Money is not the paper in your wallet and it is not the number glowing inside your banking app. It is a system of trust, credit, prices and promises. Once that clicks, banks stop looking mysterious, inflation makes more sense, interest stops feeling like random percentage math, and wealth becomes much easier to measure honestly.
My quick take Read this first
Most of us spend decades using money before anyone explains what is actually happening underneath it.
Here is the version I would want a teenager, a parent and a retiree to understand: money works because we trust it will be accepted tomorrow. Banks mostly move and create electronic deposits, not piles of notes. Interest is the price attached to time and credit. Inflation changes what each unit of money can buy. And wealth is not income — it is what you own after subtracting what you owe.
Keep those ideas in your head and a surprising amount of personal finance becomes less confusing.
On September 1, 2026, The Kathmandu Post reported that a shopper in Mulpani had paid Rs100 for a kilogram of onions one week and Rs140 the next.
Same rupee. Same basic purchase. Very different buying power. That is money in real life. Read the reported example.
We talk about money as if it is an object. “I have money.” “I need money.” “The bank has my money.”
Useful phrases. Not quite the full picture.
Open your banking app. Most of what you call money is not sitting in a labelled box waiting for you. It is an electronic bank deposit — a claim you can use to make payments and, under normal conditions, exchange for cash.
The Bank of England's 2025 explainer says the vast majority of money in the UK is held electronically rather than as notes and coins. The exact mix differs from country to country, but the basic lesson travels well: modern economies run mostly on digital balances and trusted payment systems, not physical cash changing hands.
So what is money, actually?
Strip away the jargon and money does a few jobs for us.
It lets a shop put a price on rice, rent, a phone and an hour of labour using the same measuring stick. It lets you sell something today without having to find someone who can immediately barter exactly what you want. And it lets you carry purchasing power from today into the future.
Economists give those jobs formal names: unit of account, medium of exchange and store of value. The IMF also recognizes money's role in settling payments that happen over time.
A banknote has very little practical value as paper. Its usefulness comes from the fact that people, businesses, banks and the state recognize it inside a functioning monetary system.
The same is true of the balance on your phone screen. You trust that Rs10,000 in your account can be transferred, withdrawn or spent as Rs10,000.
Your bank balance is real money. It just is not cash.
This is where people often picture banking incorrectly.
Deposit Rs5,000 in cash and, yes, your bank owes you that deposit. But the modern banking system is much bigger than cash deposits being physically shuffled from one customer to another.
Commercial bank deposits themselves function as money. You pay rent with them. Buy groceries with them. Send them across the country in seconds.
The Bank of England describes modern money as including central-bank money and commercial-bank money. Cash is central-bank money available to the public. Commercial-bank deposits are private money issued by banks and are expected to exchange at par with central-bank money.
Picture the system in three layers
Cash: notes and coins you can hold.
Your deposit: the spendable balance your commercial bank owes you.
Bank reserves: central-bank money commercial banks use to settle payments among themselves and meet liquidity needs.
You do not need to think about bank reserves when buying tea. Banks do. That hidden settlement layer helps make the visible payment layer feel boring and instant — which is exactly what a payment system should feel like.
The strange part: banks can create new money when they lend
This sounds fake the first time you hear it. It is not.
When a commercial bank approves a loan, it can credit the borrower's deposit account. The loan appears as an asset on the bank's balance sheet; the new deposit appears as a liability. New deposit money has entered the economy.
The Bank of England puts it plainly: commercial banks create most of the money used by households and businesses when they extend loans.
Suppose a bank approves a Rs1,000,000 business loan. The borrower now has a Rs1,000,000 deposit to spend and a Rs1,000,000 debt to repay.
Notice what did not happen. The borrower did not become Rs1,000,000 wealthier simply because the account balance rose. There is an asset and a matching liability.
Can banks just create unlimited money?
No.
Banks face capital requirements, liquidity requirements, regulation, funding and settlement constraints, credit risk, profitability questions and the basic problem of finding borrowers who can repay.
A reckless loan can create a deposit today and a loss tomorrow. Banking licenses come with rules precisely because the ability to create deposit money is economically important.
Central banks influence this process too. Interest-rate policy changes the price of borrowing and the incentives to lend, borrow and save. Regulation and financial-stability policy add further constraints.
The part almost nobody tells you: money can be destroyed too
If bank lending can create deposit money, the obvious next question is: where does that money go when the loan is repaid?
In the simplest case, principal repayment works in reverse. Your deposit balance falls and the bank's loan asset falls with it. The deposit money used to repay the principal is extinguished from the banking system.
The Bank of England explains this directly: banks create deposits when they lend, and those deposits are deleted as the corresponding loans are repaid.
This is one reason the money supply is not a one-way escalator. New lending can expand bank deposits. Debt repayment can contract them. Banks buying assets from non-banks can create deposits; banks selling assets to non-banks can remove deposits. Central-bank asset purchases can alter the composition of money and financial assets too.
This distinction matters because it stops us thinking of "the money supply" as a fixed pile. In a modern credit economy, part of the money stock expands and contracts with balance sheets.
If banks create deposits, why do they still need reserves and funding?
This is where a shallow explanation usually breaks down.
A bank can create a deposit when it lends. But once the borrower spends that deposit, the payment may leave the bank.
Suppose Bank A makes you a loan and you use the money to pay a seller who banks with Bank B. Bank A now has to settle with Bank B. That settlement happens using central-bank money — reserves — or through arrangements that ultimately rely on the central bank's settlement system.
So a bank does not need to find an existing deposit before it creates a loan in the simplistic "saver gives money to bank, bank passes it on" sense. But it absolutely cares about funding, liquidity, reserves, capital and the possibility that deposits move elsewhere after lending.
Loan creation and payment settlement are two different moments
Moment 1: the bank grants the loan and creates a matching deposit.
Moment 2: the borrower spends the deposit. If the receiver uses another bank, reserves may need to move between banks.
Constraint: the lending bank still has to remain liquid, solvent, adequately capitalized and profitable.
This also explains why the old textbook "money multiplier" story can be misleading if taken literally. Banks do not generally wait for a fixed quantity of reserves and then multiply them mechanically into loans. Modern central banks usually steer short-term interest rates and supply reserves as needed for payment-system stability, while banks decide whether to lend based on capital, risk, expected return, funding conditions and credit demand.
The Bank for International Settlements has emphasized the same point: bank lending is not simply constrained by a pre-existing stock of central-bank reserves. The constraints are broader and more economic than that.
Interest is the price attached to time
People often talk about interest as if it were a punishment. Sometimes it certainly feels like one.
At a basic level, though, interest solves a real problem: one person gets to use money now while another person gives up the use of that money, accepts risk or provides credit.
Borrow Rs100,000 today and repay it over time. The lender usually expects compensation for waiting, for the chance you do not repay, for inflation and for the fact that the lender could have used that money elsewhere.
That compensation shows up as interest and, often, fees.
What does a central bank rate have to do with your loan?
Central banks do not normally set every mortgage, credit-card or business loan rate one by one.
They influence the wider cost of money. Policy rates affect funding conditions and financial-market rates, which then flow — imperfectly and with delays — into borrowing and saving rates across the economy.
Your actual rate still depends on the product, lender, credit risk, collateral, competition and local financial system.
The interest rate you see is not always the interest rate that matters
A loan says 8%. Inflation is 5%. Is the economic burden really 8%?
Not quite.
Economists distinguish between a nominal interest rate and a real interest rate. The nominal rate is the percentage printed on the loan or deposit. The real rate adjusts for inflation.
A rough shortcut is:
So a 7% nominal return during 5% inflation is roughly a 2% real return before taxes and fees. A 4% savings return during 6% inflation can leave purchasing power falling even though the account balance is rising.
The precise relationship is multiplicative rather than simple subtraction, especially when rates are high, but the shortcut is useful for everyday reasoning.
This is one reason borrowers and savers can experience the same interest rate very differently depending on inflation.
How does one central-bank rate end up affecting rent, jobs and your loan?
Central banks change one policy rate. The whole economy does not move in one neat step.
The process is called monetary-policy transmission, and it works through several channels at once.
| Channel | What changes | Why households feel it |
|---|---|---|
| Interest-rate channel | Borrowing and saving rates | Loans, mortgages, deposits and investment decisions become more or less attractive. |
| Bank-lending channel | Banks' funding costs and willingness to lend | Credit can become easier or harder to obtain even before every posted rate moves. |
| Asset-price channel | Bond, equity and property valuations | Financing conditions and household wealth can influence spending and investment. |
| Expectations channel | Beliefs about future inflation and rates | Firms set prices and wages partly around what they expect next. |
| Exchange-rate channel | Currency value | Imported goods, fuel, equipment and foreign-currency debts can become cheaper or more expensive. |
That is why monetary policy feels slow and uneven. A central-bank decision can hit a variable-rate borrower quickly, a fixed-rate borrower only when refinancing arrives, a renter indirectly through landlords and construction costs, and a business through credit, demand and exchange rates.
The BIS describes transmission in similar terms: policy changes first affect financial variables such as money-market rates, deposit rates, lending rates and credit supply; those changes alter aggregate demand and eventually inflation.
Inflation is what happens when the measuring stick moves
Go back to those onions in Mulpani.
Rs100 did not physically shrink between one week and the next. The purchasing power attached to Rs100 changed relative to that product.
One price can jump because of a supply shortage. Inflation is broader: a sustained rise in the overall price level across a basket of goods and services.
Nepal Rastra Bank's data show how uneven this can be. In mid-May 2026, year-on-year consumer inflation was 5.04%, while fruit was up 18.60% and ghee and oil 13.99% in the bank's published sub-category data. A household buying more of the fast-rising items can feel a squeeze very different from the headline average.
That is why leaving Rs100,000 untouched for years does not guarantee that it preserves the same standard of living.
Nominal value and real purchasing power are different things. Personal finance gets much easier once you stop mixing them up.
Inflation can become partly about what people expect next
Inflation is not only about today's shortages or yesterday's money creation.
Expectations matter because many economic decisions are forward-looking.
A worker negotiating next year's salary cares about next year's prices. A landlord setting a lease thinks about future costs. A business pricing a long-term contract tries to estimate wages, energy and materials. A bond investor cares about the purchasing power of future repayments.
If everyone becomes convinced that high inflation will persist, that belief can influence wage demands and price setting. Central banks therefore care deeply about keeping inflation expectations anchored.
The IMF notes that expectations are one channel through which monetary policy affects actual inflation. Credible policy can influence the wage and price decisions people make before the inflation actually happens.
Why is one currency worth more than another?
There is no single knob called "the exchange rate."
Currency values reflect the supply of and demand for currencies, which are influenced by interest-rate differences, inflation expectations, trade flows, investment flows, political and economic confidence, global risk appetite and the exchange-rate regime itself.
Higher interest rates can, all else equal, make a currency more attractive to investors seeking returns. But "all else equal" is doing a lot of work. A country can have high interest rates precisely because inflation or financial risk is high, which can push the other way.
For households, the important part is exchange-rate pass-through.
If your currency weakens against the currency used to buy imported fuel, machinery, medicine or food, those imports can become more expensive in domestic currency. That can feed into consumer prices.
For countries with foreign-currency debt, exchange-rate moves can also change the domestic burden of repayment.
The BIS continues to treat the exchange rate as an important monetary-policy transmission channel, especially in open and emerging economies.
Government spending and central-bank money are not the same policy
This distinction gets mangled constantly online.
Fiscal policy is mainly about government spending, taxation and borrowing.
Monetary policy is mainly about the central bank's tools for influencing financial conditions, inflation and economic activity — usually policy rates, liquidity operations and, in some periods, asset purchases.
The two can interact strongly. A government can run a large deficit while a central bank raises rates. A government can tighten spending while a central bank cuts rates. Both affect total demand, but through different institutions and mechanisms.
When people say "the government printed money," they often collapse several different balance-sheet operations into one phrase. Sometimes the central bank is creating reserves while buying assets. Sometimes the treasury is issuing debt to finance spending. Sometimes banks are creating deposits by lending. Those are related monetary events, but they are not the same transaction.
Quantitative easing: more reserves does not mean banks hand out the same amount in new loans
Quantitative easing, or QE, is often described as "printing money." That shorthand hides the actual mechanics.
In a typical QE operation, a central bank purchases securities and pays by creating central-bank reserves. The seller gives up one financial asset and receives another form of highly liquid money or a bank deposit backed by the settlement of that transaction.
The ECB explains QE as an asset-purchase process that raises bond prices, lowers a range of interest rates and makes financing conditions easier. The transmission is through yields, portfolios, expectations, credit and spending — not through a mechanical rule that every new reserve dollar, pound or euro must be multiplied into a fixed amount of bank lending.
That is a crucial advanced point: reserves are not the same thing as household bank deposits.
Only eligible institutions hold reserve accounts directly at the central bank. Households generally hold commercial-bank deposits and cash.
A central bank can create reserves. Commercial banks can create deposits through lending. The two forms of money connect through the payment and banking system, but they sit on different balance sheets.
Money is not wealth
A high salary can make you look rich. A large bank balance can make you feel rich. Neither tells the whole story.
The OECD's definition of household net worth is refreshingly simple: assets minus liabilities.
Someone earning Rs300,000 a month with heavy debt and little ownership may have less net wealth than someone earning far less who owns productive assets and owes almost nothing.
Income is a flow. Wealth is a stock.
Income is what comes in over a period. Wealth is what remains on the balance sheet after subtracting what you owe.
| Concept | Plain-English meaning | Question to ask |
|---|---|---|
| Income | Money flowing to you over time | What am I earning? |
| Money / cash | Liquid purchasing power available for payments | What can I spend or access now? |
| Assets | Things of economic value you own | What do I own? |
| Liabilities | Financial obligations you owe | What must I repay? |
| Net worth | Assets minus liabilities | What is left after the debts? |
That distinction matters because the goal of wealth building is not to collect the largest possible pile of cash. Cash has jobs: bills, emergencies, near-term spending, optionality.
Long-term wealth usually depends on what you own, what those assets can produce or become worth, how much debt sits against them, the risks you take and how long you stay in the game.
Compounding does not care whether it is helping you or hurting you
Compound interest is just interest building on previous interest.
Investor.gov gives the classic example: $100 earning 5% becomes $105 after one year and $110.25 after two because the second year's interest is earned on $105, not only the original $100.
Lovely when you are earning it. Less charming when you are paying it.
High-cost debt can compound against you in the same mathematical spirit, especially when unpaid interest or fees are added to balances. Investment growth can compound for you, but returns are uncertain and can be negative. There is no guaranteed magic percentage.
This is why a seemingly small difference in interest rate can matter over a long period, and why fees deserve more attention than they usually get.
Why printing more money is not a shortcut to making everyone richer
This question usually arrives five minutes after someone learns that money can be created.
If creating money were the same as creating wealth, every country could solve poverty by increasing account balances.
Real wealth comes from the goods, services, skills, infrastructure, businesses, technology, land, homes and productive capacity those monetary claims can buy.
More money chasing the same limited amount of goods does not magically create more goods. Depending on the circumstances, it can push prices higher.
Monetary policy is more complicated than the slogan “printing causes inflation,” because the effect depends on credit, demand, supply, expectations, interest rates, spare capacity and many other moving parts.
Still, the core distinction is worth keeping: creating money is not the same thing as creating economic resources.
Forget a complicated spreadsheet. Do this money check tonight.
Open a blank note on your phone.
Write down your accessible cash and bank deposits. Under that, list what you owe. Then write the major assets you actually own. Finally, note your monthly income and the amount that usually survives after recurring expenses.
Four lines. Maybe ten minutes.
You will already know more about your financial position than someone who only watches their account balance.
Wealth building becomes much less mystical when you treat it as a balance sheet plus time.

Is the money in my bank account actually my money?
Your bank deposit is a claim on the bank that you can normally use for payments or convert into cash. It functions as money even though it is not a pile of notes physically stored in your name.
Do banks lend out the exact money other customers deposited?
That is an oversimplification. In modern banking, commercial banks can create a new matching deposit when they make a loan. They are still constrained by capital, liquidity, regulation, risk, profitability and settlement needs.
Does a bank create wealth when it creates money?
No. When a loan creates a new deposit, it also creates a debt. New purchasing power appears, but the borrower's liability appears with it.
Why does inflation make savings feel smaller?
The nominal balance may stay the same while prices rise. That means the same amount of money buys fewer goods and services, so its real purchasing power falls.
Is interest always bad?
No. Interest can be a cost to a borrower and income to a saver or investor. Whether a particular rate is attractive or harmful depends on the product, risk, fees, inflation, alternatives and your circumstances.
What is the simplest definition of wealth?
A useful household definition is net worth: the value of assets minus outstanding liabilities. Income matters, but income and wealth are not the same thing.

Editorial note: banking systems, reserve frameworks, deposit insurance, exchange-rate regimes, monetary-policy tools and financial products differ by country. This article explains modern credit-money mechanics using mainstream central-bank and international-institution sources; some institutional details vary across jurisdictions.

Final thought: money looks simple because the interface is simple. Tap. Pay. Borrow. Save. Underneath that simplicity sits a network of trust, bank balance sheets, central-bank money, interest rates and changing prices. You do not need to become an economist. You just need to know which number you are looking at — income, cash, debt, an asset, or actual net wealth.
