Exogenous Variable

Last Updated: January 23, 2026

Exogenous variable is an external factor influencing a system, not affected by the system itself. Crucial in modeling.

Exogenous variable is a factor originating outside a given model or system, impacting its behavior or outcome. It’s not influenced by the internal dynamics of the system it affects. In economic or financial models, these variables represent external influences like government policies, global events, or natural disasters. Their value is determined outside the model, yet they can significantly shape outcomes within it. Understanding exogenous variables is crucial for accurate predictions and robust modeling. They provide context and help isolate the impact of internal variables, enhancing strategic planning and decision-making in complex systems like crypto/fiat exchanges.
