The ReferenceRate table is a part of the Rate package that stores information about fixed interest rates of various financial instruments. It contains data that is indicative of a specific market reference rate (e.g. U.S. Treasuries, Eurodollar deposits, etc.) on a daily, weekly, or monthly basis, which can be used as a benchmark or reference rate to compare market rates. The information contained within the table can be used to compare the performance of alternative investments over time and understand the relative opportunity costs of holding these assets.
