Brent crude prices climbed to their highest level in four and a half months last week following attacks on multiple Russian oil refineries by Ukrainian drones. Additionally, this morning, drone strikes on two more oil refining facilities were reported deep within Russia. 

Bloomberg reports that drone strikes targeted two oil refining facilities in Russia’s Samara region, more than 620 miles from the Ukrainian border. 

A petroleum product processing unit caught fire on the territory of the Rosneft PJSC oil refinery in Syzran, RIA Novosti reported, citing Dmitry Azarov, the region’s governor. The plant’s design capacity is 8.5 million barrels per year or about 170,000 barrels per day.

Ukraine has been ramping up drone attacks on crude processing facilities across Russia.

On Wednesday, Rosneft PJSC’s Ryazan plant near Moscow was hit by a drone attack. This refinery is one of the largest in the country. A day earlier, a Lukoil refinery in western Russia was hit by a drone attack. 

The wave of drone strikes on Russian crude-processing facilities started in January, with full intentions by Ukraine to cripple the fuel supply that funds Moscow’s war machine. 

Here are the major Russian refineries that drones have targeted:

Last month, Ukraine’s “drone czar,” Minister of Digital Transformation Mykhailo Fedorov, explained to Reuters that its manufacturing base can produce thousands of drones capable of hitting targets at “300, 500, 700, and 1,000 kilometres.”

The full extent of the damage caused by strikes this year isn’t clear, but the attacks caused Moscow to place a six-month ban on gasoline exports starting on Mach 1. 

This week, the Brent crude market wasted no time pricing increasing war risks by sending prices above $85 a barrel, the highest level since early November. 

Despite two years of war and relentless attacks on Russian refineries, Moscow’s energy industry has proved resilient, and flows have shifted from Europe to China and India at heavily discounted prices. 

While Ukrainians target Russian refineries, David Asher, a senior fellow at the Hudson Institute, recently penned a note that discusses how the weaponization of crude could be the next big financial shock to the global economy. 

Given the mounting risks in the Middle East, Asher said on slide nine, “Global oil shock could trigger a crisis like 2007-2008.” 

He also noted, “Iran is Preparing for the Oil War: Markets Ignore Growing Risk.” 

Asher warned: It’s only a matter of time before Iran-backed Yemen’s Houthi rebels start targeting key oil facilities in Saudi Arabia. 

A perfect storm of higher crude prices continues to brew as the world’s refineries have become major targets.
