Product tanker carrying Russian naphtha reroutes around Africa as Red Sea threats squeeze energy flows
A Panama-flagged tanker hauling Russian naphtha abandoned a transit through the Bab el‑Mandeb strait in late July and instead sailed around Africa, according to shipping data and trade sources. The costly detour shows how Red Sea security fears are reshaping global energy routes and adding pressure to the already complex trade in Russian oil products.
The decision by a single tanker to turn away from the Bab el‑Mandeb and trace the long arc around Africa is a small move on a map that speaks to a much bigger anxiety. A Panama-flagged product tanker carrying Russian naphtha tried to pass through the strait in the final week of July before reversing course and opting for the Cape of Good Hope instead, according to shipping data and trade sources cited by international market-watchers.
The Bab el‑Mandeb is the narrow southern gate to the Red Sea, linking the Indian Ocean with the Suez Canal and, beyond it, Europe and the Mediterranean. Over the past year, it has become a zone of heightened tension, with attacks and threats against commercial shipping raising the risk calculus for owners, charterers, and insurers. That a vessel carrying Russian cargo chose to abandon the shortcut and accept weeks of additional sailing time and fuel costs underlines how those security concerns are now biting into real trade flows.
For the crew of a tanker contemplating the Bab el‑Mandeb today, the question is not just about currents and traffic density, but about who controls the coastline and what weapons they can bring to bear. Missiles, drones, and fast boats operated by regional actors have turned transit through the strait into a bet on political and military developments far beyond any captain’s control. Taking the long way around Africa is, in effect, buying insurance in the form of distance from those threats.
Operationally, such diversions impose tangible costs. Rerouting a tanker around the Cape of Good Hope adds thousands of nautical miles to a voyage, increases bunker fuel consumption, ties up the vessel for longer, and may require adjustments to delivery schedules and pricing. For cargoes of refined products like naphtha, used as a petrochemical feedstock and blending component, timing can matter for downstream plants and traders banking on just-in-time supply.
The fact that the cargo in question was Russian adds another layer. Since the invasion of Ukraine, Western sanctions and price caps have forced Moscow’s oil exports to seek more distant buyers, often in Asia, using a shadow fleet and complex routing to avoid regulatory tripwires. Security uncertainty in key chokepoints compounds those challenges, making an already convoluted logistics puzzle more expensive and less predictable.
Strategically, each ship that chooses the Cape over the Suez corridor chips away at the efficiency of the global oil and products trade. If enough tankers and container ships follow that pattern, it can tighten effective supply, support higher freight rates, and ultimately feed through to consumer prices. For states that depend on Suez and Bab el‑Mandeb trade – from Egypt to Gulf exporters to European importers – this is a creeping risk that disrupts revenue and planning even without a formal blockade.
A concise way to frame it is this: chokepoints do not have to close to matter – they only need to be dangerous enough that prudent shipowners quietly redraw their routes. Once that happens, the economic map shifts even if the geography does not.
The next developments to watch are whether more tankers carrying Russian or other sensitive cargoes show similar course changes in ship-tracking data, and how insurers adjust premiums for Red Sea passages versus Cape routes. Any coordinated naval moves by regional or extra-regional powers to escort shipping, along with statements from major trading houses about preferred routes, will indicate whether the Bab el‑Mandeb is sliding from being a calculated risk to, for many operators, a route of last resort.
