Fixed Income Essentials U. This is known as inflation risk. The short maturity of Treasury bills, however — one, three, six or even 12 months — minimises the likely difference between actual and expected inflation and hence their inflation risk is almost nil.
Treasury bills in most countries are traded in large nominal amounts. The return offered on Treasury bills can be considered to be almost a risk-free rate and the minimum required rate of return for all investors. All other securities are considered to be riskier than Treasury bills, in the sense that they are more volatile in their price movements i.
These securities should offer investors an expected rate of return at least as high as the return offered on Treasury bills. An alternative estimate of the risk-free rate of return is obtainable on long-term government bonds.
This definition is often preferred by managers when determining a benchmark risk-free rate because, they argue, they are typically looking at long-term projects and their investors are looking to invest over the long term. Figure 4 explains how to understand UK government bond terminology, such as the interest paid on the bond known as the coupon , its title and its maturity or redemption date.
UK government bonds are called gilts — the certificates used to be gilt-edged and as the UK government has never defaulted on a debt, they can be considered as secure as gold! Treasury bills and long-term government bonds can be considered essentially risk free. Note, however, that the return expected from a Treasury bill is likely to differ from the return expected on, say, a year government bond, since investors require different returns on investments with different maturities.
These different returns are often described as the term structure of interest rates and can be shown graphically in what is called a yield curve , where the yield on the y-axis or vertical is plotted against maturity on the x-axis or horizontal.
Remember that all yields or interest rates are given on an annualised basis for ease of comparison.
In the text, p. Figure 5 shows the yield curve for UK government bonds, or gilts starting at three months and stretching out to 30 years at a particular point in time in this case, 16 December So, on that day, investors required only just over 20 basis points or just over 0.
In contrast, investors required 2. This means that, the longer the maturity of the bond i. This is called a rising yield curve. Figure 6 shows the alternative yield curves. The simplest way to explain why there are different shapes of yield curve is to do with expectations, the so-called expectations hypothesis.
For example, if investors expect rates to go up in the future, the yield curve will be rising; if investors think they will go down, the yield curve will slope downwards.
Flat yield curves are due to an expectation that interest rates will remain unchanged. However, supply and demand also influence yield curves. For small business. For enterprise. Even the safest investments have an element of risk. Because of this, investors will often demand a rate of return that reflects inflationary expectations. Find out everything you need to know about the risk-free interest rate, including how to calculate it and what it means for businesses and investors. First off, what is a risk-free interest rate?
The risk-free interest rate, also referred to as the risk-free rate of return, is a theoretical interest rate of an investment which carries zero risk. Technically, the risk-free interest rate is purely theoretical, as all investments have some type of risk attached to them. Having said that, although it is possible for the government to default on its securities, the likelihood of this happening is enormously low.
Essentially, the real risk-free interest rate refers to the rate of return required by investors on zero-risk financial instruments without inflation. By contrast, the nominal risk-free interest rate is the observed return on a risk-free asset. Risk Management. Portfolio Management. Your Privacy Rights.

Bonds Fixed Income Essentials. Key Takeaways The risk-free rate of return refers to the theoretical rate of return of an investment with zero risk. In practice, the risk-free rate of return does not truly exist, as every investment carries at least a small amount of risk.
To calculate the real risk-free rate, subtract the inflation rate from the yield of the Treasury bond matching your investment duration. Why Is the U. What Are the Common Sources of Risk?
