5 Best-performing Copper Stocks on the TSX in 2025
Copper prices have seen considerable gains in 2025, reaching a record high on the COMEX of US$5.68 per pound on July 8. Rising prices and supportive policy have elevated many copper stocks.
The price of copper has experienced volatility since the start of the year, as shifting US trade policy has created competing scenarios amid recession and the imposition of tariffs.
On July 8, the price spiked to fresh all-time highs after US President Donald Trump announced he would impose a 50 percent tariff on all copper being imported into the United States.
Although no specific timeline was set for when the tariffs would take effect, the price of metals gained on the COMEX as traders worked to secure supplies ahead of any potential deadline. Despite since recording a marginal pullback, copper has continued to trade near record highs.
Meanwhile, the copper price on the London Metals Exchange didn’t receive the same lift from the tariff news, although it did briefly move above US$10,000 per metric ton on July 2 before pulling back to under US$9,700.
