British Columbia plans to invest up to CAD 1 million to support field testing of wildfire prevention technology developed by Skyward Wildfire Technologies using aluminum nanoparticle-based materials. The system disperses silica or basalt fibers coated with aluminum nanoparticles into storm systems to redistribute electrical charges and reduce lightning strikes that may trigger wildfires. The company also uses AI-based forecasting tools to identify high-risk areas for targeted deployment. Provincial data showed nearly 70% of wildfires in 2024 were caused by lightning, accounting for 97% of the total burned area. The project could support wider deployment across Canada in the future.

Samsung Electronics' South Korea union said on Friday that the tech giant had proposed resuming talks without any preconditions. This came days after government-mediated negotiations over wages and bonus packages broke down. The union said it was willing to hold talks after June 7, but maintained its plan to strike starting May 21; the strike could disrupt production operations at the world's largest memory chip maker. Samsung Electronics issued a statement confirming its proposal to hold unconditional talks, but did not immediately provide further comment. The Samsung union had said on Thursday that it would be willing to sit down for negotiations if the company could submit a detailed proposal addressing the union's demands before 01:00 GMT Friday (9 a.m. Beijing time).

[SMM Morning Meeting Minutes: A Zinc Smelter in Peru Shut Down After a Fire; LME Zinc Logged Eight Consecutive Gains] Overnight, LME zinc opened at $3,558.5/mt. In early trading, LME zinc briefly moved lower to test a low below $3,542.5/mt, after which bears reduced open interest. LME zinc then rallied to a multi-year high, reaching above $3,633.5/mt. The center then pulled back slightly, and it finally closed higher at $3,587/mt, up $35/mt, a gain of 0.99%. Trading volume fell to 14,070 lots, and open interest decreased by 139 lots to 242,000 lots.

Overnight, the most-traded SHFE lead 2606 contract opened at 16,590 yuan/mt, briefly touched a high of 16,620 yuan/mt at the beginning of the session before fluctuating downward, hitting a low of 16,530 yuan/mt near the close, and finally settled at 16,535 yuan/mt, down 0.33%. On the macro front: India restricted duty-free gold imports; Ukraine reported the largest Russian airstrike since the conflict began; Israel and Lebanon held a new round of negotiations in the US. OPEC+ reportedly plans to continue increasing production, targeting the restoration of all production cuts by the end of September. US Treasury Secretary Bessent: the oil price curve is expected to decline within six months; Iran has exhausted its oil storage capacity and will be forced to halt production. China's Ministry of Commerce: China is willing to work with the US to continuously expand the cooperation list. Ministry of Foreign Affairs: China is willing to work with the US to translate the new positioning of China-US relations into actions moving in the same direction. The PBOC: a 300 billion yuan outright reverse repo operation with a 6-month tenor will be conducted on May 15. : Driven by the LME lead rally, SHFE lead rebounded relatively, and suppliers actively made shipments while lowering quoted premiums. Additionally, primary lead smelter supplies were ample, with mainstream production areas quoted at parity with the SMM #1 lead average price on an ex-factory basis. Secondary lead side, losses remained prominent, and smelters held prices firm while shipping, with secondary refined lead quoted at parity with the SMM #1 lead average price on an ex-factory basis. Meanwhile, the lead-acid battery market remained in an off-season state, with limited just-in-time procurement from downstream enterprises. After lead prices rebounded, inquiry enthusiasm weakened, with buyers only maintaining just-in-time procurement, and spot market transactions turned sluggish. Inventory: On May 14, LME lead inventory decreased by 50 mt to 265,250 mt; SMM five-region lead ingot social inventory increased by approximately 6,100 mt WoW. Lead price forecast for today: Today is the delivery day. Suppliers continued to transfer lead ingots to delivery warehouses, and lead ingot social inventory continued to accumulate. Notably, the domestic market has recently underperformed the overseas market for lead prices. The lead ingot import window has entered a closed state this week. Meanwhile, the supply gap for high-grade lead ingots in Southeast Asia remained significant, with spot cargoes maintaining high premiums. In H2, the potential opening of the lead ingot export window and its impact on domestic lead price trends may be worth watching.

SMM Nickel News, May 8: Macro and market news: (1) The US Central Command issued a statement saying that a US Navy guided-missile destroyer group intercepted an unprovoked attack launched by Iran while transiting the Strait of Hormuz toward the Gulf of Oman, and immediately took self-defense countermeasures. Targeted strikes were also conducted against Iranian military facilities. (2) According to statistics from the State Administration of Foreign Exchange, as of the end of April 2026, China's foreign exchange reserves stood at $3,410.5 billion, up $68.4 billion from the end of March, an increase of 2.05%. In April 2026, affected by macroeconomic data, monetary policies and expectations of major economies, the US dollar index declined, and global major financial asset prices showed divergence. Spot market: On May 8, SMM #1 refined nickel prices fell 1,800 yuan/mt from the previous trading day. Spot premiums: Jinchuan #1 refined nickel averaged 1,150 yuan/mt, flat from the previous trading day; domestic mainstream brand electrodeposited nickel ranged at -800-200 yuan/mt. Futures market: The most-traded SHFE nickel 2606 contract opened lower and continued to decline, extending the downward trend, closing at 146,450 yuan/mt, down 1.94%. Trump explicitly stated on the evening of May 6 that a US-Iran deal was "very likely," with the negotiation framework largely finalised, passage through the Strait of Hormuz expected to resume, and the sulphur supply crisis likely to be resolved, leading to a sharp pullback in nickel prices. In the short term, the most-traded SHFE nickel contract is expected to move sideways within the range of 145,000-150,000 yuan/mt, with the center likely shifting downward, and the key support below coming from the rigid cost support brought by Indonesia's new HPM policy.

[SMM Lead Morning Meeting Minutes: Geopolitical Tensions Resurface Outside China, Lead Prices to Give Back Some Gains] Tensions rise again in the Strait of Hormuz: Iran accused the U.S. of violating the ceasefire by launching airstrikes on Iranian coastal areas and oil tankers.

ArcelorMittal Kryvyi Rih (AMKR) has announced a temporary suspension of its steel and rolled product manufacturing for at least four days, starting May 5, 2026, due to critical damage to the railway infrastructure connecting the plant to Black Sea ports. The logistics bottleneck, caused by repeated strikes on the Odesa-Chornomorsk bridge, has paralyzed the export of iron ore concentrate and finished steel, forcing the company to idle Blast Furnace No. 6. While the plant aimed for a 2026 production target of 5.3 million metric tons (mt) of iron ore concentrate and 3.8 million mt of crude steel, this disruption threatens to tighten the supply of long products in the European and North African markets.

Editor's Note: During the Labour Day holiday when the Chinese market was closed, global macro developments, commodity markets, and ex-China policy dynamics continued to evolve, with multiple external factors potentially impacting post-holiday market performance. To help market participants accurately grasp market trends and conduct rational market analysis, SMM has systematically compiled key macro developments and major industry news during the holiday, along with a summary of this week's critical data and event periods, for industry reference. Internationally, geopolitical developments, energy landscape, ex-China monetary policy, and trade policy all saw significant changes. Geopolitical tensions resurfaced, intermittently disrupting global energy markets and briefly driving international oil prices into a rapid short-term rise. Major global central bank policies continued to diverge. The US Fed released its latest policy signal — New York Fed President Williams publicly stated on Monday that if inflation continues to pull back toward the 2% policy target, the US Fed will cut interest rates at an appropriate time. Meanwhile, the Reserve Bank of Australia announced its third consecutive rate hike on Tuesday, raising the cash rate from 4.1% to 4.35%, officially reversing its previous accommodative monetary policy cycle, further widening the divergence in global liquidity landscape. On the energy export front, according to Bloomberg on May 4, US crude oil exports continued to climb over the past nine weeks, with cumulative exports exceeding 250 million barrels, surpassing Saudi Arabia to reclaim the position of the world's largest crude oil exporter. Global trade and foreign exchange markets also saw notable shifts. In trade, according to CCTV News, on May 1 local time, US President Trump stated that due to the EU's failure to fulfill a previously agreed trade deal, the US would impose additional tariffs on automobiles and trucks imported from the EU next week, raising the rate to 25% — subsequent changes in the global trade landscape warrant continued attention. In the foreign exchange market, Japan intervened in the currency market three times between April 30 and May 4. A relevant official from Japan's Ministry of Finance simultaneously interpreted related IMF rules, explicitly classifying the three-day intervention operations as a single operation, with a clear intent to stabilize the yen exchange rate. On industrial policy, Indonesia introduced resource export control measures, planning to levy export taxes and windfall taxes on coal and nickel products, which may impact global energy and non-ferrous metal supply chains, pricing systems, and related commodity markets. This week, major economic data in and outside China will be released in quick succession. Highly watched data including China's foreign exchange reserves, gold reserves data, China's import and export data (TBD), and US April non-farm payrolls data will be published sequentially. Meanwhile, SMM will comprehensively review price movements across metal categories during the holiday, and combining the latest variables in and outside China, is expected to publish post-holiday market trend outlooks to provide professional reference for industry trading, production, and strategic planning. Stay tuned. ※Holiday Macro News ►Domestic [Baiyun Airport Port Sees Record-High Canton Fair Foreign Arrivals Exceeding 540,000] On the last day of the Labour Day holiday, coinciding with the closing of the 139th Canton Fair, reporters learned from the Baiyun Border Inspection Station that since the opening of this Canton Fair, as of 0:00 on May 5, Baiyun Airport port handled over 1.14 million inbound and outbound passengers, up 14.5% YoY.

The US Court of International Trade had previously expected refunds to start on May 11, but this has been delayed by one day for undisclosed reasons. (CCTV News) [Senior Iranian Commander: Iran Is Controlling the Strait of Hormuz, US Cannot Reverse the Current Situation] Senior commander of Iran's Islamic Revolutionary Guard Corps Yadollah Javani confirmed in an interview on May 4 that Iran is controlling the Strait of Hormuz, that any passing vessel must obtain Iranian permission to ensure safe passage, and that hostile forces' ships attempting forced transit will be dealt with resolutely. Yadollah Javani dismissed US President Trump's claim of "clearing" the strait's shipping lanes for humanitarian reasons as a lie, stating that Iran would prevail if the confrontation escalated. He said the US could never restore the situation to before February 28, nor reverse the current state of affairs. (CCTV News) [Trump refuses to confirm whether US-Iran ceasefire agreement remains in effect] On May 4, US President Trump refused to clarify whether the ceasefire agreement between the US and Iran remained in effect during an interview. When asked whether the ceasefire had ended and whether military strikes could resume, Trump said: "I can't tell you that. If I answered, you'd say this guy isn't smart enough to be president." Earlier that day, Trump warned in an interview that if Iran attempted to attack US ships in the Strait of Hormuz or the Persian Gulf, they "will be totally destroyed." However, he subsequently stated that from a military standpoint, the conflict with Iran was "essentially over." (CCTV) [Qatar condemns attack on UAE oil tanker in Strait of Hormuz] Qatar's Ministry of Foreign Affairs issued a statement on the 4th, strongly condemning a drone attack on an oil tanker operated by Abu Dhabi National Oil Company of the UAE while passing through the Strait of Hormuz, calling it a serious violation of international law and the principle of freedom of navigation. The statement said Qatar firmly opposes using the Strait of Hormuz as a pressure tool, called for the unconditional reopening of the strait, and emphasized that freedom of navigation through this vital waterway is an established principle that cannot be compromised. The statement noted that the continued closure of the strait would jeopardize the vital interests of countries in the region. Qatar's Ministry of Foreign Affairs reaffirmed its support for all measures taken by the UAE to protect its assets. (Xinhua) [US Fed "No. 3" speaks: Interest rate cuts will eventually come if inflation pulls back, but timing has been forced to delay] New York Fed President Williams publicly stated on Monday that as long as inflation pulls back toward the US Fed's 2% target as expected, the US Fed will eventually need to cut interest rates . However, due to inflation running higher than expectations this year, the timing of interest rate cuts has been forced to delay, though the overall policy direction has not fundamentally changed. Williams told reporters after delivering a speech in New York on Monday: "As inflation moves lower, we will eventually need to cut interest rates at some point to match fundamentals. Inflation has been higher than previously expected this year, and in my view, this only delays the timing of rate cuts and does not change the overall policy logic." Last week, the US Fed decided to keep the benchmark interest rate unchanged, but internal policy disagreements became prominent, with three officials opposing the easing bias implied in the meeting statement, preferring more neutral language to release signals that rates could move either up or down going forward. Regarding the controversial wording, Williams was clear in his stance: he fully endorsed the current statement's language, believing that based on day-to-day economic data, there was no sufficient reason to support a rate hike in the short term. [IMF Chief Warns: Prolonged Middle East Conflict Could Trigger More Severe Inflation and Growth Shocks] The head of the International Monetary Fund (IMF) warned that inflation has begun to intensify, and if the Middle East war continues into 2027 with oil prices rising to around $125 per barrel, the global economy could face a "worse scenario." IMF Managing Director Georgieva stated that the continuation of the war means the organization's previous assumption of only a mild slowdown in global economic growth and only a slight edge up in prices no longer holds. Therefore, the "adverse scenario" set by the IMF has effectively begun to materialize. Speaking at a conference hosted by the Milken Institute, Georgieva noted that long-term inflation expectations remain anchored for now and financial conditions have not yet tightened, but this could change if the war persists. [RBA Raises Rates by 25 Basis Points as Expected — Entering Wait-and-See Mode After "Triple Hike"?] The Reserve Bank of Australia (RBA) announced its third consecutive rate hike on Tuesday, raising the cash rate from 4.1% to 4.35%, completely reversing last year's monetary easing cycle. The move underscored the central bank's determination to suppress stubborn inflation, making it an outlier among major global central banks — decisively embarking on a new tightening cycle while the US-Iran conflict fueled uncertainty and many central banks chose to stand pat. The RBA's nine-member policy committee approved the rate hike with a vote of 8 in favor and 1 against . RBA Governor Michele Bullock will hold a press conference at 1:30 PM Beijing time to explain the policy decision. The committee emphasized in its statement: "After three rate hikes, monetary policy now has sufficient room to respond to changing conditions , and the committee will focus on its dual mandate of price stability and full employment, taking all necessary measures to achieve its objectives." [Japan Intervened to Boost Yen on "3 Consecutive Days" During Holiday, Claims It "Counts as 1" Under IMF Rule of "Maximum 3 Interventions Within 6 Months"] Japan intervened in the foreign exchange market on three consecutive days during Golden Week, but Japanese officials promptly cited IMF rules stating that the three actions "count as one" — a statement reflecting the government's careful calculation of intervention frequency. A Ministry of Finance official told reporters on May 5 that under relevant IMF regulations, foreign exchange market interventions over three consecutive business days are considered a "single action."The official made the above remarks while accompanying Finance Minister Satsuki Katayama at an international conference held in Samarkand, Uzbekistan. By this calculation, the three interventions on April 30, May 2 (Friday), and May 4 (Monday) were counted as one combined action. The official added that even when Japan was on public holiday, interventions could still be counted as long as global markets were open; May 4 was therefore recognized as the last of three consecutive business days starting from April 30. This round of intervention began on April 30, triggered when USD/JPY broke above 160.72. According to Bloomberg's analysis, authorities deployed approximately $34.5 billion that day to support the yen, and the exchange rate rebounded to around 155. However, the effectiveness of the subsequent two interventions diminished notably—the yen briefly strengthened after each intervention before pulling back again. The two subsequent interventions reportedly cost a combined approximately $20 billion. In total, the three interventions in this round are estimated to have exceeded $54 billion in scale. ※Industry News and Corporate Developments [Indonesia Plans to Impose Export and Windfall Taxes on Coal and Nickel to Ease Subsidy Pressure] Indonesia plans to impose export taxes and windfall taxes on coal and nickel as one of the measures to offset the growing subsidy costs in the national budget. Indonesia's Finance Minister Purbaya Yudhi Sadewa stated that the proposed measures are still under discussion with the Ministry of Energy and Mineral Resources. "Discussions with the Energy Ministry are ongoing, but what is clear is that the related revenue will be sufficient to help bridge the subsidy gap." Purbaya noted that coal and nickel exports had not previously been subject to export taxes, creating regulatory loopholes that could foster under-invoicing and smuggling, while also limiting customs authorities' ability to inspect goods before shipment. The implementation of export taxes is expected to grant the Directorate General of Customs and Excise (DJBC) greater authority to conduct inspections before goods are exported, thereby helping to close tax loopholes and prevent fiscal leakage. (Wallstreetcn) [250 Million Barrels of Crude Oil Shipped Outside China, US Inventory Falls for Four Consecutive Weeks—How Long Can the World's "Last Supplier" Hold Out?] Over the past nine weeks, a large number of tankers sailed intensively toward the US, loading up along the coast of Alaska and the Gulf of Mexico before heading to destinations such as Japan, Thailand, and even Australia. During this period, the US cumulatively exported over 250 million barrels of crude oil outside China, once again surpassing Saudi Arabia to become the world's largest crude oil exporter. Against the backdrop of the Strait of Hormuz nearing shutdown and Middle Eastern supply disruptions, the US has effectively assumed the role of a critical global energy source. However, this rapid surge in export volume also exposed potential risks. US domestic inventory has been declining notably, with total crude oil and refined product reserves falling for four consecutive weeks and dropping below historical averages, while the production side also faced pressure to maintain output. (Jin Shi Data) [Trump: US Is Taking "Hundreds of Millions of Barrels of Oil" from Venezuela] On May 4, US President Trump spoke at a small business summit on the topic of energy cooperation with Venezuela.

On April 24, the SMM Imported Copper Concentrate Index (weekly) stood at -81.44 USD/dmt, down 2.83 USD/dmt from the previous reading of -78.61 USD/dmt. The deeply negative TC reflects the tightness in the global copper concentrate market, which has already shifted from market expectations to an actual rigid contraction in supply. In the first quarter of 2026, the world's leading mining companies frequently revised down their production guidance, with supply-side disruptions far exceeding early-year forecasts. Freeport significantly lowered its full-year 2026 copper production forecast from 1.542 million tonnes to approximately 1.406 million tonnes, with an expected recovery rate of only 65%, due to slower-than-expected mine recovery at its Grasberg site in Indonesia, affected by mudslides and ore moisture. In addition, road blockades caused by strikes at BHP's Escondida and Zaldivar mines have led to actual production impacts that remain to be monitored. According to SMM exclusive data, the global copper concentrate deficit in 2026 is estimated at 317,000 metal tonnes, a situation that may ease somewhat in 2029. In stark contrast to the persistently falling TC, domestic smelter operating rates remained high in Q1 2026. According to SMM data, China's electrolytic copper output in March 2026 reached 1.2061 million tonnes, up 5.58% month-on-month and 7.49% year-on-year. In Q1 2026, total electrolytic copper output was 3.5278 million tonnes, up 4.60% quarter-on-quarter and 10.45% year-on-year. SMM survey data shows that 11 smelters have confirmed maintenance schedules for Q2 2026. This means that domestic electrolytic copper output is expected to decline in Q2, with spot supplies likely tightening temporarily in May and June. However, some smelters have reported that due to high sulfuric acid prices, maintenance completion times may be brought forward. Sulfuric acid is currently the most important by-product revenue source for the copper smelting industry. According to SMM data, on April 24, 2026, China's copper smelting acid index stood at 1,660.5 RMB/ton, up 31.5 RMB/ton from the previous period. As sulfuric acid revenues have risen steadily from 890 RMB/ton at the start of 2026 to 1,660.5 RMB/ton in April 2026, based on the co-production of 3–4.5 tonnes of sulfuric acid per tonne of electrolytic copper, sulfuric acid income can now cover the copper concentrate procurement cost and part of the processing cost for smelters. The upward slope and magnitude of this increase exceed the deterioration in spot TC. The substantial boost in sulfuric acid profitability allows smelters to tolerate lower TC, creating a cycle of "higher sulfuric acid prices, lower TC." Meanwhile, rising gold and silver prices have further expanded smelters' comprehensive profit margins. Although the copper smelting segment is deeply loss-making, driven by the hefty profits from sulfuric acid, gold, and silver, domestic copper smelters have been able to maintain high operating rates without large-scale production cuts caused by deeply negative TC. Additionally, about 20% of the world's electrolytic copper comes from hydrometallurgical processes, with the DRC and Chile together accounting for nearly 80% of that. Hydrometallurgical copper production consumes large amounts of sulfuric acid, and sulfur is a key raw material for sulfuric acid. The current disruption in the Strait of Hormuz has cut off approximately 50–60% of Middle Eastern sulfur shipments by sea, pushing up sulfur and sulfuric acid prices. Worth noting is that as late April 2026 progresses, sulfuric acid export restrictions combined with increased domestic production have shown signs of price softening. If sulfuric acid prices continue to decline, it will directly squeeze the comprehensive profit margins of domestic smelters. At that point, the dual pressure of persistently low TC and falling sulfuric acid prices could trigger real production cuts on the smelting side. Although gold and silver prices do not directly determine TC trends, their macro-pricing logic as part of the non-ferrous metals sector is worth attention. The market has largely priced in the expectation that the Federal Reserve will not cut interest rates at all in 2026, with the first rate cut possibly delayed until July 2027. For copper, a delayed rate cut means no near-term easing of macro liquidity, but copper's core pricing logic remains the ongoing tug-of-war between tightening supply on the mining side and rigid demand. In other words, precious metals are under pressure, but industrial metals' pricing center remains in real supply-demand fundamentals, which explains why weaker gold and silver prices have not dragged copper prices lower. According to SMM, for Chinese smelters, domestic copper concentrate spot TC transactions are feasible in the range of -81 USD/dmt to -88 USD/dmt. Some holders have attempted to offer TC at -100 USD/dmt, while some smelters are willing to accept deliveries at the lower end around -90 USD/dmt. The downward trend in TC has not yet stopped, and smelter purchasing activity may have weakened slightly, but not significantly. Key areas to watch moving forward: Sulfuric acid side: The price trend will depend on the interplay of multiple factors. First, China's sulfuric acid export policy direction: if export restrictions continue, domestic sulfuric acid supply will be relatively abundant, and prices may fall from highs; if exports are temporarily allowed, overseas hydrometallurgical copper supply risks will rise, but domestic sulfuric acid prices may find support. Second, the recovery of sulfur supply: when shipping through the Strait of Hormuz returns to normal will directly affect the pace at which Middle Eastern sulfur can supplement global markets. Third, seasonal demand changes for downstream products such as phosphate fertilizers will also cause periodic price volatility for sulfuric acid. Mining side: Focus on the progress of the Grasberg conversion project, labor negotiation results at Chilean mines, and logistics stability at mines such as Las Bambas in Peru. Any new supply release will effectively ease TC pressure. Macro side: Monitor the Federal Reserve's monetary policy path, the U.S. dollar index, the actual driving effect of China's pro-growth policies on copper consumption, and whether the growth rate of copper demand in global new energy sectors is slowing marginally.
