Summary of SACU in Global Value Chains: Measuring GVC Integration, Position, and Performance

Core Content

This report, prepared by Jakob Engel with inputs from Deborah Winkler and Thomas Farole, examines the participation, integration, and performance of the Southern African Customs Union (SACU) countries—Botswana, Lesotho, Namibia, South Africa, and Swaziland—in global value chains (GVCs). It uses the Eora multi-region input-output (MRIO) database and other trade data sources to provide insights into the structure of trade and value-added flows, as well as the challenges and opportunities for GVC integration in the region.

Main Viewpoints

• Globalization and GVCs: The rise of GVCs has transformed global trade and investment. Production processes are now more fragmented and spread across countries, allowing developing economies to integrate into these networks to enhance competitiveness and productivity.

• Importance of Value Added: Understanding domestic value added (DVA) in exports is crucial for assessing a country's role in GVCs. This includes distinguishing between domestic and foreign content in exports, as well as indirect value added (IVA) from imported inputs.

• SACU's Potential: The SACU region has the potential to attract GVC-oriented investment due to its natural resources, labor surplus, and relatively good infrastructure. However, there are challenges such as limited skills, weak market links, and regulatory barriers.

• Data Sources and Methodology: The Eora database is the primary data source, offering a comprehensive and internationally comparable dataset for analyzing GVC participation. It includes 189 countries and 26 sectors per country. The report also compares Eora data with Comtrade and discusses the limitations and uncertainties of the data, particularly for smaller countries.

Key Information

1. Trade Integration and Openness

• Trade Openness: SACU countries have varying levels of trade openness, with Lesotho and Swaziland being among the most trade-dependent globally.
• GDP Share: Trade openness is generally higher for smaller countries, as they have smaller domestic markets. Botswana and Namibia, despite significant mineral exports, are less integrated into global trade compared to their peers.
• South Africa: South Africa has a relatively low degree of trade openness in regional terms but is still more open than many of its peers like China, Brazil, and Peru.

2. Main Traded Sectors

• Botswana: Mining (especially diamonds), vehicles, textiles, beef, and tourism are the main export sectors.
• Lesotho: Clothing and textiles are central to its exports, accounting for 60% of total exports and employing 80% of the manufacturing labor force.
• Namibia: Mining and mineral processing are key sectors, but the country remains relatively minimally integrated into value chains.
• South Africa: A major hub for GVCs, especially in the automobile, mining, finance, and agriculture sectors.
• Swaziland: Relies heavily on South Africa for goods and services inputs, with exports including sugar, forestry, and textiles.

3. GVC Integration and Positioning

• Intermediates in Trade: The share of intermediates in exports and imports is a proxy for GVC integration. SACU countries have shown growth in intermediates, but their integration remains limited.
• Structural Integration: The analysis uses trade networks and centrality measures to assess the position of SACU countries in global trade. South Africa is central, while the other SACU countries are less so.
• Upstreamness and Domestic GVC Length: These indicators help assess the depth of a country's participation in GVCs. South Africa has a higher level of upstreamness and longer domestic GVCs compared to the other SACU countries.

4. Domestic Value Added (DVA) Trends

• Growth of DVA: There has been an overall increase in DVA in SACU exports, particularly in sectors such as textiles, transport, and agriculture.
• Sectoral Growth: The agriculture and food & beverages sectors have shown significant DVA growth, while the hotel and restaurant sector has also seen increases.
• Limitations: The Eora database may have some inaccuracies, especially for smaller countries, due to data imbalances and interpolation methods.

5. GVC Participation and Performance

• GVC Participation Index: South Africa leads in GVC participation, followed by other SACU countries, though the index is not fully reliable for all.
• Drivers of Participation: Forward and backward integration, along with geographical and sectoral factors, influence GVC participation. South Africa is a major hub for both.
• Opportunities and Constraints: While SACU countries have potential, especially in beneficiation of minerals and agricultural products, they face challenges such as skills shortages, weak market links, and limited access to financial services.

Conclusion

The report highlights the growing importance of GVCs in the global economy and the potential for SACU countries to benefit from deeper integration. However, it also underscores the need for improved data quality, sectoral development, and policy support to enhance their participation and performance in GVCs. South Africa is identified as the most integrated and competitive SACU country, while the others face varying degrees of challenges and opportunities.
