[SMM Analysis] Persian Gulf Shutdown? The Impact of the U.S.-Iran Conflict on Global Steel Trade On February 28, 2026, the conflict between the United States and Iran escalated into a full-scale outbreak, causing a sudden spike in Middle Eastern geopolitical tensions. As a global chokepoint for energy and bulk commodity maritime transport, the Strait of Hormuz has seen shipping disrupted and routes tightened, directly impacting the nerves of the global supply chain. This "Golden Waterway" is not only a lifeline for oil but also a critical strategic corridor for the global steel import and export trade . Once passage is restricted, it will deliver a comprehensive shock to the international steel trade landscape. Amidst the turmoil of war, what disruptions and restructuring will the global steel trade face? SMM's latest research provides an in-depth analysis. In the short term, the U.S.-Iran conflict poses a risk of stalling steel imports and exports in the Persian Gulf region, putting pressure on China's steel exports. Multiple disruptions along Gulf shipping routes have caused significant delays in exporters' orders. According to SMM research, the current Middle East situation has disrupted multiple ports in the Gulf region. Bahrain has suspended port activities, including pilotage services. Jebel Ali Port has halted all operations due to a fire caused by intercepting airstrike debris. Qatar's Ras Laffan and Messaid ports remain operational but with reduced traffic, GPS signal interference, and the government closure of its airspace. Similarly, new orders and shipments for Chinese exporters have also been significantly hindered. Data Source:SMM Impact Assessment of Core Ports within the Strait of Hormuz Should a physical blockade occur at this strategic chokepoint, the five most directly affected key inner-bay ports experiencing “instant logistics paralysis” would be: Port of Bandar Abbas, Port of Khomeini, Port of Jebel Ali, Port of Khalifa, and King Abdullah Port. Simultaneously, a Strait blockade would threaten to disrupt approximately 10% of global seaborne steel trade (primarily semi-finished products and specialty ores) . Iran's production of direct reduced iron (DRI) also holds significant weight in global supply; any disruption could drive up costs for electric arc furnace steelmaking in the Middle East. Data Source: SMM Ferrous Metal Shipping After the blockade, will goods become completely impossible to transport? While maritime routes will indeed come to a near standstill, the flow of goods won't cease entirely. It will simply become extremely costly, slow, and require complex overland transshipment. For instance, strategic alternative ports outside the strait include Sohar Port, Chabahar Port, and Gwadar Port. Data Source: Compiled by SMM based on publicly available information Trade Chokehold Triggered by Insurance Withdrawals Equally severe as the strait blockade is the withdrawal of war risk insurance. Marine insurers Skuld and Gard have announced they will cancel war risk coverage due to escalating tensions in the Middle East. Local feedback from the UAE indicates most insurers refuse to underwrite war risk insurance for the Red Sea. This means traders must bear multiple uncontrollable factors and assume all consequences, which will significantly impact new orders. Summary: The Hormuz Crisis's “Hedging Effect” on China's Steel Market Leads to Short-Term Export Pressure Short-Term Negative Impact (Suppression of Demand and Logistics): The sudden halt in Gulf shipping routes will cause China's total exports to Middle Eastern countries like Saudi Arabia and the UAE to plummet dramatically. Export disruptions may even force resources to flow back into the domestic market, intensifying supply pressure and exerting downward pressure on steel prices. Data Source: SMM, GACC Mid-term outlook: As a major steel supplier, Iran's halted exports will trigger tightening supply of steel billets in Southeast and South Asia. From Construction to Industry: Iran's Steel Export Structure Transformation and the Peak Era Dominated by “Billet” According to data released by the Iranian Steel Producers Association (ISPA), 2025 marked the “peak era” for Iran's steel exports, with its export structure exhibiting an extremely aggressive trend: ① Absolute Dominance of Semi-Finished Products: From March to December 2025, Iran's billet exports reached 4.58 million tons (+37.7% YoY), while slab exports hit 1.54 million tons (+44.6% YoY). This confirms the earlier observation that the current strait blockade will trigger significant “slab panic” among downstream steel mills in Southeast Asia and the Middle East. ② Structural Leap in Flat Products: Finished flat product exports surged from 307,000 tons in the same period last year to 1.03 million tons. Notably, the significant increase in hot-rolled coil (867,000 tons) and coated steel (up 76.7% YoY) indicates Iran's gradual transition from a “construction steel supplier” to an “industrial raw material supplier.” ③ Weakness and contraction in long products: In contrast, exports of finished long products (rebar, wire rod) declined by 9.9%, while structural steel exports plummeted by 27.7%. This trend of “reducing long products while increasing flat products” has, against the backdrop of stalled infrastructure projects, actually heightened the risk of inventory buildup for finished goods. Data Source: ISPA Mid-term positive factors: Cost and substitution support Iran's steel export shortfall of nearly 11 million tons will trigger regional supply tightness, forcing some Southeast Asian and South Asian buyers to shift procurement to China, creating “substitution-driven incremental demand.” Simultaneously, rising crude oil prices may push up costs across the entire industrial chain, providing bottom-up support for steel prices. Although logistics disruptions and project suspensions will suppress export performance in the short term, the reshuffling of the global supply landscape is expected to partially offset the negative impact. Chinese steel may play a key role in filling the global gap. Long-term outlook: Iran's ceasefire may temporarily impact the global steel market Hoarding effect under blockade: Iran's sharply rising mill and port inventory pressures According to the latest global steel statistics report released by the World Steel Association (WSA), Iran's cumulative crude steel production reached 31.8 million tons in 2025, marking a year-on-year increase of approximately 1.4% compared to 2024 and solidifying its position as the world's tenth-largest steel producer. In December 2025, Iran's monthly crude steel output hit 3 million tons, a significant year-on-year increase of 16.2%. This indicates that Iranian steel mills were operating at peak capacity just before the conflict erupted. In January 2026, its crude steel output reached approximately 2.6 million tons, marking a 15.1% year-on-year increase. Against the backdrop of a 6.5% year-on-year decline in global crude steel production during January, Iran demonstrated an “independent trend.” According to SMM research, the high production levels from earlier periods have led to severe inventory backlogs at domestic steel mills. The logistics blockade that began in late February prevented the full shipment of steel produced during this high-output phase out of the Persian Gulf. Consequently, ports and mill warehouses are now stockpiling large quantities of slabs and billets originally intended for export. Once the situation eases, this “low-priced inventory” could flood the market at dumping prices. However, considering Iran's post-ceasefire reconstruction needs and the actual release of these supplies, SMM will continue to monitor developments closely.

[Galvanising enterprise WoW fewer resumed work, operating rates fell from pre-holiday]: Galvanising industry operating rate was 6.84% this week, down 6.2 percentage points WoW from pre-holiday. Raw material side, zinc prices mainly fluctuated this week, but most downstream were still on holiday and had not resumed work, transportation was gradually recovering, enterprises mainly consumed inventory, galvanising enterprise zinc ingot inventory slightly decreased.

[SMM Titanium Weekly Review: Titanium Market Diverged Post-Holiday, Titanium Dioxide Led Gains While Titanium Products Steadily Recovered] This week, the titanium industry chain showed divergent performance. Titanium concentrate operated steadily, with mines awaiting new March orders. Sentiment for titanium dioxide price hikes remained strong, led by the chloride process; high sulphuric acid costs supported expectations for price increases, though actual implementation still depends on demand follow-through. Titanium slag was in the doldrums, under cost pressure, with prices consolidating at the bottom. Sponge titanium saw weak supply and demand, prices held steady, and future performance relies on downstream restocking to boost recovery. The titanium products market recovered steadily, mainly driven by rigid demand restocking, and is expected to stabilize next week.

After the Chinese New Year holiday, premiums in Tianjin remained at a discount throughout February. How will premiums and discounts move going forward?

According to SMM research, most galvanising enterprises resumed production between the tenth day (February 26) and the sixteenth day (March 4) of the first lunar month. Small and medium-sized enterprises generally resumed operations after the Lantern Festival (March 2), with an average holiday duration of around 21 days.

During the week, the zinc ingot market in Guangdong underwent a contract rollover, with spot quotations officially switching from the 2603 contract to the 2604 contract. Against the backdrop of the SHFE zinc market maintaining a Contango structure, spot premiums and discounts for zinc ingots in Guangdong continued their downward trend after the rollover, further declining from -80 yuan/mt before the rollover to -125 yuan/mt today, highlighting persistent short-term downward pressure.

[SMM Analysis] Holiday Stability in Overseas Prices, Divergent Trading Performance HRC prices in Thailand and Malaysia mostly held steady. As the holidays largely coincided with those in the domestic market and shipments were affected by the Chinese New Year, overall transaction activity remained relatively weak. The galvanizing market in Thailand performed moderately, but due to low-priced resources capturing market share, downstream shipments were somewhat impacted, leaving limited room for price increases. Influenced by factors such as Ramadan, HRC trading in Indonesia also trended toward mediocrity, while overseas export offers remained stable amid a wait-and-see stance. However, supported by government policies promoting increased use of domestically produced steel in the local shipbuilding industry, medium and long-term demand for sheets & plates in Indonesia is expected to remain relatively optimistic.The Black Sea market recently exhibited overall calm, with FOB offers for HRC exports pulling back slightly compared to pre-holiday levels. Although some routine transactions were concluded, overall market activity remained sluggish. Despite tight spot supply in the domestic Indian HRC market, it remains range-bound due to weak overall procurement demand, lacking momentum for price increases. Turkish HRC export offers have seen slight increases, following the price hike trend among European producers. European and US markets face strong policy and cost disruptions: although the US Supreme Court overturned some previously imposed tariffs by the president, the subsequent announcement of new global tariffs of up to 15% has sharply heightened market risk aversion. In European markets such as Italy, steel mills are leading ex-factory price increases against a backdrop of tight spot supply.

[Galvanising enterprises mostly on holiday, operating rates drop significantly]: This week, the operating rate of the galvanizing industry was 16.25%, down 22.35 percentage points WoW. From the raw material side, zinc prices mainly fluctuated this week, but most downstream enterprises were on holiday, with pricing being the main activity and fewer cargo pick-ups. However, large plants had basically received long-term contract goods by the beginning of the week, and zinc ingot inventories at galvanising enterprises increased slightly.

【Why Does the Zinc Slag Coefficient Remain High?】According to SMM, the overall zinc slag coefficient remained high in February. What are the reasons behind this? How will it perform in the future? ...

[Galvanising Enterprise Holidays Increase, Operating Rates Drop Significantly]: This week, the operating rate in the galvanizing industry was 38.60%, down 7.49 percentage points WoW. Raw material side, zinc prices pulled back slightly this week, but most downstream producers were on holiday, with only a small amount of spot pricing and cargo pick-up. Large plants gradually received long-term contract shipments, and zinc ingot inventories at galvanizing enterprises increased.
