Swaps

  • Swap: A contract in which two counterparties agree to exchange specified amounts of assets (e.g., cash, financial assets or commodities) at a set of given future dates.

Example: LIBOR swap
  • Interest rate swap: a fixed rate of interest is exchanged for a reference floating rate.
  • For example, the London Interbank Offered Rate (LIBOR) could be used

  • as the reference floating rate.
  • Payments are made periodically, e.g., at the end of each 6-month sub-

  • period.
  • Example: assume the current 1-month LIBOR is 0.5%. You enter into a 5- year fixed-for-floating swap with the fixed rate of 0.7%.
  • If LIBOR rises in the future, you receive higher payments on the floating

  • leg, continue making fixed payments on the fixed leg.
  • The swap represents a bet on higher future values of LIBOR.
