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. Wang stated that as a vital bridge connecting the capital market and the real economy, China Securities has always been committed to serving the high-quality development of the metals industry. Leveraging the comprehensive financial strengths of CITIC Group, the company has built a full-chain integrated service system covering securities, futures, investment, and research. The company has been deeply engaged in the commodities sector, continuously providing forward-looking research to anticipate market trends, utilizing futures instruments to build robust risk barriers, and empowering industrial upgrading through capital services. It will fully leverage CITIC Group's full-license resource advantages and the strategic value of Hong Kong as an international financial center to continuously strengthen its cross-border comprehensive financial services capabilities. The company aims to tailor integrated risk management and asset allocation solutions at home and abroad for enterprises across the metals industry chain, precisely helping enterprises hedge against price fluctuation risks, and enabling them to operate steadily and advance with high quality in complex market environments. 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.
