The Iranian rial has effectively collapsed to zero

Iran’s national currency is going through one of the most dramatic episodes in its history. Against the backdrop of ongoing protests, sanctions pressure, political instability, and growing international isolation, the Iranian rial has reached a state of effective collapse against the world’s key currencies.

According to exchange-rate aggregators, including Google, the rial, when converted into euros, is displayed as 0.00 EUR. Formally, 1 Iranian rial is currently worth approximately 0.0000010 US dollars, 0.00000086 euros, and 0.000079 rubles. These values fall beyond the standard level of precision used by most financial services, which is why they appear as zero in user interfaces.

The reasons for such a sharp depreciation are complex. Iran has been under strict international sanctions for many years, limiting its access to financial markets, foreign currency reserves, and international settlements. This has been compounded by an internal political crisis, chronic inflation, currency shortages, growing distrust in the banking system, and new waves of mass protests. An additional factor has been rising geopolitical tensions and Tehran’s role in external conflicts, which has further narrowed the country’s room for economic maneuvering.

It is important to understand that the claim that the rial “is worth 0 euros” is technical rather than economic in nature. The currency has not physically disappeared and has not lost its nominal value in a legal sense. What is happening is a rounding effect that occurs when:

• a currency’s exchange rate falls below one millionth of a euro or a dollar;
• exchange services, banks, and rate aggregators do not display more than 5-6 decimal places;
• the currency ceases to be perceived as a store of value or a means of settlement outside its home country.

Under these conditions, even a non-zero value appears as “zero” to the user. Formally, the exchange rate exists, but in practical use it loses its meaning. This is not so much a mathematical collapse as a psychological and financial one.

Similar situations have occurred before in global economic history. Comparable effects were observed in Zimbabwe, Venezuela, and a number of other countries where the national currency continued to exist nominally but stopped performing the basic functions of money. The rial is now following the same trajectory: the population prefers foreign currencies, durable goods, or informal instruments for preserving value.

For Iran’s economy, this means further acceleration of inflation, growth of the shadow currency market, a decline in purchasing power, and increased social tension. For external observers, it is a clear illustration of how the combination of sanctions, political decisions, and a loss of trust can push a currency into a state where it exists only on paper.

Thus, the rial is not equal to zero in a strict mathematical sense, but in the eyes of markets and financial systems it is already almost indistinguishable from zero. And in economics, as is well known, perception often matters more than formal definitions.
