ROI-War? What is war? Aluminium's Gulf disruption premium vanishes: Andy Home

You wouldn't guess it by the price of aluminium.

Two damaged Gulf smelters, and the resulting?logistical constraints at other smelters have already created a 2 million metric ton gap in the global supply chains.

After surging to a 4-year high of $3,787.50 per tonne in early June, London Metal Exchange's (LME) 3-month aluminium now trades around $3,170 a tonne, exactly where it traded before the United States launched its "Operation?Fury", a joint strike with Israel against Iran, on February 28.

Where did the war premium end up?

Is the market right in being so'relaxed' about?the unprecedented shortage of a metal that both Washington and Brussels consider to be a critical one?

What is a SPEEDY Recovery?

After an Iranian missile attack, the market was encouraged by the progress that Emirates Global Aluminium made in repairing and reactivating their Al Taweelah plant.

As of July 2, the company has restarted 89 out of 1,262 smelter cells.

Qatar Aluminium, which is still operating at 60% capacity, continues to be affected by the Iranian attacks.

According to the International Aluminium Institute, Gulf production fell by 20% during the first half this year. Since the start of hostilities, smelter production has dropped by more than 2 million tonnes annually.

Even if you assume that things will return to normal, it could be several months before the full recovery is complete.

This is becoming increasingly unlikely, as the United States continues its bombing campaign against Iran and Tehran tightens the chokehold it has on the Strait of Hormuz. The Houthis, who are aligned with Iran's government, have also begun to enforce their own Red Sea blockade.

CHINA RAISES EXPORT VOLUMES

The unexpected calm in the market over the past few days is due to a growing belief that even if the Gulf metal loss continues, it can be "offset" by increased exports from China or Indonesia.

China's aluminum smelters enjoy high profit margins due to the combination low alumina prices and high metals. According to consultancy AZ Global, capacity utilisation is close to 99%.

World Bureau of Metal Statistics, which collects official data on customs, reports that exports of semi-manufactured aluminum products like bars, rods, and tubes grew by 10% year-on-year during the first five months of the 2026. The 595,000 tonnes of aluminium shipped in May was the highest number since November 2024.

China's exports of primary and alloy products are not equivalent to the production lost in the Gulf. However, they can help restore the market balance by suppressing Western demands.

China's exports are in direct competition with the West which has already implemented multiple trade protections measures.

INDONESIA RISING

Indonesia is another option.

A Chinese investment boom has led to the rapid rise of China as a primary aluminium supplier.

The Hua Chin Smelter, which produces 480,000 tons of steel per year, is a joint venture between Tsingshan Holding Group (THG) and Huafon Group. It ramped up production last year, and in May, it applied to register the "HCAI" trademark with the LME.

Alamtri Resources Indonesia is another newcomer that has built a plant of similar size and began exporting its products in June.

According to Greg Wittbecker of Wittsend Commodity Advisors, the project pipeline includes 11 new smelters, with a combined annual production of 13,000,000 tons.

WBMS reports that Indonesian exports of primary metal jumped from 155,000 ton in 2024, to 511,000 ton in 2025. They also grew by 58% in the first five month of this year.

It is easy to understand why the aluminium industry has relaxed its stance on the impact of the Gulf production.

Stock ABSorbers

The apparent resilience of the aluminum supply chain is also a cause for concern, as shown by Indonesia's trade flow.

Last year, the main destination for exports was China with 40% of all shipments. South Korea, Vietnam and Japan followed closely behind with 16%, and 12% respectively.

Exports to Europe were substantial, especially in the fourth quarter.

Indonesian smelters sent 15,000 tons of iron ore to Spain, 14,800 to Croatia, 11000 to Bulgaria, 5,500 to Italy, and 5500 to the United Kingdom. A further 39,000 tons was sent to Turkey.

It seems that this was a collective stock building exercise in anticipation of the implementation of Europe's Carbon Border adjustment Mechanism (CBAM), which is scheduled to begin at the beginning of this year.

The new generation of plants is powered by coal and therefore costs for CBAM are higher.

The build-up of inventory has played a major secondary role in reducing the impact of Gulf disruption.

The biggest question is, however, how much money has been withdrawn and when it will need to be replenished?

While the war premium has disappeared from the LME's futures market it still remains in the CME physical premium contracts.

Since the beginning of the U.S./Israeli war against Iran, the European duty-unpaid rate has increased by 65%. The Japanese duty-unpaid premium has doubled.

LME traders are sanguine about the worsening situation in Gulf but their counterparts on the ground don't appear to be so certain.
