The Economic Impacts of Weak Currencies in Africa

A weak currency can be likened to a house of cards—it may appear stable until the slightest disturbance brings it crashing down. For nations, the ramifications stretch beyond fluctuating exchange rates. A weak currency can undermine economic stability, erode investor confidence, and adversely affect the well-being of a nation’s citizens. Have you ever wondered how essential currency stability is for a thriving economy?

Take Zimbabwe, for instance. In April 2024, the country rolled out a revolutionary new currency known as the ZiG, which was designed to be backed by gold. Central to this initiative was the intention to restore economic stability. Yet, by February 2025, the ZiG had plummeted in value by an astonishing 95% on the unregulated market, despite the central bank’s relentless interventions. It raises a pertinent question: How can a country reclaim lost economic ground when its currency falters so dramatically?

This dire situation highlights the profound complexities that come with adopting alternative currency models without a foundation of robust economic principles. What does it take to build a currency that can withstand the pressures of both local and international markets?

Fast forward to April 2025, and reports from Imara Asset Management—the oldest independent brokerage in Zimbabwe—indicate that the ZiG is on the verge of failure, not merely due to swift devaluation, but rather its rising irrelevance. It’s worth noting that in a span of just 15 years, Zimbabwe has made six attempts to establish a stable indigenous currency, with the ZiG being the most recent.

Introduced just a year ago, the ZiG was fortified by $100 million in foreign exchange reserves and 2.5 tons of gold. Yet, despite this backing, approximately 80% of transactions within the country are still conducted using US dollars, with a minor fraction utilizing the South African rand. It’s a striking dichotomy—how can a new currency thrive when the populace clings to foreign ones for their transactions?

President Emmerson Mnangagwa boldly stated last year that Zimbabwe’s multicurrency system would be phased out by 2030, positioning the ZiG as the sole legal tender. Can a paradigm shift such as this truly reshape a nation’s economic outlook?

When examining the broader implications, many African countries heavily rely on imports for essential commodities, ranging from petroleum to medications and food supplies. Consequently, a depreciating currency translates into soaring import costs, aggravating inflation and stripping away citizens’ purchasing power. Reflecting on this, consider the plight of Nigeria, where continuous inflation struggles—peaking at 23.71% in April 2025—can be traced back to a weak naira, which raises living expenses relentlessly.

This leads us to a pressing issue: what can these countries do to shield themselves from the repercussions of weak currencies? With the world’s economic landscape constantly evolving, these are questions that require urgent discourse.

In light of the current climate, here’s a snapshot of the 10 African nations grappling with the weakest currencies in May 2025, according to the Forbes currency converter. Keep in mind that this data is ever-changing, with economic forces at play that can swiftly alter standings.

As we delve into the specifics, it’s notable that currencies in Guinea, Burundi, and the Democratic Republic of the Congo have seen their values dip last month. Conversely, Uganda, Malawi, Tanzania, Nigeria, and Rwanda have experienced slight increases in value. What factors might have contributed to these fluctuations? A deeper understanding could serve as a roadmap for other nations navigating similar turmoil.
