The International Copper Study Group (ICSG) released preliminary data on global copper supply and demand for March 2026 in its monthly bulletin published in May 2026. Preliminary data indicated that global copper mine production in Q1 2026 was basically flat, with copper concentrates production declining by 1.1%, offset by a 3.3% increase in solvent extraction-electrodeposition (SX-EW) production. Although global mine production benefited from additional output driven by capacity ramp-up of projects in several countries, significant declines in copper concentrates production in Chile, the DRC, and Indonesia offset global growth. In Indonesia, copper concentrates production at the Grasberg mine fell by 42%, as the severe mud inflow incident that occurred in September last year continued to affect the mine's production. Chile's mine production declined by 5.8%, with increased production at the Collahuasi and Quebrada Blanca mines offset by production cuts at the Spence, El Teniente, Escondida, and Los Pelambres mines. The DRC's mine production is estimated to have grown by only 0.5%: SX-EW production increased by approximately 10%, but was partially offset by a 36% decline in copper concentrates production due to reduced output at the Kamoa mine (affected by the 2025 earthquake event). In Peru, copper mine production grew by 3.3%, primarily driven by increased production at the Antamina, Las Bambas, and Antapaccay mines, which more than offset production declines at Southern Peru Copper, Quellaveco, and Marcobre. Mongolia's copper concentrates production is estimated to have grown by approximately 36%, benefiting from the capacity ramp-up of the Oyu Tolgoi underground project. Preliminary data indicated that global copper cathode production grew by approximately 4.5% in Q1 2026, with primary copper (electrolysis and ore electrodeposition) production increasing by 3.8% and secondary copper (from scrap) production increasing by 7.6%. China and the DRC, which currently account for approximately 60% of global production, saw their combined production increase by an estimated 9% (China 8.8%, DRC 10%). Excluding these two countries, global copper cathode production declined by approximately 1.4%. Chile's copper cathode production fell by 11.7%, with copper cathode (from concentrates) production declining by 24% due to smelter operational constraints and maintenance, and electrodeposition copper production declining by 5.7%. Production in Asia (excluding China) is estimated to have declined by 4%, mainly due to production decreases in Japan, Indonesia, and the Philippines. India's production is estimated to have grown by 25%, benefiting from improved capacity utilization rates and the capacity ramp-up of the Adani smelter. Global secondary refined copper production (from scrap) increased by 7.6%, mainly driven by growth in China. Preliminary data indicated that global apparent refined copper usage grew by 0.8% in Q1 2026. Although global usage excluding China was estimated to have grown by 1.7%, China's apparent demand (excluding bonded warehouse/unreported inventory changes) was estimated to be basically flat, affected by a 40% decline in China's net imports of copper cathode. China currently accounts for approximately 58% of total global refined copper usage. The preliminary global refined copper supply-demand balance indicated an oversupply of 396,000 mt in Q1 2026. In compiling the global market balance, ICSG used China's apparent demand calculation method, which does not account for changes in unreported inventories. However, to facilitate global market analysis, an adjustment item has been added to the attached tables — "Global refined copper balance adjusted for Chinese bonded warehouse inventory changes" — which adjusts the global refined copper balance based on the average bonded warehouse inventory change estimates from two Chinese copper market consultancies. In Q1 2026, the global refined copper balance based on China's apparent usage (excluding bonded warehouse/unreported inventory changes) showed a preliminary oversupply of approximately 396,000 mt, compared with an oversupply of approximately 135,000 mt in the same period of 2025. The global refined copper balance adjusted for estimated changes in Chinese bonded warehouse inventories showed a market oversupply of approximately 386,000 mt. Copper Prices and Inventories: Based on the average estimates from two independent consultancies, Chinese bonded warehouse inventories were estimated to have decreased by approximately 10,000 mt from the end of 2025 levels during the first three months of 2026. As of the end of April 2026, copper inventories at major metal exchanges (LME, COMEX, SHFE) totaled 1,148,760 mt, the highest level since January 2003. Inventories increased by 404,648 mt, or 55%, from the end of December 2025, with LME up 253,350 mt, Shanghai Futures Exchange up 46,683 mt, and COMEX up 104,615 mt. The LME spot copper average price in April was $12,891.38 per mt, up 3% from the March average price of $12,498.98 per mt. The 2026 copper price high and low were $14,097 per mt (May 13) and $11,826 per mt (March 19), respectively, with a year-to-date average price of $12,947.22 per mt, up 30% from the 2025 average price.

SMM, May 22: The most-traded SHFE lead 2607 contract opened at 16,700 yuan/mt. During the session, SHFE lead prices fluctuated at highs within a narrow range around the daily moving average, touching a high of 16,770 yuan/mt in the later session, recording a three-day winning streak, up 90 yuan/mt, a gain of 0.54%. This week, regional inventory performance diverged. Smelters in east China delayed shipments and retained stock due to weakening lead prices, while finished product inventories in other regions edged down, and overall industry inventory increased slightly. After delivery completion, lead ingot social inventory pulled back slowly, with a weak degree of destocking. As multiple smelters resumed production, secondary lead output edged up, constraining price increases. On the capital front, bears reducing positions drove the market to recover, and lead prices were expected to move sideways in the short term with a fluctuating trend. Data source statement: Data other than public information is derived from public information, market communication, and SMM's internal database models, processed by SMM for reference only and does not constitute decision-making advice.

SMM May 22 update: SHFE lead fluctuated with initial weakness followed by strength this week, and secondary refined lead quotes continuously switched between premiums and discounts following futures fluctuations. At the beginning of the week, lead prices declined, but smelter quotes remained relatively firm, mainly hovering around parity to slight premiums, with very few market transactions. Mid-week, futures consolidated on the weak side, and smelters held prices firm for shipments, with quotes stable at parity to a premium of 50 yuan/mt, with only rigid demand making sporadic purchases. Later in the week, lead prices rebounded, smelter shipment sentiment diverged, and quotes gradually shifted to discounts of 0-50 yuan/mt, with some still retaining slight premiums. Downstream players mostly digested inventories after restocking on dips earlier, purchase willingness cooled, and overall spot transactions remained sluggish throughout the week. SMM #1 lead ingot spot prices were initially weak then strengthened this week, but downstream battery plants maintained strong wait-and-see sentiment, spot transactions were poor, and smelter loss pressure further expanded. As of May 14, large enterprises posted losses of 290 yuan/mt, and small and medium-sized enterprises posted losses of 496 yuan/mt. As scrap battery raw material inventory pulled back WoW this week, smelter restocking expectations warmed up, and cost-side upward expectations strengthened. Smelting profits are expected to remain under pressure next week, with the loss pattern continuing. In addition, some smelters plan to resume production next week, secondary refined lead supply is set to increase, and spot premiums are expected to converge.

Next Monday, the LME will be closed for one day due to the Spring Bank Holiday, while the NYSE and CME will also be closed for holidays, and Malaysia will have a one-day holiday on May 27 for Hari Raya Haji. On the macroeconomic data front, key releases are about to be published, including the US April core PCE price index year-on-year rate, the revised US Q1 real GDP annualized quarter-on-quarter rate, and the US April personal spending month-on-month rate. Additionally, the US and Russian presidents visited China successively recently, improving expectations for dialogue and cooperation among major powers, and easing market risk-aversion sentiment. LME lead side, ex-China LME lead inventory unexpectedly surged by over 20,000 mt this week, but LME lead Cash-3M backwardation rose to $22.55/mt, with the trend diverging from inventory. The tight supply of high-grade lead ingots in the Southeast Asian market has not yet eased, while Australian lead-zinc smelters are ramping up production. With both bullish and bearish factors coexisting in the market, lead prices are expected to continue to fluctuate at highs. LME lead is expected to trade in the range of $1,970-2,030/mt next week. SHFE lead side, the recent decline in lead prices brought some downstream buy-the-dip stocking demand, and combined with reduced lead imports, this contributed to lead ingot destocking and supported lead prices to rebound after probing lows. Meanwhile, secondary lead enterprises are gradually resuming production, and secondary refined lead transaction prices have shifted to a discount (against the SMM #1 lead average price). The incremental supply is putting pressure on the sustainability of subsequent lead ingot destocking, limiting upside room for lead prices. The most-traded SHFE lead contract is expected to trade in the range of 16,500-16,850 yuan/mt next week. Spot price forecast: 16,400-16,650 yuan/mt. Consumption side, the lead-acid battery market remains in an off-season pattern, with downstream enterprises' rigid demand still limited. Combined with the rebound in lead prices, downstream enterprises have become more cautious in procurement. Supply side, production at both primary lead and secondary lead enterprises is stable to slightly higher. Among them, secondary lead losses have begun to narrow, market circulating supply has increased, and the probability of spot lead transactions shifting to a discount is growing (against SMM #1 lead).

As of May 21, the in-factory inventory of major primary lead delivery brands stood at 13,400 mt, down 9,900 mt WoW. In the first half of the week, lead prices weakened, with spot lead falling below 16,300 yuan/mt. Losses for secondary lead deepened, and secondary lead smelters became less willing to ship, with some even temporarily suspending shipments. Meanwhile, as lead prices declined, downstream enterprises gradually bought the dip, with procurement tilting toward the primary lead segment, driving down in-factory inventory at primary lead smelters.
