The Banco Nacional del Perú maintained a branch in Iquique — spelled "Yquique" in period usage — that operated in what was then Peruvian territory. The city passed to Chilean control following the War of the Pacific (1879–1884), and any notes tied to this branch effectively became stranded obligations of a foreign-administered bank operating in occupied territory. The branch's note issues are consequently rare, not because they were well-hoarded but because the political disruption severed normal circulation and redemption channels.
