USD to IRR Exchange Rate History — Iran
This page charts the historical USD to Iranian Rial (IRR) parallel — or "black market" — exchange rate in Iran. As new readings are collected they appear in the chart and tables below, building a record of how the street price of the dollar has moved over time.
Sanctions and inflation have made Tehran's free-market ("bazaar") dollar rate the number Iranians actually price goods in — quoted in both rials and tomans.
How to read the IRR rate history
The chart plots the parallel buy rate — how many IRR it took to buy one US dollar — at each point we recorded. The daily table below lists the closing buy and sell rate for each day, while the monthly table summarises the average, high and low for each month, which is useful for comparing one period with another.
A rising line means the Iranian Rial is losing value (more IRR per dollar); a falling line means it is gaining.
What has moved the Iranian Rial recently?
In Iran, the parallel rate is driven by factors such as international sanctions, high inflation, restricted access to hard currency. When dollars become scarcer or confidence falls, the street rate climbs ahead of the official Central Bank of Iran (CBI) rate; when supply improves or policy tightens, the gap can narrow again.
Because the parallel rate often moves before official devaluations, its history is a useful early-warning record — a steadily rising trend frequently precedes an official adjustment, while a long plateau suggests relative stability.
Using historical IRR rates
Historical rates help with budgeting, invoicing, remittance planning and spotting trends, but they are not a forecast — past movements do not guarantee future ones. For the live rate, see our main USD to IRR page, and use the converter for exact amounts.
