Vortexa put Iran's May crude and condensate exports at 209kbd, down 84% from April, with 67 million barrels stranded in the Gulf and reserves perhaps two months from exhaustion.

Key takeaway

Iran's 209kbd export floor takes a structural seller off the water with no quick restart available.

Vortexa, the tanker-tracking analytics firm, put Iran's May crude and condensate exports at 209kbd (thousand barrels per day), down 84% from April's 1.34mbd⁠1. Some 67 million barrels of Iranian crude now sit stranded in the Gulf, unable to clear the Strait of Hormuz blockade, with onshore reserve capacity roughly two months from exhaustion at the current rate.

The number matters less as a monthly print than as a structural break in supply. An export figure this low, sustained, removes Iran from the medium sour pool that Mediterranean and Asian refiners draw on, rather than dipping it for a quarter. Once the 67mb of floating storage clears or strands permanently, there is no quick restart: a blockaded producer cannot ramp the way an OPEC member with spare capacity can.

Iran's 209kbd floor extends the supply destruction that narrowed the East-West crude arbitrage last week as Chinese seaborne demand also fell to a decade low. With Iranian Light flipping to a discount against Brent, the compression reads as a China-side demand hole rather than fresh Iranian length. Both forces point the same way: less physical crude reaching the water, against a quota schedule that assumes barrels are waiting to be switched on.

Deep Analysis

In plain English

Before the current conflict, Iran exported around 1.3 million barrels of oil per day. In May, that figure collapsed to just 209,000 barrels per day because of a blockade of the strait of Hormuz, the narrow waterway through which most Gulf oil must pass. On top of that, 67 million barrels of Iranian oil are now sitting on tankers in the Gulf with nowhere to go. That is roughly twice the amount of oil the UK uses in a month. If export channels do not reopen, Iran will start running out of storage space and be forced to cut production itself, which could push global oil prices higher still.

Deep Analysis
Root Causes

The 209kbd export figure reflects two overlapping constraints. The first is the CENTCOM port blockade redirecting over 108 vessels by 27 May; no VLCC can load at Kharg Island or Bandar Imam Khomeini without risking interception.

The second is an accelerating insurance gap: OFAC's sequential hull-by-hull tanker designations, 22 vessels and entities named in the 28 May action alone, have compressed the pool of P&I-covered tonnage willing to handle Iranian crude to a narrow set of vessels operating under non-Western reinsurance (principally the Iran P&I Club and RNRC), whose total hull-loss capacity is limited.

The Brent-Dubai EFS, which widened above $6/bbl through 4-8 May and has since directionally compressed, reflects both constraints: the light-sweet Hormuz bid deflates when blockade news eases, but the hard floor on the spread persists as long as the insurance gap limits physical delivery of sour Gulf crude into the Platts Dubai assessment window.

What could happen next?
  • Risk

    Iran's 67 million barrel Gulf stockpile exhausts in approximately two months at current rates, forcing a production cut rather than an export disruption, a structurally more severe supply loss that takes longer to reverse.

  • Consequence

    The Brent-Dubai EFS compression from the $6+ May peak reflects the market partially pricing in a post-blockade rebalancing; a failure of the export channel to reopen by August would push the EFS back towards May highs.

The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.

Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.

The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.

Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
