In insurance terminology, the cause of a loss is known as a peril . A peril is the specific event or cause that results in damage, injury, or financial loss. Common examples of perils include fire, theft, accident, illness, disability, or death . In life and health insurance, the insured event—such as death in life insurance or sickness and accidental injury in health insurance—is considered the peril that triggers the insurer’s obligation to pay benefits under the policy. Insurance policies are designed to provide financial protection against losses that result from covered perils.

It is important to distinguish a peril from other related insurance concepts. A hazard is a condition or situation that increases the likelihood or severity of a loss caused by a peril. Hazards are typically categorized as physical hazards (such as icy roads or faulty wiring), moral hazards (dishonesty or fraudulent behavior), and morale hazards (carelessness because of insurance coverage). An exposure refers to the possibility of loss, while risk refers to the uncertainty regarding the occurrence of a loss. Therefore, the term that specifically describes the direct cause of a loss is a peril .
