Problem being, in Argentina are two FX's in regards to restrictions of the Government.
1) The official rate around 9.17 ARS / USD (unreachable for outside Argentina accounts)
2) The blue rate around 14.50 ARS / USD (offshore fx, i.e. everyone outside Argentina)
Hence the client statement is overstating the position.
the following calculations based on indicative pricing:
