Market Data • T-Bills • 26W 0.130% • 52W 0.175% • T-Note • 2 year • Coupon rate 0.25% • Semi-Annual Yield 0.273%
T-NotePricing • As there are 4 cashflows in a 2-year T-Note we need 4 discount factors to price the note • These are the 6M, 1Y, 18M and 2Y • We could simply use the s.a. yield to determine a PV but we do not get any term structure information from this. • For example, short term rates are lower than longer term rates. The T-Note price gives information about the relationship but we cannot determine that information from the s.a. yield directly.
Goal • In order to view the yield curve we need to look at consistent rates. • The natural choice for rates is the YTM for a discount bond for a given maturity • An alternate view would be to look at Expected 6M T-Bill prices for 6M, 1Y and 18M. • We need enough rates to value a 2 year T-Note • The rates we need are the 6M, 1Y, 18M and 2Y rates
What we already know • Given the T-Bills we can easily compute the 6M and 1Y YTM. • We can also easily compute the discount factor for a cashflow received on these dates.
What we need to figure out • To create the yield curve we are trying to • Come up with the yield to maturity for 18M and 2Y • Come up with forward T-Bill rates (the first is straightforward) • Start date 6M, 1Y, 18M • End date 12M, 18M, 2Y • These are equivalent representations
Forward T-Bill rates • To figure out Forward T-Bill rates we need • Forward discount factors • Represent the value of 1 dollar paid at the end date as of the start date
Forward T-Bill Rate • The expected Discount Rate for the 6M T-Bill starting in 6M time is straightforward
The Problem • We still need to find two rates • Expected T-Bill starting in 12M and maturing in 18M • Expected T-Bill starting in 18M and maturing in 24M • Alternatively • Expected YTM for 18M • Expected YTM for 24M
The Problem cont • We have a single equation that we have not used. • Or alternatively – we have three pieces of market data and 4 unknowns necessary for pricing our T-Bond
Assumption • We will assume that the 6M T-Bill starting in 12M time will have an expected discount rate that is the average of the 6M T-Bill starting in 6M time and the 6M T-Bill starting in 18M time
Pricing the T-Note • If you price using discount factors you find • Otherwise you use a standard s.a. yield calculation
Discount Factors • The missing discount factors can be derived from: • The missing discount factors from these equations can be derived from the T-Bill discount ratediscount factor formula
Final Solutions • We then use the solver from excel to price the T-Note using discount factors and using s.a. yield calculation and iterate on the T-Bill prices until they match.
