A US markets analyst suspects Donald Trump is trying to buy time by lowering tariffs on most countries to a blanket 10 percent for 90 days.

But the US President's hiked them for China - to 125 percent.

Scott Shellady says 75 countries are reportedly seeking an audience with the President. 

"The 90 day pause is so he can get through the backlog of countries that said they want to do a deal."
