Prolonged Hormuz Tension Keeps Brent Above $100 and Spikes Tanker Insurance Costs

Full prediction
If missile exchanges, mines, and blockade talk persist over the next week, Brent is likely to sustain levels at or above the $100/barrel mark, with spot tanker insurance premia for Gulf–Asia routes rising sharply. Charterers will face higher freight and war-risk charges, and some may delay liftings or seek non-Gulf barrels from West Africa, the U.S., or North Sea, reshuffling global trade flows. This will feed into higher refined product prices, especially diesel and jet fuel, and add pressure on inflation-sensitive central banks. Confirmation would be stubbornly elevated Brent futures, published increases in war-risk surcharges, and reported reallocation of tanker fleets away from the Gulf.
