Exporters can't do barter, so our costs are higher. Our dollar is worth IR6,800, their dollar is worth IR8,200. The Iranian ports of Bandar Lengeh, Beshehr, Bandar Khamir and Chah Bahar all do a thriving trade in bartered goods. With official exporters able to get the real value of their dollar, the trade with these ports will collapse. But while the abolition of sanctions could change the nature of the UAE's trade drastically, there is an upside.
Iranian ports are in a sorry state.
Years of neglect and nepotism have meant some goods cannot be exported at all. You don't want to lose all your money on freight charges. Any major growth in Iranian exports and imports will perforce have to come through Dubai. With merchants estimating it will take as many as five years for trade relations to normalise, the UAE could benefit tremendously. For the first few years people will still use Dubai.
