Overview
Arbitrage is a trading strategy that involves simultaneously buying and selling the same financial asset or cryptocurrency across different exchanges or liquidity pools to profit from temporary price imbalances. Because the trade involves buying and selling equal amounts of the asset at the same time, the trader (known as an arbitrageur) takes on little to no directional market risk.
Key Characteristics of Arbitrage
- Price Discrepancies: Variations in asset pricing occur naturally across different trading venues due to localized supply and demand imbalances, liquidity depth, or information propagation delays.
- Promoting Market Efficiency: Arbitrageurs play a crucial role in financial ecosystems by rapidly identifying and closing price gaps, helping maintain price consistency across the global market.
Primary Risks and Challenges
Although arbitrage carries low price risk, it involves operational and financial challenges:
- Execution & Latency Risk: The strategy requires near-instantaneous execution. Delays in transaction processing can lead to missed opportunities or unhedged exposure if one side of the trade fails to execute in time.
- Transaction Fees: Buying and selling across multiple venues incurs exchange commissions, withdrawal fees, and blockchain network (gas) fees. High trading costs can quickly eliminate small profit margins.
- Automated Competition: Advanced algorithmic trading bots and MEV (Maximal Extractable Value) searchers constantly scan markets, eliminating price discrepancies within milliseconds and making manual arbitrage increasingly difficult.
