As a core vital raw material for manganese hydrometallurgy, sulfuric acid dominates production costs and process selection across the entire product chain. Major manganese products, including electrolytic manganese, diversified manganese sulfate, and electrolytic manganese dioxide (EMD), adopt distinct production processes with varied acid consumption structures.

In the manganese-based hydrometallurgy industry chain, sulphuric acid is not merely an ordinary auxiliary material, but rather a core lifeline raw material that runs through the production of all product categories, controls production costs, and influences process selection. Mainstream products such as EMM, various grades of manganese sulphate, and EMD differ vastly in production processes and have entirely distinct acid consumption structures, which also leads to completely stratified sensitivities of various manganese products to sulphuric acid price fluctuations. Every round of change in acid prices transmits from top to bottom, directly reshaping the cost structure and market dynamics of the manganese industry chain.

[SMM Analysis] Macro Sentiment Weighed on Futures, Stainless Steel Profits Narrowed Amid Raw Material Divergence Stainless steel production costs pulled back this week, and steel mill profits narrowed, with profit divergence driven by differing raw material inventory costs. Using 304 cold-rolled as the calculation benchmark, the profit margin based on current raw material costs was 1.87%, while the profit margin based on low-level inventory raw material costs was 4.48%. Overall industry profitability remained moderate, steel mills maintained high production schedules, and operating rates stayed stable. Nickel-based raw material costs: Nickel-based raw material prices came under pressure this week, largely driven by futures sentiment. SHFE nickel and stainless steel futures declined consecutively, pulling high-grade NPI market prices down in tandem. However, cost support in the NPI industry remained strong, with widespread firm-pricing sentiment across the market. Additionally, high-grade NPI sources with higher nickel content were scarce within the industry, resulting in structural price divergence in NPI, with prices for high-grade NPI above 12% grade remaining firm. As of this Friday, mainstream 10-12% grade high-grade NPI fell 6 yuan per nickel unit, closing at 1,145 yuan/nickel unit. Stainless steel scrap market: Stainless steel scrap prices pulled back this week. SS futures trended weaker, dragging spot prices lower in tandem. Although high-grade NPI also declined, the drop was limited, highlighting the cost advantage of stainless steel scrap. Steel mill smelting profits remained moderate, production schedules stayed high, and procurement demand remained solid. The overall picture showed "weak futures, resilient raw materials...

US dollar: Overnight, the US dollar index rose 0.41% to 98.88. According to Wallstreetcn, US April retail sales posted the strongest gain in 8 months, confirming consumer resilience, but inflationary pressures continued to build. Combined with rising long-term Treasury yields, market expectations for a US Fed interest rate cut have largely faded. US Fed Governor Barr stated that easing liquidity rules to shrink the central bank's balance sheet is a bad idea that could undermine the safety of the financial system. "There has been a lot of discussion recently about shrinking the size of the Fed's balance sheet to reduce our 'footprint' in the financial system," Barr said in prepared remarks for a conference hosted by the NYU Money Marketeers. "I believe shrinking the balance sheet is the wrong objective, and many of the proposals put forward to achieve it would weaken bank resilience, impede the normal functioning of money markets, and ultimately threaten financial stability," Barr said. "Some proposals would actually increase the Fed's 'footprint' in financial markets." Barr noted that allowing banks to reduce their liquidity holdings as a means of shrinking Fed assets could increase the risk that these institutions would need to turn to Fed liquidity facilities when in distress. He said, "The size of the Fed's balance sheet is not the right measure of its influence in financial markets," and in a system where the Fed creates reserves "at no cost," the real focus should be on the effectiveness of the Fed's monetary policy implementation. (Jin10 Data) According to Reuters, Milan formally submitted his resignation to the US Fed on Thursday local time, setting his departure date on or shortly before the day Waller is sworn in. Waller is expected to be sworn in as Fed Chairman within the coming days. In his resignation letter, Milan continued to warn that interest rates may be too high. He wrote that broader economic trends such as slowing population growth and deregulation would reduce inflation on their own, giving the Fed room to ease policy. He also argued that technical challenges in measuring inflation may cause inflation statistics to overstate actual levels.

Crude oil: Overnight, both oil futures rose, with WTI up 0.99% and Brent up 0.91%. Market concerns over supply disruptions amid the US-Iran conflict persisted, supporting oil prices. US Treasury Secretary Bessent stated that Iran's oil storage is full and Tehran will need to halt oil production. Following the US blockade on Iranian oil exports, the key question in this conflict is: how long can Iran store the oil it cannot export before running out of space. Some analysts believe Iran still has a few weeks of storage capacity, and Tehran has begun slowly cutting production to cope with the standoff. Bessent said in an interview on CNBC's "Squawk Box" that over the past three days, Iran has been unable to load tankers at its main oil export terminal, Kharg Island, as the US blockade prevented tankers from entering or leaving the Persian Gulf. In the first month of the US blockade, the US military forced 70 vessels allegedly heading to or from Iranian ports to change course. (Jin10 Data) According to Bloomberg ship-tracking data, four VLCCs loaded with crude oil have transited the Strait of Hormuz since May 10, with combined daily flows approaching 2 million barrels. However, this improvement was relatively limited. Freight analyst Georgios Sakellariou stated: according to Bloomberg ship-tracking data, four VLCCs loaded with crude oil have transited the Strait of Hormuz since May 10, with combined daily flows approaching 2 million barrels. However, this improvement was relatively limited. Goldman Sachs analyst Tallulah Adams noted that the oil market has entered a narrower trading range, with realized volatility over the past 5 days falling to the lowest level since the conflict began, and the market is largely in wait-and-see mode. Weak physical market signals suggest supply remains adequate for the May trading cycle, but Goldman Sachs also cautioned that the coming weeks will be critical as the summer peak demand season is about to arrive. (Wallstreetcn) Additionally, two industry sources told Reuters that a Gazprom natural gas processing plant in Russia's southern Astrakhan region suspended motor fuel production after a fire on May 13. The fire was caused by a drone strike. They said the plant suspended operations, including a stabilized condensate processing unit with an annual capacity of 3 million mt that produces gasoline and diesel. According to sources, restoring motor fuel production could take weeks to months. The second source said hydrogen sulfide treatment and sulfur recovery equipment were also damaged in the drone strike. Industry sources said the Astrakhan plant processed 1.8 million mt of stabilized natural gas condensate in 2024, producing 800,000 mt of gasoline, 600,000 mt of diesel, and 300,000 mt of fuel oil.
