## Prediction

Over the next 24 hours, persistent IRGC and Iranian media claims that the Strait of Hormuz is closed are likely to push Brent crude prices up by an additional 3–5% intraday and lift spot VLCC and LNG carrier rates from Gulf ports, even if enforcement remains ambiguous. Traders and insurers will price in non-trivial probability of physical disruption and regulatory or sanctions complexity for transiting vessels. This will tighten short-term liquidity in physical crude and LNG contracts, especially for Asian refiners and European utilities reliant on Qatari gas. Confirmation would be widening Brent–Dubai spreads, surging Gulf shipping insurance premia, and reported delays or diversions of tankers; denial would be clear AIS-based evidence of normal transit volumes and de-escalatory clarification from Tehran.

## Drivers

- Fars News repeated reports that Hormuz is closed and transit permits are withheld 'until further notice'
- FLASH alert describing Hormuz closure as most serious disruption in decades
- Emerging trend: Iran leveraging Hormuz closure threats as structured economic leverage in talks
