Floating exchange rate in the context of "Jamaica Accords"

A fixed exchange rate, often called a pegged exchange rate or pegging, is a type of exchange rate regime in which a currency's value is fixed, or pegged, by a monetary authority against the value of another currency, a basket of other currencies, or another measure of value, such as gold or silver.

There are benefits and risks to using a fixed exchange rate system. A fixed exchange rate is typically used to stabilize the exchange rate of a currency by directly fixing its value in a predetermined ratio to a different, more stable, or more internationally prevalent currency (or currencies) to which the currency is pegged. In doing so, the exchange rate between the currency and its peg does not change based on market conditions, unlike in a floating (flexible) exchange regime. This makes trade and investments between the two currency areas easier and more predictable and is especially useful for small economies that borrow primarily in foreign currency and in which external trade forms a large part of their GDP.

In macroeconomics and modern monetary policy, a devaluation is an official lowering of the value of a country's currency within a fixed exchange-rate system, in which a monetary authority formally sets a lower exchange rate of the national currency in relation to a foreign reference currency or currency basket. The opposite of devaluation, a change in the exchange rate making the domestic currency more expensive, is called a revaluation. A monetary authority (e.g., a central bank) maintains a fixed value of its currency by being ready to buy or sell foreign currency with the domestic currency at a stated rate; a devaluation is an indication that the monetary authority will buy and sell foreign currency at a lower rate.

However, under a floating exchange rate system (in which exchange rates are determined by market forces acting on the foreign exchange market, and not by government or central bank policy actions), a decrease in a currency's value relative to other major currency benchmarks is instead called depreciation; likewise, an increase in the currency's value is called appreciation.

Modern Monetary Theory or Modern Money Theory (MMT) is a macroeconomic theory that describes the nature of money within a fiat, floating exchange rate system. MMT synthesizes ideas from the state theory of money of Georg Friedrich Knapp (also known as chartalism) and the credit theory of money of Alfred Mitchell-Innes, the functional finance proposals of Abba Lerner, Hyman Minsky's views on the banking system and Wynne Godley's sectoral balances approach. Economists Warren Mosler, L. Randall Wray, Stephanie Kelton, Bill Mitchell and Pavlina R. Tcherneva are largely responsible for reviving the idea of chartalism as an explanation of money creation.

MMT frames government spending and taxation differently to most orthodox frameworks, and instead relies on functionalist readings of historical events and evidence, such as the use of Tally sticks, or the creation of The Bank of England. MMT states that the government is the monopoly issuer of its currency and therefore must spend currency into existence before any tax revenue can be collected. The government spends currency into existence and taxpayers use that currency to pay their obligations to the state. This means that taxes cannot fund public spending in a nominal monetary flow sense, as the government cannot collect money back in taxes until after it is has been issued into the economy. In this kind of monetary system, the government is never constrained in its ability to pay, rather the limits are the real resources available for purchase in the state's currency.

An exchange rate regime is a way a monetary authority of a country or currency union manages the currency about other currencies and the foreign exchange market. It is closely related to monetary policy and the two are generally dependent on many of the same factors, such as economic scale and openness, inflation rate, the elasticity of the labor market, financial market development, and capital mobility.

There is no correct or optimal exchange rate. However, the exchange rate has distributional consequences with winners and losers in the domestic economy. Exporters and importers lose with currency appreciation while consumers and domestic oriented industries benefit from currency appreciation. A currency depreciation has the opposite effect.

In macroeconomics, crawling peg is an exchange rate regime that allows currency depreciation or appreciation to happen gradually. It is usually seen as a part of a fixed exchange rate regime.

The system is a method to fully use the key attributes of the fixed exchange regimes, as well as the flexibility of the floating exchange rate regime. The system is shaped to peg at a certain value, but at the same time is designed to "glide" to respond to external market uncertainties.

A currency band is a range of values for the exchange rate for a country’s currency which the country’s central bank acts to keep the exchange rate within.

The central bank selects a range, or "band", of values at which to set their currency, and will intervene in the market or return to a fixed exchange rate if the value of their currency shifts outside this band. This allows for some revaluation, but tends to stabilize the currency's value within the band. In this sense, it is a compromise between a fixed (or "pegged") exchange rate and a floating exchange rate.
