What is a fiat currency?

Since Bitcoin came into existence in 2009, the use of the term fiat currency has significantly increased. But what is a fiat currency? In this article, we take a look at the origins of the term and why it's called fiat currency, how it functions, some examples of fiat, and what threat crypto has posed to it. Let’s dive in. 

What is fiat money?

Fiat money is money declared as legal tender by the government and acts as a nation's currency. The term "fiat" is a Latin word and loosely translates to "by decree" which is an authoritative order with the force of law. The government declares fiat money legal tender by decree. 

Fiat money acts as a national currency and is printed by the government. Citizens can use it for payments of goods and services, facilitating trade in the area. 

In 2020, all currency traded internationally was officially declared as fiat money. This means that the value of fiat money isn't linked to anything physical like gold or silver but rather to the faith and credit of that government. All fiat currencies are operated by a central authority, in most cases central banks, that carry out a nation's monetary policy and are responsible for controlling its money supply.

Until 1971, foreign currencies were fixed in value relative to the US dollar whose worth was based on an amount set by Congress expressed in terms of gold ounces. That year President Richard Nixon did away with that system completely in what was called  "the Nixon shock." 

Fiat currency vs fiat money

Fiat currency and fiat money essentially refer to the same thing. Both represent the government-issued currency used in a country or region. There are around 180 different types of fiat currencies in use globally. Examples of fiat include the United States dollar, Canadian dollar, Euro, and British pound sterling, or Japanese yen. 

The value of one fiat currency in relation to another is referred to as the exchange rate.

Fiat money vs commodity money

Fiat money is essentially the opposite of commodity money. The major difference between the two stems from their intrinsic value. In general, a commodity currency has an intrinsic value that comes from what it is made of, a physical commodity such as gold or silver coins.

Fiat currency does not have any intrinsic value and only exists because a country's government or country's central bank says it can be exchanged for other goods with equal value.

How did fiat currencies come into existence?

All money is a certificate of debt. In the past, if someone needed to be paid back for something at a later date, they would receive an IOU that said how much was owed to them and when it could be collected. 

Bartering system

For example, let's say a farmer traded 2kg of flour today for ten pumpkins come harvest time. 

To keep track of this arrangement and to avoid forgetting or getting confused about what was owed, the person providing the flour would be given a piece of paper indicating that it could be exchanged for pumpkins after harvest. This piece of paper effectively becomes worth ten pumpkins and could be used to trade for milk, bread, or any other goods. 

The bartering system only allowed trade to happen when each person had what the other one desired. To make it more efficient, people started using something that everyone wanted as a basis for trading, a physical commodity. For a long time, rocks that shine (gold) served that purpose.

Gold to coins

However, weighing gold for each transaction was complicated, so governments started to create identical gold coins made from a specific amount of gold. They put raised lines around the edge of every coin as proof that no one shaved off any bits of gold, making trade easier since everyone knew how much each currency was worth.

Introduction of banks

However, gold is heavy to carry and became dangerous to keep on oneself at all times, so people started storing their gold in bank vaults. Bankers would provide a certificate as proof that each person owned a certain amount of gold, which could later be redeemed at the central banks for gold. This shifted the legal tender from gold to a piece of paper. 

Gold to paper money

As the government was typically the largest holder of gold, it began printing its own paper currency that people could use to trade for gold at the national treasury, representing the origins of the gold standard. However, people stopped going to redeem the paper for gold and instead just used the paper itself. 

Supply/demand logistics

At this stage, a currency's value was still tied to the value of gold, which had some problems in itself. Firstly, if a new source of gold emerged or another country suddenly released a significant amount of gold, the currency's value would drop. Secondly, anyone could manipulate the price of gold thereby throwing the currency's value. 

Fiat money emerges

Hence, the gold standard was dropped in the 1930s. Instead, the currency became worth the amount printed on the piece of paper instead of the gold it represented. IOUs once again became the official source of money and held value "by decree" instead of based on an underlying asset. 

Is fiat money still relevant today?

Since the advent of cryptocurrencies (digital currencies not managed by a central authority or government), the way we think about money has changed significantly. While mainstream adoption of these digital currencies continues to grow (several countries have declared Bitcoin as a legal tender) the use of fiat money isn't going anywhere. 

Fiat currencies still hold a significant place in the global economy and will continue to do so for a long, long time. And while some grow skeptical of governments' power to mint new fiat money or the central banking system in general, it's unlikely that fiat currencies are going anywhere. 

CBDCs

One new development that is gaining popularity is the CBDC, merging the worlds of fiat currency with digital currencies. The Central Bank Digital Currency is maintained and operated by central banks, uses blockchain technology to operate, is pegged to the value of the local fiat currency, and works in parallel to the national currency. Eradicating price volatility, the CBDC uses a more secure means of distributing and facilitating the movement of fiat currency. 

While cryptocurrencies are unlikely to replace fiat currencies anytime soon, it's worth noting how significantly the concept of money has changed over the last century and considering how things could change in the future for fiat currency as we know it.
