**Summary**: Polish FM Sikorski stated Ukraine has destroyed an estimated 30–40% of Russia’s refining capacity. While this may overstate permanent damage versus temporary outages, it reinforces the scale of disruption underpinning elevated diesel cracks and product risk premia.

## Detail

The statement by Polish Foreign Minister Sikorski that Ukraine has destroyed an estimated 30–40% of Russia’s refining capacity is notable as a public, senior-level quantification of the impact of Ukrainian strikes on Russian energy infrastructure. Even if the figure includes temporarily disabled rather than permanently destroyed capacity, it underlines that a very large share of Russian refining has been disrupted at some point.

From a supply standpoint, actual sustained offline capacity is likely below 30–40%, as Russia has been able to partially restore operations, reroute crude to other plants, and adjust export mixes. Nonetheless, the campaign has:

- Reduced Russia’s ability to export refined products (especially diesel) at prior levels.
- Increased volatility in export volumes from key ports (e.g., Primorsk, Novorossiysk, Black Sea/Baltic terminals) as refineries cycle in and out of operation.
- Forced Russia to sell more crude relative to products or cut runs, tightening global middle distillate balances.

The public endorsement of high disruption numbers by an EU foreign minister is likely to:

- Reinforce bullish sentiment in middle distillates (ICE gasoil, ULSD) and maintain elevated crack spreads as traders reassess how quickly Russia can restore capacity.
- Support a structural risk premium in European diesel vs benchmarks given the EU’s dependence on non-Russian imports after its product embargo.
- Sustain concern about Russian fiscal and export revenue resilience, with some spillover to Russian-related crude differentials (Urals, ESPO) and potentially Russian sovereign risk pricing.

Historically, large-scale refining outages (e.g., US Gulf Coast hurricanes, Saudi Abqaiq 2019) have produced significant short- to medium-term jumps in cracks and regional spreads even when crude supply was adequate. The Ukraine–Russia dynamic differs because outages are staggered and partly reversible, but the cumulative effect highlighted by the 30–40% figure supports the thesis of a **structurally tighter** diesel market through at least the next 6–12 months.

This comment does not create new damage today but will likely entrench market expectations that: (1) Russian product exports remain structurally constrained, and (2) further strikes are politically tolerated. That bias is bullish for refined products and for Brent relative to lighter, product-rich barrels.
