What is arbitrage: Definition, Types & Examples in Stock and Crypto Markets

KeyTakeaway

• Stock market arbitrage is frequent in India because to price differ between the NSE and the BSE, as well as between the cash and futures markets.
   
• Crypto arbitrage is appealing because markets operate 24/7 a week, resulting in regular price differences across exchanges.
   
• Risks such as transaction fees, slippage, time delays, and liquidity concerns might decrease or eliminate earnings.
   
• Technology plays an important part; effective arbitrage frequently relies on quick platforms, price monitors, and even automated bots.

Arbitrage is the practice of profiting from price differences of the same asset across different markets. For example, if Bitcoin is trading at ₹25,00,000 on one exchange and ₹25,50,000 on another, buying low and selling high earns you ₹50,000 instantly. To make this simpler to comprehend, consider a short tale. Neha and Rahul, two friends who frequently invest, discovered arbitrage after Rahul noted that gold futures were somewhat higher on the international exchange than on the domestic one. They may secure a tiny profit by purchasing locally and selling abroad.  Neha later discovered comparable differences in bitcoin pricing across exchanges.

In this blog, we will look at what arbitrage is, the many varieties (such as geographical, statistical, and triangular), and how it works in stock markets, foreign exchange, and cryptocurrency. We'll also go over numerical examples to demonstrate how these little variations may translate into significant gains when addressed correctly.

What is Arbitrage?

Arbitrage refers to buying an asset in one market at a lower price and selling it simultaneously in another market at a higher price to earn a risk-free profit.

It is commonly used in:

• Stock markets
• Cryptocurrency exchanges
• Currency trading

Example: Rahul notices that the stock of Company A is priced at ₹520 on NSE and ₹525 on BSE. He buys 100 shares from the NSE and sells them on the BSE. His profit: ₹5 × 100 = ₹500 instantly.

Simple Arbitrage Opportunity in the Stock Market

To better understand how arbitrage profits are calculated, let’s look at a simple before-and-after comparison of a stock trade:
 

As seen above, even a small ₹5 difference per share can translate into quick profits when traded in larger volumes, making arbitrage an efficient low-risk strategy.

Types of Arbitrage

There are multiple ways arbitrage can occur based on the market and price behaviour. Here are the major types:

a) Spatial Arbitrage

Profiting from price differences in two geographical locations or exchanges.

Example: Bitcoin on CoinDCX is ₹25,80,000 and on WazirX it is ₹25,65,000. Buying on WazirX and selling on CoinDCX gives a ₹15,000 profit.

b) Temporal Arbitrage

Takes advantage of price differences over time. For example, in after-hours trading.

c) Statistical Arbitrage

Uses mathematical models and algorithms to detect small price inefficiencies.

d) Merger Arbitrage

Occurs when a company is being acquired. Investors buy shares of the target company expecting a price rise.

Arbitrage in Stock Markets

Stock market arbitrage is common due to the presence of multiple exchanges (e.g., NSE and BSE). Price mismatches occur due to supply-demand imbalance, latency, or inefficiencies.

Types of stock arbitrage include:

• Inter-exchange arbitrage
• Index arbitrage (between Nifty and Sensex derivatives)
• Cash and futures arbitrage

Example: Neha buys Reliance shares at ₹2,350 on NSE and sells them for ₹2,360 on BSE. She trades 200 shares and earns a ₹2,000 profit.

Cash-Future Arbitrage Calculation

Another popular form of stock arbitrage is the cash-futures strategy, where traders buy shares in the cash market and simultaneously sell them in the futures market to lock in a spread. Here’s a quick calculation:
 

This shows how a minor price difference between the cash and futures markets may be used to earn risk-free returns, as long as trades are made quickly.

Arbitrage in Crypto Markets

Crypto arbitrage is a fast-growing trend due to the presence of hundreds of exchanges worldwide, operating 24x7 with high volatility.

Why crypto arbitrage is attractive:

• No central price control
• Global access
• Fast-moving market

Example: Rahul bought Ethereum at ₹1,70,000 on Binance and sold it at ₹1,75,000 on Kraken. Profit: ₹5,000 per unit. On trading 5 units, total gain = ₹25,000.

Caution: Transaction fees on both platforms, withdrawal fees, and even a minor delay in transferring tokens could all eat into this margin. If Rahul incurs ₹18,000 in fees, his net profit is reduced to ₹7,000 from ₹25,000. In illiquid markets, he can potentially incur losses.

Crypto Arbitrage Execution

Here’s how a simple crypto arbitrage trade looks in practice:
 

While the trade shows a ₹25,000 profit, real earnings may reduce once you factor in trading fees, transfer costs, and slippage. Smart traders always calculate net profit before executing arbitrage.

Risks & Limitations of Arbitrage

Though arbitrage seems risk-free, it has limitations:

• Transaction Fees: Brokerage or exchange fees can eat into profits.
   
• Time Lag: Price difference may vanish before trade completes.
   
• Slippage: Orders may not execute at the intended price.
   
• Liquidity Risk: Low volume may prevent fast buying/selling.

Example: Neha expected a ₹3,000 profit in arbitrage, but ₹2,000 was lost in fees, and ₹500 in slippage. Her net gain was just ₹500.

Conclusion

Arbitrage is a smart trading method used to take advantage of market inefficiencies. From stocks to crypto, if executed swiftly and with proper analysis, it can yield good profits with minimal risk. However, traders must remain cautious of fees, delays, and liquidity traps.

Like Neha and Rahul, if you understand the market pulse and act fast, arbitrage can become a rewarding strategy in your financial toolkit.
