London: Iran has switched from the US dollar to the euro as its official reporting foreign currency, state media reported on Wednesday.

The decision was taken in a cabinet meeting as the government tries to manage the exchange rates and support the plunging rial and reduce its reliance on the American currency.

Central bank governor Valiollah Seif said last week that Supreme Leader Ayatollah Ali Khamenei had welcomed his suggestion to replace the dollar with the euro in Iran’s foreign trade, as “dollar has no place in our transactions today”.

Tehran has been trying for years to move away from the dollar because of political tensions with Washington, although much of the country’s international trade is still conducted in dollars and ordinary Iranians use them for travel and savings.

US President Donald Trump has threatened to exit a 2015 nuclear deal Iran made with world powers unless it is revised. US sanctions will resume unless Trump issues new “waivers” to suspend them on May 12.

Exposure to sanctions

Bank transactions involving the dollar are already difficult for Iran because legal risks make US banks unwilling to do business with Tehran. Foreign firms can be exposed to sanctions if they do Iranian deals in dollars, even if the operations involve non-US branches.

As a result, France will start offering euro-denominated credits to Iranian buyers of its goods later this year to keep its trade out of reach of US sanctions, the head of state-owned French investment bank Bpifrance said in February.

The threat of US sanctions has destabilised Iran’s foreign exchange market in recent months. The rial lost close to half its value on the free market between last September and last week, sinking to a record low of about 60,000 against the dollar before authorities set a fixed rate of 42,000 and warned Iranians they would face penalties for using other rates.
