Definition§
An under-valued currency is one whose exchange rate relative to other currencies is lower than what is necessary for achieving external balance. This situation can bolster a country’s balance of payments on the current account by making its exports cheaper and more competitive internationally while making imports more expensive. This often improves the country’s trade surplus and can potentially make borrowing easier if the market anticipates a rise in the currency’s value.
Historical Context§
Historically, countries have occasionally pursued policies to undervalue their currencies for strategic economic advantages. This has often led to conflicts and competitive devaluations, also known as “currency wars.”
Key Historical Events§
- The Bretton Woods Agreement (1944-1971): This system of fixed exchange rates led to occasional imbalances and necessitated currency interventions.
- Asian Financial Crisis (1997): Many Asian currencies were devalued, causing widespread economic turmoil but eventually leading to improved export competitiveness.
- China’s Currency Policy: Persistent allegations have been made against China for keeping the yuan undervalued to benefit from export-led growth.
Economic Impacts§
Improved Balance of Payments§
An under-valued currency can lead to an improved balance of payments by enhancing the competitiveness of exports.
Inflation and Cost-Push Effects§
However, undervaluation can lead to imported inflation as imported goods become more expensive.
Models and Formulas§
The Purchasing Power Parity (PPP) Model§
PPP suggests that in the long run, exchange rates should move towards rates that equalize the prices of an identical basket of goods in any two countries.
where is the exchange rate, is the domestic price level, and is the foreign price level.

Determining Undervaluation§
It is often challenging to precisely determine if a currency is under-valued due to dynamic and complex global economic factors.
