Middle East war reshapes global aluminum supply and demand pattern. Japan aluminum prices surged to the highest level in 11 years.

After the Iran war in the Middle East disrupted the global energy and commodity supply system, Japanese aluminum buyers have agreed to pay the highest premium/escalation in 11 years. This cost is likely to exacerbate the inflationary pressure faced by major manufacturing factories that use this core industrial metal. With shipping in the Strait of Hormuz still under substantial control by the Iranian military, and the ongoing escalation of Middle East conflicts, large-scale aluminum production cuts have occurred in the Middle East and Persian Gulf region, which accounts for approximately 10% of global aluminum supply. This includes Aluminium Bahrain announcing a large-scale reduction in production due to force majeure, and partial shutdown of Qatalum in Qatar. The strong rally in aluminum prices this year still has significant upward potential driven by structural tightness in supply. According to reports citing informed sources, some Japanese buyers have agreed to pay a premium/escalation of $350 per ton for shipments from global mining giant Rio Tinto Group in the second quarter, an 80% increase from the $195 per ton in the previous quarter, and even higher premiums of $353 per ton for South32 Ltd. shipments. Since negotiations or transactions are conducted privately, these informed sources requested anonymity. Statistics show that this is the highest quarterly escalation level since 2015, when the escalation size exceeded $400 per ton. According to reports, a spokesperson for South32 stated that this was a "price agreed upon through negotiations and consensus", but did not provide further details. Rio Tinto did not immediately respond to requests for comment. Informants said that some spot cargoes have even been transacted at higher escalations of $360 to $370 per ton. Given Japan's significant presence in the global industrial sector, the aluminum escalation in major Japanese ports is a closely watched reference indicator in the pricing of industrial metals and commodities in the Asian market. This cost is paid on top of the London Metal Exchange (LME) spot prices - the global benchmark metal prices. Aluminum, a lightweight industrial metal, has long been seen as a substitute for copper, especially in applications where cost, weight sensitivity, and relatively lenient electrical conductivity requirements are present. This substitution trend has been ongoing for over a decade and has accelerated in recent years due to concerns about resource security and the promotion of new energy industries. However, in high reliability, high power applications, copper remains irreplaceable. Aluminum is widely used in automotive bodies, certain consumer electronics, window frames, and beverage cans. Its price has risen over 10% on the London Metal Exchange this year. If the ongoing Middle East conflicts continue to worsen for another month, it is likely to continue to keep aluminum supply extremely tight, restricting production and shipping from the region (Middle East and Persian Gulf region), which accounts for 9% to 10% of global production. Beware of the "smoke bomb" of the US-initiated peace talks! The geopolitical situation in the Middle East may further deteriorate President Trump declared on social media on Thursday the postponement of the airstrike on Iranian energy facilities for another ten days, until 8 p.m. on April 6th (Eastern Time), which boosted global stock markets and commodity markets. However, the Pentagon has significantly increased troops in the Middle East and hasn't ruled out the possibility of ground forces striking Iran's Harc Island. The latest developments have made some investors remain highly cautious due to the potential escalation of conflicts over the weekend in the Middle East. President Trump openly urged Iran to take the ceasefire plan seriously and claimed that Iran urgently wants to reach an agreement. However, Iran has clearly stated that they have no formal plans for negotiations unless their core demands regarding Hormuz and future security guarantees are substantively met. Moreover, missile attacks between Israel and Iran continue to escalate, indicating that the prospects for "talks" or "anticipated US-Israeli-Iranian talks" transitioning to a substantive ceasefire are very distant. More importantly, what the market should not overlook is not the negotiating posture but the expanding radius of conflict. According to the latest reports, Houthi forces in Yemen have stated that they will join the support operations against Iran if needed, which may extend the risks from Hormuz to the Mandeb Strait and the Red Sea shipping routes. If Hormuz has already disrupted global energy flow, setting the Mandeb Strait on fire will impact not just oil but also broader aspects such as shipping, insurance, inventory cycles, and the global supply chain. In other words, the most dangerous aspect of the current Middle East geopolitical situation is not whether the fighting will continue, but whether it will turn into a "double energy chokepoint and double shipping route severe shock". Therefore, investors must be vigilant of the US's negotiation "smoke bomb". The current diplomatic signals are not enough to indicate a de-escalation of the situation, but rather appear to be a combination of pressure during wartime and efforts to buy time for mobilizing ground forces or the next round of large-scale airstrikes/missile attacks. For market asset pricing trends, this means that "having contact" should not be mistakenly extrapolated as "a quick ceasefire". In terms of macroeconomic judgments, this suggests that oil prices, commodities, liquefied natural gas, shipping, and inflation expectations should still retain significant premium space. If the market continues trading based on the "TACO-style" peace scenario, there is still the risk of further real backlash from the Middle East region being bombed. From Hormuz to Japanese ports: Middle East geopolitical conflicts are reshaping the global aluminum price curve For LME aluminum prices, market trading is no longer just on the basis of emotional bullish appeals, but rather on the real tightening of spot supply and the repricing of regional escalations - such as Japanese second-quarter aluminum premiums reaching new highs of $350-353 per ton in 11 years. Wall Street analysts overall remain bullish on aluminum prices for 2026, with reasons not solely concentrated on geopolitical conflicts, but also including the long-term demand for aluminum driven by energy transformation, the wave of AI data center constructions bringing structural support for aluminum demand and lightweight substitution, and long-term supply constraints on the supply side. Particularly, the ongoing strong demand for data centers has become a new growth engine for the copper market, with aluminum more as a "secondary beneficiary" of the effects of grid equipment and the rise in copper prices. The latest round of Middle East geopolitical conflicts has only pushed the already tight aluminum supply and demand balance further into a gap. In other words, aluminum is not primarily stimulated by single production cuts or export restrictions policies like nickel; it inherently has a strong industrial demand base, with the Iran war pushing the pricing of a long-term tight supply and demand logic more rapidly and intensely. Aluminum prices are expected to remain biased towards being easy to rise and difficult to fall for some time. Regional escalations and spot-side probabilities are likely to continue to be stronger than the LME flat base prices; however, if macro stagflation or short-term recession expectations significantly heat up, LME international aluminum prices may show more volatile and oscillating downward trends. With LME aluminum prices reaching their highest level since 2022 in March and the forward curve switching to spot premium mode, option implied volatility and European spot escalations are soaring in sync, indicating that the market no longer sees this shock as temporary noise but is already factoring in the expanding supply gap and the exacerbating spot tightness. Therefore, J.P. Morgan defines the current situation as a "supply-driven event horizon". J.P. Morgan analysts believe that if the shutdown spreads in the Middle East, there is the potential for a rapid impact on LME international aluminum prices hitting $4,000 per ton. The current LME aluminum prices are hovering around $3,260 per ton. J.P. Morgan believes that the danger on the supply side lies in the fact that production cuts have evolved from individual events to chain reactions. Qatalum has initiated controlled shutdowns, and Qatalum shareholders Hydro estimate that a full restart will take 6 to 12 months; Aluminium Bahrain (Alba) has announced that some contracts are due to force majeure; EGA has also confirmed delays in loading and shipping. More crucially, most aluminum smelters in the Middle East have oxide aluminum inventories only sufficient for 20 to 30 days, and shutting down smelters themselves takes several weeks. This means that in the coming weeks, more announcements of production cuts and even shutdowns are likely to occur. Due to the high dependence of aluminum smelting in the Middle East on imported alumina, and the fact that Hormuz simultaneously blocks both raw material inputs and finished product outputs, if the shipping bottleneck is not eased, the market will face not only short-term delivery delays but also months of production losses and higher scale of resuming production costs. J.P. Morgan emphasizes that the global aluminum market's buffer is now very thin, with LME inventories nearing lows, and a considerable portion of deliverable inventories not being preferred sources for western buyers. The high dependency of Europe and the US on imported aluminum from the Middle East, combined with the reduction of other smelting capacities in Europe and increased alternative supply costs due to US tariffs, is further intensifying the competition for aluminum metal supply. J.P. Morgan believes that the global aluminum market is approaching a re-pricing inflection point dominated by supply shocks, inadequate inventory, and accelerated spot reevaluation, with the potential for aluminum prices to quickly reach $4,000 driven by multiple factors.
