Base Metals Supply Constraints Shape Early 2026 Outlook
By: Natalie Scott-Gray, Senior Metals Demand Analyst, EMEA and Asia region
Base metals markets are entering early 2026 with supply risk firmly back at the center of price formation. As of January 2026, policy-driven disruptions, refining constraints, and uneven mine output are shaping availability more than demand growth. The late-2025 rally has carried into the new year, but its sustainability increasingly depends on how quickly supply-side pressure eases. These insights are drawn directly from a primary-source interview assessing real-time conditions across global metals markets.
Natalie Scott-Gray, StoneX Senior Metals Analyst, has spent over a decade analysing supply chains across industrial metals with a focus on mine disruptions, refining economics, and trade flows. Her perspective is grounded in close monitoring of physical market signals, making her assessment particularly relevant as supply risks intersect with evolving policy decisions.
Key Themes
Supply-side risks remain elevated across copper, tin, and aluminum due to mining policy shifts and refining constraints.
Historically low refining and treatment charges are increasing vulnerability in refined metal availability.
Base Metals Supply Constraints Shape Early 2026 Pricing
Base metals supply risks are expected to remain prevalent in early 2026 as structural constraints persist across key markets. Natalie Scott-Gray notes that "supply side risks will remain prevalent in Q1, especially for metals such as copper, nickel and tin", underscoring how mining disruptions and regulatory shifts continue to limit output. These pressures are particularly acute where refining capacity is already stretched. Consequently, even modest demand recovery could translate into outsized price reactions.
Refining Economics Amplify Supply Vulnerability
Refining economics are emerging as a critical stress point for base metals availability. Scott-Gray highlights "historically low refining and treatment charges" as a factor increasing supply-side fragility following a year of mine disruptions. Lower charges reduce incentives for smelter throughput, compounding upstream supply losses. As a result, the base metals complex remains highly sensitive to any additional operational or policy shock.
