1-Year Treasury Bonds — Safe Short-Term Investing Explained

What Are 1-Year Treasury Bills?

1-year (52-week) Treasury bills are short-term US government securities that mature in 12 months. They're the longest T-Bills available and one of the most popular safe investments — your money is back in a year with a guaranteed return.

Like all T-Bills, they're sold at a discount to face value — you pay less than $100 per unit and receive the full $100 at maturity. The difference is your interest.

1-year T-Bills are a strong alternative to bank CDs — they typically offer competitive or better yields, with the added benefit of state tax exemption and US government backing. For investors seeking a safe place to park cash for up to 12 months, they represent one of the most efficient options available.

How Does the Yield Work?

1-year T-Bill yields change at every auction and track Fed policy expectations:

In early 2026, 1-year T-Bills are yielding approximately 4.5–5.0%. Since they don't pay periodic interest, all your return comes as a lump sum at maturity — you pay ~$9,525 and receive $10,000 back in 12 months.

The yield reflects market expectations for Fed policy over the next year. If markets expect rate cuts, 1-year yields may fall below shorter T-Bill yields (an "inverted" curve).

Understanding Discount Pricing

Unlike Treasury notes and bonds that pay semiannual coupons, T-Bills use a discount mechanism. Here's how the math works:

If the annualized yield is 4.75%, you'd pay approximately $9,547 for a $10,000 face value T-Bill. At maturity, you receive the full $10,000 — the $453 difference is your interest income.

This all-at-maturity structure has practical implications. You don't receive any cash flow during the 12-month holding period, which means no reinvestment decisions or cash management during the term. For many investors, this simplicity is actually an advantage — set it, forget it, and collect your return in one year.

Auction Mechanics

52-week T-Bills are auctioned every four weeks, usually on Tuesdays. You can participate in two ways:

• Noncompetitive bid — you accept whatever yield the auction determines. This guarantees you'll receive the T-Bills, and it's what most individual investors choose.
• Competitive bid — you specify the yield you want. If the auction clears at or above your rate, you receive the T-Bills. If not, your bid is rejected.

The auction results are published immediately after the auction closes. Settlement typically occurs the following Thursday.

Key Features

1-Year T-Bills as a Money Market Alternative

Why T-Bills Often Beat Money Market Funds

Money market funds are the traditional go-to for cash management, but 1-year T-Bills offer several structural advantages:

Higher yield. Money market funds must maintain daily liquidity and diversification requirements that limit their yield potential. A 1-year T-Bill, by locking up your money for 12 months, typically offers 0.25–0.75% more.

Tax efficiency. Money market fund dividends are typically subject to both federal and state income tax. T-Bill interest is exempt from state and local tax. In a state like New York (combined city + state rate of ~12%), this adds meaningfully to your after-tax return.

Zero credit risk. Money market funds are generally very safe, but they're not guaranteed. The 2008 "breaking the buck" episode (when the Reserve Primary Fund fell below $1.00 per share) reminded investors that money market funds carry a small but real risk. T-Bills carry no such risk — they're direct obligations of the US Treasury.

Simplicity. No management fees, no expense ratios, no prospectus to read. You buy a T-Bill and receive your money back with interest in one year.

When Money Market Funds Win

Money market funds offer daily liquidity — you can access your money anytime without selling on the secondary market. If there's any chance you'll need the cash within 12 months, a money market fund is more practical. They also automatically reinvest, while T-Bill rollovers require periodic action (unless you set up auto-reinvestment on TreasuryDirect).

Who Should Buy 1-Year T-Bills?

1-year T-Bills work well for people who:

1. Want a safe place for money for ~12 months — a year is manageable and yields are competitive with or better than bank products
2. Value liquidity — while the maturity is 12 months, you can sell on the secondary market anytime
3. Want to lock in current rates — if you expect the Fed to cut rates, a 1-year T-Bill locks in today's yield
4. Don't want to freeze money for years — unlike TIPS or 10-year bonds, you get everything back in 12 months
5. Need a safe holding space for earmarked money — funds awaiting a major purchase, investment deployment, or tax payment

Practical Use Cases

Emergency fund extension. Keep 3 months of expenses in a high-yield savings account for immediate access, and put an additional 3–6 months in 1-year T-Bills for higher yield. If you need the T-Bill money, sell on the secondary market.

Tax payment reserve. If you're self-employed or have significant investment income, you know large tax bills are coming. Parking that money in 1-year T-Bills until the April deadline means it earns ~4.5–5.0% instead of sitting idle.

Down payment fund. Planning to buy a house in 12–18 months? A 1-year T-Bill keeps the money safe, growing, and guaranteed to be there when you need it. Unlike the stock market, there's zero risk of the money being worth less when you need it.

Bridge between investments. Sold an investment and need time to decide where to deploy the proceeds? A 1-year T-Bill earns meaningful interest while you research and wait for the right opportunity.

1-Year T-Bills vs Bank CDs

The main advantage: T-Bill interest is exempt from state and local income tax. In high-tax states like California or New York, this can add 0.3–0.5% to your effective return. CDs may offer promotional rates, but T-Bills offer more consistency and government backing beyond FDIC limits.

For amounts exceeding the $250,000 FDIC limit, T-Bills are strictly superior — they carry no counterparty risk regardless of amount.

1-Year T-Bills vs 2-Year Treasury Notes

2-year Treasury notes pay semiannual coupons and may offer slightly higher yields. But they tie up your money for twice as long. If you're unsure about your needs beyond 12 months, the 1-year T-Bill is the safer choice.

The coupon structure also matters. With a 2-year note, you receive two interest payments per year, creating reinvestment decisions. A 1-year T-Bill is completely hands-off — buy, wait, collect. For investors who value simplicity, this is a real advantage.

1-Year T-Bills vs 3-Month T-Bills

Shorter T-Bills (4-week, 13-week, 26-week) offer more frequent rollovers and maximum flexibility. But in a normal yield curve environment, they pay less. The 1-year T-Bill represents the "sweet spot" for many investors — long enough to capture higher yields, short enough to maintain reasonable flexibility.

However, if you expect interest rates to rise, shorter T-Bills let you reinvest at higher rates sooner. Rolling four 3-month T-Bills per year gives you four opportunities to capture rate increases, versus just one with a 1-year T-Bill.

Historical Yield Context

The current yield environment is historically attractive. Prior to 2022, 1-year T-Bills hadn't offered yields above 4% since before the 2008 financial crisis. Investors who remember the near-zero rates of 2020–2021 should recognize the opportunity.

Auto-Reinvestment and Rolling Strategy

TreasuryDirect offers an automatic reinvestment feature for T-Bills. When your 52-week T-Bill matures, the proceeds automatically purchase a new 52-week T-Bill at the next auction. This creates a perpetual rolling strategy that requires zero ongoing management.

You can set up auto-reinvestment for up to 2 years (two consecutive rolls). After that, you need to re-enable it. The feature is free and eliminates the risk of forgetting to reinvest maturing proceeds.

For more control, some investors manually manage their rollovers through a brokerage account, which lets them evaluate current yields before committing to another year.

Tax Considerations

T-Bill interest has a unique tax treatment:

• Federal income tax — yes, fully taxable as ordinary income
• State and local income tax — exempt
• Timing — interest is reported in the year the T-Bill matures, not when purchased

The maturity-year reporting creates a potential tax planning opportunity. A T-Bill purchased in April 2026 and maturing in April 2027 generates taxable income in 2027, not 2026. If you expect to be in a lower tax bracket next year (retirement, sabbatical, lower income), timing your T-Bill purchases accordingly can reduce your tax bill.

How to Buy 1-Year T-Bills

Same process as all Treasury securities:

1. TreasuryDirect.gov — set up an account and buy at auction, with automatic reinvestment available
2. Brokerage accounts — Fidelity, Schwab, Vanguard, etc. offer auction access and secondary market trading
3. Short-term bond ETFs — BIL, SGOV, SHV for diversified T-Bill exposure without managing individual maturities

52-week T-Bills are auctioned every 4 weeks. You can set up automatic reinvestment on TreasuryDirect so maturing bills roll into new ones seamlessly.

TreasuryDirect vs Brokerage

For buy-and-hold investors, TreasuryDirect is slightly more cost-effective — there are no fees or commissions. However, brokerage accounts offer easier secondary market access if you need to sell before maturity, better account management tools, and the ability to hold T-Bills alongside your other investments.

Most investors with an existing brokerage account find it more convenient to buy T-Bills through their broker, even though the cost is virtually the same.

Frequently Asked Questions

Are 1-year T-Bills risk-free?

They're as close to risk-free as any investment can be in terms of credit risk — the US government has never defaulted on its debt obligations. However, they carry inflation risk (your return might not keep up with rising prices) and opportunity cost (you might miss out on higher returns from riskier investments).

Should I buy 1-year T-Bills or a high-yield savings account?

For money you might need anytime, a high-yield savings account offers instant access. For money you can commit for 12 months, a 1-year T-Bill typically offers a higher yield plus state tax exemption. Many investors use both — savings account for immediate liquidity, T-Bills for planned cash reserves.

What happens if I need my money before the T-Bill matures?

You can sell on the secondary market through a brokerage account. The sale price depends on current rates — if rates have risen, you'll sell at a slight loss; if rates have fallen, you'll sell at a slight gain. Given the short duration, the price impact is minimal (typically less than 1%).

How do 1-year T-Bills compare to I-Bonds?

I-Bonds offer inflation protection (their rate adjusts with CPI) but have a 1-year lockup with no secondary market, a 5-year early withdrawal penalty, and a $10,000 annual purchase limit. T-Bills offer a fixed return with daily secondary market liquidity and no purchase cap. They serve different purposes — I-Bonds for inflation protection, T-Bills for predictable short-term returns.
