It's not yet clear who will succeed Zanganeh when he steps down, most likely in mid-August. But whoever it is will take the reins at a sensitive time. If US-Iran talks in Vienna lead to sanctions relief, Tehran has made clear its intention to swiftly restore its crude output to pre-sanctions levels and hike exports, even if some voices within Opec-plus call for restraint (PIW May28'21). A senior Iranian oil source insists the choice of the country's next oil minister won't affect Iran’s position toward Opec-plus or its planned return to the market.
