: the tungsten market supply-demand gap is expected to persist but narrow in 2026; prices are expected to consolidate at highs after overheating cools. Silver: Silver price fluctuations in 2026: an unexpected surge from Q4 2025 to Q1 2026, where frenzied investment demand and capital liquidity completely overshadowed the impact of the industrial off-season. Shift in trade dynamics in Q1 2026: SGE-LBMA premiums reversal and a surge in imports. Demand spike in Q1 2026: the PV industry started with a recovery, and an investment boom generated a phased demand peak. PV market outlook: policy shifts in 2026 are expected to curb demand growth, with overall silver consumption remaining stable. Silver demand outlook for 2026: industrial fundamentals provide support, while investment surges serve as a tactical highlight. Silver supply outlook for 2026: mild annual growth and an expanding secondary supply share are expected to drive a tight balance in the market. Market outlook: short-term trends are expected to revert to industrial fundamentals, while the medium and long-term trajectory is expected to fluctuate at highs driven by safe-haven demand. Panel Discussion: Metals in a Fragmented World: Trading Opportunities in the Age of Instability (Physical Trading and Hedging) •Shifting Liquidity Landscape across LME, CME, and SHFE •Shipping Risks and Sanctioned Metals: Implications for LME Inventory Structure •How European CBAM is Reshaping Global Metals Trade Flows •Is the Metals Market Entering an "Era of Geopolitical Risk Premiums" •Internationalization of SHFE & GFEX: Opportunities and Challenges for Global Investors Moderator: Jean Tang, Commercial Director, SMM Panelist: Anant Jatia, Founder and Chief Investment Officer, Greenland Investment Management Bella Yu, General Manager of Marketing Department, Liyang Unilink E-commerce Co., Ltd. David Wilson, Director of Commodity Strategy, BNP Paribas Duncan Hobbs, Research Director, Concord Resources Nicholas Snowdon, Head of Metals and Mining Research, Mercuria Energy Trading SA Sabrina Qian, Director of Geared broking desk, IFCHOR GALBRAITHS Anant Jatia stated: CBAM represents a major policy shift in Europe's metals sector. It is not merely about raising trade costs, but will profoundly reshape global metal trade flows and pricing logic. CBAM officially took effect in January this year, initially covering categories such as steel and aluminum semis, with its core mechanism incorporating carbon emission intensity costs into Europe's metal pricing system. High-carbon-emission producers will need to bear additional carbon allowance costs, significantly weakening their export competitiveness to Europe, while green capacity powered by clean energy will gain a clear advantage in the European market and capture greater market share. Following the policy's implementation, the landed cost of metals in the European market will rise, sustaining a long-term regional premium similar to the aluminum premium structure in the US market. Compared with the market differentiation among LME-registered brands following CBAM's implementation, what deserves more attention are the entirely new market opportunities it creates. By sourcing low-carbon, high-quality materials, market participants can potentially capture green premiums, while the mechanism will also transform metal trading models and the global trade flow landscape. The panelists also discussed the changing liquidity landscape across LME, CME, and SHFE. They noted that liquidity in the commodity market is becoming increasingly fragmented, with copper and other products now tradable across multiple global futures exchanges. Price discovery is no longer concentrated in a single market, and the traditional pattern of one market leading gains and others following has reversed, with multi-exchange rotation driving price movements becoming the norm. Factors such as geopolitical policies and tariff adjustments have given rise to regional pricing divergence, with price movements in some markets increasingly driven by capital flows and sentiment. Policy and geopolitical events have also significantly affected the spread between futures and spot prices of metals, creating opportunities for cross-market arbitrage. Meanwhile, policies related to critical minerals supply security, regional supply shocks, and geopolitical disruptions have widened the dislocation between regional fundamentals and price signals. The metals market has entered a window of structural arbitrage opportunities, and this trend is expected to persist. Cross-market arbitrage continues to provide liquidity support to exchanges, a phenomenon broadly observed across both industrial and precious metals. In addition, the panelists engaged in in-depth discussions on the differences between exchange liquidity and industrial liquidity, as well as factors influencing metal price trends, including fundamentals, geopolitical developments, energy costs, and commodity transportation costs. Opening Remarks for Coffee Break Xu Tao, CEO of CSCI In his address, Xu Tao stated that Hong Kong serves as a vital hub in the global metals pricing and trading system, playing a key role in the aggregation of LME delivery resources and the internationalization of RMB-denominated commodities.

Rio Tinto stated that it expects its copper production to increase by approximately 13% by 2030, mainly driven by growth from the Oyu Tolgoi project in Mongolia and the Kennecott operation in the United States. The company also noted that global copper mine development continues to face challenges including lengthy permitting processes and slow supply additions. As demand from AI, electrification, and energy transition sectors continues to grow, major mining companies are accelerating global copper resource development and long-term supply expansion strategies.

Driven by recovering risk appetite and China's peak demand season, copper prices both in China and abroad bottomed out since late March. However, as SHFE copper returned to the 100,000 level, the tug-of-war between longs and shorts increased, and futures prices shifted to range-bound consolidation. After the Labour Day holiday, copper prices quickly resumed their upward momentum. Today, prices opened higher with a gap and continued to rise, with SHFE copper just one step away from the record high set at the end of January, while LME copper hit a new closing high. What is fueling such strong confidence behind this rally? Deepening Ore-Side Vulnerability Intensifies Supply Disruption Concerns Since the suspension of First Quantum's Cobre Panama copper mine at the end of 2023, spot TC for copper concentrates in China has been caught in an endless downward spiral. Falling from around $80/dmt at the end of 2023, it largely dropped to single-digit levels and moved sideways in 2024. Entering 2025, it further plunged into negative territory, mainly due to successive production disruptions at world-class copper mines including Ivanhoe Mines' Kakula, Codelco's El Teniente, and Freeport's Grasberg mine in Indonesia. Entering 2026, global major copper ore supply growth remained limited, and the ore tightness showed no improvement. The latest data showed that spot TC for copper concentrates in China had fallen below -$90/dmt. With long-term contract TC at zero and spot TC declines accelerating, domestic smelters' production profits mainly relied on surging sulphuric acid prices and firm by-product prices of gold, silver, and other metals to compensate. It was reported that current sulphuric acid revenue could already cover smelters' procurement costs for copper concentrates and part of the processing costs, enabling domestic smelters to maintain relatively high operating rates, and the ore tightness had not yet notably transmitted to the smelting side. It is worth noting that sulphuric acid is not only a by-product of pyrometallurgy but also a core production material for SX-EW copper. For every 1 mt of copper produced, 5–6 mt of sulphuric acid is consumed. Sulphuric acid costs account for 40%–50% of total SX-EW copper production costs, and SX-EW copper production accounts for approximately 20% of global mine copper production. Since the beginning of this year, sulphuric acid prices surged sharply due to multiple factors, and ex-China sulphuric acid supply was periodically disrupted, raising concerns that copper supply in some countries could be affected. Focusing on the reasons behind the sulphuric acid price surge: on one hand, since the escalation of the Middle East conflict on February 28, shipping through the Strait of Hormuz has been broadly restricted and has recently faced a dual blockade by Iran and the US. Sulphur exports from the Middle East have been impacted, with the DRC and Zambia being the most concentrated SX-EW copper producing regions that are highly dependent on sulphur imports from the Middle East. As sulphur supply has been constrained, sulphuric acid prices have naturally risen in tandem, not only raising local SX-EW copper production costs but also potentially triggering further production cuts if the Strait of Hormuz blockade continues and sulphur disruption risks escalate. On the other hand, to prioritise domestic spring ploughing phosphate fertiliser production and support new energy industry expansion, China has imposed a phased ban on sulphuric acid exports according to industry sources. Chile has a relatively high dependence on Chinese sulphuric acid, with SX-EW copper accounting for around 20% of its output, and the market is also concerned that Chile's SX-EW copper production may be affected. In addition, against the backdrop of an already fragile copper ore supply, frequent news shocks from outside China recently have undoubtedly intensified market concerns. Last week, market rumours suggested that the full restart of Indonesia's Grasberg copper-gold mine, which declared force majeure in September last year, had been delayed by one year, driving SHFE copper sharply higher in the afternoon of 8 May. However, according to the latest update from Freeport-McMoRan, the company still expects Indonesia's Grasberg copper-gold mine to fully resume production by the end of 2027, reaffirming the plan outlined last month and refuting reports that production resumptions could be delayed to 2028. Furthermore, yesterday Peru declared an emergency energy decree due to a natural gas pipeline explosion. Peru's copper production reached 2.63 million mt in metal content last year, ranking third globally. Copper mining and smelting are relatively sensitive to power stability, and the market is concerned that Peru's energy strain may disrupt local copper supply. Overall, China's copper cathode production remains relatively stable, but some major global miners lowered their full-year production guidance in Q1, the ore tightness persists, sulphuric acid supply — a core raw material for ex-China SX-EW copper — is constrained, and there are multiple supply disruption themes on the copper supply side, which can easily boost copper prices once the macro front stabilises. Global Copper Visible Inventory Divergence: China Destocking Provides Support Last year, driven by the US government's threat to impose additional tariffs on imported copper, global copper continued to flow into the US, causing COMEX copper inventories to accumulate continuously while copper inventories in non-US regions remained low, providing sustained support for copper prices. In February this year, the US Supreme Court struck down most of the tariff measures introduced by the Trump administration in 2025. The Trump administration subsequently turned to Section 122 of the Trade Act of 1974 to push new global tariff policies. On 7 May, the US Court of International Trade issued a ruling stating that the legal basis for imposing a 10% global import tariff was invalid. The tug-of-war between US courts and the Trump administration over tariffs has continued recently, but the market has certain expectations that the US may subsequently impose additional tariffs on imported copper. Under such expectations, the price spread between COMEX copper and LME copper has shown a slight strengthening trend recently, meaning copper in LME warehouses still has the potential to flow to the US. Specifically, COMEX copper inventories have continued to rebound since mid-April, rising from around 590,000 mt to the latest 620,000 mt, again hitting a multi-year high. Correspondingly, LME copper inventories pulled back from around 400,000 mt in mid-April, declining to 397,700 mt on 6 May. They have rebounded with fluctuations recently, but overall inventories have not exceeded the over-12-year high set in mid-April. SHFE copper inventories fell for the eighth consecutive week, currently dropping to 181,300 mt, the lowest since the beginning of the year. Data source: Webstock Inc. Overall, on the macro front, there are currently disagreements in US-Iran negotiations, but both sides continue the ceasefire with no recent signs of escalation in conflict. Energy prices pulled back from late April levels, inflation concerns eased somewhat, the US dollar index was in the doldrums, and combined with the AI boom lifting global stock markets, market risk appetite was moderate, providing a fertile ground for copper prices to strengthen. Focusing on copper's own fundamentals, inventories outside China remained elevated, but significant prior destocking of China inventories provided support. The ore tightness was difficult to reverse, and supply-side narratives were abundant, meaning copper prices may still hold up well. However, it is worth noting that the Middle East situation remains the biggest macro variable, and the policy path following the Fed Chairman's power transition also deserves close attention.
