11. 9/11, $40 Billion

This incident was indeed one of the darkest days in America’s history and for the rest of the world too. More than 2000 people were killed, and the business interruption amount rose to be $11 billion. Victims of this attack also received claims. Insurance companies had to pay $40 billion, due to which the insurance companies later changed their policies and decided not to cover any cases of terrorism.
