CBI Further Tightens Currency Regulations 

The central bank has stopped allocating forex to importers who buy currency from the free market before applying for foreign currency at cheaper prices.
In a letter to his deputy for forex affairs, the governor of the Central Bank of Iran, Mohammad Reza Farzin, reiterated the need for implementing measures to manage the exchange rates in the unofficial market.
"Based on information on how some importers purchase foreign currency, giving currency to companies that buy forex from the free market before the allocation of cheaper resources is prohibited as of Sunday," the CBI website quoted Farzin as saying. 
Henceforth currency will not be allocated without the approval of the CBI chief.
