Antofagasta and Anglo in focus as leading bank urges selectivity in copper rally

UBS recommends selective investment in copper producers, favoring Antofagasta and Anglo American due to their leverage to long-term demand and constrained supply despite a recent copper price rally. The bank cautions that short-term copper market strength driven by speculative flows and trade distortions may soften as these factors ease and mine supply remains under pressure, with Q1 production growth limited. However, UBS maintains a positive long-term outlook, citing structural demand from electrification and renewables, while also noting potential challenges to refined output growth due to tightening feedstock.

Analysis

UBS advises a selective approach to copper producers, highlighting Antofagasta PLC (LSE:ANTO) and Anglo American PLC (LSE:AAL) as preferred global picks due to their leverage to constrained supply and long-term energy transition demand. This counsel comes despite copper futures rising over 15% in the US and 10% on the London Metal Exchange this year, a rally which mining equities have largely underperformed, rendering their valuations more reasonable. However, UBS projects a potential softening in the near-term copper market as speculative flows, tariff-related trade distortions, and physical tightness—key drivers of recent strength—begin to ease, with physical premiums moderating and inventories normalizing. Mine supply remains a critical concern, with Q1 production from major listed miners, including Antofagasta and Anglo American, increasing only 1.2% year-on-year and declining nearly 10% quarter-on-quarter, albeit consistent with seasonal patterns. Production guidance appears increasingly fragile, as evidenced by Teck Resources' forecast cut and potential disruptions at the Kamoa-Kakula complex, leading UBS to forecast global mine production growth below 1% for 2025. Structurally, the investment case for copper is robust, underpinned by demand from electrification, renewables, and electric vehicles. Nevertheless, challenges persist in the refined copper segment, with Chinese smelter output facing feedstock constraints, and global refining margins pressured by low refining charges and tightening scrap supply, leading to operational impacts such as Glencore's closure of its Pasar smelter and Altonorte being temporarily offline. UBS maintains its preference for Antofagasta due to its disciplined strategy and copper focus, and a positive view on Anglo American owing to its copper exposure and restructuring potential, while also favoring Freeport-McMoRan, Zijin Mining, and Sandfire Resources.

Key Decisions for Investors

• Investors should consider a selective approach to copper equities, focusing on companies with disciplined capital allocation and strong asset quality, such as Antofagasta and Anglo American, which are well-positioned for long-term structural demand despite potential near-term market softness.
• Closely monitor developments in copper mine supply, including production guidance from key players and operational disruptions, as these factors are critical given UBS's forecast of sub-1% global mine production growth in 2025 which could impact profitability.
• For those with a medium-term investment horizon, current valuations of copper miners, which have lagged the metal's price surge, may present an opportunity to gain exposure to the energy transition narrative, especially in preferred names with clear strategic advantages.
• Be cognizant of the short-term headwinds in the physical copper market, including moderating premiums and normalizing inventories, which may lead to price volatility before the structural long-term demand drivers fully reassert themselves.
