The LIBOR is the world's most widely used benchmark for short-term interest rates. It's important because it is the rate at which the world's most preferred borrowers are able to borrow money. It is also the rate upon which rates for less preferred borrowers are based. For example, a multinational corporation with a very good credit rating may be able to borrow money for one year at LIBOR plus four or five points.
Countries that rely on the LIBOR for a reference rate include the United States, Canada, Switzerland and the U.K.
