LIBOR Index and Rates. LIBOR is an abbreviation for the London Interbank Offered Rate and is the interest rate offered by a specific group of London banks for U.S. dollar deposits of a stated maturity. Interest only loans come in a wide variety of forms including both long and short term interest rates.
As mentioned by Doug Mewhirter, LIBOR is an average of the rate banks declare lending (or being ready to lend) to each other. That is not necessarily the actual rate at which they lend to each other. There is an overnight LIBOR, 1-month LIBOR, 3-month LIBOR, etc. depending on the term of the loan.
