Adjustment Coefficient

An adjustment coefficient is a mathematical multiplier used in financial derivatives and crypto-asset pricing to normalize or recalibrate variables when underlying conditions change. In the context of options or futures, it is often applied to strike prices or contract sizes during corporate actions or protocol upgrades to ensure that the economic value of the position remains constant.

It serves as a bridge between the original contract terms and the new market reality, preventing windfall gains or losses caused by technical shifts rather than market movement. By applying this coefficient, protocols maintain neutrality in their margin engines and clearing mechanisms.

This ensures that traders are not unfairly liquidated or diluted due to structural adjustments. It is a critical tool for maintaining fairness in decentralized finance and traditional derivative markets alike.
