What happened

Key facts

  • Iran’s floating oil reserves, used for sales to China, were reported as completely depleted, with analysts cited in the headline and InvestingLive describing the stockpile as exhausted (per investinglive.com, The Jerusalem Post).
  • Before the United States imposed a blockade on Iranian ports in April, Iran held close to 150 million barrels of oil in floating storage (per oilprice.com, iranintl.com).
  • Iran’s floating oil storage had fallen below 50 million barrels by mid-June, when the United States lifted its blockade following a ceasefire deal between Washington and Tehran (per oilprice.com, iranintl.com).
  • The ceasefire deal between Washington and Tehran collapsed in mid-July, hostilities resumed, and the United States reimposed its blockade (per oilprice.com, iranintl.com, investinglive.com).
  • InvestingLive reported that Iran’s floating oil reserves had fallen below 1 million barrels by October 5 and had since been exhausted, according to analysts (per investinglive.com, oilprice.com, iranintl.com).
  • InvestingLive reported that Iran had around 135 million barrels stored overseas when the war began in February, with an estimated value of $10 billion or more after oil prices rose (per investinglive.com).

The brief

Iran’s oil held in floating storage had shrunk to 866,000 barrels by mid-October, according to Kpler data cited by the Wall Street Journal and reported by OilPrice.com. InvestingLive said analysts considered the stockpile exhausted. The two descriptions differ in precision: one gives a remaining volume, while the other characterizes the reserves as depleted.

The Jerusalem Post headline likewise described the reserves used for China sales as completely depleted. The decline followed changes in the U.S. blockade of Iranian ports. OilPrice.com reported that Iran had close to 150 million barrels in floating storage before the United States imposed the blockade in April.

The volume was below 50 million barrels by mid-June, when Washington lifted the blockade after a ceasefire deal with Tehran. The deal collapsed in mid-July, hostilities resumed, and the United States reimposed the blockade.

InvestingLive supplied a separate threshold in the drawdown: Iran’s reserves had fallen below 1 million barrels by October 5 and, according to analysts, were subsequently exhausted. It also cited another tracker estimating about 6 million barrels off Singapore as of October 9.

That estimate does not match the reported mid-October figure of 866,000 barrels, but the sources do not identify the trackers’ different coverage or measurement basis, so the figures cannot be treated as measurements of the same stock at the same point. The reporting links the depleted inventory to Iran’s oil sales to China.

The Jerusalem Post headline described the floating reserves as being used for those sales; InvestingLive said their depletion cut off sales to China. OilPrice.com reported the Kpler estimate and the blockade sequence, but did not state that China purchases had stopped.

The coverage therefore presents the effect on sales in more categorical terms in InvestingLive and the Jerusalem Post headline than in OilPrice.com. U.S. Central Command said the blockade had denied Iran at least $25 billion in oil revenue and would constrain Tehran’s ability to replace destroyed factories and weapons.

InvestingLive reported that claim, and Iran International also carried the command’s statement. The revenue figure and forecast are the U.S. military’s claims; the sources do not supply an independent calculation of the loss or detail the expected effect on replacement capacity.

InvestingLive said Iran had around 135 million barrels stored overseas when the war began in February, potentially worth $10 billion or more after oil prices surged. OilPrice.com gives a different starting estimate for floating storage—close to 150 million barrels before the April blockade.

The sources do not clarify whether the difference reflects distinct dates, definitions, or estimates, so the two figures should not be combined. The immediate economic focus is the dwindling volume available in floating storage and the U.S. military’s stated estimate of lost revenue.

The reporting does not establish how much oil Iran has in other forms of storage or quantify the resulting change in China’s purchases.

Why it matters

  • Iran’s government faces a reported loss of at least $25 billion in oil revenue, according to U.S. Central Command; the command said that could constrain replacement of destroyed factories and weapons.
  • The reported supply buffer fell from close to 150 million barrels before the April blockade to 866,000 barrels by mid-October, leaving far less oil in floating storage.
  • China’s oil purchases are directly implicated: InvestingLive said depletion cut off sales, while the Jerusalem Post headline described the reserves as used for China sales.

What to watch next

  • Whether U.S. Central Command reports further figures for oil revenue denied by the blockade.
  • Whether subsequent reporting provides a new estimate of Iranian oil in floating storage after the mid-October figure of 866,000 barrels.
  • Whether the reported cutoff in sales to China is reflected in a stated change in purchases.

How outlets' accounts compare

1 factual disagreement · 5 framing differences · 3 uncorroborated claims · 2 information gaps
Sources disagree on one factual point.Compared across 3 reports whose article text Updat3 read; 2 other outlets were checked by headline only.
Factual disagreements
Sources report different numbers, dates, attribution or causes for the same thing.
  • InvestingLive reports both a tracker estimate of about 6 million barrels off Singapore as of October 9 and an exhaustion assessment after reserves fell below 1 million barrels by October 5. The sources do not explain the scope or measurement differences behind these figures.
Updat3: The evidence conflicts; Updat3 does not present either version as established.
Framing / emphasis differences
Sources emphasise different angles, actors or consequences of the same reporting.
  • InvestingLive and the Jerusalem Post headline describe the floating reserves as exhausted or completely depleted; OilPrice.com gives a Kpler figure of 866,000 barrels for mid-October.
  • InvestingLive says depletion cut off sales to China, while the Jerusalem Post headline says the reserves were used for China sales; OilPrice.com reports the storage drawdown without stating that Chinese sales stopped.
  • OilPrice.com emphasizes the blockade timeline and Kpler’s storage data; InvestingLive foregrounds the claimed impact on China sales and U.S. Central Command’s revenue-loss figure.
  • OilPrice.com reports close to 150 million barrels before the April blockade; InvestingLive reports around 135 million barrels stored overseas when the war began in February. The dates and storage descriptions differ, so these are not necessarily competing measurements of the same quantity.
  • The reported starting stock estimates differ: OilPrice.com gives close to 150 million barrels before the April blockade, while InvestingLive says around 135 million barrels were stored overseas when the war began in February. The sources do not reconcile the dates or definitions.
Updat3: These are differences of emphasis, not disputes about what is reported. They do not show that the reported claims are true.
One-sided or uncorroborated claims
Claims that come from one party or one source family and are not independently corroborated.
  • U.S. Central Command attributes at least $25 billion in lost oil revenue and constraints on replacing factories and weapons to the blockade; these are the command’s claims.
  • U.S. Central Command said the blockade had denied Iran at least $25 billion in oil revenue.
  • InvestingLive reported that depletion of the floating stockpile cut off sales to China.
Updat3: Not independently corroborated yet — treat as a claim, not an established fact.
Not established by the reporting
Information the available reporting does not contain or confirm. This is a gap, not a disagreement.
  • The sources do not describe the amount of Iranian oil in onshore or other non-floating storage.
  • The sources do not provide an independently verified calculation of the oil revenue lost or detailed evidence for the expected constraint on replacing factories and weapons.
Updat3: Updat3 cannot conclude anything about this from the current sources.

How we got here

The United States imposed a blockade on Iranian ports in April 2026, after the war that began with coordinated U.S.-Israeli strikes on Iran on February 28. By mid-June, Washington and Tehran had reached a ceasefire deal and the United States lifted the blockade. The deal collapsed in mid-July, hostilities resumed, and the United States reimposed the blockade.

Before the April blockade, Iran had held close to 150 million barrels of oil in floating storage, according to reporting by OilPrice and Iran International. Iran’s reliance on oil sales, including shipments to China, developed within a sanctions system aimed at curbing its nuclear program.
