The World Federation of Exchanges has published a paper, Key Attributes of Exchanges: Harnessing Network Effects, arguing that network effects are a defining feature of public markets and underpin their effectiveness, with implications for public policy. The paper describes exchanges as “all-to-all” networks that bring a broad range of participants into transparent, rules-based markets, concentrating liquidity, strengthening price discovery and supporting investor protection and overall market quality. It also links exchanges’ network effects to scalability, innovation and operational resilience, and highlights how central counterparties reinforce these benefits through multilateral netting and counterparty risk management, supporting stability and more efficient use of capital. The WFE flags risks from fragmented market structures, noting that dispersing trading activity across less transparent or bilateral channels can weaken network benefits and adversely affect liquidity, price formation and market quality.
