What it means
The mechanics are simple to describe. One party buys protection on a reference entity, meaning a named company or government, and pays a premium each quarter expressed as a spread in basis points on the notional amount protected.
If a defined credit event occurs, such as a missed payment or a bankruptcy filing, the protection seller pays out and the contract terminates. The reason it matters to non-specialists is that CDS spreads are the market's live opinion on how likely a company is to fail.
A treasurer watching the spread on their own employer's debt widen from 120 to 400 basis points is watching lenders reprice that credit in real time, often well before a rating agency reacts. Boards therefore track their own CDS spread the way they track their share price.
In use, a CDS can be a hedge or a bet. A bank that has lent $50,000,000 to a manufacturer can buy protection to reduce its exposure without recalling the loan and damaging the client relationship.
An investor with no exposure at all can buy the same protection purely because it expects the borrower to deteriorate, which is known as a naked position. The important nuance is settlement and definitions.
Payouts usually depend on a recovery rate determined by an auction of the defaulted debt, so the protection buyer receives the difference between par and that recovery value rather than the full notional. What counts as a credit event is also defined contractually, and some restructurings have historically fallen outside the definition, leaving protection buyers unpaid despite obvious distress.
In practice
Real-world examples.
Example
A bank with a large loan to an energy producer buys credit protection rather than syndicating the loan, keeping the client relationship intact while reducing the capital it must hold against the exposure.
Example
A corporate treasurer notices the CDS spread on her own company widening sharply after a profit warning and uses it as evidence in a board paper arguing to refinance a bond a year earlier than planned.
Example
A hedge fund buys protection on a chain of department stores it believes is over-leveraged, holding no bonds at all. When the chain restructures its debt, the fund collects on the contract.
Think of it
“CDS is credit insurance-paying a premium for protection if a borrower defaults.
Formula
Calculation
Annual premium = notional amount x spread
Payout on default = notional amount x (1 - recovery rate)
A pension fund buys $10,000,000 of five-year protection on a retailer at a spread of 200 basis points, which is 2%. Its annual premium is $10,000,000 x 0.02 = $200,000, paid as four quarterly instalments of $50,000. Three years in, the retailer files for bankruptcy and the auction sets the recovery rate on its senior bonds at 40%, so the payout is $10,000,000 x (1 - 0.40) = $6,000,000. Over those three years the fund paid 3 x $200,000 = $600,000 in premiums, so its net gain on the contract is $6,000,000 - $600,000 = $5,400,000, which offsets the loss on the retailer's bonds it actually held.Case study
Seen in the real world.
The following is an illustrative and fictional example. Kestrel Mutual is an invented insurance company holding $80,000,000 of bonds issued by a fictional packaging group whose leverage had been climbing for two years. Selling the bonds outright would have crystallised a loss and moved the market against Kestrel, since it held a large slice of a thinly traded issue.
Kestrel instead bought $40,000,000 of three-year protection at a spread of 250 basis points, costing $1,000,000 a year. That halved the effective exposure while leaving the bonds on the balance sheet and the coupon income intact.
Eighteen months later the packaging group missed a coupon payment, the auction set recovery at 35%, and the illustrative payout was $40,000,000 x 0.65 = $26,000,000 against $1,500,000 of premiums paid. The fictional risk committee later noted that the hedge worked, but only because the contract's credit event definition clearly covered a missed payment, and it added a legal review step for future purchases.
Watch out
Common mistakes.
- Describing a credit default swap as insurance in the legal sense, when it is a derivative contract that requires no insurable interest and is not regulated as insurance.
- Assuming the protection seller pays the full notional on default, when the payout is normally reduced by the recovery value of the defaulted debt.
- Reading a widening spread as a certain forecast of failure, when spreads also move with market liquidity, general risk appetite and technical supply and demand.
Questions
People also ask.
What is a basis point in a CDS spread?
One basis point is 0.01%, so a spread of 200 basis points means an annual premium of 2% of the notional amount protected.
What counts as a credit event?
Typically bankruptcy, failure to pay, and in many contracts a defined restructuring, with the exact list set out in the contract documentation.
Who takes the risk if the protection seller fails?
The buyer does, which is why most standardised CDS contracts are now centrally cleared and collateralised rather than left as bilateral promises.
