Hormuz Crisis Likely to Push Brent Above 5–8% Intraday and Spike Tanker Insurance Rates

Risk direction: volatile · Impact: CRITICAL
Full prediction
Within 24 hours, Brent crude prices are likely to rise at least 5–8% intraday as markets absorb the declared Hormuz closure and multiple tanker hits, with spot tanker insurance premia for Gulf routes jumping sharply. Traders will price in sustained disruption risk rather than a one-off event, driving volatility in energy-linked equities and currencies of major importers. This will feed through to higher forward inflation expectations and may temporarily strengthen the US dollar as a safe haven. Confirmation would be Brent moving significantly above recent trading ranges and Lloyd’s or other insurers issuing surcharges; denial would be Brent remaining near pre-incident levels and insurers maintaining standard war-risk premia.
