LIBOR is the London Interbank Offered Rate. LIBOR is the rate charged by one bank to another for lending money. The LIBOR is an international index that follows world economic conditions. LIBOR-indexed ARMs (Adjustable Rate Mortgages) offer borrowers aggressive initial rates and have proven to be competitive with popular ARM indexes like the Treasury bill.

With the LIBOR ARMs borrowers are generally protected from wide fluctuations in interest rates by periodic and lifetime interest rate caps.
