【SMM Analysis】Off-Season Strain: Si-Mn Stocks Pile Up, Output Cuts to Stay

Published: Jul 31, 2026 21:07
Since entering Q2 2026, the silicon manganese alloy market has remained under sustained pressure. Prices of upstream raw materials—including manganese ore and coke—have stayed elevated, while downstream steel consumption remains sluggish amid strong price-suppression efforts from mills. The industry is caught in a dual squeeze of “high costs and weak demand,” with losses spreading rapidly from isolated cases to a widespread trend.

Since entering Q2 2026, the silicon manganese alloy market has remained under sustained pressure. Prices of upstream raw materials—including manganese ore and coke—have stayed elevated, while downstream steel consumption remains sluggish amid strong price-suppression efforts from mills. The industry is caught in a dual squeeze of “high costs and weak demand,” with losses spreading rapidly from isolated cases to a widespread trend. Consequently, alloy producers across major northern and southern production hubs have successively initiated production curtailments and maintenance schedules. Although the traditionally high operating rates in North China have shown clear signs of easing, the impact of new capacity ramp-ups this year has partially offset these cuts. As a result, the decline in total national output has been less pronounced than expected, leaving supply-side adjustments stuck in a phase characterized by “strong expectations but slow implementation.”

Distinct operational trends have emerged across key production regions:

Inner Mongolia:​ Cost support remains firm, and anticipated production cuts are materializing. Electricity settlement prices in June held steady overall; however, due to reduced wind and solar power generation during the minor wind lull season, factories widely anticipate upward pressure on July’s settlement rates, sustaining the cost floor. Most producers are now facing deep losses, leading to a marked decline in production enthusiasm. Since July, smelters have rolled out output cuts and load reductions. Market sentiment is cautious; most operators indicate they will await profit recovery signals before resuming full operations opportunistically ahead of the traditional “Golden September, Silver October” peak season. Overall, the Inner Mongolia market is in a stalemate between “firm cost support” and “sluggish demand,” with both upstream and downstream participants adopting a wait-and-see stance.

Ningxia:​ Losses have intensified, making supply contraction in this region the most pronounced nationwide. Suppressed by sustained deficits, the scale of production curtailments continues to deepen; current daily output has fallen to merely around one-third of total capacity, with little expectation of a short-term rebound in production enthusiasm. On the trading front, futures prices remain range-bound with a bearish bias, leaving producers without a viable window for hedging. Concurrently, basis traders have adopted a cautious approach to procurement, resulting in sluggish inventory digestion at plants and the gradual emergence of stockpiling pressure.

Southern Region:​ Performance is highly bifurcated. Yunnan stands out as relatively active, whereas Guangxi and Guizhou are clearly under pressure. The arrival of the abundant hydro season has highlighted Yunnan’s advantage in lower electricity costs, somewhat boosting local production morale. However, field surveys reveal that most plants are still hovering on the brink of profitability, leading to divergent production paces. Some enterprises are opting for load reductions and semi-operational schedules to mitigate risks. In contrast, high-cost regions like Guangxi and Guizhou are severely impacted by elevated power tariffs. Lacking any profit margin, firms in these areas are unable to initiate substantive production increases, resulting in notably low market activity.

Outlook:​ Currently, the domestic silicon manganese market is defined by a trio of characteristics: "order-based production, inventory accumulation, and load reduction." Against the backdrop of compressed margins at steel mills, tender pricing fails to provide smelters with reasonable profit buffers, while speculative demand from traders and basis merchants has simultaneously weakened. Given that the traditional consumption off-season is not yet over and a recovery in end-user demand will take time, both social and plant inventories are expected to remain elevated in the near term, with destocking progressing slowly. In this environment, alloy producers will likely maintain their strategy of low-load operations and output controls, biding their time until signals of marginal demand improvement emerge toward the end of Q3.

From Tailings to Turnaround: Eastplats' Chrome Output Triples as Crocodile River Mine Delivers a Rare PGM Junior Win
[SMM Express] Eastern Platinum's Crocodile River Mine has completed a rare turnaround among South African PGM juniors, with chrome concentrate output climbing to 82,120 tonnes in 2025, up 353% from 18,118 tonnes in 2024. The gain came alongside a 59% rise in PGM concentrate production to 5,146 tonnes, lifting mine operating income to US$1.7 million, up 113% year-on-year, and narrowing the fourth-quarter net loss by almost 40%. The recovery reflects Eastplats' shift from a tailings-retreatment chrome operation into a growing metallurgical chrome and PGM concentrate producer, following the 2024 commissioning of a processing facility handling UG2 run-of-mine ore from the Zandfontein underground section. That momentum carried into Q1 2026, with chrome concentrate volumes up 71.7% year-on-year, even as PGM concentrate sales to Impala Platinum continued to account for the bulk of revenue. The chrome ramp-up gives Eastplats a growing secondary exposure to stainless steel raw material markets alongside its core PGM business.

Limpopo's Illegal Chrome Mining Crackdown Widens: Arrests, Truck Seizures and Asset Forfeitures Mount in 2026
[SMM Express] South Africa's enforcement drive against illegal chrome mining in Limpopo has escalated through mid-2026, with the Hawks arresting five suspects, aged 43 to 50, at an illegal chrome mining site in the Thabazimbi policing area on 12–13 July. The operation, run by the Limpopo Serious Organized Crime Investigation team alongside local SAPS units, the Criminal Record Centre and the Department of Mineral and Petroleum Resources, resulted in charges of illegal mining and contravening environmental law; the suspects appeared at the Thabazimbi Magistrate's Court on 14 July. The arrests form part of a broader, active pattern rather than an isolated incident. In late May, the Asset Forfeiture Unit secured a R4.5 million forfeiture order covering trucks and trailers linked to illegal chrome mining in the Sekhukhune district, and in early July a separate court ruling allowed authorities to seize seven trucks loaded with chrome ore from another illegal operation. Together, the cases point to sustained, coordinated action across Limpopo's chrome belt targeting the trucks, sites and proceeds tied to unlicensed chrome extraction.
