The investors who do that are called arbitrageurs. They always look for price differences and buy a security at a lower price and sell it at a higher price. This allows them to gain money with no risk. In this course, we will shed the light on the triangular arbitrage, and give you all you need to know about this forex strategy.

## Triangular Arbitrage guide

**What is triangular arbitrage ?**

Triangular arbitrage is a trading strategy that represents taking opportunities from the discrepancy between three foreign currencies in the foreign exchange market ( forex ) . The triangular arbitrage happens when the market is inefficient and differential in supply or demand which leads to a mismatch between prices. This process executes through the successive exchange of one currency to another when there is a difference in the quoted prices for the underlying currencies. This means that the forex investor has to convert one currency to another, then convert it again to another currency, and after that convert it back to the original currency. This process takes only seconds. Moreover, you take advantage of this opportunity when the exchange rate of a currency is different from the cross-exchange rate. This arises when one market is overvalued and the other is undervalued.

**How does the triangular arbitrage work ?**

The triangular arbitrage occurs when one market is overvalued and the other is undervalued. This inefficiency leads to discrepancies in prices. In this case, participants in the foreign exchange market ( forex ) , such as international banks, will exploit this opportunity to generate profits. However, the price difference between the exchange rates is very small (fractions of cent). So you have to trade a considerable volume of transactions to get a feasible arbitrage. In fact, triangular arbitrage is a risk-free benefit. This means that you can generate money from the arbitrage without exposure to any risk. The investor makes 3 simultaneous trades, he/she buys one currency and sells another, and the base currency is the third one.

### Example

let’s take an example to understand how this process works. Say that a trader has 2 million and he finds the following exchange rates in the market: EUR/ USD = 0.8820, EUR / GBP = 1.3360, USD / GBP = 1.5162

cross-rate = 0.8812 × 1.5162 = 1.3361

You have to Sell $ for € and at the same time sell € for £, then sell £ for $. Here are the steps you must follow for the triangular arbitrage:

- Sell $ for €: $ 2 million × 0.8820 = 1 764 000
- Sell € for £: 1 764 000 / 1.3360 = 1 320 359.28
- Sell £ for $: 1 320 359.28 × 1.5162 = 2 001 928.74

The profit gained from this triangular arbitrage will be 2 064 631.9 – 2 000 000 = 1 928.74. we can conclude from this calculation that even with the use of a large capital you gain a small profit. this is due to the small price discrepancy. in the real life, the profit would be smaller, since in this example we did not consider the transaction costs.
