Tanzania’s stock market capitalisation rose to 10.8% of GDP in 2025.

Higher is better. A higher ratio is better because it means more companies can raise long-term money from investors through the exchange, and savers have more ways to hold a stake in domestic business. The latest figure, for 2025, is 10.8% of GDP, up from 9.2% of GDP a year earlier, a rise of 1.6 percentage points. Since 1999 the ratio has ranged from a low of 1.3% of GDP in January 1999 to its current level, which is the highest in that span.

Why it matters. At 10.8% of GDP, the stock market is still small next to the wider economy, so most Tanzanian firms rely on bank loans or their own earnings to grow. Listed companies have a somewhat wider choice of funding than a decade ago, and investors can share in their profits. The state can also use the exchange to raise money and to sell stakes in public companies.
