A weak currency, in which a country’s currency loses value relative to international currencies, frequently does more harm than good. This, unfortunately, seems to be the case for several African countries.
- Devalued currencies often harm households, businesses, and governments.
- For example, Nigeria faces challenges from its volatile naira, impacting inflation, prices, and economic stability.
- Households and small enterprises are particularly vulnerable to economic pressures brought on by currency devaluation.
- Weaker currencies render foreign debt repayment costlier, limiting state budgets and investments.
While some devaluation benefits exporters, persistent weakening poses significant issues for households, businesses, and governments.
In the last few months, Nigeria’s economy has demonstrated the challenges associated with a volatile currency.

Nigeria’s inflation fell for the fifth consecutive month in August 2025, to 20.12% from 21.88% in July.

The naira’s ongoing volatility has put pressure on individuals and companies, despite its government’s efforts to stabilize prices.

A weakened local currency makes it more expensive to repay loans, putting pressure on state budgets and limiting funding available for social services and infrastructure.
Foreign investors frequently avoid nations with fluctuating currencies out of fear of capital loss.
This causes foreign exchange shortages, which further weaken the currency, resulting in a vicious cycle.
In a nutshell, a weaker currency increases economic volatility and discourages long-term trade and investment.
Businesses struggle to plan when costs shift unpredictably.
A weak currency has long-term implications that are costly, including increasing inflation, reduced purchasing power, increased debt burdens, and societal pressure.
