CNBC host Jim Cramer’s excitement about President Donald Trump’s latest trade deal got the better of him on Monday.

When President Donald Trump revealed that his administration had struck a "massive" trade and investment deal with Japan, he described it as "completed"—but it must still pass the Japanese parliament, called the Diet, which is riven with political turmoil.

The recent trade agreement between President Donald Trump and Japan, reducing import tariffs on Japanese vehicles from 25% to 15%, offers a mixed blessing for Japanese automakers. While it provides some relief,

Outside economists say that high tariffs are still likely to raise prices for American consumers, dampen the Federal Reserve’s ability to lower interest rates and make the U.S. economy less efficient over time. Democrats say the middle class and poor will ultimately pay for the tariffs.

The Japanese government, not companies, is poised to back U.S. infrastructure projects of the president’s choosing.

Sohei Kamiya's Sanseitō Party won 14 seats in Japan's Upper House elections, appealing to young voters with a "Japanese first" platform focused on culture, birth rates and food security.

The 15% tariff would be lower than previously threatened, but it would remain a high duty on America’s largest trading partner.
