How it works
Currencies trade in pairs. EUR/USD means the cost of one euro in dollars. If EUR/USD = 1.085, one euro costs 1.085 dollars. When you 'buy EUR/USD', you're buying euros with dollars; the trade profits if the euro strengthens relative to the dollar.
Who participates
FX has a layered structure. Most retail traders interact with brokers who aggregate from these tiers.
- →Central banks — set interest rate policy, intervene in extreme moves
- →Commercial banks — facilitate corporate flows, run prop trading desks
- →Hedge funds & asset managers — speculative and macro positioning
- →Corporations — hedge cross-border revenue
- →Retail traders — via FX brokers, typically with leverage
Pair categories
FX pairs fall into three tiers based on liquidity and which currencies are involved.
- →Majors — USD + one of the top 7 (EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD, NZD/USD)
- →Minors / crosses — no USD (EUR/GBP, EUR/JPY, GBP/JPY)
- →Exotics — one major + one emerging-market currency (USD/TRY, USD/ZAR) — wider spreads, higher volatility
