The Financial System: Casinos, Utilities, and Crises
On a Monday morning in April 1992, a stockbroker named Harshad Mehta stood on the floor of the Bombay Stock Exchange, watching the numbers climb. The BSE Sensex — India's benchmark stock index — had been on a tear for months. Stocks were doubling, tripling, quadrupling in value. Ordinary people who had never owned a share in their lives were borrowing money to buy stocks. Harshad Mehta was their hero. Newspapers called him "the Big Bull." He drove a Lexus — one of the first in India — to the stock exchange.
What almost nobody knew was that Mehta had been systematically looting the Indian banking system to fuel the rally. He had exploited gaps in the way banks settled government bond transactions, siphoning billions of rupees from banks into the stock market. The rising prices were not the result of a booming economy. They were the result of stolen money chasing stocks.
When journalist Sucheta Dalal exposed the scheme in the Times of India, the bubble burst. The Sensex crashed. Banks discovered they were missing billions. Investors who had bought stocks at inflated prices lost their savings. Mehta was arrested. Some of the bankers who had been complicit were found dead in circumstances that were never fully explained.
Now here is the question that has haunted economies since the first stock was traded: is the stock market a casino or an engine of growth? Is the financial system a useful servant of the real economy — or a dangerous master that periodically runs amok?
The answer, as we will see, is yes. It is both. And understanding when it is one versus the other is one of the most important things economics can teach you.
Look Around You
If your family has a savings account, a life insurance policy, a pension plan, or a mutual fund — you are already part of the financial system. If your family has ever taken a loan to buy a house, start a business, or pay for education — you are part of the financial system. Even if you only deal in cash, the interest rate on your savings, the inflation rate that erodes them, and the exchange rate that determines import prices are all set by the financial system.
You are in it whether you know it or not.
What Is the Financial System, Really?
Strip away the jargon, and the financial system does one fundamental thing: it moves money from people who have it to people who need it.
A farmer in Punjab has a good harvest and earns more than he needs this season. A young woman in Hyderabad has a business idea but no capital. In a world without a financial system, these two would never meet. The farmer's surplus would sit idle — under a mattress, perhaps, or in a pot buried in the courtyard — while the entrepreneur's idea would die for lack of funds.
The financial system connects them. The farmer deposits his surplus in a bank. The bank lends it to the entrepreneur. She builds her business, earns a profit, repays the loan with interest. The bank passes some of that interest to the farmer. Everyone is better off.
This is the utility function of finance — channeling savings into investment. It is genuinely valuable. Without it, no factory could be built, no house could be purchased on a loan, no government could fund a highway without having the entire cost in hand.
But this useful function sits alongside a dangerous one — and the two are tangled together in ways that are difficult to separate.
"The job of finance is to provide capital to enterprises and to provide a channel for savings. Everything else is a game." — Paul Volcker, former Chairman of the US Federal Reserve
The Building Blocks: What Financial Markets Actually Do
Let us walk through the main components of the financial system, one by one, and understand what each does — and what can go wrong with each.
Banks: The Foundation
Banks are the oldest and simplest financial institutions. They take deposits from savers and make loans to borrowers. The difference between the interest they charge on loans and the interest they pay on deposits — the "spread" — is their profit.
This seems straightforward, but there is a hidden magic trick at the heart of banking: maturity transformation. Your bank deposit can be withdrawn any time — it is short-term. But the loan the bank makes — a home loan, a business loan — might not be repaid for ten or twenty years. The bank has taken your short-term money and transformed it into long-term investment.
This works beautifully as long as not everyone withdraws at once. If they do, the bank fails — because it cannot call in its long-term loans overnight. This vulnerability is the reason bank runs exist, and the reason governments insure deposits and central banks serve as lenders of last resort.
Stocks (Equity): Owning a Piece of a Business
When a company sells stock, it is selling ownership. If you buy shares of Infosys, you own a tiny fraction of Infosys. If the company does well, your shares become more valuable. If it pays dividends, you get a share of the profits. If it fails, you lose your money.
The stock market serves a real economic purpose: it allows companies to raise capital from thousands of investors, spreading the risk. Instead of one rich person funding a factory, ten thousand ordinary people can each contribute a small amount, sharing both the risk and the reward.
The problem is that stocks also have a price that moves every second, and that price is not always connected to the actual value of the business. When people buy stocks not because they believe in the business but because they think the price will go up — and they plan to sell to someone else at a higher price — that is speculation. And when speculation becomes the dominant force in the market, the stock market stops being an engine of growth and becomes a casino.
Bonds: Lending Money to Governments and Companies
A bond is a loan. When you buy a government bond, you are lending money to the government. It promises to pay you back with interest. Corporate bonds work the same way — you are lending to a company.
Bonds are generally considered safer than stocks because the return is fixed and predictable. But "safer" does not mean "safe." If the borrower defaults — as Argentina has done multiple times, and as many companies do — you lose your money.
The bond market is actually larger than the stock market, though it gets less attention. Government bond markets are particularly important because the interest rate on government bonds — especially US Treasury bonds — serves as the baseline for all other interest rates in the economy.
Derivatives: Bets on Bets
This is where the financial system gets truly abstract. A derivative is a financial contract whose value is "derived" from something else — a stock, a bond, a commodity, an interest rate, even the weather.
The simplest derivative is a futures contract. An Indian wheat farmer might sell a futures contract promising to deliver wheat at a set price in six months. This protects the farmer: no matter what happens to the market price, he knows what he will get. The buyer of the contract — perhaps a flour mill — knows what it will pay. Both sides reduce their uncertainty. This is hedging, and it is genuinely useful.
But derivatives can also be used for pure speculation — placing bets on price movements without any intention of buying or selling the underlying commodity. And when speculators use borrowed money (leverage) to make these bets, the potential for catastrophe multiplies.
The global derivatives market is estimated at over $600 trillion in notional value — more than six times the entire world's GDP. Most of this is benign hedging. But the portion that is speculative, leveraged gambling has been at the center of nearly every major financial crisis in the past three decades.

THE USEFUL FUNCTION: Channeling savings to productive investment
THE DANGEROUS FUNCTION: Speculation, leverage, systemic risk
The Casino Function: When Finance Eats the Economy
There is a term that economists use with increasing alarm: financialization. It refers to the growing size, power, and influence of the financial sector relative to the real economy — the economy of farms, factories, shops, and services.
Consider these numbers:
In 1980, the financial sector accounted for about 4 percent of the US economy (GDP). By 2020, it was close to 8 percent. Financial sector profits, which were about 10 percent of total corporate profits in the 1950s, rose to over 30 percent by the 2000s.
This means that a growing share of the economy's output and profits is going not to people who make things, grow things, or provide services — but to people who move money around.
Is this a problem? Many economists think so. When the financial sector grows faster than the economy it is supposed to serve, something has gone wrong. It is like a circulatory system that grows so large it starts consuming the body's nutrients instead of delivering them.
"Finance is a service industry. It should serve the needs of the real economy, not the other way around." — Adair Turner, former Chairman of the UK Financial Services Authority
The Harshad Mehta Story, Continued
Let us return to our opening story, because it illustrates financialization perfectly.
Harshad Mehta did not build a factory. He did not create a product. He did not employ thousands of workers in productive activity. What he did was exploit weaknesses in the banking system to channel money into the stock market, driving up prices and profiting from the rise.
The money that flowed into stocks during the 1992 boom came largely from banks — which means it came from depositors. Ordinary people's savings were being used, without their knowledge, to inflate a stock market bubble. When the bubble burst, those savings were gone.
The Mehta scam was illegal. But the broader phenomenon — money flowing from productive uses into speculative financial activity — is perfectly legal and happens every day. When a company uses its profits to buy back its own shares (boosting the stock price) rather than invest in new capacity or raise wages, that is financialization. When a real estate developer holds land empty to speculate on price increases rather than building housing, that is financialization. When a bank makes more money from trading derivatives than from lending to businesses, that is financialization.
What Actually Happened
The Harshad Mehta scam of 1992 involved the diversion of approximately Rs 5,000 crore ($1 billion at the time) from the banking system to the stock market. Mehta exploited the manual, paper-based system of settling government bond transactions between banks, creating fictitious transactions to siphon funds. The Sensex rose from about 1,000 in January 1991 to nearly 4,500 in April 1992 — a 350 percent increase fueled largely by this manipulation. When the scam was exposed, the market lost nearly 50 percent of its value. Mehta was charged with 72 criminal offenses. He died in 2001 while still under trial. The scam led to sweeping reforms: the creation of the National Stock Exchange, the introduction of electronic trading, the strengthening of SEBI (the Securities and Exchange Board of India), and the modernization of the payments system. India's financial system became significantly more robust as a result — but at enormous cost to investors who trusted the market during the bubble.
Bubbles Through History: We Never Learn
The Mehta scam was not unique. Financial bubbles are as old as financial markets themselves. They follow a remarkably consistent pattern, and the fact that they keep recurring despite centuries of experience tells us something important about human nature.
Tulip Mania: The Netherlands, 1637
In the 1630s, the Dutch Republic was the richest and most commercially sophisticated country in Europe. Dutch merchants traded across the world, Dutch banks were the most advanced, and Dutch society was prosperous and confident.
Into this prosperity came the tulip.
Tulips had been introduced to Europe from the Ottoman Empire in the sixteenth century. The Dutch, with their deep love of gardening, became obsessed. Rare varieties — those with unusual color patterns caused by a virus in the bulb — commanded increasingly high prices.
By 1636, tulip bulb trading had become a speculative frenzy. Contracts for future delivery of bulbs — early derivatives — were being traded in taverns. Prices doubled, then doubled again. A single bulb of the Semper Augustus variety reportedly sold for 12,000 guilders — enough to buy a grand house on Amsterdam's most prestigious canal.
People who had never grown a tulip were borrowing money to buy tulip futures. Servants and chimney sweeps became tulip speculators.
In February 1637, the market suddenly collapsed. Buyers stopped buying. Prices fell 90 percent in days. Fortunes were wiped out. The Dutch economy, fundamentally sound, recovered relatively quickly. But the tulip mania became history's most famous example of speculative madness.
The South Sea Bubble: England, 1720
The South Sea Company was founded in 1711 with a monopoly on British trade with South America. The problem was that Spain controlled South America and had no intention of letting the British trade there. The company had essentially no real business.
What it had was political connections and a talent for promotion. In 1720, the company proposed to take over the British national debt, offering to convert government bonds into South Sea Company shares. Parliament agreed. The scheme worked as long as the share price kept rising — each new wave of bondholders converting into shares drove the price higher, which attracted more conversions.
The share price rose from 128 pounds in January 1720 to over 1,000 pounds by August. Sir Isaac Newton — the greatest scientific mind of his era — invested early, made a profit, and then invested again at the peak. He lost 20,000 pounds, an enormous fortune. He reportedly said: "I can calculate the motions of heavenly bodies, but not the madness of people."
The bubble burst in September. Thousands were ruined. The Chancellor of the Exchequer was sent to the Tower of London for his role in the fraud.
Lessons That History Keeps Teaching
Every bubble follows the same script:
- A plausible story — new technology, new market, new opportunity — that contains a kernel of truth
- Early profits that seem to confirm the story
- The crowd rushes in, including people who do not understand what they are buying
- Leverage — borrowed money amplifies both gains and losses
- The belief that "this time is different"
- The crash, which is faster and more devastating than the rise
- The search for villains, though the true cause is systemic

Shadow Banking: The Financial System You Cannot See
In 2008, when the global financial system nearly collapsed, many people were bewildered to discover that the crisis did not originate in traditional banks. It originated in a vast, largely unregulated parallel financial system that most people had never heard of: shadow banking.
Shadow banks are financial institutions that perform bank-like functions — lending money, creating credit, taking risks — but are not regulated like banks. They include:
- Hedge funds: Private investment funds for wealthy investors, often using enormous leverage
- Money market funds: Funds that invest in short-term debt, used by companies and individuals as an alternative to bank deposits
- Special purpose vehicles (SPVs): Legal entities created by banks to move assets off their balance sheets, hiding risk from regulators
- Repo markets: Markets where institutions borrow short-term by pledging securities as collateral
The shadow banking system grew for a simple reason: regulation. As governments tightened rules on traditional banks — requiring them to hold more capital, limit risk, and submit to inspections — financial activity migrated to less regulated entities that could do the same things without the constraints.
By 2007, the shadow banking system in the United States was larger than the traditional banking system. It was creating credit, amplifying risk, and linking institutions together in ways that nobody fully understood. When the housing market turned, the shadow banking system amplified the losses and transmitted them across the entire global economy.
India has a smaller but growing shadow banking sector. The crisis at IL&FS (Infrastructure Leasing & Financial Services) in 2018 illustrated the risks: a major non-bank financial company defaulted on its obligations, sending shockwaves through India's financial system. The liquidity crisis that followed affected other non-bank lenders, disrupting credit markets and slowing economic growth.
"If it looks like a duck, swims like a duck, and quacks like a duck, then regulate it like a duck." — Common argument for regulating shadow banks like traditional banks
The Useful Side: What Finance Gets Right
It would be a mistake to see the financial system only as a source of crises and speculation. The useful functions of finance are real and important.
Capital allocation. When Narayana Murthy and six co-founders started Infosys in 1981 with Rs 10,000, they eventually needed far more capital to grow. The ability to sell shares on the stock market — first in India in 1993, then on NASDAQ in 1999 — allowed Infosys to raise the capital it needed to become one of the world's largest IT services companies. Millions of investors shared in that growth. The stock market made this possible.
Risk sharing. When a farmer buys crop insurance, she is using the financial system to spread her risk across thousands of other policyholders and the insurance company's reserves. No individual farmer could absorb the loss of a failed harvest alone. Pooled together, the risk becomes manageable.
Price discovery. When the price of wheat futures rises, it signals that markets expect a shortage. This signal helps farmers decide to plant more wheat and helps importers plan ahead. Financial markets aggregate information from millions of participants and compress it into a price — an imperfect but useful summary of what the world knows and expects.
Access to credit. The single most powerful economic tool for poverty reduction is access to affordable credit. When a woman in a village can borrow Rs 10,000 to buy a sewing machine and start a tailoring business, the financial system — in this case, a microfinance institution or a bank — has done something genuinely valuable.
The challenge is not to destroy the financial system but to keep it in its place — as a servant of the real economy, not its master.
The Financialization of Everything
Here is a trend that should worry us all: the financial system is no longer content to serve the real economy. It is colonizing it.
Housing. In city after city — Mumbai, London, New York, Toronto — housing has become a financial asset first and a place to live second. Investors buy apartments not to live in but to hold as investments, driving up prices beyond what ordinary families can afford. In some Mumbai neighborhoods, a significant fraction of apartments sit empty — held by investors waiting for prices to rise.
Food. Commodity futures markets, originally designed to help farmers hedge their risks, have become playgrounds for financial speculators. When Goldman Sachs and other banks poured billions into commodity index funds in the 2000s, food prices spiked globally. Wheat, rice, and corn prices rose not because of shortages but because financial investors were treating food as an asset class. People in developing countries went hungry so that hedge funds could earn returns.
Education. When student loans become financial products — bundled, securitized, and sold to investors — the incentive shifts from providing good education to providing expensive education. The more students borrow, the more profit the financial system makes. This dynamic has contributed to the student debt crisis in the United States, where total student loan debt exceeds $1.7 trillion.
Healthcare. Private equity firms have been buying hospital chains, dental practices, and nursing homes — not to improve healthcare but to extract financial returns. They cut costs (often including staff and quality), load the companies with debt, extract fees, and move on. The patients and workers are left with degraded services.
"When you start thinking of housing as an asset rather than shelter, of food as a commodity rather than sustenance, of education as a product rather than a right — you have entered a world where finance has captured life itself." — Adapted from various critics of financialization
Think About It
Your family's home serves two functions: it is a place to live and it is a financial asset. When housing prices rise sharply, who benefits and who suffers? What happens when the financial function (investment) dominates the social function (shelter)?
A microfinance loan of Rs 10,000 to a village entrepreneur and a $10 billion derivative bet on oil prices both happen within the "financial system." What distinguishes them? How should we think about what kinds of finance are useful and what kinds are harmful?
If you could design a financial system from scratch, what rules would you put in place to keep it serving the real economy rather than dominating it?
India's Financial System: The Good, the Fragile, the Missing
India's financial system is a work in progress — impressive in some respects, dangerously underdeveloped in others.
The good: India's banking system, though imperfect, reaches deep into the country. The Jan Dhan Yojana program, launched in 2014, opened over 500 million bank accounts for previously unbanked Indians. UPI (Unified Payments Interface) has become the world's most successful real-time payment system, processing billions of transactions. India's stock markets — the BSE and NSE — are well-regulated by global standards, thanks partly to reforms after the Mehta scam.
The fragile: India's banks carry a significant burden of non-performing assets (NPAs) — loans that borrowers have failed to repay. At their peak around 2018, NPAs in the banking system exceeded Rs 10 lakh crore (about $120 billion), mostly concentrated in public sector banks. These bad loans often originated in politically connected lending — banks pressured to lend to favored businesses or sectors regardless of risk. The problem has improved but not disappeared.
The missing: India's corporate bond market is shallow and underdeveloped. In developed economies, companies can raise long-term capital by selling bonds directly to investors. In India, most corporate borrowing still goes through banks, concentrating risk in the banking system. India also lacks a deep market for municipal bonds, which could fund urban infrastructure. And the insurance and pension sectors, while growing, still cover a relatively small fraction of the population.

What Would a Good Financial System Look Like?
If we could design a financial system from scratch, what principles would guide us?
It would serve the real economy. Banks would lend to businesses and individuals for productive purposes. Stock markets would channel capital to companies that create real value. The financial sector would be a means, not an end.
It would be transparent. Everyone would be able to see who owes what to whom, what risks are being taken, and where the vulnerabilities lie. Shadow banking would be brought into the light and regulated.
It would be boring. The best financial system is one you never hear about — like good plumbing, it works quietly in the background. When finance becomes exciting, when traders become celebrities, when financial innovation is celebrated as genius — trouble is usually brewing.
It would spread risk, not concentrate it. Insurance, diversification, and sensible regulation would ensure that no single failure could bring down the system.
It would be fair. Access to credit, savings products, and insurance would be universal, not a privilege of the wealthy. The returns from financial intermediation would be shared more broadly.
We do not have this system. But knowing what it would look like helps us evaluate what we have — and push for something better.
"The financial system should be the servant of industry, not its master." — Adapted from John Maynard Keynes
An Old Story, a New Lesson
There is a parable from the Jataka tales — the Buddhist collection of stories that are among India's oldest narrative traditions. A merchant travels to a distant city with a cartload of goods. Along the way, he must cross a river. The ferryman charges a toll. At first the toll is modest — a few coins for the crossing. But over time, the ferryman grows greedy. He raises the toll, again and again. Eventually, the toll is so high that merchants stop crossing. The ferryman's income drops to zero. The cities on both sides grow poorer because trade has stopped.
The financial system is the ferryman. It provides a valuable service — connecting those who have capital with those who need it, moving money across the river from savers to investors. A reasonable toll — the profits of banks, the fees of fund managers — is fair compensation for this service.
But when the toll grows too large — when the financial sector captures 30 percent of corporate profits, when trading fees and commissions eat into ordinary people's savings, when the complexity of financial products enriches intermediaries at the expense of end users — the ferryman has become a predator. Trade slows. The real economy suffers. And eventually, the ferryman too is impoverished, though he is usually the last to realize it.
The 2008 crisis was the moment the world realized the ferryman had been charging too much. The reforms that followed were an attempt to reduce the toll. Whether they were sufficient — and whether the toll is creeping up again — is the defining financial question of our time.
Think About It
Warren Buffett once said that when the tide goes out, you see who has been swimming naked. What does this mean in the context of financial markets? Think about what rising markets hide and what falling markets reveal. Why do crises always seem to surprise everyone, even though the warning signs were visible in hindsight?
The Bigger Picture
We began with Harshad Mehta and the Bombay Stock Exchange in 1992. We have traveled from tulip-mad Amsterdam to the shadow banks of New York, from the ferryman of the Jataka tales to the UPI revolution in Indian digital payments.
What have we learned?
The financial system is one of humanity's most powerful inventions. It enables the extraordinary alchemy of turning today's savings into tomorrow's growth. Without it, there would be no Infosys, no green revolution, no highways, no home loans. The utility function of finance is real and indispensable.
But the financial system is also one of humanity's most dangerous inventions. When it escapes the bounds of its useful function — when speculation overwhelms investment, when leverage amplifies risk, when the financial sector grows so large that it consumes the economy it was meant to serve — the results are catastrophic. Every major economic crisis in modern history has had a financial dimension.
The challenge — for India, for the world — is to keep the useful function and contain the dangerous one. This requires regulation, transparency, and a political willingness to stand up to the immense power of the financial sector. It also requires citizens who understand the system well enough to demand accountability.
A casino can be fun. A utility keeps the lights on. The financial system must be more utility than casino — more boring than exciting, more servant than master.
That is easier said than done. But understanding the difference is the first step.
"The four most dangerous words in investing are: 'This time is different.'" — Sir John Templeton
They are dangerous because they are always believed. And they are always wrong.
