On March 3, 2026, the Joint War Committee of the Lloyd's Market Association issued circular JWLA-033, adding Bahrain, Djibouti, Kuwait, Oman, Qatar and expanded Indian Ocean zones to its Listed Areas — the insurance industry's official designation of waters too dangerous for standard coverage. Within 24 hours, war-risk premiums for vessels transiting the Persian Gulf had climbed 200 to 300%. For a tanker valued at $100 million, the cost of a single voyage jumped from roughly $200,000 to $1 million. At the peak in mid-March, some premiums reached 2.5% of hull and machinery value per seven-day period — up to eight times pre-conflict levels.
None of this happened near the Copperbelt. And the Copperbelt felt all of it.
The connection is not obvious from a map, which is precisely why it is worth explaining. The DRC and Zambia sit 5,000 kilometres from the Strait of Hormuz. But their copper and cobalt travel to industrial markets in Asia and Europe through maritime corridors that the insurance industry now treats as extensions of a war zone — and that dependency has just been exposed in the most expensive way possible.
Two corridors, two different problems
To understand the vulnerability, the geography needs to be precise. Central Africa's mineral exports historically flow through two distinct southern routes, not one. The eastern corridor runs from the Zambian Copperbelt and the DRC's Lualaba province through Tanzania to Dar es Salaam — a route that then carries cargo northeast through the Indian Ocean toward Asia. This is the path most directly affected by Hormuz-related disruption: vessels heading from Dar es Salaam to China or South Korea transit the western Indian Ocean, where the Lloyd's JWLA-033 circular extended the high-risk designation to zones near Somalia and Pakistan. That expansion did not require ships to enter the Gulf. The insurance industry's risk map simply grew large enough to engulf them. The southern corridor runs through Zimbabwe and Botswana to Durban in South Africa — a different direction entirely, toward the Cape of Good Hope and then north to European and American markets. This route bypasses Hormuz-related war-risk zones more cleanly, but it is long, expensive, and bottlenecked at South Africa's rail and port infrastructure. Neither route is clean. Both are affected — differently and to different degrees — by the March 2026 escalation.
The cost that compounds
The insurance premium surge is the most visible cost, but it is not the only one. Brent crude moved from $81 a barrel on March 3 to $112 on March 12 before easing to around $98 by month's end — a 38% swing in nine days. For landlocked Central African mining operations, every dollar increase in the oil price translates directly into higher diesel costs for trucking fleets, generators, and heavy equipment. The DRC's IMF country report from May 2026 specifically cites "surging oil prices since the onset of the war in the Middle East" as a factor affecting the supplementary 2026 budget and pressuring government finances that are already strained by the M23 conflict in the east. Container availability compounds the problem further. When major shipping lines — Maersk, MSC, CMA CGM, Hapag-Lloyd — suspended or rerouted voyages around the Persian Gulf, vessels were repositioned and schedules disrupted across global networks. Around 10% of the world's container ships were caught in the broader backlog, according to reporting from the period. For a logistics coordinator booking container space from the Copperbelt, the disruption manifested as equipment shortages and cancelled bookings at origin — thousands of kilometres from the conflict.
Why this accelerates the western pivot
The March crisis did not create the argument for the Lobito Corridor. It made it unanswerable. By routing mineral exports westward through Angola to the Atlantic, Central African nations bypass the Indian Ocean entirely. There are no Lloyd's Listed Areas on the route from Lobito to Rotterdam or Baltimore. There is no war-risk surcharge. There is no exposure to whatever the next disruption in the western Indian Ocean turns out to be. This is why the US and EU publicly frame their investments in Lobito through a supply chain security lens, not just a development one. The US DFC's $553 million loan to the Lobito Atlantic Railway consortium is not primarily aid. It is an insurance policy against exactly the scenario that played out in March — the sudden, unanticipated elevation of cost and risk on the routes that currently carry the minerals powering the clean energy transition.
The critical caveat — and it is a significant one — is that the Lobito corridor cannot yet absorb the traffic the argument demands of it. The DRC section between Dilolo and Kolwezi runs at 10 to 15 kilometres per hour on degraded track, using less than 5% of its capacity. The World Bank $500 million loan request for rehabilitation was submitted in October 2025. The Zambian greenfield extension broke ground in February 2026 and will not be complete before the end of the decade. The western corridor is the right answer. It is not yet a functioning one.
The structural lesson
What the Hormuz crisis exposed is not a supply chain problem that can be solved by one infrastructure project, however well-financed. It is a structural dependency problem: Central Africa's mineral exports remain concentrated on routes vulnerable to conflicts the region has no role in and no leverage over. Insurance repricing, oil price shocks, and container shortages are three different transmission mechanisms for the same underlying vulnerability. All three fired simultaneously in March 2026.
The Lobito Corridor, PAPSS's cross-border payment infrastructure, and the mineral processing capacity that would allow more value to stay in the region rather than leave as raw ore — these are not separate development projects. They are three components of the same strategic answer. The Copperbelt's exposure to a chokepoint 5,000 kilometres away is not a geography problem. It is an integration problem. And March 2026 made clear that the cost of not solving it is not theoretical.
