Purpose

LIBOR serves two primary purposes in modern markets as:

  • Reference rate: A reference rate is a rate that financial instruments can contract upon to establish the terms of agreement.
  • Benchmark rate: A benchmark rate reflects a relative performance measure, oftentimes for investment returns or funding costs.

LIBOR serves as the primary reference rate for short-term floating rate financial contracts like swaps and futures

Who calculates LIBOR?

The British Bankers’ Association (BBA), a private trade association, constructs LIBOR, and Thomson Reuters publishes it worldwide.
