TBILLYIELD
Returns the yield for a US Treasury bill.
Syntax:
TBILLYIELD(settlementdate; maturitydate; issueprice)
- settlementdate: the settlement (purchase) date of the Treasury bill.
- maturitydate: the maturity (redemption) date of the Treasury bill.
- issueprice: the issue price of the Treasury bill per $100 of par value.
- A Treasury bill is a short term (up to a year) Government security, sold at a discount to its par value (face value). It pays no interest and is redeemed at par value.
- The Treasury bill here has a 360 day year basis.
- The yield is calculated as:
- ( (100 - issueprice) / issueprice ) * (360 / number_of_days_in_the_term)
- where number_of_days_in_the_term are the actual number of days between settlementdate and maturitydate.
- An error results if the term given is not less than one year.
Example:
TBILLYIELD("2008-07-14"; "2009-01-14"; 96)
- returns approximately 0.0829, or 8.29%.
