Financial Markets and Instruments: What They Do and Why They Matter

Learning objectives

By the end of this chapter, you should be able to:

• Explain why financial markets exist and how they connect savers with borrowers.
• Distinguish between money markets (short-term) and capital markets (long-term) and explain their uses.
• Describe how banks and other intermediaries add value, and the risks they can introduce.
• Compare common financial instruments by purpose, return, risk, and liquidity.
• Select suitable instruments for short-term liquidity management and long-term funding in realistic scenarios.
• Record basic transactions involving common financial instruments using double-entry logic and explain the effect on the accounting equation.

Overview & key concepts

Financial markets exist to move funds from parties with surplus cash (savers) to parties that need cash (borrowers). In doing so, they support saving, borrowing, and investment decisions across the economy. Markets also help:

• establish prices through supply and demand,
• provide liquidity (the ability to buy or sell quickly), and
• transfer or spread risk (for example through diversification).

A practical way to organise markets is by time horizon:

• Money markets: short-term investing and borrowing (typically up to one year).
• Capital markets: long-term investing and long-term funding (typically more than one year).

Why this matters in exam-style scenarios

• Working capital decisionsoften involve short-term timing gaps (collecting from customers later than paying suppliers). Money market instruments and short-term bank facilities are common solutions.
• Long-term investment decisions(new plant, expansion, acquisitions) usually require stable funding over several years, which is typically raised in capital markets (debt and/or equity).

Money markets

Money markets are used for short-term cash management. They allow entities to place surplus cash for a short period or borrow to cover temporary cash shortfalls.

Common money market instruments include:

• Treasury bills(short-term government borrowing)
• Commercial paper(short-term company borrowing, usually unsecured)
• Certificates of deposit(bank-issued time deposits; some are tradable)
• Short-term bank deposits and loans

Typical purpose: manage short-term liquidity and working capital timing differences.

Typical accounting impact:

• Borrowing creates afinancial liability(often a current liability).
• Investing creates afinancial asset(often a current asset).

Capital markets

Capital markets support long-term funding and long-term investment. They are commonly split into:

• Primary markets: new securities are issued (new shares, new bonds).
• Secondary markets: existing securities are traded between investors.

Capital market instruments include:

• Bonds / loan notes(debt funding, usually with interest and repayment terms)
• Ordinary shares(ownership funding, no obligation to repay capital)
• Preference shares(classification depends on the contractual terms)

Typical purpose: finance long-term projects, acquisitions, and growth.

Financial intermediaries

Financial intermediaries (banks, funds, insurers, brokers) sit between savers and borrowers. They add value by:

• pooling small deposits into large lendable amounts,
• reducing search, documentation, and dealing costs,
• assessing borrowers and monitoring credit quality,
• providing liquidity and market access, and
• helping manage risk (diversification, maturity transformation, hedging services).

However, intermediaries introduce risks such as:

• credit risk(borrowers default),
• liquidity risk(depositors want cash before loans are repaid),
• interest-rate risk(mismatch between asset and liability repricing), and
• systemic risk(stress spreading across institutions and markets).

Common financial instruments

A quick map: markets → instruments → outcomes

Markets provide the setting in which instruments are created and traded. Instruments generate returns (interest, dividends, gains/losses) but carry risks (credit, interest-rate, liquidity, market). Accounting then determines whether returns appear in profit or loss, outside profit or loss, or directly in equity.

Financial instruments are contractual arrangements that create a financial asset for one party and a financial liability or equity instrument for the other. They are commonly grouped as debt or equity, although some instruments have features of both.

Deposits, bills, and short-term notes (typically money market)

• Purpose:short-term investing or funding.
• Return:interest (or a discount to face value for some instruments).
• Key risks:credit risk, liquidity risk, and (for tradable instruments) interest-rate risk.

Bonds / loan notes (typically capital market)

• Purpose:long-term borrowing for the issuer; income investment for the holder.
• Return:coupon interest plus repayment of principal; possible capital gains/losses if traded.
• Key risks:credit risk, interest-rate risk, liquidity risk.

Ordinary shares (capital market)

• Purpose:permanent funding; investors participate in profits and residual value.
• Return:dividends (if declared) plus share price movements.
• Key risks:business and market risk; returns are not guaranteed.

Preference shares (can be equity or liability)

Preference shares are not automatically “equity” just because they are called shares. Classification depends on substance: if the issuer has an unavoidable obligation to pay cash (for example, mandatory redemption or mandatory cash dividends), the instrument (or part of it) is treated like a liability. If distributions are discretionary and there is no unavoidable redemption obligation, it is more likely to be equity.

Convertible debt (hybrid)

Convertible debt combines a debt-like obligation (interest and principal) with a potential equity outcome (conversion into shares). Whether it is treated as a pure liability or split into components depends on the detailed terms.

Risk, return, and liquidity

Investors generally demand higher returns when taking higher risk. Liquidity also affects required return: the harder it is to sell an instrument quickly at a fair price, the more return investors tend to demand.

Key relationships:

• Higher credit risk → higher expected return (all else equal).
• Higher market yields → lower bond prices (all else equal).
• Better liquidity → often a lower required return (all else equal).

Core theory and frameworks

Recognition of financial instruments

Record a financial asset or liability when the entity enters the contractual rights and obligations of the instrument (that is, when it becomes a party to the contract). For loans and bonds, this often aligns with when cash is advanced or received.

For routine market purchases and sales of traded financial assets (“regular way” trades), questions may specify trade date or settlement date. Entities apply a policy choice for such trades and apply it consistently.

Classification and measurement

Think of classification as answering two questions: why you hold it and what cash flows it can generate. Classification then drives how it is measured and where gains and losses are reported.

Debt instruments (investments in debt)

Use two drivers:

1. How the asset is managed(for example: collect cash flows only; collect cash flows and sell; or another approach such as trading).
2. Whether the contractual cash flows are “plain-vanilla”(often tested as: cash flows are only principal and interest on the outstanding amount).

‘Interest’ here means compensation for time value of money, credit risk and basic lending risks, rather than exposure to equity/commodity-style returns.

A practical summary:

• If managed mainly to collect contractual cash flows and the cash flows are plain-vanilla → measurement commonly follows anamortised cost-styleapproach.
• If managed to collect and sell and the cash flows are plain-vanilla → measurement is typically atfair value through other comprehensive income (FVOCI), while interest is still recognised over time using an effective rate approach.
• If held for trading, managed on another basis, or the cash flows are not plain-vanilla → measurement is typicallyfair value through profit or loss.

For many exam questions, impairment (expected credit losses) may also be relevant for debt measured at amortised cost or FVOCI. ECL affects profit or loss (even where some fair value changes are presented outside profit or loss).

Equity instruments (share investments)

Equity investments are typically measured at fair value through profit or loss, unless an election is made (for qualifying non-trading investments) to present fair value changes outside profit or loss. Under that election, fair value movements are not later recycled through profit or loss on disposal.

Transaction costs: what gets capitalised and what gets expensed?

Only incremental, directly attributable costs are treated as transaction costs of the instrument (for example, broker fees, legal fees, arrangement fees). General administration and staff costs are not.

A clean rule to apply to both assets and liabilities:

• If the instrument isnot measured at fair value through profit or loss, directly attributable transaction costs are included in the instrument’s initial measurement (for issued liabilities this reduces the initial carrying amount; for acquired assets this increases the initial carrying amount) and are then reflected over time.
• If the instrumentis measured at fair value through profit or loss, directly attributable transaction costs are generally expensed as incurred.

Presentation and performance effects

• Debt issued→ financial liability.
• Equity issued→ equity.
• Interest income/expense→ reported in profit or loss.
• Dividends paid→ distributions to owners; they reduce equity and are not an expense.

Double-entry logic and the accounting equation

The accounting equation remains the anchor:

Assets = Liabilities + Equity

Each transaction affects at least two accounts and keeps the equation in balance. Examples:

• Issuing a bond: assets increase (cash), liabilities increase (debt).
• Issuing shares: assets increase (cash), equity increases.
• Paying interest: assets decrease (cash), equity decreases via profit.
• Paying dividends: assets decrease (cash), equity decreases directly.

Borderline cases (why classification can be tricky)

Some instruments contain features (options, conversion terms, contingent settlement, step-up coupons, put/call features) that change the economic substance. A disciplined approach is to identify:

• What cash payments are unavoidable?
• Who controls settlement (issuer or holder)?
• What happens in different scenarios?

A key warning: classification is driven by substance of the contractual terms, not the label or legal form used in the contract.

Convertible debt (how to think about it)

Start by separating what the issuer is obliged to do today from what might happen if the investor chooses. If the terms create an unavoidable obligation to pay cash interest/principal, that portion behaves like debt. If the holder also has a genuine option to convert into the issuer’s own shares, the conversion feature may be treated within equity on initial recognition when the conversion terms follow the usual fixed-for-fixed pattern (a fixed number of shares for a fixed amount).

If conversion is variable or cash-settled at the holder’s option, classification can change.

When conversion occurs, the debt balance is removed and equity increases; the accounting is mainly a reclassification rather than a profit-making event.

Worked example

Narrative scenario

A mid-sized manufacturing company, ABC Ltd, operates in the UK and is planning to expand its operations. The company has a surplus cash balance of £250,000, which it intends to invest for a short period before making a significant capital expenditure. ABC Ltd also plans to issue bonds to finance its expansion and is considering various financial instruments to manage its liquidity and funding needs.

The company has the following transactions and events:

• Surplus cash of £250,000 available for investment.
• Plans to issue £500,000 in bonds with a 5% annual coupon.
• Receives interest income of £2,500 from a short-term bank deposit.
• Pays £1,000 in interest on existing debt.
• Purchases government securities worth £100,000.
• Sells corporate bonds with a carrying amount of £50,000 at a gain of £3,000.
• Issues £200,000 in ordinary shares.
• Converts £50,000 of convertible debt into equity.
• Pays £5,000 in dividends to shareholders.
• Redeems £100,000 of maturing bonds.
• Incurs £2,000 in transaction fees for bond issuance.
• Faces a market yield increase, affecting bond prices.

Required

1. Compute the interest income and interest expense for the period.
2. Prepare journal entries for the bond issuance (including transaction fees) and bond redemption.
3. Calculate and record the gain or loss on the sale of corporate bonds.
4. Record the impact of convertible debt conversion on equity.
5. Explain the effect of a market yield increase on bond prices and illustrate with a simple valuation.

Solution

To avoid role confusion, the solution is split into:

• Issuer-side items(ABC Ltd as the borrower/issuer), and
• Investor-side items(ABC Ltd as the holder of investments).

1) Interest income and interest expense

Investor-side (deposit interest received):

• Interest income: £2,500

Issuer-side (interest paid on existing debt):

• Interest expense: £1,000

2) Bond issuance and redemption (issuer-side)

Assume the £500,000 bonds are issued at par and measured using an amortised cost-style approach. The £2,000 issue fees are directly attributable transaction costs and reduce the initial carrying amount of the liability.

Bond issuance (gross proceeds):
Dr Cash 500,000
Cr Bonds payable 500,000

Transaction fees paid:
Dr Bonds payable 2,000
Cr Cash 2,000

Net effect at issue date:

• Cash increases by £498,000.
• The bond liability’s initial carrying amount is £498,000 (with the difference reflected through a higher effective interest rate over the life of the bond).

Bond redemption (repayment of maturing bonds at par):
Dr Bonds payable 100,000
Cr Cash 100,000

3) Sale of corporate bonds at a gain (investor-side)

Assume the corporate bond investment is measured at fair value through profit or loss, so the gain is recognised in profit or loss.

Carrying amount sold: £50,000
Gain: £3,000
Sale proceeds: £53,000

Journal entry:

Dr Cash 53,000
Cr Investment in corporate bonds 50,000
Cr Gain on disposal of investment 3,000

4) Convertible debt conversion (issuer-side)

Assume the carrying amount of the debt component converted is £50,000. On conversion, the liability is removed and equity increases. (If an equity component had already been recognised within equity at initial issue, that balance would be reclassified within equity as part of the conversion.)

Dr Convertible debt liability 50,000
Cr Equity (share capital and/or share premium) 50,000

5) Effect of market yield changes on bond prices (valuation logic)

Bond value is the present value of future cash flows discounted at the current market yield for instruments of similar risk and maturity.

• If market yield increases, bond price decreases.
• If market yield decreases, bond price increases.

Illustration using a £100 par bond, 5% annual coupon, 3 years remaining:

Bond price = 5/(1 + yield)^1 + 5/(1 + yield)^2 + 105/(1 + yield)^3

At 8%:

Bond price at 8% = 5/(1.08) + 5/(1.08^2) + 105/(1.08^3) = 92.27 (approx)

At 4%:

Bond price at 4% = 5/(1.04) + 5/(1.04^2) + 105/(1.04^3) = 102.78 (approx)

Interpretation of the results

ABC Ltd uses both short-term and long-term instruments:

• Deposit interest (£2,500) increases profit and equity.
• Interest paid (£1,000) reduces profit and equity.
• Bond issuance increases cash and long-term liabilities (net of issue fees).
• Sale of corporate bonds realises a gain (£3,000) and increases equity through profit.
• Share issue increases equity without a repayment obligation.
• Conversion of convertible debt reduces liabilities and increases equity.
• Dividends reduce equity directly (they are not an expense).
• Higher market yields reduce bond prices, which affects reported values where fair value measurement applies and affects decision-making even when fair value changes are not recognised.

Accounting equation effects (high-level):

• Bond issue: Assets ↑, Liabilities ↑
• Share issue: Assets ↑, Equity ↑
• Interest paid: Assets ↓, Equity ↓ (via profit)
• Dividends paid: Assets ↓, Equity ↓ (distribution)
• Conversion: Liabilities ↓, Equity ↑
• Sale at gain: Assets ↑, Equity ↑ (via profit)

Common pitfalls and misunderstandings

• Confusing money markets (short-term liquidity) with capital markets (long-term funding and investment).
• Treating dividends as an expense instead of a distribution to owners.
• Ignoring the difference between directly attributable transaction costs and general administration costs.
• Using an over-simplified bond pricing method that does not discount each cash flow separately.
• Assuming preference shares are always equity because of the name, rather than analysing whether cash payments or redemption are unavoidable.
• Recording conversion of convertible debt as a profit event rather than primarily a reclassification between liabilities and equity.
• Assuming a quoted instrument is always easy to sell quickly at a fair price (liquidity can disappear under stress).

Summary

Financial markets connect surplus cash to funding needs and support saving, borrowing, and investment decisions. Money markets focus on short-term liquidity management, while capital markets provide long-term funding and investment opportunities. Intermediaries improve access, reduce dealing costs, and offer liquidity and risk services, but they also introduce credit, liquidity, and systemic risks.

Financial instruments differ by purpose, return, risk, and liquidity. Debt funding creates liabilities and interest expense for issuers, while debt investments generate interest income and may generate gains or losses on sale or remeasurement. Equity funding strengthens the capital base without a repayment obligation, but returns are uncertain. Bond values move inversely with market yields because valuation depends on discounting future cash flows at current market rates.

FAQ

What is the primary difference between money markets and capital markets?

Money markets deal mainly with short-term borrowing and lending (typically up to one year) and are used for liquidity management. Capital markets deal mainly with long-term funding and investment through instruments such as bonds and shares.

How do financial intermediaries add value to financial markets?

They pool funds, reduce dealing costs, assess and monitor credit risk, provide liquidity, and improve market access. The trade-off is that they can concentrate risk and face liquidity pressure when many customers demand cash at the same time.

What are the key risks associated with financial instruments?

Common risks include credit risk (default), interest-rate risk (sensitivity to yield changes), liquidity risk (difficulty selling quickly at a fair price), and market risk (price volatility driven by broader economic factors).

How does classification affect the financial statements?

Classification influences measurement and where value changes are reported. Some instruments recognise returns mainly through interest over time, while others recognise fair value changes in profit or loss (or, for certain instruments, outside profit or loss).

What is the impact of market yield changes on bond prices?

Bond prices move inversely with yields because the price is the present value of future cash flows discounted at the current market yield for similar risk and maturity.

Why is liquidity important in financial markets?

Liquidity allows assets to be converted into cash quickly at a reasonable price, helping entities meet obligations and manage short-term cash flow without distress sales.

What are the benefits and risks of convertible debt?

Convertible debt can reduce cash interest costs and may be attractive to investors seeking upside through conversion. Risks include complexity, potential dilution for existing shareholders, and continued credit and interest-rate risk until conversion occurs.

A bank-issued time deposit with a fixed term and stated return; some CDs are tradable, improving flexibility for investors.

Bond
A debt instrument where the issuer promises periodic interest payments and repayment of principal at maturity. For the issuer it is a financial liability; for the holder it is a financial asset.

Government security
Debt issued by a government. Often viewed as lower credit risk than corporate debt, but still exposed to interest-rate risk and market price movements when traded.
