Exploring the concept of under-valued currency, its historical context, economic impacts, and key considerations for global trade and finance.
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.
An under-valued currency can lead to an improved balance of payments by enhancing the competitiveness of exports.
However, undervaluation can lead to imported inflation as imported goods become more expensive.
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 \( E \) is the exchange rate, \( P_{\text{domestic}} \) is the domestic price level, and \( P_{\text{foreign}} \) is the foreign price level.
It is often challenging to precisely determine if a currency is under-valued due to dynamic and complex global economic factors.
Persistent undervaluation can lead to international tensions and retaliatory trade measures.
