## Prediction

Within 24 hours, senior US officials will reiterate in public fora that sanctions relief for Iran is contingent on full reopening of the Strait of Hormuz and verifiable surrender or removal of highly enriched uranium. Treasury’s explicit dismissal of Omani tolling proposals as a 'non-starter' and new sanctions on Iran’s Hormuz authority show Washington consolidating a hard baseline before Trump’s decision. Expect treasury or state to issue clarifying guidance or warnings targeting entities that might facilitate Iranian tolls or sanctions evasion. This will further narrow the political room for a quick, generous deal even if a ceasefire extension is eventually approved.

## Drivers

- US Treasury Secretary Bessent ruling out sanctions relief absent full Hormuz opening and HEU steps
- New US sanctions on Iran’s Strait of Hormuz maritime authority
- Explicit Treasury threat to 'aggressively target' any Hormuz tolling system including via Oman
