## Prediction

In the next week, sustained risk around Hormuz will drive Asian refiners in Japan, South Korea, and India to increase purchases of Atlantic Basin and non-Gulf Middle Eastern crudes, even at higher delivered costs. This will strengthen differentials for North Sea (Forties), West African (Bonny Light), and US WTI Midland exports, while some smaller Asian buyers are priced out or forced to accept higher freight and insurance charges. Gulf producers may offer discounts to retain market share, eroding near-term fiscal buffers. Confirmation would be crude loading data showing higher Atlantic Basin flows into Asia and widening Brent-Dubai spreads; denial would be a rapid and credible maritime security agreement that normalizes Hormuz insurance rates.

## Drivers

- Attacks on a tanker near Hormuz and on US Gulf bases
- Conflicting signals about US–Iran talks sustaining a risk premium
- Shipowner sensitivity to war-risk insurance and route diversification
