Russia’s Ryazan refinery halts main units after attack

The significance here is less the strike itself than the loss of refining capacity at one of Russia's largest plants, which sits upstream of diesel and fuel oil flows that feed both domestic supply and export markets. That makes this a product-market story as much as an energy-security one, with knock-on relevance for distillate tightness and the tanker trades that move those barrels. Whether the outage is measured in days or weeks is the open question, and the absence of any damage or duration detail is precisely what leaves the market guessing.
