How to hedge Total return swap using CDS?
According to the FRM methodology, a CDS hedges credit default and (if market to market) credit deterioration risk; i.e., credit risk. But a CDS does not (cannot) hedge market risk itself, and therefore a CDS cannot hedge total return (total return is a function of exposure to credit and market risk).
Rather it is the total rate of return swap (TRS or TROR) instrument which hedges against total return.
This means that, although a "naked" CDS (ie., long or short a CDS only) does NOT hedge total return, the CDS plus a long/short position in the underlying does hedge total return. That is:
If underlying exposure is long (owning) the asset, then a total return hedge is given by:
Long a M2M CDS (i.e., hedging credit risk) on the underlying plus short a risk-free asset (i.e., hedging market risk). If interest rates increase, the drop in value of underlying is hedged by increase in value of short position in the risk-free asset.
protection buyer in TRS/TROR (aka, payer) can hedge with:
Short CDS + long RF asset
i.e., TRS payer is short credit risk & market risk, which is hedged by short CDS (long credit) and long RF asset
protection seller in TRS/TROR (aka, receiver) can hedge with:
Long CDS + short RF asset
i.e., TRS receiver is long credit risk: if reference defaults, long CDS hedges the loss.
Also, TRS receiver is long market risk: if rates increase, the TRS receiver's loss on the value decline is hedged by the short position in RF asset.
I hope that helps, thanks!
Thanks for your reply. It really helped a lot.
Referring to 209.2C, the TRS payer position is economically most similar to C. Short a credit risk free asset plus long a CDS (based on the solutions); the solutions go on to say "long CDS hedges credit risk and short risk free rate hedges market (interest rate) risk." Unless I am misunderstanding something, this contradicts the above. If I understand correctly to hedge against the credit risk of TRS (i.e. hedge the potential failure of the protection seller to make interest payments) you long a CDS; assuming the underlying pays a fixed rate of interest, your only other exposure is market risk associated with an increase in value of the reference asset which you would hedge by a call option. Can you please clarify?
Hi @andred0250_ I'm not following you, sorry, and I don't see the discrepancy between my comment above and question 209.2; the source to this question 209.2 is located here at https://www.bionicturtle.com/forum/...ivatives-total-return-swaps-topic-review.6217 and includes my subsequent clarifying comment:
... my comment above is a full decomposition, but as far as I can tell, 209.c and this thread are consistently asserting:
TSR Payer (aka, protection buyer) = long CDS + short risk-free asset (209.2); which is the same as above:
"then a total return hedge is given by: Long a M2M CDS (i.e., hedging credit risk) on the underlying plus short a risk-free asset (i.e., hedging market risk)" and please note the following is hedge: "protection seller in TRS/TROR (aka, receiver) can hedge with: Long CDS + short RF asset"
In neither case, is the CDS or TSR counterparty risk hedged, as this concerns replication of the TSR (and I don't see why the call option needs to enter, sorry). I hope that's helpful,
