US-Iran hostilities rattle Hormuz oil traffic; India pulls seafarers off Hormuz transits as Iran readies Houthi Red Sea blockade

Who it hits first

• Indian shipowners lose access to Indian crew for Strait of Hormuz transits, constraining deployable tanker capacity (GESHIP, SCI)
• Refiners face higher freight and war-risk insurance on Gulf crude cargoes (CHENNPETRO, RELIANCE, HINDPETRO, IOC, BPCL, MRPL)
• Crude consumers with high cost weights absorb a Brent risk premium (SOTL 86.3%, AGARIND 80.9%, ASIANPAINT 40%, DABUR 25%)
• 265 Middle East flights cancelled and 1,139 delayed, hitting Gulf-route airline capacity (INDIGO)

Who may gain

• GESHIP and SCI: tanker charter rates and war-risk-adjusted freight rise; rerouting lengthens voyages and absorbs tonnage
• ONGC and OIL: crude realisations rise with Brent -- but the realised 2026 crisis precedent inverted this, with ONGC -12.17% over a month as Brent fell 22%
