Copper prices stay firm near $13,642

Three-month copper on the London Metal Exchange rose 1% to $13,642 a metric ton on Friday, May 22, according to Reuters reporting carried by Business Recorder. The move kept the metal near the upper end of this year’s range even as traders weighed softer seasonal demand in China and uncertainty around U.S.-Iran diplomacy. London Metal Exchange data show copper remains a global benchmark for physical and hedging contracts, while exchange stock figures have become a central signal for near-term tightness. ### Why are traders still paying up for copper? Business Recorder, citing Reuters, said falling available inventories on the LME helped support prices despite expectations of seasonally weaker demand in China. That dynamic matters because copper prices tend to respond quickly when exchange stocks fall and nearby supply looks tighter. Westmetall data showed LME copper stocks at 391,900 tonnes on May 22, down from 394,675 tonnes on May 19. (brecorder.com) The decline was modest over that stretch, but it extended a pattern of lower warehouse stocks that traders have treated as evidence of a tighter physical market. ### How close is copper to this year’s highs? CNBC TV18 reported on May 22 that copper reached an all-time high of about $14,800 a tonne in the first quarter and said market forecasts were mostly skewed higher. (brecorder.com) At $13,642, the LME three-month contract remains below that peak but still well above levels seen earlier in the commodity’s long-run trading history. (westmetall.com) Business Recorder’s market file shows copper traded above $14,100 a tonne as recently as May 13 before pulling back in subsequent sessions. That sequence points to a market that has stayed elevated rather than one that has fully reversed. ### What are analysts and market participants pointing to? CNBC TV18 said the recent surge has been tied to supply concerns and stronger medium-term demand expectations. (cnbctv18.com) In a separate December report, the same outlet said demand from the energy transition and artificial intelligence sectors, together with supply constraints, could keep copper supported into 2026. (brecorder.com) The London Metal Exchange says its copper contract is the global reference price used in physical contracts and hedging transactions. That benchmark role means changes in LME stocks and pricing feed directly into procurement assumptions for cable, busbar, grounding and other copper-heavy equipment. ### Why does this matter for Chile projects in particular? Chile is advancing 13 copper projects worth $14.8 billion toward key 2026 milestones, according to Mining.com. (cnbctv18.com) That leaves engineering and construction teams exposed to the same copper market they are building around, especially on projects where conductor sizing, routing and equipment terminations are still moving late in design. (lme.com) For electrical work, the practical issue is lead times and quantity certainty. When copper prices stay volatile and exchange stocks are falling, late changes to conductor quantities or interface assumptions can force repricing, reorder cycles or delivery delays across cable and transformer-related packages. That conclusion is an inference from the price and inventory data and from the project pipeline in Chile. (mining.com) ### Where should readers watch next? The London Metal Exchange continues to publish current and historical copper prices and stock data on its copper market pages. In Chile, the next pressure points are the 2026 milestones for the country’s copper project pipeline, where developers and contractors will be watching whether high prices and tight inventories translate into procurement strain or faster investment decisions.
