US-Israel-Iran escalation threatens Strait of Hormuz oil transit and regional energy infrastructure

WHAT HAPPENED Direct military escalation between US-Israel and Iran threatens regional energy infrastructure, with Iranian crude exports representing approximately 3% of global supply. The conflict zone encompasses critical Strait of Hormuz chokepoint infrastructure, through which 21% of global petroleum liquids transit daily.

CONF-INFRA-001 activates: military action near energy infrastructure triggers insurance repricing and supply disruption fears. The causal chain runs conflict escalation → war risk insurance premiums spike for Persian Gulf tanker transits → crude oil futures reprice upward on supply threat premium → broader energy complex follows. Secondary transmission through Strait of Hormuz shipping delays forces inventory drawdowns globally.

Brent crude: already elevated at $103.90, expect additional $5-8 risk premium if conflict persists near Iranian export terminals. WTI: sympathy bid from $99.42, though US energy independence limits exposure. VIX: moderate uptick from current 17.83 as geopolitical uncertainty rises. Defense equities: direct beneficiaries of sustained regional conflict. European energy utilities: input cost pressure, monitor TTF gas futures for spillover effects. Gold: safe-haven bid likely from current $4,605/oz level.

MEDIUM. Iran controls critical infrastructure but conflict escalation depends on targeting decisions by all parties. Insurance markets will reprice immediately, but sustained premium requires credible infrastructure threats. Historical precedent from Abqaiq attacks showed rapid normalisation without follow-through.
