Kofi Bentil, a leader at IMANI Africa, has publicly described the sale of 18 tonnes of Ghana's gold as an extreme action.
He believes this gold sale will cause Ghana to lose more than one billion dollars.
Bentil stated that no sensible government would allow an action that costs a poor country such a large sum of money.
He raised concerns about the decision-making process behind the gold disposal.
Bentil indicated that such a deal suggests something is not right.
Further details on the terms of the sale and the buyer have not been released.
The transaction involves a significant portion of the nation's gold reserves.
Ghana relies heavily on gold exports for its national income.
