Chapter 17: Financial Markets
Financial markets connect firms that need capital to grow with households and investors who have savings to invest. This chapter explores how businesses raise money (profits, loans, bonds, stock), how households choose among savings vehicles (bank accounts, bonds, stocks, mutual funds, housing), and the return–risk–liquidity tradeoffs that shape every investment decision.
Table of Contents
1. How Businesses Raise Financial Capital
1.1 Profits as a Source of Financial Capital
For established companies, reinvesting profits is a primary source of financial capital. However:
- Startups have many investment opportunities but few profits
- Even large firms may experience years of low profits or losses
- Firms need external financial capital sources to survive tough times
1.2 Borrowing: Banks and Bonds
Bank loan: A customized agreement where a firm borrows money and promises to repay with interest over a set period. Better for relatively small firms because the bank monitors the firm closely (deposits, withdrawals, revenue patterns).
Bond: A financial contract where a borrower agrees to repay the principal plus interest over a set period. Better for larger, well-known firms.
Types of bonds:
| Type | Issuer |
|---|---|
| Corporate bond | Firms / corporations |
| Municipal bond | Cities |
| State bond | U.S. states |
| Treasury bond | Federal government (U.S. Department of the Treasury) |
Bond example: A large company issues bonds for $10 million at an annual interest rate of 8%, paying $800,000 per year in interest for 10 years, then repaying the $10 million principal. The company might issue 10,000 bonds of $5,000 each, allowing individual investors to participate.
Key differences:
| Feature | Bank Loan | Bond |
|---|---|---|
| Customization | Highly customized | Standardized |
| Best for | Smaller firms | Larger, well-known firms |
| Relationship | Bank monitors firm closely | Bondholders are more arms-length |
| If firm defaults | Bank can take firm to court | Bondholders can require bankruptcy |
1.3 Corporate Stock and Public Firms
Stock: Represents firm ownership. A person who owns 100% of a company’s stock owns the entire company. Stock is divided into shares.
Corporation: A business owned by shareholders who have limited liability for the company’s debt but share in its profits (and losses).
Three key questions about stock:
1. When does the company receive money?
- Only at the Initial Public Offering (IPO) — the first sale of stock to the public — and in secondary offerings
- When existing shareholders buy/sell stock among themselves, the firm receives nothing
- IPOs repay early-stage investors (angel investors, venture capital firms) and provide expansion capital
2. What return does stock offer?
- Dividends: Direct cash payments from the firm to shareholders
- Capital gains: Profit from selling stock at a higher price than the purchase price
3. Who makes decisions?
- Private company: Owned and run by the people who manage it daily
- Sole proprietorship: One individual
- Partnership: A group of individuals
- Large private corporations also exist (Cargill, Mars, Bechtel)
- Public company: Stock is traded publicly; shareholders vote for a board of directors, which hires top executives
Corporate governance problem: Top executives often have a strong voice in choosing board candidates. Few shareholders have enough knowledge or incentive to nominate alternative board members. This led to failures like Lehman Brothers (2008) — the 4th largest U.S. investment bank (25,000 employees, 164 years old) filed for bankruptcy due to excessive risk-taking with insufficient board oversight.
1.4 How Firms Choose Between Capital Sources
| Stage | Typical Source | Why |
|---|---|---|
| Startup | Personal savings, angel investors, venture capital | Imperfect information is highest — investors need personal knowledge of founders |
| Established, growing | Bank loans, bonds | Track record reduces information asymmetry |
| Large, well-known | Bonds, stock (IPO or secondary offering) | Broad public information available; can access large capital pools |
Borrowing (bonds/loans):
- Advantage: Firm maintains full control; no shareholders to answer to
- Disadvantage: Committed to scheduled interest payments regardless of income
Issuing stock:
- Advantage: No repayment obligation; access to large amounts of capital
- Disadvantage: Dilutes ownership; firm answers to board and shareholders; expensive process; SEC reporting requirements
2. How Households Supply Financial Capital
Every investment can be evaluated on three dimensions:
- Expected rate of return: How much the investment is expected to earn (interest, dividends, capital gains)
- Risk: The uncertainty of actual returns — high risk means a wide range of possible outcomes
- Liquidity: How easily the investment can be converted to spendable cash
2.1 Bank Accounts
Financial intermediary: An institution (like a bank) that operates between savers who deposit funds and borrowers who receive loans. Savers and borrowers never meet directly.
| Account Type | Interest | Access | Notes |
|---|---|---|---|
| Checking account | Little or none | Very easy (checks, debit card) | Highest liquidity |
| Savings account | Some interest | Moderate (trip to bank/ATM, electronic transfer) | Slightly less liquid |
| Certificate of Deposit (CD) | Higher interest | Locked for set period (months to years) | “Substantial penalty for early withdrawal” |
Safety: FDIC insures deposits up to $250,000 per depositor per bank (raised from $100K in 2008).
Bottom line: Low risk → low return → high liquidity.
2.2 Bonds (Investor Perspective)
Interest rate components:
- Compensation for delaying consumption
- Adjustment for expected inflation
- Risk premium for borrower’s riskiness
Bond terminology:
| Term | Meaning |
|---|---|
| Face value | Amount the borrower will repay at maturity |
| Coupon rate | Annual interest rate printed on the bond |
| Maturity date | When the borrower repays the face value |
| Bond yield | The total effective rate of return at time of purchase |
| Present value | Most a buyer would pay for the bond given current market rates |
High-yield bonds (junk bonds): Bonds that offer high interest rates to compensate for a relatively high chance of default. Turner Broadcasting and Microsoft both issued junk bonds in the 1980s when they were starting to grow.
Bond yield calculation:
You bought a $1,000 bond at 8% coupon rate (pays $80/year). Market rates rise to 12%. One year remains until maturity.
- Expected payment in 1 year: $1,000 (face value) + $80 (final interest) = $1,080
- Alternative investment at 12%: You’d need $964 today → $964 × 1.12 = $1,080
- Therefore, the bond is now worth only $964 (not the $1,000 face value)
- Yield: ($1,080 − $964) / $964 = 12%
Rule: When market interest rates rise, existing bonds lose value. When rates fall, existing bonds gain value.
Multi-Period Bond Valuation Formula
For a bond with $n$ years to maturity, coupon payment $C$, face value $F$, and market rate $r$:
\[PV = \sum_{t=1}^{n} \frac{C}{(1+r)^t} + \frac{F}{(1+r)^n}\]Example: A $1,000 bond with 5% coupon ($C = $50$), 3 years to maturity, market rate 8%:
\[PV = \frac{50}{1.08} + \frac{50}{1.08^2} + \frac{50}{1.08^3} + \frac{1000}{1.08^3}\] \[= 46.30 + 42.87 + 39.69 + 793.83 = \$922.69\]The bond trades at a discount ($922.69 < $1,000) because its 5% coupon is below the 8% market rate.
Bottom line: Low-to-moderate return and risk (depending on issuer); moderate liquidity.
2.3 Stocks
Stock returns come from dividends and capital gains — but the range is enormous:
- Netflix: $295/share (July 2011) → $53.91 (July 2012) → $199 (2022)
- Facebook: ~$40/share at IPO → $212 (2022)
Major stock market measures:
| Index | Description |
|---|---|
| Dow Jones Industrial Average (DJIA) | 30 large U.S. companies, started 1896 |
| S&P 500 | 500 largest U.S. firms, weighted by market capitalization |
| Wilshire 5000 | ~7,000 firms — essentially all publicly traded U.S. companies |
| NYSE | Oldest/largest U.S. exchange (since 1792), ~2,800 companies |
| NASDAQ | Electronic exchange (since 1971), ~3,600 companies, tech-focused |
| FTSE | 100 largest London Stock Exchange companies (“footsie”) |
| Nikkei | 225 largest Tokyo Stock Exchange stocks |
| DAX | 30 largest Frankfurt, Germany stocks |
Historical S&P 500 returns:
| Decade | Total Annual Return | Capital Gains | Dividends |
|---|---|---|---|
| 1950–1959 | 19.25% | 13.58% | 4.99% |
| 1960–1969 | 7.78% | 4.39% | 3.25% |
| 1970–1979 | 5.88% | 1.60% | 4.20% |
| 1980–1989 | 17.55% | 12.59% | 4.40% |
| 1990–1999 | 18.21% | 15.31% | 2.51% |
| 2000–2009 | −1.00% | −2.70% | 1.70% |
| 2010–2019 | 12.65% | 10.35% | 2.30% |
| 2020 | 18.40% | 16.26% | 2.14% |
| 2021 | 28.71% | 26.89% | 1.82% |
Key trend: Dividends fell from ~4–5% in the 1950s–1980s to ~1.5–2.5% since the 1990s. Capital gains became the dominant return component. The 2000s decade had a negative total return.
Bottom line: High return over extended periods, but high risk (especially short-term); high liquidity.
2.4 Mutual Funds
Mutual fund: A fund that buys a variety of stocks or bonds from different companies, allowing investors to diversify easily. In 2021, over 47% of U.S. households invested in mutual funds.
Index fund: A mutual fund that seeks to mirror the overall market’s performance rather than trying to pick winning stocks.
Diversification: “Don’t put all your eggs in one basket” — buying from a wide range of companies to reduce risk.
In 2008, average U.S. stock mutual funds declined 38%, devastating those near retirement who depended on these funds.
Bottom line: Medium-to-high return; medium-to-high risk (but lower than individual stocks); medium-to-high liquidity.
2.5 Housing and Other Tangible Assets
Equity: The monetary value a homeowner would have after selling the house and repaying any outstanding bank loans.
Home equity calculation:
- Buy house for $200,000, put 10% down ($20,000), borrow $180,000
- Over time, pay loan down to $100,000 remaining; house value rises to $250,000
- Equity = $250,000 − $100,000 = $150,000
- About two-thirds of U.S. households own their home
- Total U.S. home equity: $23.6 trillion (mid-2021)
- Median existing home price: $122,900 (1990) → $232,000 (2016) — average 3.1% per year
- Housing provides both financial returns (capital gains) and nonfinancial returns (shelter/consumption)
Other tangible assets: Gold, silver, commodities (sugar, cocoa, oil), collectibles (paintings, wine, baseball cards). Gold: ~$300–500/oz (1981–2005) → $1,100 (2010) → $1,900+ (2022).
Bottom line: Moderate return (plus nonfinancial benefits); moderate-to-high risk; low liquidity.
2.6 Summary: Return vs. Risk vs. Liquidity
| Investment | Return | Risk | Liquidity |
|---|---|---|---|
| Checking account | Very low | Very little | Very high |
| Savings account | Low | Very little | High |
| Certificate of deposit | Low to medium | Very little | Medium |
| Stocks | High | Medium to high | Medium |
| Bonds | Medium | Low to medium | Medium |
| Mutual funds | Medium to high | Medium to high | Medium to high |
| Housing | Medium | Medium | Low |
| Gold | Medium | High | Low |
| Collectibles | Low to medium | High | Low |
Key tradeoff: Higher average returns compensate for higher risk. If risky assets like stocks did not offer higher average returns, few investors would want them. Time horizon matters: young workers can tolerate stock market volatility over decades; retirees should prefer lower-risk investments.
3. How to Accumulate Personal Wealth
3.1 The Random Walk Theory
Random walk with a trend: Stock prices follow an unpredictable path day-to-day (equally likely to rise or fall on any given day), but trend upward over long periods. Because stock prices reflect expectations about future profits, only unexpected news moves prices — and by definition, no one can predict unexpected news.
Sobering fact: Over time, half to two-thirds of mutual funds that try to pick winners actually perform worse than the market average. Professional stock pickers cannot consistently beat the market — and the average newspaper-reading investor has even worse odds.
3.2 The Slow, Boring Way to Get Rich
Two key choices:
1. Complete additional education:
| Education Level | Median Annual Income (2020) |
|---|---|
| High school diploma | $40,612 |
| Associate degree (2-year) | $48,776 |
| Bachelor’s degree (4-year) | $67,860 |
2. Start saving early — compound interest is powerful:
Simple interest: Interest calculated only on the original principal.
\[\text{Simple Interest} = P \times r \times t\]Compound interest: Interest calculated on the principal plus previously accumulated interest.
\(\text{Future Value} = P \times (1 + r)^t\)
Simple vs. compound interest ($100 at 5% for 3 years):
| Simple | Compound | |
|---|---|---|
| Year 1 | $100 + $5 = $105 | $100 × 1.05 = $105.00 |
| Year 2 | $105 + $5 = $110 | $105 × 1.05 = $110.25 |
| Year 3 | $110 + $5 = $115 | $110.25 × 1.05 = $115.76 |
| Total interest | $15.00 | $15.76 |
Difference seems small — but with larger sums and longer time periods, compounding creates enormous differences.
Power of long-term compounding:
Save $3,000 at age 25, invest at 7% real return for 40 years:
\[\$3{,}000 \times (1.07)^{40} \approx \$45{,}000\]The original investment multiplies nearly fifteen-fold. Saving $3,000 every year (or more as income rises) would accumulate hundreds of thousands of dollars by retirement — putting you at or near the top 10% of American households.
3.3 The 2007–2009 Housing Bubble and Financial Crisis
| Event | Details |
|---|---|
| Buildup (2003–2005) | Housing prices rose >10%/year; low interest rates; “subprime” loans with low/no down payments; NINJA loans (No Income, No Job, nor Assets) |
| Securitization | Banks sold mortgages to financial companies who pooled them into mortgage-backed securities and resold to investors worldwide |
| Collapse (2007–2009) | Prices fell; borrowers owed more than homes were worth; defaults surged; mortgage-backed securities became worthless |
| Great Recession | Credit froze → businesses couldn’t invest → layoffs → income/demand fell → more layoffs; unemployment: 5% → 10.1% peak |
| Aftermath | Global spread (Iceland, Ireland, UK, Spain, Portugal, Greece); European debt crisis and austerity measures; questions about euro viability |
4. Key Takeaways
- Firms raise capital through profits, bank loans, bonds, and stock — each with different advantages and obligations
- The IPO is the only time a company receives money from stock sales; subsequent trading is between investors
- Household investments are evaluated on return, risk, and liquidity — higher returns require accepting more risk or less liquidity
- Banks are financial intermediaries between savers and borrowers, with deposits insured by FDIC up to $250,000
- Bond prices move inversely to interest rates — when market rates rise, existing bond values fall
- Stocks offer the highest long-term returns (~10–18% in good decades) but with significant short-term volatility
- Diversification through mutual funds reduces individual company risk; index funds match market performance
- The random walk theory shows that consistently beating the market is extremely difficult — even for professionals
- The two reliable paths to wealth: (1) invest in education and (2) start saving early to harness compound interest
5. Practice Questions
Q1. What is the difference between a bank loan and a bond? When would a firm prefer each?
Answer
Both are forms of borrowing that commit the firm to scheduled interest payments. A bank loan is more customized and works better for smaller firms — the bank monitors the firm closely. A bond is a standardized financial contract, better for larger, well-known firms that can access many investors. Banks typically lend smaller amounts while bonds can raise very large sums from thousands of investors.Q2. A company issues 10,000 bonds of $5,000 each at 6% annual interest for 15 years. What is the total annual interest payment?
Answer
Total borrowed: 10,000 × $5,000 = $50,000,000. Annual interest: $50,000,000 × 0.06 = $3,000,000.Q3. You buy a $1,000 bond at 6% coupon. One year later, market rates rise to 9%, and there is one year left to maturity. How much is the bond worth now?
Answer
In one year, you'll receive $1,000 (face value) + $60 (final interest) = $1,060. At 9% market rate, the present value is $1,060 / 1.09 = $972.48. The bond has lost value because market rates exceed its coupon rate.Q4. Explain the difference between a dividend and a capital gain.
Answer
A dividend is a direct cash payment from a company to its shareholders. A capital gain is the profit earned when an investor sells a stock (or other asset) for more than they paid. Both represent returns on stock ownership, but dividends come from firm profits while capital gains come from market price increases.Q5. Why does a company receive money from a stock sale only during an IPO (or secondary offering), not when existing shares trade?
Answer
In an IPO, the company itself sells new shares to investors and receives the proceeds. After that, shares trade between investors on the secondary market — like buying a house from a current owner rather than the builder. The company is not a party to these transactions and receives none of the money.Q6. You buy a house for $300,000, put 15% down, and borrow the rest. Over time, you pay off $50,000 of the loan, and the house value rises to $350,000. What is your equity?
Answer
Down payment: $300,000 × 0.15 = $45,000. Loan: $255,000. After paying off $50,000: remaining loan = $205,000. Equity = house value − loan = $350,000 − $205,000 = $145,000.Q7. Why do financial advisors recommend mutual funds for most individual investors?
Answer
Mutual funds provide diversification — spreading risk across many companies so that if one stock falls, others may rise, smoothing overall returns. They also reduce transaction costs and eliminate the need for individual stock-picking expertise. Index funds in particular match market performance, which most professional investors fail to beat consistently.Q8. According to the random walk theory, why can’t investors reliably “beat the market”?
Answer
Stock prices reflect current expectations about future profits. Price changes are driven by unexpected news, which by definition is unpredictable. On any given day, prices are equally likely to rise or fall. While stocks trend upward over time, the specific ups and downs cannot be predicted, so consistently choosing stocks that outperform the average is practically impossible — even for professionals.Q9. Calculate the compound interest on $1,000 at 5% annual rate for 3 years. Compare it to simple interest.
Answer
Simple interest: $1,000 × 0.05 × 3 = $150. Total = $1,150. Compound interest: $1,000 × (1.05)³ = $1,000 × 1.157625 = $1,157.63. Interest earned = $157.63. Compound interest earns $7.63 more than simple interest over 3 years. The gap grows dramatically over longer periods and with larger sums.Q10. Rank these investments from lowest to highest expected return, and explain the risk tradeoff: (a) savings account, (b) Treasury bond, (c) corporate junk bond, (d) stock index fund.
Answer
Lowest to highest return: (a) savings account → (b) Treasury bond → (c) corporate junk bond ≈ (d) stock index fund. Risk increases in roughly the same order. Savings accounts are FDIC-insured with virtually no risk. Treasury bonds are very safe (U.S. government backing). Junk bonds offer high returns because of high default risk. Stock index funds offer high long-term returns with significant short-term volatility. Higher expected returns compensate for higher risk.Q11. What role did securitization of mortgages play in the 2007–2009 financial crisis?
Answer
Banks sold individual mortgages to financial companies who pooled them into mortgage-backed securities (MBS) and resold them to global investors. This transferred risk from banks to investors worldwide, but also reduced banks' incentive to carefully screen borrowers (since they wouldn't hold the loans). When housing prices fell, borrowers defaulted, MBS became worthless, and the losses spread globally, freezing credit markets and triggering the Great Recession.Q12. If you save $3,000 per year starting at age 25 earning 7% annually, approximately how much will you have at age 65?
Answer
This is an annuity problem. Using the future value of an annuity formula: $FV = PMT \times \frac{(1+r)^n - 1}{r}$ $FV = 3{,}000 \times \frac{(1.07)^{40} - 1}{0.07} = 3{,}000 \times \frac{14.974 - 1}{0.07} = 3{,}000 \times 199.64 \approx \$598{,}900$ Saving $3,000 annually at 7% for 40 years yields nearly $600,000 — approaching the top 10% of American household wealth, simply through consistent saving and compound interest.Q13. A $1,000 bond has a 4% coupon and 5 years to maturity. If the market interest rate is 6%, calculate the bond’s present value. Is it trading at a premium or discount?
Answer
$PV = \frac{40}{1.06} + \frac{40}{1.06^2} + \frac{40}{1.06^3} + \frac{40}{1.06^4} + \frac{40}{1.06^5} + \frac{1000}{1.06^5}$ $= 37.74 + 35.60 + 33.58 + 31.68 + 29.89 + 747.26 = \$915.75$ The bond trades at a **discount** ($915.75 < $1,000) because its coupon rate (4%) is below the market rate (6%). Investors demand a lower price to achieve a 6% effective yield.Q14. Two investors each invest $10,000 at 8% annual return. Investor A starts at age 25 and stops adding money. Investor B waits until age 35 to start. How much does each have at age 65?
Answer
**Investor A** (40 years of compounding): $FV = \$10{,}000 \times (1.08)^{40} = \$10{,}000 \times 21.72 = \$217{,}200$. **Investor B** (30 years of compounding): $FV = \$10{,}000 \times (1.08)^{30} = \$10{,}000 \times 10.06 = \$100{,}600$. Investor A has **$116,600 more** (over 2× as much) despite investing the same amount. Those extra 10 years of compounding more than doubled the final value. This illustrates the dramatic importance of starting early.Q15. During the 2008 crisis, average stock mutual funds declined 38%. A retiree had $500,000 in a stock index fund. (a) What was the portfolio value after the crash? (b) If the market then returns 10% annually, how many years to recover to $500,000? (c) What lesson does this illustrate about asset allocation?
Answer
**(a)** $500,000 \times (1 - 0.38) = \$310,000$. **(b)** Need $(1.10)^n \times 310{,}000 = 500{,}000 \implies (1.10)^n = 1.613 \implies n = \frac{\ln(1.613)}{\ln(1.10)} \approx \frac{0.478}{0.0953} \approx 5.0$ years. **(c)** Retirees who need their money soon should not have most of their portfolio in stocks. The **time horizon** matters: a 25-year-old can ride out a 5-year recovery, but a 65-year-old needing income cannot wait. This is why financial advisors recommend shifting from stocks to bonds/CDs as retirement approaches.6. Glossary
