“On the campaign trail, Trump pledged to put a tariff of between 10 percent and 20 percent on all imports to the United States, along with a 60 percent tariff on Chinese goods and a 25 percent import surcharge on Canadian and Mexican wares — at least, until our neighbors choke off the flow of all migrants and drugs across America’s northern and southern borders.
This protectionist agenda is far more radical than anything Trump attempted during his first term. It threatens to hamper American tech companies by increasing the cost of semiconductors, depress stock valuations by reducing economic growth and fueling a global trade war, and disrupt the US auto industry, whose supply chains were built around the presumption of duty-free trade with Mexico.
Thus, American investors, executives, and entrepreneurs watched Trump’s first day in office with bated breath: Would his inaugural address and initial executive orders prioritize corporate America’s financial interest in relatively free global exchange — or his own ideological fixation on trade deficits?
Trump’s Day 1 actions did not fully clarify his priorities on this front. In his inaugural speech, the president reiterated his broad commitment to protectionism. Meanwhile, his administration prepared to launch federal investigations into America’s trade deficit in general, as well as the trade practices of China, Mexico, and Canada in particular.
Nevertheless, Trump did not actually establish any new tariffs on his first day in office, as his administration’s arch-protectionists had hoped that he would.
Investors interpreted Trump’s caution as a sign that he would be heeding his advisers’ push for a more limited and incremental tariff policy; stocks rose Monday while the US dollar fell (stiff tariffs would increase the value of America’s currency).
Wall Street’s relief may be premature. Trump appears as ideologically perturbed by America’s trade deficit as ever.”

“Imposing even a 10 percent tariff on all imported goods would not only harm various business interests, but would also likely increase costs for consumers. Thus, such a duty would harm both Trump’s donors and voters.
If Trump’s first term is any guide, his universal tariff would not even redound to the benefit of American manufacturers, who would be vulnerable to higher costs and retaliatory tariffs from foreign nations. Generally speaking, presidents seek to avoid enacting policies that harm the bulk of their coalition, to the benefit of a narrow band of ideologues. And this is what implementing Trump’s grandest visions for trade policy would likely entail.
Second, the imposition of a universal tariff would roil stock markets. During Trump’s first term in office, he monitored the markets’ performance obsessively, tweeting about it incessantly and suggesting that stock values were a barometer of sound policy, warning in 2018, “If Democrats take over Congress, the stock market will plummet.”
Finally, Trump has recently shown some sensitivity to the interests of his newfound friends in tech, even when those interests conflict with the tenets of rightwing nationalism. Over the holidays, Elon Musk feuded with their co-partisans over the desirability of high-skill immigration and the H-1B visa, which help American tech companies to hire foreign talent. Trump ultimately expressed support for Musk’s position.”
