Standing assessment
Current condition
Moderate confidenceAs of
Ukraine publishes vessel names and running totals of tanker strikes; Russia minimises or denies them; nobody independent counts.
No further strike on Novorossiysk or Ust-Luga has been identified since 14 August, the suspended grain terminals are unchanged, and no movement in Russian seaborne crude volumes or the realised discount attributable to the campaign has been established on tracking independent of either belligerent. The capitals-only strike pause of 5 September does not extend to the corridor.

Why it matters
Ukraine describes the campaign as enforcing an economic regime its partners write but police through paperwork. A campaign can be real, sustained and widely filmed and still not show up in the export data — and the mechanism by which it works, if it works at all, is shipowners and insurers changing behaviour. That is why the observable is deliberately not the tally: the strikes are the input, the export series and the insurance market are the output, and the question is whether the second follows the first.
Observables5 named · “met” describes evidence, not success
01Test
Russian seaborne crude volumes on independent tracking
Monthly volumes from export-tracking sources that depend on neither belligerent, read against the pre-campaign months.
02Test
The realised discount on Russian crude
Whether the discount widens in the direction the strikes are meant to push it, on the same independent tracking.
03Test
War-risk insurance premiums and shipowner behaviour
Premium movements, cover withdrawals or shipowners declining Russian cargoes — the mechanism by which the strikes work, if they work.
04Test
Strikes on port and grain-handling infrastructure
Whether the campaign's object widens from tankers to terminals on either coast, which changes what the export series measures.
05Test
Monthly Ukrainian export volumes against pre-war baselines
The corridor's own output, read separately from the Russian side so the two are never netted against each other.
What would change the assessment2 thresholds · the boundaries as the record states them, none with a number
Two consecutive months of independent tracking showing Russian volumes or the discount moving in the direction the strikes push, with insurers changing terms in the same window.
Sustained strikes with no movement in the export data across a quarter
Would meanshows the campaign to be real and ineffective as an economic instrument.
What remains unknown
- No independent count of tanker strikes exists; the running totals are Ukrainian and the denials Russian.
- The share of Russian exports carried by sanctioned tankers, against which any effect has to be read, is estimated by different trackers on different bases.
Readings the evidence also supports
- Export volumes move on sanctions enforcement, price caps and buyer behaviour in India and China rather than on strikes, in which case the series answers a different question.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
