UPDATE: Strait of Hormuz tensions escalate: Tanker attacked after US-Iran exchange strikes; shipping threat level raised

Who it hits first

• Crude oil + LNG flowing through the Strait of Hormuz (~80% of India's crude imports) face delivery risk -> Brent spike risk reversing the recent -22%/1m fall to $73.21
• Tanker freight (VLCC/product carriers) and war-risk insurance premia spike
• Upstream producers (ONGC, OIL) gain on realizations; OMCs face marketing-margin squeeze; refiners face costlier feedstock with offsetting GRM widening

Who may gain

• ONGC, OIL — upstream crude realizations rise
• GESHIP, SCI — tanker freight + war-risk premia surge
