Suppose 6-month Treasury bills are trading at a YTM of 1.6%, 12-month T-bills are trading at a YTM of 2.9%. If 18-month Treasury notes with a coupon rate of 3% are trading at par ($100), then what is the 18-month spot rate?
Suppose 6-month Treasury bills are trading at a YTM of 1.6%, 12-month T-bills are trading at a YTM of 2.9%. If 18-month Treasury notes with a coupon rate of 3% are trading at par ($100), then what is the 18-month spot rate?
We are given the 6 month spot rate and 12 month spot rate as 1% and 2% respectively. The YTM of the T-bills are the spot rates.
Now we are also given the price of an 18 month T note with 5% coupon as $100 (as it is trading at par).
Price of the T note is the PV of all future coupons and par value discounted at the spot rate.
The formula will be as below:
By rearranging the above formula, we can solve for S3 which is 18-month spot rate. Please note that the spot rates need to be divided by 2 as the compounding is semiannual.
Coupon is computed with the formula below:
Semiannual Coupon = coupon rate/2 x par value
