Understanding what drives currency prices is essential for forex traders. Unlike stocks, which are influenced primarily by company performance, currencies respond to a complex web of macroeconomic factors.
Interest Rates: The Primary Driver
Interest rates are the single most important factor influencing exchange rates.
Why Interest Rates Matter
Higher interest rates attract foreign capital seeking better returns. This increased demand strengthens the currency.
Central Banks
Each major currency has a central bank setting interest rates:
- USD: Federal Reserve (Fed)
- EUR: European Central Bank (ECB)
- GBP: Bank of England (BOE)
- JPY: Bank of Japan (BOJ)
What to Watch
- Interest rate decisions (scheduled meetings)
- Forward guidance (hints about future policy)
- Inflation data (influences rate decisions)
Trading tip: The market often prices in expected rate changes before they happen. Surprises move markets most.
Economic Data
Strong economic data typically strengthens a currency; weak data weakens it.
Key Data Points
Employment:
- US Non-Farm Payrolls (NFP) – the big one
- Unemployment rate
- Wage growth
Inflation:
- Consumer Price Index (CPI)
- Producer Price Index (PPI)
- PCE (Fed's preferred measure)
Growth:
- GDP reports
- Manufacturing data (PMI)
- Retail sales
Consumer Confidence:
- University of Michigan Sentiment
- Consumer Confidence Index
Economic Calendar
Successful forex traders live by the economic calendar. Know when major releases are scheduled and be prepared for volatility.
Trade Balance
A country's trade balance affects currency flows.
Trade Surplus
More exports than imports = foreigners need your currency = currency strengthens
Trade Deficit
More imports than exports = you need foreign currency = currency weakens
Long-term factor: Trade balances influence currencies over months and years, not day-to-day.
Political Stability
Political events can dramatically move currencies.
Key Political Factors
- Elections and changes in government
- Geopolitical conflicts
- Trade wars and sanctions
- Regulatory changes
Safe Haven Flows
During global uncertainty, money flows to "safe haven" currencies:
- USD (world's reserve currency)
- JPY (low rates, stable economy)
- CHF (Swiss neutrality, banking stability)
Market Sentiment: Risk-On vs. Risk-Off
Global risk appetite affects currency flows.
Risk-On Environment
Investors seek higher returns in riskier assets:
- "Risk currencies" strengthen (AUD, NZD, CAD, emerging markets)
- Safe havens weaken (JPY, CHF)
Risk-Off Environment
Investors flee to safety:
- Safe havens strengthen (USD, JPY, CHF)
- Risk currencies weaken
Watch: Stock market performance, VIX (fear index), bond yields
Interventions
Sometimes central banks directly intervene in currency markets.
Types of Intervention
- Verbal intervention: Officials make statements to influence currency direction
- Actual intervention: Central bank buys or sells currency in the market
Examples
- Bank of Japan is known for intervening when yen strengthens too much
- Swiss National Bank has a history of defending currency levels
Trading tip: Fighting a central bank is usually a losing proposition.
Technical Factors
While fundamentals drive long-term direction, technicals matter for timing:
- Key support and resistance levels
- Round number psychology
- Trend lines and moving averages
- Option expiration levels
Many forex moves occur at technically significant levels, not randomly.
Putting It Together
Successful forex analysis combines:
- Know the fundamentals: Which economy is stronger? Where are rates headed?
- Watch the data: What events are scheduled? What were expectations vs. reality?
- Track sentiment: Risk-on or risk-off? What's the market mood?
- Use technicals: Where are key levels? What's the trend?
