Economics vocabulary / Lesson 03
Money, credit & central banks
Understand the language behind “Who Creates the Money, and Who Pays the Price?” Start with the people and institutions, then follow a loan, a bond and a central-bank purchase.
Created by Denis M., British English teacher.
Separate the decision-makers
A household applies for a mortgage. The government plans a new hospital. The central bank adjusts policy. Each decision belongs to a different part of the system.
commercial bank
A bank that provides services such as accounts, payments and loans.
“The commercial bank approved a business loan.”
Understand it more deeply
Say it: com-MER-cial BANK
Capitals show stress; this is a reading guide, not phonetic spelling.
Think of the bank where a household or business holds an account. It assesses borrowers and provides financial services. It operates within regulation and needs to manage funding, liquidity, capital and credit risk. “Commercial” distinguishes this role from that of the central bank.
Use it naturally
a commercial-bank loan · commercial-bank deposits
Who normally decides whether to approve your mortgage application?
Show answer & why
The lending commercial bank, using its lending criteria.
central bank
An institution responsible for monetary policy and key parts of the monetary system.
“The central bank raised its policy interest rate.”
Understand it more deeply
Say it: CEN-tral BANK
Capitals show stress; this is a reading guide, not phonetic spelling.
A central bank can set policy rates and provide accounts for eligible banks. Its exact responsibilities vary by country or currency area. It is not normally where you open a personal current account. An independent central bank still operates under a legal mandate; independence does not mean unlimited power.
Use it naturally
central-bank policy · central-bank independence
Is the central bank normally the place to open a personal current account?
Show answer & why
No. That is normally a commercial-bank service.
monetary policy
Central-bank decisions that influence money, interest rates and financial conditions.
“Tighter monetary policy can make borrowing less attractive.”
Understand it more deeply
Say it: MON-e-tar-y POL-i-cy
Capitals show stress; this is a reading guide, not phonetic spelling.
Policy rates and asset purchases are examples of monetary-policy tools. Their effects pass through financial markets and the wider economy over time. A policy can aim to support price stability without controlling every price or every lending decision directly.
Use it naturally
tighten monetary policy · loosen monetary policy
A central bank changes its policy interest rate. Which kind of policy is this?
Show answer & why
Monetary policy.
fiscal policy
Government decisions about taxation and spending.
“The government used fiscal policy to support household incomes.”
Understand it more deeply
Say it: FIS-cal POL-i-cy
Capitals show stress; this is a reading guide, not phonetic spelling.
Tax cuts, higher public spending and spending reductions are fiscal choices. Borrowing may finance a gap between spending and revenue. Fiscal and monetary policies can interact, but they are different sets of decisions. Building a hospital is not the same action as a central bank buying a bond.
Use it naturally
expansionary fiscal policy · fiscal support
The government raises a tax and increases school funding. Which policy is changing?
Show answer & why
Fiscal policy.
Follow a loan into an account
In a simplified example, a bank grants Mina a £10,000 loan. Her account gains £10,000, and she owes £10,000. The bank records the loan as an asset and the deposit as a liability.
bank deposit
Money held in a customer’s bank account.
“The loan appeared as a new bank deposit.”
Understand it more deeply
Say it: BANK de-POS-it
Capitals show stress; this is a reading guide, not phonetic spelling.
The deposit is an asset for the customer and a liability for the bank: the bank owes the account holder that amount. “Deposit” names the account balance as well as the act of paying money in. A deposit can arise when a bank lends, rather than from someone delivering cash.
Use it naturally
hold a deposit · deposit money · a deposit balance
From the bank’s perspective, is the customer’s deposit an asset or a liability?
Show answer & why
A liability, because the bank owes money to its customer.
credit creation
The creation of new bank deposits through bank lending.
“Mortgage lending can contribute to credit creation.”
Understand it more deeply
Say it: CRED-it cre-A-tion
Capitals show stress; this is a reading guide, not phonetic spelling.
When a bank makes a loan, it can create a matching deposit. This adds purchasing power and an obligation to repay. Banks face lending, funding and regulatory constraints. Repaying loan principal reduces the outstanding loan and, in the banking system, destroys the corresponding deposit money; interest payments are different.
Use it naturally
bank credit creation · credit expansion
Does creating a £10,000 loan instantly make the borrower £10,000 wealthier overall?
Show answer & why
No. The borrower gains a deposit and an equal debt.
central-bank reserves
Balances that eligible banks hold at the central bank.
“The banks used reserves to settle the payment.”
Understand it more deeply
Say it: CEN-tral-bank re-SERVES
Capitals show stress; this is a reading guide, not phonetic spelling.
When customers of different banks pay each other, banks can settle with central-bank money. Reserves are distinct from customers’ deposit balances. A household does not normally spend reserves at a supermarket. Creating more reserves does not mean households automatically receive or spend the same amount.
Use it naturally
reserve balances · settle in reserves
A customer pays another bank’s customer. Which money can the banks use to settle between themselves?
Show answer & why
Central-bank reserves.
broad money
A measure of money held by the public, including cash and many bank deposits.
“Bank deposits form a large part of broad money.”
Understand it more deeply
Say it: BROAD MON-ey
Capitals show stress; this is a reading guide, not phonetic spelling.
“Broad” means the measure includes more than physical cash. Exact definitions vary across countries and measures. Keep three categories distinct: notes and coins, customer deposits, and banks’ central-bank reserves. An increase in one category does not always produce an equal increase in every other measure.
Use it naturally
the broad money supply · broad money growth
Does broad money mean only printed notes and coins?
Show answer & why
No. It includes many bank deposits and, depending on the measure, other money-like instruments.
Name the obligation correctly
The lender provides credit. The borrower incurs debt. To distinguish private and public debt, identify the borrower, rather than assuming that “public” means the money is visible to everyone.
credit
An arrangement that allows borrowing or payment later.
“The business obtained credit to buy equipment.”
Understand it more deeply
Say it: CRED-it
Capitals show stress; this is a reading guide, not phonetic spelling.
A lender extends credit and a borrower takes on a debt when funds are drawn. A credit limit is permission to borrow up to a maximum, not necessarily a debt already owed. In other contexts, “credit” can mean an entry added to an account; always check how the word is used.
Use it naturally
extend credit · access to credit · a credit limit
A card has an unused £2,000 limit. Does its owner necessarily owe £2,000?
Show answer & why
No. Available credit is different from money already borrowed.
private debt
Debt owed by households and private businesses.
“Mortgages and company loans contribute to private debt.”
Understand it more deeply
Say it: PRI-vate DEBT
Capitals show stress; this is a reading guide, not phonetic spelling.
The classification follows the borrower. A household mortgage is private debt even if the loan is held by a large institution. “Private” does not mean secret. It distinguishes these borrowers from government or other public-sector bodies in a macroeconomic discussion.
Use it naturally
household private debt · private-sector borrowing
A business borrows to expand. In this context, is that private or public debt?
Show answer & why
Private debt, because the borrower is a private business.
public debt
Debt owed by government or the wider public sector.
“Investors hold government bonds as part of public debt.”
Understand it more deeply
Say it: PUB-lic DEBT
Capitals show stress; this is a reading guide, not phonetic spelling.
Government debt can be held by domestic households, overseas investors, banks or a central bank. The identity of the holder does not change who owes the money. A central bank buying an existing government bond changes its holder; the government’s obligation is not simply cancelled.
Use it naturally
issue public debt · service government debt
A household owns a government bond. Is the government’s debt now private debt?
Show answer & why
No. The government remains the borrower.
budget deficit
Spending above revenue during a stated period.
“The annual budget deficit required additional financing.”
Understand it more deeply
Say it: BUD-get DEF-i-cit
Capitals show stress; this is a reading guide, not phonetic spelling.
A deficit is a flow; debt is a stock. In a simplified example, £100 of revenue and £115 of spending leave a £15 deficit. Borrowing can finance that gap. Reducing the deficit from £15 to £5 still leaves spending above revenue, so debt may continue to rise.
Use it naturally
finance a deficit · run a deficit
A deficit becomes smaller but stays positive. Does that necessarily reduce total debt?
Show answer & why
No. A smaller deficit can still require new borrowing.
Understand the promise inside a bond
Consider a fictional fixed-rate bond with a £100 face value. It pays £5 each year and repays £100 at maturity. The price investors pay for that bond can change.
government bond
A tradable government borrowing instrument with promised payments.
“The government issued bonds to raise funds.”
Understand it more deeply
Say it: GOV-ern-ment BOND
Capitals show stress; this is a reading guide, not phonetic spelling.
At issue, investors lend money under the bond’s terms. Later, investors may trade the bond with each other. Buying an existing bond from another investor does not itself hand new money to the government. UK government bonds are commonly called gilts.
Use it naturally
issue bonds · buy a government bond · the bond market
You buy an existing government bond from a pension fund. Who receives your payment?
Show answer & why
The pension fund selling the bond, not directly the government.
principal
The original loan amount or the face amount repayable on a bond.
“The borrower repaid part of the principal.”
Understand it more deeply
Say it: PRIN-ci-pal
Capitals show stress; this is a reading guide, not phonetic spelling.
Principal is different from interest, the charge for borrowing. For the example bond, the £100 promised at maturity is the principal. Its market price can be above or below £100. “Principal” also means main or most important; “principle” means a rule or belief.
Use it naturally
repay the principal · principal and interest
You pay £110 for a bond promising £100 at maturity. Is its principal automatically £110?
Show answer & why
No. Its face amount remains £100 under the stated terms.
coupon
The interest payment specified by a bond’s terms.
“The bond pays an annual coupon of five pounds.”
Understand it more deeply
Say it: COU-pon
Capitals show stress; this is a reading guide, not phonetic spelling.
For our fixed-rate bond, the £5 annual coupon stays the same even if the market price changes. Some bonds have variable or inflation-linked payments, and some pay no periodic coupon. Start with the fixed example before extending the comparison.
Use it naturally
a fixed coupon · annual coupon payments
Our fixed-coupon bond rises in market price. Does its £5 coupon automatically rise?
Show answer & why
No. Its fixed contractual coupon remains £5.
bond yield
A measure of the return on a bond relative to its price.
“Bond yields fell as bond prices rose.”
Understand it more deeply
Say it: BOND YIELD
Capitals show stress; this is a reading guide, not phonetic spelling.
For current yield, divide the annual coupon by the current market price. A £5 coupon on a £100 price gives 5%; on a £125 price it gives 4%. Yield to maturity is more complete: it also accounts for repayment value, time and the remaining payments. A bond’s coupon and yield are not interchangeable.
Use it naturally
bond yields rise · lower yields
A fixed £5 coupon bond costs £125. What is its current yield?
Show answer & why
4%: £5 divided by £125. This is current yield, not yield to maturity.
See what QE actually changes
In a simplified QE purchase, the central bank buys an existing government bond from a pension fund. It credits reserves to the fund’s bank, which credits the fund’s deposit account. The fund exchanges a bond for a deposit.
quantitative easing (QE)
Central-bank asset purchases funded with newly created reserves.
“Quantitative easing can ease financial conditions.”
Understand it more deeply
Say it: QUAN-ti-ta-tive EAS-ing · Q E
Capitals show stress; this is a reading guide, not phonetic spelling.
QE can support bond prices and put downward pressure on yields and wider borrowing costs. An investor selling a bond receives a different asset, not a free payment without giving something up. Effects depend on conditions and subsequent decisions. QE does not guarantee a fixed amount of consumer spending or inflation.
Use it naturally
introduce QE · expand asset purchases
In the example, what does the pension fund give up in exchange for the deposit?
Show answer & why
Its government bond. QE is an asset purchase, not simply a gift.
quantitative tightening (QT)
Reducing the stock of assets held under central-bank purchase programmes.
“The central bank reduced its bond holdings through quantitative tightening.”
Understand it more deeply
Say it: QUAN-ti-ta-tive TIGHT-en-ing · Q T
Capitals show stress; this is a reading guide, not phonetic spelling.
A central bank can sell bonds or allow holdings to mature without replacing them. QT reduces the purchase programme’s holdings; its effects depend on how it is implemented and on market conditions. It is not identical to raising the policy rate, and its economic effects need not mirror QE exactly.
Use it naturally
begin QT · reduce bond holdings
A central bank lets purchased bonds mature without reinvesting. Which process does this illustrate?
Show answer & why
Quantitative tightening.
asset-price inflation
Increases in prices of assets such as houses, land or shares.
“Asset-price inflation benefited some existing owners.”
Understand it more deeply
Say it: AS-set-price in-FLA-tion
Capitals show stress; this is a reading guide, not phonetic spelling.
A house is an asset; groceries are consumer goods. Their prices can move differently. Higher asset prices can increase owners’ wealth while making entry harder for new buyers. Do not assume that a rise in share prices proves the same increase in the cost of everyday essentials.
Use it naturally
rising asset prices · housing-market inflation
House prices rise sharply but grocery prices hardly change. Which concept is most directly illustrated?
Show answer & why
Asset-price inflation, rather than an equivalent rise in consumer prices.
debt-service burden
The pressure that required debt payments place on income or revenue.
“Refinancing at a higher rate increased the debt-service burden.”
Understand it more deeply
Say it: DEBT-SER-vice BUR-den
Capitals show stress; this is a reading guide, not phonetic spelling.
Debt service includes scheduled interest and principal repayments. If monthly debt payments rise from £300 to £500 while income stays at £2,000, the payment share rises from 15% to 25%. Borrowers have less room for other spending. Timing and loan terms determine how quickly rate changes affect them.
Use it naturally
a heavier debt-service burden · service a debt
Income is unchanged but required loan payments rise. What becomes heavier?
Show answer & why
The debt-service burden.
Read the strongest claims carefully
The extension asks who should carry responsibility. These final expressions help you analyse the argument without confusing a mechanism, a risk and a proven outcome.
fiscal dominance
Government financing needs constraining monetary-policy choices.
“Analysts warned that fiscal dominance could weaken inflation control.”
Understand it more deeply
Say it: FIS-cal DOM-i-nance
Capitals show stress; this is a reading guide, not phonetic spelling.
Imagine a central bank needs to tighten policy for price stability, but pressure to keep government financing affordable prevents it from doing so. That illustrates the concern. High debt alone does not establish fiscal dominance; look for evidence that financing needs are subordinating monetary-policy objectives.
Use it naturally
a risk of fiscal dominance · resist fiscal pressure
A government has high debt. Is that fact alone proof of fiscal dominance?
Show answer & why
No. You need evidence that fiscal financing needs constrain or subordinate monetary policy.
dollar-denominated debt
Debt whose amount and payments are specified in US dollars.
“A weaker local currency increased the cost of dollar-denominated debt.”
Understand it more deeply
Say it: DOL-lar de-NOM-i-na-ted DEBT
Capitals show stress; this is a reading guide, not phonetic spelling.
A business earning local currency must obtain dollars to make its payments. If one dollar costs four local units, a $100 payment costs 400. If one dollar later costs five units, it costs 500. The dollar payment is unchanged, but the local-currency cost rises unless protection such as matching dollar income offsets it.
Use it naturally
repay dollar-denominated debt · currency exposure
A $100 payment stays fixed while the local currency weakens against the dollar. What can rise?
Show answer & why
Its cost in local currency.
private credit
In investment markets, lending negotiated outside banks and public bond markets.
“The company borrowed from a private credit fund.”
Understand it more deeply
Say it: PRI-vate CRED-it
Capitals show stress; this is a reading guide, not phonetic spelling.
This specialised meaning often refers to non-bank funds lending directly to businesses. It is narrower than all private-sector borrowing. An ordinary bank mortgage creates private debt but is not usually called a private-credit investment in this sense. Also distinguish public credit markets, where bonds are traded, from public debt owed by governments.
Use it naturally
a private credit fund · direct lending
Is every household bank mortgage part of the private-credit fund market?
Show answer & why
No. Private debt is a broader category than private credit in this investment-market sense.
liquidity
Access to money, or the ease of turning an asset into spendable funds.
“The company needed liquidity to meet this month’s payments.”
Understand it more deeply
Say it: li-QUID-i-ty
Capitals show stress; this is a reading guide, not phonetic spelling.
A firm may own valuable property yet lack cash for a bill due today. Funding liquidity concerns meeting payments. Market liquidity concerns buying or selling an asset without a large price impact. Liquidity problems and insolvency are different: insolvency concerns an inability to meet obligations in a deeper financial sense, not simply the timing of available cash.
Use it naturally
provide liquidity · a liquidity shortage
A valuable building cannot be sold quickly enough to pay tomorrow’s bill. What immediate problem can arise?
Show answer & why
A liquidity shortage. The building’s value does not automatically provide cash on time.
Try it: the same coupon, a different yield
This fictional bond pays a fixed £5 each year. Change its market price and compare the current yield.
Current yield = annual coupon ÷ current price × 100. This deliberately simplified measure excludes the gain or loss at maturity.Annual coupon stays at £5
Keep these distinctions in view
Money creation ≠ instant wealth
A bank loan creates a deposit and a repayment obligation together.
Reserves ≠ your current account
Reserves belong to eligible institutions at the central bank; your deposit is at your commercial bank.
QE ≠ cancelled government debt
Buying an existing bond changes who holds it. The government still owes the payments.
Public debt ≠ public credit markets
Public debt identifies a government borrower; public credit markets can trade government or corporate bonds.
Return to “Who pays the price?”
Give a 90-second explanation for someone with no economics background. Connect credit creation, QE and debt-service burden. State one possible benefit, one possible cost and one reason that “QE caused all inflation” would be too strong.
- Explain three target expressions in plain English.
- Distinguish a bank loan from a QE purchase.
- Use can, may or depends where the outcome is conditional.
- Name one alternative factor to investigate.
Read a model response
Commercial-bank lending can create new deposits and private debt. A central bank can also use QE to buy financial assets with newly created reserves, which can ease borrowing conditions. These measures may support spending and investment, but they do not create unlimited real resources. If prices rise and interest rates later increase, some borrowers face a heavier debt-service burden. We should also examine supply disruptions, energy costs and government policy before assigning all responsibility to QE.
