Why are interest rates currently so high in many countries?

Interest rates are currently high because money is in short supply, just like toys on a special day at school.

Imagine you and your friends all want to borrow a toy from the teacher for recess, but there’s only one toy left. The teacher says, “You can have it, but you’ll have to pay me back with extra candies.” That’s like interest, an extra amount you give for borrowing something.

In real life, banks are like the teacher. When there aren’t enough toys (or money), banks say, “We’ll lend you money, but you have to pay us back with a little more.” That’s how interest rates go up, it's like the teacher asking for extra candies because there aren’t enough toys to share.

Also, sometimes grown-ups save a lot of money instead of spending it. It's like when you put all your candies in a jar and don’t eat them, banks have more money saved up, so they can lend it out without needing as many extra candies (or interest). But if people are saving more, that means there’s less money around for others to borrow, making interest rates go higher.
