Gold, silver and copper — the world price, and what Tanzania actually gets

How to read this — the spread
Tanzania is a minerals economy. For each metal we plot two lines: the world-market reference price and the domestic buying-centre price a local seller actually receives. The gap between them — the spread — is the royalty, clearing fee and margin taken between the global market and the mine gate. It is published, daily, by the Mining Commission.
The 20% rule — why the state is a structural buyer
Since 1 October 2024 (mining-law amendments under the Finance Act 2024), gold producers and licensed exporters must allocate at least 20% of their gold to the Bank of Tanzania before exporting the rest — bought under the Domestic Gold Purchase Programme (reduced royalty, zero VAT). In June 2025 the BoT signed 20%-of-output agreements with Geita Gold Mining, Shanta, Buckreef and Geita Gold Refinery; reserves reached roughly USD 1.3bn by end-2025. The takeaway for the thesis below: this is a price-insensitive, policy-driven offtake — a steady structural bid rather than a price-chaser — which is one reason gold’s short-term price swings need not move the shilling.

The thesis test — does gold move the shilling?
The shilling ignored gold’s swings
A common claim: strong gold exports support the shilling. Both rebased to 100 at the start of 2026: gold whipsawed ±20%, while the shilling drifted a steady ~7% the other way (USD/TZS up = weaker). If gold drove the currency, the two lines would track — instead the shilling followed its own path.

Why it matters for investors
Gold is Tanzania’s single largest export and a growing Bank of Tanzania reserve asset; copper and silver ride the global industrial and monetary cycle. The world price drives export receipts, hard-currency inflows and reserve values — a macro tailwind when high, a headwind when it turns. The domestic price, and the spread to world, is what determines what stays in the country.
