The head of Rio Tinto has issued a stark warning to the mining industry, saying it will have to work hard to protect margins and generate cash against a backdrop of rising costs and increased political risk.
Rio chief executive Jean Sebastien-Jacques said cost inflation driven by near $80-a-barrel oil was affecting the entire sector and all commodities, while resource nationalism was gaining momentum.
“The outlook for global growth remains positive — but there are some significant risks. Volatility in markets . . . trade wars and resource nationalism are all sources of uncertainty,” Mr Jacques told investors at the Bank of America Merrill Lynch conference in Miami.
