Copper close to testing $10 000 as BHP bid points to supply risk

Copper made a fresh push toward five digits as BHP Group’s blockbuster offer to buy Anglo American lent support to bulls who say the metal is headed for long-term shortages and high prices. The world’s biggest miner has proposed a $39-billion takeover of Anglo, chiefly targeting its smaller rival’s South American copper mines. The size and timing of the bid — with copper up 16% this year — is a stark sign of how resources giants are trying to muscle in on a commodity that’s crucial to green industries.
