Stock Market Impact: Goldman Sachs forecasts a materially tighter copper market outside the United States through 2026‑27, driven by a 1.5% drop in global mine supply (~350,000 tons). This scarcity is expected to support LME copper prices, potentially pushing them above $14,000 per ton in the second half of 2026 if a U.S. tariff is introduced, or keeping them near $12,800 per ton if no tariff materialises.
Listed Companies and Sectors: The bank recommends two copper equities as buys:
Lundin Mining Ltd – rated a buy on a relative valuation of roughly 1× price‑to‑net‑asset‑value versus peers at 1.5‑2×. Copper now accounts for 85% of Lundin’s total revenue, the highest exposure in the sector. Operational performance remains strong with continued production and cost discipline. Growth catalysts include the Vicuna RIGI approval and a final investment decision expected late 2026. Recent Q1‑2026 results showed a robust adjusted EBITDA margin and strong cash‑flow generation.
Antofagasta plc – also rated a buy, highlighted for its copper‑gold leverage and scarcity premium as a pure European copper‑gold equity. The portfolio is anchored by the Centinela and Pelambres mines, which together represent about 80% of current output and are projected to drive roughly 95% of production growth over the decade. The Centinela expansion, especially the second concentrator, is progressing as planned. Analyst coverage has seen downgrades to Hold (Berenberg), Underperform (RBC Capital), and Neutral (JPMorgan).
Investment Flows: Strong U.S. copper imports in the first half of 2026 are pulling metal out of the ex‑U.S. system. U.S. inventories are expected to increase by approximately 900,000 tons in 2026, reaching about 1.8 million tons by year‑end, which will deepen the ex‑U.S. deficit to roughly 640,000 tons in 2026 and 170,000 tons in 2027.
Interest Rates, Inflation, and Liquidity: No direct references to monetary policy, interest rates, or inflation are made in the article.
Fiscal or Monetary Policy: The key policy variable is the pending U.S. tariff decision expected in June 2026. A January 2027 tariff introduction would likely accelerate U.S. imports, tightening the ex‑U.S. market further. Conversely, a definitive no‑tariff outcome could reduce the ex‑U.S. deficit and potentially flip the 2027 balance into surplus.
