[Macro Policy and Tug-of-War Between Sellers and Buyers: Aluminum Prices Move Sideways] The risk of supply disruptions to aluminum outside China has not yet subsided, and there remains a supply gap in ex-China aluminum, with the strong LME market transmitting to China and providing support for aluminum prices. However, the continuation of inventory buildup exceeding expectations in China will weigh on domestic aluminum prices. Meanwhile, tightened invoicing regulations may lead to structural tightness in spot cargo, and the weakening spot market further limits the upside room for domestic aluminum prices. Close attention should be paid to the potential turning point in China's social inventory, which could drive a rebound and rise in aluminum prices.

At the 2026 SMM (3rd) Global Renewable Metal Industry Chain Summit & Battery Recycling Forum, Aw Yong Yi Cheong, SMM secondary copper analyst Shared insight on Japan's secondary copper market.He noted that, according to SMM, Japan's copper scrap market is gradually transitioning toward a fiercely competitive "seller ecosystem." Trade models that rely solely on spot cargo procurement are increasingly exposed to the risk of supply disruptions. To secure long-term resource supply， scrap buyers need to move beyond the traditional spot trading mindset and establish structural partnerships through deep-binding approaches such as signing long-term contracts and equity cooperation, in order to adapt to the persistently tight market landscape. Global Positioning of Japan's Copper Scrap Market Global Positioning of Japan's Copper Scrap Market Key Drivers Behind Japan's Leading Position in Asia 1 Precision Sorting: Exceptional classification accuracy ensures high-quality scrap output. 2 Well-Established Infrastructure: A mature "urban mine" system and advanced logistics provide a highly reliable supply foundation. 3 Strategic Geographical Advantage: Proximity to China (accelerating capital turnover), while serving as a key trans-Pacific logistics hub connecting the Americas and Asia. 4 Favorable Trade and Tax Policies: Zero export tariffs and transparent regulations ensure seamless global operations. 5 Commercial Reliability: High standards of packaging and business ethics minimize quality claims. Japan's Average Unit Price of Copper Scrap Significantly Leads the Top Five Global Exporters In 2025, Japan and Thailand each accounted for approximately 7% of global copper scrap exports. However, Japan commanded the highest average export price among major peers ($8,112/mt), thanks to a substantial quality premium. This price spread revealed fundamental differences in product mix. Thailand primarily served as a processing hub, with limited high-grade copper scrap output domestically. In contrast, Japan was organically driven by its mature "urban mine" ecosystem, consistently producing high-purity, high-grade materials. Flow of Japan's Copper Scrap Flow of Japan's Copper Scrap Rising Trade Volume and Shrinking Net Exports: A Shift Toward Domestic Retention Smelters Drove Copper Scrap Consumption Growth While Downstream Processing Enterprises Saw Declining Usage compared with 2021, processing enterprises' copper scrap usage declined by 8% in 2025. Processing enterprises: Weak downstream demand (automotive, construction) and fierce global competition for high-quality copper scrap severely squeezed domestic processing enterprises, resulting in a sustained 8% decline in their absolute usage. Smelters: Tightened environmental protection and export policies implemented since 2023 restricted the outflow of copper scrap, significantly accelerating this structural "reflux" toward smelters. Combined with the plunge in TC/RC, Japanese smelters were forced to rely on these raw materials to maintain production. Consequently, the share of copper scrap consumed by the smelting segment has maintained an overall upward trend in recent years. Japan's overall scrap supply is contracting; despite robust growth in domestic consumption, the structural decline in net exports is the primary driver. Since the 2021 peak, Japan's total apparent supply of copper scrap has been on an overall downward trend. This indicates structural tightening in domestic scrap generation and social recovery rates, with increasingly scarce available resources. Despite the overall supply contraction, domestic apparent consumption demonstrated strong resilience, as Japanese smelters actively secured local raw materials to maintain production amid plunging TC. This robust local demand is significantly squeezing exports. Net exports have consequently declined structurally to low levels. Japan is shifting from a "resource overflow" model to an "internal absorption" model, which will severely exacerbate raw material shortages for Southeast Asian and Chinese buyers. Millberry payability stays high: supply tightness and China's tax-driven demand outweigh the impact of recent copper price rebound Since early 2026, market copper prices have risen steadily overall; in March, copper prices experienced a periodic pullback, and copper scrap sellers held prices firm with strong willingness to defend price floors, directly driving the bare bright copper payable indicator passively higher. Entering April, futures copper prices rebounded and stabilized at highs, but the copper scrap payment ratio deviated from conventional pricing logic and did not pull back accordingly, remaining firmly in the 98.5%-99.0% range. The core supporting logic lies in: continued tightening of domestic tax regulation, with China's downstream processing enterprises increasingly relying on imported copper scrap to obtain compliant input tax deductions, forming rigid procurement demand; coupled with tight spot copper scrap supply, the dual support of supply and demand underpins the copper scrap payment ratio to stay high. Japan's Scrap Policies Japan's Scrap Policies Regulatory Shift: Building an "Invisible Wall" Although Japan has not explicitly imposed export bans, it strengthens its domestic closed-loop system through a strategic policy combination. For global buyers, this signals a structural shift in the Japanese market going forward: intensified competition, soaring procurement costs, and increasing difficulty in accessing high-quality scrap. Regulatory maturity and standardized transparency are the primary drivers of the "Japan premium." Policy Lag vs. Market Reality: Although the EU Waste Shipment Regulation and potential US export restrictions have not yet been formally enacted, the market has already priced in expectations of future supply contraction, compelling downstream buyers to proactively pivot toward trade hubs with higher compliance and transparency. "Reliability Premium" Logic Emerges: As a pioneer in industry compliance and market transparency, Japan can effectively hedge against risks prevalent in other regions, such as insufficient information transparency and origin rerouting, providing the market with an important safe-haven and pricing anchor function. Outlook and Forecast Strategic Outlook and Forecast Driven by aggressive development targets at both enterprise and national levels, scrap consumption by domestic smelters in Japan is set to experience significant structural growth. According to SMM, the climb in scrap consumption by Japanese smelters is not a short-term cyclical response triggered by declining mine TCs, but rather a fundamental structural transformation underpinned by strong capital strength and long-term commitment. As 2030 ESG-related targets continue to materialize, the trend of retaining domestic scrap for internal use in Japan will deepen further, structurally tightening global circulating scrap supply over the long term and continuously compressing the available sourcing volume for ex-China buyers. Response Logic for the "New Normal" in Japan's Copper Scrap Market Volume and Flow Direction: Steady Decline Net exports of copper scrap will not plunge to zero abruptly, but rather exhibit a sustained structural decline trend. As domestically subsidized capacity comes fully online, exports of high-grade secondary copper such as bare bright copper and No.1 copper will enter a steady contraction trajectory. Pricing Logic: The traditional medium and long-term linkage of "rising copper prices, declining scrap payment ratios" has been structurally reshaped. Under the dual effects of persistently tight copper concentrates supply and China's rigid tax-driven procurement demand providing a floor, the payment ratio for Japan's high-quality copper scrap is expected to establish a long-term upward baseline. Strategic Pivot: Constrained by the upper limit of domestic secondary copper output and tight labor supply, Japanese recycling industry alliances will accelerate their expansion into markets outside China. Japanese enterprises will invest in overseas joint venture projects to solidify downstream processing capacity deployment while maintaining Japanese-led control over raw material supply chains. According to SMM analysis, the current Japanese copper scrap market is gradually transitioning toward a fiercely competitive "seller ecosystem." Trade models that rely solely on spot purchases are increasingly exposed to the risk of supply disruptions. To secure long-term resource supply, ex-China purchasing enterprises need to move beyond the traditional spot trading mindset and establish structural partnerships through deep-binding approaches such as signing long-term contracts and equity cooperation, thereby adapting to the persistently tight market landscape.

Driven by recovering risk appetite and China's peak demand season, copper prices both in China and abroad bottomed out since late March. However, as SHFE copper returned to the 100,000 level, the tug-of-war between longs and shorts increased, and futures prices shifted to range-bound consolidation. After the Labour Day holiday, copper prices quickly resumed their upward momentum. Today, prices opened higher with a gap and continued to rise, with SHFE copper just one step away from the record high set at the end of January, while LME copper hit a new closing high. What is fueling such strong confidence behind this rally? Deepening Ore-Side Vulnerability Intensifies Supply Disruption Concerns Since the suspension of First Quantum's Cobre Panama copper mine at the end of 2023, spot TC for copper concentrates in China has been caught in an endless downward spiral. Falling from around $80/dmt at the end of 2023, it largely dropped to single-digit levels and moved sideways in 2024. Entering 2025, it further plunged into negative territory, mainly due to successive production disruptions at world-class copper mines including Ivanhoe Mines' Kakula, Codelco's El Teniente, and Freeport's Grasberg mine in Indonesia. Entering 2026, global major copper ore supply growth remained limited, and the ore tightness showed no improvement. The latest data showed that spot TC for copper concentrates in China had fallen below -$90/dmt. With long-term contract TC at zero and spot TC declines accelerating, domestic smelters' production profits mainly relied on surging sulphuric acid prices and firm by-product prices of gold, silver, and other metals to compensate. It was reported that current sulphuric acid revenue could already cover smelters' procurement costs for copper concentrates and part of the processing costs, enabling domestic smelters to maintain relatively high operating rates, and the ore tightness had not yet notably transmitted to the smelting side. It is worth noting that sulphuric acid is not only a by-product of pyrometallurgy but also a core production material for SX-EW copper. For every 1 mt of copper produced, 5–6 mt of sulphuric acid is consumed. Sulphuric acid costs account for 40%–50% of total SX-EW copper production costs, and SX-EW copper production accounts for approximately 20% of global mine copper production. Since the beginning of this year, sulphuric acid prices surged sharply due to multiple factors, and ex-China sulphuric acid supply was periodically disrupted, raising concerns that copper supply in some countries could be affected. Focusing on the reasons behind the sulphuric acid price surge: on one hand, since the escalation of the Middle East conflict on February 28, shipping through the Strait of Hormuz has been broadly restricted and has recently faced a dual blockade by Iran and the US. Sulphur exports from the Middle East have been impacted, with the DRC and Zambia being the most concentrated SX-EW copper producing regions that are highly dependent on sulphur imports from the Middle East. As sulphur supply has been constrained, sulphuric acid prices have naturally risen in tandem, not only raising local SX-EW copper production costs but also potentially triggering further production cuts if the Strait of Hormuz blockade continues and sulphur disruption risks escalate. On the other hand, to prioritise domestic spring ploughing phosphate fertiliser production and support new energy industry expansion, China has imposed a phased ban on sulphuric acid exports according to industry sources. Chile has a relatively high dependence on Chinese sulphuric acid, with SX-EW copper accounting for around 20% of its output, and the market is also concerned that Chile's SX-EW copper production may be affected. In addition, against the backdrop of an already fragile copper ore supply, frequent news shocks from outside China recently have undoubtedly intensified market concerns. Last week, market rumours suggested that the full restart of Indonesia's Grasberg copper-gold mine, which declared force majeure in September last year, had been delayed by one year, driving SHFE copper sharply higher in the afternoon of 8 May. However, according to the latest update from Freeport-McMoRan, the company still expects Indonesia's Grasberg copper-gold mine to fully resume production by the end of 2027, reaffirming the plan outlined last month and refuting reports that production resumptions could be delayed to 2028. Furthermore, yesterday Peru declared an emergency energy decree due to a natural gas pipeline explosion. Peru's copper production reached 2.63 million mt in metal content last year, ranking third globally. Copper mining and smelting are relatively sensitive to power stability, and the market is concerned that Peru's energy strain may disrupt local copper supply. Overall, China's copper cathode production remains relatively stable, but some major global miners lowered their full-year production guidance in Q1, the ore tightness persists, sulphuric acid supply — a core raw material for ex-China SX-EW copper — is constrained, and there are multiple supply disruption themes on the copper supply side, which can easily boost copper prices once the macro front stabilises. Global Copper Visible Inventory Divergence: China Destocking Provides Support Last year, driven by the US government's threat to impose additional tariffs on imported copper, global copper continued to flow into the US, causing COMEX copper inventories to accumulate continuously while copper inventories in non-US regions remained low, providing sustained support for copper prices. In February this year, the US Supreme Court struck down most of the tariff measures introduced by the Trump administration in 2025. The Trump administration subsequently turned to Section 122 of the Trade Act of 1974 to push new global tariff policies. On 7 May, the US Court of International Trade issued a ruling stating that the legal basis for imposing a 10% global import tariff was invalid. The tug-of-war between US courts and the Trump administration over tariffs has continued recently, but the market has certain expectations that the US may subsequently impose additional tariffs on imported copper. Under such expectations, the price spread between COMEX copper and LME copper has shown a slight strengthening trend recently, meaning copper in LME warehouses still has the potential to flow to the US. Specifically, COMEX copper inventories have continued to rebound since mid-April, rising from around 590,000 mt to the latest 620,000 mt, again hitting a multi-year high. Correspondingly, LME copper inventories pulled back from around 400,000 mt in mid-April, declining to 397,700 mt on 6 May. They have rebounded with fluctuations recently, but overall inventories have not exceeded the over-12-year high set in mid-April. SHFE copper inventories fell for the eighth consecutive week, currently dropping to 181,300 mt, the lowest since the beginning of the year. Data source: Webstock Inc. Overall, on the macro front, there are currently disagreements in US-Iran negotiations, but both sides continue the ceasefire with no recent signs of escalation in conflict. Energy prices pulled back from late April levels, inflation concerns eased somewhat, the US dollar index was in the doldrums, and combined with the AI boom lifting global stock markets, market risk appetite was moderate, providing a fertile ground for copper prices to strengthen. Focusing on copper's own fundamentals, inventories outside China remained elevated, but significant prior destocking of China inventories provided support. The ore tightness was difficult to reverse, and supply-side narratives were abundant, meaning copper prices may still hold up well. However, it is worth noting that the Middle East situation remains the biggest macro variable, and the policy path following the Fed Chairman's power transition also deserves close attention.

Today, the most-traded BC copper 2606 contract opened at 93,550 yuan/mt, touching a low of 93,550 yuan/mt right at the open before maintaining a fluctuating trend at highs. Near the close, it rose to 95,490 yuan/mt and ultimately settled at 94,500 yuan/mt, up 1.81%. Open interest stood at 9,614 lots, an increase of 82 lots from the previous trading day, while trading volume reached 10,260 lots, an increase of 1,881 lots from the previous trading day. On the macro front, Peru, as a major global copper exporter, issued an emergency energy crisis decree on Monday, sparking market concerns over ore supply disruptions and driving copper prices to fluctuate at highs. Fundamentals side, on the supply side, with delivery approaching, suppliers showed a stronger willingness to ship to delivery warehouses, and the spot supply landscape remained tight; on the demand side, downstream purchasing sentiment was weak due to high copper prices. The SHFE copper 2606 contract closed at 106,510 yuan/mt. Based on the BC copper 2606 contract price of 94,500 yuan/mt, its after-tax price was 106,785 yuan/mt. The price spread between the SHFE copper 2606 contract and BC copper was -275 yuan/mt, showing an inversion that widened compared to the previous day.

[SMM Shanghai Spot Copper] Looking ahead to tomorrow, Peru's energy crisis has raised market concerns over copper ore supply. Copper prices surged significantly during the night session, and end-users' acceptance of the current high copper prices and spot discounts has declined. According to SMM, downstream orders dropped sharply during the day, with purchasing sentiment subdued and dominated by rigid demand. In terms of market performance, suppliers continuously lowered their offers, and spot cargo has shifted from premiums to discounts, with the discount margin widening. However, Friday marks the last trading day of the SHFE copper 2605 contract. As delivery approaches, spot discounts are widening under the Contango price spread structure, and suppliers' willingness to ship to delivery warehouses is increasing. The delivery logic is expected to provide bottom support for spot discounts, limiting further downside room.
