This chart tracks four structural metrics of intra-African trade from 2020 to 2024. The dotted grey line shows the full 2000–2024 context so you can see where the recent period sits historically.

Network Density measures what fraction of all possible bilateral trade links (54×53 = 2,862) actually exist. A value of 0.13 means 13% of all possible country pairs are actively trading.

Active Trade Links is the raw count of bilateral pairs with a Trade Intensity Index above 1 — meaning they trade more intensely than their global share would predict.

Reciprocity measures what share of trade relationships go both ways. A value of 0.58 means 58% of trade links are mutual — when A exports to B, B also exports to A.

Clustering Coefficient captures trade triangle formation — if A trades with B and A trades with C, do B and C also trade with each other? High clustering indicates supply chain integration rather than hub-and-spoke patterns.

The red vertical line marks January 2021 when AfCFTA entered into force. Every metric shows a downward trend from 2021 to 2024, with 2022 showing a brief recovery driven by the commodity price spike before declining again.

This chart combines two views: the bars show the raw count of active trade links (right axis) and the red line shows network density (left axis) across the full 2000–2024 period.

Three major structural events shaped African trade network evolution:

Commodity Boom (2000–2010): Rising commodity prices drove Africa's largest exporters — Nigeria, Angola, Algeria, Libya — into more bilateral relationships. Network density climbed from 0.13 to 0.15.

Commodity Price Crash (2015): When oil and mineral prices collapsed, commodity-dependent African exporters sharply reduced their trade footprint. Network density fell to its lowest point — 0.1157 — and active links dropped from 424 to 331.

COVID-19 (2020): The pandemic disrupted supply chains and reduced intra-African trade links further, though the impact was smaller than the commodity crash.

AfCFTA (2021–2024): The highlighted teal bars show the post-AfCFTA period. Despite the trade agreement, density has not recovered to pre-2015 levels and has continued declining since 2021.

This force-directed network shows which African countries trade most intensely with each other in 2024.

Nodes (circles) represent countries. Size reflects total intra-African export value — larger circles are bigger exporters within Africa. Colour indicates which Louvain-detected trade community the country belongs to.

Edges (lines) connect country pairs with a Trade Intensity Index above 1, meaning they trade more intensely than their global market shares would predict. Thicker lines indicate stronger trade intensity.

Position is determined by trade gravity — countries that trade heavily with each other are pulled physically closer in the layout. Countries on the edges of the graph are structurally peripheral.

Six trade communities emerged:

• ■ Southern Africa (SADC) — South Africa, Botswana, Namibia, Zimbabwe anchor the densest cluster
• ■ East Africa — Kenya, Tanzania, Uganda, Rwanda form a tightly integrated corridor
• ■ West + North Africa — Morocco, Nigeria, Côte d'Ivoire, Egypt loosely connected across a large arc
• ■ Central Africa — Gabon, Congo Republic, Equatorial Guinea — resource-linked cluster
• ■ North Africa Periphery — Algeria, Tunisia, Libya — connected more to global markets than to sub-Saharan Africa
• ■ West Coast mini-cluster — Guinea and Ghana with distinct bilateral intensity

This bump chart tracks the structural centrality rankings of Africa's top 8 trade hubs from 2000 to 2024 at benchmark intervals.

Lower rank = more structurally central. Rank 1 means that country is the most important hub in the intra-African trade network based on Eigenvector Centrality — a measure that gives higher scores to countries whose trading partners are themselves important hubs.

The 2010 structural shift (marked by the vertical dashed line) is the most dramatic feature of this chart. Before 2010, Kenya, Morocco, and Côte d'Ivoire dominated the rankings. After 2010, Botswana, Namibia, and South Africa locked in the top positions and have not moved since.

This reflects the deepening of the SADC customs union — Botswana and Namibia trade intensely with virtually every Southern African country simultaneously, giving them extraordinarily high network centrality despite being relatively small economies by GDP.

The implication for AfCFTA is significant: if the agreement is to create a truly pan-African integrated market, it needs to reduce the dominance of the SADC cluster and create meaningful cross-regional connections between East, West, and Southern Africa.
