Does striking the shadow fleet actually move Russian export volumes?

Movement observed

The US–Russia channel continued at the level of statements: the Kremlin said practical work had begun on Russian diesel supply after US sanctions relief, and OFAC renewed its Lukoil International sale licence to 21 November (General License 131K, a renewal). Russian claims of strikes on Odesa-region port infrastructure named no port. No crude-volume, discount or insurer figure was read at source.

The 16 October order set the act's tariffs on the largest buyers of Russian crude and gas and on evasion facilitators, and waived them with no expiry, so the buyer-side lever is not in play; designations under the earlier executive orders stand. Ukraine's agriculture ministry said about 32 million tonnes of exports are at risk at sea. No crude-volume, discount or insurer figure was read.

The instrument moved both ways: the US licensed Russian-origin diesel trade to April 2027, and the UK sanctioned 12 more tankers and 38 energy companies on 8 October. The tanker Rio burned off Sochi on 6 October after a reported sea-drone attack. No crude, discount or insurer figure read; no marker strike found.

A cargo ship struck on 3 October at an unnamed port near Odesa, one crew member killed. A 28 September decree restricts Russian export and customs data, leaving independent tracking as the only basis. A US plan for a Black Sea shipping halt was reported, not held. No crude, discount or insurer figure read this cycle; Krasnodar quiet.

The instrument changed and the volumes did not, which is this question's whole point. The act signed on 18 September provides for sanctions on the shadow fleet and tariff authority against the largest buyers of Russian oil and gas; no designation had been announced by the cutoff, so no insurer behaviour, realised discount or export-volume effect can yet be read from it. No independent seaborne-crude or grain figure was published in the window. Russia claimed strikes on two commercial vessels in the Black Sea on 19 September; no other party confirmed them and they are recorded as a claim, not as enforcement in either direction.

The corridor was struck again on the night of 8–9 September — Ukraine’s Defence Intelligence and Navy state the naval base at Novorossiysk and the frigate Admiral Essen were hit, with no Russian statement identified. The object’s question is about volumes, and nothing moved there: no change in Russian seaborne crude volumes or in the realised discount attributable to the campaign has been established on tracking independent of either belligerent, and the suspended grain terminals are unchanged.
