One of these days we will get through this show without using the word uncertainty.

Today, however, is not that day.

From American Public Media, this is Marketplace.

Thank you. In Los Angeles, I'm Kyle Riznell.

It is Tuesday, today the 21st of April.

Good as always to have you along, everybody.

The on again, off again, on off, on, again, nature of President Trump's war against Iran seems to be in an off

There are some caveats and conditions, but the net effect does seem to be no more bombing

The market response tomorrow, TBD, if traders aren't numbed the whole thing already.

into the safest assets out there, among them, of course, the U.S. dollar, the value of which

jumped when the war started and over the first month of it or so rose about 3%. Since, though,

the greenback has given up nearly all of those gains.

Marketplace's Justin Ho has more on what's weighing on the dollar and what it might mean.

The dollar's value rose early in the war, in large part because the conflict has had an outsized impact on the rest of the world.

That's bad for the United States.
