What Is a Treasury Bill (Bono)? Understanding Short-Term Debt Securities
What Is a Treasury Bill (Bono)?
A Treasury Bill, commonly referred to as a Bono in many financial systems, is a short-term debt instrument issued by governments to finance short-term funding needs.
Unlike traditional bonds, treasury bills:
- Do not pay periodic interest
- Are issued at a discount to their face value
- Generate returns through the difference between purchase price and face value
Treasury bills are widely regarded as low-risk and highly liquid instruments, making them a core component of money markets.
Key Characteristics of Treasury Bills (Bonos)
Treasury bills have several defining features that distinguish them from other debt instruments.
1. Short-Term Maturity
Treasury bills typically have maturities of:
- 1 month
- 3 months
- 6 months
- 12 months
They are designed for short-term financing and cash management.
2. Zero-Coupon Structure
Treasury bills do not pay interest (coupons). Instead:
- They are sold at a discount
- Investors receive the full face value at maturity
3. Government Issuance
Treasury bills are issued by:
- National treasuries
- Central governments
This backing makes them among the safest financial instruments available.
4. High Liquidity
Treasury bills can be:
- Easily bought and sold
- Traded actively in secondary markets
- Used as collateral in financial transactions
5. Low Risk
Because they are government-backed and short-term, treasury bills carry:
- Minimal credit risk
- Low interest rate risk
How Treasury Bills Work
Treasury bills are issued at a price below their face value.
Example:
- Face value: $1,000
- Purchase price: $970
- Maturity: 6 months
At maturity, the investor receives $1,000, earning $30 as income.
This difference represents the investor’s return.
