Bank of America on Friday revised its recommendations for two of the largest diversified miners, downgrading Rio Tinto and BHP Group from Buy to Neutral. The analysts framed the move as a top-down decision driven by macro and valuation considerations rather than company-specific developments.
Analysts led by Jason Fairclough said that although they left their price targets unchanged - A$69 per share for BHP and 9,300 pence for Rio Tinto - the combination of stretched valuations and rising external risks reduces the upside potential relative to downside exposure. Both stocks, they noted, currently sit near the upper bound of the historical price-to-net-present-value range typically seen across large-cap diversified miners in different parts of the cycle.
The team also pointed to the evolution of the sector's earnings narrative. What began as an earnings upgrade cycle for mining companies in mid-2025 has progressed to a point where the "easy" gains are largely behind investors, the analysts said. While revisions to earnings estimates continue to be positive, the group cautioned that typical upgrade cycles tend to run for two to three years, implying the current phase may be approaching its later stages. They also signaled that cost pressures could become more prominent from here.
China looms large in the analysts' assessment. The country accounts for roughly half of demand for most metals and mined products, and closer to 70% of the seaborne iron ore market. China’s credit impulse - a gauge of new credit as a share of GDP - has turned negative on a year-on-year basis. Historical correlations cited by the team suggest mining equity performance tends to follow this indicator with a six- to eight-month lag, a dynamic that raises concern for miners exposed to commodity demand from China.
Iron ore prices were described as somewhat high relative to both historical averages and seasonal norms, reinforcing the view that some of the cyclical upside has already been realized. On the oil and base metals side, BofA flagged the possibility of demand shocks related to the escalating Middle East conflict. The analysts highlighted four past episodes over the last 25 years - the dot-com bust, the global financial crisis, the 2015 China hard-landing scare, and the Covid shock - when similar disruptions contributed to copper prices falling toward marginal cost levels.
Although such a severe outcome is not presented as the base case, the analysts warned that the probability of unexpected negative events - the "risk tails" - has increased. That heightened tail risk, coupled with current valuation levels and a weakening credit impulse in China, underpins the bank's decision to adopt a more neutral view on both Rio Tinto and BHP.
Price targets retained: BHP - A$69; Rio Tinto - 9,300 pence.
Analysts' characterization: A top-down downgrade driven by valuation, China credit impulse deterioration, and expanding macro risk, rather than company-specific factors.
