Rising Trade Tensions Within SACU
Growing trade restrictions within the Southern African Customs Union (SACU) are raising concerns about the future of regional agricultural trade. The Agricultural Business Chamber (Agbiz) has warned that recent export barriers imposed by neighbouring countries could disrupt agricultural flows and weaken the customs union’s core principle of free movement of goods.
Export Restrictions Spark Concern
According to Agbiz Chief Economist Wandile Sihlobo, countries such as Namibia, Botswana, and Mozambique have recently imposed restrictions on South African agricultural exports, particularly vegetables. These measures run counter to SACU’s framework, which is designed to enable seamless trade across member states.
He noted that the essence of a customs union lies in the free movement of goods, adding that such unilateral actions risk undermining the very structure that supports regional trade.
Conflict With Continental Trade Goals
The situation is further complicated by Africa’s broader integration ambitions under the African Continental Free Trade Area (AfCFTA), which aims to eliminate trade barriers across the continent by 2030. Protectionist measures at a regional level could slow progress toward this goal and weaken confidence in multilateral trade agreements.
Protectionism vs Regional Cooperation
While governments are under pressure to strengthen domestic food production, Agbiz maintains that restrictive trade policies are not a sustainable solution. Sihlobo argues that a more effective approach would involve coordinated regional strategies that support production without disrupting trade flows.
He emphasised that restrictions should only be used in specific cases, such as national security concerns or disease outbreaks. However, the recent bans on vegetables, fruit, and poultry products were not linked to such risks, but rather to domestic policy priorities.
Economic Impact on South Africa
South Africa’s agricultural sector is particularly exposed to these disruptions due to its strong trade ties within the region. Approximately 17% of the country’s $15.1 billion agricultural exports in 2025 were destined for SACU markets, a figure that closely rivals exports to the European Union.
When export channels are suddenly restricted, surplus produce floods the domestic market, pushing prices down and increasing volatility. This creates uncertainty for farmers and exporters, ultimately affecting the broader agricultural value chain.
Industry Concerns Grow
Dawee Maree, Head of Agriculture Information and Marketing at First National Bank (FNB), described the situation as deeply concerning. He pointed out that while neighbouring countries may aim to protect their own industries, these actions are counterproductive within a customs union framework.
Such disruptions not only distort markets but also erode trust between trading partners, making long-term planning more difficult for agribusinesses.
Calls for Reform and Dialogue
Agbiz is calling for renewed dialogue among SACU members to ease tensions and restore alignment. Sihlobo stressed the importance of adapting regional agreements to a changing global environment while maintaining cooperation.
He also suggested that countries seeking to expand their agricultural output could benefit from working more closely with South Africa, leveraging its advanced agribusiness systems rather than competing through restrictive measures.
Conclusion
The current trade tensions within SACU highlight the delicate balance between national interests and regional cooperation. While efforts to boost domestic production are understandable, they must be carefully managed to avoid undermining shared economic goals.
Without stronger coordination and commitment to open trade principles, the stability of the customs union—and its role in Africa’s broader trade integration—could face increasing strain.
