EUR/USD represents the exchange rate between the eurozone and the United States, the two largest developed economies. It accounts for roughly 20-25% of all forex turnover, which makes it the most liquid, most closely analyzed, and generally the most 'technical' pair to trade — meaning chart patterns and support/resistance levels tend to be respected more reliably than in thinner markets.
Primary Drivers
- ▸Fed vs ECB monetary policy — the relative pace of rate hikes or cuts is the single biggest driver.
- ▸US and eurozone inflation (CPI) releases, which shape rate expectations.
- ▸Employment data — US Non-Farm Payrolls is the single most-watched release for USD.
- ▸PMI and GDP growth data comparing the two economies.
- ▸Broad dollar sentiment (DXY) driven by global risk appetite.
Session Behavior
EUR/USD is most active during the London session and the London-New York overlap (roughly 13:00-17:00 UTC), when both European and American participants are trading simultaneously. The Asian session tends to be quieter and range-bound, often just consolidating the prior day's move before London opens and injects fresh volume.
Typical Volatility
On a normal day, EUR/USD moves 50-80 pips. Around major US data releases (CPI, NFP, FOMC decisions) or ECB rate announcements, that range can double or triple within minutes. Because the pair is so liquid, sudden moves are usually driven by genuine news rather than thin-liquidity spikes.
Worked Example: Trading Around an ECB Decision
Suppose EUR/USD is trading at 1.0800 ahead of an ECB rate decision, and the market broadly expects a hold. The ECB instead signals it may cut rates sooner than expected due to weakening inflation. The euro immediately weakens because lower relative rates make it less attractive to hold. EUR/USD drops to 1.0740 within the hour — a 60-pip move driven purely by the rate-differential shift.
| Step | Detail |
|---|---|
| Entry | Short at 1.0790 after the dovish surprise is confirmed |
| Stop loss | 1.0820 (above the pre-announcement range) |
| Target | 1.0730 (next support level) |
| Risk:Reward | 30 pips risk vs 60 pips reward = 1:2 |
Key Correlations
EUR/USD tends to move inversely to USD/CHF (both express dollar strength against a European currency) and has a moderate positive correlation with GBP/USD. It's also inversely correlated with the DXY dollar index by construction, since the euro makes up about 57% of that index's weighting.
Because EUR/USD reacts to data from two economic zones, an economic calendar covering both the US and eurozone is essential. Missing a scheduled ECB or Fed speech is one of the most common ways new traders get caught offside.
