Negative Convexity

Definition

Negative convexity refers to a financial phenomenon where an instrument’s price sensitivity accelerates inversely to price movements, causing the duration to shorten as yields rise. In cryptocurrency derivatives, this behavior frequently emerges in products like inverse swaps or options where the delta exposure shifts disadvantageously during extreme market volatility. Traders encounter this state when the second derivative of the price with respect to the underlying asset is negative, leading to diminishing returns on gains and compounding losses during rapid directional shifts.
