SMM May 28 update: The minor metal sector strengthened on May 28. As of the close on May 28, the minor metal sector rose 3.44%. In terms of individual stocks: Sino-Platinum Metals, Yunnan Germanium Industry, and China Molybdenum hit the daily limit, while China Minmetals Rare Earth, China Tungsten And Hightech, China Northern Rare Earth, and China Rare Earth led the gains. On the news front: According to authoritative local media in Zimbabwe and Xinhua News Agency, the Zimbabwean government recently issued the Mineral Classification and Declaration, explicitly listing lithium and other high-value minerals as "critical minerals" subject to equity and export controls. The critical minerals involved include 14 types: lithium, nickel, cobalt, graphite, copper, rare earth elements, chromium, platinum group metals (PGMs), manganese, antimony, uranium, ruthenium, tungsten, and niobium. The market is focused on the impact of tightening resource-country policies on global supply chains, with sentiment warming for minor metal varieties such as antimony and tungsten. Spot market Tungsten According to SMM pricing, on May 28, the average price of wolframite concentrates (≥65%) was 415,500 yuan/standard tonne (65%WO3 basis), up 1.22% from the previous trading day. Notably, after wolframite concentrates previously experienced a 61.88% decline over more than two months, driven by increased purchasing demand in the tungsten market, tungsten prices saw a rebound over two trading days. Currently, transactions in the tungsten concentrates market have improved, suppliers are bullish and hold back from selling, high-grade ore sees an upward shift in transaction center, while medium and low-grade ore circulates more but price increases appear lackluster. Downstream APT industry operating rates have slightly improved, but with limited new orders in the industry, smelters are cautious in restocking, with only small volumes of spot orders and large orders transacted in the market. Regarding the tungsten outlook, in the short term, driven by orderly inventory destocking, the return of downstream rigid demand, and the formation of pricing consensus among industry leaders, the tungsten market has overall entered a consolidation-at-lows and recovery phase. Going forward, key attention should be paid to the execution of long-term contracts and the pace of end-use demand recovery. According to SMM surveys, downstream cemented carbide alloy enterprises have seen inventory drop to low levels, with expectations of rigid restocking demand, but influenced by the market not yet being fully stabilized, enterprises remain cautious in procurement, generally adopting a small-order purchasing model. If upstream raw material inventory continues to be cleared and supply-demand imbalances are alleviated, tungsten prices are expected to enter a stabilization and consolidation phase in June-July. In the medium and long-term, the gap in Q3 mining quota transitions may lead to a contraction in market supply, coupled with expectations of the traditional September-October peak season, the industrial supply-demand structure will continue to optimize, thereby providing bullish support for tungsten prices. Rare Earths After the rally on May 27, the average price of Pr-Nd oxide on May 28 fell 1.79% from the previous trading day, and inquiries in the rare earth oxide market were sluggish on the 28th. Affected by futures price fluctuations combined with periodic restocking by some major producers, Pr-Nd oxide prices fluctuated frequently this week. Upstream and downstream players continued their stalemate, with suppliers maintaining relatively firm offers overall, while downstream metal producers maintained a strong wait-and-see sentiment and showed low purchase willingness at high prices. Absent other news-driven factors, Pr-Nd oxide is expected to remain in the doldrums in the short term before any significant change in the supply-demand relationship. Institutional Views Huafu Securities noted in its research report dated May 24, when commenting on other minor metals: rare earths performed weakly, while tantalum pentoxide surged during the week. In the rare earth market, end-use demand from downstream magnetic material sectors remained weak, with no large-scale concentrated restocking observed — only sporadic rigid-demand small orders were transacted, and the demand side consistently failed to provide effective support for the market. Market sentiment fluctuated significantly, with frequent tug-of-war between longs and shorts. Overall industry confidence was insufficient, with a notable stalemate between upstream and downstream on offer and bid prices, and significant divergence within the industry regarding the outlook for subsequent market trends. On Friday, the market maintained a wait-and-see attitude, awaiting changes in the magnetic material restocking pace and a recovery in downstream demand. Individual stocks: for antimony, Hunan Gold, Huaxi Nonferrous, and Huayu Mining are recommended; for molybdenum, China Moly, China Gold, and CMOC; for tungsten, Jiaxin International Resources, China Tungsten High-Tech, Xiamen Tungsten, and Zhangyuan Tungsten; for rare earths, China Rare Earth, China Northern Rare Earth, JL MAG Rare-Earth, and Xiamen Tungsten. Kaiyuan Securities' mid-year 2026 investment strategy for the metals sector indicated: Copper: Supply side, most ex-China miners continued to face declining ore grades and recovery rates, with disruption factors persisting (Ivanhoe's Kamoa-Kakula copper mine, Codelco's El Teniente copper mine). Although China's domestic enterprises added incremental capacity, the overall increase was limited. Under optimistic assumptions, global supply growth from 2026 to 2027 may fall below 2%. Demand side, power demand in both China and the U.S. maintained high growth rates in H1, which is expected to contribute marginal incremental copper demand. Kaiyuan Securities believes that the supply-demand structural imbalance for copper will become more pronounced in 2026, supporting a rise in the copper price center. Lithium: Supply side, capital expenditure in the lithium industry contracted and supply discipline gradually took shape. Combined with frequent disruptions, supply elasticity in the lithium industry has declined notably compared to before. Meanwhile, energy storage demand sustained high prosperity, driving gradual improvement in the lithium demand structure and marginal easing of inventory pressure. Lithium prices are expected to see a phased recovery. Lithium enterprises with resource security, low-cost advantages, and integrated layouts are expected to see earnings recovery elasticity outperforming the industry average. Lithium mine and lithium chemicals companies with high resource self-sufficiency rates and strong cost control capabilities are worth watching. Tungsten: As a strategic metal where China holds a dominant position, tungsten ore supply is constrained by resource depletion, environmental protection, and other factors. Combined with the government's total volume control on tungsten ore mining, tungsten ore production release remains limited. Demand side, emerging sectors are boosting tungsten demand, which is expected to provide long-term support for tungsten prices. According to a CITIC Securities research report, the current metals sector valuation remains at a reasonable level, with aluminum, copper, nickel-cobalt-tin-antimony, and gold valuations at relatively low levels, and a valuation rebound is still anticipated. Sector dividends have pulled back slightly, but the projected dividend yields of some individual stocks still exceed 5%. Looking ahead to 2026, liquidity shocks are expected to ease, supply disruptions are expected to occur frequently, and certain downstream sectors are expected to sustain relatively high prosperity. It is recommended to maintain a focus on allocation opportunities in lithium, copper, rare earths, strategic metals, aluminum, and gold sectors. Recommended Reading:

The minutes of Xingye Silver&Tin's investor briefing announced on May 27 show: 1. Question: Mr. Sun! After the commissioning of Yinman Phase II, the plan is to mainly process lead-zinc-silver series ore, and the ore type and grade are expected to show relatively small changes compared to the Phase I lead-zinc system. Simply put, Zone 1 and Zone 4 are important resource replacement areas for Yinman Mining in the future, but currently they still belong to "potential zones" and cannot be directly classified into the "core rich ore" category like Orebody No. 17. Xingye Silver&Tin's response: Thank you for your attention! As of now, Orebody No. 17 is the main orebody that has been proven at Yinman. 2. Question: Hello, could you share the company's outlook on its own resources going forward and its assessment of the future market? Xingye Silver&Tin's response: Thank you for your attention! As an important participant in China's mineral resources sector and one of the world's leading silver-tin polymetallic mining enterprises, the company is firmly optimistic about its strategic layout, resource reserves, and industry prospects. 3. Question: Mr. Sun, over the past two years, the company has continuously pursued project acquisitions with an expanding financing scale. Can talent and technology be guaranteed? Can timely operations and safety be ensured? Xingye Silver&Tin's response: Thank you for your attention! In recent years, the company has prudently conducted project acquisitions and financing activities centered on its core business, with the overall expansion pace being controllable. Currently, the company has a complete talent pipeline and mature core technologies, and has established a standardized operational management and safety and environmental protection-related controls system, which can fully ensure the stable operation of all acquired projects and effectively prevent various risks. 4. Question: Mr. Sun, was your increase in shareholding in 2026 because you are optimistic about the company's several major projects this year? Xingye Silver&Tin's response: Thank you for your attention! Like other small and medium investors of the company, I am firmly optimistic about the company's potential investment value and plan to hold for the long term. 5. Question: @Director, Vice President and Board Secretary Sun Kai. Dear Secretary Sun, the company's Hong Kong IPO prospectus disclosed a 2026 tin production guidance of 5,500 mt, but Q1 production was only 777 mt, annualized at only 3,100 mt, far below the full-year guidance. May I ask: 1) Was the low Q1 production due to the technological transformation ramp-up of Yinman's copper-tin system, equipment commissioning, or low recovery rates? 2) What is the capacity release pace in subsequent quarters, and can the full-year guidance of 5,500 mt be achieved? 3) What are the timetable for reaching full production after technological transformation and the recovery rate improvement targets? Xingye Silver&Tin's response: Thank you for your attention! Based on the principles of comprehensive resource recovery and safe and efficient mining, the company simultaneously mines Orebody No. 17 and other copper-tin orebodies. For the company's production data, please refer to the periodic reports published on the company's designated information disclosure media. 6. Question: After the acquisition of Weiling Co., the company's related resources will inevitably be tilted toward that company. Please terminate the acquisition of Weiling Co. Xingye Silver&Tin's response: Thank you for your attention! Regarding the progress of the Weiling Co. project, please follow the relevant announcements disclosed by the company on designated media. 7. Question: What are the respective positioning of Xingye Silver&Tin A-shares, Xingye Silver&Tin H-shares, and Weiling Co.? Xingye Silver&Tin's response: Thank you for your attention! Regarding the progress of the Weiling Co. project, please follow the relevant announcements disclosed by the company on designated media. 8. Question: Dear Board Secretary, is the Q1 performance sustainable? What are the current capacity and inventory of silver and tin respectively? Xingye Silver&Tin's response: Thank you for your attention! In Q1 2026, the company's mined silver production was 78.95 mt and mined tin production was 777.33 mt. As of the end of Q1 2026, silver inventory was 15.04 mt and tin inventory was 83.67 mt. 9. Question: Is there a preliminary timetable for the Hong Kong listing? Can it be completed before the end of December this year? Among the company's plans, no projects have been implemented in Xinjiang yet. What kind of resources is the company planning for in the Xinjiang segment? Xingye Silver&Tin's response: Thank you for your attention! The company will release progress announcements on designated media in a timely manner based on project developments. Please stay tuned! 10. Question: Dear Board Secretary, how does the company view the sustained growth in silver and tin demand driven by AI and new energy? Tin production was 8,900 mt in 2024, but the 2026 guidance was lowered to 5,500 mt. What is the core reason? What is the pace of subsequent capacity release for the Yinman technological transformation and the Morocco project? Xingye Silver&Tin's response: Thank you for your attention! The materials related to the Hong Kong listing adopt the JORC Code, a technical standard developed by Australia. For example, the JORC Code defines "ore reserves" as the economically mineable part of measured and/or indicated mineral resources. The above standard differs to some extent from China's standards, resulting in certain deviations between the relevant data under planning and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 11. Question: Has the land certificate and construction permit for Yinman Phase II been obtained? Please do not respond with "please follow the relevant announcements disclosed by the company on designated media." Xingye Silver&Tin's response: Thank you for your attention! Yinman Phase II is expected to commence construction on July 1. After construction begins, the company will promptly disclose relevant progress announcements. Please stay tuned! 12. Question: Last year, the company was bullish on silver prices continuing to rise and chose to stockpile. Now silver prices are under pressure and the company did not hedge. Is the company still bullish on silver?The stock price has been continuously under pressure. Will the company proactively manage this? Xingye Silver&Tin replied: Thank you for your attention! As of now, the company has not conducted any futures hedging business. The company's hedging is carried out prudently at appropriate times based on actual production and operations as well as market conditions, with strict control over transaction risks. 13. Question: What is the current tin recovery rate at Yinman? The report for the Hong Kong listing shows a significant decline in grade. Is this in line with the company's current situation? If based on that report, it seems the company does not need to proceed with the Phase II expansion of Yinman, which appears somewhat contradictory. When will all of the company's capacity reach full production? After all capacity reaches full production, what will be the approximate production of silver and tin? Atlantic Tin has a gold exploration right. Could you briefly introduce the situation of that mine? Does the company have any plans to increase its equity stake in Far East Gold in the future? Xingye Silver&Tin replied: Thank you for your attention! The technical standards used in the Hong Kong listing materials are based on the JORC Code formulated by Australia. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term planning and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 14. Question: Hello, Secretary of the Board. The resource volumes and capacity plans for Yinman and Yubang Mining disclosed in the Hong Kong IPO prospectus are lower than the company's previous communication figures. What is the core reason? Is it due to differences in the JORC Code methodology (only including Measured and Indicated Resources, excluding Inferred Resources)? Does it involve resource reductions, grade downgrades, or mining plan adjustments? Is there room for future resource additions or upward revisions? Xingye Silver&Tin replied: Thank you for your attention! The technical standards used in the Hong Kong listing materials are based on the JORC Code formulated by Australia. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term planning and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 15. Question: Mr. Sun, based on the materials disclosed for the company's Hong Kong listing, the company's production of silver and especially tin is significantly lower than previous expectations. Is this estimate, this guidance, the company's true guidance, or a theoretical guidance made by SRK based on their assessment? Does the company plan to issue a medium and long-term guidance that is in line with the company's actual production plans to clarify these expectations?Otherwise, these expectations may have a significant negative impact on the company and noticeably undermine investor confidence. In fact, this is also unfavorable for the company's listing on international capital markets for financing and further development. Xingye Silver&Tin's response: Thank you for your attention! The Hong Kong listing-related materials adopt the JORC Code established by Australia as the technical standard. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term plan and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 16. Question: Mr. Sun, hello. The prospectus explains that there will be discrepancies between the Competent Person's planned mineral processing production schedule and the enterprise's actual situation. Could Mr. Sun please introduce the production plan for silver and tin from 2028 to 2030? Xingye Silver&Tin's response: Thank you for your attention! The Hong Kong listing-related materials adopt the JORC Code established by Australia as the technical standard. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term plan and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 17. Question: Specifically regarding Yinman Mining: according to SRK's data, there will be significant grade decline in the future. In addition, the feed grade differs considerably from the company's disclosures in the 2025 annual report and previous annual reports. Is it necessary to issue a specific announcement to provide an explanation based on the different mining standards? Xingye Silver&Tin's response: Thank you for your attention! The Hong Kong listing-related materials adopt the JORC Code established by Australia as the technical standard. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term plan and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 18. Question: Have the specific construction commencement dates been confirmed for Yinman Phase II, Yubang Phase II, the Morocco tin mine, and the Budun Yingen mine managed by the controlling shareholder? Could you also provide the commissioning and full production timelines? Thank you. Xingye Silver&Tin's response: Thank you for your attention! Yinman Phase II is expected to commence construction on July 1; the Yubang 8.25 million mt/year project is expected to commence construction in Q3; the Atlantic Tin project has obtained all construction permits and is currently carrying out preliminary preparation work including contractor tender and equipment transportation, with construction expected to commence in mid-July; all the above projects are expected to achieve commissioning with feed materials in Q4 2028. The managed company Budun Yingen plans to commence construction in Q4, with production expected to begin in 2029. 19. Question: Director Sun, in a previous institutional survey, you clearly stated that the company's quarterly tin production of 3,600 mt can be achieved on a regular basis. Is there an opportunity to achieve this quarterly target this year? Xingye Silver&Tin's response: Thank you for your attention! Adhering to the principles of comprehensive resource recovery and safe, efficient mining, the company simultaneously mines Orebody No. 17 and other copper-tin orebodies. For the company's production data, please refer to the periodic reports published by the company on designated information disclosure media. 20. Question: Does the company have the right to abandon the acquisition of the relevant equity in Weiling Shares? Xingye Silver&Tin's response: Thank you for your attention! For the progress of the Weiling Shares project, please refer to the relevant announcements disclosed by the company on designated media. 21. Question: Director Sun, in the records of a previous institutional survey, the company responded that Yinman's quarterly tin production of 3,600 mt can be achieved on a regular basis, but it seems this has not been realized subsequently. Is there a possibility of attempting to reach this record this year? Xingye Silver&Tin's response: Thank you for your attention!

The main reasons were: During the reporting period, the selling prices of the company's main mineral products such as silver and tin rose YoY; Yubang Mining's capacity was gradually released, with ore-derived silver production and sales increasing significantly YoY; and the transfer of 60% equity in Shuangyuan Non-ferrous realized investment income of 321 million yuan. Xingye Silver&Tin's 2025 annual report showed that in 2025, the company achieved operating revenue of 5.555 billion yuan, up 30.09% YoY; total profit of 2.096 billion yuan, up 18.75% YoY; and net profit attributable to shareholders of the publicly listed firm of 1.704 billion yuan, up 11.40% YoY. Xingye Silver&Tin's announcement showed that in 2025, the proportion of operating revenue from the company's main mineral products to total operating revenue was as follows: ore-derived silver (2.176 billion yuan, 39.17%), ore-derived tin (1.65 billion yuan, 29.70%), ore-derived zinc (975.87 million yuan, 17.57%), ore-derived lead (220.95 million yuan, 3.98%), ore-derived iron (180.38 million yuan, 3.25%), ore-derived copper (133 million yuan, 2.39%), ore-derived antimony (100.36 million yuan, 1.81%), ore-derived gold (82.34 million yuan, 1.48%), and ore-derived bismuth (16.67 million yuan, 0.30%). Among them, ore-derived tin and ore-derived silver combined accounted for 68.86% of total operating revenue. Regarding the company's main business and key performance drivers, Xingye Silver&Tin stated in its 2025 annual report: The company is a large mining group primarily engaged in the exploration, mining, and ore processing of non-ferrous metals and precious metals. As of the disclosure date of this report, the company had over 20 subsidiaries, of which 8 were operating mining companies, namely Yinman Mining, Qianjinda Mining, Yubang Mining, Rongguan Mining, Xilin Mining, Rongbang Mining, Ruineng Mining, and Bosheng Mining. Atlas Tin SAS under Atlantic Tin was in the construction phase for the Achmmach tin mine. Tanghe Times Mining was in a suspended construction phase, while Yitong Mining and Yunnan Xigui were in the exploration phase. Hainan Fund was primarily engaged in equity investment management; Xingye Gold (Hong Kong) was primarily engaged in metals and mining trading, corporate M&A, and was responsible for expanding markets outside China and acquiring quality mineral resources ex-China; Hainan Guomao and Tianjin Guomao were primarily engaged in non-ferrous metal mineral product sales and partial raw material procurement; Xingye Ruijin was primarily engaged in process research, technology R&D and upgrading in areas such as exploration, mining and processing, and comprehensive tailings recovery and utilization. Tibet Shannan Antimony Gold, Tibet Xinda Mining, and Xing'an League Fuxingtun Mining served as the company's regional resource integration platforms. During the reporting period, the company successfully acquired 85% equity in Yubang Mining. According to data compiled by the Silver Institute as of the end of 2023, Yubang Mining's monomer silver mine ranked first in Asia and fifth globally. This acquisition further strengthened the company's resource advantages and laid a solid resource foundation for sustainable development. Meanwhile, using its subsidiary Xingye Gold (Hong Kong) as the investment vehicle, the company increased investment in mineral resources outside China and successfully acquired 100% equity in Atlantic Tin. This acquisition was an important step in implementing the company's "going global" strategy. According to the classification standards for large-scale tin mines in the "Standards for Classification of Mineral Resource Reserve Scales" (DZ/T 0400-2022), the Achmmach tin mine owned by Atlantic Tin currently amounts to the equivalent of 5 large deposits. Through this integration of tin ore resources outside China, the company further improved its international tin ore layout and also reserved important strategic resources for long-term development. The company's main performance was derived from non-ferrous metal mining and processing operations. During the reporting period, revenue from non-ferrous metal mining and processing accounted for 99.64% of total operating revenue in 2025. Key factors affecting the operating performance of the mining and processing segment included production and sales volumes of major products, market prices, and costs of non-ferrous metal and precious metal mining and processing operations. Regarding the business plan, Xingye Silver&Tin stated in its 2025 annual report: 2026 is the concluding year of the company's "Second Three-Year" plan. The Board of Directors will closely focus on the theme of high-quality development, fully implement established work objectives, continue to deepen the philosophy of "Trust and Collaboration," and make an all-out push to achieve the closing targets of the "Second Three-Year" plan, with emphasis on the following areas of work: 1. Uphold the bottom line of safety and environmental protection. Using 2026 as the "Year of Safety Management Implementation," the company will comprehensively enforce safety responsibilities, consolidate the achievements of the "Year of Collective Safety Vigilance," strengthen risk anticipation and process control, resolutely prevent all types of safety and environmental protection incidents, and achieve safe, steady, green, and low-carbon development. 2. Advance key project construction at full speed, strengthen full-process management of project budgets, schedules, and quality, and coordinate the implementation of projects including the 2.97 million mt expansion of Yinman Mining, the 8.25 million mt expansion of Yubang Mining, the Morocco project, and the Budun Yingen Mining (under trusteeship) project, ensuring on-schedule completion, reaching full production, and releasing capacity benefits. 3. Continue to intensify exploration and reserve expansion efforts, properly balance production operations with geological exploration, steadily advance exploration of existing mines and surrounding areas, accelerate the conversion and upgrading of resource volumes, and continuously strengthen the resource foundation. 4. Deepen industrial synergy and resource integration. Leveraging the core regional advantages in Inner Mongolia, the company will steadily expand its resource layout outside China; adhering to silver and tin as the main business direction, it will enrich and optimize resource varieties. The company will solidly advance the subsequent acquisition and integration of Weiling shares, actively track quality mineral project opportunities in and outside China, and enhance overall competitiveness through synergistic industrial M&A. 5. Further strengthen institutional enforcement and internal control management, drive the effective implementation of various systems, processes, and control requirements, and enhance the company's refined management capabilities; strengthen enforcement capacity building to ensure production plans, comprehensive budgets, and various work deployments are fully implemented, and promote deep integration of corporate culture with business management. 6. Advance Hong Kong stock listing preparations at full speed, accelerate the establishment of a dual capital market platform at home and abroad, enhance cross-border capital operation capabilities, provide stronger financial support for the company's resource integration and strategy implementation, and drive the company's high-quality sustainable development to new heights. Reviewing the 2025 price performance of spot silver: the average price of SMM 1# silver (Ag99.99%) on December 31, 2025 was 18,430 yuan/kg, compared with 7,440 yuan/kg on December 31, 2024, representing an increase of 10,990 yuan/kg, or 147.71%. Recently, spot silver prices have been fluctuating. On May 27, the morning quote for SMM 1# silver (Ag99.99%) was 18,654–18,684 yuan/kg, with an average price of 18,669 yuan/kg, up 0.54% from the previous trading day. Compared with the average price of 18,430 yuan/kg on December 31, 2025, the price edged up by 239 yuan/kg, a gain of 1.3%. Regarding the outlook for precious metals, some institutions' views are as follows: FXTM Senior Research Analyst Lukman Otunuga stated: "As hopes for a US-Iran peace deal waver, gold prices have pulled back and are approaching the $4,450 support level. In addition, market expectations for a US Fed rate hike are steadily building amid conflict-driven price pressures, which is also exerting further downward pressure on gold prices." "Ultimately, if more signs emerge that price pressures are rising, it could further reinforce market bets that the US Fed will keep interest rates higher for longer, which would expose gold to greater downside risk." (Jin10 Data APP) CITIC Futures stated: Renewed tensions in US-Iran geopolitics have dampened risk appetite, while rising oil prices have reignited inflation concerns and strengthened market bets on a US Fed rate hike within the year, with multiple factors dragging silver prices lower. On one hand, US economic data still showed resilience, with the latest Chicago Fed National Activity Index for April at 0.14, significantly better than the previous reading of -0.15. The US May Conference Board Consumer Confidence Index and Present Situation Index both pulled back from prior readings, but the confidence index still beat market expectations. Combined with renewed US-Iran tensions pushing oil prices higher and sparking inflation concerns, market pricing for a year-end US Fed rate hike has strengthened. On the other hand, spot silver's fundamental drivers remained weak, with London market silver lease rates running at persistently low levels. In the short term, silver is expected to maintain a fluctuating trend, with overall capital interest still relatively low. Attention should be paid to US-Iran negotiation progress and strait navigation resumption. If US-Iran negotiations progress smoothly, this could drive a short-term silver rebound, but interest rate expectations will continue to suppress the trend. If geopolitical tensions escalate again and push oil prices higher, caution is warranted regarding further medium-term suppression of silver's industrial products elasticity and potential supply disruptions. Over the long term, weakening US dollar credibility, safe-haven demand, and investment demand provide solid support for silver prices. (Jin10 Data APP) A CITIC Securities research report noted that the resilience of the global economy is being tested by the Middle East conflict, with a glimmer of hope for the resumption of navigation through the Strait of Hormuz. The US economy may continue to grow mildly but unevenly this year, the pace of the EU's weak recovery is being delayed, and Japan's private-sector demand will inevitably be disrupted by energy shortages. High oil prices are already pushing up global inflation, with headline inflation rates in Europe and the US likely to fluctuate at highs this year, while Japan's headline inflation rate may continue its mild performance. The US Fed may not cut interest rates at all this year, while potential rate hikes by the ECB and BOJ are imminent, and the "unrestrained" fiscal stance of Japanese and European political circles may constitute a source of market risk this year. We maintain our view that US equities will outperform US bonds and that the US dollar index has support, and gold prices are expected to break free from their predicament as tail risks of inflation dissipate. ANZ analyst Kumar, Soni recently stated that inflation expectations, rising US Treasury yield, and a stronger US dollar are unfavourable factors putting gold prices under pressure. These factors will persist until we can clearly determine how long this conflict will last. Gold has fallen more than 14% since the outbreak of war in late February. OANDA Senior Market Analyst Kelvin Wong stated that since early March, the overall trend of the 10-year US Treasury yield has remained in a medium-term upward phase. Therefore, at this juncture, gold bulls may not be as aggressive in pushing prices higher. Gold is expected to continue weakening over the next few trading days, with resistance at $4,645 and support at $4,456. (Jin10 Data) Goldman Sachs stated that central banks are expected to increase gold purchases, helping gold prices rebound by year-end. Analysts Thomas, Lina and Struyven, Daan stated in a research report published on May 15 that the average monthly central bank gold purchases in 2026 are expected to rise to 60 mt. Based on the revised accumulation model, the 12-month average of central bank gold purchases in March reached 50 mt, compared with a previous figure of 29 mt. Citing internal surveys, the analysts noted that central banks have long-term rigid allocation demand for gold, and recent changes in the geopolitical landscape are likely to continue driving countries to accelerate asset diversification. JPMorgan lowered its 2026 average gold price forecast from $5,708 per ounce to $5,243 per ounce. As demand is expected to re-accelerate in H2 2026, the base case still projects gold prices reaching $6,000/ounce by year-end.
