FX Rate Archive Since 2008
The price of every currency on every day — from the dollar at 940 toman in 2008 to today.
Where does this data come from?
This archive is the same rate database the Nexto exchange software runs on: Toman rates recorded daily since 2008 and the other currencies since 2016. Each currency's rate in Toman is calculated by cross-rating against the dollar rate of that same day.
The source, the exact meaning of each number, the time zone, the cross-rate formula and the policy for days with no data are set out on a separate page. Methodology and citation
