“Tin” Leads the Future: Industry Transformation and Value Reshaping in the New Cycle Conference Background At present, the global tin industry is standing at a historic turning point. The traditional cycle logic has been completely disrupted, and its strategic value has become fully evident. In 2026, the tin market presented an unprecedentedly complex landscape and profound changes: I. The supply-demand pattern is being deeply reshaped, and strategic attributes are rising to an unprecedented level The global tin resource static reserve-to-production ratio was only 14 years, with scarcity becoming increasingly prominent. The supply side faced “triple pressures”: repeated twists and turns in Myanmar’s production resumptions, continued tightening of Indonesia’s policies, and elevated geopolitical risks in the DRC. Resource constraints had become the new normal. Meanwhile, the demand structure underwent a fundamental shift, and tin has become a strategic resource connecting traditional manufacturing with the digital future. II. The pricing system breaks through history, and the industry ecosystem faces reshaping In early 2026, SHFE tin prices broke through 470,000 yuan/mt, setting a record high. This price breakthrough was not only a reflection of the supply-demand imbalance, but also a sign of value reassessment in the tin industry. Traditional trading models, risk management systems, and supply chain collaboration approaches were all in urgent need of innovative breakthroughs. III. Technology-driven and green transformation give rise to a new symbiotic ecosystem Digital and intelligent technologies were deeply empowering the tin industry chain. Global green transformation required the tin industry to upgrade toward low-carbonisation and a circular economy, making recycled tin recovery and green smelting processes an inevitable path. Every link of the industry chain must shift from competition to collaboration, building an open, resilient, and innovative symbiotic system. Against this backdrop, August 19-21, 2026 in Changsha, Hunan the 2026 SMM (16th) Tin Industry Chain Conference will bring together global industry elites for joint discussions.

[7.22 Morning Briefing] The CSRC held an investor symposium to hear opinions and suggestions. Investor representatives suggested adopting multiple measures to guide medium and long-term funds into the market, and regulating the development of quantitative trading and AI applications. The most-traded SHFE nickel 2609 contract fluctuated higher in the morning session, and as of the morning close it was quoted at 130,370 yuan/mt, up 0.09%. As the conflict between the US and Iran escalates, shipping in the Strait of Hormuz has been restricted, and sulfur cost support has strengthened somewhat. However, refined nickel inventory remains difficult to reduce, with domestic and international inventories still at high levels and a slow destocking speed. In the short term, the price of the most-traded SHFE nickel contract is expected to trade in the range of 125,000–130,000 yuan/mt.

[SMM Tin Morning Briefing: Korean Giants Frequently Signal Expansion, SHFE Tin Night Session Rises Over 1% to Return to 410,000]

SMM, July 21: US Secretary of State Rubio stated in a media interview on the evening of the 19th that the Trump administration “remains open to a diplomatic solution.” Expectations of a negotiated settlement between the two sides in the market tug-of-war heated up, and international oil prices pulled back in tandem. Earlier inflation concerns driven by energy prices cooled, and the market’s bets on the US Fed holding high interest rates weakened marginally. Coupled with a sharp rebound in Asia-Pacific stock markets today, overall market risk appetite improved. The built-up sentiment for an oversold rebound in precious metals was released in a concentrated manner, and multiple positive factors resonated to drive a rebound in both precious metals futures and equity prices. Zhaojin Gold, Shandong Humon Smelting, Western Gold, and other precious metals enterprises reported positive H1 earnings forecasts, and the favour from some market funds also contributed to the synchronized strength in precious metals futures and stocks. As of around 13:35 on July 21, COMEX gold was up 1.07% at $4,058.7/oz; SHFE gold main contract rose 1.31% to 885.6 yuan/g; COMEX silver gained 2.13% to $58.285/oz; SHFE silver main contract advanced 3.65% to 14,186 yuan/kg; silver T+D increased 2.84% to 14,113 yuan/kg. Additionally, platinum main contract rose 1.63% to 399.3 yuan/g, and palladium main contract gained 2.87% to 302.4 yuan/g. Precious metals stocks surged. As of the close on July 21, the precious metals sector rose 7.34%. Among individual stocks: Xingye Silver&Tin, Chifeng Gold, and Shengda Resources hit the daily limit up; Xiaocheng Technology, Shanjin International, Hunan Silver, Zhongjin Gold, and Shandong Gold were among the top gainers. News [Russia’s gold holdings fell to 73.4 million ounces in June] The Russian central bank stated on its website that as of month-end June, the value of its reserves was $299 billion, compared with $325.9 billion at the end of May. [World Gold Council: Chinese market gold ETFs saw significant inflows in H1] According to the World Gold Council, gold prices weakened in June, erasing earlier gains, and H1 ended with a decline. Despite outflows in June, Chinese market gold ETFs still recorded significant inflows in H1, driving total assets under management slightly up to 243 billion yuan, with total holdings increasing by 29 mt to 277 mt. [Zhaojin Gold: expects H1 2026 net profit to increase 347.48%-436.98% YoY] Zhaojin Gold disclosed its earnings forecast on the evening of July 14. It expects H1 2026 net profit attributable to parent at 200 million to 240 million yuan, up 347.48%-436.98% YoY; and non-recurring net profit of 80 million to 116 million yuan, up 490.44%-756.14% YoY. [Shandong Humon Smelting: Estimated H1 2026 Net Profit Up 81.06%-122.36% YoY] Shandong Humon Smelting disclosed its earnings forecast on the evening of July 14, estimating H1 2026 net profit attributable to shareholders at 570 million – 700 million yuan, up 81.06%–122.36% YoY; adjusted net profit is estimated at 272 million – 402 million yuan, down 2.03%–33.73% YoY.

[Zhongjin Gold: Estimated H1 2026 Net Profit of 4.1 Billion – 4.6 Billion Yuan, Up 52.15%-70.7% YoY] Zhongjin Gold disclosed its earnings forecast on the evening of July 13, estimating H1 2026 net profit attributable to shareholders at 4.1 billion – 4.6 billion yuan, up 52.15%–70.7% YoY; adjusted net profit is estimated at 4.05 billion – 4.55 billion yuan, up 36.96%–53.87% YoY. Spot Market Silver On July 21, the SMM 1# silver ex-factory reference average price in the morning was 13,825 yuan/kg, with the average up 0.7% from the previous trading day. In the spot market, premium/discount quotes that day extended the trend of previous days, with consumption remaining sluggish and transactions being mostly at parity to slight discounts. The spot-futures price spread on the futures market widened slightly, and some suppliers reduced shipments. Early morning quotes in the Shanghai area were mainly concentrated at TD parity to +5 yuan/kg, with some rigid demand orders supporting transactions and suppliers’ willingness to sell weakening. In the Shenzhen area, some national-standard cargoes were concentrated around TD -5 yuan/kg to parity, with low-priced cargoes existing but having limited disruption. That day, the market’s premium/discount against the SHFE2608 contract was at a discount of 20 – 30 yuan/kg; against the most-traded SHFE contract 2610, it was at a discount of 40 – 60 yuan/kg. Overall, precious metals lacked clear guidance from news, and recently both domestic and overseas futures markets have shown signs of bulls entering, so attention can be paid to changes in open interest. Spot premiums/discounts traded near parity, and the pattern of weak supply and demand persisted. Platinum On July 21, spot platinum was quoted at 395 – 398 yuan/g, with the average price at 396.5 yuan/g, unchanged from the previous trading day. Spot market, mainstream quotations for platinum were at parity to a premium of 1 yuan/g against the PT2608 contract. The premiums/discounts of mainstream quotations were basically flat from the previous trading day. Today, the price spread between the GFEX platinum October and August futures contracts widened slightly. In the morning, suppliers' quotes for spot platinum were mainly at premiums of 0.5 to 1 yuan/g against the most-traded GFEX contract. Later, as the futures market rose, some suppliers adjusted their quotes to around parity, where transactions were made. Downstream users made small purchases based on orders. Overall, the spot platinum market saw normal trading volumes today. In July, a Section 232 window for platinum and palladium will open. If the US imposes tariffs on platinum and palladium after the 180-day negotiation period ends, it will support prices in the short term. Voices from Various Sides Regarding the future trend of precious metals, some institutions' views are as follows: Jinyuan Futures research report stated: The recent escalating US-Iran tensions have pushed oil prices higher, lifting inflation expectations. Precious metals remained under pressure but their decline slowed. After the sharp pullback in gold and silver prices, bargain-hunting buying emerged. The correction in US tech stocks will also redirect some funds into precious metals. Although the correction trend in gold and silver is not yet over, the probability of a rebound is increasing. Hundun Futures research report noted: As geopolitical tensions continue to seesaw, the market is not yet convinced enough to expect an overall pullback in oil prices. Inflation expectations could rebound from lows, limiting the decline in US bond yields. Hence, the rebound in precious metals remains limited under these circumstances. The US Fed's relatively cautious remarks have also capped the rebound in precious metals. Fed Chairman Warsh said the balance sheet should be kept as small as possible so that it can expand in a crisis. The labour market looks quite good, but he is not optimistic about inflation and is dissatisfied with it; Fed's Williams stated that with inflation still elevated, it must be brought back sustainably to the 2% target, and the current monetary policy stance is very well positioned to achieve that; Logan said that a modest rate hike now would help better balance the outlook and risks, and moderate tightening now is better than having to tighten significantly later. The Fed's stance is clearly cautious, unwilling to let the market overprice a relaxation of vigilance. The market dares not further trade interest rate cut expectations, and precious metals weakened again. Liquidity and risk appetite remain weak under the influence of the equity market. As AI fundamentals are being reassessed, deleveraging in funding further amplifies volatility. The continued decline in the equity market has made liquidity relatively tight and restricted the drivers for precious metals. At this stage, the overall market is still dominated by sentiment-driven trading. Geopolitics, the AI narrative, and economic/inflation resilience mean the US dollar index and US bond yields will remain volatile. A trend reversal in precious metals still needs to be observed. Analysts at ANZ Research said in a report that physical gold demand and central bank purchases are supporting the gold market. These analysts added that while gold faces short-term headwinds from the US Fed’s tightening expectations and a strong US dollar, investment positions in gold look thin after months of exchange-traded fund outflows, suggesting that the scope for further declines may be limited. A high interest rate environment typically weighs on non-yielding assets such as gold. (Zhitong Finance) Goldman Sachs said that despite pressure from the US Fed’s tightening-leaning expectations, central bank buying is expected to provide a floor for gold. Demand remains robust, with central banks purchasing 81 mt in May and a three-month average of 67 mt per month, well above the pre-2022 average of 17 mt, according to the firm’s estimates. Goldman Sachs analysts stated, “We believe the trend of central banks increasing gold holdings will persist for years as they diversify reserves to hedge geopolitical and financial risks.” The bank expects average monthly purchases of 50 mt and 40 mt for this year and next year, respectively. (Jinshi Data APP) Soojin Kim, analyst at MUFG, said, “Recent price action suggests that the market is placing greater weight on the possibility of US interest rates staying high for longer rather than on gold’s traditional safe-haven demand. This leaves gold vulnerable to pressure unless geopolitical risks further translate into a broad deterioration in financial market sentiment.” (Jinshi Data APP) Asset manager Fidelity International said it plans to rebuild its gold position, which it reduced earlier this year, at an appropriate time in the future, believing that gold’s long-term momentum remains strong. Ian Samson, multi-asset portfolio manager at Fidelity International, recently said, “We plan to add back to gold, the question is just timing.” He said he reduced the gold allocation to a neutral level during the January-February period, when the multi-year bull run in gold abruptly ended. Samson expects the gold market to re-enter a bull market sometime in 2027. The logic of a return to a bull market would only be disrupted in a scenario where “governments re-embrace fiscal discipline and central banks truly commit to bringing inflation back down,” he added, “but I don’t think we are in that world right now.” Samson also said that continued gold purchases by central banks—a key driver of the previous bull market—will continue to support gold prices. Last Thursday, US Eastern Time, technical strategists at Bank of America warned that the pullback in gold so far this year may still have significant room to run, and its trajectory could resemble the devastating bear markets that followed the sharp rallies in gold in 1980 and 2011. They proposed a phased buying strategy, suggesting full allocation only when gold prices fall to the $3,450–$3,250 range. Bank of America analysts pointed out in a technical research report that gold prices have now accumulated a series of bearish signals, with the risk of a sustained drop increasing: a death cross pattern, elevated net long positions, a bearish topping candlestick, a TD Sequential exhaustion signal, and an RSI reading of 90 at the recent high—a level consistent with the gold price peaks in 1980 and 2011. UBP lowered its year-end gold price target to $4,800 per ounce and, while remaining long-term bullish on gold, is not adding to positions for now. Its current gold allocation is neutral at around 5%, down from an overweight position earlier this year. Paras Gupta, head of discretionary portfolio management for Asia at UBP, said in an interview that the previous overweight position "posed the greatest risk to our portfolios." UBP would like to see the Middle East ceasefire agreement hold and more clarity on inflation and interest rate trends before adding to its positions. Gupta said that for investors currently without gold holdings, a drop below $4,000 per ounce would be an extremely attractive entry point. (Zhitong Finance) Recommended reading:

[ SMM Stainless Steel Daily Review ] SS Futures Consolidate on a Strong Note; Stainless Steel Spot Prices Hold Steady, Shipment-Driven Trading Edges Up Slightly According to SMM on July 21, SS futures maintained a consolidation trend on a strong note overall. Aligning with the non-ferrous metals sector’s further surge, SS futures consolidated and strengthened simultaneously. The most-traded SS futures contract closed at 14,775 yuan/mt by the midday break. In the spot market, driven by the strength in SS futures, spot stainless steel quotations remained temporarily stable despite traders’ active selling pressure and weak demand during the traditional off-season, which led to low acceptance of high-priced cargoes downstream. Nevertheless, trading activity improved. SS Most-Traded Futures Contract. At 10:15 a.m., SS2609 was indicated at 14,740 yuan/mt, flat from the previous trading day. Spot premiums for 304/2B in the Wuxi area ranged from 230 to 630 yuan/mt. In the spot market, the average price for cold-rolled 201/2B coils in Wuxi remained flat; the average price for cold-rolled raw-edged 304/2B coils remained flat in Wuxi and flat in Foshan; cold-rolled 316L/2B coil prices in Wuxi remained flat; hot-rolled 316L/NO.1 coil quotations remained flat in Wuxi; cold-rolled 430/2B coil averages remained flat in both Wuxi and Foshan. This week, the macro backdrop featured easing US CPI data and cooling inflation expectations, while market risk appetite saw a modest recovery. Additionally, Indonesia’s Ministry of Energy and Mineral Resources (ESDM) clarified that nickel ore production quotas for the year would be supplemented only moderately and on a limited scale, implying constrained incremental growth and a continuation of the raw material supply shortage. These factors provided a solid floor for the spot market, spurred a rebound in SHFE nickel and SS futures. On the spot and inventory front, prices were held firm by steel mills, while shipments…

H1 silver concentrate imports surged 35.5% YoY, while refined silver exports stayed flat. Q2 saw heavy stockpiling in Shenzhen, disrupting spot pricing. Since late June, low-price inventories have cleared and投机盘 have retreated, stabilizing quotes. However, risks from remaining low-cost stocks remain.

Against the backdrop of accelerated global advancement in the circular economy, the recycling industry is expanding from mere resource recycling to diversified value. As a renowned information service platform for China’s non-ferrous metals sector, Shanghai Metals Market (SMM) has long focused on the recycling segment, building a comprehensive service ecosystem for renewable resource recycling that encompasses data, news, price benchmarks, industry conferences and supply-demand matchmaking. The annual Battery Recycling and Circular Industry Conference (GBRC) organized by SMM has grown into one of China’s largest and most influential industry events in the renewable resources sector. Meanwhile in Brazil, across the ocean, a non-profit organization is interpreting the social value of recycling in an alternative way: repurposing scrap materials into tools for robotics education to open the door to the digital world for children in public schools. Founded in 2016, Sementes do Vale is a non-profit organization dedicated to sports, culture, education, technology, vocational training and social psychological support. Its flagship initiative, the e-Ducar (Educational Robotics with Scrap Materials) , centers on the dual pillars of "recycling plus education" and reduces educational inequality by democratizing access to digital education for students and public schools through educational robotics, computational thinking for understanding Artificial Intelligence, and STEAM methodology. To date, the programme has served 38 public schools across 7 cities in 2 Brazilian states, trained 164 teachers, and directly benefited 4,331 students. More importantly, it is not a one-off workshop, but rather a path designed so robotics enters the school and stays there, even after we leave. How It Works Four Steps, One Complete Ecosystem E-Ducar project 's core competitiveness lies in its design of a fully integrated implementation pathway that covers everything from teacher training to teaching materials, from hardware to curriculum standards, ensuring that schools can independently conduct robotics courses even after the project withdraws. Step-1: Teacher Training The heart of the project. Free in-person training for public-school educators: robotics fundamentals, block-based programming, computational thinking, and how to integrate everything into the school curriculum. Step-2: Materials and Video Lessons Each teacher leaves with a complete pedagogical kit: ready-to-use lesson plans, an e-book, hands-on activities with scrap materials, and video lessons on YouTube. Everything is open, free, and permanently available. Step-3: Free robotics kits Each partner school or education department receives robotics kits to use in classes with its students. Step-4: Aligned with Brazil's national curriculum Digital education became mandatory by law in Brazilian schools, and the project materials were structured to support this adaptation through educational robotics, computational thinking, and STEAM methodology. Robotics Is a Right, Not a Privilege for the Few Robotics is a right, but it reaches very few. Even with Law No. 14,533/2023 guaranteeing the right to digital education, most Brazilian public schools have never offered a robotics class. e-Ducar was born to change that statistic, one classroom at a time. From the perspective of the recycling industry, this also represents a deep extension of circular economy principles into society: at the industrial end, scrap metals and waste electronic components re-enter the industry chain through regenerated smelting, while in the education sector, they can similarly be creatively reassembled into tools for inspiring the next generation’s interest in technology. Just as SMM has long advocated the concept of "full life cycle resource circulation," the value of recycling is reflected not only in metal recovery rates and economic benefits but also in the long-term value of sustainable development. Support the Project If you are an educator, school leader, education department, or company that wants to support us, let's talk. Robotics from the Sertão can be where you are. Building Communication Platform Between China and the World: SMM Supports Global Circular Science Education Public Welfare As a professional information service platform serving the global renewable resources and battery recycling sectors, SMM has long dedicated itself to research on recycled metals and lithium battery recycling as well as building platforms for industrial supply and demand exchange. Beyond these core businesses, SMM has consistently incorporated sustainable public welfare initiatives into its long-term corporate social responsibility strategy. SMM will continue to monitor non-profit organizations worldwide that deliver inclusive science and technology education using recycled materials. The e-Ducar programme stands out as an exemplary social innovation that SMM supports. Backing non-profit organizations such as Sementes do Vale to advance the e-Ducar initiative not only fosters inclusive education and mitigates educational inequality across Latin America, but also serves as an effective channel for the industry to popularize circular economy knowledge and disseminate sustainable development concepts. Moving forward, SMM will keep building communication platforms between industrial players from China and overseas non-profit organizations, encouraging more recycling enterprises to participate in cross-border science and education support programmes. By leveraging industrial expertise to empower equitable sustainable education globally, SMM will fully implement integrated ESG practices that deliver environmental benefits, social value and long-term development.

[7.21 Morning Briefing] US media reports: US-Iran conflict intensifies, the Pentagon is accelerating the deployment of F-16 and F-35 fighter jets to the Middle East. Advisor to Iran’s Supreme Leader: If US forces continue operations, Iran may shift to a full-scale offensive. The most-traded SHFE nickel 2609 contract surged in early trading then pulled back slightly, and as of the morning close, it reported 130,720 yuan/mt, down 0.13%. As the US-Iran conflict escalates, shipping restrictions in the Strait of Hormuz have strengthened sulfur cost support. However, refined nickel inventories remain difficult to reduce. Both domestic and international inventories are still at high levels, and the destocking speed is slow. In the short term, the price of the most-traded SHFE nickel contract is expected to trade within the range of 125,000-130,000 yuan/mt.

SMM News, July 20: To deepen industry exchanges, facilitate information channels, and jointly explore development trends and market dynamics in the lead and zinc industry, on July 20, Geng Zhiyao, Senior Analyst for Copper, Lead and Zinc at SMM Information & Technology Co., Ltd.
