Azerbaijan, Baku, Oct.7/ Trend F.Milad/
U.S. dollar price was offered at the price of 25,650 rials in Iran's Foreign Exchange Center.
The Forex Center had offered dollar at 25,970 rials on Saturday, The Mehr News Agency reported.
Euro was also offered at 33,432 rials, compared to 33,850 rials the day before, respectively.
On Wednesday, a number of people held a demonstration near the Grand Bazaar of Tehran, using the sharp fall in the value of the Iranian rial as a pretext.
According to reports, businessmen are unhappy about the performance of the administration in regulating the foreign exchange market, saying it has caused instability in prices.
The new Foreign Exchange Center was officially inaugurated on September 24 and some 1,000 applications have been registered at the center.
The new center allows importers of goods including truck tires, construction equipment and synthetic fibers to buy dollars at a rate 2 percent cheaper than the street rate at any given time.
The government maintains an official reference rate of 12,260 rials to the dollar, but only a limited amount of foreign exchange is available at this rate.
Iranian government plans to use revenues from petrochemical sales and 14.5 percent of its oil revenues to provide dollars for the center, central bank governor Mahmoud Bahmani said. He did not give an absolute figure for the amount of dollars to be supplied.
"With the distribution of currency in this center, the exchange rate in the market will go down, because some of the demand (for dollars) will be met in this center and the pressure of demand will be removed," Bahmani was quoted as saying.
