Supply Chain Stability as Strait of Hormuz Set to Reopen?

A framework agreement between the US, Israel and Iran could restore access to the Strait of Hormuz within weeks. The deal was announced on Sunday 14 June by Pakistani Prime Minister Shehbaz Sharif, who confirmed Washington and Tehran had agreed to end hostilities on all fronts.

The memorandum of understanding offers logistics managers a timeline for planning around one of the world's most critical shipping chokepoints. According to Iranian state media, roughly 20% of global crude supply transits through the strait.

The closure forced a rerouting of shipping schedules across multiple continents and created immediate disruption to energy logistics networks.

Mine clearance and phased access

The reopening presents operational challenges that will constrain freight capacity for weeks. Iranian forces will clear the strait of sea mines for the first 30 days. No tolls will be charged to vessels during the 60-day period.

Mark Montgomery, a retired US Navy Rear Admiral, said on BBC Radio 4's Today programme that mine clearance in the strait could take "weeks to months". He added that full unrestricted transit without naval escorts conducting constant route clearances would take considerably longer.

Mark said there could be some "obvious relief" within a week. Supply chain managers should expect gradual phase-ins rather than overnight normalisation of shipping schedules.

The phased reopening means initial transit capacity through Hormuz will likely be constrained to escorted convoys rather than free navigation. This will require shippers to coordinate departure windows with naval authorities, potentially adding 24 to 48 hours to voyage planning compared to pre-conflict operations.

Extended voyage times and rerouting costs

During the closure, shipping lines implemented emergency rerouting protocols that extended voyage times and increased operational costs. The primary alternative route around the Cape of Good Hope added approximately 3,500 nautical miles to the standard Asia-Europe shipping lane, translating to an additional two weeks of transit time for container vessels.

This diversion created cascading effects throughout global supply chains. European manufacturers dependent on components from Asian suppliers faced inventory shortages as lead times extended from the typical 30 to 35 days to 45 to 50 days. Automotive plants in Germany reported production slowdowns due to delayed shipments of electronic components and specialised parts normally routed through the Persian Gulf.

The Suez Canal route remained unavailable for vessels originating from or destined for Persian Gulf ports. Some shipping companies experimented with land-bridge solutions, utilising rail freight through Central Asia and Turkey, but these routes offered limited capacity and were economically viable only for high-value, time-sensitive cargo.

Bunker fuel costs will benefit from lower crude oil prices. The price of Brent crude fell more than 4% to around US$83.60, while West Texas Intermediate approached US$80 a barrel for the first time since early March.

According to Tamas Varga, an analyst at PVM Oil Associates, the two major crude benchmarks had already lost almost US$6 per barrel over the previous week, with a further US$4 shed overnight.

"The pre-crisis status quo may never be fully restored, or at least not for a long time, but the most pressing issue, the resumption of oil and other commodity flows, appears likely to be resolved in the foreseeable future," he said.

Container shipping volumes through the Persian Gulf region are expected to recover gradually. Maersk and MSC, two of the world's largest container lines, have indicated that full service restoration to pre-conflict schedules will require six to eight weeks following the initial reopening.

Despite global reservations, the UK’s Prime Minister, Sir Keir Starmer, described the deal as a "hugely significant moment", saying it was "vital that all parties seize this opportunity to secure stability in the region and restore freedom of navigation in the Strait of Hormuz".

Ursula von der Leyen, the President of the European Commission, echoed these sentiments, saying that the agreement opened "the door to broader negotiations on peace and security in the Middle East", while she also called for the "immediate reopening" of the strait.

Recovery timelines

"The re-opening of the Strait of Hormuz eases supply chain pressure but doesn't cure it," explains Tammy Kulesa, senior director, supply chain execution, Blue Yonder.

"The Strait of Hormuz re-opening restores vital oil and goods flows and eases supply chain shortages, but backlogs, high freight costs and refinery disruptions mean a return to normal operations will be slow and uneven. Shippers, manufacturers and consumers can expect some relief, but our expectation should be that it is gradual and irregular. Companies need to treat this as a window, not a resolution.

"Companies will prioritise the movement of critical shipments and need to actively manage transportation risks by diversifying routing and modal options to preserve service commitments. Scenario planning, real-time monitoring and readiness for renewed disruption are essential for maintaining operational stability amid volatile global conditions."

Logistics planners will need to monitor multiple variables over the coming weeks. These include mine clearance progress, naval escort availability, insurance premium adjustments and geopolitical developments in Lebanon.

The 60-day negotiation window provides a timeframe for operational planning, but supply chain resilience will depend on whether the framework translates into sustained stability for maritime freight routes through the Persian Gulf.
