Hormuz Watch — Daily Maritime & Energy Intelligence Digest

Date: 2026-07-20 (Mon) · Coverage window: Jun 23 – Jul 20 (gap-bridge since last digest; emphasis last 72h) Bottom line: The June de-escalation has fully collapsed. Strait of Hormuz is again effectively closed to commercial traffic — IRGC has banned unauthorized transits and asserted “full control,” while CENTCOM has reimposed its naval blockade on Iranian ports and is running nightly strike waves. Both sides are enforcing rival transit regimes at sea. Only de-escalatory note: Iran signaled today that talks with the United States “could be pursued based on national interests.”

1. Situation snapshot

Ceasefire collapse: On 25 Jun — a week after the MoU — an Iranian drone struck a cargo ship in the strait, igniting a chain of tit-for-tat hostilities now bordering on all-out war.
19 Jul (IRGC statement): Four vessels “violated maritime navigation instructions” — two suffered an unspecified incident after entering an “unsafe lane,” two aborted and turned back. IRGC now demands prior authorization for oil/gas/chemical cargoes and warns non-compliant vessels risk the same fate.
20 Jul: All maritime traffic reported banned in the strait; Israel is reportedly readying to resume direct strikes on Iran.
Iran claims 46 killed, 400+ wounded since US strikes resumed. IRGC threat: “not a single drop of oil or gas will be exported from the region” while US operations continue.

2. Shipping & transit traffic

Transit collapse: ~10 ships transited 12 Jul vs ~88/day pre-war norm; fell to 8 on Thu 16 Jul (from 15 the prior day). Strait now effectively at zero pending IRGC “authorization” regime.
≥9 ships attacked since 6 Jul as Iran forces traffic into its territorial-water “controlled routes” — 40+ IRGC patrol boats patrolling and escorting vessels on the Iranian-designated lane.
14 Jul: Attacks on MT Al Bahiyah and MT Mombasa killed one Indian seafarer, wounded several; India summoned Iran’s envoy in protest.
Stranded: ~100 container ships trapped in the Persian Gulf; ~6,000 seafarers stuck in-region. IMO warns against Hormuz sailings while working evacuation corridors.

3. Naval operations

Blockade reimposed (14 Jul): CENTCOM restored the naval blockade on Iranian ports/coastal traffic — 20+ US warships, hundreds of aircraft in theater. Two blockade-runners redirected within the first 17 hours; a tanker skirting the blockade was struck 15 Jul.
Strike campaign: Ninth consecutive night of strikes completed as of today; 80+ targets hit including missile/drone sites, naval assets, coastal defenses, underground storage, and the IRGC maritime-surveillance tower at Chah Bahar. Strikes have expanded to northern Iran and to bridges/power stations in the south.
Escorted flow: US says 8M+ barrels transited on Sun 12 Jul under military assistance — the emerging model is contested, convoy-style movement, not open passage.
Regional spillover: Qatar and Kuwait fended off Iranian missile/drone attacks (16 Jul); Kuwait intercepted several.

4. Oil & energy markets

Brent Crude (Sep) ~ $88.47/ bb l * * t o d a y, b r i e f l y * * ab o v e$ 90 intraday — up from ~$78.80 on 9 Jul (~12% in under two weeks); 1-month highs on the escalation.
Prices erased gains today after Iran’s talks signal — the market is trading headlines, not fundamentals.
Pre-war the strait carried ~20% of global oil trade (~20M bbl/d capacity); flows now a fraction of that, moving only under escort or via pipeline bypass.

5. Logistics & insurance

War-risk premiums: 3–10% of hull value (vs 0.25% pre-war) — $3-10 Mp er t r an s i t o na$ 100M tanker; pricing ~8x pre-crisis with 6 P&I clubs withdrawing cover. Maritime-risk executives call it the “worst case scenario.”
Container spot rates: China→US East Coast +75%, →N. Europe +51%, →Med +45%; Asia–Europe/Asia–India lanes +30–50%.
Bypass limits: Saudi East–West pipeline to Yanbu + UAE ADCOP to Fujairah = ~9M bbl/d combined — less than half of strait capacity. Cape of Good Hope rerouting adds 3,500–4,000 nm and 10–14 days.
Insurance re-entry — the June unlock sequence (corridor certification → insurer re-entry → rate rollback) — is now fully reversed.

6. Diplomatic track

Doha talks deadlocked: Two weeks into the 60-day window the parties were still disputing the signed MoU — Iran claims joint sovereignty (with Oman) and post-window tolls; US rejects both. Donald Trump publicly abandoned the Hormuz fee concept 14 Jul.
The 60-day toll-free window (from ~18 Jun) nominally runs to ~mid-August but has been overtaken by events on the water.
Today’s signal: Tehran says US talks “could be pursued based on national interests” — first de-escalatory language since the collapse. Treat as probe, not pivot, especially with Israel posturing to re-enter.

7. Watch items (next 24–72h)

Does the IRGC transit-authorization regime get tested — and does any vessel comply with it (a de facto toll/sovereignty win for Tehran)?
US convoy/escort ops vs IRGC patrol boats: highest-probability flashpoint for a direct naval engagement.
Brent Crude holding above $90 — watch for sustained break on any Israel re-entry or tanker strike.
Full war-risk market withdrawal (remaining P&I clubs) → would zero out even escorted commercial movement.
Iranian retaliation against Qatar/Kuwait basing; GCC air-defense engagements.
Follow-through on Iran’s talks signal; any back-channel venue announcement.
Stranded-fleet drawdown: ~100 boxships, ~6,000 seafarers, IMO evacuation progress.
