(JUBA) – A weak currency in Africa is more than a technical issue for financial markets. It has direct effects on prices, household income, business costs, and government capacity. Across the continent, currency weakness often increases inflation, deepens poverty, discourages investment, and limits the ability of states to manage economic shocks. These pressures were clearly visible in 2025 as several African currencies recorded sharp declines with wide economic consequences.
During the year, movements in foreign exchange markets revealed deeper structural challenges in many economies. According to the World Bank, the South Sudanese pound and the Ethiopian birr were among the worst performing currencies in 2025, each losing more than 10 percent of their value. These declines were not isolated market events but signs of underlying weaknesses that continue to affect parts of Africa.
South Sudan provides a clear example of how heavy dependence on a single export can weaken a currency. More than 90 percent of the country’s foreign currency earnings come from oil exports. This narrow base leaves the economy highly exposed to external shocks that are outside domestic control. When conditions change along the export chain, the effects are quickly felt across the entire economy.
In 2025, South Sudan’s main oil export route through Sudan faced serious disruption due to conflict in the neighbouring country. Damage to the pipeline leading to Port Sudan reduced oil exports and sharply cut foreign currency inflows. As a result, the South Sudanese pound came under strong pressure and lost value rapidly.
The fall in the currency did not cause the crisis on its own, but it made the situation worse. With fewer dollars entering the economy, imports became more expensive and prices rose across key sectors. Inflation, which stood at 2.4 percent in 2023, climbed to 107.9 percent by September 2025, according to Finance in Africa. This sharp rise reduced purchasing power for households and increased operating costs for businesses.
For companies in South Sudan, currency weakness affects daily operations. Imported fuel, machinery, food, and construction materials become more costly when the pound loses value. Even when prices are quoted in South Sudanese pounds, suppliers often adjust them based on the exchange rate. At the current real market rate in December 2025, one United States dollar equals 7,100 South Sudanese pounds, a level that highlights how far the local currency has fallen.
Ethiopia faced a different but related challenge. The Ethiopian birr became the third weakest currency globally in 2025, after the Argentine peso and the Turkish lira. The government struggled to stabilise the economy while managing a complex debt restructuring process. Currency weakness in this context also reduced investor confidence and increased the cost of imports.
Currency volatility affects both foreign and local investors. International investors are cautious to commit capital when exchange rate losses can quickly wipe out returns. For domestic firms, planning becomes difficult when costs change frequently and unpredictably. Long term investment decisions are delayed, and expansion plans are often put on hold.
For South Sudan, these trends underline the importance of economic diversification. Reducing reliance on oil exports would help stabilise foreign currency earnings and lower exposure to regional shocks. Improvements in transport security, fiscal management, and domestic production could also support greater stability over time.
Below is a simplified illustration of selected African currencies identified among the weakest by the end of 2025, based on international financial trackers.
| Country | Currency | Key Pressure Factor |
|---|---|---|
| South Sudan | South Sudanese pound | Oil export disruption and low inflows |
| Ethiopia | Ethiopian birr | Debt restructuring and macro pressure |
| Sudan | Sudanese pound | Conflict and fiscal instability |
| Zimbabwe | Zimbabwe dollar | Inflation and policy uncertainty |
The experience of 2025 shows that currency weakness in Africa is closely linked to structural economic issues. For South Sudan’s business community, understanding these risks is essential for pricing, investment planning, and long term strategy in a challenging regional environment.
