Hormuz Ship Traffic Collapses as US-Iran Ceasefire Lapses, Trump Threatens Oman

5 min readPublished 24 Aug 2026

Commercial shipping through the Strait of Hormuz has all but stopped after a 60-day US-Iran ceasefire lapsed without a replacement agreement. CNN reported that at least three commercial ships passed through the strait over a 24-hour window, citing MarineTraffic data. CNBC separately reported that only three ships transited on Sunday, citing Kpler data — two independent trackers arriving at the same headline number.

The strait is, in Crypto Briefing‘s description, “a critical chokepoint for global oil shipments.” With the ceasefire lapsed and no replacement announced, a resumption of strikes on shipping is the risk analysts would watch for — an inference from the collapse in traffic, not a development any outlet reviewed here has reported as having occurred. The more immediate story is that outlets disagree sharply on how bad the disruption already is, and reconciling those measurements is what follows.

When exactly did the ceasefire expire?

Even the expiry date is contested. Crypto Briefing reported on the morning of August 17 that the 60-day ceasefire expired “today.” CNBC reported the truce, signed in mid-June, was set to expire Monday, August 19. CNN’s live coverage, published August 17 and updated into August 18, said the 60-day deadline for the two sides to reach a deal “has now passed.” The three accounts do not line up on a single date, and none of the outlets held in full for this review reconciles the discrepancy.

Where the outlets agree — and where they don’t

On the headline fact of collapsed traffic, CNN and CNBC align closely. CNN put transits at three ships in the past 24 hours, against a pre-war baseline it described as roughly 110 ships crossing daily. CNBC also reported three ships crossing, but on Sunday specifically, against a five-day average of 12 transits and a pre-war daily baseline it put at around 130 vessels. The two outlets’ pre-war baselines differ by roughly 20 vessels a day, and neither report in this evidence set explains why.

Crypto Briefing’s numbers tell a different-sized story. Citing MarineTraffic, it reported vessel traffic through the strait fell 19.5% over the prior week — a figure its own headline rounded to 20%. A 19.5% weekly decline describes meaningful disruption, but it is a fraction of the near-total stoppage implied by CNN and CNBC’s raw ship counts. None of the three outlets cross-references the others’ figures, and this evidence pack does not contain an explanation for the gap — whether it reflects different measurement windows, different definitions of “traffic,” or something else. Readers should treat the two pictures as distinct until that is resolved.

All three outlets agree the strait has not been fully closed. CNN noted some vessels are still moving — two tankers into the Persian Gulf and one vessel out into the Gulf of Oman in its 24-hour window. Crypto Briefing likewise said the strait “has not been completely closed,” with some ships still making the passage.

Trump’s threat to Oman and a disputed backchannel claim

CNN alone reported that President Trump warned he would attack Oman if the country “gets in the way” of US efforts in the strait — a warning CNN noted echoes a threat Trump made against the same US ally in May. CNN also reported Trump said he is in no rush to reach a deal and claimed his administration has opened a direct backchannel with Iran’s Islamic Revolutionary Guard Corps, a claim the IRGC denies. Neither the Oman threat nor the IRGC backchannel claim appears in the other outlets reviewed here.

CNN also reported that Trump pushed back on reporting — including CNN’s own — about dwindling supplies and low morale aboard the USS Abraham Lincoln, which CNN said has been deployed more than 250 days after being redirected to the Middle East for the war. Trump called the reporting “fake news,” according to CNN.

The CENTCOM tally and wider Gulf traffic

CNN cited a US Defense Department statement on enforcement activity in the strait:

“CENTCOM forces have redirected 64 commercial vessels, disabled 3, and boarded 2 to ensure compliance,”

as of August 17, according to the statement CNN cited. CNN also reported that traffic through a second Middle East chokepoint, the Bab al-Mandeb strait, remained muted, with at least 37 commercial ships transiting over the same period — 19 vessels entering the Red Sea (13 cargo ships and six tankers) and 18 leaving into the Gulf of Aden (13 cargo ships and five tankers). CNN further reported that GPS spoofing continues to complicate monitoring, throwing off some vessels’ broadcast positions by dozens of miles.

Separately, CNN reported that Masrour Barzani, prime minister of Iraq’s Kurdistan Regional Government, blamed Iran for drone strikes aimed at his own office and at the home of Parastin’s intelligence chief. Tehran rejected the claim and floated the possibility, per CNN, that the strikes were a “false flag” operation.

Prediction-market pricing: single-sourced and unconfirmed elsewhere

Crypto Briefing, drawing on pricing it attributes to prediction markets tracked through a service called Vera, reported that the probability of a US-Iran agreement by August 31 fell to 10.5% YES. In a separate report, Crypto Briefing said the probability of Hormuz traffic returning to normal by September 30 fell to 11.5%, down from 16% a week earlier. No other outlet in this review cites these figures or the underlying market. They should be read as one outlet’s characterization of market sentiment, not as independently verified data.

Context: the deal that fell apart

Al Jazeera — held here as context only, not a corroborating newsroom — reported that the memorandum of understanding included a US commitment to a reconstruction and development package for Iran, sanctions relief, and a US pledge to withdraw its forces from near Iran only after a “final deal” was reached. Al Jazeera also reported that disputes over which shipping routes through the strait Iran would recognize as safe contributed to the breakdown. Because this account comes from a source held only for lead-generation in this review, none of its specifics should be treated as confirmed until a corroborating newsroom reports them.

What remains unresolved

Several questions sit open across this evidence. It is unclear which pre-war baseline — CNN’s roughly 110 daily transits or CNBC’s roughly 130 — is more accurate, and why MarineTraffic and Kpler, the two data providers cited, produce different pictures of a period before the current collapse. It is similarly unclear why Crypto Briefing’s 19.5% weekly decline sits so far from the near-total stoppage CNN and CNBC describe in raw ship counts; a measurement-window or methodology difference is the likely explanation but is not spelled out in any of the reporting reviewed. Whether Washington and Tehran resume formal talks, whether Trump acts on his threat toward Oman, and how reliable the single-outlet prediction-market figures are as forward indicators all remain open.

What to watch next

Crypto Briefing’s reporting points to two dates worth tracking: August 31, tied to the market it cites on a broader US-Iran agreement, and September 30, tied to the market it cites on Hormuz traffic normalizing. Beyond that, statements from Trump, Iranian officials, or Omani mediators on resumed negotiations or a revised ceasefire framework would mark the next concrete development, as would any follow-through on the Oman threat CNN reported, or further CENTCOM disclosures on vessel activity in the strait.
