Central Asia Metals (CAML) announced that, thanks to improved operational efficiencies, its copper and zinc production for the first five months of 2026 both surpassed the same period last year. Copper output from the Kounrad operation in Kazakhstan totalled 5,141 tonnes, a near 4% increase over the last year. Meanwhile, the Sasa mine in North Macedonia produced 7,566 tonnes of zinc in concentrate, up over 2% compared to last year. In terms of pricing, the company reported significantly higher realized metal prices during the period. The average price of copper reached $13,076 per tonnes, representing a massive jump of nearly 40% over the last year, while average zinc prices rose 19% to $3,299 per tonne. In addition, historically low treatment charges for lead, which have turned negative, further boosted Sasa’s revenues. CEO Gavin Ferrar noted that the group is shaping up to deliver strong profitability and cash generation in the first half of 2026. Currently, the company is actively pushing forward with its acquisition of Australia's Cygnus Metals, announced last week, to expand its footprint into a high-grade copper-gold project in Quebec, Canada. The company remains highly confident in meeting its full-year production guidance (12,000–13,000 tonnes of copper, 18,000–20,000 tonnes of zinc concentrates, and 26,000–28,000 tonnes of lead concentrates).

SMM News Flash: [Rebar] Today, export FOB prices for rebar rose slightly by about USD 2/tonne. According to market traders, inquiry activity was relatively decent, but actual transactions remained average. Some participants also noted that long steel demand in South America has been relatively stable recently, while demand in the Middle East remains weak. Regarding the US–Iran peace agreement, there has been no significant change in order flow so far, and overall market sentiment remains cautious and wait-and-see. [Billet] Today, export billet offers increased slightly by around USD 2/tonne, with prices at approximately USD 473–476/tonne FOB. Market feedback indicates that countries such as Indonesia and India are actively exporting billets, leading to intensified competition. However, domestic export price advantages are not obvious, as rising production costs are limiting steel mills’ willingness to discount, while traders are also more cautious in taking short positions. As a result, overall transaction activity remained moderate. [HRC] Today, export prices for flat steel products rose by USD 2/tonne day-on-day. Hot-rolled coil transaction prices were in the range of USD 497–506/tonne. Market inquiry activity was moderate, with no significant release of concluded deals. Recently, there have been some new inquiries for medium and heavy plate in the Middle East, with a portion of them resulting in transactions. [India] Ship-breaking scrap prices in the Alang (Gujarat) market increased by around 3 USD/tonne, with HMS (80:20) assessed at approximately 373 USD/tonne EXW. Semi-finished steel prices remained broadly stable, while finished steel saw a mild correction in the previous trading session. Market sentiment in Alang stayed subdued, as vessel arrivals remained at historically low levels. Strong freight economics continued to incentivize shipowners to extend the operating life of older vessels, limiting scrap inflows. In the near term, Alang scrap prices are expected to remain supported but constrained by tight supply conditions, with further movement largely dependent on vessel arrivals and downstream steel demand. [Thailand] Galvanizing quotes in the Thai market remained stable in the short term, with import offers still around 710 USD/tonne; however, for large-volume firm orders, the market could consider offering a discount of 5-10 USD/tonne. Wire rod quotes were also relatively stable, but some traders had to push up prices by 20 USD/tonne to 570 USD/tonne due to rising costs. In terms of local market transactions, downstream end-use demand was weak, and actual deals mostly shifted to a "negotiate deal by deal" model. It is expected that in the short term, Thai wire rod and galvanizing prices will hover at highs. Whether prices can subsequently stabilize on a solid footing will mainly depend on the release of downstream firm orders and the final bargaining and concession room offered by sellers under shipment pressure. [South Korea] Facing the approaching rainy season, South Korean builders are racing against time to push forward the final “intensive rush to meet deadlines” for foundation and main structure works, and the upward momentum of finished steel prices has slowed significantly. Today, POSCO’s two core steelworks (Pohang and Gwangyang) simultaneously raised the purchase price of high-quality pig iron scraps/premium steel scrap by 15,000 won/tonne (approximately 9.93 USD/tonne), and medium and light scrap by 10,000 won/tonne (approximately 6.62 USD/tonne), mainly to prevent domestic supply from being snapped up by other EAF steel mills before the off-season arrives. POSCO had no choice but to raise buying prices against the trend to “lock in” domestic spot cargo flows.

A University of Michigan survey showed that the preliminary US consumer sentiment index for June rose to 48.9 from a record low of 44.8 in May, marking the first rebound in nearly four months, though still at a historically low level. Thanks to the recent pullback in oil prices, consumers' one-year inflation expectations pulled back from 4.8% to 4.6%.

In May, the global aluminum market continued the core pattern of LME outperforming SHFE with divergent trends. The most-traded SHFE aluminum contract moved sideways in the doldrums, while LME aluminum maintained strength supported by low inventory and geopolitical premiums, with both seeing slight corrections at month-end. This month's market-driving logic revolved around Middle East ceasefire negotiations, rising expectations for US Fed interest rate hikes, divergence in inventory in and outside China, and accelerating export transmission, further highlighting the divergence between domestic and overseas aluminum price trends. The SHFE/LME aluminum price ratio declined further from the April average of 7.03 to the May average of 6.66, with the inverted price spread between domestic and overseas markets widening, as the trend of overseas aluminum prices outperforming SHFE aluminum continued to deepen. May Aluminum Price Review: Similar Pace but Intensifying Divergence in Strength China · The Most-Traded SHFE Aluminum Contract The contract opened low at around 24,800 yuan/mt at the beginning of the month. After the holiday, it pulled back rapidly due to high domestic inventory and weaker-than-expected downstream demand, hitting the monthly low of 24,075 yuan/mt on May 7. In mid-month, it rebounded to 24,620 yuan/mt driven by positive signals from the China-US meeting. In the latter part of the month, it pulled back to 24,375 yuan/mt as ceasefire expectations heated up combined with off-season drag. Ex-China · LME Aluminum The contract opened at $3,480/mt at the beginning of the month. In mid-month, it rallied to $3,680/mt (the monthly high and a four-year high) supported by supply disruptions and continued destocking. At month-end, it corrected to $3,628/mt, impacted by news that a US-Iran ceasefire agreement was 95% reached. In terms of price-driving factors, geopolitics remained the core common variable for aluminum prices in and outside China this month. Production cuts in the Middle East and shipping disruptions through the Strait of Hormuz continued to provide a shortage premium for LME aluminum. The price divergence stemmed from dual differences in macro policy and fundamentals—slow destocking from high inventory levels in China constrained SHFE aluminum's rebound space, while historically low inventory and a high premium structure outside China provided strong support for LME aluminum prices. Core Inventory Indicators: Extreme Divergence Between Domestic and Overseas Inventory with Contrasting Destocking Pace China · Gradual Decline from High Levels, Pressure Persists Social inventory began to pull back from the high of 1.456 million mt at the beginning of May, reaching approximately 1.401 million mt by month-end, with only about 55,000 mt destocked over the entire month. The destocking pace was slow, with inventory remaining at a near six-year high for the same period. SHFE warrants recorded 485,500 mt on May 29, still showing inventory buildup on a weekly basis, confirming ample spot supply in China. Ex-China · 20-Year Low, Structural Deficit Becomes Evident LME total inventory declined from approximately 363,000 mt at the beginning of the month to 338,000 mt at month-end, a decrease of approximately 25,000 mt over the month, with inventory levels at historically extreme lows. LME aluminum Cash-3M premiums closed at $92.53/mt at month-end, widening significantly from approximately $29/mt at the beginning of the month. Japan's Q3 spot premiums rose, premiums in Europe and the US continued to climb, and the rigid supply gap outside China provided sustained and strong support for LME aluminum. Macro and Fundamentals Intertwined: Geopolitical Dynamics and Rate Hike Expectations Dominating Sentiment Geopolitical Variables: Repeated Ceasefire Negotiations At the beginning of the month, the US military launched airstrikes on southern Iran, with military frictions between the two sides recurring. Shipping through the Strait of Hormuz remained disrupted, and geopolitical risk premiums climbed. At month-end, a US-Iran framework agreement was reportedly 95% complete, and a 60-day temporary ceasefire draft emerged. Expectations for the resumption of strait navigation warmed, and geopolitical premiums converged significantly. On the morning of May 28, both SHFE aluminum and LME aluminum plunged. US Fed Expectations: Hawkish Pressure US April CPI came in at 3.4% YoY, with core PCE reaching 2.8%. Inflation stickiness, compounded by Middle East conflicts pushing oil prices above $90/barrel, led hawkish US Fed officials to release signals of "raising rates at any time." Market expectations for a 25bp rate hike within the year surged abruptly, and a stronger US dollar continued to weigh on the demand outlook for non-ferrous metals. IV. Current Core Market Trades and Arbitrage Strategies (Including Divergence in Capital Behavior) Based on the current SHFE and LME fundamentals, inventory pace, and LME curve structure, the aluminum market overall exhibits a cautious unidirectional and arbitrage-dominated trading pattern. In particular, SHFE-LME cross-market reverse arbitrage (selling SHFE and buying LME) has become the core market play. Capital behavior among market participants has shown clear divergence, mainly falling into three categories: 1. Early-positioning capital (light long positions in reverse arbitrage) Some trading capital has positioned reverse arbitrage ahead of time based on the logic that China's inventory inflection point has already appeared. The core expectation of such capital is that as China's inventory gradually enters a destocking channel, accelerated destocking is highly likely to follow, rapidly easing China's high inventory pressure. The weak SHFE aluminum pattern is expected to be corrected, and the depressed SHFE-LME ratio has clear room for recovery, warranting early light positioning to capture the ratio rebound. 2. Wait-and-see cautious capital (staying on the sidelines for now) The majority of market capital has maintained a wait-and-see stance, with two core concerns: First, China is currently only experiencing slow destocking, and its sustainability is questionable during the off-season, as inventory pressure has not been substantially cleared and SHFE aluminum lacks sufficient rebound momentum. Second, LME is currently in a deep backwardation structure, making roll and extension costs for LME aluminum bulls extremely high, with significant cost erosion and high open interest pressure for holding long-term reverse arbitrage positions. Combined with the entrenched short-term pattern of LME outperforming SHFE, the price spread still risks further widening. Therefore, this segment of capital has chosen to wait for confirmed signals of accelerated destocking in China before entering the market. 3. Previously trapped capital (open interest under pressure, caught in a dilemma) Some positions that were established earlier to set up SHFE-LME reverse arbitrage are currently slightly underwater. Recently, LME has been continuously driven higher by geopolitical risks while SHFE has been range-bound and weak, with the divergence between LME outperforms SHFE intensifying, causing the ratio to remain persistently low and unrealized losses to emerge. Meanwhile, LME contango fees have risen sharply, long positions carrying costs continue to increase, and the pressure of holding trapped positions has further intensified. In the short term, these positions are caught in a dilemma, highly dependent on the subsequent pace of China's inventory destocking to restore the spread. Overall, the sole core inflection variable for SHFE-LME reverse arbitrage is currently the pace of domestic inventory destocking. Once weekly inventory drawdowns continue to widen and accelerated destocking is confirmed, it will directly drive a reversal in three types of capital behavior: sidelined capital entering the market en masse, trapped positions getting unwound, and early-entry positions realizing profits, triggering a rapid recovery in the ratio. Looking ahead to June, the aluminum market's core focus centers on three dimensions: first, whether the US-Iran ceasefire agreement can be formally signed and the pace of resuming navigation through the Strait of Hormuz, which will directly determine the extent of geopolitical premium convergence — if the agreement materializes and Middle Eastern aluminum supply gradually recovers, the prior support logic for LME aluminum faces correction risk; second, whether domestic inventory destocking can accelerate — continued export growth and import suppression will keep driving destocking, and the magnitude of destocking will determine SHFE aluminum's upside elasticity. The US Fed's June FOMC meeting is highly likely to keep rates unchanged, but a hawkish tone and sticky inflation will continue to suppress interest rate cut expectations, with a stronger US dollar maintaining sustained pressure on non-ferrous metals. Overall, the aluminum market in June is expected to continue the pattern where LME outperforms SHFE, though the degree of divergence is likely to narrow. LME aluminum is expected to hover at highs amid the tug-of-war between geopolitical premium convergence and rigid ex-China supply deficits, with downside room constrained by low inventory and high premiums.

From January to April 2026, the automotive industry's sales profit margin further declined to 3.4%. April's figure was 3.7%, better than the 3.2% recorded from January to March, but still at a historically low level, with downward pressure on profitability continuing to intensify.

As of May 26, the Shanghai-LME zinc price ratio stood at 6.97, continuing its downward trend from 7.4 recorded in late March, which has led to a widening import loss of refined zinc ingots in China. According to calculations by Shanghai Metals Market (SMM), the current import loss of China’s refined zinc ingots has expanded to approximately RMB 3,800 per metric ton of metal.

Global Aluminum Market Review – April: Divergent Domestic & Overseas Trends and Marked Spot Structure Disparities The global aluminum market in April featured a core pattern of strength overseas and weakness domestically with diverging trends. The main Shanghai aluminum contract retreated from highs amid fluctuations, while LME aluminum maintained firm momentum supported by low inventories and geopolitical factors, with both markets seeing mild corrections toward month-end. Market drivers this month centered on macro policies, geopolitical conflicts, supply-demand fundamentals and inventory structures, with movements of key indicators further highlighting supply-demand imbalances between domestic and overseas aluminum markets. I. April Aluminum Price Review: Linked Movements with Distinct Strength Differentials Shanghai aluminum and LME aluminum shared similar price rhythms in April, both fluctuating higher initially before retreating. However, notable gaps emerged in upward momentum and correction ranges, with overseas aluminum prices significantly outperforming domestic counterparts. The average Shanghai-LME aluminum ratio dropped from 7.36 in March to 7.03 in April, reflecting stronger overseas aluminum pricing relative to Shanghai aluminum. The main Shanghai aluminum contract trended upward early in the month before softening overall, declining from elevated levels through range-bound trading. It opened lower at RMB 24,715 per ton at the start of the month and consolidated. Driven by escalating Middle East geopolitical tensions and rising LME aluminum prices, it surged to a monthly peak of RMB 25,675 per ton in mid-April. In late April, amid continuous domestic inventory accumulation, weaker-than-expected downstream demand, and risk-averse capital outflows ahead of the May Day holiday, prices corrected steadily. Closing at RMB 24,430 per ton on April 30, the contract recorded a monthly trading range of nearly RMB 1,360 per ton. LME March aluminum traded firmly with mild late-month declines. Opening at USD 3,459 per ton, it climbed to a monthly high of USD 3,672 per ton in mid-April, underpinned by overseas supply disruptions from geopolitical frictions and sustained inventory destocking. Prices edged down later due to fluctuating US-Iran negotiations, hawkish macro sentiment and profit-taking at high levels, settling at USD 3,476 per ton at month-end with a slight monthly loss. Overall, LME aluminum vastly outperformed domestic Shanghai aluminum. In terms of price drivers, geopolitics served as a shared upward catalyst for global aluminum prices, with production cuts and supply disruptions in the Middle East continuously boosting market risk aversion. Price divergence stemmed from dual disparities in macro policies and fundamentals: elevated domestic inventories and sluggish demand consistently capped aluminum price rebounds, while tight overseas inventories and strained spot supplies provided robust support for LME aluminum. II. Key Inventory Indicators: Divergent Inventory Movements and Contrasting Supply-Demand Landscapes As a core gauge of aluminum market supply and demand, domestic and overseas inventory trends diverged sharply in April, directly shaping the relative strength of regional aluminum prices. Domestic aluminum inventories kept rising and stood at a multi-year seasonal high. Social inventories maintained an upward trend throughout April, hitting 1.465 million tons in mid-month, the highest seasonal level in five years. A clear imbalance emerged between rigid supply release and lackluster downstream demand during the traditional peak "Silver April" period, leading to persistent spot market loosening. SHFE warehouse stocks expanded from 420,000 tons at the start of the month to 450,000 tons at month-end. Elevated warehouse stock levels further confirmed ample domestic spot supply, weighing continuously on aluminum prices. Overseas LME aluminum inventories declined steadily to a 20-year low. Total LME aluminum inventories fell from 410,000 tons to 370,000 tons in April, extending months of destocking to historic lows. Noticeable structural divergence persisted in inventory composition: Russian aluminum accounted for approximately 92% of total LME stocks in March, resulting in low market-circulating inventories and increasingly tight physical spot supply, which acted as the fundamental pillar for strong LME aluminum prices. In summary, April’s global aluminum market was governed by contrasting core dynamics: low overseas inventories, geopolitical disruptions and hawkish Federal Reserve policies on the overseas front, versus high domestic inventories, weak real demand and stable growth expectations domestically. This drove pronounced market divergence. Affected by intertwined internal and external factors, the main Shanghai aluminum contract corrected downwards from highs, while LME aluminum remained in a firm trading range, backed by historically low inventories, a tight spot balance and geopolitical risk premiums.

In April, the global aluminum market exhibited a core pattern of LME outperforming SHFE with divergent trends. The most-traded SHFE aluminum contract fluctuated at highs before pulling back, while LME aluminum maintained strength supported by low inventory and geopolitical factors, with both experiencing slight corrections at month-end. This month's market-driving logic revolved around macro policies, geopolitical conflicts, supply and demand fundamentals, and inventory structure, with core indicator trends further highlighting the differences in supply-demand imbalances between aluminum markets in and outside China.

[SMM Tin Midday Commentary: With the U.S.-Iran Negotiations Entering the Final Countdown and the Risk of Shipping Blockades, Low Inventory Underpinned Tin Prices as They Fluctuated at Highs]

Since the beginning of this year, the spot treatment charge market for copper concentrates has shown an unprecedented and severe downward trend. The SMM Copper Concentrate Spot Index has fallen from -45 USD/dmt at the start of the year to near -70 USD/dmt, with the speed and magnitude of the decline being historically rare. A negative treatment charge means that when smelters purchase copper concentrates, they not only fail to receive traditional processing income from miners but instead must pay the sellers. Based on the current TC of -70 USD/dmt, the actual cost smelters pay sellers in the copper smelting process is equivalent to a TC of 70 USD, or further converted to a TC+RC of approximately 112 USD. This extreme price signal has quickly drawn high market attention to smelter profitability and even sparked concerns about the sustainability of domestic copper smelting production. Despite treatment charges falling to historic lows, copper cathode production by Chinese smelters remains at high levels, currently around 1.2 million tons per month. This phenomenon of "producing more while losing more" appears, on the surface, to contradict market logic, but actually reflects smelters' passive choices and structural supporting factors in the current complex environment. Historically, extreme treatment charge scenarios are not unprecedented. In past industry downturns, smelters often relied on one or several factors—exchange rate fluctuations, rising sulfuric acid prices, or treatment charges themselves—to barely maintain cash flow balance. In the current cycle, the sharp rise in sulfuric acid prices has become a key variable supporting smelter survival. Currently, the ex-factory prices of smelter acid sold by domestic copper smelters generally range from 800 to 1,600 yuan per ton. The latest SMM Copper Smelting Acid Index stands at 1,235.5 yuan/ton. As a crucial byproduct of copper smelting, sulfuric acid price fluctuations significantly impact smelters' comprehensive earnings. Typically, smelters produce approximately one ton of sulfuric acid for every dry metric ton of copper concentrate processed. Based on the current sulfuric acid price of 1,235.5 yuan/ton, after deducting value-added tax (at a 13% rate) and converting to US dollars (using an exchange rate of 6.9), each ton of sulfuric acid can contribute about 158 USD in revenue for the smelter, equivalent to an additional 158 USD per dry metric ton of copper concentrate. If further converted to the TC+RC metric, this amounts to about 99 USD. Thus, the rise in sulfuric acid prices has significantly offset the loss pressure from negative copper concentrate treatment charges, with some more efficient smelters even achieving marginal profitability. It is precisely this "stabilizer" role of sulfuric acid that allows smelters to maintain high operating rates under extreme treatment charge conditions. However, the support of sulfuric acid for smelting profits is not unlimited, as its price trend is itself influenced by more complex international geopolitical factors. The recent sharp escalation of the Middle East situation has brought significant uncertainty to the global sulfuric acid and sulfur supply chain. Since the joint US-Israeli military strike against Iran on February 28, 2026, the Strait of Hormuz, the world's most critical energy transport route, has rapidly fallen into a severe transit crisis. After taking office, Iran's new Supreme Leader, Mojtaba Khamenei, immediately declared that the strait would remain closed as a strategic lever against the US-Israeli alliance and suggested that neighboring countries close US military bases. The Islamic Revolutionary Guard Corps subsequently explicitly announced a ban on any vessels associated with the US or Israel from passing through the Strait of Hormuz, warning of severe consequences for unauthorized passage. The Strait of Hormuz is a critical chokepoint for global sulfur transport. Statistics show that before the conflict, over 100 ships passed through the strait daily. However, after the conflict erupted, transit traffic plummeted by over 90%, with extreme cases of no ships passing for an entire day, leaving over 3,000 vessels stranded in nearby waters. This effective blockade has not only directly impacted the crude oil market—with Brent crude futures rising over 50% within a month to exceed 114 USD per barrel—but has also severely disrupted the global supply chain for sulfur and sulfuric acid. War risks have caused shipping insurance costs to soar to over 20% of the cargo value, further increasing logistics costs and plunging global sulfur supply into a logistical crisis. Although Iran claims to allow passage for vessels from "non-hostile" countries, requiring them to obtain prior permission, actual transit volumes remain extremely low, far below global trade demand. Simultaneously, the Houthi armed group in Yemen has announced its involvement, posing new security threats to the Red Sea-Suez route. The compounding pressure on the two major shipping chokepoints of the Strait of Hormuz and the Red Sea is posing a systemic challenge to the global supply chains for energy and chemical raw materials. As the primary raw material for sulfuric acid production, the disruption in sulfur supply directly drives international and domestic sulfuric acid prices progressively higher. Given the current situation, geopolitical conflicts show no signs of easing in the short term, implying further room for sulfuric acid price increases. The continued rise in sulfuric acid prices will have a dual impact on the domestic copper smelting industry. On the one hand, increased sulfuric acid revenue will continue to provide crucial profit supplementation for smelters, enabling them to maintain production even at lower TC levels and potentially further depressing spot copper concentrate treatment charges. On the other hand, this surge in sulfuric acid prices, driven by geopolitical conflict, also makes smelter profitability highly dependent on external unstable factors, rendering the industry's overall risk resilience increasingly fragile. Notably, the extreme treatment charge environment has begun to have a tangible impact on the global layout of copper smelting capacity. Mitsubishi Materials of Japan recently announced its plan to cease operations at its Onahama copper smelter by the end of March 2027. The smelter has a crude and refined capacity of 230,000 tons, and the main reason for the closure is precisely the intensified competition in the global copper smelting industry, leading to a sharp deterioration in copper concentrate TC/RC and persistent pressure on business prospects. This decision sends a clear signal: against the backdrop of continuously bottoming treatment charges and industry profits highly dependent on byproducts and external environments, some high-cost smelting capacity or those lacking comprehensive recovery capabilities are facing pressure to exit the market. In summary, China's copper smelting industry is currently at a highly unusual cyclical juncture. On one hand, smelters, benefiting from high sulfuric acid prices, have temporarily weathered the impact of negative treatment charges, maintaining high output. On the other hand, sulfuric acid prices themselves are heavily dependent on geopolitical situations, and external variables like the Strait of Hormuz blockade introduce significant uncertainty into the sustainability of smelting profits. If tensions in the Middle East persist, sulfuric acid prices may continue to rise, leaving room for TC to fall further, potentially enhancing smelters' tolerance for extreme treatment charges in phases. However, if geopolitical tensions ease, sulfur supply chains recover, and sulfuric acid prices retreat from their highs, smelters would face the risk of a "double blow" from both low treatment charges and reduced byproduct revenue, potentially heralding a genuine phase of capacity reduction and deep adjustment for the industry. Therefore, the current apparent "resilience" of the copper smelting industry is essentially built upon a fragile balance between geopolitical factors and the byproduct market. For market participants, besides monitoring TC trends, it is crucial to closely track changes in sulfuric acid prices and the underlying geopolitical factors to make more accurate judgments regarding the production sustainability and profitability prospects of the smelting industry.
