📝 Executive Summary
Ukraine said its forces struck Russia’s Taneco refinery and a smaller oil terminal on August 20, 2026, adding to a string of attacks on Russian energy assets. The strike raises the prospect of reduced Russian refining runs and fuel exports, which would tighten global supply and underpin crude and product prices. Traders will watch for damage assessments and any disruptions to Russian seaborne crude flows as geopolitical risk returns to the oil market.
