Trump's Iran ultimatum triggers oil market repricing over Strait of Hormuz chokepoint risk.

WHAT HAPPENED President Trump issued an ultimatum threatening Iran over potential Strait of Hormuz closure, prompting immediate energy market repricing. The threat targets the world's most critical oil chokepoint, through which approximately 21% of global crude oil transits daily. Oil futures spiked in overnight trading as geopolitical risk premiums were reassessed.

CHOKE-SHIPPING-001 activates through threat-based repricing rather than actual disruption. The causal chain runs presidential ultimatum → market perception of elevated closure probability → war risk insurance premium spikes for Persian Gulf tanker traffic → oil futures bid higher on tail-risk premium → broader energy complex follows crude higher. Secondary transmission occurs through strategic petroleum reserve drawdown expectations and alternative supply route capacity constraints.

Brent crude: strong bid above current $97.18, targeting $105-110 on sustained tension. WTI: sympathy move from $89.95, though Brent-WTI spread likely widens on Gulf-specific risk. Tanker equities (DHT, FRO): immediate beneficiaries of elevated day rates and war risk premiums. USO: direct crude oil exposure benefits. European refiners (Shell, TotalEnergies): margin compression on higher crude input costs. India-focused plays vulnerable given heavy Gulf crude dependence.

MEDIUM. Presidential threats carry credible escalation risk, but no immediate enforcement mechanism exists. Current oil prices suggest modest premium incorporation rather than panic buying, indicating measured market response.
