What the ZF Score Is

The ZF score is a calibrated probability of sovereign crisis onset within a three-year forward horizon, expressed as a continuous value between 0 and 1. Higher values indicate greater structural fragility.

It is not a credit rating. It is not a narrative assessment. It is a forward-looking signal produced by a validated probabilistic 模型 trained on past structural deterioration and tested on future unseen outcomes.

Crisis definition: IMF emergency financing program initiation or sovereign default event, as recorded in the IMF MONA database and supplementary default event databases.

Every ZF score is decomposable into its nine F-family contributions -- identifying which stress dimension is the primary driver at any point in time.
