Traditional risk management, sometimes called "insurance risk management," has focused on "pure risks" (i.e., possible loss by fortuitous or accidental means) but not business risks (i.e., those that may present the possibility of loss or gain). Financial institutions also employ a different type of risk management, which focuses on the effects of financial risks on the organization. For example, interest rate risk is a bank's most important financial risk, and various hedging tools and techniques such as derivatives are used to manage banks' exposure to interest rate volatility.
