What Are Treasury Bills?

Treasury bills, or T-bills, are short-term loans issued by the Central Bank of Nigeria on behalf of the Federal Government. They serve as government IOUs. When you purchase a treasury bill, you are lending money to the government for a particular time period.
In exchange, the government pays you interest. Unlike a bank deposit, you lend directly to the government. T-bills are appealing because they are backed by the full faith and credit of the Federal Government of Nigeria, lowering the risk of losing your principal.

Benefits of Treasury Bills
- Low minimum investments (through platforms): With modern financial technology and investing platforms, it is no longer necessary to invest substantial sums of money in T-bills. Your money is locked in. Once you invest in a T-bill, you cannot access your funds until they mature. While a secondary market exists to sell T-bills early, it is not necessarily efficient or clear.
- Returns: If inflation surpasses your T-bill rate, your real returns may be negative since your money’s purchasing power decreases.
- Opportunity Cost: Money invested in T-bills cannot be used for another purpose. For example, if you buy a 364-day T-bill at 12% and stocks yield 30%, you will miss out on the higher return.
- Tax: Interest on treasury bills is subject to withholding tax, which affects your net earnings.
Factors that Affect Treasury Bill Prices
1. Maturity
A T-bill’s price is strongly influenced by its maturity time. A one-year bill yields more profit than a three-month bill. As a result, investors receive a higher rate of return to compensate for locking up their money for a longer period.
2. Risk
The price of a T-bill is also influenced by investors’ risk appetites. T-bills are less desirable and will be priced lower as the economy grows, while other debt products offer larger returns.
When the markets and the economy are volatile, and other debt assets are seen as riskier, T-bills command a higher price due to their lower risk.
3. Inflation
The current rate of inflation may also affect the cost of T-bills. For example, if the inflation rate was 5% and the T-bill discount rate was 3%, investing in T-bills would be unprofitable since the real rate of return would be negative. As a result, there will be less demand for T-bills, resulting in reduced prices.
Conclusion
Treasury bills in Nigeria are a safe way to grow your money. They offer guaranteed returns, are backed by the government, and are widely available through commercial banks. Whether you use GTBank, Zenith Bank, or Access Bank, the process is straightforward.
For small investors, the secondary market through banks is the easiest entry point. For larger institutions, bidding directly at CBN auctions provides more flexibility.
If you want a low-risk investment in Nigeria that beats savings accounts, treasury bills are one of the best options.
