The international lender of last resort helps countries when they are facing a crisis. It's like when your parents lend you money when you need help. The international lender of last resort is a place where countries go when they need financial help to pay for things like healthcare, schools, roads and other important services that people need. When a country is facing financial trouble, the lender will loan money to them so they can pay for these important services that people need. This is a special kind of lending because it's done on a global level and the money comes from all around the world. Countries can repay the money later when times are better, but for now the lender is helping them out when they really need it.
