Regulated Market

The market is seen as a government measure to restore some discipline to the chaotic currency market. It was created to organize an open and transparent system where currency is traded via an electronic platform. Central bank officials say this market has delivered in controlling the currency market.
"The regulated market has been successful in disciplining the currency market because the number of illegal deals has considerably decreased in the past two years," Akbar Komijani, the CBI vice governor, was quoted as saying in a meeting with the Regulated Market Company officials on Tuesday.
In April 2018 a company was created to supervise the regulated market. It is a private enterprise comprising major stakeholders, namely the Association of Private Banks and Credit Institutions, Association of Bureaux de Change Operators, representatives of public banks, Iran Fara Bourse (the junior market for securities and other financial instruments).
It managed dollar deals worth $1 billion in two years. Deals worth € 176 million were made via the regulated market, Komijani said.
