3-Month Treasury Bills — The Safest Short-Term Investment

What Are 3-Month Treasury Bills?

3-month (13-week) Treasury bills are the shortest standard US government securities, maturing in just 90 days. They're the closest thing to a risk-free investment — backed by the US government with near-instant liquidity.

Unlike bonds and notes, T-Bills don't pay periodic interest. Instead, you buy them at a discount to face value and receive the full face value at maturity. The difference is your return.

Key Features

T-Bill Yields in 2026

T-Bill yields are set at weekly auctions and closely track the Federal Reserve's target rate. In early 2026, 3-month T-Bills are yielding approximately 4.5–5.0% annualized.

For a 3-month holding period, that translates to roughly 1.1–1.25% actual return (before taxes) or about 0.8–0.9% after federal tax, depending on your bracket.

Example: How Much Will You Earn?

Suppose you invest $10,000 in 3-month T-Bills at a 4.75% annualized yield:

Who Should Buy 3-Month T-Bills?

T-Bills are an excellent choice in several situations:

1. Parking Cash Temporarily

When you have money that you'll need in a few months for a specific goal — down payment, tuition, taxes — T-Bills let you earn a safe return instead of leaving it in a checking account.

2. Building a T-Bill Ladder

Buy T-Bills weekly or monthly with staggered maturities. Every few weeks, a batch matures and you receive cash plus returns that you can reinvest. This creates a steady stream of liquidity.

3. Testing the Treasury Market

If you've never bought government securities, 3-month T-Bills are a low-commitment way to learn the process through TreasuryDirect or your broker.

4. Safe Haven in Volatile Markets

When stocks are turbulent, T-Bills provide a calm harbor for a portion of your portfolio with virtually zero risk.

T-Bills vs Alternatives

T-Bills vs High-Yield Savings Accounts

T-Bills vs 1-Year Treasury Notes

1-year T-Bills and short-term notes have a longer holding period and often slightly higher yields. If you can lock up funds for 12 months, you'll typically earn more. If you need maximum flexibility — 3-month T-Bills are the better choice.

T-Bills vs Money Market Funds

Money market funds invest primarily in T-Bills and similar instruments but charge a management fee (typically 0.1–0.5%). Buying T-Bills directly avoids the fee, but money market funds offer more convenience and instant liquidity.

How to Buy 3-Month T-Bills

1. TreasuryDirect.gov — buy directly at weekly auctions
2. Brokerage accounts — Fidelity, Schwab, Vanguard all offer T-Bill purchases at auction or on secondary market
3. T-Bill ETFs — BIL (SPDR 1–3 Month), SGOV (iShares 0–3 Month) for hands-off exposure
4. Money market funds — indirect exposure with added convenience

3-month T-Bills are auctioned every week, so there's always a new opportunity to invest.

Auction Schedule

The US Treasury holds 13-week bill auctions every Monday (settlement on Thursday). You can set up automatic reinvestment on TreasuryDirect so maturing T-Bills are immediately rolled into new ones.

Risks and Limitations

T-Bills are essentially risk-free in terms of credit risk. The main limitations:

1. Inflation risk — after taxes, your return may not keep up with inflation
2. Short duration — you don't benefit from locking in rates if they decline
3. Reinvestment risk — when your T-Bill matures, the next auction may offer lower yields

The T-Bill Ladder Strategy

Instead of investing everything in a single auction, consider a ladder:

Week 1: Buy $3,000 in T-Bills Week 2: Buy another $3,000 Week 3: Buy another $3,000

From week 14 onward, you'll have T-Bills maturing every week, providing regular cash flow plus new money to reinvest. This smooths out yield fluctuations and ensures constant liquidity.

Tracking T-Bills in Freenance

Freenance automatically tracks your T-Bill investments:

• Current valuation with accrued discount
• Maturity reminders — get notified before your T-Bills come due
• Return analysis — compare with other investments in your portfolio
• Reinvestment planning — see when proceeds arrive and plan your next move

Stay on top of your short-term investments in one place.

Summary

3-month Treasury bills are the shortest and safest way to invest in the US government debt market. They're ideal for people who:

• Need a safe place for money they'll use soon
• Want better returns than a savings account for a short period
• Are building a diversified investment portfolio
• Want to test government securities before committing to longer maturities

With yields around 4.5–5% and the full backing of the US government, T-Bills remain an attractive alternative to bank deposits in 2026.

FAQ

What exactly is a 3-month Treasury bill?

A 13-week T-Bill is a short-term US government debt security that matures in roughly 91 days. You buy it at a discount to face value and receive the full face value at maturity, with the difference representing your return.

How often are 3-month T-Bills auctioned?

The US Treasury auctions 13-week bills every Monday, with settlement typically on the following Thursday. This weekly cadence makes it easy to build a ladder or roll maturing positions into fresh auctions.

Are 3-month T-Bills better than a high-yield savings account?

T-Bills usually offer slightly higher yields and the interest is exempt from state and local tax, which matters in high-tax states. Savings accounts win on instant access and zero minimums, so the right choice depends on whether you need the cash on a moment's notice.

What is the minimum amount needed to buy a 3-month T-Bill?

On TreasuryDirect the minimum purchase is $100, with additional increments of $100. Brokerage platforms typically follow the same minimums for auction purchases and the secondary market.

Can I sell a 3-month T-Bill before it matures?

Yes — T-Bills trade on a deep secondary market, so you can sell at any time through a brokerage. The price you receive depends on prevailing rates, but the short maturity keeps price movement small compared with longer notes.
