Currency risk is the academic concept and research area focused on the potential for financial loss or gain resulting from fluctuations in the exchange rates between different currencies. This field investigates the causes and effects of foreign exchange rate volatility, the exposure of entities (such as corporations, investors, or governments) to such volatility, and the methods for quantifying, mitigating, and managing these exposures through strategies and financial instruments. Its significance lies in understanding and managing the financial impact of international transactions, investments, and capital flows in a globalized economic environment.
