Trump Heralds Unease in Global Halls of Power With Tariff Threat

(Bloomberg) -- All it took was a single social media post by Donald Trump for world leaders to plunge into response mode, US automaker stocks to tumble and investors to begin scrambling to assess potential economic impact.

And while the US president-elect’s threat on Truth Social to impose 25% tariffs on all goods from Mexico and Canada and 10% on products from China may ultimately prove to be a negotiating tactic, it sent a clear signal: While Trump hasn’t yet assumed the White House, the second Trump era has effectively begun.

President Claudia Sheinbaum of Mexico suggested her country could respond to the threatened tariffs with levies of its own, warning the economic consequences would be dire.

“One tariff will be followed by another in response, and so on until we put common companies at risk,” Sheinbaum said at her daily press conference.

For Canadian officials, the online post landed just as a special cabinet group meeting on US relations was wrapping up. Prime Minister Justin Trudeau was soon on the phone with Trump, working to assure the president-elect he’d heard the message — but also pointing out that the issues at the Canadian border are tiny compared to the US-Mexico border.

Still, Canada is not ruling out striking back. Finance Minister Chrystia Freeland, speaking to reporters Tuesday afternoon, pointed out that her government responded dollar-for-dollar when Trump imposed tariffs on Canadian steel and aluminum during his first term.

“The important thing is we got through it, and our response was successful,” Freeland said. “The reason we were able to do that is we were smart, we were united, we were strong.”

‘Most Beautiful Word’

Trump’s declaration follows a campaign in which he proclaimed that tariff is “the most beautiful word in the dictionary” and pledged repeatedly to enact sweeping new levies as a cornerstone of his economic agenda.

His announcement, then, didn’t land as a total shock in Mexico City or Ottawa. But it underscored a delicate task ahead for key US trading partners as they aim for economic stability and seek to keep ties with Washington from becoming frosty. Trump centered his threat on the countries curbing the flow of fentanyl and migrants into the US.
