It does. Oil export is down after repeated attacks on ports and export infrastructure both on Black and Baltic sea and attacks on tankers in Black (and even Mediterranean) sea. Russia exports less oil than it extracts and will start shutting down oil wells soon (may be doing this already). Attacks on refineries also have impact on worlds petrol/diesel prices - one of biggest exporters turned into an importer at a time when there is world shortage of refining capacity and cracks spread is at or near all time high. > It also limits their ability to fund the war. It does but it also makes petrol and diesel more expensive around the world.
