Converting Yearly 3-Month T-Bill Rates to Daily Rates
Direct conversion of yearly 3-Month Treasury Bill rates to daily rates is not straightforward. Here's a breakdown:
* Yearly Rates Represent Annualized Returns: 3-Month T-Bill rates are typically quoted as annualized yields, reflecting the return an investor would earn if they held the bill for a full year.
* Daily Rates Reflect Short-Term Returns: Daily rates represent the interest earned on a daily basis.
Approximation Methods:
* Simple Daily Rate (Approximation):
* Divide the yearly rate by 365 days.
* Note: This is a simplification and may not accurately reflect the actual daily return, especially for longer periods.
* Compounding Daily Rate (More Accurate):
* Calculate the daily compounding factor: (1 + Yearly Rate)^(1/365) - 1
* This method accounts for the effect of daily compounding on the overall return.
Important Considerations:
* Market Volatility: Interest rates fluctuate daily. Daily rates derived from yearly averages may not accurately reflect actual market movements.
* Trading Conventions: The exact calculation methods may vary depending on market conventions and the specific data source.
