Southern Africa’s Integration Paradox: Living in the Shadow of a Giant

By Des H Rikhotso

Few regions on Earth can claim integration arrangements as old, or as tangled, as those of Southern Africa. The Southern African Customs Union (SACU), founded in 1910, is the oldest customs union still in operation anywhere in the world. Layered on top of it is the Southern African Development Community (SADC), a 16-member bloc that coordinates everything from macroeconomic policy to regional security. On paper, this makes Southern Africa a model of economic cooperation. In practice, it is a case study in asymmetry – one dominant economy surrounded by smaller neighbors whose fortunes rise and fall with decisions made in Pretoria.

Two Overlapping Institutions, One Shared Goal

Southern Africa’s economic architecture rests on two pillars that frequently overlap in membership and mandate.

SADC, the broader of the two, brings together 16 member states with the stated aim of deepening socioeconomic cooperation, coordinating macroeconomic policy, and maintaining regional security. Its Free Trade Area was designed to phase out tariffs among member states – a worthy ambition that has delivered real, if incomplete, results. Non-tariff barriers, from cumbersome customs procedures to inconsistent regulatory standards, continue to blunt the bloc’s effectiveness and keep intra-regional trade well below its potential.

SACU, by contrast, is narrower but more binding. It manages a common external tariff and, crucially, pools and redistributes customs revenue among its five members: South Africa, Botswana, Lesotho, Namibia, and Eswatini. For the smaller economies in this group, SACU revenue is not a footnote in the national budget – it is often one of its largest single line items, a dependency that carries real political weight.

Together, these institutions have given Southern Africa a level of formal economic integration that many other developing regions can only envy. Yet formal integration has not translated into balanced growth.

The Elephant in the Room: South Africa’s Economic Dominance

Strip away the institutional architecture, and a simpler story emerges: this is a region built around a single, dominant economy.

A one-sided trade relationship. South Africa is, by a wide margin, the region’s principal exporter of manufactured goods, technical expertise, and professional services. Its neighbors, meanwhile, tend to sell it raw materials and commodities. The result is a persistent and substantial trade surplus for South Africa with its SADC partners – a pattern that critics argue entrenches a center-periphery dynamic reminiscent of colonial-era trade flows, even as it fuels South African corporate growth.

The investment landscape, recast. Walk into a bank, a shopping mall, a mobile phone store, or a mine almost anywhere in the region, and there is a good chance the entity behind it is South African. Firms headquartered in Johannesburg have expanded aggressively across banking, retail, telecommunications, and mining, giving South African capital a level of regional reach that few other African economies can match.

Monetary policy, outsourced. Perhaps the starkest illustration of dependency is the Common Monetary Area (CMA), through which the currencies of Lesotho, Namibia, and Eswatini are pegged one-to-one to the South African rand. This arrangement offers smaller economies monetary stability and low transaction costs with their largest trading partner – but it also means their monetary policy is, in effect, set in Pretoria rather than Maseru, Windhoek, or Mbabane.

An Integration Model Worth Examining – and Rethinking

None of this is to say Southern Africa’s institutions have failed. SACU’s revenue-sharing formula has provided fiscal lifelines to some of the world’s smallest economies. SADC’s Free Trade Area, however incomplete, has lowered barriers that once made cross-border commerce needlessly expensive. And the stability offered by the Common Monetary Area is not nothing in a region where currency volatility can wreck a small economy overnight.

But integration built so heavily around one anchor economy carries structural risk. When South Africa sneezes – as it has repeatedly done amid its own bouts of low growth, power shortages, and policy uncertainty – its smaller neighbors catch cold. A regional model this dependent on a single country’s fortunes is not, by definition, a resilient one.

The question facing Southern Africa’s policymakers is not whether to abandon these arrangements – they are too deeply embedded, and too useful, for that. It is whether the next phase of integration can diversify the region’s sources of growth, investment, and monetary stability, so that “regional cooperation” comes to mean something closer to shared prosperity, and something further from dependency by another name.
