It serves as the foundation for the interest rates that banks charge their customers for loans and offer for deposits. This article will explore the historical context, significance, types, key events, mathematical models, and broader implications of the base rate.

Types

• Central Bank Base Rate: The rate at which central banks lend to commercial banks.
• Commercial Base Rate: The rate set by commercial banks for their customers, often adjusted above the central bank’s base rate.

Mathematical Models

The relationship between the base rate (BR) and other interest rates can be expressed using the formula:
