Retail giants are facing sharp declines in after-hours trading as new tariffs from the US on imports from China, the European Union, and Vietnam begin to rattle markets. Walmart and Amazon both saw their shares fall, with Nike also heavily impacted due to its dependence on Chinese manufacturing.

Walmart's drop of over 4% reflects its heavy reliance on Chinese imports, with roughly 70% of its merchandise tied to the country. Amazon, similarly exposed through its third-party sellers, dipped close to 5% amid fears that rising costs will force sellers to raise prices, dampening consumer demand. These developments could severely affect the upcoming holiday shopping season.

Nike, meanwhile, saw shares fall by more than 6% as news emerged that many of its products, including popular sneakers, are produced in China and Vietnam. Although the company has been diversifying production to Vietnam, the move offers little relief now, as Vietnam faces an even steeper 46% tariff. The new policies may force widespread price hikes, putting further pressure on consumers and the broader retail sector.
