US Strikes Larak.
Iran Hits Jordan Bases.
Last Monday Washington framed the week as a ledger war — Operation Economic Fury, a “greatest financial offensive,” and a naval blockade that redirected commercial ships away from Iranian ports. This weekend the kinetic clock restarted. U.S. Central Command said American forces struck IRGC rocket launchers on Larak Island after observing preparations to fire sea mines into the Strait of Hormuz. Iran answered with ballistic missiles at U.S. bases in Jordan. Brent jumped back above ninety dollars. The strait that once carried a fifth of the world’s oil remains, for practical purposes, closed.

Welcome to Issue #29. U.S. forces struck IRGC mine-launch prep on Larak Island; Iran retaliated with ballistic missiles at U.S. bases in Jordan. Brent climbed back above $90 on the exchange of fire. Drewry cooled one percent to $4,473 after last week's surge. Panama's September stack arrives this week: 48.0 feet on September 2, slot cuts from September 3.
This Week’s Briefing
Larak Island: The Kinetic Clock Restarts
Last week’s digest closed on Treasury Secretary Scott Bessent’s “greatest financial offensive” and a Hormuz weekend that saw fewer than twenty commodity vessels. The Trump administration had, for about a month after late July, shifted emphasis toward economic pain and naval redirection rather than new strikes on Iranian territory. That framing lasted until Sunday.
U.S. Central Command said American forces took “limited, precise action” against IRGC minelaying forces on Larak Island — a small Iranian island near Bandar Abbas at the mouth of the Strait of Hormuz — after observing rocket launchers preparing to fire sea mines into the waterway. Multiple outlets, citing U.S. officials and CENTCOM spokesperson Navy Captain Tim Hawkins, said the strike destroyed two launchers. Hawkins said CENTCOM had completed clearing sea mines from international shipping routes last week and framed the action as protecting commercial shipping. Iranian media reported explosions near Larak; the IRGC acknowledged fighters and civilians killed or wounded and vowed retaliation.
The operational stakes are blunt. Hormuz remains the energy chokepoint that, before this conflict, moved roughly one-fifth of globally traded oil. Al Jazeera’s August 27 wrap, citing Kpler, put average daily vessel traffic from mid-July through August 23 at about five ships — a roughly ninety-five percent drop from pre-war levels. Clearing mines and then watching launchers reload is the difference between a managed risk and a re-closed corridor. For shippers, the tell is still insurance acceptance and carrier routing notices — not whether a press release calls the waterway “cleared.”
| Signal | Reading | Source / context |
|---|---|---|
| Larak strike | Two IRGC rocket launchers (mine prep) | CENTCOM / Reuters / Axios, Aug 30–31 |
| Prior US strike lull | ~1 month since late July | Euronews; last prior US strike cited Jul 29 |
| Mine clearance claim | International routes cleared prior week | Capt. Tim Hawkins / CENTCOM |
| Hormuz traffic | ~95% drop; ~5 vessels/day avg | Al Jazeera Aug 27 citing Kpler |
Treat “mines cleared” as a temporary state until carriers and P&I clubs price it. A re-mining attempt is exactly the risk last week’s Economic Fury week did not erase.
Iran Strikes U.S. Bases in Jordan
On Monday the IRGC said it launched ballistic missiles — and in some statements, a combined missile-and-drone operation — at U.S. forces at the King Hussein and Al Azraq bases in Jordan in response to Larak. Jordan’s armed forces said they intercepted eight missiles that entered Jordanian airspace and reported no injuries. Early U.S. assessments cited by Fox News described no significant impact and near-complete interceptions. Iranian outlets also claimed follow-on targeting of U.S. assets in the UAE (Al Minhad) and, separately, a downed U.S. MQ-9 over Hormuz; treat multi-country and drone claims as developing until CENTCOM and host governments confirm scope. Markets also had to ignore a Trump Truth Social post with an AI-generated clip implying Kharg Island was under attack — CENTCOM did not report a Kharg strike.
The IRGC’s statement, carried by Fars and state media, framed every U.S. attack as met with “even more devastating responses” and rejected efforts to weaken Iranian control of Hormuz. That language matters for logistics because it ties retaliation explicitly to the strait — not only to sanctions lists. After last week’s ledger war, operators again face a dual risk stack: OFAC / Economic Fury counterparty screening on one side, and war-risk / routing / delay pricing on the other.
| Signal | Reading | Source / context |
|---|---|---|
| IRGC targets (claimed) | King Hussein & Al Azraq (Jordan) | Iranian media / Stars and Stripes / Al Jazeera Aug 30–31 |
| Jordan intercepts | 8 missiles; no injuries reported | Jordan armed forces statement |
| US impact assessment (early) | No significant impact; nearly all intercepted | Fox News citing US source |
| Other claims (developing) | UAE Al Minhad; MQ-9 downed; Kharg AI rumor | Iranian media / Al Jazeera; not CENTCOM-confirmed |
| CENTCOM blockade tally | 82 redirected; 3 disabled; 2 boarded | CENTCOM as of Aug 28 |
Update war-risk and schedule contingencies for any Middle East–adjacent string, not only Gulf-origin cargo. Retaliation geography now includes host-nation bases outside Iran’s borders.
Brent Back Above $90 on the Exchange of Fire
Last week Brent wrapped near ninety-three dollars with Hormuz traffic in the teens. Early this week the kinetic exchange pushed the tape again: Brent traded roughly in the low nineties on August 31 — wraps cited prints from about ninety dollars thirty to ninety-one dollars twenty-five — up roughly two to three-and-a-half percent on the day as markets priced Larak and the Jordan retaliation. Trading Economics and related wraps noted traders still estimate six to eight million barrels per day — mainly non-Iranian Gulf producers — continuing to transit under escort or constrained conditions, even as Iranian export pathways remain under blockade and sanction pressure.
Carrier Emergency Fuel Surcharges filed in August remain the baseline. A one-day oil pop does not automatically rewrite every EFS notice — but it removes any leftover mid-August argument that fuel relief was imminent because diplomacy was “close.”
Reprice fuel lines against current carrier notices and Monday’s Brent print — not against last week’s Economic Fury headline alone.
Drewry Cools to $4,473 — Expensive Soft Landing
Last week’s four-percent surge to four thousand five hundred twenty-six was the loudest Transpacific print of late August. This week Drewry’s World Container Index for August 27 fell one percent to four thousand four hundred seventy-three — still far above mid-summer cooling levels near four thousand three hundred, and still expensive in absolute terms.
Lane detail shows a softer New York print and a flat West Coast: Shanghai–New York fell two percent to nine thousand three hundred thirty-three; Shanghai–Los Angeles held at six thousand eight hundred eighteen. Asia–Europe eased again — Rotterdam down three percent to four thousand two hundred eighty-seven; Genoa down two percent to four thousand eight hundred sixty-six. Capacity tools shifted: Transpacific blank sailings announced for next week fell to four from seven, while Asia–Europe blanks rose to four from two. Shanghai congestion worsened sharply — average vessel waiting time jumped to ninety-six hours from thirty-five the prior week.
| Signal | Reading | Move |
|---|---|---|
| Drewry WCI (Aug 27) | $4,473 / 40ft | −1% after prior week +4% to $4,526 |
| Shanghai–NY | $9,333 / 40ft | −2% |
| Shanghai–LA | $6,818 / 40ft | Flat |
| Shanghai–Rotterdam | $4,287 / 40ft | −3% |
| Shanghai–Genoa | $4,866 / 40ft | −2% |
| Shanghai vessel wait | 96 hours | Up from 35 hours |
| TP blanks next week | 4 | Down from 7 |
Do not mistake a one-percent composite dip for cheap freight. Quote the lane, the blank risk, and Shanghai dwell together — especially with Panama’s September cuts arriving this week.
Panama’s September Stack Arrives as Hormuz Stays Closed
Last week’s postponed calendar is now the live calendar — with one important correction from ACP Advisory A-29-2026. Neopanamax draft steps to forty-eight feet TFW on September 2. Neopanamax slots cut to nine per day from September 3 (with Panamax slots also adjusting). The further draft cut to forty-seven point five feet TFW — previously scheduled for September 3 — was postponed to October 1. Canal congestion and auction-slot costs have already spiked on energy-export demand diverted by Middle East disruption — Asia Business Daily’s August 30 wrap cited express transit fees at multi-year extremes and waits of up to eleven days without a reservation.
For Asia–East Coast planners, that is the Western Hemisphere tell: Hormuz does not need to sit on your bill of lading for Gulf conflict to tighten Panama, fuel, and schedule risk on the same quote. Do not conflate this week’s slot cut with the deferred 47.5-foot draft step.
Lock weight plans before September 2 for the 48.0-foot step; treat September 3 slot scarcity as a booking-window risk; keep October 1 on the draft calendar for 47.5 feet.
Two Risk Stacks, One Quote
This week returned kinetic exchange to a crisis that last week looked like a ledger war. Larak and Jordan-base retaliation belong on the war-risk and routing checklist — insurance acceptance, carrier notices, schedule contingency. Operation Economic Fury and OFAC screening belong on a separate counterparty checklist. Neither stack replaces ocean, fuel, duty, or Panama surcharge lines on the all-in quote.
Drewry's one-percent dip to four thousand four hundred seventy-three is still a high plateau, not cheap freight. Brent in the low nineties keeps August Emergency Fuel Surcharges relevant. Panama's September 2 draft step and September 3 slot cut arrive regardless of whether missiles or sanctions dominated Monday's headlines.
Quote kinetic risk, sanctions exposure, ocean, fuel, duty, and Panama constraints as separate lines — not one blended crisis surcharge.
💡 Palletizr Tip of the Week
When Economic Pressure and Missiles Share the Same Week
Do not rebuild September’s risk model from last Monday’s sanctions headline alone. Rebuild from the sailing — and the free-time clock.
- Separate lull from reopen. A month without US strikes on Iranian soil was not a reopened Hormuz. Book against traffic and insurance, not against the last quiet week.
- Keep war-risk and OFAC on different checklists. Jordan-base retaliation is a routing/insurance problem; Economic Fury is a counterparty problem. Both can hit the same shipment.
- Model Panama and detention together. The September 2 draft step, September 3 slot cut, and ninety-six-hour Shanghai waits burn free time — keep October 1’s 47.5-foot draft on a separate calendar line. Put demurrage next to ocean on the all-in quote — see our detention & demurrage guide.
Next Watchpoint
September 2: Panama Neopanamax draft steps to 48.0 feet TFW — update weight plans before gate-in. September 3: Neopanamax slots cut to nine per day. October 1: further draft cut to 47.5 feet TFW under ACP A-29-2026.
