The tension between Iran and the United States has reached a breaking point over the Strait of Hormuz.
As a primary route for global energy, any blockage here could cause a "brutal wave" of financial instability across the globe, including a massive jump in petrol prices.
The Strait of Hormuz is a narrow passage that connects oil-rich Gulf countries to the rest of the world. It is the most vital "choke point" for global energy.
Iran has warned that any ship carrying oil for "hostile allies" will be considered a target for their military.
Oil prices have been jumping wildly, hitting their highest levels since 2022. Traders are terrified that a total blockade will lead to a global energy shortage.
Because the sea isn't safe, many shipping operators are taking longer, more expensive routes, which adds to the rising cost of international trade.
