How do Ukrainian strikes on Russian refineries change the oil arithmetic?

The Russian leg looks like a burst of front-loading rather than either a durable relocation of supply risk or the degradation this position originally argued. Neither the original reading nor its replacement is currently supported by the loading data.

What we observe
The loading surge did not persist
Russian Baltic departures read zero on each of the last three settled sessions to 1 September, after eleven on 29 August; the 30-day average has fallen to roughly 3.9 from roughly 7.7 on 23 August. Kozmino cleared one departure on 1 September against a seven-day average of about 1.6

The desk’s reading
Changed from revision 2, 27 August 2026
The Russian leg is a relocation of supply risk rather than a loss of supply. That is a different exposure with the same conclusion about a clean recovery.

The original argument was that Ukrainian strikes on Russian refineries opened a second seaborne supply story running in parallel with the Gulf, so that any Hormuz reopening would be absorbed against another loss rather than into a clean recovery.

Read the rest

The loading data went the other way in late August. The engine's tanker layer classified both the Russian Baltic and Kozmino readings as oil-surge signals with high confidence, with Kozmino having read sharply negative as recently as 21 August — a full reversal in five sessions. That was marked against the original degradation reading at the time.

It has since gone quiet, and that is marked here too. 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. So the front-loading burst did not become a relocation. The honest reading is that late August was a burst rather than a trend.

A caution about the series itself: it batches. Eleven departures cleared on 29 August, between runs of zeros. That makes the 30-day average the reliable measure and any single day close to meaningless, and it is why this position leans on the average having halved rather than on the three dark sessions.

So the conclusion is weaker than either previous version. A Hormuz reopening may still not deliver a clean recovery, but neither the Russian-loss mechanism nor the relocation mechanism is currently carried by the data, and the position should be read as open rather than as resolved in either direction.

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.

What would change this

Baltic and Kozmino loadings resuming above their 30-day averages for a sustained run — that would restore the relocation reading. A continued run of dark sessions with Brent holding above $90 would say neither relocation nor degradation is driving the barrel, and that the Gulf is.
