Arbitrage
Pronunciation: AR-bih-trahzh
Also known as: Price Arbitrage, Market Arbitrage
Definition
Arbitrage is a trading strategy that seeks to profit from a price difference for the same or economically equivalent asset across markets, instruments, venues, or settlement paths. It is often described as low-risk, but real execution involves timing, fees, inventory, funding, transfer, counterparty, blockchain, and settlement risks. Arbitrage attempts to capture price differences across related markets.
Overview
Meaning and scope
Arbitrage is a trading strategy that seeks to profit from a price difference for the same or economically equivalent asset across markets, instruments, venues, or settlement paths. It is often described as low-risk, but real execution involves timing, fees, inventory, funding, transfer, counterparty, blockchain, and settlement risks.
How it works
It is closely connected with Spread , Spot Price , and Liquidity Fragmentation , but these terms answer different questions about price, capacity, execution, or financial resilience. Operationally, traders may buy where an asset is cheaper and sell where it is more expensive, or construct offsetting positions that capture a basis or pricing inconsistency.
Operational checks and limits
Arbitrage attempts to capture price differences across related markets. In practice it is limited by trading fees, settlement delay, liquidity, borrowing and counterparty risk.
Practical example
A trader sees a stablecoin at $0.997 on one venue and $1.001 on another but evaluates withdrawal costs before acting.
Distinctions
Arbitrage exploits relative prices; ordinary liquidity provision earns fees or spread under a different risk profile.
How to evaluate it
A financial metric becomes useful only when its observation method, time interval, and unit are disclosed; for Arbitrage, record the source venue or account, relevant execution or accrual window, conversion assumptions, and whether fees are included. When evaluating Arbitrage, a business treasury should reconcile the reported figure to actual fills and balances rather than use a single screen value as both pricing evidence and a settlement record.
Operational edge cases
A price difference becomes a realizable opportunity only after execution costs, network fees, transfer limits and available liquidity. Market prices can converge before either trade settles, leaving the trader exposed on one venue. On-chain opportunities can also face transaction ordering, slippage and smart-contract risk. A merchant’s conversion policy should not assume that arbitrage immediately eliminates every quoted discrepancy. Related concepts: Spread; Spot Price; Liquidity Fragmentation.
Example

Comparison
Arbitrage exploits relative prices; ordinary liquidity provision earns fees or spread under a different risk profile.
Key Takeaway
Gross price differences are not risk-free profits.
