A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.

Monetary reform is any movement or theory that proposes a system of supplying money and financing the economy that is different from the current system.
A store of value is any commodity or asset that would normally retain purchasing power into the future and is the function of the asset that can be saved, retrieved and exchanged at a later time, and be predictably useful when retrieved.
In economics, a medium of exchange is any item that is widely acceptable in exchange for goods and services. In modern economies, the most commonly used medium of exchange is currency. Most forms of money are categorised as mediums of exchange, including commodity money, representative money, cryptocurrency, and most commonly fiat money. Representative and fiat money most widely exist in digital form as well as physical tokens, for example coins and notes.
International finance is the branch of monetary and macroeconomic interrelations between two or more countries. International finance examines the dynamics of the global financial system, international monetary systems, balance of payments, exchange rates, foreign direct investment, and how these topics relate to international trade.

Modern monetary theory or modern money theory (MMT) is a heterodox macroeconomic theory that describes currency as a public monopoly and unemployment as evidence that a currency monopolist is overly restricting the supply of the financial assets needed to pay taxes and satisfy savings desires. According to MMT, governments do not need to worry about accumulating debt since they can pay interest by printing money. MMT argues that the primary risk once the economy reaches full employment is inflation, which acts as the only constraint on spending. MMT also argues that inflation can be controlled by increasing taxes on everyone, to reduce the spending capacity of the private sector.
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are: medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.
Monetary inflation is a sustained increase in the money supply of a country. Depending on many factors, especially public expectations, the fundamental state and development of the economy, and the transmission mechanism, it is likely to result in price inflation, which is usually just called "inflation", which is a rise in the general level of prices of goods and services.

Fiat money is a type of government issued currency that is not backed by a precious metal, such as gold or silver, nor by any other tangible asset or commodity. Fiat currency is typically designated by the issuing government to be legal tender, and is authorized by government regulation. Since the end of the Bretton Woods system in 1975, the major currencies in the world are fiat money.

The Return of Depression Economics and the Crisis of 2008 is a non-fiction book by American economist and Nobel Prize winner Paul Krugman, written in response to growing socio-political discourse on the return of economic conditions similar to The Great Depression. The book was first published in 1999 and later updated in 2008 following his Nobel Prize of Economics. The Return of Depression Economics uses Keynesian analysis of past economics crisis, drawing parallels between the 2008 financial crisis and the Great Depression. Krugman challenges orthodox economic notions of restricted government spending, deregulation of markets and the efficient market hypothesis. Krugman offers policy recommendations for the prevention of future financial crises and suggests that policymakers "relearn the lessons our grandfathers were taught by the Great Depression" and prop up spending and enable broader access to credit.
In macroeconomics, chartalism is the theory of money that money originated historically with states' attempts to direct economic activity rather than as a spontaneous solution to the problems with barter or as a means with which to tokenize debt, and that fiat currency has value in exchange because of sovereign power to levy taxes on economic activity payable in the currency they issue.
A central bank digital currency is a digital currency issued by a central bank, rather than by a commercial bank. It is also a liability of the central bank, unless it is dividend-paying, then it is an ownership stake in the central bank, and is a new form of legal tender, unlike regular retail CBDC which is denominated in the sovereign currency, as is the case with physical banknotes, coin and existing reserves.
El Salvador became the first country in the world to use bitcoin as legal tender, after having been adopted as such by the Legislative Assembly of El Salvador in 2021. It has been promoted by Nayib Bukele, the president of El Salvador, who claimed that it would improve the economy by making banking easier for Salvadorans, and that it would encourage foreign investment. In 2022, more Salvadorians had Bitcoin Lightning wallets than bank accounts. In 2023, Bukele has credited this change to fueling the increase in tourism to El Salvador by 95%. The adoption has been criticized both internationally and within El Salvador, due to the volatility of Bitcoin, its environmental impact, and lack of transparency regarding the government's fiscal policy. In 2024, El Salvador agreed to partially limit its involvement with Bitcoin as part of a deal made with the International Monetary Fund (IMF).
