SHANGHAI, May 23 (SMM) – LME and SHFE base metals closed mostly with losses overnight on macro headwinds from the US. On the macro front, the market is waiting for new data to find signs of whether the Fed may continue to raise interest rates. The hawkish speech of Fed officials made the market more worried. At the same time, attention should be paid to the debt ceiling issue. The US index fluctuated higher on Monday.

Copper: LME copper prices closed at $8,144/mt overnight, a decline of 1.21%. Trading volume was 15,000 lots and open interest stood at 256,000 lots. SHFE 2307 copper contract finished at 64,770 yuan/mt overnight, down 0.52%. Trading volume was 37,000 lots, and open interest stood at 185,000 lots. On the macro front, the market is waiting for new data to find signs of whether the Fed may continue to raise interest rates. The hawkish speech of Fed officials made the market more worried. At the same time, attention should be paid to the debt ceiling issue. The US index fluctuated higher on Monday. As of Monday May 22, SMM copper inventory across major Chinese markets stood at 122,700 mt, down 800 mt from last Friday but up 12,900 mt from the same period last year. Spot premiums in east China were high last Friday, and shipments arrivals of both imported and domestic copper increased. This drove up inventories in Shanghai and Jiangsu. In Guangdong, shipments arrivals decreased over the weekend while shipments leaving Guangdong increased, significantly reducing local inventories. In terms of consumption, downstream demand is more sensitive to changes in copper prices, and overall consumption is in a relatively weak. Most market participants are bearish and domestic demand is weak. It is expected that copper prices will remain low in the short term.

Aluminium: The most-traded SHFE 2306 aluminium contract opened at 18,220 yuan/mt overnight, with its low and high at 18,110 yuan/mt and 18,250 yuan/mt before closing at 18,230 yuan/mt, up 40 yuan/mt or 0.22%. LME aluminium opened at $2,288/mt on Monday, with its low and high at $2,249.5/mt and $2,289.5/mt respectively before closing at $2,263.5/mt, a drop of $20.5/mt or 0.9%.

On the macro level, the US debt ceiling negotiations have failed to reach an agreement for now, adding to macro uncertainty. End-user consumption is still recovering, but aluminium supply remains in a surplus. Falling prebaked anode and coal prices weakened cost support to aluminium prices. Macro headwinds and poor fundamentals will expose the short-term aluminium prices to downside risks.

Lead: Overnight, LME Lead opened at $2,097/mt and closed at $2,093/mt after hitting the highest point at $2,097/mt and the lowest point at $2,077/mt, up 0.1%.

The most-traded SHFE 2306 lead contract opened at 15,355 yuan/mt and closed at 15,315 yuan/mt after hitting the highest point at 15,370 yuan mt and the lowest point at 15,270 yuan/mt, down 0.45%.

Zinc: LME zinc went down after opening at $2,476.5/mt on Monday, closing at $2,425.5/mt, down $51/mt or 2.06%. Trading volume added 8,013 lots to 1,682 lots, and open interest rose 423 lots to 183,000 lots. LME zinc inventory decreased by 700 mt to 46,275 mt, a drop of 1.19%. The US index hovered at a two-month high, sending LME zinc down.

Overnight, the most-traded SHFE 2307 zinc contract opened at 20,265 yuan/mt. The contract rose at first and then fell back before closing at 20,170 yuan/mt, down 2,155 yuan/mt or 1.05%. Trading volume fell 35,622 lots to 67,485 lots, and open interest rose 3,138 lots to 123,000 lots. SHFE zinc met resistance at the 5-day moving average. Downstream consumption is not strong.
Tin: Yesterday night, SHFE 2306 tin contract prices dipped slightly after opening and stabilized at 195,610 yuan/mt, and finally closed at 196,210 yuan/mt, down 1.63%.

In the spot market, small and medium-sized enterprise sold at discounts of 500-300 yuan/mt and the deliverable brands mainly sold at 100-500 yuan/mt. However, the transactions did not change much. Although the price drop boosted the spot transactions, the active procurement in the previous stage limited the improvement.

Nickel: On the supply side, NORNICKEL nickel premiums grew yesterday on active market trades and shrinking supply. NPI prices offered by stainless steel mills generally stood at or below 1,120 yuan/mtu (delivery to factory), while the prices quoted by domestic NPI plants remained firm. On the demand side, according to SMM research, stainless steel futures prices crashed following overseas futures prices. However, the spot prices were firm yesterday. A stainless steel plant in east China announced that it would reduce the shipments of cold-rolled coils to the market and would continue to control the hot-rolled coil shipments. Another stainless steel mill in east China announced the closure of long-shaped product deals at noon. Since there is no obvious accumulation of social inventory, the market players are cautious about shipping and quoting. Short-term stainless steel spot prices will fall. It is expected that nickel prices will gain some support from the low market inventory in the near term.

China's Refined Copper Output Growth Expected to Slow Sharply in 2026 Amid Feedstock Constraints
China's refined copper production growth is expected to slow sharply in 2026 as smelters face tightening copper concentrate and scrap availability alongside weaker sulphuric acid prices, according to foreign media reports. Wood Mackenzie and Zijin Tianfeng Futures expect China's refined copper output to increase by around 3–3.4% in 2026, compared with growth of 10.4% in 2025. Reuters said this would represent the slowest annual growth rate since at least 2000 based on its review of official production data. Refined copper output growth stood at approximately 4% year on year during January-August.​ The slowdown is expected to become more pronounced in the fourth quarter as tighter scrap copper supply adds to the existing shortage of copper concentrate. Reuters reported that a tax crackdown is expected to reduce scrap availability, further limiting smelters' ability to substitute secondary raw materials for concentrate when feedstock conditions tighten.​ Smelter economics have also come under pressure from lower sulphuric acid prices. Sulphuric acid, a major by-product of copper smelting, had previously helped offset extremely low copper concentrate treatment charges. According to Oilchem data cited by Reuters, Chinese sulphuric acid prices declined by around 11% during September.​ Seven Chinese copper smelters are reportedly planning equipment maintenance lasting between 30 and 60 days during October and November. Analysts at Zhuochuang estimate that the planned maintenance could reduce refined copper supply by approximately 80,000 mt.​ The concentrate shortage reflects a broader imbalance between rapidly expanding global smelting capacity and comparatively slower growth in mined copper supply. Recent temporary disruptions at major copper mines including Escondida, Las Bambas and El Teniente have added further pressure to concentrate availability.​ Slower refined copper production growth in China could reduce refined copper supply growth during the fourth quarter, particularly if planned smelter maintenance coincides with continued constraints in concentrate and scrap availability. The simultaneous decline in sulphuric acid prices is also weakening an important source of smelter revenue at a time when treatment charges remain under pressure. Attention will therefore remain on concentrate availability, scrap supply conditions and the scale of planned smelter maintenance during October and November.

Eldorado Gold Completes Skouries Grid Energization Ahead of Q4 Commercial Production
Eldorado Gold has completed the permanent grid connection and energization of its Skouries copper-gold mine in northern Greece, marking another key commissioning milestone as the project advances toward commercial production expected in the fourth quarter of 2026. The site was successfully energized following final inspection, testing and approval by the Greek transmission authority. Eldorado said the permanent connection to the national grid provides the long-term power infrastructure required to support continued commissioning and ramp-up of processing and mining systems across the operation. The milestone follows the recent achievement of first copper-gold concentrate production at Skouries on September 8. The company is now progressing commissioning and ramp-up activities as it moves toward steady-state operations and commercial production later this year. Skouries is a copper-gold operation being developed using a combination of conventional open-pit and underground mining methods. Based on the company's current mine plan, the operation is expected to produce an average of approximately 67 million lb, or around 30,400 mt, of copper per year over its mine life, alongside approximately 140,000 oz/year of gold. The permanent grid connection is particularly important for the operation of major process systems, including crushing, grinding, flotation, concentrate handling and tailings disposal, which require full site energization as commissioning advances. Completion of permanent grid energization removes an important infrastructure constraint at Skouries and supports the continued ramp-up of the project following first concentrate production earlier in September. With commercial production still targeted for Q4 2026, attention will now turn to the pace of commissioning and the transition toward steady-state operations. Once fully ramped up, Skouries is expected to become a meaningful new source of European copper supply, with average annual copper production of approximately 30,400 mt over the mine life.

Centinela Copper Mine Workers Approve Strike as Labour Talks Move to Mediation
Workers represented by two unions at Antofagasta Minerals' Centinela copper mine in northern Chile have voted overwhelmingly in favour of strike action after rejecting the company's latest collective bargaining offer. According to foreign media reports, 98.73% of union members voted in favour of a strike, with all eligible members participating in the vote. The Minera Esperanza and Distrito Centinela unions had previously urged their members to reject the company's proposal amid disagreements over employee benefits. The unions have argued that Antofagasta Minerals has declined to discuss equalising benefits for workers regardless of their union affiliation. Antofagasta Minerals does not comment on its ongoing collective bargaining negotiations. Despite the vote, a strike has not yet begun. The company and unions must now enter a mandatory five-day government-led mediation process before workers can legally begin strike action. The mediation period can be extended by another five days if both sides agree. Centinela is a major copper operation in Chile and produced 240,400 mt of copper in 2025. The outcome of the mediation process will therefore be closely watched for any potential impact on operations and copper supply. The 98.73% vote in favour of strike action represents an escalation in the labour negotiations at Centinela, but there has been no reported disruption to copper production at this stage. The mandatory mediation period provides an opportunity for the company and unions to reach an agreement before industrial action begins. Given Centinela's 2025 copper production of 240,400 mt, an extended work stoppage could create additional supply uncertainty, although the scale of any potential production impact cannot be estimated unless a strike begins and its duration becomes clearer.
