The Rerouting Cost Is Real. Here's Who Actually Pays For It.

Every shipping headline right now says the same thing: costs are up.

Freight rates up. Insurance premiums up. Transit times up. Fuel surcharges up.

What the headlines don't tell you is where those costs actually land in your supply chain — and how much of it ends up on your P&L whether you realize it or not.

What's Actually Happening to Shipping Right Now

Ships that previously transited the Strait of Hormuz are rerouting. The alternative is going around — longer routes, more fuel, more time, more exposure to elevated war-risk insurance premiums on the entire voyage.

Major shipping lines have already announced Hormuz avoidance. The vessels that are still attempting transit are facing insurance costs that make the economics marginal at best. War-risk premiums, which were near zero on most Asia-to-West routes six months ago, have spiked to levels not seen since the peak Red Sea disruption.

The result is a simultaneous hit on three variables that determine your landed cost: freight rates, insurance, and transit time.

The Three Cost Layers

Layer 1: Freight rate increases. When vessels reroute, effective capacity drops — the same ships are now spending more days at sea to move the same cargo. Less capacity, same demand, higher rates. This is the cost most buyers are aware of. It's visible on your freight quote.

What's less visible: rate increases are applying across routes that have nothing to do with Hormuz directly. The disruption tightens global vessel availability and reprices capacity everywhere.

Layer 2: Insurance premium surge. War-risk insurance premiums have spiked across the board. Your freight forwarder or carrier is paying more to insure cargo on every voyage. Some of that gets absorbed. Most of it gets passed through — either as explicit surcharges or baked into all-in rates that suddenly look different from last quarter's benchmarks.

If your cargo insurance is based on CIF value, your premium just increased on the same shipment, automatically.

Layer 3: Transit time extension. This is the cost nobody puts on an invoice — but it's real.

Longer transit means longer cash cycles. Your inventory is at sea for more days. Your working capital is tied up longer. Your ability to respond to demand changes narrows. If you're running lean inventory and your next container is now 12 days later than planned, the cost of that delay — stockouts, rush orders, lost sales, expediting fees — doesn't appear on a freight invoice. It appears in your operations.

Where It Shows Up in Your Supply Chain

At the factory: Energy cost increases are already squeezing factory margins in China, Vietnam, and India. Rerouting adds a logistics cost layer on top. Factories that supply components to your manufacturer are also absorbing higher transport costs. Those costs travel up the chain — either as price increase requests or as quiet adjustments to what goes into your product.

At the forwarder: Freight quotes from the last 30 days are not reliable benchmarks for the next 30. If you're booking shipments on rates negotiated before February 2026, expect conversations about surcharges, rate adjustments, or both.

At your customs entry: Customs value is typically based on CIF — cost, insurance, freight — to the port of import. If freight and insurance have both increased, your declared customs value may need to increase too. Higher customs value means higher duties on ad valorem tariff lines. This is not optional. It's a compliance requirement. Declaring last quarter's CIF value on this quarter's shipment is a valuation problem.

At your warehouse: If transit times have extended 10-15 days, your inventory planning assumptions are wrong. Safety stock levels calculated on previous lead times are now insufficient. The cost of being wrong shows up as stockouts, emergency airfreight, or both.

The Airfreight Trap

When sea freight gets complicated, the instinct is to airfreight.

Sometimes that's right. If the cost of a stockout exceeds the airfreight premium, you airfreight. That's a legitimate business decision.

But right now, airfreight capacity out of Asia is also under pressure. Cargo planes don't fly through the Strait of Hormuz, but the spike in demand for airfreight as a sea freight alternative is pushing air rates up simultaneously.

The calculation that made airfreight a viable emergency option three months ago is different today. Run the numbers before you commit — because the gap between sea and air has narrowed, and the justification threshold has changed.

Who Actually Absorbs the Cost

This is the question worth asking clearly.

In a normal market, cost increases in logistics get negotiated over time — some absorbed by carriers, some passed to shippers, some reflected in product pricing to end customers.

In a sudden disruption, the cost lands on whoever is holding the exposure at that moment.

If you have open purchase orders at fixed FOB prices, you're absorbing the logistics increase. The factory delivered to the port. What happens after is your problem.

If you have supply contracts with fixed landed cost targets, you're in a renegotiation — whether you've started that conversation or not.

If you have retail commitments at fixed prices, you're absorbing it all the way to margin.

The brands that manage through this are the ones who mapped their cost exposure before the disruption hit — who knew exactly where FOB ends and their risk begins, and had either contractual protection or operational flexibility to respond.

What to Do This Week

Reprice your open shipments. Pull every container currently in production or booked for the next 60 days. Recalculate landed cost with current freight rates, current insurance premiums, and extended transit assumptions. Find out now how far your margin has moved.

Check your customs valuation. If freight and insurance have increased materially, your CIF value has increased. Confirm with your customs broker that declared values on upcoming entries reflect actual costs — not last quarter's benchmarks.

Stress-test your inventory position. Add 10-15 days to every expected arrival and see where you have gaps. Address the critical ones now, before the container is already late.

Have the conversation with your factory. If you need to adjust order timing, volumes, or shipping terms, do it now. The longer you wait, the less flexibility you have — and the more the factory has already committed to logistics bookings on your behalf.

FAQ

Q: How much have freight rates actually increased since Hormuz closed? Rates vary by route and carrier, but war-risk insurance surcharges alone have added meaningful cost per TEU on affected routes. Spot rates on Asia-to-Europe lanes — which are most affected by rerouting — have moved significantly. Asia-to-US rates are less directly impacted by Hormuz but are being affected by global capacity tightening. Get current quotes rather than relying on contract rates negotiated before February 2026.

Q: Does the Hormuz disruption affect air freight from Asia? Yes, indirectly. Increased demand for airfreight as a sea freight alternative is pushing air rates up. Additionally, some air cargo routes cross Gulf airspace, which is subject to its own disruption. Get current quotes before assuming airfreight is available at historical rates.

Q: If my factory quotes FOB, am I protected from freight increases? On freight costs, yes — FOB means the factory's responsibility ends at the port of origin. But you're still exposed to the downstream effects: longer transit times affecting your cash cycle and inventory position, increased CIF value affecting customs duties, and higher insurance costs from the point of origin. FOB protects you from the freight invoice. It doesn't protect your landed cost.

Q: How long is this disruption likely to last? Nobody knows. The Red Sea disruption, for comparison, ran longer than most analysts initially projected and reshaped shipping economics for over a year. Planning for a quick resolution is optimistic. Building your operational decisions around an extended disruption — and being pleasantly surprised if it resolves faster — is the practical approach.
