Why foreign exchange matters

FX is central to global portfolios and operates across dealer, electronic, exchange, and customer markets. It carries market, counterparty, settlement, liquidity, and jurisdictional risk.

How it is applied

Participants use spot, forwards, swaps, options, and futures. Treasury teams manage value dates, cutoffs, collateral, counterparties, confirmations, and payment-versus-payment settlement.

Portfolio example

A company expecting euro revenue sells euros forward for dollars, converting uncertain future dollar value into a contracted amount.

How to interpret it

Trading volume does not imply equal liquidity in every pair or time zone. Spot activity and FX swaps serve different economic purposes.

Limitations and common misconceptions

The market is decentralized, quotes vary, and settlement failures can create principal risk. Controls and sanctions may restrict convertibility.
