Treasury Indexed Bonds
Treasury Indexed Bonds are medium to long-term securities for which the capital value of the security is adjusted for movements in the Consumer Price Index (CPI). Interest is paid quarterly, at a fixed rate, on the adjusted capital value. At maturity, investors receive the adjusted capital value of the security – the value adjusted for movement in the CPI over the life of the bond.
All Treasury Indexed Bonds are exempt from non-resident interest withholding tax (IWT).

Treasury Indexed Bonds are issued by tender twice a month in most months, for more information please see Forthcoming Tenders. To receive tender announcements and results via email, you may subscribe to the AOFM email service.
Treasury Indexed Bonds are both quoted and traded on a real yield to maturity basis rather than on a price basis. This means the price is calculated after agreeing on the real yield to maturity. The price is calculated by inputting the real yield to maturity into the appropriate pricing formulae.
The pricing formula used for Treasury Indexed Bonds per $100 face value, rounded to the third decimal place except during the last interest period (the period beginning when a Treasury Indexed Bond goes ex‑interest for the second last time) when there is no rounding, is as follows:
Settlement amounts are rounded to the nearest cent (0.5 cent being rounded up).
As an example of the working of the formula consider the 4.0% 20 August 2020 Treasury Indexed Bond for a trade settling on 31 May 2010. Assuming a real yield to maturity of 2.65 per cent per annum the price per $100 face value is calculated to be $160.144.
In this example, i = 0.006625 (i.e. 2.65 divided by 400), f = 81, d = 92, g = 1.0 (i.e. 4 divided by 4) and n = 40. The K value of this bond () on 20 May 2010 (the previous interest payment date) was 142.65 and the K value () for 20 August 2010 (the next interest payment date) is 143.66. The 0.71 per cent increase in the K value reflects the average increase in the Consumer Price Index over the two quarters to the March quarter 2010.
If the trade was for Treasury Indexed Bonds with a face value of $20,000,000 the settlement amount would be $32,028,800.00.
Ex-Interest Treasury Indexed Bonds
The ex-interest period for Treasury Indexed Bonds is seven calendar days. With ex-interest Treasury Indexed Bonds the next coupon payment is not payable to a purchaser of the bonds. In this case, calculation of an ex-interest price is effected by the removal of the ‘1′ from the term in formula (1), thereby adjusting for the fact that the purchaser will not receive a coupon payment at the next interest payment date. The formula in this instance is therefore:
Note that the in formula (2) is still the indexation factor on the next interest payment date, even though there is no interest payable to the subscriber or purchaser on that date. That is, this continues to apply in the ex-interest period.
