Law of One Price

Price

The Law of One Price (LOP) posits that identical assets should trade at the same price globally when expressed in a common currency, assuming no transaction costs or barriers to trade. This theoretical benchmark arises from arbitrage opportunities; deviations from the LOP create incentives for traders to exploit price discrepancies, driving prices toward equilibrium. In cryptocurrency markets, however, the LOP frequently fails due to factors like exchange-specific fees, regulatory fragmentation, and varying liquidity conditions, particularly across decentralized exchanges. Consequently, assessing LOP deviations provides insights into market inefficiencies and potential arbitrage strategies, though execution complexities often limit profitability.
