The Institute of International Finance is a big group of people who work together to make sure that different countries around the world are playing fair with money. Imagine that you and your friends are playing a game, but some of your friends keep changing the rules to make it easier for them to win. That's not fair and it's not fun for everyone else. The Institute of International Finance helps make sure that countries are not changing the rules of the game when it comes to money and finance so that everyone can play fair and everyone can win. This group of people talks to each other, shares information, and helps make decisions that are fair for everyone.
