"Tin" Leads the Future: Industrial Transformation and Value Reshaping in a New Cycle **Conference Background** Currently, the global tin industry stands at a historic turning point, where traditional cyclical logic has been fundamentally disrupted and strategic value has become fully prominent. The tin market in 2026 presents an unprecedented complex pattern and profound transformation: **I. Deep Restructuring of the Supply-Demand Pattern with Unprecedented Elevation of Strategic Attributes** The global static reserve-to-production ratio of tin resources is only 14 years, with scarcity becoming increasingly prominent. The supply side faces "triple pressures": repeated setbacks in Myanmar's production resumptions, continued tightening of Indonesian policies, and elevated geopolitical risks in the DRC — resource constraints have become the new normal. Meanwhile, the demand structure has undergone a fundamental shift, and tin has become a strategic resource connecting traditional manufacturing with the digital future. **II. Price System Breaking Historical Records with the Industrial Ecosystem Facing Reshaping** In early 2026, SHFE tin prices broke through 470,000 yuan/mt, hitting a record high. This price breakthrough is not only a reflection of supply-demand imbalance but also a hallmark of value reassessment for the tin industry. Traditional trade models, risk management systems, and supply chain collaboration approaches all urgently require innovative breakthroughs. **III. Technology-Driven and Green Transformation Fostering a New Symbiotic Ecosystem** Digital and intelligent technologies are deeply empowering the tin industry chain. The global green transformation requires the tin industry to upgrade toward low-carbonisation and circular economy models, making recycled tin recovery and green smelting processes an inevitable path. All segments of the industry chain must shift from competition to collaboration, building an open, resilient, and innovative symbiotic system. Against this backdrop, the 2026 SMM (16th) Tin Industry Chain Conference , to be held on August 19-21 in Changsha, Hunan , will bring together global industry elites for in-depth discussions.

Israel opposed the agreement, preparing for high-intensity operations and demanding the dismantlement of Iran's nuclear facilities. The next round of talks may be held on June 5. Market expectations for a US-Iran deal warmed, exerting a bullish impact on copper prices. Fundamentals side, supply side, arrivals of imported sources remained relatively low, domestic source arrivals edged up, and the tight supply pattern improved marginally.

Harita Nickel plans to launch a share buyback of up to Rp 1 trillion, subject to shareholder approval. The company said the move is intended to enhance shareholder value because the current share price does not fully reflect its fundamentals. Against a backdrop of volatility in nickel sector valuations, the planned buyback is also seen as a step to support market expectations and reinforce shareholder returns.

Trimegah Bangun Persada, also known as Harita Nickel (NCKL), plans to carry out a share buyback of up to Rp 1 trillion over the next 12 months after its annual general meeting on June 30, 2026. The company said the buyback is intended to support shareholder value because the current market price does not yet reflect the company’s underlying fundamentals. NCKL shares rose more than 1% to Rp 860 on Monday.

Supply-demand fundamentals of hot-rolled coil side, maintenance in early to mid-June will have limited impact and will drive hot-rolled coil supply to rebound. Demand is unlikely to deliver impressive performance against the backdrop of an overall off-season for steel consumption. SMM expects hot-rolled coil inventory to continue destocking in early to mid-June, with the pace of inventory decline expected to slow down in late June, with a probability of inventory buildup. Supply-demand imbalance accumulation will be limited in early to mid-June. Attention should be paid to the subsequent impact from the raw material side and export order-taking conditions.

In April 2026, domestic lead prices overall moved sideways, with spot cargo and futures trends remaining relatively stable. According to SMM data, the average spot price of SMM #1 lead ingot in April was 16,525 yuan/mt, with prices operating steadily within the range during the month, rising first then declining.

[SMM Coking Coal and Coke Daily Brief] News: Some steel mills raised wet-quenched coke prices by 50 yuan/mt and coke dry quenching prices by 55 yuan/mt, effective from midnight on May 26, 2026. Supply side, coke producers remained profitable with moderate production enthusiasm, and coke production stayed relatively stable. Coke producers actively pushed shipments, keeping their own coke inventory at reasonable levels. Demand side, steel mill blast furnace daily average hot metal production fluctuated at highs, providing strong rigid demand support for coke. However, under the influence of the traditional off-season, steel mills' restocking pace slowed down somewhat. In summary, mine accidents have increased coking costs, and the coke market is expected to hold up well in the short term, with the fourth round of coke price increases set to be implemented soon.

SMM, May 25: During the session, the most-traded SHFE lead 2607 contract opened at 16,770 yuan/mt. SHFE lead prices fluctuated upward in early trading, touching a high of 16,820 yuan/mt, before pulling back under pressure mid-session, dipping to a low of 16,705 yuan/mt, then moving sideways within the 16,715-16,745 yuan/mt range. Prices rebounded slightly near the close but with limited gains, ultimately settling at 16,755 yuan/mt, marking a four-day winning streak, up 20 yuan/mt or 0.12%. Currently, imported lead supplies have shrunk and domestic lead ingot inventory has pulled back, providing fundamental support for lead prices. However, multiple secondary lead enterprises resumed production in late May, with market supply becoming looser MoM from early May, exerting bearish pressure on prices. Overall, lead prices are expected to maintain a fluctuating trend with limited upside momentum.

(People's Daily) [PBOC Reverse Repo Operations Result in Net Injection of 257 billion yuan Today] The PBOC conducted 258 billion yuan of 7-day reverse repo operations in the open market, with an operation rate of 1.40%, unchanged from the previous day. 1 billion yuan of reverse repos matured today. On the US dollar: As of 11:38, the US dollar index fell 0.3% to 99.03. Kevin Hassett, chief economic adviser to US President Trump, said he believes that the eventual decline in oil prices will create room for the Fed to cut interest rates. "We again expect that once a deal is reached, energy prices will plunge," Hassett said. "When that happens, the Fed will have plenty of room to take the right action and lower interest rates." He emphasized that he respects the Fed's independence and praised Kevin Warsh, who was sworn in as Fed Chairman last Friday. Although the surge in US fuel prices caused by Iran's closure of the Strait of Hormuz poses a growing political risk to Trump and his Republican Party in the November midterm elections, Hassett believes that the accelerating inflation is mainly driven by energy prices. "If you look at the last few data reports, energy prices are absolutely concerning, but core prices have barely moved at all," he said. "I think once we see energy prices pull back, due to declining energy prices, you may actually see negative inflation." (Jin10 Data) According to CME's "FedWatch": the probability that the Fed will keep interest rates unchanged in June was 97.3%, and the probability of a cumulative 25-basis-point rate hike was 2.7%. The probability that the Fed will keep interest rates unchanged in July was 84.8%, the probability of a cumulative 25-basis-point rate hike was 14.8%, and the probability of a cumulative 50-basis-point rate hike was 0.3%. (Jin10 Data) On data: Today, data including China's year-to-date installed power generation capacity in April and its year-on-year rate will be released. In addition, attention should be paid to: 500 billion yuan of 1-year medium-term lending facility (MLF) and 1 billion yuan of 7-day reverse repos will mature today. In addition, it is worth noting that due to the Memorial Day holiday, US stock markets will be closed for one day on May 25 (Monday); CME's precious metals and US crude oil futures contract trading will end early at 02:30 Beijing time on the 26th, and US stock and US Treasury futures contract trading will end early at 01:00 Beijing time on the 26th. Due to the Buddha's Birthday holiday, Hong Kong stock markets will be closed for one day on May 25 (Monday), with both southbound and northbound trading suspended; South Korean stock markets will also be closed for one day on the same day. In addition, due to the Spring Bank Holiday, the UK stock market will be closed on Monday, May 25; trading of ICE Brent crude oil futures contracts will end early at 01:30 Beijing time on May 26. Investors are advised to take note. (Jin10 Data) Overseas exchange closure arrangements are as follows (all in Beijing time): Crude oil: As of 11:38, oil prices in both markets fell, with WTI down 5.92% and Brent down 5.32%. Rising expectations of a US-Iran deal boosted global risk sentiment, putting oil prices under pressure. The direct catalyst for the oil price decline was signs of improvement in actual transit conditions through the Strait of Hormuz. According to Iran's Islamic Republic News Agency citing a statement from the Islamic Revolutionary Guard Corps, 33 vessels — including oil tankers, container ships, and other commercial vessels — passed through the Strait of Hormuz within 24 hours on Sunday after receiving authorization from the IRGC Navy. (Wallstreetcn) The Washington Post reported on May 24 that the US and Iran had reached agreement on a framework for a memorandum of understanding (MOU), which, once signed, would fully restore shipping through the Strait of Hormuz within 30 days. Citing an anonymous senior US government official, the report said the US and Iran had developed an MOU "framework" that includes a 60-day ceasefire extension to allow both sides to reach a "final agreement" on permanently ending hostilities with Iran, during which the Strait of Hormuz would be demined and reopened. The official said the MOU includes a "commitment" that Iran will not possess nuclear weapons. Over the next two months, the US and Iran will discuss the "mechanism" for implementing this commitment. However, neither side signed any agreement on May 24. (Xinhua) Trump said on social media on Saturday that a US-Iran deal was largely done, including the opening of the Strait of Hormuz, and told US representatives not to rush into a deal. But on Sunday he said the deal was "not fully done yet." US Secretary of State Marco Rubio had previously said there could be "some good news" on the Hormuz issue in the coming hours. Iran remained cautious. Iran's Tasnim News Agency warned that the draft agreement could still collapse due to US obstacles on several key terms — including Iran's demand for unfreezing assets.
