If you’re trading Forex, you may have noticed that spreads sometimes widen unexpectedly. This can be frustrating for traders, especially beginners, because it increases trading costs and affects profit potential. Understanding why spreads widen during news events and periods of market volatility is essential for managing risk and making smarter trading decisions.
What Causes Spreads to Widen?
A spread is the difference between the bid price (what you can sell a currency for) and the ask price (what you can buy it for). Brokers earn money through this spread, and it is influenced by market liquidity and volatility.
During periods of low liquidity or high volatility, brokers may widen spreads to protect themselves from sudden price swings. This means your trade costs more to enter and exit. For beginners, it’s important to know how to calculate spreads. You can see a detailed guide here: how to calculate spread in Forex.
Major Factors Behind Widening Spreads
1. Economic News Releases
High-impact news, such as:
- Interest rate decisions
- Employment reports (e.g., Non-Farm Payrolls)
- GDP announcements
- Inflation data
…can cause rapid price movements. Liquidity can drop during these periods because many market participants hesitate to enter positions, leading to wider spreads.
2. Market Volatility
Volatility occurs when prices move quickly and unpredictably. During volatile markets:
- Brokers increase spreads to manage risk.
- The difference between bid and ask prices can grow substantially.
- Traders may face higher costs for entering trades.
For example, a normally tight EUR/USD spread of 1 pip may widen to 3–5 pips during a major economic announcement.
3. Low Liquidity Periods
Spreads can also widen when market liquidity drops, such as:
- Overnight sessions
- Holidays
- Thinly traded exotic pairs
Low liquidity means fewer buyers and sellers, which increases the gap between bid and ask prices.
How Widened Spreads Affect Your Trades
When spreads widen:
- Higher Trading Costs: You pay more to enter and exit trades.
- Lower Profits: Your trade must move further in your favor to break even.
- Greater Risk: Stop-loss orders may be triggered more easily due to wider spreads.
For instance, if you buy EUR/USD with a 2-pip spread under normal conditions, but the spread widens to 5 pips during a news release, your trade starts 3 pips deeper in the red than expected.
Fixed vs Variable Spreads During Volatility
- Fixed Spreads: Remain relatively stable but may still widen slightly during extreme market events.
- Variable Spreads: Can widen significantly, reflecting the real-time risk and liquidity conditions.
Traders using variable spreads need to monitor the market closely during news events to avoid unexpected costs.
Practical Example
Imagine you trade GBP/USD with the following:
- Normal spread: 2 pips
- During news: 6 pips
- Lot size: 1 mini lot (10,000 units)
Normal cost: 2 × $1 = $2
Cost during news: 6 × $1 = $6
This shows how entering trades during high-impact news can triple your spread costs, reducing profitability if not accounted for.
Tips to Manage Spread Widening
- Avoid trading during major news releases if you’re not an experienced news trader.
- Monitor economic calendars to anticipate high-impact events.
- Focus on high-liquidity pairs like EUR/USD and USD/JPY to minimize spread widening.
- Use brokers with competitive spreads, such as low spread Forex brokers, which tend to manage spread increases better during volatility.
- Consider using limit orders instead of market orders to control entry points.
Why Understanding Spread Widening Matters
Many beginners fail to consider spread widening when calculating potential profits and losses. By understanding when and why spreads increase, you can:
- Reduce trading costs
- Avoid unexpected losses
- Plan trades more strategically
- Choose the right times and currency pairs for trading
How to Prepare for Volatile Markets
- Check news calendars daily to avoid trading during high-risk periods.
- Use demo accounts to practice trading during simulated volatility.
- Monitor spreads in real-time on your trading platform.
- Adjust lot sizes to manage risk when spreads are unusually high.
Being proactive helps you avoid being caught off-guard by sudden spread increases.
Conclusion
Spreads widen during news events and volatile market conditions primarily due to lower liquidity and increased broker risk. Traders who ignore this may pay more than expected, impacting profits and risk management.
By understanding the causes of spread widening, focusing on major currency pairs, using low spread Forex brokers, and carefully planning trades, you can navigate volatile markets more effectively.
Being aware of spreads and their behavior under different market conditions is essential for any trader, from beginners to experienced professionals.
