Trump's latest tariff salvo fuels economic uncertainty, experts say

A flurry of tariff threats by President Trump leaves U.S. consumers and businesses in limbo ahead of an Aug. 1 deadline to deploy the import duties against more than 50 countries around the world, according to economists and trade experts.

"Nobody knows whether these are threats or whether they will become policy, so it seems like everyone has become desensitized to them," EY Parthenon chief economist Gregory Daco told CBS MoneyWatch, adding that uncertainty over U.S. tariffs leaves companies in "a very dense fog."

Mr. Trump on Saturday announced he is imposing 30% tariffs against Mexico and the 27-member European Union. That followed moves to threaten tariffs ranging from 20% to 50% on roughly two dozen countries, including key U.S. trading partners such as Brazil, Canada, Japan and South Korea.
