Bluffs and Bluster Aside, Trump’s Tariffs Are Here to Stay

President Trump’s on-again, off-again tariffs have prompted investors to bet that he will “always chicken out” and given businesses and foreign leaders hope that the leader of the world’s largest economy will ultimately back down from his threats if they prove too economically disruptive.

Events of the past week have cast serious doubt on that bet. As Mr. Trump renews trade threats against more than two dozen trading partners, he is once again proving his fondness for tariffs, and embracing import taxes in a way that no other president has since the Great Depression.

A self-described “tariff man,” Mr. Trump has continually extolled the virtues of heavily taxing imports as a way to raise revenue and cajole factories to relocate to the United States. While the president may ultimately give way on some of his most recent threats, he has still steadily and dramatically raised tariffs to levels not seen in a century.

Over the past week, Mr. Trump has threatened 25 trading partners with punishing levies on Aug. 1 unless they sign trade deals that Mr. Trump finds acceptable. The list of countries he plans to raise tariffs on include some of America’s biggest sources of imports, including the European Union, Japan, Mexico, Brazil, South Korea and Thailand. Those countries had been in active talks with the United States about resolving Mr. Trump’s concerns in an effort to avoid tariffs.

Several may still reach deals to avert some of the levies, including India, the European Union, Taiwan and Japan.

But even if some deals are reached, American tariffs on trading partners are still likely to rise significantly. That was the case with the two trade agreement frameworks that the Trump administration has so far announced, with Britain and Vietnam, both of which leave double-digit tariffs in place.
