Okay kiddo, so let's imagine that you and your friend like to play a game called "trading toys." You both have lots of toys, but some of them your friend likes more than their own toys, and vice versa. So you decide to trade some toys with each other to make each other happy. That's kind of like what international finance is all about.
But instead of toys, countries trade lots of different things like money, goods, and services. For example, America might sell iPhones to China, and China might sell us clothes. This makes both countries happy because America gets money from selling iPhones, and China gets money from selling clothes.
But sometimes, countries don't always have enough money to pay for all the things they want to buy. So they might borrow money from other countries, kind of like borrowing money from your parents or grandparents. This is called a "foreign loan." But just like with your allowance, if you borrow too much money, you might not be able to pay it back. The same thing can happen with countries, and that's called "debt."
International finance also involves things like exchange rates, which are like the prices of different currencies. One day, the value of the dollar might be higher compared to other currencies, and the next day it might be lower. This affects how much things cost to buy and sell, and can impact countries' economies.
So, international finance really just means how countries trade with each other, borrow money from each other, and exchange money between each other. It's kind of like playing "trading toys," but on a much bigger scale!
