A sustained blockade of Saudi-linked shipping through the Bab el-Mandeb Strait could create approximately $500 million to $2.5 billion in direct and near-term economic costs during its first month, based on ThePricer’s vessel-level scenario model.

A broader closure affecting nearly all commercial traffic could raise the first-month cost to approximately $2 billion to $10 billion. A simultaneous crisis at Bab el-Mandeb and the Strait of Hormuz would be far more damaging, but those losses should not be attributed to Bab el-Mandeb alone.

The estimate includes additional fuel, vessel time, charter expense, war-risk insurance, Suez Canal revenue losses, inventory delays, and incremental military protection. It does not count the full value of cargo passing through the region as if that cargo had been destroyed.

This distinction matters. Most ships can still sail around the Cape of Good Hope, and much of their cargo will eventually arrive. The primary economic damage comes from the longer journey, reduced shipping capacity, elevated energy prices, delayed production, and resources consumed without creating additional goods.

The immediate July 2026 threat is also more specific than a complete closure. Yemen’s Houthi movement declared a blockade aimed at Saudi Arabia, while selected vessels changed course and others continued through the strait. The situation may impose substantial costs without physically stopping every commercial ship.

• Targeted one-month blockade: approximately $500 million to $2.5 billion (at $30 per hour, earning that amount would take about 8 to 40 thousand years of full-time work, before taxes)
• Broad one-month commercial closure: approximately $2 billion to $10 billion
• Additional tanker voyage cost: roughly $2 million to more than $5 million in documented current cases
• Additional sailing time: as much as 30 to 34 days for some Saudi oil deliveries to Asia
• Current Red Sea traffic: already far below its pre-2023 level
• War-risk premium: recently reported near 0.75% of vessel value
• Main strategic risk: Bab el-Mandeb threatens the export route Saudi Arabia increasingly used to bypass Hormuz

How Much Would a Bab el-Mandeb Blockade Cost?

ThePricer modeled two one-month cases rather than applying one tanker example to every ship. The calculations use ranges because vessel values, destinations, cargoes, charter rates, speeds, and security decisions vary widely.

Cost category	Targeted blockade	Broad closure
Rerouting and additional vessel time	$180 million to $1.2 billion (about 2.9 to 19.2 thousand years of full-time work at $30 per hour)	$1.1 billion to $5.3 billion
Insurance and security	$45 million to $340 million	$100 million to $700 million
Additional Suez and port effects	$50 million to $250 million	$200 million to $800 million
Inventory and production delays	$100 million to $400 million	$500 million to $3 billion
Incremental military response	$100 million to $300 million	$300 million to $1.5 billion
Estimated first-month total	$500 million to $2.5 billion	$2 billion to $10 billion

The categories should not be treated as audited expenses. They are scenario estimates intended to show the likely order of magnitude and the assumptions required to reach it.

The lower targeted case assumes approximately three newly rerouted vessels per day at an average incremental cost near $2 million per voyage. Over 30 days, that produces approximately $180 million in direct rerouting expense:

3 vessels × 30 days × $2 million = $180 million

The upper targeted case assumes approximately eight affected vessels per day and an average incremental voyage cost of approximately $5 million:

8 vessels × 30 days × $5 million = $1.2 billion

The broad-closure range assumes approximately 25 to 35 affected vessels per day, with weighted incremental costs of $1.5 million to $5 million per vessel. Some ships would already be using alternative routes, some would make shorter deviations, and some would face costs above the average.

Why Bab el-Mandeb Matters Now

Bab el-Mandeb is the narrow southern gateway between the Red Sea and the Gulf of Aden. Ships traveling between the Suez Canal and the Indian Ocean normally pass through it. A vessel that cannot use the strait must generally travel around southern Africa or find a limited alternative involving pipelines, different ports, or transshipment.

The strait has become especially important to Saudi Arabia. After disruption at the Strait of Hormuz, more Saudi oil moved through the East-West Pipeline to the Red Sea port of Yanbu. That route reduced dependence on Hormuz but still required tankers serving Asian buyers to pass through Bab el-Mandeb.

The new risk is therefore not simply another Red Sea shipping problem. It threatens Saudi Arabia’s principal maritime workaround for avoiding the Persian Gulf chokepoint.

Reuters reported on July 20, 2026 that the Houthis had declared a naval blockade against Saudi Arabia. The Saudi-led coalition called the action illegal and said it was implementing measures to protect ships using Bab el-Mandeb.

The declaration did not immediately establish a complete physical closure. Some tankers reversed course, some waited, and others crossed the strait. Two Chinese-operated supertankers carrying a combined four million barrels of Saudi crude passed through Bab el-Mandeb on July 23, demonstrating that the corridor remained usable but increasingly risky.

Current Blockade Status

Condition	Status in July 2026
Houthi blockade declaration targeting Saudi Arabia	Confirmed
Threats against Saudi-linked shipping	Confirmed
Tankers reversing course or rerouting	Confirmed
Attacks involving Saudi oil tankers and infrastructure	Confirmed
Complete halt to all neutral commercial traffic	Not confirmed
Physical closure of the entire strait	Not confirmed

The distinction affects the cost estimate. A blockade limited to Saudi-linked tankers would involve fewer vessels than a general closure. However, commercial avoidance can spread beyond the stated target if insurers, crews, charterers, or corporate security departments determine that the route is unsafe.

Only 27 vessels crossed Bab el-Mandeb on one day following the declaration, according to ship-tracking data cited in current reporting. A single day does not establish a stable traffic level, but it shows the scale of the corridor and provides a useful reasonableness check for scenario modeling.

What a Blockade Actually Costs

A blockade does not produce one bill. It generates costs across several groups:

• Shipowners pay for fuel, crew time, machinery use, insurance, and longer voyages.
• Charterers pay for additional days and reduced vessel availability.
• Cargo owners absorb delays, inventory costs, and contractual penalties.
• Egypt loses Suez Canal toll revenue when traffic diverts away from the Red Sea.
• Governments pay for naval escorts, surveillance, air defense, port security, and minesweeping.
• Manufacturers may pay more for components or stop production while awaiting deliveries.
• Consumers may eventually pay higher freight, fuel, food, and product prices.

Not every payment is a net loss to the world economy. A higher freight charge is a cost to an importer but revenue to a carrier. An insurance premium is a cost to a shipowner but income to an insurer, although the insurer also accepts greater claim exposure.

The clearest economic loss comes from additional fuel burned, resources used to protect the route, damaged ships, spoiled cargo, idle factories, lost production, and time spent moving the same shipment over a longer route.

The Current Baseline Matters

A professional estimate cannot compare a July 2026 blockade with fully normal prewar traffic. Red Sea traffic had already declined sharply after attacks beginning in late 2023.

Lloyd’s List Intelligence data cited in June 2026 shipping coverage showed approximately 1,034 Bab el-Mandeb crossings during March 2026, compared with more than 2,000 in September 2023. That works out to about 33 crossings per day in March 2026, roughly half the earlier level.

The blockade’s incremental cost therefore depends on how many ships change their behavior after the new threat. Costs already embedded in Cape of Good Hope routes, existing war-risk premiums, and depressed Suez traffic should not be counted again.

UN Trade and Development reported that Suez Canal tonnage in May 2025 remained approximately 70% below its 2023 level. The latest blockade may deepen that disruption, but it did not create all of it.

Cost to Reroute One Tanker

The clearest current cost evidence comes from actual tanker routes.

One Saudi oil delivery to Asia that would normally take about 19 days was estimated to require approximately 48 days after rerouting. Fuel expense rose from approximately $1.26 million to $2.87 million (about 20 to 46 years of full-time work at $30 per hour), while a Suez Canal transit added about $1 million.

The total incremental expense was approximately $2 million to $2.5 million in the reported example, depending on the final route and operating assumptions. The ship also remained occupied for nearly an additional month, preventing it from completing another voyage.

Reuters calculated that the longer route nearly doubled fuel spending. Larger effects can occur when charter rates rise or a tanker must travel partially loaded because of canal draft restrictions.

Another current route added approximately 10,000 nautical miles and 34 sailing days. Estimated additional freight exceeded $5 million before fuel and insurance, with another $1 million potentially required for Suez transit, according to shipping-data analysis.

War-Risk Insurance

War-risk insurance is commonly quoted as a percentage of the vessel’s insured value for a limited period in designated high-risk waters.

Indicative Red Sea premiums reportedly increased from approximately 0.3% to 0.75% of vessel value following the blockade declaration. For a ship valued at $100 million:

• Premium at 0.3%: $300,000
• Premium at 0.75%: $750,000
• Additional premium: $450,000 per voyage

Insurance-market reporting also noted that Red Sea traffic had never fully returned to pre-attack levels. Some owners may choose a multimillion-dollar diversion even when insurance remains available because the policy cannot remove the danger to the crew or prevent operational disruption.

Hidden price: A quoted war-risk premium may not include cargo coverage, crew liability, deductibles, detention, cancellation, loss-of-hire insurance, armed security, or the cost of a vessel missing its next scheduled charter.

Suez Canal Revenue Losses

Egypt earned approximately $9.4 billion in Suez Canal revenue during fiscal year 2022/23, before the Red Sea crisis sharply reduced traffic. A simple monthly average at that historic level would be approximately $783 million.

It would be misleading to count the full $783 million as a new monthly loss from the July 2026 blockade. Much of the canal’s traffic and revenue had already disappeared.

UNCTAD documented a roughly 40% initial decline in canal revenue during the earlier Red Sea disruption, while later data showed that traffic remained depressed.

ThePricer’s current model therefore uses approximately $50 million to $250 million in additional Suez and port effects for a targeted blockade and $200 million to $800 million for a broader closure. The upper broad-closure figure approaches the historic monthly run rate but does not assume that every dollar represents a new loss.

Saudi Arabia’s Two-Exit Problem

Saudi oil ordinarily has two important maritime directions:

• East from Persian Gulf terminals through the Strait of Hormuz
• West through the East-West Pipeline to Yanbu on the Red Sea

Yanbu can protect some Saudi exports from a Hormuz disruption, but oil traveling from Yanbu to major Asian customers normally moves south through Bab el-Mandeb. If that route becomes unavailable, tankers may instead travel north through Suez and then around Africa, adding close to a month in some cases.

Saudi Arabia can also use Egypt’s SUMED pipeline, but capacity and tanker-size constraints prevent it from replacing every normal route. Current market analysis estimated that up to three million barrels per day of Saudi oil could require longer routing under a severe Bab el-Mandeb disruption.

Energy-market analysts noted that Suez, SUMED, inventories, alternative suppliers, and Cape routing could limit the damage, but none provides a free or unlimited substitute.

This is why a Bab el-Mandeb blockade could have a larger market effect in 2026 than a similar disruption during a period of normal Hormuz traffic.

Oil Prices and the Global Economy

A blockade does not need to destroy oil cargoes to raise prices. Longer routes reduce effective tanker capacity, postpone deliveries, increase replacement costs, and create uncertainty about future supply.

Oil flows through Bab el-Mandeb had already fallen from approximately 8.7 million barrels per day in 2023 to 4.0 million barrels per day through August 2024, according to the U.S. Energy Information Administration.

Those figures cannot be applied directly to July 2026 because shipping routes changed again after 2024. They do show, however, that millions of barrels per day can be diverted without disappearing from world supply.

Current analysts have discussed crude prices of approximately $115 to $120 per barrel in a severe disruption. Such forecasts depend on the status of Hormuz, emergency inventories, refinery demand, alternative production, pipeline capacity, and the duration of the crisis. They should not be presented as a guaranteed Bab el-Mandeb price.

A sustained oil-price increase could become more economically important than the direct shipping bill because it affects fuel buyers far beyond vessels using the strait. However, assigning the entire worldwide increase to Bab el-Mandeb would overstate its individual contribution when the region is already experiencing a broader energy conflict.

What Happens Over Time

Period	Most likely economic effects
First 24 to 72 hours	Oil-price volatility, insurance repricing, route reversals, vessel waiting
First week	Fuel and charter costs, security deployment, missed schedules
Weeks two to four	Port bunching, delayed inventories, higher freight rates, replacement cargoes
Months two and three	Factory disruptions, depleted safety stocks, food and fertilizer pressure
Beyond three months	New contracts, permanent rerouting, additional vessel deployment, inflation effects

Costs will not rise at a constant daily rate. Adaptation can lower some expenses as carriers establish new schedules and cargo owners change suppliers. Other costs can accelerate when inventories run out, charter markets tighten, or factories lack critical components.

A three-month estimate should therefore not be calculated simply by multiplying the one-month figure by three.

Who Ultimately Pays?

Shipowners initially pay for operating costs, but contracts determine how much can be passed to charterers and cargo owners. Importers may then include freight surcharges in wholesale prices. Manufacturers may pay for larger inventories, alternate suppliers, or emergency air freight.

Egypt absorbs lost foreign-currency revenue. Governments pay for military protection and diplomacy. Oil producers may receive higher prices while selling fewer or delayed barrels. Insurers collect larger premiums but face potentially catastrophic claims.

Consumers are most likely to notice the effects through diesel, gasoline, jet fuel, food, imported products, and delivery schedules. The mechanism resembles the way new maritime fees move through import prices, although a blockade adds physical delays and security risk rather than only a formal charge.

A combined threat to Hormuz and Bab el-Mandeb would also increase the cost of securing Middle Eastern shipping chokepoints, including escorts, surveillance aircraft, missile defense, drones, minesweeping, and replenishment vessels.

What Could Push the Cost Higher?

• A shift from a Saudi-specific blockade to attacks on neutral shipping
• Mines or damaged vessels physically obstructing the navigation channel
• Insurers withdrawing coverage rather than merely increasing premiums
• A prolonged Strait of Hormuz disruption occurring at the same time
• Damage to Yanbu, Jizan, pipelines, terminals, or Saudi storage facilities
• A shortage of available tankers and sharply higher charter rates
• Factory shutdowns caused by unavailable components
• Sustained rather than temporary increases in crude and refined-product prices

What Could Limit the Damage?

• Continued safe passage for neutral vessels
• Successful naval escorts and air-defense operations
• Use of Suez, SUMED, pipelines, inventories, and alternate terminals
• Spare tanker capacity and lower bunker-fuel prices
• A short blockade that ends before inventories become scarce
• Replacement oil from producers outside the affected routes
• Insurers maintaining coverage at manageable premiums

Answers to Common Questions

How much could a one-week Bab el-Mandeb blockade cost?

A targeted one-week disruption could produce approximately $125 million to $600 million in direct and near-term costs. A broad closure could cost approximately $500 million to $2.5 billion during the opening week, particularly if oil and insurance markets react sharply.

How much could a one-month blockade cost?

ThePricer estimates approximately $500 million to $2.5 billion for a Saudi-focused blockade and approximately $2 billion to $10 billion for a broad commercial closure. These ranges exclude losses caused independently by the Strait of Hormuz.

How much does it cost to reroute one tanker?

Documented current cases indicate approximately $2 million to more than $5 million, depending on fuel, vessel size, added days, charter rates, Suez charges, insurance, and destination.

Would a blockade stop world trade?

No. Ships can travel around the Cape of Good Hope, but the journey can add weeks, consume more fuel, and reduce the number of voyages each vessel can complete.

Is Bab el-Mandeb completely closed?

No complete physical closure of all commercial traffic had been verified in July 2026. The declared blockade targeted Saudi Arabia, selected tankers changed course, and other vessels continued through the strait.

Is all trade passing through the strait an economic loss?

No. Trade value measures the cargo exposed to disruption, not the amount destroyed. Much of the cargo may arrive later through another route. The economic loss consists of additional transportation, delay, shortage, damage, and lost production.

Could a Bab el-Mandeb blockade raise gasoline prices?

Yes. Longer tanker routes, reduced supply availability, and higher crude prices can increase refinery and transportation costs. The final effect depends heavily on the simultaneous status of Hormuz and other oil-export routes.
