Insurance killed Hormuz before the military did. Premiums 0.25% → 5% in 10 days (20x), eased to ~2.5% by late Mar, then re-spiked after Apr 2 escalation, MSC Ishyka strike (Apr 4), Iran rejecting ultimatum (Apr 5), and Kharg Island strikes (Apr 7). 2-week ceasefire agreed Apr 7 — premiums dropped from 3.5% (Apr 8) to ~2.5% (Apr 10), then reversed higher to 3.5% (Apr 12) after Islamabad talks collapsed and Saudi East–West pipeline strike. Mid-April (Apr 14) shows cautious stabilization at ~3.25% as underwriters reassess, but Hormuz remains classified “very high risk.” Shippers placing huge volume requests; strait still effectively closed with Iran charging $1M+ tolls. Maersk not yet resuming; 800 vessels still trapped. US-nexus vessels pay 2x more.

US military blockade of Iranian ports takes effect at 10 AM ET. Trump: 'doesn't care' about new talks. Brent crude nears $100/bbl (+40% since war began). Shipments restricted by >90% (~10M bpd oil off market). Premiums spike on blockade risk.
