Executive summary

Within 24 hours, Iranian IRGC units are likely to conduct limited coastal missile tests, UAV overflights, or close approaches to US and allied naval assets around the Strait of Hormuz rather than direct ship strikes. The aim will be to reassert Tehran’s claimed control of the strait and respond to the latest US strikes at Taherviyeh pier and other coastal sites without triggering full-scale war. This will heighten miscalculation risk for USN escorts, GCC navies, and commercial tankers transiting the choke point, potentially forcing temporary routing delays or escorted convoys. Confirmation would be radar- or AIS-linked reports of Iranian fast-boat swarms, UAVs, or anti-ship missile illumination near US vessels; denial…

Ukraine hits Russian oil pumping hub supplying Moscow, Baltic exports

Ukraine’s SBU says it struck Russia’s Vtorovo oil pumping station in Vladimir region for the second time this month. The facility feeds Moscow’s fuel system and is part of a Transneft network that also supports petroleum exports via Baltic ports, implying incremental risk to Russian product and crude flows and a modest upside risk to oil product cracks and Russian export differentials.

Reports: Ukraine Hits Russian Strategic Missile Plant, Oil Station Supplying Moscow

Ukrainian officials say FP-5 Flamingo missiles struck Russia’s Titan‑Barrikady defense plant in Volgograd overnight, while the SBU claims a second successful drone attack this month on the Vtorovo oil pumping station feeding Moscow and linked to Transneft exports. If damage is confirmed, Kyiv has demonstrated a deeper reach into Russia’s strategic missile and fuel infrastructure, raising both escalation risk and questions over the security of Russian energy and defense supply chains.

U.S. Strikes in Iran After Drone Attack on Hormuz Cargo Ship Revive Strait Chokepoint Risk

U.S. aircraft hit Iranian missile, drone and coastal radar sites after Tehran launched a suicide UAV at the cargo ship M/V Ever Lovely in the Strait of Hormuz, raising fresh questions about the durability of a fragile ceasefire.
