Article: “SUDANESE ADVISOR: THE OFFICIAL AND PARALLEL EXCHANGE RATES MATCH DEPENDS ON THIS MATTER” I believe this is part of the process to the RV and reinstatement.

The official rate and parallel market rates must match with only a small variance allowed and I quote – “If the difference between them is 2%, then it is considered a match.”
