[00:00:00]Here is the Strait of Hormuz. This very narrow waterway, it's about 20 miles wide, that is in the territorial waters of Iran and the Sultanate of Oman. Iran has about 12% of the world's proven oil reserves. That's a lot of oil, and through the Strait of Hormuz passes about 20% of the world's oil. If you want to get oil out of what's called the Persian or Arabian Gulf, it mainly has to go through the Strait of Hormuz. Now, Saudi Arabia has a pipeline that lets it send some of its oil across to the Red Sea.

[00:00:36]The Emiratis have a pipeline that also allows them to bypass some of the Strait of Hormuz, but it's not enough. And when there is risk here, when it looks like there's going to be a supply disruption, that gets priced into energy markets, and you and I pay higher prices at the pump. Now, in addition to the Strait of Hormuz, there are two other places that you might have heard people talk about.

[00:00:59]One is Kharg Island, which is right there. And that's a major Iranian facility for loading tankers and for storing oil. And there is now a proposal on the table for the United States to actually seize Kharg Island, and that would deal a really crippling blow to the Iranians. The second is actually on the other side of the Arabian Peninsula, and that's right here. That's called the Bab el-Mandeb Strait, and that separates Yemen from Africa on the Red Sea.

[00:01:30]Practically everything that goes through the Suez Canal has to ultimately go through Bab el-Mandeb. We're talking there about 10 to 15% of world trade.

[00:01:39]And guess who operates right here in Bab el-Mandeb? An organization called Ansar Allah, known popularly as the Houthis.

[00:01:47]They are an Iranian client, and they have the capacity to really disrupt and interdict shipping through the Bab el-Mandeb Strait. And so, between the Strait of Hormuz and Bab el Mandeb, the Iranians have the ability to put a major hurt on the global economy.
