Quote from bestfriend:
I have some corporates due in 7-30 yrs and I want to hedge out the risk on a good portion using the futures as a proxy. Which should I seel and how much? Say I have $500k in 30 yr aa corpproates and $1 mill in 7-15 yr corporates. I have an IB acct. I want to avoid selling them as they are pretty illiquid.
optioncoach and f-tdr have the right idea, but I would only use this for a short term hedge, ie 1 week or less if you are worried about a short term spike in rates. Over time you will have credit spread, change in deliverables (which will change the duration of the futures contracts, and other issues to worry about.) Also, bond yields have gone up nearly 50bps in the past 3 months, so you might be a little late.
As an example, without knowing the coupon and maturity of your bonds, I could estimate and say the dollar value of 1bp on $1mm 30 year bond is $1404. So your $500k bond would be worth approximately $702 / bp. The $value of the Sept bond futures contract is $106.40 ($val of cheapest to deliver, 7.625 11/2022 = $1232 divided by conversion factor 1.1593 = 106.27) So, you could short 6 or 7 bond futures contracts to hedge your $500k 30yr bond.
As for $1mm of 7 - 15 yr corporates, again a wild ass guess without knowing the coupons or maturities would be an 11yr average worth around $1007/ bp. The 10yr futures contract has a $value of $61.92 per bp. You would probably want to use a combination of 10yr and bond futures, because the 10yr future actually tracks a 5/2014 issue (only 7yr maturity). Anyway, you would short about 16 TYU7 (10yr futures contracts) to hedge your 1mm in corporates. $1007 divided by $61.92.
There are a lot of risks - the most obvious being some type of panic that widens out credit spreads, ie a flight to quality in treasuries, where your corporate bonds could go down while the treasury futures go up, compounding your loss instead of hedging it.
Goldman would probably design you a nice hedge program for 5% of your principal
