Simultaneous Equation Models

Definition

Simultaneous equation models represent a statistical framework where multiple endogenous variables are determined jointly by a system of interdependent relationships. In the context of cryptocurrency derivatives and options trading, these systems account for the feedback loops between spot market prices, implied volatility surfaces, and funding rates. By estimating equations that reflect these concurrent interactions, market participants identify structural dependencies that single-equation regressions fail to capture. This approach provides a robust mechanism for parsing complex causal links within high-frequency digital asset environments.
