Floating Exchange Rate
A floating exchange rate is one set mainly by supply and demand in the foreign exchange market rather than fixed by the authorities. The central bank may intervene to calm disorderly moves but does not defend a particular level.
Also called: floating currency · free float · flexible exchange rate · floating regime
Under a float, a currency's price moves with trade flows, investment, interest rate expectations and sentiment. The country keeps its monetary policy for domestic goals, and the exchange rate absorbs shocks that a peg would push onto interest rates or reserves. In the terms of the impossible trinity, it pairs free capital movement with an independent monetary policy. Major currencies have floated since the Bretton Woods system of fixed rates broke down in the early 1970s.
The IMF classifies regimes by what countries do rather than what they declare. In its framework a floating arrangement is largely market-determined, with no predictable path, and any intervention aims to smooth fluctuations rather than hold a level. Free floating is the stricter category: intervention is exceptional, aimed at disorderly markets, and disclosed. Between floats and hard pegs sit stabilised, crawling and other managed arrangements.
Floating does not mean frictionless. Prices for thinly traded currencies can gap overnight, spreads widen in stress, and a central bank that calls its currency floating may still lean on banks informally. For cross-border payments the practical consequence is exchange-rate risk between quote and settlement, which firms manage with short quote validity, forward contracts and other forms of hedging.
In practice
Declared and actual regimes differ. When judging how a currency will behave, use the IMF's de facto classification rather than the central bank's own description.
Example
A UK importer agrees to pay US$500,000 in 60 days when GBP/USD is 1.30, a cost of about £384,600. If sterling falls to 1.25 the bill becomes £400,000; the £15,400 difference is the price of leaving the exposure open.

- Currency PegA currency peg is a policy under which a central bank fixes its currency's exchange rate to another currency or a basket and stands ready to buy and sell at that rate. The peg lasts only as long as the reserves and credibility behind it.
- Impossible TrinityThe impossible trinity holds that a country cannot have a fixed exchange rate, free movement of capital and an independent monetary policy all at once. It can choose any two, and giving up the third is the price of the other two.
- HedgingHedging is taking a position that gains when an existing exposure loses, so that a move in a price, rate or currency leaves the combined result roughly unchanged. A hedge reduces uncertainty; it does not guarantee a profit or rule out a loss.
- Forward ContractA forward contract is an agreement to exchange one currency for another on a future date at a rate fixed today. It creates a binding obligation on both sides — which is what makes it useful for certainty and dangerous if the underlying payment never happens.
- DevaluationDevaluation is a deliberate official reduction in the value of a currency that is fixed or managed against another. It makes exports cheaper and imports dearer overnight, and is usually forced by reserves running too low to defend the old rate.
