What changed in the last two weeks?
The Strait of Hormuz disruption went from scenario planning into day-to-day execution for shipping teams.
UN Trade and Development published a rapid analysis on March 10, 2026, tying the shock to energy, fertilizer, and transport cost pressure.
This same week, JMIC advisories showed Strait traffic dropping from a historical average near 138 vessels per day to single digits, with four confirmed commercial transits in the prior 24 hours in its March 6 update.
JMIC also said there was no universally recognized legal closure, yet the operating environment looked like a near stop due to security threats, insurance constraints, and carrier caution.
BY THE NUMBERS, WHAT THE STRAIT MEANS TO GLOBAL TRADE
38% of global crude oil • 29% of LPG • 19% of LNG and refined oil products
13% of chemicals and fertilizers • 2.8% of container traffic

What did prices do right away?
UNCTAD data through March 9 showed a sharp move in energy markets between February 27 and March 9: oil up 27% to $91.8 per barrel and gas up 74% to EUR 55.8 per megawatt hour.
For ecommerce brands, that move is substantial since fuel and marine energy costs feed into ocean contracts, drayage, and parcel pricing with a lag.
A brand can hold stable volume and still face a landed-cost jump once surcharge tables reset.
How global carriers are reacting
Carrier action moved quickly from alerts to execution.
MSC instructed Gulf-bound and in-region vessels to move to designated safe shelter areas.
CMA CGM suspended bookings across multiple Gulf markets and rolled out an emergency conflict surcharge in early March.
Hapag-Lloyd announced war-risk charges and booking restrictions for reefer cargo and intra-Middle East trades.
Maersk published repeated Middle East contingency updates, temporary booking suspensions for multiple Gulf lanes, and a temporary Emergency Bunker Surcharge with global application from March.
Why should a U.S. ecommerce operation care if it does not route through the Gulf?
The first reason is fuel pass-through.
When bunker and energy inputs rise fast, carrier surcharges can spread past the conflict zone.
The second is network spillover.
When vessels hold, reroute, or wait for new instructions, congestion shifts into alternate ports and feeder legs.
The third reason is schedule variance.
Mean transit time can look manageable while ETA reliability drops hard, and that is what hurts promotional calendars and replenishment plans.
Where do margins get hit first?
Margin pressure shows up in three places.
One is at purchase-order level, where low-margin SKUs absorb extra freight with no pricing room.
Another is at inventory-timing level, where late receipts force split shipments, air expedites, or stockout loss.
The third is at customer-experience level, where delivery promise windows miss and support contacts rise.
These effects do not show up cleanly on day one, which is why weekly controls matter right now.
What teams ought to do in the next 14 days
- Reforecast landed cost each week with current surcharge sheets and two fuel scenarios.
- Reclassify inbound POs into protect, defer, and cancel buckets using gross margin and sales velocity.
- Add buffer units on top sellers where stockout cost is higher than carrying cost.
- Lock alternate port and routing playbooks with your 3PL before containers hit a handoff point.
- Tighten promise-date logic on PDP and checkout so customer messaging matches current ETA variance.
- Run a daily control room across merchandising, finance, ops, and CX until advisory cadence slows.
What to watch for through April & beyond
Watch carrier advisory pages for new booking restrictions, surcharge scope expansions, and restart signals for suspended lanes.
Track whether Strait transit counts move from single digits toward stable daily flow.
Monitor bunker and energy direction after March 25, when new surcharge frameworks start showing up in invoices.
If de-escalation signals become durable, transit reliability should improve before full cost normalization.
