What is cryptocurrency arbitrage?

Crypto arbitrage is the practice of buying a digital asset on one exchange at a lower price and selling it on another for a higher price. The price gap between the two platforms is known as the spread, and capturing it is where the potential profit lies.

Because cryptocurrencies trade across a wide range of platforms globally, including centralised exchanges like BTC Markets and decentralised ones, slight price differences can appear, especially during periods of high volatility or varying liquidity levels.

These imbalances are often short-lived, requiring quick decision-making and an understanding of the risks involved.

Common types of arbitrage in crypto

There are several forms of arbitrage used in the crypto space, each with its own complexity:

Cross-exchange arbitrage

Also known as spatial arbitrage, this involves buying on one exchange and selling on another. For example, if Bitcoin is trading at AU$120,000 on one platform and AU$121,000 on another, the trader may capture the difference, provided fees and transfer times don’t outweigh the gain.

Triangular arbitrage

This strategy involves moving through three different trading pairs, typically within the same exchange, to profit from pricing inefficiencies. For example: BTC → ETH → USDT → BTC. This approach requires high accuracy and minimal slippage.

DEX arbitrage

Decentralised exchanges (DEXs) often have different liquidity profiles compared to centralised platforms. Traders look for gaps between two DEXs or between a DEX and a CEX to capitalise on price discrepancies.

Statistical arbitrage

Institutional or algorithmic traders may use statistical models and bots to identify and act on small pricing anomalies across multiple platforms. These strategies rely on speed and historical data patterns.

Risks of crypto arbitrage

While arbitrage may appear straightforward, real-world conditions introduce several challenges:

• Volatility: Prices can shift within seconds, making spreads disappear quickly.
• Liquidity: Some platforms may not have enough volume to execute large trades at your desired price.
• Fees: Trading fees, withdrawal charges, and blockchain gas fees can significantly reduce or erase gains.
• Timing delays: Moving assets between exchanges takes time. Network congestion or verification delays can close the arbitrage window.
• Regulatory restrictions: Capital controls in some countries may limit cross-border transfers.
• Platform risk: Exchange outages, downtime, or technical issues can interrupt trades.

Understanding these risks is essential before attempting any form of arbitrage trading.

Notable example: The Kimchi premium

A well-known case of crypto arbitrage occurred during the “Kimchi premium” in South Korea, where Bitcoin traded at a consistently higher price compared to other markets. However, due to capital controls and regulatory restrictions, taking advantage of the spread was difficult, and, in some cases, not legally permissible.

Similarly, during the 2017 bull market, price gaps between global exchanges appeared more frequently. These opportunities were quickly absorbed by experienced traders and bots, highlighting the fast-moving and competitive nature of arbitrage.
