Your Guide to Understanding Yield Basis Calculation

Delve into the intricacies of the yield basis, a fundamental method for quoting the price of fixed-income securities. Learn how it simplifies bond comparison, the nuances between yield and net yield basis, and special considerations when purchasing bonds.

The Basic Yield Basis Explained

The yield basis is a method employed to quote the price of a fixed-income security as a yield percentage rather than as a dollar value. This approach provides an easier way to compare bonds with different characteristics. The formula used to calculate the yield basis is the annual coupon amount divided by the bond’s purchase price.

Key Insights

  • The yield basis method quotes the price of a fixed-income security as a yield percentage, enhancing comparability across bonds.
  • It enables swift and straightforward comparisons of various bonds by potential buyers.
  • Yield quotes help bond traders determine if a bond is trading at a discount or a premium.
  • When purchasing on a net yield basis, the yield includes the broker’s profit or markup.

Grasping Yield Basis: An Example

Unlike stocks quoted in dollars, bonds are often quoted on a yield basis. For instance, consider a company with a 6.75% coupon rate, maturing 10 years from issuance, and a $1,000 par bond trading at $940. The yield basis is calculated using the current yield formula:

Coupon Amount / Purchase Price

In this example:

  • Annual coupon: 6.75% of $1,000 = $67.50
  • Yield basis: $67.50 / $940 = 0.0718 or 7.18%

tlquote Treasury BillsWith a yield basis of 7.18%, it is evident the bond trades at a discount due to the higher yield basis compared to the 6.75% coupon rate.

Mastering Bank Discount Yield

For pure discount instruments, the bank discount yield formula calculates the yield basis:

r = frac(Value_from_Par (360 / t) ) where

r = Annualized yield
Value_from_Par=(Discount_between_<=Par_Value<= purchase_price)`

t designated remaining time-period t
