The Strait of Hormuz Crisis: What Every Port Klang Shipper Needs to Know

On February 28, 2026, the United States and Israel launched military strikes on Iranian nuclear and military facilities. Within days, the global shipping industry was thrust into its most severe disruption since the COVID-19 pandemic. Iran retaliated by declaring the Strait of Hormuz closed to commercial traffic on March 4, backing up the declaration with attacks on vessels attempting transit. For Malaysian shippers moving cargo through Port Klang, the consequences have been immediate and far-reaching.

This article breaks down what has happened, how it affects your shipments, and what practical steps you can take to protect your supply chain.

What Happened: A Timeline of Escalation

The crisis escalated with alarming speed. On February 28, 2026, the US and Israel conducted coordinated strikes on Iranian targets. Iran's response was not limited to military retaliation against those countries directly. Instead, Iran targeted the most strategically valuable chokepoint in global trade: the Strait of Hormuz.

By March 4, 2026, Iran declared the strait closed. Iranian naval forces began intercepting commercial vessels attempting transit, with several ships attacked or seized in the first week. This was not an empty declaration. The Strait of Hormuz, a narrow passage between Iran and Oman at the mouth of the Persian Gulf, handles approximately 20% of the world's crude oil and liquefied natural gas (LNG) shipments. Closing it sent immediate shockwaves through global energy and freight markets.

The situation was compounded by Yemen's Houthi movement, which announced on February 28 that it would resume attacks on commercial ships in the Red Sea. This effectively closed two critical maritime chokepoints simultaneously, forcing vessels bound for Europe and the Mediterranean to abandon the Suez Canal route entirely and reroute via the Cape of Good Hope at the southern tip of Africa, adding two to three weeks to transit times.

The Oil Price Shock

Energy markets reacted immediately. Brent crude oil surpassed $100 per barrel on March 8 and continued climbing, reaching a peak of $126 per barrel as traders priced in the disruption to Gulf oil exports. For shipping, this matters beyond fuel costs. Higher bunker fuel prices feed directly into freight rates and surcharges. Every additional week a vessel spends rerouting via the Cape of Good Hope means additional fuel consumption, and at $126/barrel oil prices, those costs are substantial.

How the Global Shipping Industry Has Responded

The world's largest container shipping lines moved quickly to protect their fleets and crews. Maersk, CMA CGM, and Hapag-Lloyd all suspended transit through both the Strait of Hormuz and the Red Sea, redirecting vessels on longer alternative routes.

The scale of the disruption is significant. Approximately 170 containerships with a combined capacity of around 450,000 TEU (1.4% of the global fleet) became trapped inside the strait. These vessels, loaded with cargo, are unable to transit out until the security situation permits. For shippers with goods on those vessels, the wait is indefinite.

Carrier Surcharges

Carriers have responded to the increased costs and risks with a wave of surcharges:

These surcharges are in addition to the base freight rate increases already taking effect. They are applied per container, regardless of cargo value, and are subject to change with little notice as the situation evolves.

The Impact on Malaysian Shipping and Port Klang

Malaysia occupies a unique position in this crisis. Geographically, Malaysian ports are not on the direct Hormuz or Red Sea routes. However, the interconnected nature of global shipping means that disruptions at any major chokepoint ripple through the entire network. For shippers operating out of Port Klang, the effects are being felt across multiple dimensions.

Freight Rate Increases

Rates out of Port Klang have increased across the board, driven by global capacity reductions and carrier surcharges:

These figures represent averages. Specific trade lanes, particularly those connecting to Middle Eastern and European destinations, are seeing steeper increases. Air freight has been hit especially hard as shippers with time-sensitive cargo switch from disrupted sea routes to air, driving up demand and prices on already capacity-constrained air cargo lanes.

Port Klang Congestion

Port Klang is experiencing increased congestion as rerouted vessels create scheduling irregularities. Ships that would normally transit the Suez Canal are now sailing via the Cape of Good Hope, altering their port call sequences and arrival windows. This means vessels are arriving at Westport and Northport in clusters rather than the regular, predictable intervals that terminal operations are designed for.

For shippers, this translates to longer berth waiting times, delayed container availability, and increased risk of demurrage charges as containers sit at the terminal beyond their free-day allowance.

Malaysia's Diplomatic Position

In a significant diplomatic development, Malaysian and Thai vessels have been granted special access through the Strait of Hormuz following diplomatic talks between Kuala Lumpur and Tehran. This is a meaningful advantage for Malaysian-flagged vessels and their cargo, but it does not resolve the broader supply chain disruption. The majority of containers moving through Port Klang are carried on vessels flagged by other nations and operated by European carriers, which remain unable to transit the strait.

The Ghost Fleet Factor

An often-overlooked dimension of this crisis is the presence of 81 Iranian oil tankers in a "ghost fleet" anchorage approximately 70 kilometres off Malaysia's coast. These vessels, used to circumvent sanctions on Iranian oil exports, represent a pre-existing maritime security concern that has taken on new significance in the context of the conflict. Their presence complicates navigation in Malaysian waters and adds another layer of operational risk for commercial vessels operating in the region.

Why the Disruption Will Outlast the Conflict

Even when the military situation stabilises and the Strait of Hormuz reopens to commercial traffic, the logistics disruption will persist for months. This is a critical point that many shippers underestimate.

"When the war is officially over... that does not mean the war is over for logistics." — Hapag-Lloyd

The reasons are structural:

• Container repositioning: Hundreds of thousands of containers are currently in the wrong place. Containers that should be in the Persian Gulf are stuck on the wrong side of the closure. Containers rerouted via Cape of Good Hope are weeks behind schedule. Rebalancing this global container inventory will take months.
• Vessel schedule recovery: Every vessel that has been rerouted is now operating on a disrupted schedule. Carriers will need to blank sailings, adjust rotations, and rebuild their network schedules. This process typically takes two to three months even after the triggering disruption is resolved.
• Port congestion cascades: When the strait reopens, the 170 trapped vessels will begin moving simultaneously, creating a surge of arrivals at destination ports worldwide. This will trigger congestion events similar to what the industry experienced in 2021-2022 during the post-COVID recovery.
• Insurance and risk repricing: War risk insurance premiums for the Persian Gulf and Red Sea have already increased dramatically. Even after hostilities cease, insurers will maintain elevated premiums for an extended period, keeping surcharges in place.

Practical Steps for Malaysian Shippers

The current environment demands proactive supply chain management. Here are the actions we recommend for shippers operating through Port Klang:

1. Book Early and Confirm Space

With carriers reducing effective capacity through rerouting, available container slots are scarce. If you have shipments planned for the next three to six months, book as early as possible. Do not assume that space will be available at the last minute. Confirm your booking with your forwarding agent and request written space confirmation from the carrier.

2. Budget for Surcharges

The emergency conflict surcharges and war risk surcharges currently in effect should be factored into your landed cost calculations immediately. If you are quoting prices to customers for goods that will ship in the coming months, build these surcharges into your pricing. Absorbing $2,000-$3,000 per container in unexpected surcharges can eliminate your profit margin entirely.

3. Consider Alternative Routes and Modes

Depending on your cargo's origin and destination, alternative routing options may be available:

• Cape of Good Hope routing: Already the default for most carriers. Adds 10-14 days to Europe-bound shipments but avoids the conflict zone entirely.
• Trans-Pacific options: For cargo moving between Asia and the Americas, the Pacific route remains largely unaffected. Consider shifting procurement to suppliers accessible via Pacific routing if your Middle Eastern or European supply lines are disrupted.
• Rail alternatives: The China-Europe rail corridor (via Kazakhstan and Russia) remains operational for certain cargo types, offering a middle ground between sea and air on both cost and transit time.
• Air freight: At $2.80/kg, air freight is expensive but may be justified for high-value components, time-critical spare parts, or production-stopping materials. Calculate the cost of a production shutdown against the air freight premium.

4. Diversify Your Supplier Base

If your supply chain is heavily dependent on materials sourced from or routed through the Persian Gulf region, this crisis underscores the risk of geographic concentration. Begin identifying alternative suppliers in regions with more resilient shipping lanes. ASEAN-based suppliers, for example, can often be reached via intra-Asia shipping routes that are entirely unaffected by the Hormuz and Red Sea closures.

5. Strengthen Your Inventory Buffer

Just-in-time inventory practices, while efficient under normal conditions, leave no margin for disruption. If your business can sustain the working capital impact, consider building a two to four week safety stock buffer for critical materials. The cost of carrying additional inventory is almost always less than the cost of a production shutdown caused by delayed inputs.

6. Review Your Insurance Coverage

Ensure your cargo insurance covers war risk and conflict-related delays. Standard marine cargo policies may exclude losses arising from acts of war. Speak with your insurer or forwarding agent to confirm that your coverage is adequate for the current threat environment. This is especially important for cargo on vessels that may transit or be rerouted near conflict zones.

7. Work with an Experienced Forwarding Agent

In stable times, logistics can be managed with minimal active oversight. In a crisis, the difference between an experienced forwarding agent and a basic service provider becomes stark. You need a partner who monitors the situation daily, understands how carrier decisions affect your specific trade lanes, and can pivot your routing and booking strategy as conditions change.

How DNE Forwarding Helps You Through the Crisis

DNE Forwarding has operated through multiple shipping crises — from port strikes to pandemic-era disruptions to the Suez Canal blockage. Our approach during the Hormuz crisis is built on the same principles that have guided us through every disruption: proactive communication, practical solutions, and relentless attention to your cargo.

• Daily situation monitoring: Our operations team tracks carrier announcements, surcharge changes, and route modifications as they happen. You receive updates relevant to your shipments before they become problems.
• Carrier relationship leverage: As an ISO-certified forwarding agent with longstanding carrier relationships, we have direct communication channels with major lines including Maersk, CMA CGM, and Hapag-Lloyd. This means faster space confirmation and early visibility on schedule changes.
• Alternative routing advisory: We do not simply pass on carrier surcharges. We evaluate whether alternative routes, modes, or consolidation strategies can reduce your cost exposure. For some clients, a combination of sea freight via the Cape of Good Hope and selective air freight for critical components delivers the best balance of cost and reliability.
• Customs clearance speed: In congested port conditions, the speed of customs clearance directly affects your demurrage exposure. Our customs team at Port Klang pre-submits declarations and coordinates with Customs officers to minimise clearance time, keeping your containers moving out of the terminal as quickly as possible.
• Transparent cost communication: We provide detailed breakdowns of all surcharges and rate changes, with advance notice wherever possible. No surprises on your invoice.
• Warehousing flexibility: If rerouting or delays mean your cargo arrives before your facility can receive it, our warehousing capacity in the Klang Valley provides a buffer so you are not forced into expensive terminal storage.

Geopolitical disruptions are, by definition, beyond any shipper's control. But the impact on your business is not predetermined. The shippers who navigate this crisis most effectively will be those who act early, plan for extended disruption, and work with logistics partners who have the experience and infrastructure to adapt. The Strait of Hormuz will reopen eventually. The question is whether your supply chain can sustain the pressure until it does, and whether you are positioned to recover quickly when it happens.
