Copper Climbs as Supreme Court Strikes Down Trump’s Tariffs

Copper climbed in London, tracking gains in US stock markets after the US Supreme Court struck down President Donald Trump’s sweeping reciprocal tariffs, which have weighed heavily on the outlook for global trade.

Prices rose as much as 1.3% on the London Metal Exchange before paring gains after the court said the administration had exceeded its authority when it imposed the tariffs on trading partners. Those levies are separate to the sector-specific tariffs Trump put in place on aluminum, steel and copper products on national security grounds.
