Ukraine hit Russia’s Tuapse refinery with drones for the second time in a week, part of a broader campaign targeting rail and oil sites. On Polymarket, odds for the Bab el-Mandeb Strait closing by April 30 sit at
Market reaction
The strikes have not moved odds on the Bab el-Mandeb Strait closure by April 30, which holds at
Why it matters
The Tuapse refinery is a major processing hub for Russian crude exports. Repeated strikes on energy infrastructure directly threaten revenue streams that fund Russia’s war effort. If Ukraine sustains this campaign against refineries and rail logistics, Russian crude supply could tighten enough to register in global pricing. The current Polymarket odds suggest traders view this as a real but not yet dominant factor in oil supply calculations.
What to watch
Watch for statements from Saudi Arabia’s Energy Minister and Russia’s Deputy Prime Minister on output changes, as these would directly affect supply expectations. EIA data releases and any OPEC+ meeting announcements could also shift trader positioning on the WTI April 2026 contracts. Further Ukrainian strikes on refining or export infrastructure would be the most direct catalyst for movement in these markets.
