imbabwe has secured a place among Africa’s 15 largest economies, with gross domestic product (GDP) projected to reach $65.92 billion in 2026, supported by stronger mining activity, agricultural recovery and higher gold export earnings despite longstanding currency and debt challenges.
- Zimbabwe is projected to be Africa’s 14th largest economy in 2026 with a GDP of $65.92 billion, supported by agriculture and mining recovery.
- Zimbabwe’s economic growth is forecast at 5% for 2026, lower than Tanzania’s projected 5.9%, due in part to different monetary policies.
- Zimbabwe continues to face persistent challenges from high inflation, currency volatility, and significant debt arrears, restricting access to international finance.
- Tanzania, in contrast, has strengthened the use of its national currency, seen stronger GDP growth, and diversified through major energy and infrastructure investments.
According to the International Monetary Fund’s (IMF) October 2026 World Economic Outlook, Zimbabwe ranks 14th among Africa’s largest economies, ahead of Cameroon at $64.81 billion and Tunisia at $62.74 billion.
The latest position marks an improvement from earlier IMF estimates, which placed the country 17th in 2025 with GDP of $51.22 billion. In April 2026, the Fund ranked it 16th at $56.71 billion, before revising its projections in October.
The southern African economy is expected to grow by 5% in 2026, following an estimated 8.3% expansion in 2025, supported by favourable gold prices, recovering agricultural production and remittance inflows.
Despite these gains, Zimbabwe trails Tanzania, whose economy is projected at $96.18 billion, $30.26 billion larger, with growth forecast at 5.9% in 2026.
The two countries also differ in currency policy, with Zimbabwe heavily reliant on the US dollar while Tanzania has strengthened the use of its national currency in domestic transactions.
Zimbabwe's recovery highlights currency challenges
Years of high inflation, currency depreciation and repeated monetary reforms have weakened confidence in Zimbabwe's local currency, driving widespread use of the US dollar.
In April 2024, the government introduced the Zimbabwe Gold (ZiG) to replace its previous currency and restore monetary stability.
Despite the reform, the US dollar remains dominant, accounting for about two-thirds of payments by value in the national payment system, according to the IMF's May 2026 assessment.
The transition also affected major businesses, including Econet Wireless Zimbabwe, founded by billionaire Strive Masiyiwa, which adjusted its payment systems to accommodate the new currency.
While dollarisation has helped households and businesses protect their finances against depreciation, it has reduced the central bank's control over monetary policy.
The authorities have since tightened monetary policy to stabilise prices and exchange rates. Annual ZiG inflation stood at 2.9% in August 2026 before rising to 3.7% in September, according to the Zimbabwe National Statistics Agency.
In its August assessment, the IMF acknowledged the improvement but urged continued fiscal discipline and reforms to strengthen confidence in the financial system.
However, Zimbabwe's monetary history complicates comparisons of its GDP with those of other African economies.
Nominal GDP expressed in US dollars is influenced by exchange rates and national accounting methods, meaning currency movements can alter international rankings without corresponding changes in production.
According to the IMF's October 2026 database, Zimbabwe's national accounts were redenominated following the introduction of the ZiG, making consistent currency measurement essential when comparing figures across different years.
As a result, its projected $65.92 billion GDP reflects economic output valued in US dollars rather than a direct measure of monetary stability or living standards.
Tanzania offers a different economic picture
Tanzania, meanwhile, has pursued a different approach to currency management, taking steps to strengthen the use of the Tanzanian shilling in domestic transactions.
In March 2025, the government introduced regulations requiring businesses to price goods and services and accept payments in shillings, subject to specified exceptions.
Alongside these measures, agriculture, construction, mining, tourism and infrastructure investment have supported economic growth.
The country is also pursuing a proposed $42 billion liquefied natural gas project involving international energy companies, although a final investment decision remains pending.
Tanzania's faster projected growth reflects these broader economic activities and investment trends rather than currency policy alone. Both countries remain exposed to exchange rate pressures and external economic risks.
