What is specific wrong-way risk in counterparty credit exposure, and can you give a concrete example of how it amplifies losses?

Specific wrong-way risk (SWWR) occurs when there is a direct causal or structural link between the counterparty's creditworthiness and the derivative exposure — not merely a statistical correlation, but an inherent economic connection that guarantees adverse co-movement.\n\nSpecific vs. General Wrong-Way Risk:\n\n| Type | Mechanism | Example |\n|---|---|---|\n| Specific (SWWR) | Direct structural link | Buying a put on the counterparty's own stock |\n| General (GWWR) | Macro correlation | Emerging market counterparty in an FX forward |\n\n`mermaid\ngraph TD\n A[\"Wrong-Way Risk\"] --> B[\"Specific WWR

Unknown to Thornbury, Marsten holds a $4 billion concentrated loan portfolio to Glenmark.\n\nScenario unfolds:\n1. Glenmark enters financial distress — its bond spreads widen from 200 to 1,400 basis points\n2. The CDS mark-to-market surges in Thornbury's favor (the protection is now extremely valuable)\n3. The CDS MTM reaches $8.2 million — this is exactly when Thornbury needs Marsten to pay\n4. But Marsten's $4 billion loan to Glenmark is simultaneously deteriorating, threatening Marsten's solvency\n5. Marsten's credit rating is downgraded from A to BB+\n6. If Marsten defaults, Thornbury loses both the CDS protection AND faces a counterparty loss on the $8.2 million receivable\n\nThe CDS protection is most valuable precisely when the counterparty is least able to honor it — the textbook definition of specific wrong-way risk.\n\nQuantifying the Impact:\n\nStandard CVA models assume independence between exposure and counterparty default:\n\nCVA_standard = integral of EE(t) x PD(t) x LGD dt\n\nWith wrong-way risk, the conditional exposure given counterparty default is much higher:\n\nCVA_WWR = integral of EE(t | default at t) x PD(t) x LGD dt\n\nEE(t | default at t) >> EE(t) for wrong-way positions\n\nIn our Thornbury example, the standard CVA might be $180,000, but the wrong-way CVA could be $620,000 or more — a 3.4x multiplier.\n\nRegulatory Treatment:\n\nBasel III/IV requires banks to identify and flag specific wrong-way risk exposures. Such trades receive punitive treatment: either full collateralization, exclusion from netting sets, or a stressed exposure calculation that assumes maximum co-movement.\n\nStudy counterparty credit risk modeling in our FRM Part II course.
