Financial risk refers to the probability that actual returns will differ from expected returns on an investment. The main types of financial risk are credit risk, liquidity risk, interest rate risk, market risk, and operational risk. Credit risk arises from the possibility of default or decline in the credit quality of counterparties. Liquidity risk stems from the inability to raise funds or sell assets quickly with minimal loss of value. Interest rate risk is the sensitivity of assets and liabilities to changes in interest rates.
