How Does Fractional Reserve Banking and the Money Multiplier Made Simple Work?

Imagine you're playing with building blocks, every time someone adds a new block, more blocks can be made from it! That's how fractional reserve banking and the money multiplier work.

When a bank gets money, like when you deposit your allowance in a piggy bank, it doesn’t keep all of that money. Instead, it keeps some, just like you might keep a few coins for emergencies, and lends out the rest to someone else, like giving a friend a loan to buy ice cream.

Think of banks as clever chefs who can make more cookies from one batch. If a bank keeps 10% of your deposit (like saving 10 blocks), it can lend out the other 90%. When that money is used again, maybe for buying toys or snacks, it goes to another bank, and the process repeats.

This repeating cycle is called the money multiplier. It's like a chain reaction: one deposit leads to more loans, which lead to more deposits, and so on, just like how a single seed can grow into a big tree!

So banks don’t need all your money to make things happen, they only need a piece of it, and from that little piece, they can create much more!
