How do central banks use interest rates to control the economy?

Central banks use interest rates to help keep the economy running smoothly, like a traffic light helps cars move safely through an intersection.

Imagine you're saving money in a piggy bank. If the central bank raises interest rates, it's like your piggy bank starts giving you more candy every day for keeping your coins safe. That makes people want to save more money. But if they lower interest rates, it’s like the piggy bank gives out fewer candies, so people might prefer to spend their money now instead of saving it.

Think of a bakery. If interest rates are low, it's easier for the baker to borrow money to buy more flour and sugar. That means they can make more bread and cakes, which gives them more customers and more money. The whole town starts feeling happy because there’s more food and more jobs.

But if interest rates go up, borrowing becomes harder. The baker might have to slow down production, and the town might feel a bit slower too, like when you take off your shoes before bed, everything feels calm and quiet.

So, central banks use interest rates as their tool to help the economy speed up or slow down just right!
