Money market instruments are short-term debt securities with one year or less of original maturities. They play a crucial role in the financial market and encompass various instruments like overnight sale and repurchase agreements (repos), bank certificates of deposit, commercial paper, Treasury bills, bankers’ acceptances, and time deposits tied to market reference rates. For example, a company might issue commercial paper to address its short-term liquidity requirements. Money market mutual funds, exclusively investing in eligible money market securities, are occasionally viewed as alternatives to bank deposits.
Yield measures for money market instruments differ from those for bonds in several ways. Firstly, bond yields-to-maturity are annualized and compounded, while yield measures in the money market are annualized but not compounded. This means the return on a money market instrument is stated on a simple interest basis. For example, if you invest $1000 in a 90-day Treasury bill with a yield of 1%, you would earn $10 at the end of the period.
Secondly, bond yields-to-maturity are generally presented uniformly for all times-to-maturity. In contrast, money market instruments, with their diverse times-to-maturity, exhibit different periodicities for the annual rate. Lastly, the calculation of bond yields-to-maturity employs standard time-value-of-money analysis. On the other hand, money market instruments are often quoted using non-standard interest rates, requiring distinct pricing equations compared to those utilized for bonds.
Quoted money market rates can be either discount rates or add-on rates. Commercial paper, Treasury bills, and bankers’ acceptances are commonly quoted on a discount rate basis. In contrast, bank certificates of deposit, repos, and market reference rate indexes are quoted on an add-on rate basis. In the money market, a discount rate pertains to an instrument where interest is already included in the face value. In contrast, an add-on rate involves interest added to the principal or investment amount.
The pricing formula for money market instruments quoted on a discount rate basis is:
\[PV = FV \times \left( 1 – \frac{\text{Days}}{\text{Year}} \times DR \right)\]
Where:
PV = Present value, or the price of the money market instrument.
FV = The future value paid at maturity or the face value of the money market instrument.
Days \(=\) The number of days between settlement and maturity.
Year \(=\) The number of days in the year.
\(\mathbf{DR} =\) The discount rate, stated as an annual percentage rate.
\[DR = \frac{\text{Year}}{\text{Days}} \times \frac{(FV – PV)}{FV}\]
The pricing formula for money market instruments quoted on an add-on rate basis is:
\[PV = \frac{FV}{1 + \frac{\text{Days}}{\text{Year}} \times AOR}\]
Where:
PV = Present value, the principal amount, or the price of the money market instrument.
\(\mathbf{FV} =\) The future value, or the redemption amount paid at maturity, including interest.
Days \(=\) The number of days between settlement and maturity.
Year \(=\) The number of days in the year.
\(\mathbf{AOR} =\) The add-on rate, stated as an annual percentage rate.
\[AOR = \frac{\text{Year}}{\text{Days}} \times \frac{FV – PV}{PV}\]
Investment analysis is more challenging for money market securities because some instruments are quoted on a discount rate basis while others are on an add-on rate basis, and some assume a 360-day year, and others use a 365-day year. Furthermore, the “amount” of a money market instrument quoted by traders on a discount rate basis is typically the face value paid at maturity. On the other hand, the “amount,” when quoted on an add-on rate basis, usually is the price at issuance.
The bond equivalent yield, often termed the investment yield, quantifies a money market rate using a 365-day add-on rate method.
Step 1:
For money market assets priced with a Discount Rate (DR), compute the Price for every 100 of Par (PV) as:
\[PV = FV \times \left( 1 – \frac{\text{Days}}{\text{Year}} \times DR \right)\]
Step 2:
From the PV obtained in Step 1, determine the Add-on Rate (AOR) for that specific money market asset:
\[AOR = \frac{\text{Year}}{\text{Days}} \times \left( \frac{FV – PV}{PV} \right)\]
Step 3:
The Bond Equivalent Yield (BEY) represents a money market rate defined using a 365-day AOR method.
With this, the asset can be evaluated alongside other money market assets that use the Bond Equivalent Yield as their standard.
Suppose an investor is comparing the following two money market instruments:
Which one offers the higher expected rate of return, assuming the same credit risk?
Solution
60-day Treasury bill:
Using the formula:
\[PV = FV \times \left( 1 – \frac{\text{Days}}{\text{Year}} \times DR \right)\]
\[PV = 100 \times \left( 1 – \frac{\text{60}}{\text{360}} \times 0.0005 \right) = 99.99 \]
\[AOR = \frac{\text{Year}}{\text{Days}} \times \left( \frac{FV – PV}{PV} \right)\]
\[ AOR = \frac{365}{60} \times \left( \frac{100 – 99.99}{99.99} \right) = 0.0608\% \]
The bond equivalent rate is, therefore, 0.0608%
The bond equivalent rate for the 60-day bank certificate of deposit is \(0.060\%\) or 0.0006.
The 60-day Treasury bill offers a higher annual return relative to the 60-day bank certificate of deposit.
Question
The bond equivalent yield of a 180-day Treasury bill quoted at a discount rate of 0.75% for a 360-day year is closest to:
- 0.750%.
- 0.753%.
- 0.763%.
Solution
The correct answer is C.
Step 1:
For money market assets priced with a Discount Rate (DR), compute the Price for every 100 of Par (PV) as:
\[PV = FV \times \left( 1 – \frac{\text{Days}}{\text{Year}} \times DR \right)\]
\[PV = 100 \times \left( 1 – \frac{\text{}\text{180}}{\text{}\text{360}} \times 0.75\% \right) = \ 99.6250\ \]
Step 2:
From the PV obtained in Step 1, determine the Add-on Rate (AOR) for that specific money market asset:
\[AOR = \frac{\text{Year}}{\text{Days}} \times \left( \frac{FV – PV}{PV} \right)\]
\[AOR = \frac{\text{}\text{365}}{\text{}\text{180}\text{}} \times \left( \frac{100 – 99.6250}{99.6250} \right) = 0.763\%\]
