There is going to be some confusion because there is not enough information along with the question. The temperature changes in the area, the depth of the basement in the ground, the relative humidity in the air - inside vs outside. Appliances in the room that might produce moisture and their venting. The material of the basement wall. All play a part in the answer.
Cold regions produce moisture collection on the block during cold weather. Humid climates produce moisture collection in the insulation and finish wall. A previous reference site suggests putting vapor barrier on both sides of the fiberglass insulation to stop absorption. - but that then leaves moisture between the block and the vapor barrier.
