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.

At 4:15 PM on June 8, 2026, a ladle explosion at the SMS-1 steelmaking shop of Visakhapatnam Steel Plant (VSP) — operated by Rashtriya Ispat Nigam Limited (RINL) — unleashed molten metal at over 1,500°C onto the working platform below Caster-2. According to a preliminary report by India's Chief Inspector of Factories, the cause was a sudden release of gas entrapped within the liquid steel, which ruptured the ladle seal before the sliding gate was opened, triggering a catastrophic spill.

[Iran] Iranian steel billet export offers remain stable at 410-420 USD/tonne FOB or FCA border, primarily shipped from Bandar Abbas to Oman (with freight rates around 40-45 USD/tonne). However, impacted by surging sea freight costs and heightened security risks in the Middle East Gulf region, buyers have lowered their counterbids to 400-405 USD/tonne FOB. Market participants report that at least three vessels are currently waiting to berth, and overall port activity remains subdued. The hindered seaborne trade has prompted export activities to shift toward road transport; recently, approximately 20000 tonnes of billets were traded at 385 USD/tonne EXW for July delivery, with 130x130 mm billets seeing the strongest demand. SMM anticipates that as long as shipping disruptions in the Strait of Hormuz persist, seaborne exports will remain constrained, and short-term regional trade flows will continue to lean heavily on land transport to neighboring countries.

China’s coal-based LPG sector is set for rapid expansion as a wave of coal-to-olefins and coal-liquefaction projects come online between 2026 and 2028. Coal-based LPG marketable volume reached 1.8 million tonnes in 2025, accounting for about 7% of national LPG supply. Supported by significant cost advantages, coal-based production margins exceed oil-based routes by more than RMB1,000 per tonne. Most new capacity will be concentrated in Xinjiang and Inner Mongolia, potentially reshaping domestic LPG trade flows. Analysts expect LPG shipments from southern Xinjiang to increasingly move toward southwestern China, adding supply pressure to markets such as Chongqing and Sichuan. However, the start-up of the Tarim Ethylene Phase II project is expected to increase local LPG consumption and reduce regional oversupply risks.

South America remains the cornerstone of global copper supply, with Chile and Peru collectively accounting for more than one-third of global mined copper production. As electrification, grid modernisation, renewable energy deployment and AI-driven infrastructure investment continue to reinforce long-term copper demand growth, policy developments across the region are becoming increasingly important determinants of future supply availability.

As resource security and decarbonization become increasingly important, major economies are strengthening efforts to retain aluminum scrap. From the EU's review of export controls and the U.S. strategic asset proposal to Japan's circular economy initiatives and policies in the UAE and South Africa, these developments could reshape global scrap flows and affect secondary aluminum markets.

The Bureau of International Recycling (BIR) reported that global recycled steel consumption grew by 4.5% year-on-year to 480 million metric tons (mt) in 2025 across key markets, even as global crude steel output fell by 1.9% to approximately 1.85 billion mt. Global direct reduced iron (DRI) production also climbed 4.9% to 153 million mt, largely driven by India's 7.4% output increase to 58.9 million mt. In terms of trade flows, the EU-27 and the US remained the largest scrap exporters at 16.68 million mt and 11.76 million mt, respectively, while Turkey retained its position as the top importer with 18.76 million mt despite a 6.6% volume decline. Pakistan posted exceptionally strong import growth, surging 39.8% to 3.02 million mt. This decoupling of scrap consumption from total crude steel production underscores the accelerating global shift toward lower-carbon electric arc furnace (EAF) steelmaking. The sustained demand for scrap and DRI signals structurally tighter future raw material supplies, which will continually reshape global trade dynamics as countries secure resources for decarbonization.

Japan's Ministry of Economy, Trade and Industry (METI) has officially initiated an anti-dumping investigation into cold-rolled coil (CRC) and hot-rolled coil (HRC) imported from South Korea, China, and Taiwan. The probe, prompted by petitions from domestic producers including Nippon Steel and JFE Steel, targets the growing market penetration of these imports. According to METI, CRC import volumes increased from 830,818 metric tons (mt) in fiscal year 2021 to 874,353 mt in fiscal year 2023, while HRC imports surged from 1.22 million mt in FY2021 to 1.43 million mt between October 2024 and September 2025. Scheduled to conclude within one year, this defensive trade measure highlights the intense pressure on Japanese steelmakers caused by lower-priced imports amid stagnant domestic demand. If duties are imposed, it could significantly restrict regional trade flows, forcing foreign suppliers to divert tonnages elsewhere while simultaneously tightening local supply to support the profit margins and pricing power of Japanese mills.

In May 2026, global square billet markets exhibited a generally upward but fragmented trend, with average prices in most regional markets rising by $10–$20 per metric ton (mt). Black Sea FOB billet prices climbed by $13 to reach a 2025-high of $483/t, while Italy's Ex-Works prices increased by $18 to $621/t. Conversely, the Gulf region experienced a slight decline, with prices dropping from $518/t to $514/t. Furthermore, the National Bank of Ukraine forecasts that average billet prices will rise 4.9% year-on-year to $487.7/t FOB Ukraine in 2026. The mixed price movements highlight shifting trade flows; while solid domestic and Iranian demand allowed Russian suppliers to maintain firm pricing despite Turkish buyers seeking $505–$510/t CFR, the broader market lost momentum by late May due to weakening Chinese futures and inflation pressures in ASEAN countries.

US Trade Representative (USTR) removed Brazilian pig iron from its tariff exemption list, subjecting the material to a 25% import tariff. This move creates significant uncertainty for Brazilian producers, particularly in Minas Gerais, which exported 2.47 million metric tons (mt) of pig iron worth $1.01 billion to the US in 2025, and an additional 644,700 mt worth $258 million in the first four months of 2026. With the city of Sete Lagoas historically shipping 85% of its production to the US, the new tariff barrier threatens to disrupt traditional trade flows. The imposition of these duties may force Brazilian suppliers to aggressively seek alternative markets, potentially leading to an oversupply and downward price pressure in other regions, while US buyers will likely face restricted supply and higher raw material costs.
