South Atlantic

Regional Risk Context

The South Atlantic connects the major commodity-exporting economies of West Africa and South America with global markets, carrying crude oil, iron ore, soybeans, coal, and containerized goods. The region's ports serve as export gateways for regional commodities and import terminals for manufactured goods and energy products. The South Atlantic's risk profile is dominated by two distinct threat clusters: Gulf of Guinea piracy off the West African coast, and the increasing strategic importance of the Cape of Good Hope routing as an alternative to the Red Sea corridor.

The Gulf of Guinea has surpassed the Gulf of Aden as the world's most active piracy zone, accounting for the majority of global piracy incidents and the vast majority of crew kidnappings. Unlike Somali piracy, which focused on vessel hijacking and ransom, Gulf of Guinea pirates typically conduct short-duration attacks aimed at kidnapping crew members for ransom, stealing cargo and valuables, or conducting oil cargo theft from tankers. The Nigerian Maritime Administration and Safety Agency (NIMASA) has deployed the Deep Blue Project to combat piracy, but the geographic scope of the threat exceeds the capacity of any single national response.

The diversion of container traffic around the Cape of Good Hope due to Red Sea security threats has increased traffic density in the South Atlantic and along the South African coast, creating new congestion at bunkering ports and repair facilities. Weather conditions in the South Atlantic are generally more benign than the North Atlantic, but the Roaring Forties latitude band (40-50 degrees south) produces severe weather that affects Cape routing vessels.
