Key takeaways:
The escalating tensions between Iran and the US and Israel have already affected logistics around the Arabian Gulf, with regional aluminium producers heard to notify customers of port disruptions and delayed deliveries, while shipping lines have suspended operations in the region.
European market participants said a prolonged regional conflict would further exacerbate the structural deficit in the European aluminium market, which holds around a 20% import dependency on Middle Eastern supply, and raise regional premiums.
Gulf Cooperation Council members produced around 6.159 million tonnes of primary aluminium in 2025, around 8.35% of global supply, according to the International Aluminium Institute (IAI).
Market participants view GCC production as a key “swing supply” because the region’s smelters can export to Europe, the Americas and Asia whenever those markets offer the best premiums.
Fastmarkets’ daily aluminium P1020A premium, in-whs dup Rotterdam was $300-340 per tonne on Monday, up sharply from $280-320 per tonne day on day amid supply concerns from the Middle East.
“In the past, logistics issues in the Middle East have impacted more duty-unpaid premiums than duty-paid, putting more pressure on duty-unpaid if the conflict is stretching longer than anticipated,” a trader source said.
Before Monday’s increase, European duty‑unpaid premiums had already risen, driven by tight supply of non‑coal brands and strong competition for units from the US and Asia.
“Rotterdam premiums are definitely going higher, but it just depends on how long the conflict lasts — perhaps some people can wait a few weeks before buying,” a second trader said.
“At this moment, we would not buy P1020 as we have some stocks, but perhaps it is safer to buy soon rather than wait for when the premiums are much higher,” a European consumer said.
US President Donald Trump said on Monday March 2, that the US operation would last “four to five weeks,” adding that the country has the capability to continue far longer if needed.
As of March 2, market participants confirmed that regional producers had not declared force majeure.
Market participants also pointed to sharply higher block trades on the Chicago Mercantile Exchange’s Aluminium European Duty-Paid Premium cash-settled futures contract, which settles basis Fastmarkets, as a barometer for sentiment.
Second‑quarter 2026 strip buyers paid $420–440 per tonne on March 2, while third‑quarter 2026 buyers paid $405 per tonne, and market participants said short covering was also pushing futures higher.
Fastmarkets’ twice-weekly assessment of the aluminium P1020A premium, in-whs dp Rotterdam, was last assessed unchanged at $360-390 per tonne on Friday February 27 and will be next assessed on Tuesday March 3.
“The Rotterdam P1020 aluminium premium could react higher, with $400 per tonne as the first upside target and potentially as high as $420 per tonne,” Fastmarkets senior analyst Andy Farida said.
Fastmarkets’ assessment of the aluminium P1020A premium, ddp Midwest US stood at 104-107 cents per lb on March 2, up from 103-105 cents per lb on February 27.

In recent weeks, US Midwest premiums had remained flat but elevated at 103-105 cents per lb over February 18-27, with expectations of further upside, amid ongoing reluctance to ship to the US amid the tariff uncertainty, despite relatively muted spot demand.
“Looking to the US, with 50% tariffs already in place, any reduced supply from the Middle East will likely result in further inventory drawdowns, again increasing regional premiums, and near-term volatility,” Natalie Scott-Gray, senior metals demand analyst at StoneX, said.
Scott‑Gray said reduced Middle Eastern supply could also hit Japan and South Korea, forcing them to compete more aggressively for units from Canada, India or Africa. This shift would increase pressure on European buyers.
Market participants could not confirm reports that suppliers pulled recent offers at $220 and $250 per tonne for aluminium deliveries to the main Japanese ports (MJP) in the second quarter of 2026, after the conflict in the Arabian Gulf escalated.
European aluminium billet markets grew more uncertain on March 2 on concerns of offshore supply tightening further following the closure of the Strait of Hormuz.
“The impact on European premiums for billet, slab and primary foundry alloy [PFA] could be huge if major producers like EGA and Alba are affected.”
European consumers may have to turn to secondary billet producers for volumes, according to a fourth trader, who noted that these billet producers would, in turn, have to procure and remelt P1020 to produce said billet.
A European billet producer said they would look to offer billet “above $700 per tonne” if disruptions persist, noting that extruders were calling to ask for spot volumes.
Billet market participants reported mostly discussions rather than firm negotiations amid the broader uncertainty, but said they expected further premium increases, with trading likely to pick up toward the end of the week once markets have had time to react.
“As long as a cheaper Middle Eastern billet is in the game, secondary European producers will not produce. But now? I am sure they get requests,” another trader added that $700 per tonne DDP Europe was likely to be at the lower end of current expectations for re‑smelters. “For example, if they have to buy primary aluminium at $500 per tonne DDP and then add about $250 per tonne in conversion costs. They end up with an EU re‑melt billet number closer to $750 per tonne.”
European billet premiums have been rising steadily in 2026, following the introduction of the Carbon Border Adjustment Mechanism (CBAM) and the reversion of the import duty to 6% from 4% on January 1.
Fastmarkets assessed the aluminium 6063 extrusion billet premium, ddp North Germany (Ruhr region) at $560-600 per tonne on February 27, increasing from $490-530 per tonne on January 2.
Fears of disruption at the Strait of Hormuz, alongside potential damage to Iranian aluminium smelting capacity, weighed on sentiment among some market participants.
“The loss of smelting capacity in Iran would for sure inject some alumina back in the market,” a sixth trader said.
“Take into account smelters on the west side of Hormuz. They’re theoretically the bigger game, with a lot of smelting and not much refining. This would be bearish for alumina and bullish for aluminium,” they said.
Fastmarkets’ daily assessment of the alumina index, fob Australia, was $300.50 per tonne on Monday, down from $303.44 per tonne on Friday.
According to Fastmarkets’ research team, Iranian smelters consume an estimated 1.2 million-1.4 million tonnes per year of smelter-grade alumina, with Indian refineries notably providing a significant amount.
Most of this material enters the region through the Strait of Hormuz.
“If the conflict lasts four to five weeks, then will the Middle Eastern producers have enough alumina, or petcoke, or coal tar pitch and other raw materials to produce aluminium?” a seventh trader told Fastmarkets, noting that one regional producer had signaled to customers that it held many weeks’ worth of raw materials to produce aluminium.
Another trader noted that regional smelters may look to prolong their existing alumina stocks and reduce production capacity utilization levels.
Some market participants argued that alumina prices and supply-and-demand fundamentals are relatively stable for now despite the conflict and disruption, citing a lack of market activity.
“Right now, everybody’s waiting and seeing. Nothing’s really happened, although the sentiment is changing based on this,” a ninth trader said.
Market participants noted that producers unable to sell to the Middle East have the option to divert their cargoes to other buyers.
“I don’t see anyone loading a ship in the next one or two weeks and pointing to the Middle East,” the ninth trader said. “You could push the laycan back as far as possible for the Middle East and hope for a resolution, or you can call any smelter that can help you and hope they’ll take an early laycan.”
