When the Seas Fracture, the World Fractures With Them

Eighteen of the world’s most important maritime nations have done something they have not done in more than six decades of quiet existence: they have issued a public alarm. The Consultative Shipping Group’s statement, “In defence of free shipping,” is not a routine policy paper. It is a rare admission from the governments that own, manage, or regulate a decisive share of the global fleet that the post-war maritime order is structurally breaking down.

The CSG—Belgium, Canada, Denmark, Finland, France, Germany, Greece, Italy, Japan, South Korea, the Netherlands, Norway, Poland, Portugal, Singapore, Spain, Sweden, and the United Kingdom—represents roughly a fifth of world tonnage by registration and a far larger share by beneficial ownership and control. Greece alone accounts for a substantial slice of global controlled deadweight. These are not peripheral voices. They are the custodians of the system that moves more than 80 percent of world trade. Their message is blunt: the accumulation of wars, chokepoint coercion, shadow fleets, and discriminatory trade measures is no longer a series of shocks. It is a structural shift.

The most corrosive development is the explosive growth of the shadow fleet. Industry estimates place it at more than 1,500 vessels—approaching a fifth of global tanker capacity—operating largely outside conventional insurance, classification, safety, and transparency frameworks. These ships, many aged and poorly maintained, exist to move sanctioned oil from Russia, Iran, and Venezuela. They have created a parallel maritime system: one governed by rules, the other by opacity.

This is not merely an enforcement problem. It is a legitimacy problem. When a significant portion of tanker capacity can ignore the standards that the rest of the industry must meet, the level playing field collapses. Safety and environmental rules become optional for those willing to accept higher risk or higher returns. Insurance markets fragment. Port access becomes politicised. The very idea that commercial shipping is a neutral conduit for trade is eroded.

Simultaneously, strategic waterways are being weaponised. The Strait of Hormuz has become the most visible example, but it is not isolated. The Red Sea, the Black Sea, and the approaches to Somalia have all seen commercial vessels treated as leverage in conflicts that have nothing to do with the ships themselves. UNCLOS rights of innocent and transit passage remain on paper; in practice, passage is increasingly conditional—subject to risk premiums, naval escorts, rerouting, and the threat of drones or missiles. What was once free navigation is becoming negotiated, expensive, and precarious navigation.

For decades the global maritime system rested on a powerful assumption: that commercial vessels could move freely even when states were at odds. That assumption underwrote the extraordinary expansion of seaborne trade after 1945 and again after the end of the Cold War. It is now under sustained pressure from multiple directions at once.

Sanctions regimes, however justified in their political aims, have produced the shadow fleet as an unintended consequence. Unilateral and regional regulatory experiments—whether environmental, security, or protectionist—further fragment the regulatory landscape. When different jurisdictions apply different standards to the same ships, or when access to ports and routes becomes contingent on political alignment, long-term commercial planning becomes nearly impossible. Capital allocation slows. Costs rise. The efficiency gains that made globalisation possible are partially reversed.

The CSG is right to insist that the answer is not simply more rules. The legal architecture already exists: UNCLOS, the IMO’s conventions, the long-established principle of freedom of navigation. The failure is one of consistent application and political will. Uneven enforcement creates the very arbitrage opportunities that the shadow fleet exploits. Multilateral institutions lose authority when powerful states treat them as optional or when enforcement is selective.

Maritime transport is critical infrastructure for food and energy security as much as for manufactured goods. When supply chains fragment, the global economy fragments with them. Higher freight rates, longer transit times, and greater uncertainty translate into higher prices for consumers, pressure on import-dependent economies, and reduced resilience for everyone. Developing countries that rely on efficient seaborne trade for both exports and essential imports are especially exposed.

There is also a strategic dimension. A world in which major powers can credibly threaten to close or condition access to chokepoints is a world of higher military risk and lower economic interdependence. The post-1945 maritime order was designed, in part, to reduce the incentives for exactly this kind of coercion. Its erosion raises the temperature of great-power competition.

Nowhere are these dynamics more punishing than in Africa. The continent sits at the sharp end of chokepoint geopolitics even though it is rarely the primary actor in the conflicts that close or endanger the Strait of Hormuz and the Gulf of Aden, including the Bab el-Mandeb and Red Sea approaches.

The Strait of Hormuz carries roughly one-fifth of global oil and a significant share of LNG and seaborne fertiliser. When conflict has restricted or halted traffic, African importers have absorbed a direct and measurable hit. Between March and August 2026, thirty-two African countries that rely on fossil-fuel imports paid a combined additional $21.9 billion for those imports; the net cost to the continent, after windfalls to a handful of exporters, was still hundreds of millions of dollars. Egypt, South Africa, Morocco, Tanzania, Kenya, Mozambique, and Djibouti ranked among the hardest hit.

Africa as a whole imports the majority of its refined petroleum products while operating refineries at well below global average utilisation. Higher crude prices therefore feed almost immediately into higher pump prices, transport costs, electricity generation costs, and fiscal pressure on governments forced to choose between subsidising fuel or letting inflation accelerate. Currency depreciation compounds the problem: more expensive dollar-denominated fuel imports further weaken local currencies, raising the local-currency cost of every subsequent shipment.

Fertiliser is an equally acute channel. Roughly one-third of global seaborne fertiliser trade normally moves through the Gulf region. East African countries are particularly exposed—Kenya sources about a quarter of its fertiliser imports via these routes; Sudan more than half. Price spikes of 30 percent or more, combined with delayed or cancelled shipments, raise input costs for farmers, reduce application rates, and push food prices higher in economies where households already spend a large share of income on food. The result is a direct threat to food security and rural livelihoods across the Sahel, East Africa, and parts of Southern Africa.

The Gulf of Aden and Red Sea corridor imposes a second, overlapping set of costs. Persistent insecurity—Houthi attacks, the risk of spillover, and rising piracy—has forced the large-scale diversion of vessels around the Cape of Good Hope. Voyages lengthen by a week or more, fuel consumption rises, vessel availability tightens, and insurance and war-risk premiums climb. Freight rates on some routes serving East African ports have increased by as much as 80 percent. Landlocked economies such as Ethiopia, which depend heavily on the Djibouti corridor, and Sudan, whose trade flows overwhelmingly through Port Sudan, feel the effects with particular intensity. Higher shipping costs feed into the landed price of virtually everything—fuel, pharmaceuticals, machinery, wheat, and consumer goods—while also eroding the competitiveness of African exports.

These are not isolated shocks. They arrive on top of earlier disruptions: COVID-era supply-chain strains, the Ukraine war’s effect on grain and fertiliser, and previous Red Sea insecurity. Growth forecasts have been revised downward; inflation and currency pressures have intensified; fiscal space for social spending has narrowed. Oil exporters such as Nigeria and Angola can record temporary revenue gains, yet even they often re-import refined products at elevated global prices and remain exposed to the broader inflationary and logistical fallout. For the large majority of African economies that are net energy and fertiliser importers, the net effect is unambiguously negative: slower growth, higher living costs, and greater food insecurity.

In short, when the maritime rules that once treated commercial shipping as a neutral conduit break down, African countries pay a disproportionate price for conflicts they did not start and over which they exercise little control.

The CSG’s prescription is measured: greater cooperation among maritime nations, consistent enforcement across jurisdictions, better information exchange, and renewed political backing for the IMO and the UNCLOS framework. These are necessary but not sufficient.

First, enforcement against the shadow fleet must become more coordinated and less easily gamed. That means tighter port-state control, more aggressive use of existing tools against vessels that turn off AIS or operate without proper insurance, and closing the remaining loopholes in ownership and flag transparency. Second, major trading powers must resist the temptation to turn shipping regulation into an instrument of industrial policy or geopolitical leverage. Discriminatory measures that fragment markets ultimately raise costs for everyone, including the countries that impose them. Third, the principle that commercial shipping is not a legitimate target in conflicts must be reasserted—through diplomacy, through deterrence, and, when necessary, through collective defence of navigation rights.

For Africa the stakes are existential. The continent needs both immediate mitigation—strategic reserves, regional refining capacity, diversified fertiliser sources, and more resilient logistics corridors—and a stronger voice in the defence of the open maritime order. Without predictable access to the seas, the development gains of recent decades become far harder to sustain.

None of this will be easy. Sanctions create strong incentives for evasion. Great-power rivalry makes cooperation harder. Domestic political pressures push governments toward unilateralism. Yet the alternative is a slower, more expensive, more dangerous, and more fragmented global trading system—one in which the poorest and most import-dependent regions, including much of Africa, absorb the heaviest costs.

The CSG’s intervention is significant precisely because these countries have historically preferred quiet diplomacy. When the quiet powers of maritime commerce feel compelled to speak publicly, the rest of the world should listen. The seas have always been both a commons and a theatre of power. For a long stretch of modern history, the balance tilted toward the commons. That balance is now shifting. Whether it can be restored will determine not only the future of shipping, but the shape of the global economy itself—and the prospects of the hundreds of millions of Africans whose livelihoods depend on it remaining open.
