30 Mil Réis Banco da República dos Estados Unidos do Brazil, 1st. Print

The Banco da República dos Estados Unidos do Brazil was itself a product of the Encilhamento — the speculative frenzy that followed the 1889 proclamation of the Republic, when the new government's easy-money policy flooded Brazil with credit and paper. This bank was formed in 1890 through the merger of the Banco do Brasil and the Banco Nacional, giving it a near-monopoly on note emission at precisely the moment that monetary chaos was accelerating.

Giesecke & Devrient in Leipzig handled production of this series, a common arrangement for Latin American issuers who lacked domestic security printing capacity. The institution itself collapsed under the weight of the Encilhamento's aftermath, with its note-issuing privileges eventually absorbed into the reorganized Banco da República do Brasil in 1893.
