Does a Weaker Currency Attract Foreign Investment?
A lower exchange rate can make local assets look cheaper to foreign investors, but instability, inflation and currency risk can outweigh that apparent discount.
The apparent discount
When a host-country currency weakens, a foreign investor may be able to buy the same local asset with fewer dollars or euros. IMF research finds that this wealth effect can support foreign direct investment in some circumstances, particularly for investors from countries whose currencies have appreciated.
That does not mean devaluation automatically creates an investment boom. The purchase price is only one part of an investment whose revenues, costs, taxes and eventual sale may occur over many years.
Why currency risk can cancel the discount
An investor cares about the value of future profits when converted back into the funding currency. If further depreciation is expected, a project that looks cheap today may produce a poor foreign-currency return. Hedging may be costly or unavailable.
A weaker currency can also raise the local cost of imported machinery, fuel and intermediate goods. Inflation, shortages or foreign-currency debt can damage the same company the investor is considering buying.
What long-term investors examine
Foreign direct investment depends on market size and growth, infrastructure, workforce skills, tax and legal rules, political and macroeconomic stability, access to finance, and confidence that profits can be converted and transferred. Institutional quality can matter more than a temporary exchange-rate movement.
UN Trade and Development reports that exchange-rate volatility and policy uncertainty can deter long-horizon infrastructure investment. Investors generally value a credible and usable foreign-exchange system more than an artificially cheap but unpredictable currency.
Different investment flows react differently
A manufacturer building a factory, a company buying an existing business and a portfolio investor purchasing a short-term security do not face the same incentives. Export-oriented projects may benefit from local-currency costs and foreign-currency revenue, while import-dependent projects may be hurt by higher input costs.
Portfolio flows can reverse much faster than direct investment. A currency move accompanied by higher interest rates may attract some short-term capital while discouraging borrowing and real investment. Headline inflows therefore need to be examined by type and duration.
How to assess Ethiopia's experience
Ethiopia's 2024 reform moved the official exchange-rate framework toward market-based price discovery and was paired with broader economic reforms. Its investment effect cannot be judged from the birr's level alone.
Useful evidence includes new projects that reach operation, reinvested earnings, export capacity, access to foreign currency, inflation, repatriation experience and the stability of the regulatory framework. The right conclusion is conditional: a competitive exchange rate can help, but credibility and productive conditions determine whether investors stay.
