Origins, history, and evolution of the most important tool of social cooperation: money.
In the early forms of societies, before the advent of currency, economic transactions were managed quite differently compared to today. The gift economy was often the dominant practice: goods were exchanged freely without a direct economic return, but often based on the social recognition of various individuals within the communities.
As societies evolved, the gift economy began to show its limitations, especially due to its inefficacy in broader contexts or among groups without pre-existing ties. Gradually, people adopted the barter system, where goods and services were exchanged directly.
Origins of money
Despite being an evolution from the gift economy, the barter system still had significant limitations. The most critical issue was the need for a “double coincidence of wants“: for an exchange to occur, two parties had to mutually desire what the other offered. This created inefficiencies and restricted the scale and speed of exchanges. To overcome these challenges, the invention of money emerged—a commonly accepted medium of exchange that could be divided and accumulated. The early forms of money varied based on the culture and region of the society.
The first true form of money was “commodity money,” representing specific goods such as livestock, grain, or salt used as a medium of exchange. This allowed greater flexibility in transactions, enabling indirect exchanges as well.
The goods used in exchanges were items that needed to possess specific characteristics:
- Longevity to avoid value loss.
- Widespread availability to ensure broad acceptance.
- Easy verifiability of their qualities to reduce uncertainties during payment.
Although goods used for exchange represented a significant advancement over barter, they had evident limitations: portability, divisibility, and susceptibility to value loss due to environmental or seasonal factors.
An important turning point occurred with the introduction of precious metals, such as gold and silver, into commercial exchanges. These metals, due to their characteristics—durability, ease of transport, divisibility, and relative scarcity—were well-suited to serve as a medium of exchange.
The true evolution came with coinage, the transformation of precious metals into metallic money. It established a standardized and equal value for each piece, further facilitating portability and ensuring certainty in the value of the exchanged good.
Eventually, the gold standard became dominant, providing a degree of stability and convenience in trade. Gold emerged as the primary medium of exchange for several reasons intrinsic to its characteristics. Firstly, gold is a rare metal that requires significant effort to extract. Additionally, it boasts exceptional durability, resisting corrosion and oxidation—crucial qualities for a preservable store of value. Gold is also divisible, making it suitable for coinage. All these factors contributed to gold becoming the standard for economic transactions for much of history.
The evolution of money
With the evolution of economic systems, the need for a more manageable medium of exchange than gold became evident.
It was 7th-century China that took the first significant step in this direction with the introduction of paper money, or banknotes. Initially, banknotes were promises of immediate payment, representing a specific quantity of gold deposited in a bank. This allowed transactions to occur without the need to physically transport gold, thereby facilitating trade and the economy. As banking systems became more structured and widespread, banknotes became the dominant form of money in the 18th century, marking a turning point in the evolution of money.
Banks soon realized they could issue a nominal value in banknotes greater than the corresponding amount they could cover with their gold reserves. This practice, known as fractional reserve banking, is the foundation of the modern banking system. Banks relied on the assumption that not all note holders would demand their gold simultaneously.
However, this system posed risks. If, for any reason, trust in the bank weakened, there could be a run on the banks. If demands exceeded the bank’s gold reserves, it could lead to potential bankruptcy.
Hence, the transition to what has gone down in history as the Gold Standard became natural: in this case, fully convertible paper money was used, as the gold value of the issued currency equaled the amount of gold held by the central bank.
The first nation to adopt this monetary system was Britain, followed by Germany.
In 1914, the onset of World War I marked the abandonment of the full convertibility of currency into gold in several countries, except for the United States. From that point, only a fraction of the circulating currency was backed by gold. This reduction in the gold reserve facilitated the expansion of the monetary base, intended to finance significant military expenses.
In 1924 and 1925, convertibility was restored in both Germany and Britain, but due to the 1929 depression, starting in 1931, countries decided to suspend the Gold Standard.
Meanwhile, the United States had become the world’s leading economic power, and in 1944, with the Bretton Woods agreements, the Gold Exchange Standard replaced the Gold Standard, with the U.S. dollar becoming the reference currency.
The Gold Exchange Standard, a system based on fixed exchange rates between all currencies pegged to the U.S. dollar (itself pegged to gold), gained approval from all countries. They supplemented their central banks’ gold reserves with reserves in U.S. dollars.
This monetary system also did not last long. In 1971, U.S. President Richard Nixon ended the convertibility of the dollar into gold, definitively concluding the era of the Gold Exchange Standard. The event became known as the “Nixon Shock” and ushered in the era of fiat currencies, currencies based on the trust people place in the institutions that issue them.
The term ‘fiat’ comes from Latin and can be translated as ‘let it be done‘; essentially, it signifies an order given by the government, ‘done by decree’.
Fiat currencies have no underlying assets, and central banks can adjust their supply to manage the economy, responding to economic crises, wars, inflation, or deflation.
The birth of Bitcoin
In a globally unstable economic environment marked by growing wealth disparities, the advent of Bitcoin represents a potential revolutionary element. Its architecture provides a tangible alternative to issues associated with fiat currency, offering a set of features that could lead to a fairer and more stable economic system.
Unlike fiat currency, whose issuance at the discretion of monetary authorities can theoretically be infinite, the maximum quantity of Bitcoin is capped at a fixed limit of 21 million units. This inherent restriction excludes the danger of inflation fueled by the incessant production of new money, thereby neutralizing the effects of distortions introduced by the Cantillon effect and promoting a more impartial economic system for every participant.
