From June 3 to June 5, Indonesia Critical Minerals 2026 was held at the Pullman Jakarta Central Park in Jakarta, Indonesia. The conference was organized by Shanghai Metals Market (SMM) and co-organized by the Indonesia Nickel Miners Association (APNI) , the Ministry of Foreign Affairs of the Republic of Indonesia , the National Economic Council of Indonesia , and MMR , in a strategic partnership with the Jakarta Futures Exchange . The conference featured six dedicated forums: the main forum, the nickel and cobalt forum, the tin forum, the coal & energy transition forum, the aluminum forum, and dedicated sub-forums, attracting 3,500+ attendees from 45 countries and regions worldwide, featuring more than 120+ speakers sharing insights on market prices, supply-demand patterns, industry policies, low-carbon development, and ESG development, etc. Conference Background of Tin Forum In 2022, both LME and SHFE tin annual prices closed lower, and the market at the time may not have anticipated that this would serve as the prelude to a three-year upward cycle. From 2023 to 2025, tin prices recorded three consecutive years of gains, with both LME and SHFE tin surging over 30% in 2025. Entering 2026, the upward trend has continued, with tin prices hitting a new record high and becoming one of the most closely watched metals in the industrial metals market. However, this rally has not been smooth. In the past two years, tin prices have fluctuated significantly within an upward channel, driven by deep adjustments in global supply-demand patterns, especially multiple disruptions on the supply side. On the demand side, emerging sectors such as AI servers, PV welding strips, and NEVs have rapidly risen, coupled with a recovery in consumer electronics, continuously highlighting tin's strategic value in high-end manufacturing and steadily expanding rigid demand. On the supply side, global tin resources are highly concentrated, production resumptions in Myanmar have fallen short of expectations, some ex-China mining areas have been disrupted by geopolitical factors, and Indonesia—a key link in global refined tin supply—has seen its industrial policy adjustments become a critical variable affecting market expectations. Reviewing Indonesia's tin industry policy, the past two years have shown a clear trajectory of "standardizing and regulating, tightening exports, and promoting downstream development." In 2024, the Mining Work Plan (RKAB) was adjusted from an annual to a three-year basis, and exports experienced temporary fluctuations during the policy transition. In 2025, Indonesia further strengthened governance over illegal mining, shutting down some illegal tin mines, cracking down on smuggling activities, and adjusting tin ore royalty fees, leading to higher production costs. Entering 2026, the policy direction has become clearer, with studies on restricting refined tin exports, lowering export quotas, and plans to raise tin royalty tax rates, promoting the transition from resource exports to high value-added processing. These adjustments are reshaping the rhythm and trade patterns of the global tin supply chain. As an important platform connecting the global tin industry chain with the Indonesian resource market, the Tin Forum focuses on the latest developments in Indonesia's tin policies, the evolution of the global tin supply-demand pattern, price trend analysis, and industrial cooperation opportunities. It brings together government officials, industry experts, miners, smelters, and downstream end-user representatives to jointly explore new opportunities in the global supply chain amid the transformation of Indonesia's tin industry.

Miller Esq, Strategic & Defense Metals Specialist/Director, Mission Critical Metals, Mission Critical Metals Keynote Speech: The Development Trend of the Tin Market in China Speaker: Zheyu Zhang, Tin Market Analyst, Marketing Department, Yuntin (Honghe) Investment Development Co., Ltd. Keynote Speech: Opportunities and Challenges for Smelters Under Indonesia's New Tin Industry Policies Speaker: Yazid Kanca Surya, Chief Executive Officer, Jakarta Futures Exchange Fragmented Global Supply Chain System Reshaping of the Geopolitical Landscape : Trade disputes and geopolitical tensions are profoundly altering traditional commodity trade patterns. Industrial Security :Countries are increasingly prioritizing long-term stable supply of strategic resources over short-term price advantages. Focus on Critical Minerals : Tin’s industry role is no longer isolated; it has become a core issue in the global energy transition and high-end manufacturing sectors. Evolution of the Tin Market The industry is entering a new phase where credibility is as important as capacity. Promoting Downstream Industrialisation (Hilirisasi) •Historical Development Background: Indonesia has long been dominated by the supply of primary processed products, with most downstream value addition achieved outside China. • Strategic Goals : Indonesia is adjusting export policies, trade management, and supply chain oversight to retain high-value-added industries within the country. Strengthening regulation and cracking down on illegal mining are not punitive measures, but rather efforts to build a transparent system to help the local area vigorously promote the development of downstream industries. Smelters Under Pressure Upstream uncertainties: Illegal mining disrupts the market, raw material supply fluctuates, and price trends are difficult to predict. Downstream market requirements: Strict compliance standards, full transparency in raw material traceability, and continuously rising screening thresholds for buyers. Market Volatility Intensifies The uncertainty in the current operating environment has increased significantly. Enterprises must not only cope with production risks, but also simultaneously address the multiple pressures arising from external shocks and rising operating costs. Investment Barriers in Deep Processing Keynote Speech: Deepening Downstream Diversification, Joining Hands to Foster Long-term Prosperity Guest Speaker: HARRY BUDI SIDHARTA, S.T, MM., Vice President Director, PT Timah (Persero) Tbk Keynote Speech: Challenges and Opportunities for China's Tin Industry amid Global Tin Ore Supply Changes Guest Speaker: Huanbo Qin, Market Analyst, International Tin Association China Keynote Speech: Analysis of Global Tin Price Trends and Future Outlook Speaker: Vicky Qiao, Senior Analyst, Shanghai Metals Market Price Trend Overview Price Review: Amid macroeconomic and geopolitical disruptions, market fundamentals have provided structural support Key Points: Tight mine-side supply has established a long-term price floor, while macro liquidity has primarily driven price fluctuations. Tin Resources and Mine Supply Landscape Supply elasticity is limited, accompanied by a high geographic concentration of reserves; the global static mine life is less than 15 years. Rising mine production alongside shrinking global resources has accelerated reserve depletion in producing countries. DRC: Output from major mines remained stable; however, M23 militant activities increased market uncertainty. ►Risks 1. The M23 armed conflict has spread to the Masisi region east of the Bisie mine and the Goma border crossing between the DRC and Rwanda, directly disrupting the original tin ore transportation route via Goma to Dar es Salaam. 2. To mitigate conflict risks, security at the Bisie mine has been reinforced, and freight routes have been adjusted northward to reroute through Uganda, ultimately destined for the port of Mombasa in Kenya. Nevertheless, market concerns persist that further spread of the M23 conflict could disrupt normal production operations at the mine. 3. The DRC recently experienced an Ebola outbreak, with confirmed cases concentrated in Beni and Bunia, areas adjacent to Uganda. Strict disease prevention measures have been implemented at both the mine and along transportation links; Bisie's mining and freight activities have yet to be affected by the pandemic impact. However, the market remains apprehensive about the local mineral supply outlook. Myanmar's Man Maw Tin Mine: Production Resumptions Hindered • 90% of Myanmar's tin ore production is concentrated in Wa State. To ensure rational resource extraction and stable regional development, Wa State suspended all tin ore mining starting in 2023, with new mining permits only reissued in July 2025. Due to the local rainy climate, the mine pits accumulated significant water during the suspension, making drainage the primary challenge upon work resumption. As the water accumulation issue affected multiple pits, the cost-sharing arrangements for drainage among mining enterprises were long delayed and never finalized. The resulting obstruction of drainage work has directly constrained the mine's production resumption progress. •In February 2026, the local government issued detailed rules clarifying the cost-sharing standards for drainage, and the Wa State tin mine immediately began resuming production. •Currently, strict approval and control of civilian explosives in Myanmar, compounded by disruptions to mining and logistics caused by the rainy season, have led to progress in local production resumptions falling short of expectations. Full resumption is expected only by 2027. The number of new tin mine projects globally is scarce, with generally low ore grades and lengthy development-to-production cycles. New projects generally have low ore grades, posing upside risks to future mining costs and increasing operational difficulty. Only three new projects have grades above 1%. Lower ore grades mean that more raw ore must be processed to produce the same amount of tin metal. The future supply landscape will be markedly differentiated, with total planned and under-construction projects reaching 173.5 kt in capacity, and just four major projects accounting for over 67%. Global supply will be highly dependent on these core mine projects, while five new projects in Australia can only bring a small incremental increase with limited impact. Global Tin Ingot Supply The high concentration of primary tin smelting capacity limits the global supply elasticity of tin ingots. Keynote Speech: Achieving the Trading and Risk Hedging of Pure Tin Ingots Through the Standardized Trading Mechanism of the Futures Market – Commodity Futures Trading Regulatory Authority Guest Speaker: Ima Siti Fatimah, Head of the Commodity Futures Trading Development Bureau, Ministry of Trade of the Republic of Indonesia Keynote Speech: Under the Drive of Geopolitical Policies: Global Strategic Metal Tin Trade Restructuring, Breakthroughs in North American Secondary Production, and New Logic in Solder Consumption Guest Speaker: Joseph G. Miller Esq, Strategic & Defense Metals Specialist/Director, Mission Critical Metals, Mission Critical Metals ► Securing Supply: US Plan to Reshore Critical Metal (Tin) Capacity • Lessons drawn from COVID-19 and World War II. • No primary tin capacity currently exists in North America: no tin ore mining operations, no tin ore smelting capacity. • The US secondary tin market is regionally fragmented. • The US government supports the Nathan Trotter primary/secondary tin smelter. • The Trump administration has made multiple investments in the critical metals sector. • Security situation in the DRC and surrounding regions. ► Data Center Tin Consumption Estimates How much tin is consumed per gigawatt of installed data center capacity? • Servers, GPUs, network systems: 500–1,500 mt. • Power systems, switchgear: 100–400 mt. • Control devices, communication equipment, cooling systems: 50–200 mt. • Tin usage per gigawatt of installed AI data center capacity is approximately 1,200–1,500 mt. Additionally, the speaker noted: the PV industry's annual tin consumption is about 25,000 mt, with average annual new installations of around 30 GW, corresponding to tin demand of 36,000–45,000 mt. Keynote Speech: Due Diligence in the Indonesian Tin Sector: A Tradition of Early Adoption and Pathways for ESG Leadership Guest Speaker: Josue Ruiz, Director of Facility Engagement, Responsible Minerals Initiative Keynote Speech: Malaysian Tin Mine: Market Breakthrough and Global Expansion from the Perspective of Critical Minerals Guest Speaker: DATO DEREK TENG, Director of the SETARA JELITA SDN BHD, President of the MALAYSIA MARITIME SILK ROUTE RESEARCH SOCIETY Critical Minerals in the New Era Strategic Positioning and Core Applications of Tin National Strategic Cornerstone: Listed in the “Critical Minerals List” by many countries, it holds an irreplaceable core position in securing national resource security and maintaining the resilience of global supply chains. Modern Industrial Lifeline: The core raw material for electronic solder manufacturing, it supports semiconductor packaging, PCB circuit boards, and other electronic information industries, serving as the “industrial monosodium glutamate” of modern manufacturing. Frontier Technology Engine: Empowering emerging technologies such as 5G communications, NEV batteries, PV modules, and AI chips, it drives the dual transformation of the digital economy and green transition. Tin: The “Industrial MSG” Driving High-Tech Industries ► A Core Member of the Global Critical Minerals System U.S. Official Designation: According to the U.S. Geological Survey (USGS) “2025 Critical Minerals List,” tin is formally listed as a critical mineral, regarded as a strategic resource vital to national economic development and national security. Global Industry Consensus: In the mineral assessment systems of the EU and other developed economies, tin also occupies a core position. It is an indispensable “emerging cornerstone mineral” supporting the global digital economic transformation and the upgrade of the new energy industry. The global tin application structure in 2025 is very clear: 53% is used in semiconductors and high-end electronic solder, 16% in fine tin chemical new materials, 11% in food-grade tinplate and tin cans, and 8% directly in the PV green new energy industry. Tin Applications in High-Growth Sectors Currently, three major high-growth tracks worldwide are continuously driving rigid incremental demand for tin. First, AI computing power and hyperscale data centers: The tin consumption per unit of high-end AI servers is 3–13 times that of ordinary servers. With the explosive growth of global AI computing power demand, the demand for high-end solder will continue to grow rapidly. Second, new energy vehicles: Tin consumption per vehicle is about three times that of internal combustion engine vehicles, and for intelligent car models, it can reach up to 1.5 kg per vehicle. Third, advanced packaging: The solder ball usage of advanced packaging technologies such as HBM (High Bandwidth Memory) is more than five times that of traditional DRAM. Malaysia at a Crossroads The Decline of a Former Empire and Opportunities for Transformation ► Glorious History · Tin Empire: In the 1960s, Malaysia was the world's veritable "Tin Empire." Its tin production once accounted for one-third of the global total, and revenue from tin exports represented as much as 60% of the country's total export revenue, dominating the global tin trade landscape. ► Current Situation · Dual Challenges: However, after industrial iteration, its share of global production was only 0.2% in 2023, with annual output falling to 6,100 mt, marking a sharp decline. Malaysia still holds considerable secondary resource reserves of 780,000 tonnes, with native ore depleted but tailings holding significant potential. ► Future · Reshaping Value Strategic Empowerment: Leverage the new strategic identity of “critical minerals” to enhance discourse power and bargaining power in the international supply chain. Industrial Leap: Shift away from dependence on primary tin ingot exports and move towards high value-added deep processing manufacturing and the establishment of a circular economy system. Core Challenges Faced Currently, Malaysia’s tin industry faces four core structural challenges. Market Breakthrough: Reshaping Value Embrace the New Identity and Extend into Downstream High Value-Added Sectors Build a Regional Circular Economy Center Core Strategy: Fully leverage Malaysia’s industrial advantage as a global electronics manufacturing center, turning the large amount of tin-containing scrap generated during production—including solder dross, waste circuit boards, etc.—into valuable recycled tin resources, and establish an “urban mining” resource recycling system.

Market Data as of 15:07 Today Macro Front China: [NEA: Total Electricity Consumption Reached 2,514.1 billion kWh, Up 5.2% YoY, January-March] The National Energy Administration released March electricity consumption data. From January to March, total electricity consumption reached 2,514.1 billion kWh, up 5.2% YoY. By sector, the primary industry consumed 33.6 billion kWh, up 7.1% YoY. The secondary industry consumed 1,598.7 billion kWh, up 4.7% YoY; of which, industrial electricity consumption was 1,583.6 billion kWh, up 4.9% YoY, and high-tech and equipment manufacturing consumed 274.6 billion kWh, up 8.6% YoY. The tertiary industry consumed 483.3 billion kWh, up 8.1% YoY; of which, EV charging and battery swapping services and internet data services consumed 37.6 billion and 22.9 billion kWh respectively, with growth rates of 53.8% and 44.0%. Urban and rural residential electricity consumption was 398.5 billion kWh, up 3.4% YoY. [April LPR Unchanged: Both 5-Year and 1-Year Rates Held Steady for the Eleventh Consecutive Month] The April LPR was announced: PBOC kept the 1-year and 5-year LPR at 3% and 3.5% respectively, unchanged for the eleventh consecutive month. [Foshan's Commercial Housing "Trade-in" Policy Is Here! First Batch Involves 22 Residential Projects] Recently, the Notice on Organizing the First Batch of Commercial Housing "Trade-in" Program by the Foshan Municipal Housing and Urban-Rural Development Bureau was officially released. This is not merely an encouraging document; it is a solution that systematically clears bottlenecks in housing replacement through model innovation and a policy package. It aims to drive the real estate market's transition from "one-sided transactions" to a "virtuous cycle between existing and new housing stock," achieving a win-win outcome for residents, enterprises, and the market. The innovation of Foshan's trade-in policy lies in bringing multiple real estate enterprises into the program: Foshan Anju, Chancheng Anju, Nanhai Youju, Shunde Chengtie, Gaoming Airport Construction, and Sanshui Anju serve as acquisition entities, while Foshan Chengfa, Foshan Urban Renewal, Foshan Lianzhi, Heyue Yaji, Shunkong Chengtou, Yongdeli Commerce, Sanshui Chanfa, and Miaohui Real Estate provide new housing sources. This model determines the value of existing homes through negotiation, establishes a "contract termination protection period" to avoid blindly pushing for lower prices, thereby completing the "sell old, buy new" closed loop and serving as a market stabilizer. (Foshan Release) US Dollar: As of 15:07, the US dollar index rose 0.03% to 98.26. According to a CITIC Securities research report, US Fed Governor Miran and three other economists recently co-published a working paper titled "A User's Guide to Restructuring the Federal Reserve's Balance Sheet," whose structure bears similarities to the previously widely discussed "A User's Guide to Restructuring the Global Trading System." The paper challenges the conventional view that the US Fed cannot significantly reduce its balance sheet, arguing that reserve demand is largely determined by the regulatory environment and that balance sheet reduction can be achieved without causing unexpected market stress by adjusting the regulatory framework, curbing precautionary motives, and addressing other sources of reserve demand. Using Monte Carlo simulations, the paper estimates the potential balance sheet reduction space at $1.2 trillion to $2.1 trillion. We believe the "balance sheet reduction guide" has a certain degree of real-world feasibility, but some options are somewhat idealistic. (Jin10 Data APP) According to the CME "Fed Watch": the probability of the US Fed raising interest rates by 25 basis points in April was 0.5%, while the probability of keeping rates unchanged was 99.5%. The probability of a cumulative interest rate cut of 25 basis points by June was 4.5%, the probability of keeping rates unchanged was 95%, and the probability of a cumulative rate hike of 25 basis points was 0.5%. (Jin10 Data APP) On the macro front: Germany's March PPI month-on-month rate, Canada's March CPI month-on-month rate, and other data were to be released today. Also worth noting: German Chancellor Merz and European Central Bank President Lagarde delivered speeches; Trump said a US delegation would arrive in Islamabad on the evening of the 20th for negotiations, while Iran denied reports of a second round of talks being held in Islamabad. Crude oil: As of 15:07, oil prices in both markets surged, with WTI up 6.42% and Brent up 5.9%. Iran had once again closed the Strait of Hormuz, driving oil prices sharply higher. On the 19th local time, an Iraqi oil ministry official said the closure of the Strait of Hormuz would block the export of nearly 4 million barrels of Iraqi crude oil over the next three days. The Iranian Islamic Revolutionary Guard Corps Navy issued a statement on the 18th saying that, due to the US violating ceasefire commitments and failing to lift the naval blockade on Iranian ports and vessels, the Strait of Hormuz would be blocked starting that evening. (CCTV News) Gary Pedersen, head of trading house Gunvor, warned that the oil market was facing more turbulence as Middle East tensions collided with seasonal slowdown in crude oil demand, increasing the likelihood of further sharp and unpredictable fluctuations in crude oil prices. (Jin10 Data) The International Energy Agency forecast that global crude oil demand would decline by 1.5 million barrels per day in Q2, the largest drop since the COVID-19 pandemic. OPEC's forecast was relatively mild, projecting a daily decline of 500,000 barrels. (Jin10 Data) A CICC research report noted that as the Iran situation entered its 7th week, the situation saw a further turning point. Although the first round of peace talks "collapsed," both the US and Iran "announced" the reopening of navigation through the Strait of Hormuz, which still largely boosted optimistic sentiment in the market, despite subsequent reversals. This was largely in line with our base case assumption: while short-term reversals remain possible, a complete loss of control over the medium term is not the base case scenario, as Trump still has midterm elections to consider, and a comprehensive and uncontrollable escalation serves neither side's interests. Under this scenario, the Brent crude oil price center would gradually pull back to around $80 in Q2 and Q3, and the US Fed could still cut interest rates.

[SMM Morning Meeting Summary: Macro Factors and Fundamentals Resonated, and LME Zinc Logged a Three-Day Winning Streak] Overnight, LME zinc logged a three-day winning streak, with support from the 20-day moving average below and resistance from the 40/60-day moving averages above. Overnight, as geopolitical tensions in the Middle East may have de-escalated, the US dollar index moved lower, nonferrous metals rose, and LME zinc inventory continued destocking......

Saudi Finance Minister, Mohammed Al-Jadaan, has cautioned that recent global supply chain disruptions are now exceeding the impact seen after the COVID-19 pandemic. He noted that ongoing geopolitical tensions could have wider economic consequences if they continue for an extended period of time. He pointed out that while oil markets often draw the most attention, the pressure is becoming more visible across key industrial sectors such as refined products, fertilisers, steel, aluminium and petrochemicals.

“Gold’s status as a haven may now be tarnished in the eyes of some as the precious metal is falling in price even as war roils the Middle East and financial markets alike, and some may even be tempted to say that the third major bull run in the commodity since 1971 is now over,” says AJ Bell investment director Russ Mould.

Silver's performance over the past year has been nothing short of spectacular.

On Tuesday this week, the latest survey of fund managers released by Bank of America once again revealed a fact that most people already knew: nearly everyone on Wall Street is currently shorting the US dollar.

At the 2025 SMM (2nd) Global Renewable Metal Industry Chain Summit - Main Forum hosted by SMM Information & Technology Co., Ltd., Allen Cui, Director of SMM Nonferrous Consulting, shared insights on the topic of "Prospects for the Development of the Global Secondary Metal Industry."
