A Treasury Bill (T-Bill) is a short-term government security with a maturity period of one year or less. T-Bills are issued by a government and are sold in the primary market at a discount to their face (par) value. Upon maturity, the government pays the holder the full face value, and the difference between the purchase price and the face value represents the interest earned by the investor.

Historical Context
The U.S. Treasury first issued T-Bills in 1929, designed to provide a flexible means of raising short-term capital. Over the decades, T-Bills have become one of the most popular and trusted financial instruments for both individual and institutional investors due to their:
- Low-risk Nature: Backed by the full faith and credit of the issuing government.

Significance in Financial Markets
T-Bills are a cornerstone of short-term debt markets and play several critical roles:

Examples
Example 1: Purchasing a T-Bill
Consider a 26-Week T-Bill with a face value of $100,000, purchased at $98,000:
- Discount Rate:
$$ \left( \frac{100,000 - 98,000}{100,000} \right) \times \left( \frac{360}{182} \right) = 0.03956 \text{ or 3.956\%} $$
- Investment Yield:
$$ \left( \frac{100,000 - 98,000}{98,000} \right) \times \left( \frac{365}{182} \right) = 0.04067 \text{ or 4.067\%} $$
