The dramatic shift in Russia's diesel exports has been a game-changer for global energy markets. Russia's diesel exports, once a bullish force, have now become a major bearish factor, and the reasons behind this sudden reversal are both intriguing and controversial. Let's dive into this complex story and explore the factors that have shaped this unexpected turn of events.
In early 2025, Russian diesel exports were a key driver of bullish sentiment in the global middle-distillate markets. However, by early 2026, the situation had taken a 180-degree turn, with Russian diesel becoming a bearish force, reversing a year-long surge in refining margins. The European diesel crack spread, which had risen to a peak of $34.17/bbl in November 2025, has now softened to an average of $21.7/bbl in January 2026. But here's where it gets interesting: this shift is not solely due to market dynamics, but also a result of Russia's resilience and the limits of sanctions.
The year 2025 saw a significant contraction in Russian diesel exports, with volumes falling to a five-year low of 586,000 b/d in September. This tightening was not a gradual process but a shock-driven one. It began with a Ukrainian drone strike on the Ryazan refinery, a 13.1 Mtpa plant, in January 2025. Repeated attacks throughout the year disrupted refining operations, with a record 14 drone strikes in November alone. Media reports indicate that more than 20 refineries were affected in 2025, with estimates suggesting around 20% of Russia's refining capacity was offline at various points due to strikes or maintenance. Refinery runs reportedly dropped to around 5 million b/d in September, prompting Russia to impose restrictions on diesel shipments and a temporary export ban for non-producing companies.
However, the tightness in the market began to ease in December 2025. Russian refinery runs recovered faster than expected, reaching an average of 1.8 million b/d in the first half of January 2026, the highest level since January 2025. Ultra-low sulfur diesel (ULSD) accounted for around 1.75 million b/d of this output. Overall refinery runs rebounded from 5 million b/d in September to approximately 5.5 million b/d in December. This recovery was unexpected, given the widespread belief that repairs would be prolonged due to restrictions on the sale of Western equipment and materials needed for restoration. Russian operators, it seems, have proven capable of restoring capacity more quickly than anticipated.
The rebound in output was not only visible in Russia's domestic market but also in its export flows. In December, the Tuapse refinery, an export-oriented plant, was damaged by a drone strike, yet loadings of ULSD resumed by mid-January. Kpler data shows two cargoes were loaded on January 10 and 14, destined for Turkey and Libya, respectively. The Primorsk oil terminal, in particular, saw a significant increase in loading, with the January program set to reach 2.2 million tonnes, a 27% month-on-month rise. This marks the highest loading level ever recorded at Primorsk, highlighting the growing importance of its Baltic Sea location as exporters redirect volumes away from the Black Sea, where Ukrainian attacks on Russian tankers have become more frequent.
Russian diesel exports, which had fallen to around 590,000 b/d in September, rebounded to approximately 900,000 b/d in December, a full year-on-year recovery. This rise in output has also led to a growth in Russian diesel stocks, reaching a reported three-year high of 27.6 million barrels. As a result, Russian energy authorities are discussing the removal of the ban on diesel exports by non-producing companies, arguing that domestic supply is now sufficient to meet internal demand, even during winter.
While the initial recovery in Russian diesel exports weighed on margins, the diesel crack spread has since firmed again, climbing to $25.43/bbl by January 21, 2026, due to colder temperatures and seasonal demand. This rebound is likely to encourage further Russian exports, especially to price-sensitive destinations where supply alternatives are limited.
Brazil is a prime example of a country heavily reliant on imported diesel due to chronic shortages in domestic refining capacity. Discounted Russian barrels are economically attractive to Brazil, but political risk and shrinking Russian supply led to a sharp curtailment of Brazilian purchases in the second half of 2025. Imports from Russia fell from 247,000 b/d in March to just 49,000 b/d in November, when new sanctions on Russian oil were put into effect. US diesel emerged as the primary substitute for Russian volumes in the autumn of 2025. However, these curbs proved temporary, and in December, Brazilian imports of Russian diesel rebounded to 181,000 b/d. This suggests that domestic supply gaps, favourable pricing, and growing fatigue with sustained US pressure outweighed concerns about friction with Washington. Moreover, Indian diesel exports to Brazil since November 2025 have been sourced almost exclusively from Nayara Energy's Vadinar refinery, a sanctioned facility partly owned by Rosneft, running exclusively on Russian crude.
Three key conclusions can be drawn from this complex situation. First, Russia has demonstrated remarkable resilience to drone attacks on its refining infrastructure. Operators have become increasingly capable of repairing damage quickly. Considering the tapering off of Ukraine's long-haul strikes on refineries, refinery utilisation is likely to remain stable. Second, as refining capacity continues to recover, Russia's need to export crude should diminish, potentially leading to lower crude exports in the future. Third, and perhaps most controversially, Western pressure to curb purchases of Russian oil products remains structurally weak. As long as Russian diesel is discounted and demand remains firm, economic incentives continue to outweigh political risk, a reality that has repeatedly asserted itself across global fuel markets.
This story is a testament to the intricate dynamics of global energy markets and the resilience of nations in the face of adversity. It raises important questions: Can economic incentives truly outweigh political risk? How will this situation evolve as the world navigates the complex web of energy politics?
