Basis Risk in Parametric Models
Basis risk in parametric models occurs when the payout triggered by the insurance contract does not perfectly align with the actual financial loss experienced by the policyholder. Because parametric insurance pays out based on a pre-defined trigger ⎊ like a specific price point ⎊ it may not account for the nuances of the user's specific situation.
For example, a user might suffer a loss due to a protocol bug that does not meet the specific "hack" trigger defined in the contract. This mismatch is a significant limitation of parametric insurance and requires users to carefully understand the terms of their coverage.
It is a fundamental trade-off for the speed and automation that parametric insurance provides.
