The Difference Between Debt & Equity
-
Debt is a liability; it represents what firms owe
-
Individuals or businesses that lend money to a firm are called creditors
-
E.g. Banks loans, corporate bonds, and mortgages
-
-
Equity represents all physical and financial assets owned by firm
-
Firms can raise finance by issuing shares or corporate bonds
-
-
Firms can use both debt and equity as a source of finance for their operations

The Relationship Between Interest Rates & Bond Prices
Key terminology in the bond market
-
Market interest rates (also known as yields) are the cost of borrowing money or the return on savings
-
Bond prices are the amount investors are willing to pay for government bonds
-
Governments and big companies issue bonds to raise funds for various purposes, like covering a government’s budget deficit or allowing a company to invest in new equipment
-

Interest rates, bond prices and secondary markets
-
Before a bond reaches maturity, it can be resold in secondary markets
-
Investors can buy or sell them at prices different from the nominal value
-
E.g. Market price is £1,100 compared to nominal value of £1,000
-
-
Market prices for bonds vary in the secondary market due to market forces
-
If the interest on bonds is high relative to other returns on investment, demand for bonds increases
-
The lower the demand for bonds, the lower the market price
-
-
Diagram: The Relationship Between Interest Rates and Bond Prices

-
Market forces cause interest rates to vary
-
If government issues a bond this year with 5% interest, they may have to issue bonds with 7% interest next year due to market forces
-
The interest rate on each bond is fixed
-
-
5% bonds now have a less attractive return on investment in the secondary market
-
E.g, They have a 2% lower return compared to new bonds issued
-
Existing bonds will be less attractive to investors
-
As a result, demand falls for existing bonds, causing price of bonds to fall
-
-
The opposite will also be true. If the government issues new bonds at a lower interest rate, then the demand for existing bonds will increase
-
If government issued a bond last year at 5%, they may have to issue bonds at 3% this year
-
Existing bonds will be more attractive to investors than the new bonds
-
As a result, demand for existing bonds rises, causing the price to rise
-
The new bond price may fall relatively quickly in the secondary market
-
-
Therefore, long-run rate of interest and yields have an inverse relationship with government bonds prices
-
As interest rates rise, bond prices fall
-
As interest rates fall, bond prices rise
-
Worked Example
Calculating a yield on a government bond
Let’s consider a government issuing a new 50-year gilt with a nominal value of £100, an annual coupon payment of £5, and a current market price of £75. Calculate the yield on the gilt at this point.
Step 1: Identify the variables
-
Nominal value (face value) of the gilt: £100
-
Annual coupon payment: £5
-
Current market price: £75
Step 2: Apply the formula
