Fork Basis Risk

Definition

Fork basis risk represents the financial exposure incurred by market participants when a blockchain network undergoes a protocol split, resulting in the divergence of an underlying asset into two distinct chains. Traders holding derivative contracts on the primary asset face uncertainty regarding how clearing houses or exchanges determine the settlement price post-fork. This discrepancy between the spot price of the legacy chain and the synthetic valuation of the derivative instrument introduces volatility that standard hedging models often fail to account for effectively.
