Finance
The word for interest in ancient Sumerian was mas, which translates directly to calf, a metaphor for the way money could multiply like livestock. This linguistic connection reveals that the concept of finance is as old as the Bronze Age, emerging around 3000 BCE when temples and palaces in West Asia began serving as secure vaults for grain, cattle, and precious materials. The earliest evidence of financial systems dates back to this era, where the Sumerian city of Uruk in Mesopotomia facilitated trade through lending and the charging of interest. By 1200 BCE, cowrie shells were already circulating as money in China, and the Babylonians had established a practice of charging interest at a rate of 20 percent per year. The Code of Hammurabi, written between 1792 and 1750 BCE, codified these banking operations into law, proving that the management of money was a central pillar of civilization from its very inception. Even in ancient Greece and Egypt, the terminology for interest, tokos and ms respectively, meant to give birth, reinforcing the idea that money was expected to grow and reproduce value for the lender.
The Birth of Exchange
The transition from barter and livestock to coinage began in the years between 700 and 500 BCE, marking a pivotal shift in how value was stored and transferred. Herodotus records the use of crude coins in Lydia around 687 BCE, and by 640 BCE, the Lydians had opened permanent retail shops to utilize this new currency. Shortly after, cities in Classical Greece, including Aegina, Athens, and Corinth, began minting their own coins between 595 and 570 BCE. The Roman Republic attempted to regulate these practices, outlawing interest through the Lex Genucia reforms in 342 BCE, though the law was largely unenforced. Under Julius Caesar, a ceiling on interest rates was set at 12 percent, and later under Emperor Justinian, it was lowered to between 4 and 8 percent. The first stock exchange was opened in Antwerp in 1531, followed by the London Stock Exchange in 1773 and the New York Stock Exchange in 1793. These institutions created the infrastructure for the modern financial system, allowing assets to be bought, sold, and traded as financial instruments such as currencies, loans, bonds, shares, stocks, options, futures, and swaps.
The Academic Separation
For centuries, the study of money was intertwined with economics and accounting, but the middle of the 20th century marked a distinct turning point when finance emerged as a separate academic discipline. The earliest doctoral programs in finance were established in the 1960s and 1970s, creating a formalized field of study focused on the planning, organizing, leading, and controlling of an organization's resources to achieve its goals. This separation allowed for the development of specialized subfields such as mathematical finance, financial law, financial economics, and financial engineering. The discipline began to rely on the scientific method to test theories, a practice now covered by experimental finance. Today, finance is widely studied through career-focused undergraduate and master's level programs, with the earliest doctoral programs serving as the foundation for modern financial theory. The field now encompasses a broad range of activities, from asset and money management to risk and investment management, all aimed at maximizing value and minimizing volatility.

What year did Louis Bachelier defend his doctoral thesis on quantitative finance?
Louis Bachelier defended his doctoral thesis in 1900, which is considered the first scholarly work in the field of quantitative finance. This work laid the groundwork for the modeling of derivatives, interest rate risk, and credit risk using tools such as Itô's stochastic calculus.
How much assets under management did sustainable finance reach globally in 2022?
Sustainable finance reached US$30.3 trillion in assets under management globally as of 2022. This growing segment of global capital markets represents the integration of environmental, social, and governance considerations into investment analysis and portfolio management.
What year did the Wall Street crash occur?
The Wall Street crash occurred in 1929. This event, along with the 2008 financial crisis, serves as a stark reminder of the volatility that can arise when market variables move unpredictably.
The application of sophisticated mathematics to finance began with Louis Bachelier's doctoral thesis, defended in 1900, which is considered the first scholarly work in the field. This work laid the groundwork for what is now known as quantitative finance, or mathematical finance, which includes the modeling of derivatives, interest rate risk, and credit risk. The field relies on tools such as Itô's stochastic calculus, simulation, and partial differential equations to price and hedge a wide range of asset-backed, government, and corporate securities. In the modern era, quantitative finance has become synonymous with financial engineering, underpinning a bank's customer-driven derivatives business and designing bespoke over-the-counter contracts. Quants, or quantitative analysts, are the major employers of these sophisticated mathematical models, building and deploying investment strategies that use computer-based techniques and increasingly, machine learning. The field has also given rise to quantum finance, an interdisciplinary area applying quantum mechanical approaches to financial theory to solve problems that have no known analytical solution on classical computers.
The Psychology of Markets
While traditional finance assumes that investors are rational actors who apply risk and return to the problem of investment under uncertainty, behavioral finance challenges this view by studying how the psychology of investors or managers affects financial decisions. This field has grown over the last few decades to become an integral aspect of finance, bridging the gap between what actually happens in financial markets and analysis based on financial theory. Behavioral finance includes empirical studies that demonstrate significant deviations from classical theories, models of how psychology impacts trading and prices, and forecasting based on these methods. A strand of behavioral finance has been dubbed quantitative behavioral finance, which uses mathematical and statistical methodology to understand behavioral biases in conjunction with valuation. The discipline now extends to social finance, which studies the structure of social interactions, how financial ideas spread, and how social processes affect financial decisions and outcomes. This shift acknowledges that feelings and social dynamics play a critical role in the formation of asset prices and market volatility.
The Three Pillars
The financial system is broadly divided into three areas: personal finance, corporate finance, and public finance, each with its own distinct objectives and challenges. Personal finance refers to the practice of budgeting to ensure enough funds are available to meet basic needs while maintaining a reasonable level of risk, involving activities such as paying for education, financing durable goods, buying insurance, and saving for retirement. Corporate finance deals with the actions that managers take to increase the value of the firm to the shareholders, focusing on capital budgeting, dividend policy, and capital structure. Public finance refers to the management of finances related to sovereign states, sub-national entities, and associated public agencies, encompassing the identification of required expenditures, the source of revenue, and the budgeting process. Central banks, such as the Federal Reserve System in the United States, the European Central Bank, and the Bank of England, act as lenders of last resort and influence monetary and credit conditions in the economy. These three pillars overlap and employ various activities and sub-disciplines, chief among them investments, risk management, and quantitative finance.
The Modern Crisis
The financial system is not immune to the risks inherent in any financial action, and history has shown that these risks can lead to catastrophic failures. The Wall Street crash of 1929 and the 2008 financial crisis serve as stark reminders of the volatility that can arise when market variables move unpredictably. In the 2008 crisis, customers queued outside a Northern Rock branch in the United Kingdom to withdraw their savings, highlighting the fragility of the banking system. Financial risk management is the practice of protecting corporate value against financial risks, often by hedging exposure to these using financial instruments. The focus is particularly on credit and market risk, and in banks, through regulatory capital, includes operational risk. For banks and other wholesale institutions, risk management focuses on managing and hedging the various positions held by the institution, calculating and monitoring the resultant economic capital and regulatory capital under Basel III. The crisis also spurred the development of environmental, social, and governance considerations, which have become integral to investment analysis and portfolio management, with sustainable finance representing a growing segment of global capital markets, reaching US$30.3 trillion in assets under management globally as of 2022.
The Future of Money
Since the 2010s, financial technology has significantly transformed traditional financial services delivery, creating alternative channels for financial transactions that reduce reliance on conventional banking infrastructure. Mobile payment systems, digital wallets, and peer-to-peer lending platforms have emerged as powerful tools in both developed and emerging markets. The field of computational finance deals with problems of practical interest in finance, emphasizing the numerical methods applied here to solve complex pricing and hedging problems. As markets change rapidly, the finance community is always looking for ways to overcome performance issues that arise when pricing options, leading to research that applies alternative computing techniques to finance. The future of finance lies in the integration of these technologies with traditional theories, creating a more efficient and resilient system. The discipline continues to evolve, with new subfields such as experimental finance and quantum finance pushing the boundaries of what is possible. The financial system remains a dynamic force, channeling money from savers and investors to entities that need it, ensuring that the process of earning interest or dividends continues to drive economic growth.
