Ukraine struck an oil tanker belonging to Russia’s so-called shadow fleet in the Black Sea on Wednesday, according to an official in the Security Service of Ukraine (SBU).

Russian state oil and gas revenue is likely to almost halve in December compared with a year ago to 410 billion roubles ($5.17 billion) as a result of lower crude prices and a stronger rouble, Reuters calculations showed on Friday.

At least three oil tankers have been hit by explosions in what appears to be a stepped up unilateral effort by Ukraine to sink Russia's sanctions-dodging oil sales.

Ukraine said Thursday its long-range drones had struck a major offshore oil platform in the Caspian Sea this week, signalling an expansion of its target list in a mounting campaign to cut off Russian energy revenues funding its war.

Meanwhile, Ukraine continues to strike Russia’s oil refineries and export ports, while Moscow keeps up its bombardment of Ukraine’s gas and power infrastructure. The attacks show no sign of easing while a breakthrough in the US-led peace plan remains elusive.

Sanctions pressure is escalating, hitting Russia’s LNG sector, shadow fleet, and—crucially—its top oil companies Rosneft and Lukoil.

The G7’s proposed plan to bar tankers from hauling Russian oil hinges on whether governments will ratchet up punishments on those skirting sanctions.

Ukraine's security services executed a long-range drone strike on Lukoil's Vladimir Filanovsky offshore oil field in the Caspian Sea, marking an unprecedented escalation against Russian energy infrastructure and raising new geopolitical risks for global energy logistics.

Russia's oil and gas revenues are projected to plunge by nearly 50% in December to a five-year low of $5.15 billion, driven by falling international oil prices, a stronger ruble, and widening discounts on Urals crude following U.

Prices for Russian crude shipments from its Black Sea and Pacific ports have fallen to their lowest levels since the full-scale invasion of Ukraine in February 2022, Bloomberg reported Tuesday, citing data from Argus Media.
