Anglo American, Glencore and other FTSE miners rebound despite Trump copper tariff

FTSE mining majors, including Anglo American and Glencore, rebounded significantly on Thursday, with 3%+ gains, despite President Trump confirming a 50% copper tariff effective August 1st, alongside similar tariffs for Brazil. This 'risk-on' sentiment coincided with US copper futures surging 13% to record highs, although spot copper prices fell, creating a notable divergence. Analysts suggest the tariff's effectiveness in boosting US domestic production is uncertain, potentially leading to higher US prices or a redirection of global supply, which explains the current market dynamics.

Analysis

Major FTSE-listed mining companies, including Anglo American and Glencore, experienced a significant rebound with gains exceeding 3%, reversing the prior day's losses despite the confirmation of a 50% US tariff on copper effective August 1. This risk-on sentiment was directly fueled by an unprecedented 13% single-day surge in US copper futures, which propelled the contract to record highs. However, a critical divergence has emerged, as the price of spot copper simultaneously declined. This bifurcation is attributed to uncertainty regarding the tariff's ultimate effect; it could either inflate copper prices within the US by taxing imports or, conversely, depress prices outside the US if global shipments are diverted to other markets, thereby increasing ex-US supply. The market appears to have anticipated this policy, evidenced by record volumes of copper being shipped to the US in recent months, complicating the forward outlook for supply and pricing dynamics.

Key Decisions for Investors

• Investors should closely monitor the widening divergence between US copper futures and global spot prices, as this gap is a key indicator of the tariff's real-world impact on regional supply and profitability.
• While the immediate reaction in mining equities is positive, driven by the futures rally, it may be prudent to consider the medium-term risk that a significant diversion of copper supply away from the US could depress global prices and negatively impact producer revenues.
• Pay close attention to trade flow data and inventory levels in the US versus other major markets after the August 1st implementation, as these metrics will provide the first concrete evidence of whether the tariff is creating a US-specific shortage or simply rerouting global supply chains.
