Finance term
Credit Default Swap (CDS)
Also known as: CDS, credit default swap
Definition
A credit default swap (CDS) is a bilateral derivatives contract that transfers the credit risk of a reference entity (a company or sovereign) from the protection buyer to the protection seller — the seller pays the buyer if the reference entity defaults or experiences a specified credit event. CDS contracts are governed by ISDA documentation and central counterparty clearing (CCP) requirements under Dodd-Frank.
Detailed explanation
A CDS functions as insurance on credit risk. The protection buyer pays a periodic premium (the CDS spread, quoted in basis points per year on the notional amount) to the protection seller. If the reference entity (the company whose debt is being hedged) experiences a credit event — default, bankruptcy, restructuring — the seller compensates the buyer, typically by delivering the par value of the defaulted obligation.
CDS are governed by ISDA Credit Derivatives Definitions, which specify qualifying credit events. Since Dodd-Frank (2010), standardized single-name and index CDS must be cleared through a central counterparty (CCP) such as ICE Clear Credit, reducing bilateral counterparty risk. The DTCC's Trade Information Warehouse reports outstanding CDS notional to regulators, with aggregate data available through the BIS (Bank for International Settlements) at https://www.bis.org/statistics/derstats.htm.
For lending context, CDS spreads serve as real-time market signals of a company's default probability. A widening CDS spread (higher cost to insure against default) signals deteriorating credit quality — often before rating agencies downgrade. Banks and institutional lenders track CDS spreads on their large corporate borrowers as a leading indicator. For SBA and small business lending, CDS are not directly applicable — they trade on large publicly rated issuers, not private SMBs — but understanding CDS pricing logic helps contextualize corporate credit risk premiums that cascade into small business lending markets.
◈ Worked example
- Protection buyer pays 150 bps/year on $10M notional CDS referencing a corporate bond issuer. Annual premium: $150,000. If the issuer defaults, buyer receives $10M (minus recovery value).
- CDS spread on a speculative-grade issuer widens from 300 bps to 600 bps over 3 months → market is pricing in significantly higher default probability.
- Index CDS (CDX.NA.IG) tracks 125 investment-grade North American names — used by banks to hedge a portfolio of corporate credit exposures in aggregate.
Common questions
The most-asked questions about Credit Default Swap (CDS) — answered straightforwardly.
How did CDS contribute to the 2008 financial crisis? +
CDS on mortgage-backed securities (MBS) and collateralized debt obligations (CDOs) allowed institutions to build concentrated exposures to housing credit risk without holding the underlying bonds. When housing defaults surged, CDS sellers (notably AIG) faced catastrophic payouts they couldn't cover. The crisis revealed the systemic interconnectedness of OTC derivatives — which led to Dodd-Frank's central clearing mandates for standardized CDS to reduce counterparty risk.
What is the CDS spread telling me? +
The CDS spread (in basis points per year) is approximately the market's implied annual default probability discounted by expected recovery rates. A 200 bps CDS spread on a 5-year contract on an investment-grade issuer roughly implies the market assigns a ~3-4% cumulative default probability over 5 years (varying by recovery assumption). Wider spreads = higher perceived default risk.
Are CDS regulated? +
Yes. Dodd-Frank (2010) brought major CDS reforms: standardized index and single-name CDS must be cleared through CCPs, reported to swap data repositories, and executed on registered swap execution facilities (SEFs). The CFTC has primary oversight of most CDS under Title VII of Dodd-Frank. Bank regulators (OCC, Federal Reserve) supervise dealer banks that write CDS under capital and risk requirements.
