Airstrike near Tehran escalates as Trump threatens Strait of Hormuz closure.

WHAT HAPPENED An airstrike targeted a building near Tehran as President Trump explicitly threatened closure of the Strait of Hormuz. The military action proximate to Iran's capital, combined with direct rhetoric regarding the world's most critical oil chokepoint, escalates conflict beyond previous symbolic strikes.

CONF-INFRA-001 activates: direct threat to critical energy infrastructure triggers immediate repricing. The causal chain runs airstrike near capital + strait closure threat → insurance markets reprice Iran/Gulf transit risk → war risk premiums spike for tankers → physical oil flows face disruption uncertainty → crude futures bid aggressively on 20% of global oil supply at risk. Secondary channel: geopolitical risk premium embeds in energy complex as conflict escalates beyond proxy warfare.

Brent crude: immediate 5-8% bid on supply disruption risk, current $97.18 vs FRED's lagged $127.61 suggests significant catch-up potential. WTI: sympathy move, 4-6% higher. War risk insurance: tanker hull premiums likely jump 0.5-1% of vessel value for Gulf transit. Defense contractors (LMT, RTX): direct beneficiaries. Short European refiners dependent on Iranian crude. Gold: safe-haven bid, already elevated at $4,863/oz but room for $5,000+ on acute escalation.

MEDIUM. Trump's explicit strait-closure rhetoric materially elevates tail risk probability, but infrastructure remains undamaged. Insurance repricing is mechanically enforceable, but sustained impact requires follow-through on threats.

Iranian retaliation against Gulf shipping infrastructure. JWC listing of Strait of Hormuz as war risk zone. Tanker insurance premium quotes exceeding 1% hull value. US military deployment announcements to Gulf region.
