When financial markets in the United States crash, so does the U.S. economy. Just remember what happened back in 2008. The financial markets crashed, the credit markets froze up, and suddenly the economy went into cardiac arrest. Well, there are very few things that could cause the financial markets to crash harder or farther than a derivatives panic. Sadly, most Americans don't even understand what derivatives are. Unlike stocks and bonds, a derivative is not an investment in anything real. Rather, a derivative is a legal bet on the future value or performance of something else. Just like you can go to Las Vegas and bet on who will win the football games this weekend, bankers on Wall Street make trillions of dollars of bets about how interest rates will perform in the future and about what credit instruments are likely to default. Wall Street has been transformed into a gigantic casino where people are betting on just about anything that you can imagine.
