Arbitrage
Arbitrage is the practice of profiting from price differences for the same asset across different markets. A trader buys low in one market and sells high in another, capturing the spread. In efficient markets, arbitrage opportunities are small and disappear quickly.

Arbitrage in Practice
A currency trader notices the euro is trading at $1.1000 in New York and $1.1005 in London. They buy euros in New York and simultaneously sell in London, pocketing $0.0005 per euro. On a million-euro trade, that's $500 in nearly risk-free profit. These gaps close within seconds in modern electronic markets.
Why It Matters
Arbitrage plays an important role in keeping markets efficient. When traders exploit price differences, they push prices toward equilibrium across markets. This benefits everyone by ensuring fair, consistent pricing.
For small business owners, arbitrage is less about trading strategies and more about understanding how markets work. Interest rate arbitrage — borrowing at a low rate and earning a higher rate on deposits — is something every business owner should understand when managing cash.
FAQ
Q: Is arbitrage risk-free?
