The Real Cost of Hormuz: What Saudi Suppliers Are Actually Carrying

Everyone budgeted for higher freight. Almost nobody budgeted for what actually happened.

The real Saudi cost of the Hormuz disruption is not a freight-rate story. It is port congestion, inland rerouting, mandatory and audit-driven stockholding, SAIBOR-funded working capital, and stockout risk — stacked on top of each other, on the same shipment, for the same customer.

That turns Hormuz from a logistics disruption into a cash conversion, compliance and service-level problem. A supplier who only re-prices freight will still be surprised by the invoice that follows.

The freight surcharge is the visible cost. The inventory sitting on the balance sheet is the one that changes the business.

This paper puts a number on both, using one consistent model across three Saudi supply-chain profiles: Aramco-facing petrochemical and oilfield suppliers, pharmaceutical suppliers under SFDA obligations, and general industrial importers. Every figure is reproducible from the assumptions in the final section, and every external claim has been checked against public reporting — noted inline where the evidence is a public rule versus Hala's own customer evidence.

The clearest signal is the shift in Saudi import gateways since the Gulf disruption began in early 2026. Kpler shipping data cited by AGBI shows Jeddah Islamic Port's share of ship calls into Saudi Arabia rising from 64% before the war to 76% by March 2026, while Dammam and Jubail — which together handled more than a quarter of Saudi imports before the disruption — saw import volumes fall by as much as 92%. Cargo has been pushed west, onto the Red Sea corridor, and into air gateways.

That shift creates a second-order bottleneck. Kuehne+Nagel's own port operational updates report Jeddah yard utilisation running around 89%, container-handling productivity down 20% to 25%, long waits for container release, and a Mawani rule requiring in-transit cargo to leave Saudi ports within 15 days of arrival or face penalties — with several carriers now declining in-transit bookings through Jeddah altogether.

What the customer actually pays for

The board-level point is simple. Saudi Arabia has alternative gateways. It does not have equivalent-cost gateways.

Carriers have already started pricing the alternative inland and landbridge flows this shift created.

Hapag-Lloyd suspended merchant-haulage cross-border cargo movement via Jeddah for consignees outside the Kingdom, and introduced alternative routing charges — reported in the thousands of dollars per container depending on container type and destination, with a confirmed US$1,000 dangerous-goods surcharge to Jeddah on top. Cargo destined for Dammam or Jubail continues to move through a Jeddah landbridge solution rather than direct discharge.

Maersk's Middle East operational updates confirm a US$25-per-TEU-per-day storage charge after an initial 14 days free, plus reefer plug-in and monitoring charges where applicable. Maersk has also suspended reefer bookings to and from Dammam, Al Jubail and King Abdullah Port, alongside several other Gulf destinations — leaving Jeddah as the one major Saudi gateway outside that suspension at the time of writing, which is exactly why so much traffic has concentrated there.

The clearest illustration of what this actually costs came via Reuters in March 2026: a Qatar-based distributor paid roughly US$10,000 per truckload routing energy drinks through Saudi Arabia's NEOM corridor, against roughly US$2,500 for pre-war maritime shipping on the same lane — a four-times increase, before counting the extra transit days it saved.

For Saudi customers, the inland cost is now driven by distance from Jeddah, Yanbu or King Abdullah Port to the final site; truck availability; container-return imbalance; bonded-movement complexity; reefer power and monitoring; cross-dock or postponement handling; priority-release fees; and demurrage and detention exposure. This is where most customers underestimate the bill. They budget for freight increases. They do not budget for rerouted-landed-cost increases.

This is the section that changes the conclusion of this paper, and it is worth being explicit about why.

For pharmaceutical suppliers, the six-month stock obligation is a published Saudi FDA rule, not an estimate. SFDA requires factories and warehouses dealing in pharmaceutical and herbal products to hold a permanent stock sufficient for six months of registered products, and to notify SFDA of an expected shortage or supply interruption at least six months in advance. Penalties can reach SAR 5 million, alongside facility closure or licence cancellation. NUPCO, the Kingdom's central platform for public-sector healthcare procurement, warehousing and distribution, exists in large part to manage exactly this shortage-and-availability problem across more than 300 hospitals and 2,500 clinics. Government purchasing represents roughly 54% of the Saudi pharmaceutical market, with local registered factories covering around 36% of market needs — so a pharma supplier cannot simply say 'out of stock' to its largest customer.

For Aramco-facing suppliers, the position is different and needs to be stated honestly. We did not find a public Aramco document setting a universal minimum-inventory rule for suppliers. Aramco's published supplier material — the iktva local-content programme, the Supplier Code of Conduct — addresses local content, quality and operational readiness, not a stated stockholding minimum. What we do have is direct customer evidence: Aramco-facing suppliers we work with report a six-month local postponement-inventory expectation, embedded in supplier audits, framework agreements and category requirements rather than published as a public rule. We treat that as commercially real and model it accordingly, while being explicit that it is customer evidence, not a citable public policy — and every Aramco-facing supplier should confirm the figure against their own contract and audit history rather than take it from this paper.

Why 'six months' is a different problem from 'one month'

The jump from one month to six months does not just scale the cost model. It changes what kind of problem this is — from an operating decision into a financing and compliance decision.

Hala models this across three Saudi supply-chain profiles, using one formula set and pathway-specific defaults for stock requirement, gross margin, gateway exposure and carrying cost. The defaults below are the guideline figures in Hala's Hormuz Cost Impact Calculator — a SAR150m annual-turnover, SAR120m annual-affected-supply-value business in each pathway. Your own turnover, volumes and margins will differ; use the calculator to run your actual numbers.

The financing rate behind every figure

Every pathway is financed at 12-month SAIBOR plus a bank margin. 12-month SAIBOR ran in the high-4% range through the first half of 2026 — 4.83% on 6 May and 4.91% on 11 June, per GIB Capital's daily market reports — giving a practical funding range of roughly SAIBOR + 150 to 350 basis points, or approximately 6.3% to 8.3% per year, depending on the bank and the facility. Full carrying cost — the APQC-defined total of cost of capital, storage, insurance, handling, administration, shrinkage and obsolescence — sits in a widely used industry planning range of 20% to 30% of inventory value annually for standard goods, rising to 25% to 40% for cold chain, dangerous goods, expiry-sensitive stock and slow-moving specialist spares.

The three profiles

The 'gross profit consumed' column is the sharpest way to read this table. On the petrochemical and pharma pathways, the modelled cost exceeds the entire annual gross profit the business generates — meaning the exposure is not a margin dent, it is margin-negative before anything else in the business is accounted for. Even the industrial pathway, with a shorter two-month stock requirement, consumes well over half of gross profit.

Six-month Saudi stock is the core cost driver on the petrochem and pharma pathways — the container surcharge most suppliers are watching is a fraction of the real number.

Put the corrected inventory maths at scale, and the message compounds. For every SAR100m of annual critical supply value, six months of minimum inventory creates SAR50m of stock on the balance sheet — and, at a 7.26% base-case funding rate, roughly SAR3.6m of annual finance cost above what a one-month model would have shown. Full carrying cost on that stock runs SAR10m to SAR15m a year at the standard 20–30% range, or SAR12.5m to SAR20m for cold chain, dangerous goods or slow-moving critical stock at 25–40%. That is before freight surcharges, inland diversion, port congestion, demurrage, detention or emergency airfreight.

Revised non-freight impact ranges

The trap is that a customer may see only a 3% to 7% rise in COGS on the invoices they actually review, while the inventory sitting quietly on the balance sheet erases a much larger share of gross margin than the invoice ever suggested. A business running fixed-price contracts or government tender pricing has no mechanism to pass that number through — it simply absorbs it.

One more distortion compounds the error. When shelves run short, historical sales data understates real demand, because it only records what was sold, not what was wanted. The correct measure is unconstrained demand — actual issues plus backorders, substitutions, urgent orders and emergency purchases — not a fill rate calculated against a stockout-suppressed baseline. A business that rebuilds its six-month stock requirement from constrained sales history will under-order, understock, and repeat the shortage.

This is where Hala should not be selling storage. The opportunity is to sell resilience-as-a-service — answering, for a specific customer and a specific SKU list, one question: how much stock must I hold, where must I hold it, how much cash does it consume, and what service failure does it prevent?

Five modules

The commercial message is deliberately simple. Freight is the visible cost. Inventory resilience is the hidden one. Hala helps customers quantify both, and hold the right stock in the right Saudi location — not the maximum stock everywhere, which just moves the cash problem instead of solving it.

For critical Saudi supply chains, the practical planning assumption is: model the required stock, finance it at 12-month SAIBOR plus bank margin, and apply a full annual carrying cost of 20% to 30% — 25% to 40% for high-risk categories — to the incremental stock. That gives a more honest view of the real Hormuz cost than freight rates alone.

Every figure in the three-pathway table is reproducible from Hala's Hormuz Cost Impact Calculator, using the guideline default profile for each pathway (SAR150m annual turnover, SAR120m annual affected supply value). Total annual cost impact = freight surcharge + inland transport + storage + inflation cost + risk cost + the incremental carrying cost of stock above a 1-month baseline. The calculator lets you replace every default — turnover, volumes, surcharges, stock requirement, funding rate, carrying cost — with your own numbers; the figures shown here are the published guideline case, not a quote.

A note on precision

Two figures deserve a specific caveat, because the source material behind this paper stated them more precisely than we could independently verify. The Q4-2025-to-March-2026 Saudi port-share shift is real and large — Jeddah's share of ship calls rose from 64% to 76% and Dammam/Jubail import volumes fell by roughly 92%, per Kpler data cited by AGBI — but we could not confirm exact decimal import-share percentages beyond that. And 12-month SAIBOR ran in the high-4% range through H1 2026 (4.83% in early May, 4.91% in mid-June, per GIB Capital), rather than a single confirmed rate on a single date. Both are stated here at the precision we could actually verify.
