Did you know that the US government sells short-term debt to fund its activities? This is done through instruments called Treasury bills, often shortened to T-bills. They are considered a very safe haven for your money.
The US Department of the Treasury issues the short-term government securities to pay for government operations. They are a popular option for those seeking low-risk, quick turnaround returns on investment. T-bills usually have terms ranging from a few weeks up to one year.
How Treasury Bills Work
When you purchase a T-bill, think of it as lending funds to the government for a specific timeframe. You pay less than what the T-bill is worth, its face value.
When the T-bill matures, you receive the full face value.
The difference you paid initially and the face value is the interest.
Calculating the Price of a Treasury Bill
A method, called the bank discount basis yield, estimates the price of a T-bill. Keep in mind that the bank discount yield differs from the actual yield. The formula for determining the price of a T-bill using the bank discount yield is shown below:
Price = Face Value * (1 - (Discount Rate * Time) / 360)
Where:
The discount rate is the bank discount yield.
Time is the number of days until the T-bill matures.
Example Calculation
Let's determine the price of a T-bill with a face value of $100,000, using a bank discount yield of 5% for a term of one year.
Face Value - $100,000
Discount Rate - 5% or 0.05
Time - 365 days (one year)
Using the formula:
Price = 100,000 * (1 - (0.05 * 365) / 360)
Price = 100,000 * (1 - (18.25 / 360))
Price = 100,000 * (1 - 0.0506944)
Price = 100,000 * 0.9493056
Price = 94,930.56
Based on the calculations, the price of the T-bill is approximately $94,930.56.
Understanding the Bank Discount Basis
The bank discount basis is a calculation for the return on investments like T-bills. It is determined as:
Bank Discount Yield = (Discount / Face Value) * (360 / Time to Maturity)
Where:
Discount is the difference in the face value and the initial price.
Time to Maturity is how many days remain before the T-bill matures.
This method simplifies the math with a 360-day year, hence the name "bank discount basis."
True Yield vs. Bank Discount Yield
While the bank discount yield gives an easy route to determine the return on a T-bill, it isn't necessarily the actual or effective yield.
The actual yield accounts for the term remaining, as well as the compounding impact of interest, giving a more reliable picture of the return.
