Yesterday, the domestic coking coal futures market experienced sharp fluctuations due to rumors that "Mongolia plans to raise the mineral resource tax on coal from the current level to 20%." The most-traded contract saw a single-day increase of over 7% at one point, sparking market concerns about rising costs for imported coking coal. Az, Deputy General Manager of Golomt Capital LLC (Golomt Securities), a member of the Mongolian Mineral Exchange and a Mongolian securities company, told a reporter from Cailian Press: "The government submitted a new draft tax law to the State Great Khural yesterday. I heard that the draft proposes to increase the special tax on the use of mineral resources (AMNAT) to 20%, but this is just a rumor." Industry insiders both domestically and overseas believe that the likelihood of a policy adjustment is relatively small. Recently, the market was suddenly abuzz with news that "Mongolia plans to raise the coal resource tax to 20%," leading to a significant gap-up opening in domestic coking coal futures prices. On June 4, the most-traded coking coal futures contract reached a high of 1,285 yuan/mt, up 7.19% from the previous trading day's closing price. A reporter from Cailian Press learned from relevant sources in Mongolia and domestic Ganjimod coal importers that there is currently no official information supporting this news. Senior executives from Golomt Securities disclosed to a reporter from Cailian Press that they had consulted with the Ministry of Finance and the General Taxation Bureau, confirming that "apart from this draft tax law, no other bills related to AMNAT have been submitted." Az told a reporter from Cailian Press: "The Tax Policy Department of the Ministry of Finance (of Mongolia) participated in drafting this tax bill. We specifically inquired with the Ministry of Finance, the General Taxation Bureau, as well as places like 'Erdenes Tavantolgoi,' Energy Resources, and the Mongolian Stock Exchange. They all said, 'There are no changes to AMNAT.' The Ministry of Finance and the General Taxation Bureau also clearly stated that the new draft does not involve any changes to AMNAT. Companies like 'Erdenes Tavantolgoi' and Energy Resources have not received any information about tax rate adjustments either. Because such tax rate changes must go through legal procedures and be approved by the State Great Khural." Xu Xiao, head of the Mongolian Research Society based in Ulaanbaatar, also discovered through reviewing recent legislative documents that "no relevant adjustments have been mentioned by official channels such as the Ministry of Finance and the Mineral Resources Authority." Mongolian coal exports surged from 16 million mt in 2021 to 89 million mt in 2024. However, due to the sluggish coal market this year, Mongolian coal exports have recently decreased. Domestic coal importers believe that the likelihood of a short-term adjustment to Mongolia's resource tax is relatively small. Manager Zhang, a staff member of Tangshan Jiyunda Cargo Handling Co., Ltd. stationed in Ganjimod, told a reporter from Cailian Press that the current price of Mongolian No. 5 coal has fallen back to pre-2018 levels, and sales are currently difficult. If Mongolian coal prices rise due to an increase in the resource tax, it will be difficult for the downstream market to absorb the cost. Manager Tan, the head of Ganjimaodu Pinchuang Trading, believes that from the perspective of market supply and demand, Mongolian coal does not currently meet the conditions for tax increases. Even if taxes are increased in the future, due to the lengthy approval process, they will not be implemented in the short term. This statement is similar to the views expressed by individuals within Mongolia. Az told a reporter from Caixin that even if there are relevant proposals in the future, the process can only be initiated and submitted to the State Great Hural after the appointment of a new prime minister, and the deliberation by the State Great Hural will also take at least 1-2 months.

[SMM Daily Review of Coking Coal and Coke] In terms of supply, the profitability of most coking enterprises has improved, and their production enthusiasm is moderate, with the actual supply remaining relatively loose. On the demand side, affected by the traditional off-season, steel mills are facing increased inventory pressure on finished products, and pig iron production continues to decline, resulting in reduced rigid demand for coke. In summary, the fundamentals of coke are bearish. However, driven by market sentiment in the futures market, market confidence has increased. This week, coke prices may remain in the doldrums.

This week, the cost of 304 stainless steel continued to decline, with nickel and chromium prices also weakening, further loosening the cost support for stainless steel prices. In terms of nickel-related costs, the price of high-grade NPI continued to fall, with the low point this week reaching 980 yuan/mtu. However, due to thin profits for high-grade NPI smelters and the implementation of new resource tax regulations in Indonesia, the room for further price declines was limited. Data shows that the price of 10-12% high-grade NPI dropped by 10.5 yuan/mtu this week, closing at 986 yuan/mtu. Notably, driven by its economic advantages, the supply of stainless steel scrap became slightly tight, and its price strengthened in tandem with the rise in stainless steel finished product prices. Specifically, the price of 304 off-cuts in east China rose by 250 yuan/mt this week, reaching approximately 9,850 yuan/mt. In terms of chromium-related costs, the retail price of high-carbon ferrochrome experienced a slight pullback. Although the futures price of South African 40-42% chrome concentrate ore rose above $300/mt during the week, the previous significant increase in ferrochrome prices had already restored profits for ferrochrome producers. Additionally, against the backdrop of low stainless steel prices, market expectations for next month's high-chromium steel tenders were pessimistic, prompting the retail price of high-carbon ferrochrome to stop rising and pull back. Specifically, the price of high-carbon ferrochrome in Inner Mongolia fell by 100 yuan/50 base mt this week, dropping to around 8,350 yuan/50 base mt. Currently, as stainless steel costs further declined and prices slightly rebounded, the losses of stainless steel mills narrowed. Taking 304 cold-rolled steel as an example, based on the raw material costs of the day, the cash cost decreased by 42 yuan/mt during the week, reducing the loss margin to 6.87%. Based on raw material inventory costs, the cash cost decreased by 43 yuan/mt, with a loss of 4.39%. Looking ahead to next week, stainless steel costs are expected to continue to decline. Meanwhile, as stainless steel finished product prices stop falling and rebound, the previous situation of inverted costs and prices for stainless steel mills may be alleviated to some extent.
