How Did the Dollar Become the World's Main Currency?

The dollar became the world’s main currency because many people agreed to use it for trading, just like kids agree on a game rule.

Long ago, countries used their own money, like how some kids have coins and others have stickers. But when the United States got really strong after World War II, other countries started using dollar bills instead of their own money. It was easier because the dollar was stable, like a good friend who always shows up on time.

Countries also used something called the Bretton Woods system, which is like a big agreement where everyone says, “We’ll use dollars to trade with each other.” This made it so countries could buy things from each other without having to change their money every time, just like how you don’t need to swap your toys every time you play.

Over time, more and more people used the dollar for banking, travel, and even shopping. It became the most popular currency in the world, like the favorite snack at a party!
