Fiat money means fiduciary money. It is a paper which transfers the value from person to person for some goods or services. The value of the paper money is contractual. In a fiat money system money is not secured by a physical commodity. Instead, the only thing that gives money value is its relative scarcity and the fact that people want it. One way to explain the value of fiat money is through debt. If you are in debt, you have no choice but to try and get some pieces of paper to pay off your debt, and if the paper is short, you have to fight for it. Interestingly, debt seems to go hand in hand with fiat money.

In other words, fiduciary money is a legal tender whose value is determined and obtained by the government that issues it, not from a physical good or good. The government forces that determine the value of monetary data in money are crucial for this type of money. Most countries around the world use the currency system to buy goods, services, invest and save. The Fiat currency has replaced gold and other commodity systems that used to be used for valuation.

FIAT (Fiduciary Money )- the name derives from the Latin term "fides" translated as "faith". It is a currency that is not based on material goods, and its value is usually governed by the decreed monopoly right to use it as legal tender. The value of fiduciary money is also determined by the demand that is controlled by state institutions (e.g., through the collection of taxes). 

The name fiduciary money refers to the fact that its value is based on trust towards the issuer. 

Currently, the issuer of the fiduciary money is the central bank, which conducts the monetary policy of a given state. What is more, the amount of money introduced into circulation is conditioned by, among others, the current interest rate of credits granted by the central bank.

Fiduciary money is a legal tender, the value of which is not guaranteed by material goods such as silver or gold, but by a legal act issued by the state and trust in the issuer (the entity issuing the money). This currency can be recognized by several characteristic features:

The fiduciary money is issued by a monopolist - it is usually the central bank of a given country;
The demand for the currency is ensured by state institutions - the circulation of fiduciary money is guaranteed by systems created by the state - an example is the tax system, which forces the payer to settle taxes in the national currency;
currency takes the form of banknotes or coins - it is worth mentioning that coins and paper money cannot be made of materials whose value would be higher than the face value of the currency.

Fiat money is the money we use every day to pay in shops or for services. Fiat money means trusting a bank that it has this amount of money in deposit. The value of fiat money is determined by convention by people.

FIAT-Geld ist eine Währung, die nur einen gesetzlichen Wert hat, der von der Regierung festgelegt wird, die sie emittiert hat. Im Gegensatz zu Rohstoffgeld, das einen inneren Wert hat, hat FIAT-Geld nur einen Wert, weil Regierungen ihn als gesetzliches Zahlungsmittel akzeptieren. In der modernen Wirtschaft spielt FIAT-Geld eine wichtige Rolle beim Austausch von Waren und Dienstleistungen sowie bei der Speicherung von Wert.
