What Could Change if Middle East Aluminum Trade Reroutes—and Supply Becomes Substitutable

The closure of the Strait of Hormuz, ongoing escalation involving Iran, and attacks on regional energy infrastructure have fundamentally shifted the aluminum market from a supply-driven story to a logistics and risk driven one. Oil prices, freight rates, and insurance premiums have surged, pushing aluminum prices and physical premiums higher. While the Middle East accounts for roughly 9% of global aluminum supply, the real disruption lies in the system’s fragility: Aluminium Bahrain has cut around 19% of output and declared force majeure, Qatalum has shut down about 40% of capacity, and feedstock inventories across the region are estimated to last only around one month. Emergency alumina flows from Ma'aden offer temporary relief, but the bottleneck has clearly shifted from production to logistics.

In response, alternative routing scenarios are emerging, though neither offers a clean solution. One pathway is via Port of Sohar, allowing shipments to bypass the Strait of Hormuz. This route is relatively faster but constrained by infrastructure and capacity, requiring transshipment or inland transport from Gulf producers. Freight cost increases are not directly quoted as fixed percentages but are derived from observable market developments including surging war-risk insurance premiums, rerouting-driven delays, and emergency surcharges. Market indicators show marine insurance costs have risen sharply, with war-risk premiums increasing from around 0.25% pre-conflict to as high as 3% of vessel value, while tanker freight rates have surged amid reduced vessel availability and heightened risk.

In parallel, widespread rerouting and logistical disruptions have added substantial delays, with alternative routes and congestion extending delivery times by approximately 10–20 days in extreme cases, alongside additional costs from fuel consumption, port congestion, and transshipment requirements. Shipping lines have also introduced war-risk surcharges and suspended normal routes, further tightening capacity and increasing overall freight expenses. As a result, elevated logistics costs and delivery uncertainty are increasingly being transmitted into physical premiums, prompting buyers to reassess supply reliability.

Despite these workarounds, rerouting is ultimately a short-term mitigation rather than a true solution. The sustained increase in cost, transit time, and operational complexity erodes the Middle East’s traditional advantage as a low-cost, reliable aluminum supplier. As a result, the market is beginning to shift toward substitution strategies rather than simply absorbing delays. Primary aluminum supply is likely to diversify toward producers in China, India, Russia, and Canada, all of which offer more stable export channels under current conditions. At the same time, alumina flows may be redirected toward smelters outside the Middle East, particularly from Australia and Brazil, further tightening feedstock availability within the region and reinforcing production cuts.

Another key adjustment will come from the accelerated use of secondary aluminum. Scrap-based production becomes increasingly attractive in a high-energy, high-freight environment, as it reduces dependence on imported raw materials and long-distance logistics. This is likely to tighten scrap markets and raise secondary aluminum premiums, while also partially offsetting primary supply losses. Downstream consumers, including extrusion and rolling mills, are also expected to adapt by diversifying supplier bases, locking in long-term contracts outside the Middle East, and increasing inventory buffers, further reducing reliance on the region over time.

If disruptions persist beyond the immediate term, the implications become structural. In the short term (1–2 months), the market will experience acute tightness, sharp cost increases, and heavy reliance on rerouting and inventory drawdowns. Over the medium term (2–6 months), substitution will accelerate as alternative suppliers ramp up exports and buyers reconfigure supply chains. Beyond six months, a more permanent shift in global trade flows is likely, with the Middle East potentially losing market share and being repriced as a higher-risk, less reliable source of supply. Even if logistical routes stabilize, a geopolitical risk premium is likely to remain embedded in Middle Eastern aluminum.

Ultimately, while alternative routes through Oman or Saudi Arabia can keep material moving, they do so at a higher cost and with reduced efficiency. The more profound impact is the gradual erosion of confidence in the region’s reliability, prompting a rebalancing of global aluminum supply chains. What was once a stable, low-cost production hub risks becoming a marginal, risk-priced supplier, accelerating diversification across primary aluminum, alumina, and scrap markets worldwide.
