The journey
Thirteen modules. One story.
Module 1 · What money is
Money is a promise everyone agrees to accept.
A note has almost no value as paper. It works because you trust that the next person will take it.
Module 1 · What money is
It does three jobs.
Medium of exchange
You trade work for money, then money for anything. No barter needed.
Unit of account
One ruler for all prices. A phone, a haircut and a salary in the same unit.
Store of value
Save today, spend later. Inflation slowly erodes this job.
Module 1 · What money is
Barter breaks when wants don't match.
The farmer wants shoes. The shoemaker wants fish. The fisher wants wheat. Nobody can trade directly. A shared token everyone accepts fixes the loop.
Module 1 · What money is
Every rupee you hold is someone else's debt.
A central bank liability. Backed by law and trust in the state.
Your bank's promise to pay you cash on demand. UPI moves these promises.
An asset for the bank. When you took it, it created a deposit somewhere.
Money is a web of IOUs. The rest of this course follows those IOUs.
Module 2 · Origins
5,000 years in ten steps.
Each step moved money further from things and closer to pure promises. Tap any year.
Module 2 · Origins
1971: the last link to gold breaks.
From 1944, currencies were pegged to the dollar and the dollar to gold. On 15 August 1971 the US ended convertibility. Since then, money is backed by law, taxes and trust.

Module 2 · Origins
Today, money is mostly data.

Module 3 · Central banks
The central bank is the bank of banks.
You bank with HDFC or SBI. They bank with the RBI. The government banks with the RBI too. Every rupee transfer finally settles on its books.
Module 3 · Central banks
Six jobs of a central bank.
Issue currency
Sole right to put notes into circulation.
Set the price of money
The policy rate steers every loan and deposit rate.
Settle payments
Banks hold reserve accounts and settle with each other here.
Lender of last resort
Lends to solvent banks in a panic so runs don't spread.
Regulate banks
Sets capital, liquidity and reserve rules.
Manage reserves
Holds dollars, gold and other currencies to defend the rupee.
Module 3 · Central banks
One dial moves the whole economy.
Turn the policy rate. Watch a ₹50 lakh, 20 year home loan respond.
RBI repo rate today: 5.50% (raised 7 Oct 2026). Loan rate assumed at policy rate + 3%.
Module 3 · Central banks
A few committees set the price of money.
6 members: 3 from the RBI including Governor Sanjay Malhotra, 3 external experts. Target: 4% inflation, band 2 to 6%. Meets about every two months.
12 voters: 7 governors plus 5 regional Fed presidents. Chair: Kevin Warsh. Target: 2% inflation. Meets 8 times a year.
Governments set the target. Central banks choose how to hit it. That split is called independence.
Module 4 · How money is created
Two layers of money.
Base money is made by the central bank: cash and bank reserves. Broad money is what people hold: deposits, made mostly by banks lending.
India, January 2026 (RBI). Circle areas to scale.
Module 4 · How money is created
A bank loan creates new money.
The bank does not lend someone's savings. It types two entries: a loan you owe, and a deposit you can spend. Both appear at once.
Source: Bank of England, "Money creation in the modern economy", 2014.
Module 4 · Try it
Make money. Move it. Destroy it.
Module 4 · How money is created
Central banks create money by buying.
To add money, a central bank buys bonds or foreign currency and pays with new reserves. In a crisis it buys in bulk. That's quantitative easing (QE). Selling or letting bonds mature removes money (QT).
Module 4 · How money is created
Printing notes is the small part.
Notes are printed to meet demand for cash, not to create spending power. The real creation happens in bank ledgers.
RBI, January and February 2026. India is cash heavy: about 14% of money is notes. In the UK it is about 3%.
Module 4 · How money is created
Why the money supply keeps growing.
New loans add money. Repayments remove it. In most years lending wins, because economies grow and central banks aim for mild inflation on purpose.

Module 5 · How money moves
A UPI payment, in about two seconds.

banks live on UPI (March 2026), from 21 at launch
Module 5 · How money moves
Banks settle the net, at the central bank.
Millions of payments cancel each other out. At set times, banks pay only the difference, moving reserves between their RBI accounts. Big single transfers use RTGS and settle one by one.
Module 5 · How money moves
Across borders, money hops between banks.
Each hop adds a fee and a delay. That's why cross border transfers can take days, while UPI takes seconds.
Module 5 · How money moves
The world swaps $9.6 trillion of currency a day.
The foreign exchange market is the largest market on Earth. The dollar sits on one side of almost every trade.
BIS Triennial Survey, April 2025. Each trade has two currencies, so shares add to 200%.
Module 5 · How money moves
Central banks still save in dollars.
Countries hold $13.22 trillion of foreign currency reserves. The dollar's share has slipped from about 71% in 1999, while gold buying has surged.
IMF COFER, Q2 2026.
Module 6 · Banks
A bank earns the gap between two rates.
Pays for
Branches, staff, technology, tax.
Absorbs
Loans that go bad. This is the bank's real risk.
Leaves
Profit for shareholders. Plus fee income on cards and services.
Rates are illustrative round numbers.
Module 6 · Banks
Banks borrow short and lend long.
Your deposit can leave today. Their home loan runs 20 years. If too many depositors leave at once, even a healthy bank can fail. That's a run.
withdrawal requests in one day
insured per depositor, per bank (DICGC)
Module 6 · Banks
Three rules hold banks together in India.
of deposits parked with the RBI, earning nothing.
of deposits held in safe assets like government bonds.
minimum owners' capital against risky loans, including buffer (Basel III).
Capital is the shock absorber. It's the owners' money that takes losses before depositors do.
Module 7 · Credit and debt
A loan pulls future income into today.
Interest is the price of that time travel. Lenders charge more when the future looks riskier or when the central bank rate is higher.
Module 7 · Try it
In early years, your EMI is mostly interest.
Module 7 · Credit and debt
Your credit score is your price tag for borrowing.
Bureaus like CIBIL score you from 300 to 900. Higher scores get loans faster and cheaper.
Raises it
Paying on time. Low card usage. Long history.
Lowers it
Missed EMIs. Maxed cards. Many new loan applications.
Module 7 · Credit and debt
Compounding works for you, or against you.
Good debt buys something that earns more than its interest. Bad debt funds consumption at high rates. Card balances in India often cost 36 to 45% a year.
Module 8 · Governments
Governments tax, spend, and borrow the gap.
Module 8 · Governments
India now spends more on interest than on building.
of Union spending goes to interest in 2026 to 27. That's about 40% of revenue receipts.
of US federal spending went to interest in FY26: $1.05 trillion.
Union Budget 2026 to 27 (PRS); US Treasury data. Capital spending includes some defence capital outlay.
Module 8 · Governments
Two levers run every economy.
Decided by the government and Parliament in the Budget. Builds roads, pays salaries, transfers to states, funds welfare.
Decided by the central bank. Speeds up or slows down borrowing across the whole economy.
When they push the same way, the effect is strong. In 2020 both pushed hard: global debt rose $35 trillion in one year.
Module 9 · The real economy and assets
Money circles. Goods and services flow back.
Firms pay wages. Households spend wages on products and services. Firms earn revenue and pay wages again. Money is the blood; work and goods are the body.
Module 9 · The real economy and assets
An asset pays you, or is scarce. Ideally both.
A slice of a company
Pays: share of profits, as dividends and growth.
A loan you make
Pays: fixed interest. Falls in value when rates rise.
Land plus a building
Pays: rent, plus scarcity of land. Usually bought with debt.
Scarce metal
Pays: nothing. Holds value through scarcity and trust.
A loan to your bank
Pays: interest. Often less than inflation after tax.
Your own engine
Pays: profit. The highest risk and highest upside.
Module 9 · The real economy and assets
When rates fall, asset prices rise.
An asset's price is what its future income is worth today. Lower rates make that income worth more. Slide the rate.
Module 9 · The real economy and assets
Debt magnifies property gains, and losses.
Buy a ₹1 crore flat with ₹20 lakh of your own and ₹80 lakh of loan. Every move in price lands on your ₹20 lakh first.
Module 9 · The real economy and assets
Where the world's wealth sits.
*Notional face value; actual market value about $21.8T. Layers overlap, so don't add them. Sources: IIF, Savills, BIS, WFE based data, 2025 to 2026.
Module 9 · The real economy and assets
Inflation quietly shrinks cash.
India's inflation was 5.54% in September 2026. Rule of 72: divide 72 by the rate to see how fast prices double.
Module 10 · The big players
Eight players move the world's money.
Central banks set the price. Governments tax and borrow. Banks create credit. Asset managers, pension funds and sovereign funds decide where savings go. Rating agencies grade the borrowers.
Module 10 · The big players
One firm manages $15.5 trillion of other people's money.
BlackRock doesn't own that money. Pension funds, insurers and savers do. But it invests it, and often votes the shares.

BlackRock Q3 2026 results. Index funds made it cheap for anyone to own the whole market, and concentrated voting power in a few managers.
Module 10 · The big players
India's savers are moving into markets.

Every SIP is a wage earner stepping from the wage loop into the capital loop. Module 11 explains why that matters.
Module 10 · The big players
Who decides what.
| Interest rates | RBI MPC, US FOMC, ECB Governing Council |
| Taxes and spending | Finance ministry and Parliament, through the Budget |
| Who gets a loan | Bank credit teams, guided by credit scores and RBI rules |
| Where savings are invested | Asset managers, pension and insurance funds, and you |
| What a country pays to borrow | Bond investors, guided by S&P, Moody's and Fitch ratings |
| The value of the rupee | The currency market, with the RBI buying or selling dollars to smooth moves |
Module 11 · Who owns what
The top 10% own three quarters of everything.
Module 11 · Who owns what
1.5% of adults hold almost half of all wealth.
58 million millionaires hold $250.6 trillion. 1.62 billion adults with under $10,000 hold $3.2 trillion between them.
UBS Global Wealth Report 2026, 56 markets.
Module 11 · Who owns what
Two loops. One cycles. One compounds.
The wage loop
Money passes through. Each lap ends near where it began.
The capital loop
Gains stay invested. Loans aren't income, so they aren't taxed.
Module 11 · Who owns what
New money reaches some people first.
It lands with banks, bond markets and borrowers who have collateral. They buy assets before prices adjust. Wages catch up last. This is the Cantillon effect, described in the 1730s.
Module 11 · Who owns what
When capital grows faster than wages, gaps widen.
Economist Thomas Piketty's long run data: returns on capital (r) near 4 to 5% a year; economies and wages (g) 1 to 2% in real terms.
Critics argue much of the effect comes from housing scarcity, and that broad ownership through funds narrows it. Both views are in the sources.
Module 12 · How to think about money
Earn. Keep. Own.
Earn
Income is the fuel. Skills that are scarce earn more.
Keep
Spend less than you earn. Avoid costly debt. Keep a cushion.
Own
Move the surplus into assets that produce income or grow.
Wage earners who do step 3 for long enough join the capital loop.
Module 12 · How to think about money
Only the return above inflation counts.
Real return = return after tax minus inflation. Below zero, your money is shrinking even as the number grows.
Module 12 · Try it
Same saver. Different home for the money.
Smooth returns assumed; real markets fall 30 to 50% at times. Illustration, not advice.
Module 12 · How to think about money
Physical or financial? Know the trade offs.
| Physical: property, gold | Financial: funds, stocks, bonds | |
| Selling fast | Slow. Weeks to months | Fast. Usually days |
| Minimum size | Lumpy. Lakhs to crores | Small. A ₹500 SIP works |
| Income | Rent for property, none for gold | Dividends, interest |
| Debt use | Easy to borrow against property | Possible, riskier to use |
| Costs | Stamp duty, upkeep, storage | Fund fees, taxes on gains |
| Feel | Tangible, trusted across generations | Abstract, prices move daily |
Module 12 · How to think about money
Six durable principles.
Keep a cushion
Months of expenses in cash, so a shock never forces a sale.
Kill costly debt
Paying off a 40% card is a guaranteed 40% return.
Own producers
Assets that earn income beat assets that only sit.
Spread risk
No single asset, sector or country should sink you.
Time over timing
Compounding needs years. Guessing tops rarely works.
Know what you own
If you can't explain how it pays you, don't buy it.
General education, not personal financial advice.
Module 13 · The future of money
Next: money with rules built in.
98% of world GDP. A direct claim on the central bank, held in a phone wallet. Rules can be coded in, such as expiry dates on subsidies. India's e₹ and China's e-CNY lead.
Private digital dollars backed mostly by US Treasury bills. Tether's USDT holds ~59% and Circle's USDC ~24% (June 2026).
Both raise the same questions: who can see your payments, and who can switch them off.
Module 13 · The future of money
Right now: inflation is back, rates are rising.
Sept 2026, food 7.74%
hiked 7 Oct 2026
hiked 16 Sept 2026
mid 2026, a record
Higher rates make debt costlier for everyone, from your EMI to the government's interest bill.
Module 13 · Try it
Compound today's numbers forward.
Not a forecast. Just arithmetic. Recent pace: money 7.7% a year, debt about 9% in 2025.
