Copper prices experienced a decline following a turbulent weekend in the Middle East that cast uncertainty over peace negotiations between Washington and Tehran. The red metal fell 0.5 percent to settle at US$13,275 per metric ton on the London Metal Exchange, interrupting a four-week streak of gains as most industrial metals dropped in trading.
Geopolitical Uncertainty Weighs on Markets
The fragile ceasefire deadline between the United States and Iran approaches with increasing urgency. President Donald Trump stated in a Monday phone interview that he is unlikely to extend the two-week truce announced on April 7, which expires on Wednesday evening Washington time. While this deadline potentially buys more time for negotiations, Trump emphasized it would be highly improbable for him to prolong the ceasefire if no agreement is reached beforehand.
Further complicating matters, Iran remained ambiguous about its participation in additional peace talks, even after Trump noted that a delegation was en route to Pakistan. This uncertainty creates significant doubts about whether a diplomatic breakthrough can be achieved before the ceasefire deadline passes.
Strait of Hormuz Disruptions
Transits through the critical Strait of Hormuz have diminished to a mere trickle as Iran tightens control in retaliation for military strikes. The major risk for metals markets remains a prolonged closure of this vital waterway, which would amplify the energy shock already reverberating through the global economy.
Such a scenario could compel central bankers worldwide to adopt more hawkish monetary stances, potentially hitting global manufacturing sectors and damaging demand for industrial commodities across the board. The interconnected nature of global supply chains means disruptions in one region can have cascading effects throughout the world economy.
Chinese Demand Provides Market Support
Despite the geopolitical headwinds, copper prices are receiving some support from optimism surrounding demand in China, where inventories have declined rapidly in recent weeks. Stockpiles monitored by the Shanghai Futures Exchange have dropped by nearly 200,000 tons since reaching their peak on March 13 of this year.
Jia Zheng, trading manager at Suzhou Chuangyuan Harmony-Win Capital Management Co., noted that China is currently in its peak consumption season, with demand maintaining a high growth rate. According to Zheng, China's copper prices have begun to move away from the impact of the Middle East situation, suggesting domestic factors are increasingly driving market dynamics.
Aluminum Market Dynamics
Aluminum also slipped further on Monday, though the dynamics in this market differ significantly from other base metals. The Middle East conflict has forced smelter closures and production cuts across the region, creating upward pressure on prices despite the broader market decline.
The U.S. Midwest premium—the additional amount charged to deliver aluminum to that region above global benchmarks—rose to a fresh record of US$1.14 per pound on Monday, according to Fastmarkets data. This premium reflects the supply constraints and logistical challenges affecting aluminum distribution.
The International Aluminium Institute emphasized in an emailed statement that reopening the Strait of Hormuz is essential to allow producers to restock raw materials and export finished products that have been largely stranded at smelters. The organization noted this disruption is now having knock-on effects on supply chains extending as far as Australia, which supplies alumina to some Gulf smelters.
Aluminum production in Gulf countries dropped six percent to 15,963 tons per day in March, according to the institute, which acknowledged it doesn't yet have complete production figures for all member smelters in the region. Despite Monday's 0.2 percent decline to US$3,557.50 per ton on the LME, aluminum remains up 13 percent since the war broke out in late February.
Broader Commodity Market Movements
Oil prices climbed on Monday, reversing some of last week's steep declines as renewed fears for the global economy once again steered trade across commodities markets. The simultaneous movements in energy and industrial metals highlight how geopolitical tensions in the Middle East continue to influence multiple commodity sectors simultaneously.
The complex interplay between supply disruptions, geopolitical uncertainty, and regional demand variations creates a volatile trading environment for industrial metals. Market participants must navigate these competing forces as they assess price directions for copper, aluminum, and related commodities in the coming weeks.
