How To Calculate Treasury Bills In Nigeria

Treasury bills (T-bills) are short-term government securities issued by the Central Bank of Nigeria (CBN) on behalf of the Nigerian government. They are one of the most popular investment options in the country because they offer a safe and low-risk way to earn returns. Treasury bills are used by investors, including individuals, businesses, and even foreign investors, to park their funds for short periods while earning interest. In this blog post, we will take a deep dive into the world of T-bills in Nigeria, how to calculate their returns, and why they are an excellent option for people looking to invest their money wisely.

What Are Treasury Bills (T-Bills)?

Treasury bills are short-term debt instruments issued by the Nigerian government to raise money for its daily operations and to manage liquidity. These instruments are sold at a discount to their face value and pay a fixed return to the investor when they mature. T-bills usually have maturities of 91 days, 182 days, or 364 days, meaning they are short-term in nature.

For example, if you purchase a treasury bill with a face value of ₦100,000 for ₦95,000, at the end of the term (whether 91, 182, or 364 days), you will receive the full ₦100,000, meaning the difference between the price you paid and the face value is your return.

Why Do People Invest in Treasury Bills?

Before diving into the technical side of calculating T-bills, let’s briefly understand why they are so popular in Nigeria. Treasury bills offer several benefits, making them a go-to choice for conservative investors:

1. Low Risk: Since T-bills are issued by the government, they are considered one of the safest investments in the country. There’s a very low chance that the Nigerian government will fail to repay its debt, making T-bills a secure investment choice.

2. Fixed Returns: The interest on T-bills is fixed, which means you will know exactly how much you will earn when the bill matures. This can help you plan your finances effectively.

3. Liquidity: T-bills are highly liquid, meaning you can easily sell them in the secondary market before they mature if you need quick access to your funds.

4. Low Minimum Investment: Unlike other investments that may require a significant amount of money to start, T-bills can be bought for as little as ₦1,000, making them accessible to many people.

Now that we know a little bit about T-bills, let’s dive into how to calculate the returns from these government securities.

How Do Treasury Bills Work?

When you invest in a treasury bill, you are essentially lending money to the government. In return for your investment, the government promises to pay you back the full face value of the T-bill at maturity. However, you do not earn interest in the traditional sense; instead, you buy the T-bill at a discount and then receive the full face value when it matures.

For example:

If you buy a T-bill with a face value of ₦100,000 at ₦95,000, the difference between the price you paid (₦95,000) and the face value (₦100,000) is your profit, which is ₦5,000. This profit is often referred to as the interest or yield of the T-bill.

Steps to Calculate the Return on Treasury Bills

To calculate the return on your treasury bill, you need to know:

• The face value of the bill (the amount you’ll be paid when the bill matures).

• The purchase price of the bill (the amount you pay when you buy the bill).

• The term or maturity period of the bill (91, 182, or 364 days).

Formula for Calculating T-bill Yield

The general formula for calculating the yield or return on a treasury bill is:

T-bill Yield = (Discount / Purchase Price) x (365 / Days to Maturity) x 100

Where:

• Discount is the difference between the face value and the purchase price of the T-bill.

• Purchase Price is the amount you paid for the T-bill.

• Days to Maturity is the number of days left until the T-bill matures.

Example 1: Calculating Yield for a 91-day T-Bill

Let’s say you purchase a 91-day treasury bill with the following details:

• Face Value: ₦100,000

• Purchase Price: ₦96,000

• Maturity: 91 days

Step 1: Find the discount. The discount is the difference between the face value and the purchase price. So, the discount = ₦100,000 - ₦96,000 = ₦4,000.

Step 2: Apply the formula for yield. T-bill Yield = (₦4,000 / ₦96,000) x (365 / 91) x 100 T-bill Yield = 0.04167 x 4.01 x 100 T-bill Yield = 16.7%

So, the yield on this T-bill investment is 16.7%. This means that you would earn a return of 16.7% on your investment if you held the T-bill until it matured.

Example 2: Calculating Yield for a 182-day T-Bill

Now let’s look at a 182-day T-bill with the following details:

• Face Value: ₦100,000

• Purchase Price: ₦92,000

• Maturity: 182 days

Step 1: Find the discount. Discount = ₦100,000 - ₦92,000 = ₦8,000.

Step 2: Apply the formula for yield. T-bill Yield = (₦8,000 / ₦92,000) x (365 / 182) x 100 T-bill Yield = 0.08696 x 2.00 x 100 T-bill Yield = 17.4%

So, for this 182-day T-bill, the yield would be 17.4%. This means that for every ₦100,000 you invested, you would earn ₦17,400 at the end of 182 days.

Factors That Influence T-Bill Yields

The yield on treasury bills can fluctuate depending on several factors:

1. Interest Rates: The Central Bank of Nigeria (CBN) sets interest rates that influence the returns on T-bills. If interest rates rise, the yields on newly issued T-bills will increase as well.

2. Inflation: High inflation can reduce the real return on T-bills because inflation erodes the purchasing power of the money you receive when the T-bill matures. However, T-bills can still offer protection against inflation compared to keeping cash in a savings account.

3. Market Demand and Supply: If more people want to buy T-bills, the price of the T-bills might go up, which could lower the yield. On the other hand, if fewer people are buying, the price might decrease, leading to higher yields.

4. Government Fiscal Policy: The government’s need for funds can also influence T-bill yields. If the government needs more funds, it may offer higher yields to attract more investors.

How to Buy Treasury Bills in Nigeria

Buying treasury bills in Nigeria is a straightforward process, but you must have a Nigerian bank account and a Securities Trading Account. Here's a step-by-step guide on how to buy T-bills:

1. Open a Securities Trading Account: You need to have a Securities Trading Account with a licensed stockbroker or financial institution. This is where your T-bills will be held.

2. Visit the CBN or Authorized Bank: You can buy T-bills directly from the Central Bank of Nigeria through its primary market auctions. Alternatively, you can buy T-bills through your bank or other licensed financial institutions that offer the service.

3. Participate in the Auction: Treasury bills are sold at periodic auctions held by the Central Bank. The bids are either competitive or non-competitive. In a competitive bid, you specify the yield you are willing to accept. In a non-competitive bid, you agree to accept the yield determined by the auction.

4. Wait for Maturity: After purchasing the T-bill, you wait until it matures. At maturity, the government pays you the face value of the bill, which includes your initial investment plus the discount you earned.

Conclusion

Treasury bills are a great way to make your money work for you while keeping it safe. With their low-risk nature, fixed returns, and short-term commitment, T-bills provide a perfect investment for anyone looking to earn interest without worrying about market volatility.
