This article offers a new interpretation of the Baring crisis, the most dramatic financial collapse of the nineteenth century, by focusing on how information brokerage allowed Barings to abandon its risk-averse practices in the mid 1880s. I argue that the mediators who bridged structural holes (gaps between social clusters) shaped actors’ access to information as well as their expectations regarding its quality. Information brokers who enjoyed philos ties with at least one of the parties connected by the bridging relationships could promote collaborative arrangements more likely to survive an environment of heightened uncertainty. The performance of such brokers in the 1880s enabled cooperation between Baring Brothers & Co. and the Banque de Paris et des Pays Bas and supported the London house's growing association with the Anglo-Argentine firm of S. B. Hale & Co. in the second half of the 1880s. Cooperation gave Barings an illusion of security amid the costs of increasing competition and supported the house's growing engagement in South American affairs. Nevertheless, the strategy proved ineffective at barring the entry of new players. By the late 1880s, ties produced by brokerage connected Barings to the house's former competitors, producing a cohesive social cluster. Barings thereafter had access to redundant information, which hindered the house's ability to assess risk.
