In “The Fiat Standard” Saifedean Ammous defines fiat currency as:

A compulsory implementation of debt-based centralized ledger technology monopolizing financial and monetary services worldwide.

In other words it’s government money, that we have no choice but to use. And instead of being a commodity with some market value in itself, fiat currency itself is based on debt.

The crazy thing is that that every single fiat currency in recorded history has eventually collapsed or been abandoned.

That’s a 100% failure rate, excluding the currently circulating fiat currencies. But they too will fail.

Yet today, society still persists with running the entire global financial system on fiat currencies—money backed by nothing more than government decree and public confidence.

This has had far reaching economic, political and social implications.

In this article, I’ll explore the nature of fiat currency, trace its history, and discuss how this monetary system continues to shape our economic reality.

Understanding the nature of fiat currency is important for the student of monetary history and it helps you better understand Bitcoin and gold. But it is also an incredibly useful practical life skill. When you understand why your savings lose purchasing power over time, you can take protective measures to limit the damage.

The Definition and Core Characteristics of Fiat Currency

The Latin word “fiat” is literally translated into “let it be done.”

The implication there for money is that when a currency can be created by fiat, it can be created by decree.

By contrast hard money, such as precious metals or Bitcoin must be mined at a cost. The supply cannot be increased by a political decision.

Fiat currency has unlimited supply. But more importantly it has no coded supply schedule (like Bitcoin) or estimated annual mine output (like gold). The rate of new supply is largely influenced by policy decisions, making it incredibly difficult for market participants to have any certainty.

Because it isn’t backed by any commodity, nor convertible into any hard asset, the acceptance of fiat currency relies entirely on legal tender laws and—most precariously—public confidence.

The key characteristics that define fiat currency include:

No Intrinsic Value: Intrinsic value is not required for something to become money, the market can assign monetary value to anything. But historically, humans have often gravitated towards things like gold and silver for money partly because they possess some inherent worth. Fiat currency possesses no intrinsic.

Unlimited Supply Potential: New fiat currency units can be created at will, limited primarily by policy and political considerations with no physical constraints. This stands in stark contrast to commodity money or Bitcoin, where increasing the supply requires mining.

Legal Tender Laws: Governments enforce the use of their fiat currencies through legal mandates, requiring citizens to accept them for debt payments and tax obligations. Without these laws, fiat currencies would likely struggle to maintain their monetary status as they would be forced to compete freely against non-governmental hard money alteratives.

Dependence on Confidence: Perhaps most critically, fiat currencies rely on public faith in the issuing government’s stability and the currency’s future purchasing power. This psychological foundation makes fiat systems inherently fragile and subject to rapid collapse when confidence erodes. It may not happen often in developed economies but it happens frequently enough to be a genuine risk.

A Brief History of Money: How Did We End Up With Fiat

To fully understand the nature of our current fiat monetary system, it helps to first examine the evolution of money throughout history. This will help you understand exactly how we arrived at today’s unprecedented experiment in unbacked fiat currency.

The Emergence of Commodity Money

Over millennia, societies independently discovered that certain commodities—cattle, salt, shells, and eventually precious metals—could serve as media of exchange. These items possessed desirable monetary properties: durability, portability, divisibility, and scarcity.

Gold and silver eventually emerged as the ultimate form of commodity money due to their superior properties.

This wasn’t a government decree—it was determined by the market.

The Development of Representative Money

As economies grew more sophisticated and global trade increased, carrying or shipping large quantities of gold became impractical. Banks and governments began issuing certificates or notes redeemable for specific amounts of precious metals.

This was paper money but it was representative money. In other words it maintained the benefits of commodity backing while improving convenience and portability.

However, crucially, the paper money could be fully converted back into gold on demand. This was the era of the gold standard.

The Bretton Woods System: A Transitional Phase

The classical gold standard ended over the period 1914-1933, between the onset of the Great War and the reforms of President Roosevelt.

After World War II, the Bretton Woods Agreement established the U.S. dollar as the world’s reserve currency, backed by gold at $35 per ounce. Other currencies were pegged to the dollar, creating an international gold exchange standard.

This was not a true gold standard but at least gold remained a core pillar of the monetary system.

However, Bretton Woods was a flawed system that did not last. The U.S. government printed dollars beyond its gold reserves, leading other nations to lose confidence in the dollar and demand convertibility of dollars into gold.

1971: The Nixon Shock and the Birth of Pure Fiat

On August 15, 1971, President Nixon temporarily suspended the dollar’s convertibility into gold—a supposedly “temporary” measure that has lasted well over 50 years. This action, known as the Nixon Shock, severed the last link between major world currencies and gold, giving us the era of pure fiat currency, where gold became a reserve asset only.

How Fiat Currency Works in the Modern Economy

Understanding how fiat currency functions in practice will help you understand why it generates such significant economic distortions. Unlike commodity money systems that relied on market forces and physical constraints in its production, fiat systems operate through centralised control and artificial manipulation is easy.

Central Bank Money Creation

At the heart of the fiat system lies the central bank with the power to create new money.

While it is commercial banks that primarily create new currency units though lending, the Federal Reserve can create new dollars though several mechanisms:

Open Market Operations: Purchasing government bonds with newly created money, directly injecting liquidity into the banking system
Discount Window Lending: Providing loans to commercial banks using created-on-demand currency
Quantitative Easing: Large-scale asset purchases that expand the money supply dramatically

The Fractional Reserve Banking Multiplier Effect

Fiat systems amplify central bank money creation through a process called fractional reserve banking. When the Federal Reserve creates $100 and deposits it in a commercial bank, that bank can lend out $90 (keeping 10% as reserves). The borrower deposits this $90 in another bank, which can then lend $81, and so on.

This process, known as the money multiplier effect, can theoretically expand $100 of base money into $1,000 or more of total money supply.

Government Deficit Financing Through Fiat Creation

One of the primary appeals of fiat currency for governments is for deficit financing.

To finance new spending governments could raise taxes or cut spending elsewhere. But for political reasons they don’t like to do that. So instead, they simply issue new bonds and the central bank buys them with newly created money.

This is known as debt monetisation and it allows governments to continually spend beyond their means, creating a stealth tax on savers in the form of inflation.

Interest Rate Manipulation as Policy Tool

Central banks use interest rates as their primary tool for managing fiat currency systems. They can artificially lower rates, in an attempt to encourage borrowing and discourage saving, to stimulate short-term economic activity.

However, this manipulation creates profound distortions. Austrian economics does a wonderful job of explaining how artificially low rates encourage malinvestment—projects that appear profitable only because of subsidised borrowing costs.

When rates eventually rise or economic reality asserts itself, these malinvestments must be liquidated, creating the boom-bust business cycles that characterise fiat economies.

Legal Tender Laws: The Foundation of Fiat Acceptance

The fiat currency system also relies on legal tender laws that require acceptance of government currency for debt payments and tax obligations. These laws, backed by the full force of government, create an artificial demand for otherwise worthless currency.

Without legal tender laws, fiat currencies would face competition from superior sound money alternatives. This coercive aspects reveals the fundamental weakness of fiat currency—it cannot compete in a free market against superior monetary alternatives.

That is why history shows that every time it is tried it fails and society eventually returns to sound money.

The Advantages of Fiat Currency (The Official Narrative)

It is worth taking the time to understand the argument in favour of fiat currency from its proponents.

While these arguments often contain fundamental flaws, understanding the official narrative is necessary for comprehending why governments and central banks defend fiat systems so vigorously.

Monetary Policy Flexibility During Crises

Advocates of fiat argue that it provides flexibility for responding to economic crises. During recessions or financial panics, they claim the ability to rapidly expand the money supply and lower interest rates prevents economic collapse and mass unemployment. For example the 2008 financial crisis and the 2020 Covid pandemic.

This narrative portrays central banks as economic heroes, intervening to save markets and jobs when natural forces would otherwise cause devastation.

The assumption is that the free market is inherently unstable and requires government intervention to function properly.

Economic Growth Stimulation Through Money Creation

A prominent fiat claim is that modest money creation can stimulate economic growth by encouraging investment and consumption. That is why central bankers wants inflation within a target band. No inflation or deflation is an economic ill to them.

The theory suggests that increasing the money supply lowers interest rates, making borrowing more attractive for businesses and consumers.

Lower borrowing costs theoretically encourage:

Business expansion and capital investment
Consumer purchases of homes, cars, and other durables
Increased employment as businesses expand to meet growing demand
Higher asset prices that create “wealth effects” encouraging further spending

This narrative positions money printing as a tool for prosperity rather than the debasement that it really is.

Independence from Physical Commodity Constraints

Proponents argue that fiat systems liberate economies from the “barbarous relic” of gold standards. They claim that linking money to commodities creates artificial constraints that can harm economic growth and employment. The implied argument here is that commodity money is old technology from a bygone age and that a modern economy needs modern money. To central bankers, that modern money is unrestrained fiat.

The narrative suggests that human intelligence, in particular central bank expertise, can manage the currency system better than market forces and the physical contraints of commodity money.

Ease of Digital Transactions and Modern Banking

Modern fiat systems seamlessly integrate with electronic banking, digital payments, and global financial networks. Proponents argue that returning to commodity standards would be impractical in an age of instant global transactions and complex financial instruments.

While the convenience of digital fiat money is undeniable this argument suggests that modern digital technology is incompatible with sound money principles. It is an odd claim since we have never had a sound money system in the digital era, but there is no reason to suggest it would not be possible.

The Hidden Costs and Dangers of Fiat Systems

While all those benefits exist in theory, the reality is that fiat currency imposes profound costs on society, costs that are largely obscured from public understanding.

These hidden consequences, you could argue, are actually the true nature of fiat currency. It is a system of wealth redistribution that benefits the few at the expense of the many and undermines the foundations of a productive and well functioning society.

Inflation: The Invisible Tax

Inflation is the steady erosion of purchasing power that transfers wealth from savers to debtors. As fiat currency is debased those who hold currency bear the full burden of debasement, while those who borrow money to buy assets see the asset rise and the real value of the debt recede.

Unlike direct taxation, which citizens can see and potentially resist though political pressure, inflation operates as a hidden tax that most people don’t fully understand.

Asset Bubbles and Capital Misallocation

The ability of the central bank to create artificially low interest rates results in misollocation of capital in the economy. Interest rates are the price of money and are the most important price signal in the economy. Artificially lowering them encourages investment in projects that would be unprofitable otherwise.

The result is the boom-bust cycle with every crash being followed by more aggressive monetary stimulus, creating larger and larger bubbles. All this is easily explained by Austrian economics for those who care to look.

The Cantillon Effect: How Fiat Currency Increases Wealth Inequality

One of the most insidious aspects of fiat currency is the Cantillon effect—the unequal distribution of new money throughout the economy.

When new units of fiat currency are created, it doesn’t appear simultaneously in everyone’s pockets at the same time. Instead, it flows first to banks, large corporations, and government contractors before slowly reaching ordinary citizens through wages and consumer spending.

The first to receive the money can spend it before the increase in currency supply has flowed through to prices. By the time new money reaches average workers, prices have already risen to reflect the increased money supply. In a wage-price spiral, wages are always catching up to prices and the average worker becomes worse off.

In essence this is a systematic wealth transfer from the productive economy to the financial sector and politically connected industries. Wall Street benefits from asset price inflation while Main Street suffers from consumer price inflation. The result is the growing wealth inequality.

Time Preference Distortion and Societal Decay

Perhaps most fundamentally, fiat currency corrupts the natural human tendency to save for the future. This is something Saifedean Ammous explains very well in The Fiat Standard.

Sound money encourages low time preference—the willingness to sacrifice present consumption for future benefit. This trait enables capital accumulation, technological progress, and civilizational advance.

Fiat currency’s constant depreciation punishes saving and rewards consumption and speculation. Why save money that loses value when you can either spend it now or borrow cheap fiat currency to buy appreciating assets? This high time preference mentality undermines the patient capital accumulation that built modern civilization.

The social consequences extend far beyond economics. When people cannot reliably save for the future, family formation becomes more difficult, long-term planning becomes irrational, and society becomes increasingly focused on immediate gratification rather than sustainable development. Ammous argues this represents nothing less than the systematic destruction of the psychological foundations of human civilization.

Historical Examples of Fiat Currency Failures

So far we have only discussed the theoretical problems with fiat currency. However when you check the history books, this theory becomes a stark reality.

Every fiat currency experiment in recorded history has ended in failure—either through hyperinflation, formal abandonment, or replacement with sound money.

These cases provide crucial lessons about the inherent instability of fiat currencies and provide a warning about the inevitable collapse of our current system.

Weimar Germany: The Textbook Hyperinflation Case Study

The Weimar Republic’s hyperinflation of 1921-1923 is the most famous example of fiat currency collapse. After World War I, Germany faced massive reparation payments to Allied nations while dealing with economic devastation and political instability.

Rather than raise taxes or cut spending—both politically impossible—the German government chose to print money to meet its obligations.

The consequences were devastating. Middle-class savings evaporated overnight. Workers demanded to be paid twice daily because prices rose faster than wages. Citizens used wheelbarrows to carry cash for basic purchases. The entire social structure collapsed as money became worthless.

The Weimar hyperinflation destroyed the economic foundation of German society and contributed directly to the political extremism that followed. The case demonstrates how quickly fiat currency can spiral out of control once confidence erodes—and the terrible social costs of monetary collapse.

Zimbabwe: Modern Hyperinflation in the 21st Century

Zimbabwe’s currency collapse from 2000-2009 proves that hyperinflation isn’t just a historical curiosity—it can happen to any nation that abuses fiat currency printing. Under President Robert Mugabe’s policies, Zimbabwe’s government printed money to fund land redistributions, government spending, and a military conflict in the Democratic Republic of the Congo.

The hyperinflation peaked in 2008 when prices doubled every day. Zimbabwe issued a 100 trillion dollar note that couldn’t buy a loaf of bread. The official inflation rate reached 231 million percent annually, though outside estimates suggested a figure much higher.

Citizens abandoned the Zimbabwe dollar entirely, turning to foreign currencies, gold, and barter systems. The government was forced to officially abandon its own currency in 2009—a complete admission of failure. Even today, Zimbabwe struggles with the economic and social consequences of its monetary collapse.

The Zimbabwe case is particularly relevant because it occurred in the modern era with access to international markets and financial expertise. Yet the government still chose money printing over fiscal discipline, demonstrating the political incentives that cause fiat currency abuse.

Venezuela: Recent Socialist Hyperinflation

Venezuela’s current hyperinflation provides a real-time example of fiat currency destruction. Once Latin America’s wealthiest nation due to oil revenues, Venezuela began aggressive money printing under socialist policies starting in the early 2000s.

The bolivar has lost over 99% of its value since 2013. Millions of Venezuelans have fled their country, basic goods are unavailable, and social order has largely collapsed.

Venezuelan citizens have increasingly turned to U.S. dollars, gold, and even bitcoin to preserve wealth and conduct commerce. The case demonstrates how market forces eventually reject failed fiat currencies, regardless of government mandates or legal tender laws.

Common Patterns in Fiat Currency Failures

These historical examples reveal consistent patterns in fiat currency collapse:

Initial Success: Early adoption appears beneficial as governments gain flexibility
Gradual Abuse: Printing gradually increases to fund popular programs – leaders think they be able to show restraint
Acceleration Phase: Economic problems lead to more aggressive money printing
Confidence Crisis: Citizens begin rejecting the currency for alternatives
Hyperinflation: Rapid currency collapse as confidence disappears entirely
Abandonment: Government forced to adopt foreign currency or return to commodity money

The lesson is clear: every fiat currency eventually fails because the political incentives that create these systems inevitably lead to their destruction. No amount of economic expertise or good management can overcome the fundamental problem—fiat currency gives governments the power to siphon wealth from their citizens through monetary manipulation, and that power will always eventually be abused.

Protecting Yourself in a Fiat Currency World

While understanding the problems with fiat currency systems is essential, translating this knowledge into practical protection strategies is equally important.

Living in a fiat system requires certain defensive measures that would be unnecessary if we had sound money. As Saifedean Ammous explains, sadly the fiat system forces everyone to engage in monetary speculation just to preserve their purchasing power.

Asset Allocation Strategies for Currency Debasement

Traditional financial advice assumes stable purchasing power and focuses on balancing risk and return within conventional asset classes. Under fiat currency systems, this approach guarantees long-term wealth destruction because conventional “safe” assets like bonds and cash deposits systemtically lose purchasing power.

While the government likes to tell us inflation is around 2%, many argue that the actual figure is closer to 7%. That becomes the hurdle rate you have to clear before you are making a real rate of return.

Conservative investments just don’t cut it.

Precious Metals

Gold and silver have been the most reliable protection against fiat currency debasement for centuries. Precious metals offer several crucial advantages:

No Counterparty Risk: Physical metals don’t depend on any institution’s solvency or promises
Historical Reliability: Gold has preserved wealth through every fiat currency collapse in history
Government Resistance: While governments can manipulate paper markets, they cannot create gold
Global Acceptance: Precious metals are recognized and accepted worldwide
Crisis Performance: Gold typically performs best during periods of monetary and political instability

While monetary systems come and go, precious metals have always endured and are what people have always turned to in times of financial turmoil.

Precious metals are not investments per se, rather they are best seen as politically neutral historical forms of sound money. They are designed to preserve your purchasing power when the value of fiat currency declines.

Real Estate

Real estate historically provides inflation protection because property values typically rise with currency debasement. Land is a scarce asset and has been a wealth storage vehicle since the beginning of civilization.

Many people over the last 50 years have protected themselves and become very wealthy through borrowing cheap fiat to buy land. This has worked very well since the 1980s as long term interest rates have trended downward.

However, modern real estate investment does also carry significant risks, so it is not just as simple as buying land and forgetting about it. There are property taxes, maintenance costs, regulatory risks and the ever present risk of a real estate bubble.

Stocks

Stocks can provide inflation protection because profitable companies can raise prices to maintain profit margins. If you buy the index you can reasonably hope to get inflation protection and perhaps some real growth over a long period of time.

If you have the skills to select companies that benefit from inflation and have the technical analysis skills to consistently buy low, sell high then equities can be an effective vehicle for the protection of wealth.

Bitcoin

Bitcoin is a return to sound money principles but through a disruptive technological innovation rather than political reform. Its fixed supply and decentralized nature provides protection against fiat currency debasement.

And, at least for now, it offers massive upside potential as early owners capture the speculative gains of new technoligcal adoption.

Bitcoin should be considered a speculative allocation within a broader sound money strategy rather than a complete solution to fiat currency problems. Its long-term potential is enormous, but short-term risks make it unsuitable for funds needed within several years.

Conclusion

Understanding fiat currency isn’t just an academic exercise—it’s essential knowledge for anyone who wants to protect their wealth and understand the economic forces shaping our world. Throughout history, societies that abandoned sound money principles have faced the inevitable consequences: inflation, economic instability, and eventual monetary collapse.

The 100% failure rate of fiat currencies throughout history isn’t coincidence—it’s the inevitable result of removing market discipline from money creation. Every example shows a consistent pattern: governments inevitably abuse the power to create money, leading to economic destruction and social collapse.

What makes our current situation particularly dangerous is its global scope. Previous fiat currency failures remained largely regional, allowing people to escape to sound money alternatives. Today’s coordinated fiat system affects virtually the entire world, making avoiding the fiat collapse more difficult.

Luckily there is an escape hatch called Bitcoin.
