Institut Monétaire Luxembourgeois



The Institut Monétaire Luxembourgeois (IML, lit. 'Luxembourg Monetary Authority') was the central bank of Luxembourg between its creation in 1983 and mid-1998, when its role was taken over by the newly created Central Bank of Luxembourg and Commission de Surveillance du Secteur Financier.

Background
During the 19th century, multiple currencies from other jurisdictions circulated and were accepted in Luxembourg. From 1856, the Banque Internationale à Luxembourg was authorized to issue banknotes, which it did in Belgian francs, Dutch florins, Prussian thalers, and Rhenish thaler. Another institution, the Banque Nationale du Grand-Duché de Luxembourg, was chartered to issue notes in 1873. From 1877 until its failure in 1881, it was located in the Hôtel de Gerden on the city's central Place d'Armes, lately the seat of the Court of Accounts of Luxembourg.

From 1918, Luxembourg in principle had a national currency, the Luxembourg franc, but the Belgium–Luxembourg Economic Union established in 1921 resulted in the Belgian franc being widely used in the country. From 1936 on, the National Bank of Belgium maintained a permanent office in Luxembourg City, delivering central banking services directly to economic agents there. These arrangements were suspended under the German occupation of Luxembourg during World War II but re-established in 1944 following the country's liberation.

In 1945, Luxembourg established its first banking supervisory authority, the Commissariat au Contrôle des Banques, at the time partly with the aim of deterring penetration of the domestic credit system by German banks.

Creation and development
In 1983, following frictions within the Belgium–Luxembourg Economic Union, and as the prospect of a future European Monetary Union became gradually more tangible, the Werner-Thorn-Flesch Ministry decided to create the IML so that Luxembourg would be represented on an equal basis with other European countries in forthcoming negotiations about monetary arrangements. The IML printed banknotes, even though it did not conduct a monetary policy of its own, and also succeeded the Commissariat au Contrôle des Banques by taking over financial sector supervision. Pierre Werner, who in 1969-1970 had led the so-called Werner Plan for monetary union, was instrumental in the IML's creation in 1983.

In 1993, the Luxembourg government approved new legislation to carry out the transition from the ad hoc IML to a fully-fledged central bank satisfying the governance criteria set in the Maastricht Treaty.

In March 1998, the IML acquired the former head office of Banque Internationale à Luxembourg on 2 Boulevard Royal, which would become the seat of the soon-to-be-created Central Bank of Luxembourg.

Aftermath
On 1998/06/01, the IML was replaced by the Central Bank of Luxembourg that became a founding member of the Eurosystem, while its supervisory role was transferred to a separate authority, the Commission de Surveillance du Secteur Financier.
