What is a spread? How does it differ from a commission?


The spread is a term used in financial markets to describe the difference between the buying and selling prices. It's crucial in trading stocks, forex, commodities, and reflects transaction costs.

What is a Spread?

The term spread is commonly used in financial markets to describe the difference or "spread" between the bid price and the ask price. It is an important concept in trading securities, foreign exchange, commodities, and other transactions.

Essentially, the spread is the price difference between the buying price and the selling price. It can also be understood as the transaction cost between the bid and ask prices. The bid price is the highest price the market is willing to pay for a financial instrument, while the ask price is the lowest price at which the market is willing to sell that financial instrument. Spreads are typically set by brokers or trading platforms and are used to cover the costs of providing trading services and to generate profits.

How is the Spread Determined?

The size of the spread depends on the specific financial product and market conditions. In markets with high liquidity and intense competition, spreads tend to be smaller. Conversely, in markets with low liquidity or significant volatility, spreads may widen. Spreads play a crucial role in trading as they directly impact the trading costs and profits for investors.

What Impact Does the Spread Have on Investment?

For investors, understanding and comparing the spreads offered by different brokers or trading platforms is important because a lower spread means lower transaction costs, thereby enhancing potential profits. Additionally, the spread can reflect market liquidity and trading conditions, so investors should pay attention to the size and variation of spreads when selecting a trading platform and executing trades.

What is the Difference Between Spread and Commission?

Spread and commission are two different concepts in financial trading, both related to transaction costs, but they differ in nature.

  1. Spread: The spread is the price difference between the buying and selling prices. In trading, brokers or trading platforms typically set a price difference (the spread) between the bid and ask prices as the cost and profit of providing trading services. The spread can be seen as an implicit fee because it directly affects the cost of the transaction and the investor's profit. A lower spread is generally more favorable for investors because it means lower transaction costs.
  2. Commission: The commission is the fee investors pay to brokers or trading platforms when executing trades. It can be a fixed fee or a percentage of the transaction volume. This is a direct cost, usually charged upon completion of each trade. Commission rates may vary depending on the broker, trading platform, traded products, and the scale of the trade. Some brokers might offer commission-free trades, typically incorporating the transaction costs into the spread.

Therefore, spreads and commissions represent two different types of transaction costs. The spread is the price difference between the bid and ask prices, incorporated in the trading price, while the commission is a fee paid directly to the broker or trading platform. Investors need to consider both spreads and commissions when choosing a trading platform and making trades, evaluating different cost structures based on their trading needs and preferences.
