Sure, at current internal exchange rates, however, it is highly unlikely that the IMF, EMF, World Bank etc will allow $600Bn to become IQD700Tn and then (for easy math without any lopping) at a 1:1 RV becomes $700Tn ... so I’d only expect a transfer of these frozen funds back to Iraq after normality has been restored, including whatever happens to the IQD exchange rate, to maintain parity in purchasing power of those funds.
The $600Bn, if transferred to the CBI, I assume would most likely be used to support the national reserves, which will be a good thing any way you look at it.
Just my own, humble, opinion ...
