Cross-Exchange Price Parity
Cross-exchange price parity is the state where the price of an asset is identical across multiple trading platforms after accounting for transaction costs and transfer times. Arbitrageurs constantly monitor these exchanges to identify deviations from parity and execute trades to bring prices back into alignment.
This mechanism is essential for efficient price discovery in decentralized finance. When parity is achieved, it indicates that the market is functioning effectively and that information is being incorporated into prices globally.
Persistent deviations from parity often suggest barriers to entry, such as capital controls or high withdrawal fees. Achieving parity is the primary goal of professional arbitrage operations.
