Tanzania’s gold exports to South Africa have risen sharply, reaching about $2.293 billion in 2024, reflecting both strong global prices (around $2,500 per ounce) and pressure to boost foreign exchange earnings amid declining aid flows.
At first glance, the trend appears to conflict with Tanzania’s stated objective of promoting value addition in the mining sector and limiting exports of unprocessed minerals. However, analysts argue that the situation is more complex.
South Africa’s regional role
South Africa serves as a key refining and storage hub within the Southern African Development Community (SADC).
Although South Africa is itself a major gold producer, it hosts established refining infrastructure and secure storage facilities that cater to regional producers, including Tanzania. As a result, much of Tanzania’s gold is exported in unprocessed or semi-processed form for refining, certification, storage, or onward sale to global buyers.
Gold sales to Johannesburg reportedly reached $2.226 billion in 2024, making it one of Tanzania’s dominant export flows.
The value-addition dilemma
Tanzania has long emphasized adding value domestically before exporting minerals. Yet gold refining operates within tightly structured global value chains, where:
- Quality certification standards are internationally regulated
- Refineries are embedded in long-standing global trading networks
- Buyers (including central banks and industrial users) rely on recognised refining hubs
Even gold refined to “99 percent” purity may still be treated in global markets as a preliminary stage of processing rather than a final product.
Analysts suggest that mineral value addition—like diamond cutting or gemstone polishing—often depends on established international “guild” systems and branding structures. Attempts by some countries to bypass these traditional networks have historically faced pricing disadvantages or limited market access.
For example, countries such as Russia and South Africa have at times sought alternatives to traditional European diamond hubs like Amsterdam and Antwerp, though such efforts have proven difficult to sustain.
Comparative advantage and market realities
Economists argue that the principle of comparative advantage still applies in mining and refining. Until refining processes, certification systems, and market access mechanisms are fully harmonised and transparent globally—a prospect seen as unlikely in the near term—regional specialization may remain economically rational.
Efforts to force full localization of mineral value chains through regulation can:
Increase operational costs
Deter investment
Strain public resources if managed inefficiently
Ultimately, refined gold—even when upgraded locally—remains largely a globally traded commodity whose pricing and acceptance depend on international verification systems.
Currency and gold price context
The rise in gold exports coincides with a prolonged global appreciation in gold prices relative to the US dollar. Historically pegged at $35 per troy ounce under the Bretton Woods system, gold now trades near $2,500 per ounce, reinforcing its appeal as a reserve asset and store of value.
For Tanzania, exporting gold to South Africa’s refining and storage ecosystem may therefore represent a pragmatic balance between:
- Securing foreign exchange inflows
- Participating in established global gold markets
- Gradually pursuing domestic value-addition ambitions
The debate reflects a broader tension faced by mineral-rich developing economies: how to maximize domestic beneficiation while remaining competitive within entrenched global commodity networks.
