Competition in the financial market puts currently new requirements for cost reduction on financial institutions. Available sources of cost reduction are seen i.a. in minimizing legal risks, which can reduce the uncertainty associated with enforcement and interpretation of legal acts, treaties and regulations in the field of contractual obligations. In this regard, banks in the Czech Republic are looking for new ways to reduce costs in the ongoing implementation of Basel II and preparation for implementation of Basel III. The central problem to which attention is focused is to ensure the required level of capital adequacy. This is conditioned i.a. by their risk management system. Capital adequacy may affect credit risk substantially. Besides others, the level of credit risk may be affected to a considerable extent by application of hedging instruments. This paper presents conclusions of the executed comparison of the existing and new private law provisions in the Czech Republic and, based on that, draws new opportunities and difficulties for banks in managing their credit risk and capital adequacy. The focus is only on the hedging instruments that may affect the activities of banks in a significant way.
