This document discusses interest rate swaps. It defines an interest rate swap as an agreement to exchange interest rate payments, with one leg fixed and the other floating. Common types include paying fixed rate interest to receive floating, and vice versa. Interest rate swaps are used to hedge against rising or falling interest rates by transforming fixed deposits/borrowings to floating, or floating to fixed. Examples show how swaps can benefit entities by reducing income/funding costs if rates move in the desired direction.
