Banco de Occidente was a Colombian-chartered bank operating branches across Central America in the late nineteenth century — its Guatemala branch issued currency with full authority under Guatemalan banking concessions of the period. The arrangement was commercially pragmatic: foreign-chartered banks could obtain note-issuing rights in Guatemala provided they maintained specie reserves, which few reliably did.

ABNC's New York plates were shared across multiple Latin American clients, which occasionally produced near-identical design frameworks appearing under entirely different issuing names. Whether that applies to this series specifically is worth checking against contemporaneous Colombian and Guatemalan ABNC contracts.
