Exchange rate volatility is unpredictable since there are so many factors that affect the movement of the exchange rates i.e. economic fundamental, monetary policy, fiscal policy, global economy, speculation, domestic and foreign political issues, market psychology, rumors, and technical factors. The exchange rate volatility poses a risk, called foreign exchange risk or currency risk, to business sector, in particular, the importers and exporters or those ones who associate with international businesses.
Although businesses could not control the fluctuation of the exchange rates but they can manage the risk by using proper hedging tools e.g. Forward, Futures, and Options, in order to manage their revenues and costs more efficiently.
