What Is Fiat Currency and How Does It Work?

Fiat currency is a form of legal tender whose value is derived from the government that issues it, not a physical commodity. This system replaced the gold standard and other commodity-based systems as a means of determining the value of the legal tender. While there are pros and cons to using fiat currency, the rise of cryptocurrencies like Bitcoin has created a new financial landscape that challenges the traditional system. As the crypto market continues to mature, Bitcoin and other cryptocurrencies may one day overcome fiat currencies altogether.


The modern monetary system relies on fiat currency, which is a form of legal tender that derives its value from the government that issues it rather than a physical commodity. The government's strength is crucial to the value of this currency, and it is widely used for transactions, investments, and savings worldwide. This system replaced the gold standard and other commodity-based systems as a means of determining the value of the legal tender.

History of Fiat Currency

Paper money, which is the precursor of modern-day fiat currency, was first issued in China's Szechuan province during the 11th century. The currency's value was initially backed by silk, gold, and silver. However, during the 13th century, Kublai Khan came to power, and he established a fiat currency system. This system is said to have contributed to the downfall of the Mongol Empire, as excessive spending and hyperinflation led to its decline.

Several European countries, including Spain, Sweden, and the Netherlands, adopted the fiat currency system in the 17th century. The system was unsuccessful in Sweden, and the government eventually switched to the silver standard. Over the next two centuries, fiat money was experimented with in New France, the American Colonies, and eventually the U.S. Federal Government, with varying degrees of success.

In the 20th century, the U.S. briefly returned to a commodity-based currency system, but this was short-lived. In 1933, paper money could no longer be exchanged for gold. And by 1972, under President Nixon, the U.S. abandoned the gold standard altogether, ending it on an international scale and fully embracing the fiat currency system. This paved the way for the use of fiat currency worldwide.

Fiat Currency vs. The Gold Standard

Under the gold standard, paper bills could be converted to gold, with all paper money backed by a finite amount of gold held by the government. This limited the government's ability to create money or increase the value of its currency based solely on economic factors.

In contrast, under the fiat currency system, money is not backed by anything and authorities can directly impact the value of their currency based on economic conditions. Governments and central banks have more control over currency systems and can respond to financial events and crises using various tools like fractional reserve banking and quantitative easing.

Proponents of the gold standard argue that a commodity-based currency system is more stable because it is backed by something physical and valuable. However, fiat currency supporters argue that gold prices have been historically unstable. Ultimately, the value of both commodity-based currency and fiat money can fluctuate, but with a fiat currency system, the government has more flexibility to act during economic emergencies.

Pros and Cons of Using Fiat Currency

There is no clear consensus among economists and financial experts regarding the benefits of fiat currency. Supporters and opponents of this currency system passionately debate its pros and cons.

Pros of Using Fiat Currency

  • Flexibility: Governments can respond to economic emergencies quickly and have greater control over the currency system.
  • No need for a commodity: Fiat currency is not tied to any physical commodity, which allows for more flexibility and adaptability in the global economy.
  • Reduced transaction costs: Fiat currency eliminates the need for physical commodities, reducing the transaction costs associated with commodity-based currency systems.
  • Uniformity: Fiat currency is standardized and easily recognizable, making it easier to use in transactions and reducing the risk of counterfeiting.
  • Stability: Fiat currency is generally more stable than commodity-based currency systems, which can fluctuate wildly in value.

Cons of Using Fiat Currency

  • Inflation: Without a physical commodity backing the currency, fiat currency can be subject to inflationary pressures.
  • Depreciation: Fiat currency can depreciate over time, leading to a loss of purchasing power for consumers.
  • Vulnerability to political instability: Fiat currency is tied to the stability of the issuing government, and political instability can lead to a loss of confidence in the currency.
  • Centralized control: Fiat currency is subject to centralized control by governments and central banks, which some individuals may view as negative.
  • Potential for abuse: Fiat currency systems can be abused by governments and central banks to manipulate the economy or pursue political agendas.

Fiat Currency vs. Cryptocurrency

Cryptocurrencies and fiat currency share only one similarity: neither is backed by a physical commodity. However, cryptocurrencies differ from fiat currency in that they are decentralized, thanks to the distributed digital ledger known as Blockchain. While banks can create fiat money based on their assessment of economic needs, cryptocurrencies have a limited and controlled supply, like Bitcoin.

Being digital, cryptocurrencies are borderless and offer fewer restrictions on global transactions, making them irreversibly traceable. However, tracking cryptocurrencies is significantly more challenging than fiat currency.

The crypto market is smaller and therefore more volatile than traditional markets, which is likely why cryptocurrencies have yet to achieve universal acceptance. However, as the crypto economy matures, it is expected that volatility will diminish.


While fiat currencies have been the backbone of the global economy for centuries, the rise of cryptocurrencies like Bitcoin has created a new financial landscape. Bitcoin's decentralized nature, limited supply, and irreversibly traceable transactions make it an attractive alternative to traditional fiat currencies, particularly in the face of political instability and centralized control. As the crypto market continues to mature, Bitcoin and other cryptocurrencies may one day overcome fiat currencies altogether. However, it remains to be seen whether the benefits of a cryptocurrency-based financial system will outweigh the drawbacks and whether governments and central banks will be willing to give up their centralized control over the money supply.
