The Next Stage of the Hormuz Disruption: Inland Bottlenecks, Air Cargo Inflation, and Cost Pass-Through

Carrier notices were the first wave. The bigger story now is what happens after the detour: alternative-port strain, air cargo substitution, and inland cost pass-through are turning a maritime disruption into a broader network problem.

The first phase of the Hormuz story was easy to recognize. Vessels rerouted. Carriers issued advisories. War-risk and bunker-related charges started appearing in customer inboxes. That phase mattered, but it was still the visible part of the disruption. The more important shift now is that the impact is no longer staying on the ocean leg. Cargo is being pushed through alternative ports, inland workarounds are expanding, urgent shipments are moving into air, and new cost pressure is showing up beyond sea freight.

That is the real second-stage risk for operators. Once a chokepoint disruption starts spreading into secondary ports, trucking capacity, inland handoffs, and urgent-mode substitution, lead times become harder to predict even when cargo is technically still moving. The problem is no longer only “Can the vessel transit?” It becomes “What happens to the shipment after the network has been rerouted around the original path?”

Why this stage matters more than another carrier notice roundup

Reuters reported on March 16 that importers and logistics providers across the Gulf were already redirecting cargo through ports such as Fujairah, Khor Fakkan, and Sohar. Those alternatives help keep freight moving, but they do not offer the same scale as the region’s biggest hubs, which means diversion itself can create fresh congestion and delay. Reuters also described companies expanding trucking capacity and staging cargo through additional nodes in India, Pakistan, Jeddah, and Sokhna to maintain supply flows.

That is why this is no longer just a carrier-advisory story. A routing disruption becomes a network disruption when the workaround introduces new pressure points. A shipment that avoids one chokepoint may now face inland transfer complexity, secondary-port dwell risk, truck capacity strain, or less reliable ETA assumptions at the next step. The disruption has not ended. It has changed shape.

Signal #1: The detour does not end at sea

The simplest mistake in a situation like this is to treat a detour as a one-line operational change. In practice, rerouting a shipment around a major chokepoint changes what happens at discharge, what inland mode picks up the cargo, how long transfer windows remain realistic, and how much slack exists if another node becomes constrained. Reuters’ latest reporting shows exactly that pattern: cargo is not just taking a different sea path, but moving through a wider emergency routing architecture involving smaller ports, inland trucking, and temporary staging points.

For forwarders and shipper ops teams, this matters because alternative routing often looks workable on paper before it starts compounding in execution. A booking may remain bookable. A vessel may still sail. But the inland leg may be slower, more expensive, or less predictable than the original transport plan assumed. That is where customer frustration often begins: not at the moment of the headline, but several steps later when quoted lead times no longer match the network that now exists.

Signal #2: Air cargo is absorbing urgency

One of the clearest signs that the disruption has moved beyond ocean freight is what is happening in air cargo. Reuters reported on March 13 that air freight rates had climbed by as much as 70% on some affected routes as conflict disrupted Middle East airspace and ocean shipping patterns at the same time. Reported lane moves included South Asia–Europe up 70% to $4.37/kg, South Asia–North America up 58% to $6.41/kg, and Europe–Middle East up 55% to $2.79/kg.

That matters even for teams that do not regularly buy air. When disrupted ocean networks start pushing urgent or high-value cargo upward into air, the result is broader capacity pressure, higher exception-management costs, and tougher prioritization decisions. Air is not a clean substitute for ocean, and Reuters noted it can cost five to ten times more. But when stockout risk, perishability, service-level commitments, or production continuity are on the line, some cargo owners will still make that switch.

In other words, air cargo inflation is not a side story. It is evidence that the network is reallocating urgency. That is exactly the kind of second-order signal operators should watch, because it shows where disruption is starting to override normal transport logic.

Signal #3: Cost pass-through is moving inland

The next important shift is commercial. Earlier in the month, much of the attention was on emergency fuel, bunker, and war-related charges tied to the ocean leg. That is no longer the full picture. Reuters reported on March 19 that CMA CGM would introduce an emergency fuel surcharge on land transportation from March 23, explicitly saying that rising fuel costs were affecting all transport modes.

Hapag-Lloyd has also published new inland emergency fuel and energy surcharge notices in Europe. For Portugal and Spain, the carrier said that effective March 23 for non-FMC trades and April 14 for FMC trades, it would apply a new inland diesel component of 8% on truck and 4% on combined rail. For North Europe, Hapag-Lloyd said that effective March 23 for non-FMC trades and April 17 for FMC trades, inland emergency fuel surcharges would apply at country-group-specific levels including 5%, 13%, and 15%.

The point is not that one carrier updated one tariff line. The point is that disruption-related cost pressure is now showing up beyond the sea leg. That has two consequences. First, teams reviewing only ocean freight surcharges may miss part of the landed-cost change. Second, carrier notices that once looked like isolated commercial updates start to form a broader pattern: the network workaround itself is getting more expensive.

What operators should review now

First, review quote validity windows and exception clauses. In a network like this, a quote that looks commercially acceptable today can become operationally stale very quickly if inland routing assumptions or secondary-port conditions change. The risk is not only a surcharge appearing later. It is that the original quote logic was built for a route and transfer pattern that no longer exists.

Second, expand cost review beyond the ocean leg. If disruption is moving into land transport and alternative nodes, then inland haulage, transshipment handling, urgent-mode escalation, and buffer inventory decisions all deserve the same attention that bunker or war-risk surcharges received in the first phase. Ocean-only review is now too narrow.

Third, separate shipments by urgency instead of treating all bookings the same. Reuters’ reporting on rising air cargo rates shows that some shippers are already paying a premium to protect critical flows. That does not mean everything should move by air. It means ops teams should decide explicitly which SKUs, orders, or customers justify mode escalation and which can tolerate longer, less certain inland rerouting.

Fourth, update customer communication before the ETA miss, not after it. In a first-stage disruption, customers usually expect visible delay. In a second-stage disruption, they are more often surprised by uncertainty that appears later in the chain: secondary-port congestion, handoff delays, inland repricing, or repeated ETA revisions. The best communication at this stage is not false precision. It is a clearer explanation of where the new volatility sits.

The takeaway

The biggest risk now is not only the chokepoint itself. It is the way chokepoint disruption spreads through the rest of the logistics network before planning assumptions catch up. Carrier advisories were the first wave. The more important story now is what happens after the detour: pressure on alternative ports, substitution into air cargo, and inland cost pass-through that can reshape lead times and landed cost well beyond the original maritime leg.

For shippers and forwarders, that means the right question is no longer just whether freight can move around Hormuz. It is whether the rest of the transport plan still works once the cargo has been rerouted. Right now, that is where the real execution risk is building

When disruption spreads beyond the sea leg, the first challenge is often not movement itself but visibility: knowing where the shipment is, how the routing has changed, and what that means for ETA confidence and customer communication.
