Weather & Natural Disasters: Market Impact — May 26, 2026

Chilean Earthquake Threatens Global Copper Supply

On May 25, 2026, a significant earthquake with a magnitude of 6.9 struck 29 km east-northeast of Calama, Chile, at a depth of 109 km. This event occurred in the heart of the Chilean Copper Belt, a region responsible for approximately 25% of the world's copper output. The immediate impact on copper markets is substantial, with potential disruptions to mining operations and supply chains.

• Market Impact: The earthquake poses a significant risk to global copper supply, potentially driving prices higher as markets react to potential shortages.
• Supply Chain Concerns: Any prolonged disruption in Chile could exacerbate existing supply chain issues, particularly affecting industries reliant on copper, such as electronics and construction.
• Price Movement: Investors should anticipate volatility in copper prices, with potential upward pressure as the market assesses the extent of the damage and operational disruptions.

Indonesian Earthquake Impacts Nickel Supply Chain

Also on May 25, 2026, a magnitude 5.6 earthquake occurred 113 km east-southeast of Bitung, Indonesia, at a depth of 31.1 km. This region is part of the Indonesian Nickel Belt, the world's leading nickel-producing area, crucial for the electric vehicle (EV) battery supply chain.

• Market Impact: The earthquake could disrupt nickel production, affecting the supply chain for EV batteries and potentially leading to increased nickel prices.
• EV Industry Concerns: Any supply constraints in nickel could have ripple effects on the EV industry, potentially slowing production and increasing costs.
• Price Movement: Nickel prices may experience upward pressure as the market evaluates the impact on production and supply continuity.

Looking ahead, the market will closely monitor the operational status of mines in both Chile and Indonesia. Key catalysts include updates from mining companies on damage assessments and timelines for resuming full production. Confirmation of significant disruptions could lead to sustained price increases in both copper and nickel markets, while swift recovery efforts might mitigate some of the immediate price pressures. Investors should pay attention to official statements from major mining firms and local authorities for guidance on the evolving situation.
