Historical Context
The term “basis point” has been widely used in the financial industry for decades. Its origins lie in the need for a unit of measure that could describe very small changes in percentages with precision. This level of precision is crucial in markets where even minute variations can have significant financial implications.
Definition
A basis point (bps) is one hundredth of one percent (0.01%). It is a common unit of measure for interest rates and other percentages in finance, representing 0.0001 or 0.01%.
Key Events
- 1971: Introduction of floating exchange rates increases the need for precision in financial communication.
- 1980s: The widespread adoption of computers in trading further underscores the necessity of accurate and minute measurement units like basis points.
- 2007-2008: The Financial Crisis highlights the importance of basis points in understanding small percentage changes in interest rates and yields.
Explanation and Importance
In financial calculations, dealing with percentages is routine, and often these percentages are in decimal forms that need precision. Basis points are essential because they provide this precision:
- Example: An interest rate increase from 2.00% to 2.50% can be expressed as a 50 basis point increase.
Mathematical Representation
If an interest rate changes from \( x % \) to \( y % \), the change in basis points (bps) can be calculated as:
Types and Categories
- Interest Rates: Used for changes in rates on bonds, loans, etc.
- Yields: Variations in yields on securities like bonds.
- Credit Spreads: Differences in yields between different types of debt securities.
- Stock Prices: Minor changes in stock prices and dividends are also sometimes described in basis points.
