Frictionless Market Fallacy

Market

The Frictionless Market Fallacy, prevalent in cryptocurrency derivatives and options trading, assumes that market prices instantaneously reflect all available information and that trading costs are negligible, leading to perfect price discovery. This assumption disregards the realities of market microstructure, including order book dynamics, latency arbitrage, and the impact of high-frequency trading strategies. Consequently, models built upon this fallacy can significantly underestimate risk and misrepresent the true potential for profit or loss, particularly in volatile crypto markets where liquidity can be fragmented. A more realistic assessment incorporates transaction costs, information asymmetry, and the potential for temporary price dislocations.
