The global fiasco that Donald Trump has created around the Strait of Hormuz is rapidly getting worse.

An international agency says the closing of the strait is creating the largest global oil supply disruption in history.

And a striking New York Times report outlines the enormous consequences this is starting to have for the world economy.

There's still no sign that Trump knows how to get out of this mess.

CNN reports that there's rising alarm and urgency within the administration over it,

and Trump just unleashed a bizarre tweet about the situation that underscores just how lost he truly is.

demonstrating to Trump the limits of sheer bullying, which Trump thinks can accomplish anything.

The International Energy Agency just announced that this is causing, quote, the largest supply disruption in the history of the global oil market.

Nick, can you boil down what that really means?

It means widespread economic disruption. There is reliance on energy through all aspects of the

economy. There's also additional oil effects that things like used for metallurgy processes,

for example, different byproducts used for agriculture.

And oil is a global commodity, meaning that it is produce in many different places, the United States both imports and exports.

It refines products. It drills oil, crude oil. And all of this is on a day of supply chain.

So when things get disrupted, there's a little slack in the system, but really not much.

And then the prices go up.
