Tariffs and economic growth both globally and at the checkout line.

I'm David Brancaccio in Los Angeles.

The world will see lower economic growth due to tariffs and tariff uncertainty.

This is the conclusion of economists working for the club of rich nations known as the OECD.

The Organization for Economic Cooperation and Development now says economic growth in the U.S.

this year will be a paltry 1.6%.

The OECD blames substantial barriers to trade, diminishing confidence and heightened uncertainty.

It says global economic growth will fall below 3% this year.

The slowdown is expected to be most concentrated in the U.S., Canada, Mexico, and China.

The OECD warns that inflation is also resurfacing with tariffs pushing up prices, adding that

things could get worse if the trade war intensifies,

with higher trade taxes pushing inflation up even more while tamping down growth.

The OECD has some advice for global policymakers collaborate to keep tariffs from ratcheting up

even more and encourage manufacturers to diversify their supply chains. I'm Nancy Marshall

aluminum may not seem that connected to food, but they are critical for packaging.

David Ortega at Michigan State University says think about all those canned goods you buy.

Can tuna, soda, beer, pet food even.
