Full prediction

Over the next 24 hours, Brent crude prices are likely to remain above $100 per barrel with upside volatility, while war-risk insurance premia for tankers transiting Hormuz and the northern Arabian Sea rise sharply. Confirmed U.S. strikes on at least five Iranian crude carriers, Trump’s vow of “many more” attacks, and Iranian missile engagements against U.S. naval vessels substantially raise perceived disruption risk. Tanker operators will reroute, delay, or demand higher freight rates, tightening near-term crude and product availability, especially for Asian refiners dependent on Gulf supplies. Confirmation would be higher tanker war-risk quotes, surging TD3C (VLCC Persian Gulf–China) rates, and intraday Brent spikes; denial would be a surprise U.S.-Iran backchannel de-escalation or a clear lull in attacks acknowledged by both sides.
