Stable exchange rates are essential for international trade because they reduce uncertainty and mitigate financial risk for businesses and investors. When exchange rates are volatile, it becomes difficult for companies to predict the costs of imports or the future value of export earnings, which can discourage international commerce and destabilize investments.1

The International Monetary Fund (IMF) was founded in part to address this by promoting international monetary cooperation and working to stabilize currency exchange rates. By fostering a more predictable environment, stable rates help ensure that global trade flows remain efficient and that the foreign exchange market can function as a reliable basis for the global financial structure.231

Conversely, when exchange rates fluctuate significantly, it increases "exchange rate risk," which can lead to economic instability and complicate long-term planning for both governments and private firms. Consequently, maintaining stability is a key objective for ensuring the health of the global economy and the security of international investments.1
