Oil markets partially retrace selloff as doubts emerge about durability of Iran–US arrangement
Theater: Global oil market

Moderate confidence (60%)
Risk direction: volatile · Impact: HIGH
Executive summary
Within 7 days, Brent and WTI are likely to recover part of their recent 5–6% losses, trading modestly higher as market participants reassess the durability of any informal Iran–US maritime arrangement and factor in persistent risks of spoilers. Intermittent IRGC or proxy actions, political backlash in Tehran or Washington, and continued restrictions on ‘hostile’ shipping will sustain a residual risk premium. Time spreads and crack spreads, especially for middle distillates, will remain supported by ongoing logistical frictions and war-related disruptions.
