## Prediction

Within seven days, Washington is likely to move from signaling to concrete enforcement steps on expanded secondary sanctions against entities trading with Iran, forcing major Asian and European buyers, banks, and shipowners to curtail dealings. This will institutionalize a shift from episodic tanker seizures to a broader financial siege strategy, constraining Iran’s ability to monetize crude and product exports even absent full physical blockades. Tehran will respond with continued legal harassment of tankers in Hormuz, calibrated to avoid a direct U.S. naval clash but raising long‑term chokepoint risk. Confirmation would be formal Treasury guidance, compliance deadlines, and visible trade pullbacks; denial would be indefinite delay or watered‑down enforcement mechanisms.

## Drivers

- US Treasury signals of broadening secondary sanctions on Iran
- Iran’s public listing of 45 tankers for fines, detention, and cargo confiscation
- Extraordinary jump in Hormuz transit costs to $20m per VLCC
- Emerging trend of US–Iran conflict shifting toward systemic economic and energy warfare
