Key Points:
- LME aluminum futures plunged 3.2 percent to $3,422.50, hitting their lowest level since late March.
- Easing Middle East tensions and the expected reopening of the Strait of Hormuz collapsed supply risk premiums.
- Goldman Sachs downgraded China’s top producer, Chalco, to Sell, triggering an 8.8 percent stock drop.
- Stubbornly weak Chinese industrial data and a manufacturing off-season added heavy downward pressure.
Aluminum Extends Slump at the start of the week, tumbling to its lowest pricing level in more than two months as a powerful combination of weak Chinese industrial data and geopolitical easing in the Middle East dampens market sentiment. On the London Metal Exchange (LME), the benchmark three-month aluminum contract plunged by 3.2% to settle at $3,422.50 per metric ton, after briefly hitting an intraday low of $3,408. This sharp price correction marks a dramatic unwinding of the geopolitical risk premiums and physical scarcity fears that had pushed the light metal to multi-year highs just two weeks earlier.
The preliminary peace agreement between the United States and Iran primarily drove the market’s sudden downward trajectory. The draft treaty plans an immediate end to the military conflict and authorizes the complete, toll-free reopening of the strategic Strait of Hormuz to commercial shipping. The Persian Gulf represents a significant hub for global metallurgy, accounting for approximately 10% of the world’s primary aluminum output. Investors expect the immediate reopening of the shipping lanes to allow regional smelters—which suffered severe operational disruptions and physical damage during the war—to quickly resume their global export schedules.
This rapid price decline has baffled some commodities traders because it completely defies traditional market logic by occurring alongside a persistent drop in public warehouse inventories. In most metals markets, declining stock levels signal physical scarcity, which normally pushes prices higher. However, LME aluminum inventories continued to contract even as prices slumped. Industry analysts explain that the market is currently pricing in the rapid return of highly substantial “invisible” or privately held off-exchange stockpiles from the Middle East, rendering the decline in publicly visible warehouse stocks temporarily irrelevant.
While supply-side fears are fading, demand-side pressures in China—the world’s largest producer and consumer of the light metal—are adding significant downward pressure to prices. Fresh industrial data shows that China’s domestic manufacturing sector is entering a soft off-season, with downstream processing factories actively cutting their raw material purchases. For instance, data from the China Motorcycle Chamber of Commerce revealed that domestic motorcycle production and sales in May pulled back by 2.67% and 5.28% month-on-month, respectively. This industrial cooling suggests that China’s domestic market can no longer absorb the massive, record-breaking output of its local smelters, which have been running beyond capacity.
To make matters worse for the industrial metals sector, prominent Wall Street financial institutions have begun taking an increasingly bearish view on major producers. Goldman Sachs officially downgraded Aluminum Corp of China, the state-run giant known as Chalco, from “Neutral” to “Sell”. The brokerage slashed its twelve-month price target on Chalco’s Hong Kong-listed shares by a massive 40%, dropping the target to HK$7.50 from a previous HK$12.50. Analysts explained that the emergence of new, alternative aluminum supply sources globally—combined with a softer outlook for the light metal—presents a highly challenging profitability environment for the Chinese giant.
Public trading data further amplified this selling pressure, showing that Chalco recently registered one of the largest single-day Hong Kong Stock Connect ownership decreases among all listed companies. This massive, coordinated exit by mainland and international investors shows that global funds are actively reducing their exposure to base metals producers as the commodities supercycle cools off.
The sudden, multi-week price retreat represents a complete reversal of the market conditions that dominated early June. On June 2, benchmark LME aluminum futures had jumped to a nearly four-year high of $3,855 per tonne, fueled by a severe, ex-China physical supply crisis. The Middle East war had physically damaged key regional smelting operations, including Emirates Global Aluminium’s Al Taweelah plant in Abu Dhabi, which technicians estimated would take at least a year to fully repair following a series of missile strikes. This extensive damage had forced Western buyers to scramble for alternative Chinese exports, driving regional premium spreads to record highs.
Ultimately, the sharp slump in aluminum prices demonstrates that the global commodities market is undergoing a rapid, supply-side rebalancing. While months of military conflict and shipping blockades had restricted physical supply and pushed prices to historic highs, the sudden prospect of peace has successfully defused the energy crisis. As the formal signing ceremony in Switzerland approaches, the eventual reopening of the Strait of Hormuz will provide the supply-side certainty needed to keep the global recovery on track. For both industrial manufacturers and commodities investors, this historic de-escalation offers a vital, long-awaited safety margin in a highly volatile economic landscape.
