Globally gold prices rose more than 1% on Friday as investors sought safe-haven assets following U.S. President Donald Trump's announcement of new tariffs, while silver reached its highest level in over 13 years, Reuters reported.
Spot gold gained 1% to $3,356.93 per ounce after touching its highest level since June 24 earlier in the session. U.S. gold futures closed up 1.4% at $3,371.20.
Global stocks fell after Trump ramped up his tariff assault on Canada, saying the U.S. would impose a 35% tariff on imports next month and planned to impose blanket tariffs of 15% or 20% on most other trading partners.
"We are in an environment where the uncertainty premium is back in the market and gold is getting a safe-haven bid," said Aakash Doshi, global head of gold strategy at State Street Global Advisors.
"I think the range in the third quarter is most likely between $3,100 and $3,500. It's been a very strong first half of the year, and I believe we're now in a bit more of a consolidation phase," Doshi added, as cited by Reuters.
