Coinage

The prevalence of metal coins possibly led to the metal itself being the store of value: first copper, then both silver and gold, and at one point also bronze. Today other non-precious metals are used for coins. Metals were mined, weighed, and stamped into coins. This was to assure the individual accepting the coin that he was getting a certain known weight of precious metal. Coins could be counterfeited, but the existence of standard coins also created a new

). Most major economies using coinage had several tiers of coins of different values, made of copper, silver, and gold. Gold coins were the most valuable and were used for large purchases, payment of the military, and backing of state activities. Units of account were often defined as the value of a particular type of gold coin. Silver coins were used for midsized transactions, and sometimes also defined a unit of account, while coins of copper or silver, or some mixture of them (see

The printing of paper money was also associated with wars, and financing of wars, and therefore regarded as part of maintaining a standing army. For these reasons, paper currency was held in suspicion and hostility in Europe and America. It was also addictive since the speculative profits of trade and capital creation were quite large.

This power was delegated to Congress in order to establish and preserve a uniform standard of value and to insure a singular monetary system for all purchases and debts in the United States, public and private. Along with the power to coin money, the United States Congress has the concurrent power to restrain the circulation of money which is not issued under its own authority in order to protect and preserve the constitutional currency.

Currency convertibility

Subject to variation around the world, local currency can be converted to another currency or vice versa with or without central bank/government intervention. Such conversions take place in the foreign exchange market. Based on the above restrictions or free and readily conversion features, currencies are classified as: ; Fully convertible: When there are no restrictions or limitations on the amount of currency that can be traded on the international market, and the government does not artificially impose a fixed value or minimum value on the currency in international trade. The US dollar is one of the main fully convertible currencies. ; Partially convertible: Central banks control international investments flowing into and out of a country. While most domestic transactions are handled without any special requirements, there are significant restrictions on international investing, and special approval is often required in order to convert into other currencies. The Indian rupee and the renminbi are examples of partially convertible currencies. ; Nonconvertible: A government neither participates in the international currency market nor allows the conversion of its currency by individuals or companies. These currencies are also known as ''blocked'', e.g. the
North Korean won The Korean People's won, sometimes known as the North Korean won (Symbol: ₩; Code: KPW; Korean: ) or Democratic People's Republic of Korea won ( Korean: ), is the official currency of North Korea. It is subdivided into 100 ''chon''. The cur ...

, capital flows and national policies, the supply-demand relationship of different currencies determines the exchange ratio between currencies.

are not the only reason affecting the exchange rate. The large number of international tourists and overseas students has resulted in the flow of services and goods at home and abroad. It also represents that the competitiveness of global goods and services directly affects the change of international exchange rates. Capital flows National currencies will be traded on international markets for investment purposes. Investment opportunities in each country attract other countries into investment programs, so that these foreign currencies become the reserves of the central banks of each country. The exchange rate mechanism, in which currencies are quoted continuously between countries, is based on foreign exchange markets in which currencies are invested by individuals and traded or speculated by central banks and investment institutions. In addition, changes in interest rates, capital market fluctuations and changes in investment opportunities will affect the global capital inflows and outflows of countries around the world, and exchange rates will fluctuate accordingly. National policies The country's foreign trade, monetary and fiscal policies affect the exchange rate fluctuations. Foreign trade includes policies such as tariffs and import standards for commodity exports. The impact of

on the total amount and yield of money directly determines the changes in the international exchange rate. Fiscal policies, such as transfer payments, taxation ratios, and other factors, dominate the profitability of capital and economic development, and the ratio of national debt issuance to deficit determines the repayment capacity and credit rating of the country. Such policies determine the mechanism of linking domestic and foreign currencies and therefore have a significant impact on the generation of exchange rates. Currency convertibility is closely linked to economic development and finance. There are strict conditions for countries to achieve currency convertibility, which is a good way for countries to improve their economies. The currencies of some countries or regions in the world are freely convertible, such as the US dollar, Australian dollar and Japanese yen. The requirements for currency convertibility can be roughly divided into four parts: ; Sound microeconomic agency With a freely convertible currency, domestic firms will have to compete fiercely with their foreign counterparts. The development of competition among them will affect the implementation effect of currency convertibility. In addition, microeconomics is a prerequisite for macroeconomic conditions. ; The macroeconomic situation and policies are stable Since currency convertibility is the cross-border flow of goods and capital, it will have an impact on the macro economy. This requires that the national economy be in a normal and orderly state, that is, there is no serious inflation and economic overheating. In addition, the government should use macro policies to make mature adjustments to deal with the impact of currency exchange on the economy. ; A reasonable and open economy The maintainability of international balance of payments is the main performance of reasonable economic structure. Currency convertibility not only causes difficulties in the sustainability of international balance of payments but also affects the government's direct control over international economic transactions. To eliminate the foreign exchange shortage, the government needs adequate international reserves. ; Appropriate exchange rate regime and level The level of exchange rate is an important factor in maintaining exchange rate stability, both before and after currency convertibility. The exchange rate of freely convertible currency is too high or too low, which can easily trigger speculation and undermine the stability of macroeconomic and financial markets. Therefore, to maintain the level of exchange rate, a proper exchange rate regime is crucial.


Local currency

In economics, a local currency is a currency not backed by a national government and intended to trade only in a small area. Advocates such as
Jane Jacobs Jane Jacobs (''née'' Butzner; 4 May 1916 – 25 April 2006) was an American-Canadian journalist, author, theorist, and activist who influenced urban studies, sociology, and economics. Her book '' The Death and Life of Great American Cities ...
argue that this enables an economically depressed region to pull itself up, by giving the people living there a medium of exchange that they can use to exchange services and locally produced goods (in a broader sense, this is the original purpose of all money). Opponents of this concept argue that local currency creates a barrier that can interfere with

. Local currencies can also come into being when there is economic turmoil involving the national currency. An example of this is the Argentinian economic crisis of 2002 in which IOUs issued by local governments quickly took on some of the characteristics of local currencies. One of the best examples of a local currency is the original LETS currency, founded on Vancouver Island in the early 1980s. In 1982, the Canadian Central Bank’s lending rates ran up to 14% which drove chartered bank lending rates as high as 19%. The resulting currency and credit scarcity left island residents with few options other than to create a local currency.
