Western Bulk, a dry bulk operator, reported in its own public updates that three vessels were held up in the Persian Gulf while the Strait of Hormuz was closed, and later that all three had exited safely. The same updates name four areas of the business the episode touched: the vessels, fuel bought at a premium to its hedges, cargo commitments and tonnage commitments. This page sets out what the company said, where it said it, and what a person reviewing each area would still need to know.
A summary of the company-confirmed claims below, from Western Bulk's updates of 10 April 2026 and 30 June 2026. Each claim opens to its source.

Daily transit calls, Strait of Hormuz, as collected by Vaethra (source portwatch-chokepoints)
Latest day included

Read
26 September 2026, 15:05 UTC
Evidence class
Direct observation: A figure Vaethra collected from a public feed, with that feed's own date.
Method
Monthly mean of daily values in terminal.observations (entitychokepoint:strait-of-hormuz, metric transits, source portwatch-chokepoints); the baseline is the median of the 365 daily values in 2025. Read 2026-09-26 15:05 UTC.
Timing
PortWatch publishes weekly. Strait transits reach Vaethra up to ten days after the day they describe, and PortWatch revises recent days.
Caveat
Counts all vessel types PortWatch detects. It says nothing about Western Bulk's vessels, and it is context for the same months, not evidence of the company's account.
Use
IMF PortWatch open data; attribution required.
Four review areas
The company's own updates name four parts of the business the episode touched. Each is a place a person
would look, not a finding: what Western Bulk said is marked company-confirmed; what would still need to be
checked is marked as a working hypothesis, with what would disprove it.

What a reviewer would still need to know
Which voyages were due through the strait, how long each vessel waited, and what the wait did to its next fixture.
Working hypothesis Each held vessel's wait moved the dates of the fixture that followed it.
Would be disproved by: Voyage records showing the following fixtures kept their original dates.
Missing: Vessel names, voyage schedules and fixture terms are not public.
Review 02
Fuel and its hedge
Joined to the event by: Company-confirmed the company named it in Dividend and Market Update – First Quarter 2026
What the company said
On 10 April 2026 Western Bulk said fuel costs had risen because physical bunkers cost more than the financial swaps used against them.Company-confirmedWestern Bulk, 10 Apr 2026Evidence

What a reviewer would still need to know
Which fuel purchases paid the physical premium, and how far the swaps covering them fell short.
Working hypothesis The premium fell mainly on fuel bought for voyages connected to the Gulf, not across the whole fleet.
Would be disproved by: Company data showing the same premium on fuel bought for voyages with no connection to the Gulf.
Missing: Bunkering ports, volumes, prices and hedge positions are not public.
Review 03
Cargo commitments
Joined to the event by: Company-confirmed the company named it in Dividend and Market Update – First Quarter 2026

What a reviewer would still need to know
Which cargo contracts loaded or discharged in the Persian Gulf, and how each was performed, replaced or settled.
Working hypothesis Cargo commitments with a Gulf load or discharge port were performed late or covered another way.
Would be disproved by: Contract records showing those cargoes were performed on their original dates or released without cost.
Missing: Cargo contracts, counterparties and terms are not public.
Review 04
Tonnage commitments
Joined to the event by: Company-confirmed the company named it in Dividend and Market Update – First Quarter 2026

What a reviewer would still need to know
Which chartered-in vessels were committed to Gulf trades, and whether they were relet, idle or repositioned.
Working hypothesis Tonnage committed to Gulf trades was repositioned or earned less while the strait was closed.
Would be disproved by: Records showing that tonnage was relet elsewhere at its original rate.
Missing: Charter parties and hire rates are not public.
What this page does not say
Western Bulk is not a Vaethra customer or user, and did not supply any of this.
No vessel name, position, cargo, counterparty, price or hedge position is shown, and Vaethra holds none.
Nothing here estimates a loss or predicts what happens next.
The four review areas are what the company's own words name. They are not edges in Vaethra's graph and not a measure of exposure.
Public context, recorded separately
The strait, in Vaethra's own record
Western Bulk is not an event in the Terminal and has no edges in Vaethra's graph. These open
the public record for the Strait of Hormuz, which is a different thing from the company's account above.
Direct observation a separate record from the company's
Terminal
Vaethra's own public record for the strait: its observations and the events attributed to it. Western Bulk does not appear there.
Scenario path a separate record from the company's
Atropos
A separate scenario: the strait set to halted, traced two steps through Vaethra's recorded dependencies. It is not a forecast, and it does not contain Western Bulk or the four review areas above.
