Why are global supply chains still facing so many disruptions?

Global supply chains are like giant toy trains that carry our favorite snacks and clothes from one place to another, but sometimes they get stuck on the tracks.

Imagine you're playing with a train set, and every car has a special job: some bring blocks, others bring crayons. Now picture this train going from your house to your friend's house across town. If one of the cars gets stuck at a red light or breaks down, the whole train slows down, and sometimes it even stops completely.

Supply chains are like that toy train but much bigger. They go all around the world, bringing things like toys, phones, and food from factories in faraway places to your local store. But when something goes wrong, like a big storm hits a port or a truck can't drive because of a traffic jam, it’s like a car on the toy train getting stuck. That causes delays, and everything takes longer to arrive.

Also, sometimes too many people want the same thing at once. It's like if all your friends came over for a party and wanted the same snack, there wouldn’t be enough to go around! That makes things even harder for the big toy train to move smoothly.
