Currency risk can take various forms and can be obvious or hidden. Protection, limiting or hedging currency risk involves portfolio diversification of both assets and liabilities in foreign currency, as well as the use of risk minimization techniques. Risk minimization techniques, on which this study was made, are hedging instruments, often encountered on the derivatives market. Hedging instruments include derivative operations as forward, futures, options, and swap. Currency hedging refers to the strategy, which tries to minimize exposure to exchange rate fluctuations, in this way minimizing the uncertainty of foreign currency transactions and printing stability of income, profits and cash flow. This mechanism is extremely important for importers, exporters and any companies whose sales or raw materials are in any way related to items whose prices are denominated in foreign currency.
