U.S. Treasury Securities

Treasury securities are debt obligations of the U.S. government—the safest fixed-income investments available. They are backed by the full faith and credit of the U.S. government and serve as the benchmark for other interest rates.

Why Treasuries Are the Safest

Types of Treasury Securities

Treasury Bills (T-Bills)

Discount Calculation Example:

• 26-week T-bill with 4% annualized discount
• Purchase price: $10,000 × (1 - 0.04 × 26/52) = $9,800
• Return: $200 over 6 months

Treasury Notes (T-Notes)

The 10-year Treasury note yield is the most important benchmark in fixed income—used for mortgage rates, corporate bonds, and economic analysis.

Treasury Bonds (T-Bonds)

Treasury Inflation-Protected Securities (TIPS)

TIPS protect against inflation by adjusting principal based on the Consumer Price Index (CPI).

TIPS Example:

• Buy $10,000 TIPS with 2% coupon
• CPI increases 3% over 6 months
• Principal adjusts to $10,150
• Semi-annual interest: 2%/2 × $10,150 = $101.50 (vs. $100 originally)

Tax Consideration: The principal adjustment is taxable in the year it occurs, even though you don't receive the cash until maturity ("phantom income").

Treasury STRIPS

STRIPS (Separate Trading of Registered Interest and Principal of Securities) are zero-coupon Treasury securities.

STRIPS Duration: A 20-year STRIP has a duration of 20 years—the maximum possible. This means extreme price sensitivity to interest rate changes.

Tax Treatment of Treasuries

This state tax exemption makes Treasuries particularly attractive for investors in high-tax states like California and New York.

Treasury Quotations

T-Bills (Discount Basis)

Quoted as annualized discount rate from par:

• Bid 4.05%, Ask 4.00% means dealer buys at 4.05% discount, sells at 4.00% discount

Notes and Bonds (32nds Pricing)

Quoted as percentage of par in 32nds:

• 99-16 = 99 + 16/32 = 99.5% of par = $995 per $1,000 face
• 101-08 = 101 + 8/32 = 101.25% of par = $1,012.50 per $1,000 face

Treasury Auctions

Most individual investors use non-competitive bids through TreasuryDirect.

In Practice: How Investment Advisers Apply This

Portfolio applications:

• Use T-Bills for short-term reserves and near-term liquidity needs
• Use T-Notes for intermediate-term objectives
• Use T-Bonds for long-term income (accept higher interest rate risk)
• Use TIPS for inflation-sensitive clients (retirees, pension plans)

Client considerations:

• High-tax state residents benefit from state tax exemption
• TIPS create taxable phantom income—better in tax-advantaged accounts
• STRIPS are best for specific future liabilities (e.g., college funding)
