Module 5: Currency Correlations in News Events
When a big US number is released, it does not just move one pair. It sends a ripple across the entire market at the same instant — EUR, GBP, gold, oil and indices all react together. Understanding these correlations lets you pick the best instrument to trade, not just the first one you see.
The US dollar is on one side of most pairs
The USD appears in the majority of major currency pairs. So a single USD event moves all of them simultaneously:
- EUR/USD — if USD strengthens, this pair falls (because USD is the second currency).
- GBP/USD — same: USD strength pushes it down.
- USD/JPY — USD is first here, so USD strength pushes it up.
- USD/CHF — also rises on USD strength.
So on a strong US jobs report: EUR/USD and GBP/USD drop, while USD/JPY and USD/CHF rise. They mirror each other.
Gold moves opposite to the dollar
Gold (XAU/USD) is priced in dollars and pays no interest. When the USD strengthens and interest rates look set to stay high, gold usually falls. When the USD weakens, gold rises. Gold is one of the most reactive instruments to US news — often moving $20–50 on a single NFP or CPI.
Stock indices and risk sentiment
Indices like the S&P 500 and Nasdaq react to interest rate expectations. Higher rates are generally bad for stocks (borrowing costs rise, future profits are discounted more heavily). So a hot inflation number can push the dollar up and stocks down at the same time.
Commodity currencies
The Australian dollar (AUD), Canadian dollar (CAD) and New Zealand dollar (NZD) are linked to commodity prices and global growth. They are sensitive to risk sentiment — when traders are fearful (risk-off), these currencies tend to fall, and safe havens (USD, JPY, CHF, gold) rise.
How to use correlations to pick the best trade
When you have a clear directional view from a US release, look across the correlated instruments and choose the one showing the cleanest chart and the strongest reaction. For example, if USD is strengthening, you might find EUR/USD is hovering at support but USD/JPY is breaking cleanly higher — the Yen pair is the better trade. Correlation gives you choices; pick the strongest.
A warning about over-exposure
Because these instruments move together, taking short EUR/USD and long USD/JPY and short gold all at once is effectively the same trade three times. If USD reverses, all three lose together. Treat correlated positions as one trade for risk purposes.
