## Prediction

Within 24 hours of the Treasury Secretary’s pledge of the "toughest sanctions in history" on Iran, Washington is likely to initiate coordinated but mostly non-public outreach to EU capitals, Japan, South Korea, and India to signal a coming spike in enforcement efforts. The message will stress ship-to-ship transfer tracking, insurance scrutiny, and pressure on intermediaries handling Iranian crude, while specifically urging China-facing partners to avoid backfilling lost supply. This would lay the diplomatic groundwork for later secondary sanctions and heighten perceived compliance risk for refiners and shipping insurers. Confirmation would include background leaks to major financial media on new US "Iran enforcement" tasking; denial would be visible allied reluctance or public distancing from increased measures.

## Drivers

- US Treasury Secretary’s public vow to impose the "toughest sanctions in history" on Iran oil
- Explicit US call for Chinese cooperation on Iran energy flows
- Historical US pattern of coalition-building before major sanctions enforcement ramps
