Given that the US is pushing foreign banks to stop dealing with Iran why would Iran want to hold or take US currency?
So far the sanctions that Euro banks have supported (and I think ANZ also) have been to ban dealings with Iran in US $ but to continue with Euro and other currencies.
Will be interesting to see how this all plays out. US main concern will be whether the practice spreads but the more the US$ falls the more other central banks will change their holding policies.
