Currency in the context of Local currency

A civilization (also spelled civilisation in British English) is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems).

Civilizations are organized around densely populated settlements, divided into more or less rigid hierarchical social classes of division of labour, often with a ruling elite and subordinate urban and rural populations, which engage in intensive agriculture, mining, small-scale manufacture and trade. Civilization concentrates power, extending human control over the rest of nature, including over other human beings. Civilizations are characterized by elaborate agriculture, architecture, infrastructure, technological advancement, currency, taxation, regulation, and specialization of labour.

The Singapore dollar (sign: S$; code: SGD) is the official currency of the Republic of Singapore. It is divided into 100 cents (Malay: sen, Chinese: 分; pinyin: fēn, Tamil: காசு, romanized: kācu). It is normally abbreviated with the dollar sign $, or S$ to distinguish it from other dollar-denominated currencies. The Monetary Authority of Singapore (MAS) issues the banknotes and coins of the Singapore dollar.

As of 2024, the Singapore dollar is the 13th most traded currency in the world. Apart from its use in Singapore, the Singapore dollar is also accepted as customary tender in Brunei according to the Currency Interchangeability Agreement between the Monetary Authority of Singapore and the Autoriti Monetari Brunei Darussalam (Monetary Authority of Brunei Darussalam). Likewise, the Brunei dollar is also customarily accepted in Singapore.

In finance, an exchange rate is the rate at which one currency will be exchanged for another currency. Currencies are most commonly national currencies, but may be sub-national as in the case of Hong Kong or supra-national as in the case of the euro.

The exchange rate is also regarded as the value of one country's currency in relation to another currency. For example, an interbank exchange rate of 141 Japanese yen to the United States dollar means that ¥141 will be exchanged for US$1 or that US$1 will be exchanged for ¥141. In this case it is said that the price of a dollar in relation to yen is ¥141, or equivalently that the price of a yen in relation to dollars is $1/141.

Purchasing power parity (PPP) is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currencies. PPP is effectively the ratio of the price of a market basket at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the market exchange rate because of tariffs, and other transaction costs.

The purchasing power parity indicator can be used to compare economies regarding their gross domestic product (GDP), labour productivity and actual individual consumption, and in some cases to analyse price convergence and to compare the cost of living between places. The calculation of the PPP, according to the OECD, is made through a basket of goods that contains a "final product list [that] covers around 3,000 consumer goods and services, 30 occupations in government, 200 types of equipment goods and about 15 construction projects".

The United States dollar (symbol: $; currency code: USD) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.

The U.S. dollar was originally defined under a bimetallic standard of 371.25 grains (24.057 g) (0.7734375 troy ounces) fine silver or, from 1834, 23.22 grains (1.505 g) fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important international reserve currency after the First World War, and displaced the pound sterling as the world's primary reserve currency by the Bretton Woods Agreement towards the end of the Second World War. The dollar is the most widely used currency in international transactions, and a free-floating currency. It is also the official currency in several countries and the de facto currency in many others, with Federal Reserve Notes (and, in a few cases, U.S. coins) used in circulation.

A treasury is either

• A government department related to finance and taxation, a finance ministry; in a business context, corporate treasury.
• A place or location where treasure, such as currency or precious items are kept. These can be state or royal property, church treasure or in private ownership.

The head of a treasury is typically known as a treasurer. This position may not necessarily have the final control over the actions of the treasury, particularly if they are not an elected representative.

The dinar (/dɪˈnɑːr/, /ˈdiːnɑː(r)/) is the name of the principal currency unit in several countries near the Mediterranean Sea, with a more widespread historical use. The English word "dinar" is the transliteration of the Arabic دينار (dīnār), which was borrowed via the Syriac dīnarā from the Latin dēnārius.

The modern gold dinar is a projected bullion gold coin, and as of 2019 is not issued as an official currency by any state.

The Serdi were a Celtic tribe inhabiting Thrace. They were located around Serdica (Bulgarian: Сердика, romanized: Serdika; Latin: Ulpia Serdica; Greek: Σαρδική o Σαρδῶν πόλις, romanized: Sardike o Sardon polis), now Sofia in Bulgaria, which reflects their ethnonym. They would have established themselves in this area during the Celtic migrations at the end of the 4th century BC, though there is no evidence of their existence before the 1st century BC. Serdi are among traditional tribal names reported into the Roman era. They were gradually Thracianized over the centuries but retained their Celtic character in material culture up to a late date. According to other sources they may have been simply of Thracian origin; according to others they may have been of mixed Thraco-Celtic origin.

An economy is an area of the production, distribution and trade, as well as consumption of goods and services. In general, it is defined as a social domain that emphasize the practices, discourses, and material expressions associated with the production, use, and management of resources. A given economy is a set of processes that involves its culture, values, education, technological evolution, history, social organization, political structure, legal systems, and natural resources as main factors. These factors give context, content, and set the conditions and parameters in which an economy functions. In other words, the economic domain is a social domain of interrelated human practices and transactions that does not stand alone.

Economic agents can be individuals, businesses, organizations, or governments. Economic transactions occur when two groups or parties agree to the value or price of the transacted good or service, commonly expressed in a certain currency. However, monetary transactions only account for a small part of the economic domain.

A currency symbol or currency sign is a graphic symbol used to denote a currency unit. Usually it is defined by a monetary authority, such as the national central bank for the currency concerned.

A symbol may be positioned in various ways, according to national convention: before, after or between the numeric amounts: $2.50, 2,50€ and 250.

The cent is a monetary unit of many national currencies that equals a hundredth (1⁄100) of the basic monetary unit. The word derives from the Latin centum, 'hundred'.

The cent sign is commonly a simple minuscule (lower case) letter c. In North America, the c is crossed by a diagonal or vertical stroke (depending on typeface), yielding the character ¢.

The dollar sign, also known as the peso sign, is a currency symbol consisting of a capital ⟨S⟩ crossed with one or two vertical strokes ($ or depending on typeface), used to indicate the unit of various currencies around the world, including most currencies denominated "dollar" or "peso". The explicitly double-barred sign is called cifrão in the Portuguese language.

The sign is also used in several compound currency symbols, such as the Brazilian real (R$) and the United States dollar (US$): in local use, the nationality prefix is usually omitted. In countries that have other currency symbols, the US dollar is often assumed and the "US" prefix omitted.

The Brunei dollar (sign: B$, Malay: ringgit, will be renamed to dolar Brunei starting from the 2026 series; currency code: BND), has been the currency of the Sultanate of Brunei since 1967. It is normally abbreviated with the dollar sign $, or alternatively B$ to distinguish it from other dollar-denominated currencies. The currency is divided into 100 cents (Malay: sen) and is issued by the Brunei Darussalam Central Bank.

Under a Currency Interchangeability Agreement in 1967, the Brunei dollar is interchangeable with the Singapore dollar at par. As such, the Brunei dollar is accepted in Singapore as "customary tender"; likewise, the Singapore dollar is accepted in Brunei.

Finance refers to monetary resources and to the study and discipline of money, currency, assets and liabilities. As a subject of study, it is a field of Business Administration which involves the planning, organizing, leading, and controlling of an organization's resources to achieve its goals. Based on the scope of financial activities in financial systems, the discipline can be divided into personal, corporate, and public finance.

In these financial systems, assets are bought, sold, or traded as financial instruments, such as currencies, loans, bonds, shares, stocks, options, futures, swaps, etc. Assets can also be banked, invested, and insured to maximize value and minimize loss. In practice, risks are always present in any financial action and entities.

Gross domestic product (GDP) is the market value of all final goods and services from a nation in a given year. Countries are sorted by nominal GDP estimates from financial and statistical institutions, which are calculated at market or government official exchange rates. Nominal GDP does not take into account differences in the cost of living in different countries, and the results can vary greatly from one year to another based on fluctuations in the exchange rates of the country's currency. Such fluctuations may change a country's ranking from one year to the next, even though they often make little or no difference in the standard of living of its population.

Comparisons of national wealth are also frequently made based on purchasing power parity (PPP), to adjust for differences in the cost of living in different countries. Other metrics, nominal GDP per capita and a corresponding GDP (PPP) per capita, are used for comparing national standard of living. On the whole, PPP per capita figures are less spread than nominal GDP per capita figures.

A currency union (also known as monetary union) is an intergovernmental agreement that involves two or more states sharing the same currency. These states may not necessarily have any further integration (such as an economic and monetary union, which would have, in addition, a customs union and a single market).

The euro (symbol: €; currency code: EUR) is the official currency of 20 of the 27 member states of the European Union. This group of states is officially known as the euro area or, more commonly, the eurozone. The euro is divided into 100 euro cents.

The currency is also used officially by the institutions of the European Union, by four European microstates that are not EU members, and the British Overseas Territory of Akrotiri and Dhekelia, as well as unilaterally by Montenegro and Kosovo. Outside Europe, a number of special territories of EU members also use the euro as their currency.
