Overview

The Currency Commission, known in Irish as Coimisiún an Airgid Reatha, was a monetary institution created by the Currency Act 1927 as part of the Irish Free State's effort to establish a distinct national currency system. Its formation was connected with the creation of the Saorstát pound, the currency of the Irish Free State, and represented an important step in developing the state's financial institutions after independence. The commission's responsibilities included arranging the design and production of banknotes for the new currency. It commissioned the Series A banknotes with the assistance of an advisory commission. These notes formed the first major national banknote series associated with the Irish Free State and later Ireland. The Currency Commission also issued the Ploughman series of banknotes for Irish banks. The Ploughman notes were used as legal tender until 1953, extending their importance beyond the commission's own institutional life. The commission operated during a transitional period in Irish monetary history. The Irish Free State initially retained close links with the British monetary system, while also seeking symbols and institutions that reflected its political independence. The Currency Commission therefore combined practical monetary administration with the creation of a recognizable national currency identity. Its banknote work helped establish visual and institutional conventions that were later continued by Ireland's central-banking authorities. Joseph Brennan served as chairman of the Currency Commission. Brennan was a significant figure in the development of the Irish state's financial administration, and his leadership placed the commission within the broader effort to organize the Free State's monetary and banking arrangements. Following the adoption of the Constitution of Ireland in 1937, the institution became known as the Currency Commission of Ireland, reflecting the constitutional change from the Irish Free State to Ireland. The commission was ultimately superseded in 1942 by the Central Bank of Ireland. Its functions and historical role were thereby incorporated into a more conventional central-bank structure. Although defunct, the commission remains important in the history of Irish currency because it organized early national banknote issues and served as the principal monetary institution of the Irish Free State before the establishment of the Central Bank.

History

The Currency Commission was created under Section 14 of the Currency Act 1927. Its establishment formed part of the Irish Free State's policy of creating the Saorstát pound and building a monetary framework suited to the newly established state. Before this institutional development, Ireland's currency arrangements remained closely connected to the British monetary system. The commission provided a mechanism through which the Free State could administer its own currency while managing the practical requirements of note issue and banking circulation. One of its principal tasks was the commissioning of national banknotes. Working with advice from an advisory commission, it arranged the Series A banknotes. These notes were an important expression of the Free State's monetary independence, combining the technical requirements of a circulating currency with the development of a distinctive Irish design and issuing authority. The commission also issued the Ploughman series of banknotes for Irish banks. Those notes remained legal tender until 1953, several years after the Currency Commission itself had ceased to exist, demonstrating the continuing circulation and institutional significance of its note issues. Joseph Brennan was chairman of the commission. Under its administration, the Currency Commission functioned as the central public body associated with the Irish Free State's currency arrangements. Its role was narrower than that of a fully developed modern central bank, but it occupied a foundational position in the evolution of Irish monetary administration. It helped formalize the process through which banknotes were issued and gave the Free State a recognizable national currency infrastructure. The constitutional transformation of 1937 changed the institution's designation. When the Constitution of Ireland was adopted, the Currency Commission of the Irish Free State became the Currency Commission of Ireland. This change reflected the new constitutional status and terminology of the state rather than a wholly new institution. The commission continued its monetary role until 1942, when it was superseded by the Central Bank of Ireland. The replacement of the Currency Commission marked a further stage in the consolidation of Ireland's financial institutions. The Central Bank assumed the functions previously associated with the commission within a more comprehensive central-banking framework. The Currency Commission is therefore best understood as a transitional institution: it was created to establish an Irish currency authority, oversaw important early banknote series, adapted to the constitutional change of 1937, and was eventually replaced by Ireland's central bank in 1942.
