What we know on the 11th day of the US and Israel’s war with Iran

An estimated ~20% of global oil supply is disrupted on day 11 of the conflict, creating a major market shock and elevated energy-price risk. Humanitarian and military escalation is severe — 1,700+ killed, hundreds of thousands displaced, Israel and Iran exchanging strikes, and the Strait of Hormuz effectively contested — increasing geopolitical tail risks. Policy responses (G7 discussions on strategic reserve releases, South Korea fuel caps, Pakistan austerity measures, and unspecified US 'waivers' on some oil sanctions) point to acute near-term volatility and sustained risk-off positioning in energy and regional emerging-market exposures.

Analysis

Primary market transmission will be through transport and insurance economics rather than crude geology alone. A sustained functional closure of the Strait of Hormuz forces VLCCs and Suez-maxes to add 7–10 days per voyage (10–20% longer voyages), which historically translates into a multi-week surge in earnings (VLCC TCE up 3–5x) and a concurrent 200–500bps widening of refined product spreads as displacement logistics strain coastal refinery offtake. Insurance (war-risk) premia for Gulf transits will reprice upward quickly; a 2–3x jump in premia materially raises delivered fuel costs to Asia and Europe and creates a persistent kink in tanker economics even if crude flows resume. Second-order winners are capital-light shipping owners, marine insurers/reinsurers, and mid/long-cycle defense contractors; losers include short-cycle refiners dependent on Middle East heavy crude differentials, airlines, and EM sovereigns with high import bills. A temporary SPR release or coordinated G7 sell-off can cap headline spikes within 30–60 days, but rebuilding strategic stockpiles, war-risk insurance normalization, and physical rebalancing take 3–9 months — creating a tradeable window for asset owners that can wait out volatility. Tail risks skew to escalation: direct attacks on export infrastructure or a blockade of alternative routes would push Brent into materially higher regimes (we model $120–180/bbl in a persistent 20% supply outage scenario over 1–3 months). Conversely, discrete diplomatic breakthroughs or a rapid, credible release of 200–300M barrels from coordinated SPRs could reverse price moves in weeks; position sizing must therefore combine optionality with rate-insulated exposures.
