Banks will allocate the US dollar needed for imports at a rate of 42,000 rials when their order registration process is complete, ISNA quoted Ali Aliabadi as saying. Iran unified its dual exchange rates—one official and the other the free market rate—on April 10 at the fixed rate of 42,000 rials. The rate was fixed to prevent the further depreciation of rial, which had lost close to half its value on the free market since September. Importers have since complained about shortage of hard currency and the volatile state of their businesses due to the shutdown of Iran’s import order registration website, Financial Tribune reported.
