The Iran war is rewriting global shipping maps. With the Strait of Hormuz effectively closed to commercial traffic since the end of February, and the Red Sea-Suez Canal route once again deemed too dangerous for ocean carriers, the world's largest container lines have reverted to long-haul routings around the Cape of Good Hope. Maersk, CMA CGM, Hapag-Lloyd and MSC are all keeping their main Asia-Europe and Asia-Mediterranean services well away from the Middle East, dashing earlier hopes that 2026 would see a sustained return of container traffic to the Suez route.

Between 1 March and 24 April, an average of around 20 commercial vessels rounded the Cape every day, more than three times the level recorded over the same period in 2023, according to industry tracking data. Transit times between Asia and Europe have lengthened by roughly two weeks. Fuel consumption is up 30-50 per cent on each rotation, and operators have had to add 10-20 per cent more vessels into their loops to maintain weekly service frequency. The combined effect is a meaningful lift to the cost of moving a 40-foot container between Shanghai and Rotterdam, with knock-on consequences for global Supply/">Supply chains, retail pricing and freight company Earnings/">Earnings.

For the Egyptian state, which depends on Suez Canal transit fees for a significant share of its hard-currency Revenue/">Revenue, the development is acutely painful. For Asian and European exporters and importers, it is a familiar but unwelcome return to a high-friction logistics environment. For shipping investors, who had spent much of late 2025 modelling a normalisation in spot rates, it is a fresh reminder that the freight cycle remains a function of geopolitics as much as of pure Supply/">Supply and Demand/">Demand.

How the Suez route was lost again

Container lines had spent late 2025 cautiously reopening selected services through Bab el-Mandeb and the Suez Canal, encouraged by an extended lull in Houthi attacks and by the operational and financial costs of the Cape diversion. Some carriers had begun routing limited tonnage through the Red Sea on a vessel-by-vessel basis, with enhanced security protocols and selective customer pricing. The expectation, articulated publicly by several chief executives, was that 2026 would see a gradual but meaningful return of capacity to the shorter route.

Those plans were upended in late February when the United States and Israel launched coordinated air strikes against Iran. The conflict that followed brought direct disruption to Strait of Hormuz traffic, the closure of significant Iranian and regional ports to international shipping, and a renewed wave of attacks by Iran-aligned forces against vessels transiting the southern Red Sea. Insurance underwriters reacted decisively, with war-risk premiums spiking and a growing number of underwriters refusing cover for vessels transiting either the Strait of Hormuz or the Red Sea bounded by Yemen and Eritrea.

By mid-March, all the major container lines had once again diverted Asia-Europe and Asia-Mediterranean services around the Cape. Maersk paused additional bookings for the Middle East region. CMA CGM and Hapag-Lloyd issued customer guidance confirming that all main-haul vessels would route via southern Africa for the foreseeable future. MSC instructed masters to avoid both the Bab el-Mandeb and the Strait of Hormuz and temporarily suspended bookings to and from the Middle East.

The cost of the Cape detour

The Cape route is around 3,500 nautical miles longer than the Suez route on a typical Asia-Europe rotation. The extra distance translates directly into a longer voyage cycle, more fuel burn, more crew time and additional bunker calls. Shipping consultants estimate that, for a typical loaded ultra-large container vessel, the all-in cost of a Cape rotation is between 30 per cent and 50 per cent higher than the equivalent Suez voyage, even before higher port congestion charges and capacity Rebalancing/">Rebalancing costs are included.

To preserve weekly cadence on individual loops, carriers have had to insert additional vessels — typically one to two extra ships per Asia-Europe service. This has tightened the global Supply/">Supply of large-vessel capacity, supporting freight rates on routes that have nothing direct to do with the Middle East. Trans-Pacific and Asia-Latin America routes have seen knock-on rate firmness as carriers redeploy capacity, an effect familiar from the post-2023 Red Sea disruption.

For shippers, the impact is more than just freight. Inventory levels have been adjusted upward at many warehouses to absorb the longer transit time, Capital/">Working Capital/">Capital has had to expand to cover goods in transit, and just-in-time Supply/">Supply chain practices that were already under pressure have come under further strain. The biggest losers are sectors that combine relatively thin margins with sensitivity to lead times, including parts of fast fashion, lower-priced electronics and certain seasonal consumer goods.

Egypt and the Suez Canal Authority

Egypt's Suez Canal Authority has now endured two consecutive years of substantially reduced traffic, having only just begun to record some recovery in late 2025. Suez Canal transit fees are an important component of the Egyptian state's hard-currency receipts, and Revenue/">Revenue shortfalls compound a wider set of fiscal pressures that the country has been managing with the support of the International Monetary Fund and Gulf creditors. Egyptian officials have continued to engage with international shipping lines and with maritime insurers to explore mitigations — including potential discounts on canal fees and enhanced naval coordination — but those measures cannot offset the underlying security concerns.

The political resonance is also significant. Egypt's role in the wider Middle East diplomatic constellation, its security relationships with the Gulf, and its long-running engagement with both Israeli and Iranian-aligned interlocutors all intersect with the canal's commercial position. A prolonged disruption to canal revenues will have lasting consequences for Egypt's macroeconomic trajectory and could shape regional diplomacy in ways that go beyond the immediate freight implications.

Other regional ports — Salalah, Jebel Ali, Sohar, Aqaba — have all been affected to varying degrees, with some seeing a temporary reduction in transhipment activity and others benefiting from rebalanced flows. Bunker fuel suppliers, port operators and a wider ecosystem of maritime service providers across the Gulf and the Red Sea have had to adjust quickly to a fundamentally changed operational environment.

Carrier Earnings/">Earnings and the freight cycle

For container carriers themselves, the impact on Earnings/">Earnings is decidedly mixed. On one hand, longer voyage cycles burn more fuel and consume more Capital/">Capital. On the other, they tighten the effective Supply/">Supply of vessel capacity, supporting freight rates above where they would otherwise be in a year that had been forecast to deliver substantial new vessel deliveries. Maersk, MSC, CMA CGM, Hapag-Lloyd, COSCO, Evergreen and ONE have all flagged Cape routings as a meaningful Factor/">Factor in updated full-year Earnings/">Earnings guidance.

Spot freight rates from Asia to Europe and the US East Coast have risen sharply since the Iran war began, although they remain below the post-Covid peaks. Forward contract pricing for the back half of 2026 has firmed, with shippers increasingly willing to pay for service certainty. Freight forwarders, who manage the relationship between carriers and individual shippers, have found their margins squeezed in some segments and expanded in others, depending on contract structure.

Analysts who follow the listed carriers have generally raised Earnings/">Earnings estimates for the year, while warning that the favourable rate environment is fundamentally a function of geopolitics rather than of structural Supply/">Supply discipline. A sudden ceasefire that allows the rapid resumption of Suez transits would be expected to deflate spot rates quickly, in much the same way that previous post-conflict normalisations have seen rates fall faster than carrier Capital/">Capital plans can absorb.

The Cape route as a new normal

A growing body of analysis is exploring whether the Cape of Good Hope route — long viewed as the back-up choice — will become a more permanent feature of global shipping. Repeated periods of conflict-driven Suez disruption since 2023 have made it increasingly difficult for carriers and shippers to model a stable Suez environment. Some logistics planners argue that the long-run fragility of the Suez route now warrants a structural reorientation around the Cape, with associated Investment/">Investment in southern African port infrastructure, bunkering capacity and crew-change networks.

South Africa's port and shipping authorities have responded with measured optimism, recognising the opportunity but also the operational challenges of handling a sustained increase in transhipment, bunker and ship-services Demand/">Demand. Cape Town, Durban and other ports have invested in capacity, but local infrastructure has been constrained by long-running operational issues that limit how rapidly the country can absorb additional Volume/">Volume. Other African ports — Walvis Bay in Namibia, Maputo in Mozambique, Mombasa in Kenya — are also actively pursuing the opportunity.

A potential medium-term shift toward the Cape would have profound consequences for carbon-emissions accounting, fuel consumption, vessel ordering decisions, port Investment/">Investment and the wider economic geography of global trade. It would also reshape the strategic importance of southern Africa relative to the Gulf and the Eastern Mediterranean in global trade architecture.

Sectoral and consumer impact

For UK and European retailers, the impact of the longer transit times has been most visible in lead-time-sensitive segments. Fast fashion, seasonal merchandise, just-in-time electronics and certain food and drink categories that depend on canned air freight have all been affected. Retailers have responded with a mix of inventory expansion, selective air-freight upgrades and price increases. Several large UK and European retailers have explicitly flagged Iran-related Supply/">Supply-chain costs in recent trading updates.

For UK manufacturers reliant on Asian components, the impact has been more diffuse but no less significant. Automotive groups, machinery makers and electronics assemblers have all reported component lead-time extensions, in some cases of two to three weeks. Production scheduling has had to adjust, and corporate treasurers have been managing higher Capital/">Working Capital/">Capital requirements.

For consumers, the visible effect has so far been modest. Headline retail prices have not moved materially in response to higher freight rates, in part because freight is only one component of total landed cost. Sustained elevated freight rates over many quarters could feed through more meaningfully, particularly if combined with continued energy-driven Inflation/">Inflation. UK and European Inflation/">Inflation forecasters are watching freight metrics closely as a leading indicator.

Outlook and risks

The path of the Iran war remains the single most important variable for global shipping in the months ahead. A negotiated de-escalation that allows the Strait of Hormuz to reopen and reduces the risk profile of the Red Sea would, over time, support a return of container services to the Suez route. The pace of any such return would depend on insurance markets, on the credibility of any settlement and on the willingness of carriers to commit Assets/">Assets to a route that has already failed twice in 24 months.

If, on the other hand, the conflict widens or persists, the Cape route is likely to remain the de-facto main highway for Asia-Europe container trade through 2026 and into 2027. Carriers, freight forwarders, port operators and shippers will continue to invest in operational adaptations, and the broader shape of global logistics will tilt further away from the Eastern Mediterranean and toward southern Africa and the Indian Ocean rim.

Either way, the period since early 2026 will probably be remembered as a moment in which an old assumption — that the Suez Canal is a reliable backbone of east-west trade — was challenged in a sustained way for the first time in a generation. The implications of that challenge will be playing out in shipping markets, port Investment/">Investment decisions and corporate Supply/">Supply-chain strategies for years to come.
