Supply disruptions tighten copper market
Several unforeseen events curbed copper output in 2025. In May, flooding halted operations at Ivanhoe Mines’ Kamoa-Kakula complex in the Democratic Republic of Congo, one of the world’s largest copper producers. Later in the year, a tunnel collapse at a key Chilean site and a mudslide affecting Freeport-McMoRan’s Grasberg mine in Indonesia further reduced global supply. These incidents coincided with the accelerating build-out of data centers and grid upgrades, intensifying the imbalance between available metal and physical demand.
The combined impact of the outages tightened inventories on major exchanges and contributed to the 34% annual price increase. Market participants reported longer delivery times for concentrate and refined cathode, pushing consumers to secure material at higher spot premiums.
Lithium market reacts to Chinese suspension
Lithium prices spiked after the Chinese government temporarily suspended operations at one of the principal mining sites used by battery manufacturer CATL. The halt, enacted to review environmental compliance, removed significant tonnage from near-term supply chains. With electric-vehicle sales rising and stationary storage installations expanding, the supply interruption led to a 30% year-to-date price gain for the battery metal.
Producers in Australia and South America indicated plans to accelerate capacity additions, but most new volumes will not arrive until late 2026 or beyond, leaving buyers exposed to short-term volatility.
Energy prices constrain aluminum and steel output
Aluminum and steel markets faced a different set of challenges. Smelting and refining these metals require large amounts of energy, and power costs climbed as the war in Ukraine disrupted natural-gas flows and AI-driven data-center expansion increased electricity demand in several regions. Higher energy prices forced some European and Asian smelters to reduce operating rates, limiting supply and supporting aluminum’s 14% rise.
China, the world’s largest aluminum producer, approached its government-mandated capacity ceiling during the year, constraining fresh output despite domestic consumption growth. In steel, rising costs for coking coal and electricity raised production expenses, contributing to a 27% jump in hot-rolled coil prices.
Precious metals driven by safe-haven demand
Parallel to the industrial-metal rally, gold and silver benefited from a different dynamic. Investors turned to the precious metals as geopolitical tensions and uncertain economic data encouraged a flight to perceived safety. Prices for both metals set new records, capping one of their strongest years on record. Though not linked directly to the AI supply chain or energy transition, gold and silver’s performance provided an additional signal of the broader commodities uptrend in 2025.
Outlook shaped by demand and supply factors
Market analysts noted that demand related to emerging technologies and decarbonization initiatives continued to intersect with unpredictable supply conditions throughout the year. Environmental incidents at major mines, regulatory interventions and energy-market volatility combined to tighten inventories across several metals simultaneously. With infrastructure projects and advanced-manufacturing investments still in progress, participants remained attentive to further disruptions that could influence pricing into 2026.
