What’s Happening in the Strait of Hormuz? A Super Simple Guide

A Quick Look at the Picture

• Imagine a special jet called an F-35B Lightning II (a plane that can take off straight up like a helicopter).
• On May 13, 2026, this jet flew off a huge U.S. Navy boat named the USS Tripoli (an amphibious assault ship — think of it as a floating airport and troop carrier).
• The jet belonged to a group called Marine Fighter Attack Squadron (VMFA) 121.
• This picture, shared by the U.S. Navy, shows the kind of military muscle involved in the story below.

What Happened on Tuesday?

On Tuesday (the day this news came out), the part of the U.S. military that watches over the Middle East — called U.S. Central Command (CENTCOM) for short — posted on a social media site called X (formerly Twitter). Here is the simple version:

• The U.S. flew planes and hit Iranian targets (places in Iran the U.S. didn’t like).
• This happened just before the U.S. put a blockade back up. A blockade is like building a fence on the water to stop ships from going in or out.
• The fence is around Iranian ports (like water doors to a country) near a narrow, super‑important water road called the Strait of Hormuz.
• The strikes started at 3 p.m. ET (that’s 3 in the afternoon in New York time). They were meant to weaken Iran’s ability to attack regular cargo ships in the strait.
• The water fence (blockade) in the Gulf of Oman (a nearby body of water) was set to start again at 4 p.m. ET.

Important: The Strait of Hormuz is like a tiny hallway that a fifth of the world’s oil walks through. Keeping it safe is a big deal for everyone’s gasoline and the toys made far away.

Why Was There a Break Before?

Let’s walk through the steps that led to this moment:

1. Last month, the U.S. and Iran signed a temporary “stop fighting” deal (ceasefire) as part of a 14‑point memorandum of understanding (a fancy term for a written list of promises).
2. Because of that deal, the U.S. lifted the water fence (blockade) to let ships move more freely.
3. Last week, President Donald Trump said the ceasefire was “over” because both sides argued the other broke the rules, and there were new fights.
4. Monday, Trump said the U.S. would put the blockade back on, because Iran seemed to be trying again to take over the strait by force.
5. Even during the ceasefire, fewer merchant ships (boats carrying toys, food, etc.) used the strait than before the war. After the fighting restarted, even fewer came.

Before the war (which the U.S. and Israel started against Iran in late February), 20% of the world’s oil traveled through this water hallway.

Trump’s Toll Idea (and the Quick Change)

When Trump announced the blockade was back, he also posted on his own social media site, Truth Social (a website where he shares messages). He said two things:

• “The Hormuz Strait is OPEN, and will remain OPEN, with or without Iran.”
• The U.S. would ask for a 20% reimbursement on all cargo (stuff on ships) going through the strait. Think of it like a teacher saying, “You must pay me 20 cents on every dollar of snacks you carry through the hall.”

But this idea did not go well:

• Energy experts (people who study fuel) were very doubtful.
• Shipping groups (including the United Nations’ International Maritime Organization — the UN team that makes sea rules) said “no way.”
• They even remembered videos of Trump’s own officials saying it would be illegal (against the rules) for any country to charge money in international water.

So, one day later, Trump changed his mind:

• On Tuesday morning, he posted he would replace the toll with “Trade and Investment Deals” — meaning the wealthy countries nearby (Gulf States) would promise to buy more from or build in the U.S. instead.
• Later at the White House, he said world leaders called him and told him “we’d love to do it a different way.” He agreed, saying he doesn’t think anyone should charge a fee for the strait, but the U.S. was just asking for repayment.
• He talked with Saudi Arabia, the United Arab Emirates, Qatar, Bahrain, Kuwait, and others. As of this news, none of them have said they will invest more in the U.S. this week.

Breaking News: This is breaking news — meaning it’s still developing. The story might change, so keep an eye out for updates.

Summary

To wrap it up in a nutshell:

• The U.S. hit Iranian targets and restarted a sea blockade near the Strait of Hormuz on Tuesday.
• This happened after a short ceasefire failed.
• The strait is a vital oil path; before the war, 20% of world oil used it.
• Trump first wanted a 20% fee on ships, but after pushback, he swapped that for promised trade deals with neighboring countries (which haven’t been announced yet).
• The situation is ongoing and could change.

FAQ

Q1: What is the Strait of Hormuz, in kid terms?
A: It’s a narrow strip of water between Iran and other countries, like a slender hallway connecting a big ocean to a big gulf. Lots of ships carrying oil use it, so if it’s blocked, the whole world feels it.

Q2: Why did the U.S. attack Iran?
A: The U.S. military said it hit Iranian places to make it harder for Iran to attack regular merchant ships in that important water hallway. They said it was to protect the flow of goods.

Q3: What is a blockade?
A: It’s when a country uses ships or planes to block another country’s ports, like putting a “do not enter” fence on the water so their ships can’t get out and others can’t go in.

Q4: Why did Trump decide not to charge the 20% fee?
A: Many experts and other countries said it was illegal and unfair. Trump got phone calls from world leaders asking for another way, and he agreed that nobody should charge a fee for the strait, so he switched to asking for trade deals instead.

Q5: Is the strait actually closed?
A: Trump says it is open and will stay open. But the number of ships going through has dropped a lot because of the fighting and fear, even though the water itself isn’t physically shut.
