The sudden surge in Russia's diesel exports has sparked a fascinating debate in the energy sector. Russia's resilience and adaptability in the face of adversity have reshaped global trade routes and challenged conventional wisdom.
In early 2025, Russian diesel exports were a major factor in the global middle-distillate markets, but by early 2026, the situation had taken an unexpected turn. The European diesel market experienced a year-long surge in refining margins, with the diesel crack spread reaching a peak of $34.17/bbl in November 2025. This was primarily due to the acute shortage of Russian supply, which had been structurally weakened since the start of the war.
But here's where it gets controversial: as the year progressed, Russian diesel exports made a remarkable comeback. Despite refinery attacks and disruptions, Russian operators demonstrated an impressive ability to restore capacity and increase output. By December 2025, Russian diesel exports had rebounded to around 900,000 b/d, softening the cracks in the market and reshaping trade routes once again.
The tightening of diesel supplies in 2025 was a result of a series of events, including a Ukrainian drone strike on the Ryazan refinery in January, which accounted for a significant portion of Russia's refining capacity. Repeated attacks throughout the year further disrupted refining operations, with a record number of drone strikes in November. Media reports indicate that over 20 refineries were affected, leading to an estimated 20% of national capacity being offline at various points.
However, the situation began to turn around in December. Diesel cracks started to decline, reaching $19.89/bbl by mid-January, as Russian refinery runs recovered faster than anticipated. Russia's diesel output averaged an impressive 1.8 million b/d in the first half of January 2026, with ultra-low sulfur diesel (ULSD) accounting for the majority. Overall refinery runs rebounded from 5 million b/d in September to approximately 5.5 million b/d in December, defying expectations of prolonged repairs.
The rebound was not limited to output; export flows also increased significantly. Despite the damage caused by a drone strike on the Tuapse refinery, loadings of ULSD resumed by mid-January. Kpler data revealed two cargoes loaded on January 10 and 14, destined for Turkey and Libya. The Primorsk oil terminal, located in the Baltic Sea, recorded its highest loading level ever in January, with volumes increasing to 528,000 b/d. This shift away from the Black Sea highlights Russia's growing resilience and the limits of sanctions pressure.
And this is the part most people miss: the rising output has led to a buildup of Russian diesel stocks, reaching a reported 3-year high of 27.6 million barrels. Russian energy authorities are now discussing the removal of the ban on diesel exports by non-producing companies, arguing that domestic supply can meet internal demand, even during winter.
While the recovery initially impacted margins, the diesel crack spread has since firmed up again, reaching $25.43/bbl by January 21. This rebound is expected to encourage further Russian exports, particularly to price-sensitive destinations with limited supply alternatives.
Brazil serves as a prime example. Chronic shortages in domestic refining capacity make the country heavily reliant on imported diesel, making discounted Russian barrels an attractive option. Brazilian purchases of Russian diesel were curtailed in the second half of 2025 due to supply constraints and political risks. However, imports rebounded in December, suggesting that supply gaps, favorable pricing, and growing fatigue with US pressure outweighed concerns about friction with Washington.
Three key conclusions can be drawn from this situation: first, Russia has demonstrated remarkable resilience to drone attacks on its refining infrastructure, with operators becoming increasingly adept at quick repairs. Second, as refining capacity continues to recover, Russia's need to export crude is likely to diminish, potentially leading to lower crude exports. Third, Western efforts to curb purchases of Russian oil products remain structurally weak, as economic incentives often outweigh political risks.
The story of Russia's diesel exports is a testament to the dynamic nature of global energy markets and the resilience of nations in the face of adversity. It raises important questions about the effectiveness of sanctions and the balance between economic incentives and political risks. What do you think?
