What Is It?
Foreign exchange (Forex/FX) is the global market for trading currencies. With over $7 trillion daily volume, it is the largest and most liquid financial market. Currencies trade in pairs (EUR/USD, USD/JPY), reflecting relative values.
Origin
Currency trading evolved from the gold standard (abandoned 1971) to floating rates. Modern FX markets developed with electronic trading in the 1990s-2000s. Retail FX trading expanded through online brokers. The market is decentralized across global banking centers.
Why It Matters
FX rates affect international trade, investment returns, inflation, and corporate earnings. Multinationals hedge currency exposure. Central banks intervene to manage exchange rates. Carry trades exploit interest rate differentials.

Market Mechanics
Spot FX settles in two days; forwards and swaps extend maturity. Major pairs involve USD; crosses exclude it. Pips measure price movements. Leverage is high (50:1+), amplifying gains and losses. Liquidity is deepest in London and New York sessions.
How It Behaves
Currencies trend with interest rate differentials, economic growth, and risk sentiment. Safe havens (USD, JPY, CHF) appreciate in crises. Emerging market currencies are more volatile. Central bank intervention can override fundamentals short-term.
