Hey kiddo, sometimes when the grown-ups say there's a "global recession," it means that there's a big problem with money all around the world. In a lot of different countries, people are having trouble buying things or finding jobs.
See, sometimes the grown-ups like to buy things or invest their money in different companies, and that helps those companies grow and make more money. But if lots of people aren't buying things or investing, then those companies might not make as much money. And when lots of companies aren't making as much money, it can affect the whole world's economy, kind of like dominoes falling down.
When that happens, it can be a really tough time for a lot of people, because they might not have as much money as they used to, or they might not be able to find a job. But don't worry too much, because the grown-ups are working hard to try to fix things and make it better for everyone.
