The bid–ask spread in forex is the difference between two prices quoted for any currency pair: the bid price (what buyers are willing to pay) and the ask price (what sellers are willing to accept).
The bid–ask spread represents the gap between what buyers will pay and what sellers will accept for any currency pair.
When you enter a trade, you always buy at the higher ask price and sell at the lower bid price, meaning every position starts slightly in the negative by the amount of the spread. This spread, measured in pips, represents the primary transaction cost of forex trading.
Think of it like a commission built into the price—the tighter the spread, the less you pay to enter and exit trades. These two-sided quotes simultaneously display both the buying and selling prices available in the market. Brokers and market makers earn revenue from this spread, which varies based on factors like currency pair liquidity, market volatility, and trading session activity.
Understanding the bid and ask prices is essential because the spread directly impacts your trade profitability, as you need the market to move beyond the spread just to break even.
In short: The bid–ask spread is the difference between the buying and selling price of a currency pair, representing the main cost of executing forex trades.
Example in Action
Suppose you want to buy US dollars using South African rand, and your broker quotes USD/ZAR at 18.5000/18.5050. The bid price is 18.5000 (where the broker buys USD from you) and the ask price is 18.5050 (where the broker sells USD to you).
The bid-ask spread is 18.5050 minus 18.5000, which equals 0.0050 or 5 pips. This 5-pip spread represents your immediate transaction cost—if you bought at 18.5050 and sold right back, you'd exit at 18.5000, losing those 5 pips to the spread. Market makers set these spreads as part of their role in providing liquidity to the foreign exchange market. Understanding how to read forex quotes is essential for calculating these spreads accurately and evaluating your true trading costs.
Why It Matters
Understanding the bid-ask spread isn't academic exercise—it directly determines whether an African trader in Lagos, Nairobi, or Johannesburg can turn a profit or watch their account bleed. Every trade starts underwater by the spread amount.
Wide spreads mean needing bigger price moves just to break even. Tight spreads? Lower barrier to profitability. It's math, not magic. Ignore it, pay the price.
Common Questions
Do African Brokers Charge Wider Spreads Than International Brokers?
African brokers generally charge wider spreads than international competitors due to lower regional liquidity, limited market depth, and higher operational costs. International brokers like IC Markets offer spreads from 0.0 pips, while African brokers typically start around 0.9 pips.
How Does Poor Internet Connectivity in Africa Affect Spread Costs?
Poor internet connectivity across Africa causes delayed quote updates and slower trade execution, leading to wider spreads. Traders in Nigeria, Kenya, and Ghana often face slippage and requotes, increasing transaction costs compared to regions with stable, high-speed connections.
Which African Currency Pairs Have the Tightest Bid-Ask Spreads?
Major pairs involving the South African Rand, particularly USD/ZAR and EUR/ZAR, offer the tightest spreads among African currencies due to higher liquidity. However, they remain wider than global major pairs like EUR/USD or GBP/USD.
Can Spread Costs Be Negotiated With Brokers Operating in Africa?
High-volume African traders can negotiate spread costs with some brokers, particularly ECN providers. Account size, trading frequency, and regional deposit methods influence negotiation leverage. Most retail traders accept standard pricing structures without customization options available.
Do Mobile Trading Apps in Africa Show Real-Time Spread Changes?
Leading mobile trading apps from FSCA-regulated brokers like HF Markets, Dukascopy, and RaiseFX display real-time spread changes to African traders. However, availability varies markedly across platforms, with some showing live spreads prominently while others require manual monitoring.
