What causes supply chain disruptions in the global economy?

A supply chain is like a team of friends passing a toy from one to another, if someone drops it or gets stuck, the whole game slows down.

Supply chain disruptions happen when something goes wrong in this teamwork, making it harder for things to move around the world. It's like your friend forgot their backpack and now everyone has to wait while they run home to get it.

Imagine you're waiting for a train ride from New York to California. The train is made of cars, each one carrying different parts of what you need. If the engine breaks down or there's a big snowstorm, the whole train might stop. This is like a supply chain disruption: one part of the world slows things down for everyone else.

Sometimes, lots of people want the same toy at once, maybe it’s a popular video game console. If only one factory makes it and it breaks down, there aren’t enough toys to go around. It's like when your class all wants the same snack during lunchtime, but the vending machine only has one type left. That’s how supply chain disruptions can make things more expensive or harder to find.
