Risk Fundamentals: Perils, Hazards, and Insurability

Insurance vocabulary is precise, and the exam tests it precisely. A peril is the actual cause of loss — fire, windstorm, theft. The loss is the resulting harm — the burned dwelling. A hazard is any condition that increases the chance or severity of a peril, and hazards come in three flavors: physical hazards are tangible conditions (oily rags in a hot attic, faulty wiring, snow load on a roof), moral hazards involve dishonesty (a willingness to cause or exaggerate loss), and morale hazards involve carelessness or indifference because insurance exists. Getting the taxonomy right is half the battle: in the oily-rags fire, the rags are the physical hazard, fire is the peril, and the destroyed home is the loss. Risk itself is classified along three orthogonal axes. Pure risk offers only two outcomes, loss or no loss, which is why fire, theft, liability, and premature death are insurable — no one can profit from them, so the indemnity principle holds. Speculative risk adds the possibility of gain — investing, gambling, currency movements — and is generally uninsurable. Particular risk affects individuals (one house fire) while fundamental risk sweeps whole populations or economies (war, pandemic, currency devaluation); fundamental risks strain private insurance because losses are not independent. Static versus dynamic completes the trio: static risks recur over time while dynamic risks arise from social and technological change. A foreign currency collapse is the exam's favorite compound example: speculative and fundamental, therefore uninsurable. These ideas connect to how insurance actually works. The law of large numbers lets an insurer predict aggregate losses accurately as the number of independent, similar exposure units grows, which is why insurable risks should be definite, measurable, accidental, non-catastrophic, and spread across a large pool — with premiums that remain economically feasible. Adverse selection — the tendency of the worst risks to seek coverage most eagerly — is the constant enemy, countered by underwriting, waiting periods, and reporting requirements. Finally, the risk management hierarchy maps responses onto a frequency-severity matrix: retain low-frequency low-severity losses, prevent and retain high-frequency low-severity losses, transfer low-frequency high-severity losses to insurance, and avoid high-frequency high-severity exposures entirely.
