The European Central Bank has reported: inflation in the eurozone has escalated to 3% in April 2026, reaching its highest level since 2023. You have surely noticed it when paying for groceries or reviewing your bills. However, behind this percentage there is a fundamental reality that very few people truly understand: how fiat money works and why its real value is never guaranteed.
The word fiat comes from Latin and means “let it be done” or “by decree.” When you use euros, dollars, pounds, or yen, you are not using money that is worth something by itself. Unlike the old gold standard, where each bill was equivalent to a portion of precious metal, fiat money is a currency issued by a government whose only backing is trust. Trust in the stability of the issuer, in its laws, and that the rest of society will continue accepting those paper notes or digits on a screen to buy and sell.
This system grants central banks absolute power: to regulate the money supply, set interest rates, and, fundamentally, to print or create money out of nothing. And here is where the inflation trap appears.
The economic rule is mathematical: if the amount of money in circulation increases at a much faster rate than the real goods and services the economy produces, each individual bill becomes worth less.
Fiat money is, by its very nature, especially vulnerable to this phenomenon. Since there is no physical limit to restrain its creation, governments resort to issuing liquidity to finance debts or manage crises. The direct consequence is paid by you through a constant loss of purchasing power. Inflation is not that things become more expensive; it is that your money is silently devaluing year after year.
Saving under the rules of the traditional game no longer works as it used to. Keeping money static in a system designed to progressively lose value means accepting, without voting, an invisible tax that reduces what you can buy with the effort of your work.
The origin of the problem: how fiat money was born
Until 1971, the global financial system was governed by the gold standard. The US dollar, the world’s reference currency, was backed by this precious metal; each bill in circulation was not a simple piece of paper, but a certificate representing a real, physical, and tangible quantity of gold safeguarded in vaults.
However, on August 15, 1971, the then President of the United States, Richard Nixon, unilaterally broke that link by suspending the convertibility of the dollar into gold.
From that moment on, money changed its nature forever: it ceased to depend on a physical and limited resource. From that break onward, money exists solely and exclusively because governments so decree, sustaining its value only in the authority of the State and in the trust of the people.
Why is fiat money issued?
The elimination of the gold backing gives governments the flexibility to manage the economy dynamically. Its main reasons are:

Reason for issuance |
What is it for? |
| Economic control | Allows regulating the amount of money to influence inflation and interest rates. |
| Political flexibility | Money creation is not limited by the physical reserves of a raw material. |
| Facilitating trade | Offers a common medium of exchange that eliminates the obstacles of barter. |
| Stability and trust | A currency backed by a strong government encourages its widespread use. |
| Financing the government | Allows funding public services and infrastructure without relying solely on taxes. |
| Monetary sovereignty | Ensures that the State makes economic decisions without external interference. |
| Crisis management | Allows injecting emergency liquidity (quantitative easing) during recessions. |
How central banks create money out of nothing
In the fiat system, central banks have the absolute power to issue more money when they deem it necessary, without needing to be backed by gold or any physical good. Today, this process does not require turning on the printing presses; it is done digitally through a simple electronic entry in their balance sheets. The process is executed mainly through three key steps:
- Asset purchases (Quantitative Easing or QE):The central bank decides to buy government debt bonds or financial securities held by commercial banks.
- Digital creation:To pay for those bonds, the central bank generates new money digitally on its balance sheet and deposits it into the accounts that commercial banks hold within the central bank itself.
- The multiplier effect:With these new digital reserves in their hands, private commercial banks grant more credits and loans to companies and citizens, multiplying the money in circulation within the real economy.
Now, this power to issue money unlimitedly has a direct and daily impact on people’s pockets:
- The invisible tax of inflation:With more money chasing the same amount of goods and services, the value of each monetary unit decreases. Money is diluted.
- Less purchasing power:When the central bank abuses this mechanism and injects too much liquidity, the prices of food, housing, and services rise. As a result, the average citizen needs more bills to buy exactly the same things, destroying their savings capacity and reducing their quality of life.
Inflation as a symptom of fiat money
Inflation is not a financial accident nor an unpredictable phenomenon; it is a structural characteristic of fiat money. By having no physical limit nor being backed by a finite asset like gold, central banks can constantly expand the money supply. When the amount of money in circulation grows faster than the real production of goods and services, the value of each bill decreases and prices inevitably rise. Money is diluted.
Truly, this problem is not theoretical; it happens on a daily basis. As a reflection of the constant pressure in modern fiat systems, inflation in the eurozone stood at 3% in April 2026. The main driver of this increase was the energy sector, whose prices soared by 10.9%, directly making production, transportation, and the cost of living more expensive for citizens.
So, when governments lose control of the printing press to finance their deficits, the symptom of inflation becomes a mortal disease for the economy.
The most emblematic historical example is the German hyperinflation of the 1920s (Weimar Republic) . During that period, the German mark lost so much value that the government issued bills worth trillions of marks. Prices doubled every few hours and money became so worthless that citizens used it to light fires or as wallpaper, demonstrating the final destination of a fiat currency when trust in it is completely destroyed.
Advantages and limitations of the fiat system
The current fiat monetary system is neither perfect nor definitive, but rather an economic engineering tool. To understand its functioning honestly and objectively, it is necessary to analyze both the capabilities it grants States and the structural risks it introduces into the global economy.

Advantages |
Limitations |
| Crisis flexibility: Allows central banks to react quickly by injecting liquidity or adjusting interest rates to stabilize the economy during a recession. | Dependence on trust: Money has no intrinsic value; it works only as long as society trusts the political and fiscal stability of the issuing government. |
| Facilitation of trade: Functions as an agile and globally accepted medium of exchange, eliminating the costs of storing and transporting physical goods like gold. | Vulnerability to inflation: The ability to create money out of nothing generates the risk of issuing excessively, which dilutes the citizen’s purchasing power. |
| Financial dynamism: Facilitates the expansion of credit to finance infrastructure, businesses, and public services according to market needs. | Debt accumulation: Access to unlimited financing encourages chronic deficits in States, which in extreme cases can lead to financial collapse. |
What alternatives exist to fiat money?
Historically, faced with the loss of value of fiat money due to uncontrolled issuance, citizens have always sought refuge in scarce assets. Traditional goods such as gold and real estate have been the historical vehicles for protecting long-term wealth, since they cannot be multiplied out of nothing.
In the current era, cryptocurrencies have emerged as the digital alternative to this problem, offering a system based on decentralization, limited supply, and total resistance to arbitrary issuance.
Unlike stablecoins, which are unlimited, Bitcoin has a strict limit of 21 million units in its history, which completely eliminates the risk of inflation due to political printing. By being built on blockchain networks, this ecosystem operates without the control of governments or intermediary banks, returning to the user security, divisibility, and full self-custody of their money.
Today, this new paradigm is not limited only to Bitcoin; there is a whole ecosystem of digital assets that includes everything from investment cryptocurrencies to stablecoins linked to the value of the dollar or the euro, allowing any citizen to protect their purchasing power with total freedom and simplicity.
The future of these two forms of money remains open. While cryptocurrencies still have a long way to go and regulatory and technological challenges to face, the history of fiat money demonstrates the structural weaknesses of the fiduciary model. This reality is, precisely, the great reason why more and more people decide not to stand idly by and explore the adoption of digital assets to protect, at least, a percentage of their wealth.
