People who trusted in their accumulated wealth and lost property or loved ones in the Rapture will not be able to recover insurance benefits. Within days after the Rapture financial advisors will realize that collapse of the insurance industry is imminent and unavoidable. Take the hit now, while the stock is still worth something. This will trigger panic selling by large shareholders such as mutual funds, retirement funds, etc. Most banks, major corporations, and insurance companies have strong ties to each other.
Major corporations have lines of credit with banks.
Many insurance companies own large blocks of stock in banks and vice-versa. Within hours after the bulletins there will be a drop of several hundred points in major stock markets. For a number of years, major stock brokerages have constantly monitored the world's financial markets by computer. The governments of the major financial powers will have no choice but to suspend trading in all the major stock exchanges. Of course, this will greatly increase the panic among the general population.
