The history of finance is older than writing, older than money, older than the state. And yet most of us go through life without ever being told its story.
Look closer, and you find something extraordinary: the entire edifice of human civilisation — trade, writing, mathematics, money itself — was built on financial foundations.
I came to this not as a banker, but sideways — as a saver and investor learning by doing, and through years of working as a financial specialist with SMEs, Banks and MFIs, and development projects across Africa, the Middle East, and Asia, where the gap between financial systems and the people they were meant to serve was something you felt every day.
Along the way, I recognised something simple: money has rules. Markets have rules. Not understanding them puts you at a permanent disadvantage.
In this article, I share some highlights of the history of money and finance as I discovered it. It is not a story of capitalism, but a story of human cooperation.
Clay tablets and spice ships, coins stamped in Lydia and paper notes printed in Song Dynasty China, wandering mathematicians and merchant families who rewrote the world.
The oldest story we have is a financial one — and it belongs to all of us.
Before Capitalism, There Was Credit
Let us start with a provocation. When most people hear the word ‘finance’, they think capitalism. Markets. Wall Street. The accumulation of wealth by the few at the expense of the many. It is an association with a long history and, in many cases, legitimate grievances. But it is also profoundly incomplete — because it mistakes a recent chapter for the whole book.
Finance is not a product of capitalism. Finance is far older. And its oldest roots have nothing to do with profit.
The anthropologist David Graeber, in his landmark book Debt: The First 5,000 Years, makes a case that should unsettle our assumptions: credit and debt — the fundamental architecture of finance — predate money itself. Before coins. Before markets. Before states. Human beings were already keeping track of what they owed each other.
Think about what that means. In early agrarian communities, a neighbour who helped you bring in the harvest was owed something in return — a future favour, a portion of food, a contribution of labour at planting time. A gift at a wedding created an obligation. A bad harvest meant a debt to the family that shared its grain. None of this required currency. It required only memory, trust, and a shared sense of what was fair.
This is where finance begins. Not on a trading floor. Not in a bank vault. In the oldest human relationships — between families, between communities, between individuals who depended on each other to survive. The logic of debt and credit, of obligation and reciprocity, is woven into the fabric of social life itself. It is, in the deepest sense, a technology of solidarity.
“Money is not the thing itself. It is the memory of the obligation.”
— David Graeber, Debt: The First 5,000 Years
The clay tablets of ancient Sumer did not invent something new when they recorded debts and credits. They were formalising something ancient — giving institutional form to relationships that communities had been managing informally for thousands of years. Writing was the innovation. The underlying logic of ‘I owe you, you owe me’ is as old as human cooperation itself.
This matters because it changes how we read the history of finance. It is not the story of how capitalism colonised human life. It is the story of how one of humanity’s most fundamental social practices — the tracking of mutual obligation — evolved, scaled, and became increasingly sophisticated over millennia. Sometimes serving human flourishing. Sometimes, yes, captured by power and turned against it. But the tool itself is not the problem.
Finance, understood this way, is one of the oldest expressions of what makes us human: the capacity to cooperate across time, to make promises, to honour obligations, to build something together that none of us could build alone. That is the finance worth reclaiming.
The First Thing Humans Ever Wrote Was a Receipt
Here is a fact worth sitting with: the oldest writing in the world is not a poem, not a prayer, not a declaration of war. It is an accounting record.
Around 3200 BCE, in the city-state of Uruk in what is now southern Iraq, Sumerian scribes began pressing reed styluses into wet clay tablets to record the movement of goods — grain entering a temple storehouse, barley disbursed as wages, livestock transferred between hands. The earliest tablets are, in essence, invoices and ledgers. Writing was not invented to capture beauty or to preserve history. It was invented because commerce had grown too complex to manage from memory.
The cuneiform script that emerged from this practical need is considered the earliest writing system on earth. And the need that gave birth to it was a financial one: tracking debts, credits, and transactions in a society that had outgrown the capacity of human recall.
The Sumerians did not stop at notation. Their clay tablets record wages differentiated by trade — codified in the Code of Hammurabi around 1750 BCE. They recorded loan agreements with named witnesses and authenticated them with cylinder seals — the world’s first signatures. Temples functioned as proto-banks: storing wealth, extending credit, managing the economic life of entire city-states. What looks, from the outside, like ancient religion was, on closer inspection, also ancient finance. The first institution ever to hold deposits, manage accounts, and extend loans was a place of worship.
“The first abstract communication system consisted of counters for counting and accounting.”
— Denise Schmandt-Besserat, archaeologist
The relationship between mathematics and commerce was forged here, too. And this is no coincidence — as explored in my article on why poor math skills are the hidden enemy of financial education, numeracy and financial capability have always been intertwined, and we need to master the basics of math to be financially literate.
Clay tablets from Babylon, dating to around 1700 BCE, contain sophisticated algebra, quadratic equations, and the Pythagorean theorem — calculated centuries before Pythagoras was born. These were not theoretical exercises. They were tools for trade: computing interest, measuring land, calibrating yields. Mathematics, as we inherited it, was largely built to serve financial problems.
Money: The Technology That Changed Everything
Before we can tell the story of medieval banks and stock exchanges, we need to tell the story of money itself. Because money — in its many forms across history — is the great enabling technology of finance. Every financial innovation built on top of it was only possible because of what money is: a medium of exchange, a unit of account, and a store of value.
The earliest form of money was not money at all. It was barter — the direct exchange of goods. Barter breaks down the moment an economy grows, because it requires what economists call the double coincidence of wants: you must find someone who has what you need and needs what you have, at the same moment. That is a very fragile system.
So people began using commodity money: objects with intrinsic value that could serve as a common medium. Cowrie shells circulated across Africa, Asia, and the Pacific for thousands of years. Grain and livestock were used in early Mesopotamia — the same grain tracked on those cuneiform tablets. Salt was so prized in ancient Rome that soldiers were sometimes paid in it; the word ‘salary’ derives from the Latin salarium, the salt ration. Wealth, in the ancient world, was often literally edible.
But commodities are heavy, perishable, and hard to divide. The leap to metal changed everything.
Around 600 BCE in Lydia (modern Turkey), King Alyattes minted what became the most influential early coinage: the Lydian stater, stamped from electrum, a naturally occurring alloy of gold and silver. Each coin bore a stamped image functioning as a denomination — a government guarantee of weight and value. Lydia grew so wealthy that its last king, Croesus, entered legend. When we say someone is ‘as rich as Croesus,’ we are invoking a monetary revolution from 600 BCE.
Note: Chinese archaeologists have found evidence of an earlier coin mint at Guanzhuang in Henan Province, dating to around 640 BCE. This is a recent and contested scholarly claim; while it may push the earliest-known coinage back slightly, the Lydian stater remains the most studied and most influential model in the ancient monetary world. The archaeology is live, and the precise question of ‘first coin’ remains open.
Coins solved the problems of commodity money: durable, portable, divisible, and fungible. Greece, Persia, and Rome expanded on the Lydian model, turning coinage into both economic infrastructure and political communication. Roman emperors understood that coins were the most widely distributed medium in the empire — every coin a tiny propaganda poster, pressed into silver and circulated to every corner of the known world.
But coins are heavy. And as trade routes lengthened, moving wealth across continents in metal became impractical and dangerous. The next revolution came from the east.
Paper money was invented in China during the Tang Dynasty (7th century CE) and scaled dramatically during the Song Dynasty (960–1279 CE). Chinese merchants began depositing coins with trusted merchants in exchange for receipts — the world’s first banknotes: a piece of paper representing a claim on something of real value held elsewhere.
Marco Polo, travelling to China around 1271, was astonished by what he found. His chapter on the Yuan emperor’s paper currency — backed by imperial authority alone, with no gold or silver behind it — reads as a traveller’s bewilderment at a system Europeans could barely comprehend. But they were watching the birth of fiat money: currency whose worth derives not from intrinsic material value, but from the trust placed in its issuer.
(Polo, The Travels of Marco Polo, c. 1300)
Europe came to paper money via a different path. In the medieval Italian city-states, merchants carrying gold coins between cities faced a practical problem: bandits. The solution was elegant: deposit your coins with a banker before departure, receive a written note, and redeem it with an affiliated banker at your destination. No gold crossed the roads. The bill of exchange was born — a transferable claim on value, independent of the physical medium that gave it worth.
European banknotes proper followed in the 17th century: the Bank of Sweden issued the continent’s first official paper notes in 1661; the Bank of England followed in 1694. The gold standard, adopted by England in 1816, was an attempt to anchor this paper money to something tangible. It held the system together through the 19th century, before the strains of two world wars and the Great Depression made its rigidity untenable. In 1971, Richard Nixon closed the gold window: the US dollar was no longer convertible to gold. The entire global monetary system became fiat.

The Man Who Changed Numbers — and With Them, Everything Else
Fast forward to 1202. A young Italian mathematician from Pisa, who had grown up accompanying his father on merchant voyages along the North African coast, sits down to write a book. His name is Leonardo of Pisa. History would come to know him as Fibonacci.
The book is the Liber Abaci — the Book of Calculation. Its subject is numbers. Specifically, a set of numbers that almost no one in Europe was using at the time: the Hindu-Arabic numeral system, with ten symbols, a zero, and positional notation. (For a first-hand account of what this numerical revolution means for an investor encountering a foreign number system today, see Indian Numerical System | What a Surprise for an Investor),
Europe in 1202 was doing its arithmetic in Roman numerals. Try multiplying XLVII by CXXIII. You cannot, not easily — not in your head, not on paper. The Roman system was adequate for recording results. It was useless for calculation. Anyone who needed to calculate — a merchant converting currencies, a banker computing compound interest, a trader working out profit margins across three different weights-and-measures systems — had to use a physical abacus and hope for the best.
Leonardo Pisano (known as Fibonacci) had spent years travelling the Mediterranean, learning from Arab and Indian mathematicians. He saw clearly that a different system was not just mathematically elegant — it was commercially revolutionary. Hindu-Arabic numerals made calculation fast, reliable, and accessible to anyone who could learn them.
What Leonardo Pisano did was every bit as revolutionary as the personal computer pioneers who, in the 1980s, took computing from a small group of ‘computer types’ and made computers available to, and usable by, anyone.
The impact was profound. Arithmetic schools proliferated across Italy. Hundreds of hand-copied abbacus manuscripts spread over three centuries. Professor William Goetzmann of the Yale School of Management credits Fibonacci with developing an early form of present-value analysis.
One footnote worth noting: the Fibonacci sequence that now bears his name appears in the Liber Abaci as a small problem about rabbit populations. It was an illustration in a very large book about commerce. The sequence had been known in India for centuries. Fibonacci’s real contribution was not the sequence. It was giving Europe the numerical tools it needed to build the modern financial world.
The Italian City-States and the Architecture of Modern Finance
The Liber Abaci was published in a world already beginning to hum with commercial energy. The Italian city-states of Florence, Venice, and Genoa were emerging as the financial arteries of medieval Europe. What they built in the 13th and 14th centuries was the prototype of modern finance.
Consider the bill of exchange — a document allowing a merchant in Florence to transfer value to a partner in London without physically moving gold across a dangerous and bandit-infested continent. Medieval trade fairs, particularly those in Champagne, became the clearing houses where these instruments were settled. The bill of exchange was a technology: it allowed scale, reduced risk, and created credit across distances. Modern wire transfers are its descendants.
Consider double-entry bookkeeping, formalised by Luca Pacioli in 1494 — but practiced by Italian merchants for at least a century before that. Every debit is matched by a credit. Every transaction creates two entries. A system so elegant and so robust that it remains the foundation of accounting today.
But perhaps the most revealing innovation of the Italian city-states — and one that links directly to finance as it was practised across much of the medieval world — is the commenda contract.
Here is how it worked. A sedentary investor — the stans — provided capital: cash, goods, and a ship. A travelling merchant — the tractator — took that capital, conducted a commercial voyage, and returned with the proceeds. No fixed interest was charged. If the venture succeeded, profits were divided: typically three-quarters to the investor, one-quarter to the merchant (in the unilateral form); or split equally when the merchant contributed capital of their own (bilateral form). If the ship sank, or the goods were lost, the investor bore the loss. The travelling merchant lost their labour, but not their life savings.
The earliest documented commenda dates to 1156 in Genoa, between Ingo da Volta and Ansaldo Baialardo. But the contract was already in common use before that. By the 13th century, it had become, in the words of economic historian Sabatino Lopez, “a medieval innovation of the highest importance” that “contributed greatly to the fast growth of maritime trade.”
The commenda did something structurally remarkable: it separated ownership of capital from the conduct of business, while aligning the interests of both parties around the outcome of the venture. Neither party earned from the mere passage of time. Both had skin in the game. The investor could lose their capital. The merchant could lose their livelihood. Risk was shared, not transferred.
I worked in Islamic finance for a period of my career, and what struck me, encountering mudaraba contracts in practice, was the familiarity of the logic. The mudaraba — the foundational profit-sharing instrument of Islamic banking, prohibited from charging interest on religious grounds — operates on precisely the same principle: a capital provider and an entrepreneur enter a venture together, sharing profits at an agreed ratio, with the capital provider bearing financial loss and the entrepreneur bearing the loss of their effort. No fixed return. No interest. Shared risk.
This is not a coincidence. Scholars now broadly accept that the commenda and the mudaraba share deep historical roots. The mudaraba was practiced by Arab merchants long before the advent of Islam and was transmitted westward through Mediterranean trade routes, Sicily under Muslim and Norman rule, and the commercial exchanges of the Crusades. Venetian merchants, encountering these Islamic partnership contracts, adapted them into the commenda with additional legal controls. The two instruments — Christian Italian and Islamic — are, in a very real sense, evolutionary cousins.
What this tells us is that risk-sharing finance is not a niche religious accommodation. It is one of the most ancient and cross-cultural models of investment that exists. Long before there were banks offering loans at interest, there were arrangements that looked much more like what we would now call venture capital: capital committed to a specific venture, returns conditional on success, losses shared between the parties.
The commenda has since been described as the structural ancestor of modern limited partnerships and private equity. A private equity fund in 2021 used a Spanish legal mechanism — the cuentas en participación — that descends directly from the medieval commenda. The logic that funded a Genoese spice voyage in 1156 funded a major football league transaction 865 years later.
The families who drove the broader Italian financial revolution — the Bardi, the Peruzzi, the Acciaiuoli, and later the Medici — were not merely bankers. They were innovators running what we might recognise today as multinational corporations. At its peak, the Peruzzi firm had over a hundred employees across fifteen branches, from London to Tunis. They financed popes and kings.
They also, of course, failed spectacularly. When King Edward III of England defaulted on his war debts in 1345, the Bardi and Peruzzi banks — overextended, undiversified, politically entangled — collapsed. A financial crisis rippled across Europe. Some economic historians trace a direct line from this collapse to the great depression of the 1340s, which left medieval Europe weakened on the eve of the Black Death.
The Medici, arriving later, had learned the lesson. Their genius was structural: a holding company owning partially independent branches, liability ring-fenced between them. The Medici invented the modern corporate structure. Finance, at its best, is memory made institutional — it takes the knowledge of what went wrong and builds it into architecture.
When the World Became a Company
Three centuries after the Medici refined the corporate structure, the Dutch took the next logical step: they opened it to everyone.
In 1602, the Dutch East India Company — the VOC — did something that had never been done before. It issued public shares. Any resident of the Dutch Republic could subscribe, with no minimum investment and no maximum. Its charter stated simply: ‘All the residents of these lands may buy shares in this Company.’
The shares were tradable. A secondary market emerged almost immediately — first on a wooden bridge over the Damrak harbour, then in a chapel, then in a purpose-built exchange hall. The Amsterdam Stock Exchange was born, more or less on a bridge.
The VOC also introduced limited liability: shareholders could lose what they invested, but not more. This seemingly simple legal principle transformed the calculus of investment. It made it rational for ordinary citizens — not just the wealthy — to commit capital to risky ventures. It democratised risk.
“Four centuries ago, the stock exchange in Amsterdam laid the foundation for democratizing investment, enabling individuals beyond the affluent elite to participate in economic growth.”
— Larry Fink, BlackRock CEO, 2025 Annual Letter to Investors
Within years of the VOC’s IPO, Amsterdam’s share traders had invented forwards, options, and what we now call derivatives. By 1680, the financial instruments available on the Amsterdam exchange were, by scholarly assessment, as sophisticated as anything available today — as Lodewijk Petram documents in The World’s First Stock Exchange.
The dynamics Joseph de la Vega described in his 1688 Confusion of Confusions — speculative bubbles, herd behaviour, insider manipulation — would not look unfamiliar to anyone who has watched how markets really work. Four hundred years on. The instruments are more complex. The speeds are incomprehensible. The scale is global. The underlying logic — pooling capital, distributing risk, pricing uncertainty — is unchanged.
Why This History Matters
Finance has a reputation problem. It is associated with excess, abstraction, and crisis. The 2008 financial collapse, the recurring cycle of boom and bust — these are real, and their costs are real. But they are not the whole story.
The beginning of the story is a Sumerian scribe pressing a reed into clay.
It is early humans solving the double-coincidence-of-wants problem with cowrie shells and then metal coins.
It is Song Dynasty merchants replacing heavy bronze with paper, and Italian merchants replacing dangerous road travel with a piece of paper redeemable across a continent.
It is a medieval mathematician writing a book so merchants could calculate without an abacus. It is a Dutch company opening ownership of global trade to anyone with a few guilders to spare.
It is Genoese merchants and Arab traders converging on the same risk-sharing logic, centuries apart, because it solved the same fundamental problem: how do you fund a risky venture when neither party can afford to lose everything?
At every step, financial innovation solved a real problem.
Barter was cumbersome — commodity money solved it. Commodity money was heavy — coins solved it.
Coins were dangerous to move — paper and credit instruments solved it. Credit was hard to scale across borders — banking networks solved it.
Capital for risky ventures was concentrated among the wealthy; joint-stock companies and public markets solved it.
Fixed-interest lending was religiously or practically problematic — risk-sharing contracts solved it.
Finance, at its core, is a technology for organising human cooperation across time and space. It allows strangers to trust each other. It allows risk to be pooled and distributed. It allows the future to be discounted into the present and the present to be invested in the future.
The history of money and finance is not a footnote to human history. It is, in large part, the engine of it. Understanding that history is not an academic exercise. It is context. It tells you why your bank account exists, why your mortgage has an interest rate, why there is a market where you can own a fraction of a company whose ships once crossed the Pacific.
These are not abstract systems handed down from on high. They are human inventions, built to solve human problems, refined over millennia. And understanding them is the first step toward financial freedom.
A Common Language for a Common World
There is one more thing worth saying — and it tends to get lost in the noise of financial crises and market scandals.
Finance and accounting today are among the most genuinely universal languages humanity has ever produced. The International Financial Reporting Standards, applied in over 140 countries. The Basel Accords on banking regulation set capital requirements across borders. The conventions of double-entry bookkeeping, unchanged in their logic since Luca Pacioli codified them in 1494, are legible to an accountant in Lagos as much as one in Oslo or São Paulo.
This is not a small thing. Language divides us. Law divides us. Culture, religion, and politics divide us. But a balance sheet drawn up in Milan is intelligible to a banker in Shanghai. A bond prospectus issued in New York can be read and evaluated by an investor in Nairobi. The rules of the game — imperfect, contested, constantly evolving — are nonetheless shared.
Consider Islamic finance, which prohibits riba — interest — on religious grounds. As we saw in the story of the medieval commenda, this is not a modern invention; the logic of risk-sharing finance runs deeper in financial history than the logic of fixed-interest lending. And today, Islamic finance integrates. Sukuk bonds, murabaha contracts, profit-sharing structures: these instruments comply with Sharia law while being structured to be comparable, evaluable, and investable alongside conventional financial products. An investor in London can hold an Islamic bond issued in Malaysia. The differences are real and worth respecting. But the common framework makes them legible to each other. For a practical overview, see the IMF’s primer on Islamic finance.
This kind of integration does not happen by accident. It is the product of centuries of gradual standardisation — from the Champagne trade fairs of the 12th century, where merchants from across Europe settled accounts in a shared system, to the Bretton Woods conference of 1944, where 44 nations sat down to design the post-war monetary order, to the Basel Committee of today, where central bankers quietly agree on the rules that govern the capital sitting in your savings account.
“Gold is money. Anything else is credit.” J.P. Morgan
Morgan’s remark carries a sceptic’s edge. But even credit — the most abstract form of financial value — only works because of trust in a shared system. And that shared system is, in its way, one of the great cooperative achievements of human civilisation.
Our markets are more and more interconnected. A crash in one corner of the world ripples into savings accounts on the other side of the planet within hours. That interdependence demands more care, more vigilance, more international coordination — not less. But it also invites us to recognise something we too easily forget: how many bridges we have already built. How much cooperation already exists, quietly, in the plumbing of the global financial system.
The Sumerian scribe recording a grain transaction in Uruk was not so different from the accountant in your local bank keying data into a ledger today. Both are doing the same thing: creating a record that allows strangers to trust each other, across time and space. That is a remarkable thing. And it deserves, at least once, to be acknowledged.
Why I Started Paying Attention
I should be honest about where this comes from. I did not start out fascinated by financial history. I started out curious — and a little unsettled — by how much money shapes everyday life, and how rarely the underlying logic gets explained.
Part of it came from my own experience as a saver and investor, learning by doing, making mistakes, gradually building a clearer picture of how markets, returns, and risk actually work. Part of it came from work — a career in development finance, alongside microfinance institutions, cooperatives, savings groups, farmers, SMEs, and entrepreneurs across Africa, the Middle East, and Asia. In that world, you see close up how transformative it is when someone gains access to financial tools they understand — and equally, how much friction accumulates when the gap between a financial system and the people it is meant to serve remains wide.
Some of that work took me into Islamic finance. Working with institutions and entrepreneurs who structured deals not as loans, but as partnerships — where the financier and the entrepreneur entered a venture together, shared the upside, and shared the risk of failure — I found myself thinking: this is not exotic. This is ancient. This is, in fact, the model that funded the Venetian maritime empire before anyone had heard of a stock exchange.
The more I learned — about how money actually works, about the underlying mathematics of investment, about how markets function and how the economy is structured — the more the fog lifted. Not because finance is complicated. Because the basics, once laid out plainly, are genuinely illuminating. There are rules to this game. And once you know them, you see the board differently.
That is what Sweat Your Assets is. An attempt to share what I have learned along the way — clearly, honestly, without pretending it is more mysterious than it is. The history in this post is part of that. Understanding where these systems came from — that money was a solution to a problem, that credit predates coins, that risk-sharing finance is older than interest-based lending, that the stock market was invented on a bridge in Amsterdam — makes the present less opaque. It puts you on firmer ground.
And then there is compounding. Albert Einstein — whether or not he actually said it — is credited with calling compound interest the eighth wonder of the world. The attribution may be apocryphal, but the observation is not.
Compounding is the most extraordinary force in personal finance: the mechanism by which returns generate further returns, quietly, relentlessly, across time. It rewards patience and punishes delay. The snowball effect of compounding deserves your full attention.
This is, in the end, what the whole arc of financial history points toward.
From Sumerian grain records to Lydian coins, from Fibonacci’s calculations to Medici credit networks, from the commenda partnerships of medieval Genoa to Amsterdam’s first stock exchange to the globally interconnected markets of today — all of it has been building toward a world where an ordinary person, armed with knowledge and discipline, can put the extraordinary force of compounding to work in their own life.
That is the promise of financial literacy. And it is why the history of finance is not just an academic curiosity. It is the backstory of your financial freedom.
