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.

[Price Review] This week, Middle East geopolitical concerns resurfaced, with the US-Iran standoff continuing to escalate: on April 28, Iran demanded transit fees from vessels passing through the Strait of Hormuz; on April 29, the US explicitly prohibited its individuals and entities from paying such fees to Iran, while warning non-US entities that payment would face significant sanctions risks; on April 30, Trump reiterated that Iran's abandonment of nuclear weapons was the bottom line for negotiations, stating that communication with Iran was underway via phone. Middle East tensions and energy price fluctuations further amplified uncertainties over the global economic outlook, and precious metals remained under pressure. On the US Fed front, the April FOMC meeting maintained interest rates unchanged as expected, with internal policy divergence persisting—one member advocated for an interest rate cut while three members opposed releasing easing signals. Powell broke decades of industry convention by announcing that after stepping down as Fed Chairman, he would remain as a governor until early 2028; he explicitly stated that the Trump administration's legal actions were threatening the independence of the US Fed's monetary policy-making while undermining the institution's own stability. Whether the conflict risks further escalation will continue to dominate global market risk appetite and energy price fluctuations, exerting significant impact on silver price trends. Industrial demand side, sluggish downstream consumption persisted, and as spot silver prices declined, only some downstream enterprises opted to stockpile small quantities on dips. Gold/silver ratio side, as of April 29, the LBMA gold/silver ratio rose to 62. [Key Data] Bearish: Middle East geopolitical conflict continued to escalate, with the US-Iran standoff over Strait of Hormuz transit fees intensifying. Core negotiation demands were completely opposed, and the deadlock over waterway blockade and military confrontation remained unresolved, pushing up sticky inflation expectations and reinforcing the US Fed's stance of maintaining higher interest rates for longer. The US Fed's April FOMC meeting maintained interest rates unchanged as expected, with internal policy divergence hitting a 34-year high. The overall stance was neutral-to-hawkish, with no clear interest rate cut signal released. Market expectations for rate cuts within the year cooled significantly, and the US dollar and US Treasury yields fluctuated at highs, continuously suppressing silver valuations. Inflation stickiness in the US and Europe exceeded expectations. US March CPI rose to the highest YoY and MoM since 2024, and the eurozone March core CPI final reading was unexpectedly revised upward. Persistent inflation further weakened the necessity for central bank easing. US labor market resilience exceeded expectations. Initial jobless claims for the week ending April 11 posted the largest single-week decline since February, significantly below market expectations, completely eliminating market bets on an emergency US Fed interest rate cut. China's silver industrial demand remained weak, with downstream PV and electronics enterprises maintaining only just-in-time procurement. Social inventory of spot silver ingots continued to accumulate, and transaction discounts kept widening. Bullish factors: US March PPI data significantly missed market expectations, with YoY, MoM, and core PPI gains all well below forecasts, releasing signals of marginal inflation easing and preserving room for subsequent Fed interest rate cuts. Dovish divergence within the Fed persisted, with one committee member advocating an immediate rate cut at the April meeting; some officials still believed multiple rate cuts remained possible this year, keeping the rate cut window open and preventing a complete reversal of easing expectations. Concerns over slowing US economic growth emerged, with market expectations for US Q1 GDP growth pulling back sharply from the previous reading; stagflation and recession fears reinforced safe-haven demand for silver. Key data and macro events to watch next week include: May 1: Eurozone April CPI preliminary reading, US April ISM Manufacturing PMI. May 6: US March JOLTs job openings, April ISM Non-Manufacturing PMI. May 7: Bank of England interest rate decision, ECB April monetary policy meeting minutes. May 8: US April non-farm payrolls report. [Price Forecast] Recent precious metals market trading logic continues to revolve around re-escalating Middle East geopolitical concerns, inflation expectations driven by high oil prices, US Fed monetary policy expectations, and Fed Chairman transition and internal divergence. On the China fundamentals side, downstream consumption remained sluggish; as spot silver prices declined, only some downstream enterprises chose to stockpile small quantities on dips. The upward trend in spot silver ingot social inventory has yet to improve, and the market expects mainstream spot transaction discounts to remain within a narrow discount range relative to the SGE TD price. Silver prices are expected to remain under pressure with volatile trading next week.

[Silicon Metal Futures Center Shifted Higher with Increased Enterprise Shipments; Heavy Wait-and-See Sentiment in Polysilicon Market]: In the futures market, the most-traded contract trended stronger during the week, with the SI2609 contract center at 8700-8800 yuan/mt and the highest point touching above 8,900 yuan/mt. Driven by macro factors and news, futures rose, boosting silicon producers' shipment sentiment, and silicon enterprises' shipments to trading firms engaging in both spot and futures market increased. On the fundamentals side, silicon metal supply and demand were in tight balance in April, and the supply-demand structure is not expected to see major adjustments in May. Facing the pressure of increased supply during the rainy season in Sichuan and Yunnan from June to July, the market outlook leaned toward caution. On the cost side, raw material prices remained firm. With upside in silicon metal prices capped and downside supported by costs, the price fluctuation range was narrow.

[SMM Rare Earth Weekly Review: Rare Earth Price Fluctuations Narrowed Ahead of Labour Day Holiday] Pr-Nd oxide market prices pulled back slightly at the beginning of the week due to news-driven factors. However, given that spot supply of Pr-Nd oxide remained tight, upstream suppliers held firm on their offers, and low-priced cargoes remained hard to find. As of today, Pr-Nd oxide prices fluctuated and adjusted to 770,000-775,000 yuan/mt over the week.

[SMM Lithium Battery Electrolyte Market Weekly Review: Electrolyte Prices Remained Stable This Week (2026.4.27-4.30)] From April 27 to April 30, 2026, electrolyte prices remained stable. Future price trends will still need to focus on upstream raw material price movements.

Ahead of the Labour Day holiday, SMM surveyed galvanising enterprises on their holiday arrangements. This survey covered 27 galvanising enterprises with a total capacity of 20.10 million mt. According to SMM, some enterprises will take 1-13 days off during the Labour Day holiday, while others will maintain normal production without any break, with an estimated total impact on zinc consumption of approximately 5,785 mt.

Ahead of the Labour Day holiday, the magnesium market saw a recovery in trading activity during the first half of this week, with spot prices holding up well and magnesium prices rising for two consecutive days. Current market support mainly came from the continued release of pre-holiday rigid stocking demand from end-users, with downstream procurement pace following in an orderly manner, effectively revitalizing trading activity in the market. On the other hand, rising coal and ferrosilicon futures prices on the raw material side also provided certain cost support for the magnesium market. Supported by multiple positive factors, suppliers generally maintained firm pricing sentiment, low-priced spot cargo in the market gradually diminished, and the overall magnesium market showed a generally stable with slight rise trend. Magnesium prices rose for two consecutive trading days Spot price side: magnesium ingots and magnesium alloys continued the upward trend from the 28th. Specifically, the SMM 99.90% magnesium ingot (Fugu, Shenmu) price on April 29 was 16,600-16,700 yuan/mt, with an average price of 16,650 yuan/mt, up 0.3% from the previous trading day. The core driver behind this two-day consecutive rise in magnesium prices was pre-holiday restocking demand from downstream end-users. As the Labour Day holiday approached, considering the holiday factor, downstream deep-processing and manufacturing enterprises initiated stockpiling operations in advance, and market procurement enthusiasm improved compared to the previously sluggish conditions. Most downstream enterprises abandoned their earlier wait-and-see sentiment and entered the market to purchase based on their rigid production needs, proactively locking in spot inventory to hedge against post-holiday supply fluctuation risks. The sustained concentrated restocking demand rapidly consumed previously accumulated low-priced inventory in the market, with low-priced resources basically digested and cleared, the market price floor continued to rise, directly driving magnesium prices to raise consecutively. Overall trading activity and transaction sentiment in the market improved during the first half of this week. Outlook Based on the current supply and demand performance in the market, the concentrated release of pre-holiday restocking demand effectively reversed the previously weak market sentiment, boosting confidence among traders and producers to a certain extent. However, from the market pace perspective, after a round of concentrated restocking, downstream stocking demand had been gradually released, and the pre-holiday restocking trend was basically coming to an end. As the Labour Day holiday approached, market procurement activities gradually ceased, and concentrated trading momentum was expected to pull back. Based on current market conditions, domestic magnesium prices were expected to remain generally stable in the short term. In the long term, the domestic magnesium market needs to focus on two aspects going forward: first, the maintenance arrangements and production pace changes of domestic magnesium ingot producers — if mainstream smelters arrange concentrated equipment maintenance and production cuts later, this will directly compress overall market supply, alter the current supply-demand balance, and drive price fluctuations; second, the recovery of demand in markets outside China — currently, ex-China magnesium product demand remained generally stable but weak, and whether export orders can steadily increase and whether export markets can recover will directly affect domestic magnesium ingot exports, becoming an important factor influencing medium and long-term magnesium price trends.

[SMM Cast Aluminum Alloy Morning Comment: April Secondary Aluminum PMI Data Fell Below the 50 Mark, Off-Season Pressure Expected to Persist in May] The aluminum AL2606 contract opened at 23,010 yuan/mt in the night session, reaching a high of 23,120 yuan/mt and a low of 22,880 yuan/mt, closing at 22,940 yuan/mt, down 160 yuan/mt from the previous settlement price, a decline of 0.69%.

On April 21, a delegation from SMM Information & Technology Co., Ltd. (SMM), comprising Ye Jianhua, Director and Supervisor of SMM's Industry Research Department, Feng Chundi, Expert of SMM's Industry Research Institute, and Wu Tao, SMM's Overseas Marketing Manager for Copper and Tin, visited Lualaba Copper Smelter S.A. (LCS) for a field trip and exchange. The delegation received a warm and thoughtful reception from the leadership of LCS. During the exchange, relevant heads of LCS provided a detailed introduction to the project's construction history, smelting process routes, current capacity operations, and overall business planning. SMM, drawing on global non-ferrous market trends, shared insights on copper-cobalt raw material supply and demand, the smelting and processing landscape, price fluctuation trends, and industry policy developments. Both parties engaged in in-depth discussions on practical topics including production management and control in ex-China pyrometallurgy operations, raw material supply assurance, environmental protection operations and maintenance, cost management, and industry outlook assessment. They also exchanged experiences and ideas on the operational management, risk prevention, and medium and long-term development planning of smelters outside China. This field trip and exchange was pragmatic and efficient, effectively enhancing mutual understanding and laying a solid foundation for ongoing industry information sharing and long-term exchange and cooperation.
