Ukraine Strikes Russian Oil Ports: How These Attacks Are Cutting Putin’s Revenue.

How Ukraine Is Reducing Russia’s Oil Profits

According to TSN.ua: Ukraine is carrying out large-scale strikes on Russia’s key ports and oil refineries, aiming to cut Moscow’s oil revenues and weaken the aggressor’s economy. A primary target is oil infrastructure that supplies a major portion of Russia’s petroleum income.

The Baltic route is critical for Russian oil traffic, handling 45% of tanker transshipments. Black Sea ports also play a key role, accounting for 40% of tanker transshipments. Other routes, including the Far East and the North, make up only 15%. As a result, attacks on strategic infrastructure can significantly impact the Kremlin’s financial capabilities.

Strikes on Oil Refineries

A crucial part of Russia’s refining capacity is the Kirishi refinery in Leningrad Oblast, which processes over 10% of the country’s oil. On March 27, 2026, explosions were reported at strategic oil infrastructure sites, including the ports of Ust-Luga and Primorsk, following drone strikes. These actions could lead to major economic losses for Russia. As expert Pavlo Lakiychuk noted:

‘If these leak points are sealed off, the billions Putin is counting on will never reach him.’

Through these attacks, Ukraine aims to hit military fuel depots, which could create a domino effect for the Russian army, reducing its combat capability. In this way, Ukraine continues its strategy of countering the aggressor by targeting key sectors of Russia’s economy.

These events highlight the importance of energy security in the context of the war in Ukraine. Systematic strikes on Russian oil refining infrastructure could substantially reduce the financial resources the Kremlin uses to fund its military operations. In turn, this could lead to a decline in Russia’s military activity, marking an important step toward stabilizing the region.
