Mazaheri said CBI’s earlier decision on April 10 to fix the US dollar’s exchange rate at 42,000 rials signified the denial of secondary market, but its new measures indicates its will to establish a relative stability in the market, IBENA reported. Secondary market dealings take place through the Forex Deals Integrated System, an online system locally known by its acronym Nima. Although dealings only took place at the fixed rate of 42,000 rials, the government gradually eased the rules so that exporters and importers could trade at “negotiated” rates between themselves, Financial Tribune reported.
