## Prediction

Within 24 hours, Iran is likely to issue clarifying notices, fines, or inspections against at least one of the 45 tankers it has threatened in the Strait of Hormuz to sharpen its leverage before U.S. secondary sanctions expand. Tehran will calibrate action to raise insurance and legal risks without triggering immediate Western military retaliation. This will pressure Asian refiners and shipowners to reassess routing and contracts, feeding into diplomatic scrambling in Europe and Asia. Confirmation would be publicized IRGC or port authority actions on specific tankers; denial would be a pause with only rhetorical threats.

## Drivers

- Iran’s explicit threat to fine/detain 45 tankers in Hormuz
- Reports of forthcoming U.S. expansion of secondary sanctions on Iran
- Extraordinary spike in Hormuz transit costs to $20m per VLCC
- Escalation trend toward economic and energy warfare in US–Iran confrontation
