Counterparty risk

Counterparty risk is the risk that the other party to a financial contract will default before fulfilling its obligations, leaving the non-defaulting party with an unhedged exposure and a legal claim of uncertain value. It is the fundamental risk of trust in financial markets — the risk that a promise to pay will not be kept. In bilateral markets, counterparty risk accumulates opaquely across a dense web of interbank exposures, making it impossible for any participant to assess the true risk of the system. The 2008 crisis demonstrated that counterparty risk is not merely a bilateral concern but a network property: the solvency of each node depends on the solvency of its neighbors, and the network as a whole can collapse when trust evaporates. The shift to central clearing was the regulatory response, though it substitutes distributed counterparty risk for concentrated hub risk — a tradeoff whose systemic consequences are still unfolding.
