Alright kiddo, so let's say your friend Tommy owes you some money for the candy you shared with him. But Tommy doesn't have the money right now to pay you back. So you decide to give him a toy instead of the money, hoping that he can use it to make some money and pay you back later.
This is kind of what happens with the government when they need to borrow money. They issue something called "government bonds" to people and institutional investors (like banks) who are willing to lend them money. These bonds promise to pay back the money with interest at a future date.
Now, let's say that the government has borrowed a lot of money and they need to find a way to pay it back. This is where debt monetization comes in. Essentially, the government can "print" more money (or create digital money) out of thin air and use it to buy up some of the bonds they've issued. This means that they are using newly created money to pay off their debts.
This might sound like a good solution, but it can have some drawbacks. The more money the government creates, the less valuable each individual dollar becomes. This can lead to something called inflation, where prices for goods and services go up because each dollar is worth less than before. It's kind of like if you had too many toys and they all became less valuable because there were too many of them around.
So while debt monetization can be a way for the government to pay off their debts, they need to be careful not to create too much money and cause inflation. Just like you need to be careful not to give away too many toys or they'll lose their value!
