Sustained Hormuz War Risk Pushes Medium-Sour Crude Spreads to Multi-Month Highs

Risk direction: escalatory · Impact: CRITICAL
Full prediction
Over the next 7 days, the effective removal of Iranian crude and the war‑zone conditions in Hormuz will likely drive medium‑sour crude grades (such as Basrah, Arab Medium) to trade at multi‑month premia relative to light sweet benchmarks. Refiners in Asia and Europe that rely on these grades will scramble to secure alternative supplies from Saudi Arabia, Iraq, and potentially Russia, accepting higher differentials. This will increase refined product prices and strain import‑dependent economies with weaker currencies. Confirmation would be marked tightening of Dubai/Oman versus Brent spreads and higher premiums for Saudi and Iraqi term cargoes; denial would be only marginal spread movement, suggesting traders expect a quick de‑escalation.
