Understanding Treasury Bills: What They Are and How They Work

Treasury bills, often called T-bills, are short-term loans you give to the U.S. government. When you buy a Treasury bill, you're essentially lending money to the federal government for a set period. The government promises to pay you back with interest when the bill matures. This is one of the safest investments available because it's backed by the full faith and credit of the United States government.

Treasury bills come in different time frames. The most common durations are 4 weeks, 8 weeks, 13 weeks, 26 weeks, and 52 weeks. A 13-week Treasury bill means your money is loaned to the government for 13 weeks—about three months. After that period ends, you get your original money back plus interest earned. The interest rate changes based on market conditions and demand, so rates vary from one auction to the next.

Here's how the pricing works: Treasury bills are sold at a discount. This means you buy them for less than their face value. For example, you might pay $9,900 for a Treasury bill with a $10,000 face value. When it matures in 13 weeks, you receive the full $10,000. That $100 difference is your profit, which represents the interest you earned. As of late 2024, Treasury bill rates have ranged from about 4% to 5.3% annually, depending on the duration and market conditions.

The Treasury Department holds auctions where new Treasury bills are sold. These auctions happen regularly—bills maturing in 4 and 13 weeks are auctioned every week, while 26-week and 52-week bills are auctioned every other week. Billions of dollars change hands at these auctions. Individual investors can participate directly, or work with banks and brokers who handle the transactions.

Practical takeaway: Treasury bills are straightforward investments that provide a known return when held to maturity. Understanding the basic mechanics—that you're buying at a discount and receiving full face value at maturity—forms the foundation for evaluating whether they fit your financial situation.

Comparing Treasury Bills to Other Short-Term Investment Options

While Treasury bills are one option for short-term investing, several alternatives exist. Each has different risk levels, interest rates, and liquidity characteristics. Understanding how they compare helps you make decisions aligned with your financial goals.

Money market accounts are bank products that typically offer interest rates similar to or slightly lower than Treasury bills. As of 2024, many money market accounts pay between 4% and 5% annually. The key difference is that money market accounts are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor per bank, while Treasury bills aren't insured but are considered backed by the government itself. Money market accounts also provide easier access to your money—you can usually withdraw funds with minimal notice, whereas Treasury bills have set maturity dates.

Certificates of deposit (CDs) are another short-term option. Banks offer CDs with terms ranging from a few months to several years. Currently, short-term CDs (3 to 6 months) pay rates comparable to Treasury bills, around 4% to 5% annually. CDs also come with FDIC insurance. The trade-off is that withdrawing money early from a CD typically results in an early withdrawal penalty. Treasury bills don't have this penalty—you simply wait until maturity or sell them on the secondary market.

High-yield savings accounts (HYSA) have become increasingly competitive. Many online banks now offer rates between 4% and 5.35% annually, making them comparable to Treasury bills in terms of returns. These accounts are FDIC insured and provide daily liquidity. You can add or withdraw money whenever you want without penalties. The downside is that rates can change at any time, whereas the rate on a Treasury bill you've purchased is locked in until maturity.

Commercial paper is a short-term debt instrument issued by corporations. It typically offers slightly higher interest rates than Treasury bills—sometimes 0.25% to 0.5% more—but carries corporate credit risk. If the company faces financial trouble, you could lose money. Treasury bills carry no default risk from the issuer perspective.

Here's a quick comparison table of features:

• Treasury Bills: 4% to 5.3% rates (as of late 2024), no FDIC insurance, fixed maturity dates, no early withdrawal penalty, very low risk
• Money Market Accounts: 4% to 5% rates, FDIC insured up to $250,000, daily liquidity, variable rates
• Short-term CDs: 4% to 5% rates, FDIC insured up to $250,000, fixed rates, early withdrawal penalties
• High-yield Savings: 4% to 5.35% rates, FDIC insured up to $250,000, daily liquidity, variable rates
• Commercial Paper: 4.25% to 5.8% rates, no insurance, corporate credit risk, 1 to 270-day terms

Practical takeaway: Treasury bills aren't necessarily the best choice for everyone. If you need daily access to your money or prefer FDIC insurance, high-yield savings accounts or money market accounts may work better. If you want a locked-in rate with no penalties, Treasury bills offer that advantage. Consider your liquidity needs, insurance preferences, and timeline when choosing.

How to Purchase Treasury Bills Directly

The U.S. Treasury Department allows individuals to purchase Treasury bills directly through a website called TreasuryDirect. This approach eliminates intermediaries like brokers, meaning you don't pay commissions or fees. This is often the lowest-cost way to buy Treasury bills.

To purchase through TreasuryDirect, you first create an account on the website (treasurydirect.gov). The registration process requires basic information including your Social Security number, date of birth, and bank account details. The account setup typically takes 5 to 10 minutes. You'll need a valid email address and to establish a username and password.

Once your account is set up, you can place bids for Treasury bills during auctions. You specify which bill you want (4-week, 13-week, 26-week, or 52-week), how much you want to purchase, and whether you're placing a competitive or non-competitive bid. Most individual investors use non-competitive bids, which means you're willing to accept whatever rate the auction determines. This nearly guarantees your bid will be filled. Competitive bids let you specify the rate you're willing to accept, but there's a risk your bid won't be accepted if your rate is too low.

The minimum investment through TreasuryDirect is $100, with increases in $100 increments after that. So you could purchase $100, $200, $300, or any amount in $100 increments. There's technically no maximum limit for individuals, though very large purchases might require discussion with Treasury officials.

Here's the timeline for a typical auction:

• Announcement phase: The Treasury announces the auction details, typically on a Tuesday or Wednesday
• Bidding period: You can place your bid online through TreasuryDirect from the announcement through the bid deadline (usually the next day)
• Auction completion: The Treasury conducts the auction and determines the rate
• Issue date: Three days after the auction, Treasury bills are issued and money is withdrawn from your bank account
• Maturity: Your Treasury bill matures on its scheduled date, and funds are deposited into your bank account

If you want to sell your Treasury bill before it matures, you can transfer it from TreasuryDirect to a brokerage account (a process called "stripping") and then sell it on the secondary market. However, if interest rates have risen since you purchased the bill, you'll receive less than you paid because the bill's value drops when rates increase. Conversely, if rates have fallen, you can sell for more than your original investment.

Practical takeaway: TreasuryDirect offers the most direct route to buying Treasury bills with no fees. Set aside
