After decades of negotiation, many United Nations (UN) sanctions were eased in January 2016 after a milestone nuclear deal was reached in 2015, meaning the money could be released, Swissinfo reported.
A spokesperson for the State Secretariat for Economic affairs (Seco) confirmed on Sunday that the money had been unfrozen. It belonged to either individuals, companies or government-owned institutions.
The nuclear deal also opened up Iran to new international business opportunities, some Swiss firms are hoping it could lead to a fresh market outlet.
