A fiat currency is a currency that is not backed by any physical commodity such as gold or silver, instead it is just the money issued by the government. The value of the Fiat currency is mainly derived from the trust and authority of the issuing government. In the modern world, most paper currencies, including the Indian Rupee (INR), the U.S. Dollar (USD), Euro (EUR), Japanese Yen, Chinese Yuan, are just the fiat currencies.
Features of a fiat currency
- No intrinsic value: The fiat currency does not have an inherent value, that is, it does not have intrinsic value per se. It cannot be redeemed for a fixed amount of any commodity
- Legal tender: A fiat currency is declared, by the government, as a legal tender in a country and thus it must be accepted for all sorts of payment
- Unlimited supply: The Central Bank of a country can print or withdraw fiat currency based on its Monetary Policy needs. Thus, a country can print more number of fiat currencies (Note: This leads to hyperinflation)
- Value based on demand and supply: The purchasing power of a fiat currency depends on several macroeconomic variables like inflation, interest rates and the stability of the economy
Paradigm shift from commodity money to fiat money
Prior to the introduction of fiat money, most currencies in the world were backed by physical commodities like gold and silver. That is, under the Gold Standard, paper notes could be exchanged for a certain amount of gold. However, in later stages, several countries started abandoning the Gold Standard system during the 20th century. The major turning point was in 1971, when the United States ended dollar convertibility to gold, thus, the world was effectively transitioned into a fiat-based system.
How does the fiat currency work?
A Fiat currency is issued by the Central Bank of a country. Say for instance, the Reserve Bank in India and the Federal Reserve in the U.S. The fiat money is circulated in the economy through the country’s banking/financial system. It is used for: day-to-day transactions, repaying debts, savings, investments, accounting, pricing and all other monetary purposes. The supply of the fiat currency is controlled by the Central Bank of the country through its Monetary Policy tools like interest rates, reserve requirements etc. These tools have a great impact on inflation, liquidity and the overall economic growth/contraction of the country.
Advantages of fiat currency
- Monetary flexibility: Since the notes are printed by the Central Bank of the country, it allows the Central Banks to adjust money supply in the economy so as to meet its economic objectives like growth, inflation control, employment etc
- Cost-efficient: When compared to commodity-based money such as gold and silver, which must be mined and processed, producing fiat currency is cheaper and cost effective
- Responsive to economic needs: The Central Bank may expand or contract the supply of the fiat currency depending up on the economic needs of the country. Say for instance, government could print more currency, as a stimulus, during crisis period like COVID-19 pandemic
Disadvantages and risks
- Inflation/Hyperinflation: Excessive printing of fiat currency will erode the purchasing power of the money, that is, money loses its value (e.g., Zimbabwe, Venezuela suffered from hyperinflation due to printing of money)
- Dependency on trust: The value of the fiat currency purely depends on the trust/confidence the people have in the issuing government and the Central Bank. Less trust, less value
- No intrinsic protection: Unlike commodity money like gold or silver, fiat currency does not have intrinsic value (in itself) and therefore, there is no protection against mismanagement
Fiat currency in India
In India, the Central Bank – Reserve Bank of India (RBI) – takes up the sole responsibility of issuing the fiat currency under the provisions of the RBI Act, 1934. The Indian Rupee (INR) is a fiat currency and a legal tender in the country, and it is accepted for all kinds of transactions within the country. It is backed by the trust and confidence in the Government of India. As per the RBI’s annual report 2024-2025, the banknotes in circulation were approximately more than ₹36 lakh crore.
