Expiration Friction

Friction

Expiration friction, within cryptocurrency derivatives, represents the impediment to seamless rollover of expiring contracts, manifesting as price discrepancies between the expiring series and the next available. This phenomenon arises from the imperfect substitutability of contracts due to factors like differing liquidity, open interest, and the cost of carrying a position forward. Consequently, traders experience a cost—the friction—when attempting to maintain exposure through expiration, impacting optimal hedging strategies and potentially leading to suboptimal execution.
