The global stainless steel market navigated a series of sharp sentiment. The opening weeks saw Indonesia's mill closures and price hikes push the cost narrative to its highest point of the year, before a combination of easing geopolitical tensions triggered the first price reduction since December 2025. The month's defining characteristic was similar to April's. What differentiated May was the sharply higher amplitude of both the policy signals and the emotional swings that accompanied them.

[SMM Daily Review: Tight Supply Bolsters Willingness to Hold Prices Firm, NPI Price Center Rises] June 15 — SMM's high-grade NPI upstream sentiment factor was 2.74, up 0.01 MoM, and the downstream sentiment factor was 1.84, up 0.02 MoM.

[SMM Stainless Steel Daily Review] Stainless Steel Futures Stabilize, Spot Trades Pick Up SMM reported on June 12 that SS futures stopped falling and stabilized. News of easing US-Iran conflict emerged again, nonferrous metal futures generally staged a recovery, and SS strengthened in tandem. As of midday close, the most-traded SS contract was quoted at 14,715 yuan/mt. In the spot market, driven by the strengthening of SS futures, market activity improved. In the morning session, both inquiries and transactions recovered, and traders raised their offers. The most-traded SS futures contract pulled back. At 10:15 a.m., SS2607 was reported at 14,705 yuan/mt, up 300 yuan/mt from the previous trading day. Spot premiums for 304/2B in Wuxi ranged from 365-915 yuan/mt. In the spot market, the average price of cold-rolled 201/2B coil in Wuxi remained flat; for cold-rolled 304/2B trimmed edge coil, the average price in Wuxi rose 50 yuan/mt, and in Foshan rose 50 yuan/mt; cold-rolled 316L/2B coil in Wuxi fell 200 yuan/mt; hot-rolled 316L/NO.1 coil in Wuxi was flat; cold-rolled 430/2B coil in both Wuxi and Foshan held steady. This week, stainless steel futures and spot prices both declined under pressure, as macro headwinds outside China dominated the market and off-season pessimism spread quickly. The industry’s outlook expectations weakened, end-users remained on the sidelines, and rigid demand stayed sluggish. Traders concentrated on selling to destock and offered discounts. On the futures front, overseas macro developments were the core driver this week. The US non-farm payrolls data significantly exceeded expectations, the unemployment rate stayed low, and the market delayed or even canceled expectations for a US Fed interest rate cut within the year…

As of now, the Indonesia MHP nickel FOB price is $16,398/mt Ni, and the Indonesia MHP cobalt FOB price is $51,302/mt Co.

[SMM Nickel Flash] The average price of SMM 10-12% high-grade NPI declined WoW by 1 yuan/nickel unit to 1,143.1 yuan/nickel unit (ex-factory, tax included), while the average Indonesia NPI FOB index price fell WoW by $0.35/nickel unit to $147.33/nickel unit. This week, the NPI market was overall weak, with futures trends becoming the core factor affecting spot pace. Trading throughout the week was generally light, price divergences were significant, and structural gaming persisted throughout.

Philippine Market: Port inventories continued to accumulate, high freight costs coupled with smelters pushing for lower prices, ore prices faced increasing downside risks This week, CIF China quotes for Philippine nickel ore were generally flat WoW, with no significant loosening or increases across various grades. Specific quotes were: CIF China: Ni 1.3% at $49–52/wmt, 1.4% at $57–60/wmt, 1.5% at $65–67/wmt; CIF Indonesia: 1.3% at approximately $48–50/wmt, 1.4% at approximately $56–58/wmt. Supply and Weather As of June 12, Philippine nickel ore inventory at Chinese ports totaled approximately 5.77 million wmt, equivalent to around 45,300 mt in nickel metal content, up WoW as supply remained ample. Weather conditions at mining areas were relatively manageable, with no major typhoons or heavy rainfall disrupting supply chains recently. However, spot freight rates stayed high, providing minimal support for miners' FOB prices, intensifying cost pressure on miners' shipments. Some mines opted to hold off on shipments, awaiting next week's new round of bidding results before making decisions. Demand and Inventory Demand side, smelters' desire to bargain down prices remained strong, continuing to pressure miners with ample inventories, while the buyer-dominant landscape persisted. Smelters in both China and Indonesia held inventories that fluctuated at highs, with weak short-term restocking willingness and sluggish trading in the market. Considering the continued accumulation of port inventories, high freight costs squeezing miner margins, coordinated price pushing by smelters, and rising wait-and-see sentiment among miners, ore prices could edge down further in the coming weeks. Indonesian Market: Smelters' High Inventories Continued to Weigh on Prices, Premiums Showed a Narrowing Trend The HMA was unchanged at $18,799.29/mt. Theoretical HPM prices were: Ni 1.6% at approximately $70.75/wmt, 1.2% at approximately $49.84/wmt. The delivery-to-factory price for 1.6% ore was $73.8–78.8/wmt, with premiums at +3 to +8 dollars, flat WoW and significantly narrower than earlier highs. Looking ahead, with ore supply continuing to be ample and smelters' willingness to bargain down prices increasing, premiums are expected to have room to decline further. Indonesia's local ore supply was relatively abundant, with some mines taking advantage of weather windows to maximize production. According to BMKG: Sulawesi (Morowali Utara) experienced relatively dry weather with calm seas and smooth shipping; East Halmahera saw persistent rainfall with wave heights of 1.4–2.0 m; Obi had light rain with wave heights of 1.3–1.6 m, with shipment efficiency affected in both areas. This week, the saprolite ore market saw ample cargo availability and relatively active trading volumes. However, with inventories at many smelters staying at sufficient levels, the desire to push for lower prices strengthened noticeably. In some industrial parks, unloading vehicle queues appeared this week, directly reflecting the market reality of loose ore supply and persistently high delivery-to-factory volumes. Traded grades were concentrated at 1.45–1.50% Ni, while high-grade ore (≥1.6%) remained scarce. In addition, spot limonite ore was priced at approximately $26–34/wmt, with the price range widening. The market exhibited some divergence, with select transactions at lower prices and a few at higher levels, as the overall center shifted slightly lower WoW, mainly dragged down by high freight costs. The discount to the theoretical HPM price remained deep and detached. Sulphuric acid supply stayed relatively tight, HPAL operating rates were low, and purchasing prices for limonite ore remained under pressure. Policy Developments Newly approved RKAB for nickel ore were relatively rare this week, with the market widely expecting more approvals to be released in July. Meanwhile, Indonesian Energy and Mineral Resources Minister Bahlil Lahadalia stated that the government would implement an "orderly and flexible" policy for 2026 mineral and coal RKAB, where production quota adjustments would be linked to global commodity price trends and domestic industrial demand—moderately expanding production when prices rise and tightening promptly when prices are under pressure to maintain supply-demand balance. This statement reserved policy space for within-year quota revisions, warranting ongoing market attention to the release periods of subsequent official documents. The DSI takeover mechanism for ferroalloy exports entered a transition period on June 1, with NPI (HS 7202.60.00) highly likely to be included; Harita’s PT Trimegah had already completed the first DSI single-window export declaration, with smooth operations. The government was simultaneously pushing forward a strict crackdown on under-invoiced contracts, with relevant departments set to consult with industry associations to close loopholes.
