Mass Ukraine Drone Barrage Kills 3 in Russia Moscow

The large-scale drone attack on Russia, targeting infrastructure including near an oil refinery, creates a direct commercial mechanism for defense spending (air defense systems, drones) and potential supply disruption for Russian oil refining. The attack may lead to temporary refinery outages or reduced throughput, affecting domestic fuel supply and export capacity. The channel is supply_shortage (temporary disruption) and regulatory (increased defense budgets). Impact is region-specific (Russia) with global implications for oil product markets if refinery damage is significant.
