View source for Definition:Bid-ask spread

📋 '''Bid-ask spread''' is the difference between the price a buyer is willing to pay (the bid) and the price a seller is willing to accept (the ask) for an insurance-linked financial instrument, such as a [[Definition:Catastrophe bond (cat bond) | catastrophe bond]], [[Definition:Insurance-linked security (ILS) | insurance-linked security]], or block of [[Definition:Renewal rights | renewal rights]]. In insurance [[Definition:Capital markets | capital markets]], this spread reflects liquidity conditions, the complexity of the underlying risk, and the degree of uncertainty around expected [[Definition:Loss | losses]].

📊 When a [[Definition:Cat bond | cat bond]] trades on the secondary market, the bid-ask spread signals how easily investors can enter or exit a position. Thinly traded tranches—especially those covering [[Definition:Peak peril | peak perils]] or nearing maturity with an active event season—tend to carry wider spreads because fewer counterparties are willing to transact. Market makers and specialized [[Definition:Broker | brokers]] facilitate price discovery, but unlike equity markets, the secondary market for insurance-linked instruments remains relatively illiquid, so spreads can widen sharply after a major [[Definition:Catastrophe | catastrophe]] or during periods of heightened model uncertainty.

🔍 Understanding bid-ask spreads gives [[Definition:Reinsurance | reinsurance]] portfolio managers and institutional investors a practical gauge of market sentiment and transaction costs. A narrowing spread often accompanies increased investor appetite for insurance risk, while a widening spread may indicate stress or repricing after loss events. For insurers exploring [[Definition:Alternative risk transfer (ART) | alternative risk transfer]] mechanisms, tracking these spreads is essential to timing issuances and evaluating whether capital markets solutions are cost-competitive with traditional [[Definition:Reinsurance | reinsurance]] placements.
