What is Currency History evolution and national currencies


Currency is a means of exchanging goods and services. In short, it is money, in the form of paper or coins, usually issued by a government and generally accepted at face value as a method of payment.

It is the primary medium of exchange in the modern world, having long since replaced barter as the means of trading goods and services.

In the 21st century, a new form of it entered the vocabulary, the virtual currency. Virtual currencies, like Bitcoins, have no physical existence or government backing and are traded and stored in electronic form.

History and evolution of the currency

The origin dates back to the first civilizations of merchants, in Asia Minor and Babylonia as a way of valuing the consideration received from merchandise traffic. Thus, as history teaches us, once barter is no longer used as the main form of exchange, currency becomes important because it creates an instrument of value with which to quantify goods and services.

So much so, that during most of their history, coins have been pure precious metals, such as gold, silver, bronze… Thus creating a direct way of valuing merchandise with respect to the base valuation elements. as are precious metals. This is what is known as intrinsic value. The currency is worth because it is composed of some precious metal, which is really what has value.

The meaning of currency

Subsequently, the meaning has been changing. At the same time that commercial exchanges grew globally, precious metals became scarce, so in the 19th century a new way of creating money originated, associating coins of other metals with no value of their own to gold and silver reserves. Being the currency endorsed by the assets that had made up the money until then.

Thus, before this system, a coin corresponded to a certain quantity (grams) of gold or silver, while during this system what was attempted was an equivalence between assets. For example, that a 3 English pound coin corresponded to half a kilo of gold, or similar in Spain, where 10 pesetas corresponded to a certain amount of gold as well. That is, it is worth because it has a true counterpart in precious metals.

For several decades, we have had another currency valuation system, which corresponds to the value that people give to that currency, without being anchored to precious metals or other forms of valuation. It is what is called fiduciary money , that is, that currency that does not have any precious asset as a counterpart, but is based on the trust and good faith that people (all agents) deposit in it.

For example, a large part of the world’s currencies, which have their value not because they are made up of precious metals, or indicate an indirect possession of them, but rather we adopt and give confidence that it is worth what it really says it is worth, facilitating the exchange of goods and services.

A one euro coin is not really worth one euro, since its materials are worth less, however we give it the category that is worth that, based on the confidence and acceptance of the indicated value.
