The Oriental Bank Corporation was a British overseas bank chartered in Bombay in 1842, later headquartered in London, and by the 1860s operating across Ceylon, India, China, and Australia. Its Galle branch issued private banknotes at a time when no government currency authority existed for Ceylon — these were genuinely circulating commercial instruments, not government scrip. The bank collapsed catastrophically in 1884, a failure driven largely by bad loans tied to falling commodity prices across its Asian branch network.

Notes from the Galle branch are rare precisely because the failure triggered immediate recall and destruction of outstanding paper. Survivors almost certainly escaped redemption through loss, hoarding, or abandonment in the chaos following the bank's closure.
