Credit Derivatives Glossary: CDS, Recovery, Spread and Credit Events

Credit derivatives are contracts that transfer, isolate or repackage specified credit-related risks without necessarily transferring ownership of the underlying bond. The core instrument is a credit default swap (CDS), in which a protection buyer pays agreed amounts and the protection seller may owe a defined settlement after a qualifying credit event. The precise obligations depend on contract terms, not simply whether a company experiences financial distress.

This glossary defines the credit-market language used by corporate bond, sovereign debt and CDS researchers. It distinguishes traded spreads from default probabilities, explains contract settlement and uses a simplified recovery calculation, while highlighting the counterparty and documentation risks that headline quotes often conceal.

Key terms explained

Reference entity

The borrower or other specified entity whose credit-related events are referenced by a CDS. A company issuing several bonds may be a reference entity even though the CDS contract does not necessarily specify one particular bond as the sole deliverable obligation. Contract documentation defines the legal entity, obligations and succession rules; corporate reorganisations and changes in ownership can complicate these definitions.

Reference obligation

A designated debt obligation used in a credit derivative’s documentation, potentially for reference or identification purposes. It is not necessarily the only deliverable security after a credit event, and its role depends on the contract’s definitions. Analysts should distinguish reference obligation from deliverable obligation, because assuming they are identical can misstate settlement economics.

Credit default swap (CDS)

A derivative in which the buyer purchases protection against specified credit events affecting a reference entity or basket and generally pays periodic premium and sometimes an upfront amount. The seller receives compensation for taking that contingent exposure. Unlike a conventional insurance policy, economic and documentation details differ, and the buyer may not hold the referenced debt.

Protection buyer and seller

The protection buyer generally benefits, subject to settlement terms, when a qualifying credit event produces a payout; the protection seller generally bears that loss exposure while receiving the contractual premium. ‘Buying CDS’ usually refers to buying protection rather than buying the underlying issuer’s bond. Positions can be used for hedging or credit speculation and are exposed to market, documentation and counterparty risks.

CDS running spread

The periodic premium rate paid on the CDS notional, commonly quoted in basis points per annum. A spread of 200 bp on £10 million notional corresponds to £200,000 annualised premium before accrual, upfront amounts and other contract details. Quoted CDS spread levels should not be interpreted as direct unconditional default probabilities; expected recovery, discounting, maturity and risk premia all influence pricing.

Standard coupon and upfront payment

Many CDS contracts trade with standardised running coupon conventions while the mark-to-market difference is exchanged as an upfront payment. This means a quoted par spread can differ from the contract’s actual fixed coupon. A buyer may pay or receive an upfront amount depending on market pricing, coupon and whether protection is bought or sold. Check the quoting convention before comparing two dealer screens.

Credit event

A defined occurrence that can trigger CDS settlement. ISDA-style documentation may recognise events such as bankruptcy, failure to pay and, where applicable, restructuring or other precisely specified circumstances. The inclusion of a particular event varies by contract type and region. A missed coupon, restructuring rumour or ratings downgrade does not automatically satisfy every CDS agreement.

Credit event determination

A formal process may be needed to establish whether a qualifying event has occurred under the CDS documentation, including whether notice and settlement requirements are met. Relevant ISDA determinations and contract rules can influence market outcomes. A headline that a borrower is ‘in crisis’ is not a substitute for applying the contract definitions and applicable determinations.

Recovery rate

The percentage of the relevant debt claim’s value ultimately recovered after default or restructuring, under a defined measurement basis. Recovery can differ across secured versus unsecured seniorities and across legal jurisdictions. In a stylised CDS payout model, lower recovery increases potential protection payment. A modelled recovery estimate is not necessarily equal to the final CDS auction settlement price.

Loss given default (LGD)

LGD is the proportion of exposure that is lost after a default, under an explicit recovery assumption: LGD = 1 − recovery rate. If a simplified exposure is £1 million and recovery is 40%, LGD is 60%, giving £600,000 potential loss before recoveries, timing and costs. This is a teaching approximation, not an assurance that an unsecured bond or CDS will settle at 40%.

CDS auction settlement

Following certain credit events, market protocols may employ an auction mechanism to help determine a final price for eligible obligations. That price can feed into cash settlement under contract rules, reducing the need for all participants to physically deliver bonds. Deliverability, seniority and auction mechanics matter; not every debt instrument necessarily qualifies.

Physical versus cash settlement

Physical settlement can require delivery of eligible debt obligations in exchange for the agreed payment, while cash settlement calculates the loss using the contract’s specified price mechanism. Auction settlement is one form of organised price discovery for relevant obligations. In a stressed market, sourcing deliverable bonds, the cheapest-to-deliver option and settlement conventions can affect economics.

Hazard rate and risk-neutral default intensity

Credit pricing models may represent default as an intensity or hazard rate governing conditional default probabilities. A crude illustrative relation is credit spread ≈ hazard rate × LGD under restrictive assumptions. The market-implied rate incorporates risk premia, liquidity and model choices; it is not necessarily an unbiased real-world forecast of defaults. Different tenors and recovery assumptions produce different implied intensities.

CDS index and single-name CDS

Single-name CDS references an identified issuer, whereas an index contract references a standardised basket of entities. Credit index instruments can provide liquid broad protection or exposure with sector and maturity conventions. Index price moves may diverge from a portfolio of single-name CDS because of liquidity, standardisation, defaults, composition and index-versus-single-name basis.

Jump-to-default exposure

Jump-to-default risk is the discontinuous loss if a reference entity suddenly defaults or a credit event triggers large repricing. A position may show modest daily spread volatility until a major credit event. Hedging with spread duration alone does not remove this jump risk, and multiple reference entities may default together during a severe macroeconomic shock.

Worked example

Assume a fictional CDS has £5 million notional and a qualifying credit event produces an applicable final settlement price of 35% of par. Under the stylised loss settlement, protection payment ≈ £5m × (1 − 0.35) = £3.25 million. Actual payments depend on accrual, settlement method, deliverable obligations, contract terms and any prior payments. The example isolates the loss component rather than modelling the entire trade.

Suppose the CDS running premium is 150 bp, or 1.5% per annum, on the same £5 million notional. A simple annualised premium amount is £75,000, before contract accrual dates, upfront amounts and fee adjustments. The protection buyer may pay premiums for years without a credit event. A seller may earn those premiums but face a loss far exceeding one year’s receipts if an event occurs.

At an assumed recovery of 40%, a simple spread-based intensity approximation for a hypothetical 300 bp spread is 0.03/0.60 = 5% per annum. That is not a statement that the issuer has precisely a 5% annual objective probability of default, nor that defaults are independent over time. It is a simplified risk-neutral relation that omits liquidity and other pricing details.

How professionals use these terms

Credit desks monitor spread changes alongside bonds, ratings actions, issuer leverage, liquidity, covenant headroom and refinancing calendars. A CDS spread widening may indicate rising demand for protection, deteriorating issuer fundamentals or general credit-market stress. The interpretation requires comparison with similar tenors, seniorities, dealer liquidity and the issuer’s cash bond spread.

Portfolio managers can use CDS to reduce or increase defined credit exposure without selling the cash bond, though the hedge can be incomplete. The bond and swap may refer to different seniorities or restructuring terms, creating basis risk. A portfolio of issuer names also faces correlation and concentration risk; buying protection on a few names does not eliminate all downside in a systemic credit event.

For due diligence, retrieve the trade confirmation, ISDA definitions, reference entity, obligation category, credit events, maturity, coupon, upfront quote, settlement conventions and available collateral arrangements. The exact contract is more informative than a news headline that calls CDS ‘insurance against bankruptcy’.

Common interpretation errors

A CDS ‘spread of 200’ almost always needs the unit—commonly basis points per annum—and a clear distinction between quoted spread and standard coupon. A credit-rating downgrade is not universally a settlement-triggering event. Do not assume an investment-grade corporate bond and a CDS on the same name have exactly the same deliverables, maturity risk or legal seniority.

The approximation spread ≈ default intensity × loss given default is not a universal empirical law. Recovery varies and default pricing embeds risk premia. CDS also exposes investors to market liquidity, counterparty and collateral risks; the apparent protection may be less effective precisely when the underlying credit event becomes most disruptive.

At-a-glance comparison

Frequently asked questions

Does buying CDS mean buying the company’s bonds?

No. Buying CDS typically means buying a derivative contract for credit protection rather than owning the cash debt.

Does a rating downgrade trigger CDS settlement?

A downgrade alone is generally not sufficient; the contract must define a qualifying credit event.

Is the CDS spread a default probability?

No. Recovery assumptions, timing, liquidity, risk premia and modelling all influence the quoted spread.

What happens after a qualifying credit event?

Settlement follows the contract and applicable determination or auction procedures; the payout can depend on recovery pricing.

Can CDS buyers lose money without a default?

Yes. Paid premiums, spread changes, collateral and transaction costs can produce losses even if no event occurs.
