No-Arbitrage Constraint

Constraint

The no-arbitrage constraint, fundamental to derivative pricing, posits that in efficient markets, identical cash flows must have identical prices; any deviation creates an arbitrage opportunity exploited until the mispricing vanishes. Within cryptocurrency markets, this principle extends to cross-exchange discrepancies and synthetic asset valuations, demanding consistent pricing across platforms and representations. Its application relies on the assumption of rational actors and frictionless markets, conditions rarely perfectly met, yet serving as a crucial benchmark for evaluating fair value.
