Why Iran is removing four zeroes from its currency: The reason behind the major reform

Iran is set to remove four zeros from its national currency, the rial, in a major redenomination effort aimed at tackling years of high inflation and a severely depreciated currency. Under the proposed plan, 10,000 old rials will be replaced by 1 new rial, effectively cutting four zeros from the currency. For example, what previously cost 1,000,000 rials would now be 100 new rials, making transactions simpler and easier to understand. The reform aims to streamline daily financial transactions, eliminate pricing confusion, and restore public confidence in Iran’s currency amid years of economic challenges and international sanctions.
Iran’s chronic inflation and currency depreciation
Iran’s inflation rate has remained extremely high for many years, worsened by recurring international sanctions tied to its nuclear program. According to reports, on the black market, the rial’s value has plummeted to over 1,100,000 rials per US dollar, making everyday transactions cumbersome. This redenomination seeks to simplify financial operations and make the rial more practical for citizens and businesses.


Usability and transaction simplicity
Before the change, routine purchases often involved millions of rials. With four zeros removed, prices will now be expressed in smaller, more manageable numbers. This makes accounting, price labeling, and government administration easier while reducing errors and confusion in daily transactions.


Economic symbolism
Redenomination is also symbolic. By introducing a simplified currency, Iran aims to signal economic stability and demonstrate a commitment to broader financial reforms to both citizens and international observers.


Alignment with local practice
Iranians often already use the toman, which equals 10 rials, in daily conversation, effectively dropping a zero informally. Officially removing four zeros brings the legal currency in line with everyday practice, reducing confusion and making transactions more intuitive.


Implementation details
The transition will allow both old and new rials to circulate for up to three years. The Central Bank has two years to implement the change fully. However, the reform still requires approval from Iran’s Guardian Council and must be signed into law by President Masoud Pezeshkian. Earlier attempts, such as in 2019, were delayed due to political and economic complications.

The move comes amid renewed UN sanctions and increasing isolation from international financial systems. European parties to the 2015 nuclear deal recently triggered the “snapback” mechanism, weakening the rial further. Many Iranians have already adjusted to using the toman, so the official redenomination is expected to be widely accepted and less disruptive.
