The Institut d'Émission des Départements d'Outre-Mer (IEDOM, ) is a French public financial institution based in Paris which serves overseas departments and overseas communities, namely Guadeloupe, Guyana, Martinique, Mayotte, Réunion, Saint Barthélemy, Saint Martin, and Saint-Pierre-et-Miquelon. Initially established in 1959 as spin-off bank of issue from the Caisse Centrale de Coopération Économique (CCCE), it was gradually brought into the orbit of the Bank of France of which it has been a fully-owned subsidiary since 2017. The IEDOM has thus self-described as a "delegated central bank". It is managed jointly with the Institut d'Émission d'Outre-Mer (IEOM), which is still a bank of issue and serves the French Pacific territories. 
Overview.
Before World War II, monetary issuance in France's overseas territories was carried out by chartered private banks, namely the Banque de la Guadeloupe in Pointe-à-Pitre, Banque de la Guyane in Cayenne, Banque de la Martinique in Fort-de-France, and Banque de la Réunion in Saint-Denis. Their monetary role was taken over on by the Caisse Centrale de la France d'Outre-Mer, renamed in 1958 the Caisse Centrale de Coopération Économique, which issued French francs in Guadeloupe, Guyana and Martinique, and CFA francs in Réunion and also in Saint-Pierre-et-Miquelon.
The IEDOM was spun off from the CCCE in January 1959 to serve Guadeloupe, Guyana, Martinique, and Réunion, still issuing CFA francs in the latter. It was established as a stand-alone government agency under public law (), with human resources and other functional areas managed jointly with the CCCE. On , the IEDOM ceased to print its own French franc notes and instead distributed the Bank of France's notes; on the same date, the French franc replaced the CFA franc in Réunion. On , IEDOM extended its scope of activity to Saint-Pierre-et-Miquelon.
In 1998 in preparation for Economic and Monetary Union of the European Union, legislation was enacted to ensure independence of the IEDOM's monetary policy and alignment with the European System of Central Banks. The legislation stipulated that IEDOM would operate "in the name, on behalf of and under the authority of the Bank of France". Later in 1998, its geographical scope was extended to Mayotte, with effect on . Since then, the chief executive () of IEDOM has been appointed by the governor of the Bank of France, even though the IEDOM was still managed in a joint framework () together with the Agence Française de Développement (successor to the CCCE) and the IEOM. Since September 2006, IEDOM and IEOM have shared a single headquarters () in Paris, with integrated management of common functional areas.
In 2016, new legislation complemented the 1998 reform by bringing IEDOM fully into the orbit of the Bank of France. In order to preserve its personnel policies that favor hiring locals in the relevant territories, IEDOM was not fully merged into the Bank of France but instead was purchased by the Bank of France and transformed into a fully-owned joint-stock company (). This change was endorsed by the European Central Bank as further aligning the French framework with monetary policy independence, and became effective on .
In May 2018, the seat of IEDOM (and IEOM) was relocated from 164, rue de Rivoli in the Louvre Saint-Honoré building to 115, rue Réaumur in central Paris.
