The foreign exchange (Forex) market operates 24 hours a day, 5 days a week, and is where currency exchange rates are influenced by countless factors. One of the most striking features of this market is the market reaction to economic data, political events, and global developments.
These reactions can occur instantly within seconds of news releases, or they may last for several days, shaping longer-term trends. Understanding the mechanism and intensity of market reaction helps traders and analysts read price movements more accurately.
News – The Main Catalyst for Volatility
It is undeniable that economic news is the most important factor driving short-term market reaction in Forex. Such announcements usually follow scheduled releases, closely monitored by both traders and analysts.

Key Economic Reports
Key Economic Reports
Some “heavyweight” data that often trigger strong volatility include:
- Interest rate decisions: Directly impact capital flows and currency value.
- Inflation reports (CPI, PPI): Reflect purchasing power and price pressures.
- Retail sales: Gauge consumer spending – a major driver of the economy.
- Labor market data: Unemployment rates and Non-Farm Payrolls (NFP) strongly affect USD and many other currency pairs.
- Trade balance: Indicates import-export activity and foreign exchange demand.
Release Times
Each country has its own data release schedule, for example:
- U.S. (USD): 8:30 – 10:00 a.m. (ET)
- U.K. (GBP): 2:00 – 4:30 a.m. (ET)
- Japan (JPY): 6:50 – 11:30 p.m. (ET)
Knowing these times helps traders anticipate moments of high volatility.
How Market Reaction in Forex Works
Not all news impacts the market equally, and the scale of market reaction depends heavily on the current economic context.
Immediate Reaction
When news deviates significantly from forecasts, market reaction often occurs within seconds to minutes. For instance, if U.S. retail sales are much stronger than expected, the USD may surge instantly.
Prolonged Reaction
Some reports not only spark initial moves but also shape trends for days. Evans & Lyons (2005) found that effects can last up to 4 days, especially for monetary policy-related news.
Factors Determining the Strength of Market Reaction
Beyond the news content itself, several factors influence the strength and direction of market reaction.
Pre-news expectations
Pre-news expectations
If the market has already “priced in” the information (based on forecasts, leaks, or relevant data), the post-announcement reaction may be weaker. Conversely, unexpected information will cause strong volatility.
General economic context
Post-COVID-19, markets have been more sensitive to inflation and interest rate decisions than to GDP growth, showing that context shifts the focus of market reaction over time.
Real-World Example of Market Reaction
A clear case occurred in July 2024 with the EUR/USD pair:
- Before U.S. retail sales data, the pair traded within a narrow 70-pip range.
- When the actual data came out stronger than expected (flat instead of declining, with the prior month revised higher), the USD strengthened sharply, pushing EUR/USD down over 250 pips.
- However, within 24 hours, the drop lost momentum as the broader trend still favored EUR at the time.
This shows how market reaction in Forex can quickly reverse if it does not align with the dominant trend.
The Impact of Forex Options Types
Not only spot trading, forex options also affect price reaction. Exotic options such as Double One-Touch or Double No-Touch are often heavily traded around news releases.
- Double One-Touch: Pays out if price touches either of two barriers before expiry.
- One-Touch: Pays out if price touches a single barrier.
- Double No-Touch: Pays out if price avoids touching both barriers.
These instruments let some traders engage with volatility without predicting exact direction, while still influencing market reaction around key price levels.
