[SMM Lead Morning Meeting Summary: Macro Factors and Fundamentals Present Both Bullish and Bearish Signals, and Lead Prices May Continue to Consolidate in the Short Term] Fed Chairman Powell released dovish signals, and the market once again bet on the possibility of an interest rate cut within the year. Recently, production at primary lead and secondary lead smelters has resumed, supply has been relatively ample, and imported lead has continued to flow into China...

Since the beginning of this year, the spot treatment charge market for copper concentrates has shown an unprecedented and severe downward trend. The SMM Copper Concentrate Spot Index has fallen from -45 USD/dmt at the start of the year to near -70 USD/dmt, with the speed and magnitude of the decline being historically rare. A negative treatment charge means that when smelters purchase copper concentrates, they not only fail to receive traditional processing income from miners but instead must pay the sellers. Based on the current TC of -70 USD/dmt, the actual cost smelters pay sellers in the copper smelting process is equivalent to a TC of 70 USD, or further converted to a TC+RC of approximately 112 USD. This extreme price signal has quickly drawn high market attention to smelter profitability and even sparked concerns about the sustainability of domestic copper smelting production. Despite treatment charges falling to historic lows, copper cathode production by Chinese smelters remains at high levels, currently around 1.2 million tons per month. This phenomenon of "producing more while losing more" appears, on the surface, to contradict market logic, but actually reflects smelters' passive choices and structural supporting factors in the current complex environment. Historically, extreme treatment charge scenarios are not unprecedented. In past industry downturns, smelters often relied on one or several factors—exchange rate fluctuations, rising sulfuric acid prices, or treatment charges themselves—to barely maintain cash flow balance. In the current cycle, the sharp rise in sulfuric acid prices has become a key variable supporting smelter survival. Currently, the ex-factory prices of smelter acid sold by domestic copper smelters generally range from 800 to 1,600 yuan per ton. The latest SMM Copper Smelting Acid Index stands at 1,235.5 yuan/ton. As a crucial byproduct of copper smelting, sulfuric acid price fluctuations significantly impact smelters' comprehensive earnings. Typically, smelters produce approximately one ton of sulfuric acid for every dry metric ton of copper concentrate processed. Based on the current sulfuric acid price of 1,235.5 yuan/ton, after deducting value-added tax (at a 13% rate) and converting to US dollars (using an exchange rate of 6.9), each ton of sulfuric acid can contribute about 158 USD in revenue for the smelter, equivalent to an additional 158 USD per dry metric ton of copper concentrate. If further converted to the TC+RC metric, this amounts to about 99 USD. Thus, the rise in sulfuric acid prices has significantly offset the loss pressure from negative copper concentrate treatment charges, with some more efficient smelters even achieving marginal profitability. It is precisely this "stabilizer" role of sulfuric acid that allows smelters to maintain high operating rates under extreme treatment charge conditions. However, the support of sulfuric acid for smelting profits is not unlimited, as its price trend is itself influenced by more complex international geopolitical factors. The recent sharp escalation of the Middle East situation has brought significant uncertainty to the global sulfuric acid and sulfur supply chain. Since the joint US-Israeli military strike against Iran on February 28, 2026, the Strait of Hormuz, the world's most critical energy transport route, has rapidly fallen into a severe transit crisis. After taking office, Iran's new Supreme Leader, Mojtaba Khamenei, immediately declared that the strait would remain closed as a strategic lever against the US-Israeli alliance and suggested that neighboring countries close US military bases. The Islamic Revolutionary Guard Corps subsequently explicitly announced a ban on any vessels associated with the US or Israel from passing through the Strait of Hormuz, warning of severe consequences for unauthorized passage. The Strait of Hormuz is a critical chokepoint for global sulfur transport. Statistics show that before the conflict, over 100 ships passed through the strait daily. However, after the conflict erupted, transit traffic plummeted by over 90%, with extreme cases of no ships passing for an entire day, leaving over 3,000 vessels stranded in nearby waters. This effective blockade has not only directly impacted the crude oil market—with Brent crude futures rising over 50% within a month to exceed 114 USD per barrel—but has also severely disrupted the global supply chain for sulfur and sulfuric acid. War risks have caused shipping insurance costs to soar to over 20% of the cargo value, further increasing logistics costs and plunging global sulfur supply into a logistical crisis. Although Iran claims to allow passage for vessels from "non-hostile" countries, requiring them to obtain prior permission, actual transit volumes remain extremely low, far below global trade demand. Simultaneously, the Houthi armed group in Yemen has announced its involvement, posing new security threats to the Red Sea-Suez route. The compounding pressure on the two major shipping chokepoints of the Strait of Hormuz and the Red Sea is posing a systemic challenge to the global supply chains for energy and chemical raw materials. As the primary raw material for sulfuric acid production, the disruption in sulfur supply directly drives international and domestic sulfuric acid prices progressively higher. Given the current situation, geopolitical conflicts show no signs of easing in the short term, implying further room for sulfuric acid price increases. The continued rise in sulfuric acid prices will have a dual impact on the domestic copper smelting industry. On the one hand, increased sulfuric acid revenue will continue to provide crucial profit supplementation for smelters, enabling them to maintain production even at lower TC levels and potentially further depressing spot copper concentrate treatment charges. On the other hand, this surge in sulfuric acid prices, driven by geopolitical conflict, also makes smelter profitability highly dependent on external unstable factors, rendering the industry's overall risk resilience increasingly fragile. Notably, the extreme treatment charge environment has begun to have a tangible impact on the global layout of copper smelting capacity. Mitsubishi Materials of Japan recently announced its plan to cease operations at its Onahama copper smelter by the end of March 2027. The smelter has a crude and refined capacity of 230,000 tons, and the main reason for the closure is precisely the intensified competition in the global copper smelting industry, leading to a sharp deterioration in copper concentrate TC/RC and persistent pressure on business prospects. This decision sends a clear signal: against the backdrop of continuously bottoming treatment charges and industry profits highly dependent on byproducts and external environments, some high-cost smelting capacity or those lacking comprehensive recovery capabilities are facing pressure to exit the market. In summary, China's copper smelting industry is currently at a highly unusual cyclical juncture. On one hand, smelters, benefiting from high sulfuric acid prices, have temporarily weathered the impact of negative treatment charges, maintaining high output. On the other hand, sulfuric acid prices themselves are heavily dependent on geopolitical situations, and external variables like the Strait of Hormuz blockade introduce significant uncertainty into the sustainability of smelting profits. If tensions in the Middle East persist, sulfuric acid prices may continue to rise, leaving room for TC to fall further, potentially enhancing smelters' tolerance for extreme treatment charges in phases. However, if geopolitical tensions ease, sulfur supply chains recover, and sulfuric acid prices retreat from their highs, smelters would face the risk of a "double blow" from both low treatment charges and reduced byproduct revenue, potentially heralding a genuine phase of capacity reduction and deep adjustment for the industry. Therefore, the current apparent "resilience" of the copper smelting industry is essentially built upon a fragile balance between geopolitical factors and the byproduct market. For market participants, besides monitoring TC trends, it is crucial to closely track changes in sulfuric acid prices and the underlying geopolitical factors to make more accurate judgments regarding the production sustainability and profitability prospects of the smelting industry.

The gold price is currently causing nervousness once again. Since the start of the war involving the USA and Israel against Iran, the precious metal has recorded a daily loss of 4% for the second time.

[Price Review] During the week, silver prices remained in the doldrums. In China, the Ag (T+D) contract on the Shanghai Gold Exchange broke below the support level of 18,000 yuan/kg, while LBMA silver prices kept probing lower after falling below $75/oz. From a macro perspective, escalating geopolitical conflict in the Middle East pushed oil prices to repeated new highs, while intensifying inflation concerns significantly cooled expectations for US Fed interest rate cuts and delayed the timing of the first cut to year-end. The simultaneous strength in the US dollar index and US Treasury yields became the core factors suppressing silver prices. On Wednesday local time, the US Fed announced that it would keep interest rates unchanged. In the statement released that day, it noted that the impact of the Middle East situation on the US economy remained uncertain and that uncertainty surrounding the US economic outlook was still elevated. In addition, speculative demand and ETF holdings continued to decline, and market sentiment kept cooling. As for the gold/silver ratio, because silver posted a deeper decline, the ratio continued to rise. As of March 18, the LBMA gold/silver ratio had climbed to 63, a recent high. [Important Data] Bullish: US preliminary March one-year inflation expectations came in at 3.4%, above expectations and unchanged from the previous reading Bearish: US API crude oil inventory for the week ended March 13 increased by 6.556 million barrels, above expectations and the previous reading US EIA crude oil inventory for the week ended March 13 increased by 6.156 million barrels, above expectations and the previous reading Data and macro releases to watch next week include: Continued hawkishness from the US Fed, the ECB rate decision, US inflation/employment data, COMEX silver delivery, together with the Boao Forum and geopolitical risks On March 19, the FOMC kept rates unchanged at 3.50%–3.75%, raised its 2026 PCE forecast to 2.7%, and expectations for US Fed interest rate cuts cooled sharply. US-Iran Situation: As of March 19, the military strikes by the US and Israel against Iran had entered their 19th day, with high-intensity confrontation, no sign of a ceasefire, and the conflict spreading to multiple Gulf countries. In terms of the current impact on precious metals, financial suppression outweighed safe-haven demand. Against the backdrop of surging inflation expectations, the US dollar and US Treasury yields continued to rise, the timing of US Fed interest rate cuts was delayed, and silver prices were suppressed. [Price Forecast] Silver prices are expected to maintain a fluctuating trend in the doldrums amid the interplay between macro disruptions and fundamentals. On the macro front, caution is still warranted over the risk of continued US dollar strength and heightened volatility from any further escalation in the US-Iran conflict. On the fundamentals side, as PV export rush orders gradually approached their end, rigid demand for raw material procurement by silver nitrate enterprises declined in late March, weakening support from industrial demand. In China's spot market, as investment demand and rigid industrial demand softened, coupled with replenishment from imported silver ingots, circulating supply of silver ingots in the spot market became ample, and suppliers generally lowered spot premium quotes to facilitate transactions. The abnormally high spot premiums in China's spot market will come to an end. At the same time, profitability on imported silver ingots will also decline sharply, and spot premium quotes in actual spot silver ingot transactions are expected to return to rational levels.
