Economic Terrorism is when someone uses financial means to cause disruption and harm to a country's economic stability. For example, terrorists might use their money to buy hard-to-get items that can be used to build bombs or buy guns, or they might make investments that cause prices to go up or down, affecting people's ability to buy or sell what they need. This can cause a lot of economic damage, and make it harder for people to live their lives normally because they can't buy the things they need.
