Cryptocurrency arbitrage exploits price differences that arise when identical assets trade at different values across venues, a condition that reflects fragmented liquidity and varied local demand. Alexander W. Schoar at MIT Sloan documents that latency, transfer costs, and platform-specific constraints prevent immediate alignment of prices, creating exploitable spreads for market participants. The phenomenon matters because arbitrage activity links isolated markets, contributes to price discovery, and can reduce volatility when frictions are surmountable.
Mechanics of cross-exchange arbitrage
Execution typically involves identifying a price gap, acquiring the asset on the cheaper exchange, transferring or simultaneously executing offsetting positions, and realizing the spread after accounting for fees and settlement risk. Arvind Narayanan at Princeton University highlights that on-chain settlement times and withdrawal limits often force reliance on pre-funded accounts or rapid cross-exchange trading, which increases capital requirements and operational complexity. Philip Gradwell at Chainalysis reports episodes of pronounced regional premiums such as the Kimchi premium in South Korea, where local demand, regulatory factors, and fiat on-ramps created persistent differentials that attracted arbitrageurs despite added frictions.
Constraints and consequences
Costs and risks that blunt arbitrage include network congestion, variable trading fees, price slippage during execution, counterparty trust, and regulatory restrictions that limit capital movement. Research findings by Alexander W. Schoar indicate that these limits to arbitrage can allow price dispersion to persist and enable opportunities for manipulation when oversight is weak. From a systemic perspective, Bank for International Settlements analysis notes that such frictions can amplify market segmentation and complicate the assessment of global market liquidity.
Human, territorial, and environmental dimensions
Local cultural preferences, capital controls, and payment rails shape where and when price differences appear, producing distinct patterns across regions and time zones. Traders in jurisdictions with constrained fiat exchange access have historically faced both higher barriers and greater incentives to perform arbitrage, embedding socio-economic factors into price formation. The Cambridge Centre for Alternative Finance at the University of Cambridge documents that the choice of settlement layer and its energy footprint also influence the economics of transferring assets for arbitrage, linking environmental considerations to operational decisions. Overall, crypto arbitrage reflects a complex interaction of technology, regulation, and human behavior that differentiates it from classical financial market arbitrage.
