How do central banks use interest rates to fight inflation?

Central banks use interest rates to control how much money is flowing around in the economy, like a parent controlling how many cookies kids can eat.

Imagine you're at a candy store. If the interest rate is low, it's like getting a discount, people borrow more money and spend it on things like toys, ice cream, or video games. But when there are too many treats in the economy, prices go up, and that’s called inflation.

Now, if the central bank wants to slow down inflation, they raise the interest rate. This is like telling kids, "You can only eat one cookie now, save the rest for later!" When borrowing becomes more expensive, people spend less money, so prices don’t go up as fast.

Think of a central bank like a traffic light at a busy intersection. When there's too much traffic (too much spending), the light turns red, slowing things down. That’s like raising interest rates. People and businesses hit the brakes, spending less, which helps bring prices back to normal.

When inflation is under control, the central bank might lower the interest rate again, letting more money flow around, just like giving kids another cookie!
