## Prediction

Oil and credit markets are likely to react within a day to the US Treasury chief’s pledge of the “toughest sanctions in history” on Iran by nudging Brent and Oman/Dubai benchmarks higher and widening Middle East sovereign CDS spreads. Traders will anticipate tighter enforcement on Iranian crude exports, increased tanker risk, and more aggressive secondary sanctions on buyers, especially if China appears even partially cooperative. The move will reinforce a global energy risk narrative that competes with recession fears, affecting inflation expectations and rate-path pricing in major economies. Confirmation would be a measurable uptick in Brent and EM energy credit spreads with commentary linked to Iran sanctions; denial would be stable or falling prices despite heavy media coverage of the sanctions threat.

## Drivers

- US Treasury Secretary promising 'toughest sanctions in history' on Iran
- Explicit call for Chinese cooperation on Iran oil
- Existing trend of maximalist US economic pressure on Iran
