Spreads in Currency Exchange and Trading

What is a Spread in Financial Markets?

A spread is the difference between the bid price (the price at which a broker or bank is willing to buy a currency) and the ask price (the price at which they are willing to sell it). In simple terms, the spread represents the broker’s profit margin on a trade. This cost is often not advertised clearly, so it’s essential to understand how it works to avoid hidden fees.

How Spreads Work for Currency Brokers and Banks

When you exchange money at a bank or use a currency broker, they quote you two prices:

  • Bid Price: The price at which they will buy your currency.
  • Ask Price: The price at which they will sell you the currency.

For example, if you want to exchange GBP to USD, the broker might quote a bid price of 1.2800 and an ask price of 1.3070. The spread here is 0.0270.

Impact on Transfer Costs

Let’s say you want to convert £10,000 to USD. The bank quotes:

  • Bid Price: 1.2800
  • Ask Price: 1.3070
  • Spread: 0.0270

If you convert £10,000 at the ask price of 1.3070, you receive £10,000 * 1.3070 = $13,070. If you were to convert back at the bid price immediately, you’d get £10,000 * 1.2800 = $12,800. The $270 difference is the cost of the spread.

Hidden Fees in Percentage Terms

To see this as a percentage:

  • Spread Cost: 0.0270
  • Percentage: (0.0270 / 1.2800) * 100 = 2.1%

So, the hidden fee is 2.1% of the transaction. While this might seem small, it adds up, especially with large transactions or frequent exchanges. This is how banks and brokers make money on international money transfers and currency exchanges (other than additional fees that they may levy).

Understanding Pips in Forex Trading

A pip is the smallest price movement in the forex market, usually 0.0001 for most currency pairs.

How Pips are Used in Forex Trading Spreads

Spreads in forex trading are often measured in pips. For example, if the spread is 8 pips, the difference between the bid and ask prices is 0.0008.

Calculating Spread in Pips

Formula: Spread in Pips = (Ask Price – Bid Price) / Pip Value

Example Calculation:

  • Bid Price: 1.3000
  • Ask Price: 1.3008
  • Spread: (1.3008 – 1.3000) / 0.0001 = 8 pips

The Impact of Spreads on Leveraged Forex Trading

In forex trading, leverage allows traders to control large positions with a small amount of capital. For example, a leverage of 400:1 means that with £10,000, you can control £4,000,000 worth of currency.

Example Calculation with Leverage

  • Leverage: 400:1
  • Account Balance: £10,000
  • Position Size: £4,000,000
  • Bid Price: 1.3000
  • Ask Price: 1.3008
  • Spread: 8 pips

If you buy £4,000,000 at 1.3008 with an 8-pip spread:

  • Cost of Spread: £4,000,000 * 0.0008 = $3,200

Not only is this a significant sum, the spread cost ($3,200) reduces your margin buffer, increasing the risk of triggering the stop-loss. This can lead to an amplified loss due to the high leverage, showcasing how spreads can “make or break” trades in high-leverage scenarios.
