Barlow’s Research Roundup: Obscure chemical shortage threatens global copper supply
A shortage of sulphuric acid, exacerbated by China's upcoming export ban, threatens 20% of global copper production, particularly affecting leaching operations in Chile and the DRC. Ivanhoe Mines is positioned as a beneficiary due to its acid-producing smelter, while Capstone and Lundin may face cost pressures. Meanwhile, defense stocks declined despite strong backlogs, as investors react to execution issues and a lack of near-term catalysts.
- ▪China will halt sulphuric acid exports starting May 2026 to prioritize domestic fertilizer and battery production, threatening global copper output.
- ▪Sulphuric acid prices have reached $1,000/tonne, impacting leaching operations that account for 20% of global copper supply.
- ▪Ivanhoe Mines' Kamoa-Kakula smelter produces 1,200tpd of acid, potentially generating over $400 million in annual byproduct revenue.
- ▪Defense stocks including Lockheed Martin and Northrop Grumman declined sharply despite growing order backlogs, as markets focus on margin and execution concerns.
- ▪Analysts warn that optimistic 2026 profit growth forecasts of 17%–20% may be unsustainable given weak GDP correlation and concentrated revisions.
