More: With over 3,000 stores worldwide and an annual revenue exceeding $6 billion, Levi's is one of the largest American brands to warn of the indirect effect on its operations from global opposition to Trump's trade policies.

An already observed side effect of Trump's tariffs has been a surge in calls to boycott American companies abroad. This first emerged in Canada, where ongoing grassroots and lawmaker-led boycotts have made a notable dent in some American companies' bottom lines. The recent decision to impose a 50 percent tariff on Indian goods has also sparked a similar "buy Indian" movement in the country.

One expert told Newsweek that we can expect boycotts of U.S. brands to continue through 2025, especially for companies such as Levi's that have "leveraged their American identity" and whose products are relatively easy to substitute.
