Implied Correlation Smiles

Definition

Implied correlation smiles represent the non-linear relationship observed between the implied correlations of assets within a basket or index and the strike prices of their corresponding options. Market participants identify these patterns when option pricing models, which typically assume a constant correlation coefficient, fail to align with the actual premiums demanded for specific volatility structures in crypto derivatives. These smiles signify that traders price in higher correlations for tail-risk events, causing the cost of protection to rise as strike levels deviate from the at-the-money forward price.
