High copper prices, ample supply, weak demand, inventory buildup, weak structure ↓ Falling copper prices, still ample supply, good demand, destocking, slightly stronger structure ↓ Fluctuating copper prices, relatively tight supply, demand fluctuating with copper prices, high probability of destocking, high probability of strengthening structure Q1 2026 has ended, and April trading days are also about to end. The above two sentences summarize SHFE copper futures and spot market performance. Note that this refers only to copper cathode supply, as China saw significant production increases in 2025. Despite continued ore tightness, production in 2026 has also remained fluctuating at highs, keeping copper cathode supply persistently ample. Demand side, although annual demand showed growth, when broken down to monthly or even daily levels, demand was significantly influenced by copper prices. Amid copper price fluctuations, secondary copper was the "active player" — when copper prices were high, secondary copper shipments increased, benefiting both supply and demand sides; when copper prices fell, secondary copper shipments decreased, reducing some raw material supply for both supply and demand. So recently the spot market appeared to have tight supply. Smelters began shifting to "high prices with high volumes" in shipments. Against the backdrop of continued destocking and concentrated smelter maintenance, can premiums "heat up"? The chart above shows that from a macro perspective, copper prices and Shanghai spot copper premiums exhibited a clear inverse correlation in recent years. However, from a detailed perspective, Shanghai spot copper premiums have recently shown signs of "picking up" under high copper prices. 1. Although inventory continued destocking, the current warrant-to-inventory ratio remained elevated (this indicator is highly correlated with structure). The SHFE copper near-month structure has not shown a sustained backwardation structure to provide guidance for future premiums. 2. Although copper prices returned to highs, overall secondary copper shipment sentiment remained subdued, providing limited supplementation to copper cathode production and consumption. Previously, the price difference between primary metal and scrap was inverted, which favored copper cathode consumption. During this process, non-registered supply supplementation was limited, and the price spread between non-registered and SX-EW copper also narrowed. Imported copper supplementation within the year decreased YoY compared to previous years. Taking DRC as an example, non-registered supply was also diverted. Overall, substitutes for registered copper cathode decreased. 3. Copper cathode supply itself is about to decrease in the coming months, with concentrated maintenance currently underway in the market. Social inventory is expected to further decline. As inventory decreases and the warrant-to-inventory ratio declines, the far-month structure has already shifted to backwardation. China's spot premiums are also expected to pick up in the near term. It has been observed that Guangdong spot premiums have been consistently higher than other regions nationwide for several consecutive days. Downstream buyers in Jiangsu, Zhejiang, Shanghai, and Anhui have recently tended to purchase from direct producers and traders with inventory who can issue invoices for the current month. Shanghai spot copper premiums are expected to see a small spike before the Labour Day holiday. After the holiday, as domestic supply decreases, premiums are expected to gradually firm up. However, the warrant-to-inventory ratio remains relatively high, and a sustained shift to backwardation in the structure still requires patience.

On Tuesday, April 28, the International Copper Study Group (ICSG) stated in its latest monthly bulletin that the global copper cathode market posted an oversupply of 276,000 mt in February, compared with a surplus of 34,000 mt in January. Data showed that global copper cathode production totaled 2.26 million mt in February, while consumption stood at 1.98 million mt. The organization also added that for the first two months of 2026, based on China's apparent consumption (excluding bonded warehouse and unreported inventory changes), the global copper cathode supply and demand preliminarily indicated an oversupply of approximately 310,000 mt.

Recently, the center of copper prices continued to shift upward. The most-traded SHFE copper contract steadily climbed after hitting a periodic low of 91,500 yuan/mt on March 23, 2026, reaching a high of 103,130 yuan/mt as of April 15, representing a gain of 12.71% from low to high, with the latest closing price at 102,090 yuan/mt. The latest LME copper price stood at $13,262.5/mt. The interaction between macro sentiment and fundamentals jointly drove the market to hold up well. This round of copper price strength was not dominated by a single factor, but rather the result of a resonance of multiple factors including geopolitical conflicts, supply constraints, inventory changes, and seasonal consumption patterns. Regarding the core driving logic behind the current copper price strength, SMM will provide a detailed analysis from three dimensions: the contraction of SX-EW copper supply outside China, the macro perspective on the US dollar and geopolitical developments, and China's copper inventories and supply-demand pattern. The details are as follows: （I) Sulphuric Acid Export Restriction Policies Strengthened Expectations for SX-EW Copper Production Cuts, and Supply Contraction Supported Copper Prices Sulphuric acid prices have been rising continuously since March, mainly due to the ongoing escalation of tensions in the Middle East. Shipping through the Strait of Hormuz, which carries approximately 50% of the world's seaborne sulphur volume, has been disrupted, leading to an overall tightening of global sulphur supply. In China's sulphuric acid production, approximately 40% comes from sulphur-based acid production and 40% from smelting acid. China is highly dependent on sulphur imports, and the tightness in raw material supply has provided certain support for domestic sulphuric acid prices. The DRC is the world's second-largest copper-producing country, with production highly dependent on sulphuric acid. According to SMM, producing 1 mt of copper cathode locally requires 2–6 mt of sulphuric acid. Based on an average of 4 mt, annual sulphuric acid consumption is approximately 10 million mt, of which more than half relies on imports from the Middle East. The Middle East is both a critical global energy transportation route and a core hub for sulphur trade. The current US-Iran conflict has lasted 46 days, and local smelter sulphuric acid inventory is at low levels. Coupled with China, as a major global sulphuric acid exporter, imposing export restrictions, ex-China sulphuric acid supply has tightened further. The sulphuric acid shortage has constrained SX-EW copper output to a certain extent, creating expectations of a contraction in global copper cathode supply and providing clear bullish support for copper prices. According to SMM, SX-EW copper production in the DRC and Zambia has been gradually suffering losses recently, especially at some smaller smelters. The originally projected SMM global copper cathode balance surplus for 2026 is expected to slow down YoY. Expectations of copper cathode supply losses have strengthened, and the market is expected to gradually shift from a loose balance to a tight balance. The tightening supply-side expectations are set to provide support for copper prices. II. Easing geopolitical tensions coupled with inflation pullback push the US dollar index lower, providing support for copper prices Earlier, the escalating tensions in the Middle East continued to push up energy prices, increasing inflationary pressures. Expectations for US Fed interest rate cuts cooled somewhat, and the market gradually priced in unchanged interest rates for the full year. Recently, signs of easing emerged in the geopolitical conflict. Trump stated that the US and Iran are expected to hold talks in Pakistan within the next two days. Pakistan called for a 45-day ceasefire extension, and both sides agreed to continue negotiations, with only the time and location yet to be determined. According to sources familiar with the matter, Iran is considering temporarily suspending shipping restrictions in the Strait of Hormuz to create a favorable atmosphere for negotiations, and the US military has no plan to attack Iranian oil tankers. On April 14, Trump publicly stated that the military campaign against Iran was nearing its end, with positive signals being gradually released, The pullback in crude oil prices and the weakening of the US dollar index provided some support for copper prices. Meanwhile, the pullback in oil prices eased inflationary pressures, leaving room for subsequent interest rate cuts, and sentiment improved somewhat. III. Social Inventory Declined for Five Consecutive Weeks; Combined with Peak Consumption Season and Maintenance Cycle, Tight Supply-Demand Conditions Supported Copper Prices After the Lantern Festival, copper prices gradually pulled back, downstream consumption recovered somewhat, and SMM social copper inventories in major regions across China continued to destock from mid-March. Recently, copper prices rebounded somewhat, downstream purchasing became more cautious, and the destocking pace slowed down. As of April 13, SMM social copper inventories in major regions across China had decreased from 578,900 mt on March 9, 2026 to 299,800 mt, maintaining destocking for five consecutive weeks. China is currently entering the traditional peak consumption season. Copper scrap policies still carry certain uncertainties, and the overall operating rate of scrap utilization enterprises remains relatively low, providing some support for copper cathode rod consumption. Meanwhile, global smelters are entering a concentrated maintenance period in Q2, further tightening the supply side. The continued decline in inventory, combined with a tight supply-demand pattern, is providing some support for copper prices. Overall, the macro front and fundamentals are currently forming a degree of resonance, providing relatively positive support for copper prices. From a macro perspective, geopolitical conflicts showed signs of easing, the US dollar index pulled back somewhat, and earlier inflationary pressures were alleviated to some extent. On the fundamentals side, tightening sulphuric acid supply constrained SX-EW copper output outside China, SMM China social inventory continued to decline, and combined with relatively strong domestic fundamentals, the supply-demand pattern showed a tightening trend. However, as copper prices rebounded above 100,000 yuan/mt, downstream acceptance weakened somewhat, and recent purchase willingness also turned slightly cautious. Going forward, it is worth watching whether actual demand performance during the traditional peak season can meet expectations against the backdrop of high copper prices.

SMM News, April 2: Data Brief: As of Thursday, April 2, SMM copper inventories in major regions across China fell 14.04% WoW from last Thursday. Total inventory increased 53,800 mt YoY from the same period last year, marking three consecutive weeks of destocking. By region, in Shanghai, copper cathode inventory continued to pull back, supported by downstream consumption, while smelters gradually entered the maintenance cycle and arrivals tightened, with warehouse withdrawals significantly exceeding inflows. In Jiangsu, downstream consumption steadily recovered, and inventory continued to decline in tandem. In Guangdong, consumption remained robust, and coupled with tight supply in some areas, inventory kept falling. Looking ahead, on the supply side, imported copper cargoes continued to arrive, while arrivals of domestically produced copper decreased somewhat due to smelter maintenance. On the demand side, downstream enterprises mostly purchased as needed based on their production pace. Judging from the overall supply-demand pattern, China’s copper cathode supply is expected to remain tight next week, while consumption is expected to stay broadly stable, and weekly inventory is expected to continue destocking.

[SMM Henan Copper Cathode Flash] The purchasing sentiment index in the Henan copper cathode market was reported at 2.6 today. Spot cargo available in the market was limited, and some downstream buyers mainly engaged in just-in-time procurement. Overall trading activity in the market was average.

[SMM Analysis] It cannot be ignored that the shortage of copper concentrates has gradually been transmitted to copper cathode. In the first half of 2024, there were continuous reports of production cuts and even shutdowns at overseas smelters. This indicates that despite the launch of new smelting and refining projects in the second half of the year (H2), the global supply of copper cathode will not ease.

[SMM Analysis: Deep B's performance is not enough, while transition to C is not yet complete] SMM believes that the backwardation structure of SHFE will weaken in the future market. The premise of our following discussion is based on the existing tariff levels in the US.
