20M Barrels/Day Hormuz Oil Resumes Slowly; Logistics Disruptions Linger

For logistics and procurement professionals, the Strait of Hormuz reopening is not a switch that instantly restores the 20 million barrels per day of crude and products that transited before the war. Shipowners and insurers will only return cautiously—mine‐sweeping vessels are still at work, war‐risk premiums remain elevated, and the key bunkering hub of Fujairah is bracing for queues. Meanwhile, many importers that switched to alternative suppliers in the Americas and Africa may be in no rush to reroute back, creating a fractured, unpredictable recovery that will test supply chain resilience well into the fall.

A much-anticipated interim agreement between the United States and Iran, announced on June 15, 2026, has sent oil markets into a brief relief rally as it paves the way for the reopening of the Strait of Hormuz — the world’s most critical oil chokepoint. Yet, within hours, analysts from multiple trading desks and research firms sought to temper the euphoria, cautioning that the journey back to pre-conflict trade volumes would be measured in months, not days. The central message was unambiguous: while the headline may read ‘Hormuz reopens,’ the operational and psychological hurdles to a full restoration of 20 million barrels per day of oil transit are anything but instantaneous.

According to Haris Khurshid, chief investment officer at Karobaar Capital LP, “reopening is not a switch you flip, but a process,” noting that many buyers might not immediately return.

The Strait of Hormuz handles roughly one-fifth of global petroleum liquids trade, a volume that underpins energy security for dozens of nations. The conflict that preceded the interim deal forced tankers to take costly and lengthy detours around the Arabian Peninsula or the Cape of Good Hope, leading to a scramble for alternative supplies from the Americas, West Africa, and the North Sea. Those adaptations became deeply embedded in supply chains over months. According to Haris Khurshid, chief investment officer at Karobaar Capital LP, “reopening is not a switch you flip, but a process,” noting that many buyers might not immediately return. This sentiment was echoed across the analyst community: Priyanka Sachdeva of Phillip Nova highlighted that “the damage already done cannot be reversed overnight,” while Charu Chanana of Saxo Markets warned of a “messier” operational reality characterized by mine-clearing operations, elevated insurance premiums, port congestion, and the ever-present risk of geopolitical spoilers.

The insurance industry—instrumental for any tanker movement—remains deeply cautious. War-risk premiums that skyrocketed during the conflict will not vanish simply because an interim accord was signed. Underwriters are likely to demand steep additional premiums, and some may impose outright exclusions until there is sustained evidence of safe passage. Shipowners, scarred by previous attacks on vessels in the region, will also be reluctant to commit their fleets without robust guarantees. This hesitancy compounds the physical barriers: the strait and its approaches must be thoroughly swept for mines, a process that could take weeks even with multinational naval coordination. The result is a phased, bumpy ramp-up rather than a linear resumption.
