Question: 7. Another way to write a duration-based hedge ratio is as follows: Hedge Ratio = CF ctd X (P b X D b ) (1+YTM
7. Another way to write a duration-based hedge ratio is as follows:
Hedge Ratio = CFctd X (Pb X Db) (1+YTMctd) where
(Pf X Df ) (1+YTMb)
CF = conversion factor for CTD bond
Pb = price of bond portfolio as percentage of par
Db = duration of bond portfolio
Pf = price of futures contract as percentage of 100%
Df = duration of CTD bond for futures contract
YTMctd = Yield to Maturity of CTD bond
YTMb = Yield to Maturity of the portfolio (average)
A bond portfolio manager holds a government bond portfolio with a face value of $10 million that is currently worth a market value of $9.7 million. The manager is concerned about future rising interest rates and so decides to hedge with a T-Bond futures contract. The cheapest to deliver bonds have a projected duration at maturity of 11.14 years. Their conversion factor is 1.1529 and at their current price the futures price is 90-22. The projected average duration of the bond portfolio is 9.0 years. Current Yield to Maturity is 7.8% on the portfolio and 7.1% on the CTD bond.
a. Based on the above data, compute the optimal hedge ratio.
b. Based on the interest rate expectations, should they take a short or long position?
c. The optimal number of contracts to hedge with is given by:
Number of contracts = HR X (Portfolio par value/value of futures contract)
Where each futures contract is for $100,000 of bonds.
Based on this, compute the optimal number of futures contracts to hold.
d. The closing futures contract price is 89-16. Based on this, how did the futures position perform?
