On the paper the "Autorité de Régulation du Secteur de la Microfinance» - ARSM" (the Regulatory Authority of the Microfinance Sector), established by law in Niger, is both original and powerful. Indeed, it is rare that this financing mechanism be regulated by a body that is its own and the Decree of 27 March 2007 that created gives it the powers to deliver licenses, permits to exercise, to disseminate information, to monitor the " Systèmes Financiers Décentralisés"- SFD (Decentralised Financial Systems), to conduct inspections and sanction. But in reality, the economic culture of savings failed in Niger and political instability made goes away a few foreign cooperative banks which had supplemented the lack of conventional banks. The Authority also requests that the public authorities, managers of the structures of micro-credit clean up the sector, before injecting any new money.
