- Copper rose toward $14,700 a ton as workers at the world's biggest copper mine threatened imminent strike action.
- Unions representing about a quarter of direct employees at BHP Group's Escondida mine in Chile said a strike would begin from 8:00 a.m. local time on Wednesday after wage talks failed to produce an agreement.
- A Federal Reserve official played down the need for more than one additional rate hike this year, a secondary factor in the day's copper move.
- Any stoppage at Escondida would add to a bumpy year for copper supply from Chile.
