What happens to oil if the Strait of Hormuz reopens?
A reopening no longer implies a toll. Whether it implies a relocation of supply risk to routes nobody prices is now genuinely uncertain, because the Russian loading signal this position leaned on has not persisted.
This position argued a Gulf reopening would be absorbed against a parallel Russian supply loss, and that what lay on the other side of it was a toll rather than free passage. Both legs are now marked, and they are marked in opposite directions.

The toll leg has reversed, and in this position's favour. A transit fee requires the power to refuse passage, and the strait is not refusing it: 334 departures on 1 September against a 30-day average of 321, on the session US forces struck Iranian targets around it. Brent's premium over WTI narrowed to $4.43 on the same session. The settlement available to Tehran is passage without rent.
The Russian leg has gone against us, and it is worth being blunt about that. This position leaned on the engine's tanker layer flagging loadings out of the Russian Baltic sharply above their run-rate, with high confidence, as evidence that supply risk was relocating. That signal has not persisted: Baltic departures have read zero on each of the last three settled sessions, and the 30-day average has fallen to roughly 3.9 from roughly 7.7 on 23 August. A relocation of supply risk requires the destination route to keep loading, and it has not.
These are engine-derived loading signals rather than confirmed cargo manifests, and the series is lumpy — it batches, so a run of zeros can precede a large single day, as 29 August's eleven departures showed. That is a reason to hold the conclusion loosely, not a reason to keep asserting the original one.
So the headline conclusion survives on the toll leg and is weaker on the relocation leg. A reopening is still unlikely to deliver a clean recovery, but the confident version of why — that Russian supply picks up the slack and lengthens voyages — is not currently supported by the loading data.
Methodology note: this position previously cited market-implied probability bands. Antevo retired that layer from published research on 1 September 2026; the readings below are rebuilt on observable series — settled prices, the Brent-WTI spread and the engine's own daily tanker-departure counts. The view is unchanged by the substitution; where the evidence is now thinner, that is said.
Brent falling toward $80 on a confirmed corridor with the Russian loading signals staying dark — that would say a reopening does deliver a clean recovery after all. Brent is at $94.65 and moving the wrong way for that, but the Russian half of the condition is now partly met.
