Following the signing of the US–Iran deal on June 18th, OFAC announced on Sunday that Iranian oil sales would be permitted until 21 August, aligned with the MoU timeline.
Iranian crude and condensate exports trended at roughly 1.7 Mbd prior to the war and fell to near zero in May and the first half of June following the US naval blockade imposed in mid-April. Since the blockade has been lifted, at least one Iranian crude-laden tanker has transited the Strait of Hormuz each day between 18 - 22 June.

Following the announced US–Iran Memorandum of Understanding (MoU), OFAC's General License now permits sales of Iranian-origin crude oil, petrochemical products, and petroleum products for a two-month window.
On the crude oil side, we expect the combination of blockade removal and sanctions relief to drive a steep recovery in Iranian production. Supply is estimated to have fallen by as much as 1.3 Mbd during the blockade, a consequence of the inability to export rather than damage to producing assets (condensate production at South Pars largely back by now). In this new environment, we could see a swift rebound in crude and condensate output: from 2.9 Mbd in June to 4.0 Mbd in July and 4.2 Mbd by August. Should waivers be extended beyond August, supply could be pushed closer to 4.4–4.5 Mbd, with Iranian crude exports rising from the pre-war levels of 1.7 Mbd to around 2.0 Mbd, considering historical records and available capacity.

Beyond ramping up production, Iran will prioritize drawing down oil inventories and maximizing exports — particularly within the window before the US implements new restrictions on August 21st. Even where buyers cannot be found immediately, Iran could move these cargoes out of the Gulf and store the oil offshore in Asia as a hedge against a renewed naval blockade choking off exports.
We do not expect a broad set of new buyers to emerge within this timeframe. Western buyers, both US and European ones, would face lengthy regulatory procedures covering compliance checks, credit lines, due diligence, and banking infrastructure, which would almost certainly not be completed within the 60-day window. When accounting for transit times from Iran of approximately 40–45 days alongside associated operational lead times, the full supply chain loop is unlikely to close before the waiver expires.
